Description

  TECHNICAL FIELD The present invention relates to a root crop harvesting machine for extracting a crop from a field, removing a foliage during transportation, and harvesting the crop.

Conventional root crop harvesting machines transport crops that have been extracted and harvested from the field, regulate the upward transport of the crops with a shoulder alignment device, align the cutting positions of the foliage, and cut the crops with a pair of left and right rotating blades. There is a technique of dropping the remaining leaves remaining on the dropped crop and winding the remaining leaves on a remaining leaf processing roller while being conveyed by the remaining leaf processing conveyor. (Patent Document 1)
On one of the pair of left and right rotating blades, when cutting and dropping the foliage, a disk made of a soft material is brought into contact with the shoulder of the crop, and the side with the remaining leaf of the crop faces the remaining leaf processing roller. The configuration is such that the leaf is dropped in a posture, and the remaining leaf cannot be brought into contact with the remaining leaf processing roller, thereby reducing the occurrence of an operation of manually removing the remaining leaf.

JP 2013-27348 A

  However, in the root crop harvesting machine described in Patent Document 1, since the positions where the left and right rotating blades cut the foliage are constant, the traveling speed of the machine body and the transport speed of the crop are increased in order to increase work efficiency. In this case, the crop may fall not directly below but toward the rear of the aircraft due to inertia when the foliage is cut. As a result, the crop cannot be dropped on the removing and conveying conveyor and falls off the conveying path, so that it is necessary to return the crop to the conveying path, and there is a problem that extra time and labor are required.

  Further, depending on the drop position, there is a problem that the crop is scratched or broken and the commercial value is reduced, or the product is no longer a commercial product and the yield is reduced.

  Also, if the position of falling onto the left-leaf processing conveyor is closer to the front side of the machine, the chance (contact time) of contacting the remaining-leaf removal action range by the remaining-leaf processing roller is reduced, so that the remaining leaves are left. There is a problem that the crop is transported as it is and it is necessary to perform an operation of removing the remaining leaves manually.

  In addition, since the transport speed of the pull-out transport device and the remaining leaf processing conveyor is configured to be linked to the traveling speed, when harvesting the crop at the above-described high speed, or when the space between the crops is narrow, the so-called inter-strain, the preceding crop is May fall on the conveyor for treating remaining leaves and move from there, and the following crops may fall before the fall space is opened, and the crops may collide with each other and be damaged, reducing the commercial value or reducing the yield. Or have a problem.

  In addition, the preceding crop from which the remaining leaves have been removed by the remaining leaf processing roller prevents the subsequent crop from approaching the remaining leaf processing roller, and the crop is conveyed with the remaining leaves remaining, so that the crop is manually fed. There is a problem that it is necessary to perform an operation for removing the remaining leaves.

  The tension plates 53L, 53R are formed with slots in the transmission cases 37, 37, and the mounting shafts 53a, 53a are mounted for position adjustment with detachable members such as bolts, and plates are attached to the ends of the mounting shafts 53a, 53a. The body 53b is formed by welding.

  The tension plates 53L and 53R may be provided substantially in parallel with the left and right positioning devices 54L and 54R. However, when the tension plate 52R is provided in front of the positioning device 53R on the outside of the fuselage, the positioning of the inside of the fuselage is performed. When the tension plate 52L of the device 53L is provided on the rear side of the fuselage with respect to the tension plate 52R of the positioning device 53R, when the large-diameter foliage part h passes between the left and right of the positioning devices 54L and 54R, the tension plate 52L or the tension plate is used. Since the alignment chain 48 and the alignment guide body 52 move to the side where the plate 52R is not provided, even if the ginseng foliage h is large in diameter, it can be prevented from being caught by the alignment devices 54L and 54R, and the machine is stopped. There is no need to remove the foliage h that has been bitten, thereby improving work efficiency.

  In addition, if the tension of the tension plates 53L, 53R is set to be weaker than the tension of the urging springs 50, 50, the alignment chains 48, 48 are properly adjusted when a load is applied through the large-diameter foliage h. It is possible to bend and retreat to the position, prevent being caught by 54L, 54R, and eliminate the need to stop the body and remove the caught foliage h, thereby improving work efficiency.

  An elongated hole is formed in the transmission case 37 near the alignment drive sprockets 42 and outside the alignment guides 52, 52, and the surfaces of the alignment guides 52, 52 are formed in the elongated holes. At the time of position adjustment, the left and right scrapers 55, 55 for dropping the cuttings and mud, etc. of the foliage h attached to the surface are aligned along the trajectories of the alignment guide bodies 52, 52.

  By arranging the scrapers 55, 55 in a rearward-downward inclined posture, the scraps of the foliage h and mud can be easily dropped downward.

  Left and right cutting blade rotation shafts 56, 56 are provided at positions rearward of the shoulder alignment devices 54L, 54R of the first left and right gear units 38, 38, and left and right bearings 57, 57 are mounted on the cutting blade rotation shafts 56, 56. Attach it freely. Then, left and right support plates 59, 59 are attached to the left and right bearings 57, 57, and left and right foliage cutting blades 60L, 60R are attached to the support plates 59, 59, thereby forming a foliage cutting device 61.

  Note that the left and right foliage cutting blades 60L, 60R are circular rotary blades, and the edges of the left and right shoulder alignment devices 54L, 54R are overlapped near the left and right central portions, so that the ginseng foliage h can be removed. It cuts and cuts the carrot to drop it. The ginseng harvester of this example has a configuration in which the cutting heights are aligned by contacting the bottoms of the left and right shoulder aligning devices 54L and 54R, so that the left and right foliage cutting blades 60L and 60R are higher than the hairline of the ginseng foliage h. In this configuration, the foliage h is cut at the upper side.

  Therefore, in the carrot which falls after cutting the foliage h, the so-called residual leaves hr are left uncut of the foliage h. It is necessary to remove the residual leaves hr before shipping, and it is necessary for an operator to manually remove the residual leaves using a kitchen knife or the like after the harvesting operation. With this arrangement, the remaining leaves hr can be automatically removed during the harvesting operation.

  However, depending on the position where the ginseng falls to the remaining leaf processing unit E, there is not enough chance to come into contact with the remaining leaf processing operation position when transported in the remaining leaf processing unit E, and in a state where the remaining leaf hr remains. It is sent from the remaining leaf processing unit E to a post-process, and it becomes necessary for the worker to manually remove the remaining leaf hr after harvesting, which requires extra labor and requires extra time for preparation for shipping. There is a problem to be solved.

  In order to solve this problem, as shown in FIGS. 14 (a) and 14 (b), the left and right foliage cutting blades 60L and 60R constituting the foliage cutting device 61 are provided on the outside of the body (one side of the body). The position of the left foliage cutting blade 60L provided is fixed. The front end of the cutting transmission case 600 for transmitting the driving force is quickly attached to the rear upper portion of the left shoulder alignment device 54L, and the left foliage cutting blade 60L is attached to the rear lower portion of the cutting transmission case 600. I do.

  In the cutting transmission case 600, a driving sprocket 601 receiving driving force from the left shoulder aligning device 54L, a driven sprocket 602 for rotating the left foliage cutting blade 60L, and the driving sprocket 601 and the driven sprocket 602 are provided. A transmission chain 603 that is wound and transmits a driving force is arranged.

  On the other hand, the right foliage cutting blade 60R provided on the inner side of the fuselage (the other side of the fuselage) adjusts the position of the left foliage cutting blade 60L in the longitudinal direction of the fuselage to change the cutting timing of the foliage h. It is mounted via the device 604. Note that the front and rear adjustment range of the right foliage cutting blade 60R is such that the left foliage cutting blade 60L and the front end are aligned in the left and right direction when moved forward, and the left foliage cutting blade 60L is moved even rearmost. Is a range that partially overlaps in plan view.

  A base portion of a fixed-side transmission case 605 is provided from the rear upper portion of the right shoulder aligning device 54R on the other side of the body and toward the rear side, and an upper end portion of the fixed-side transmission case 605 has an end portion. A rotation-side transmission case 609 whose side faces the outside of the machine is rotatably mounted. A right foliage cutting blade 60R is attached to a lower portion on the end side of the rotation-side transmission case 609.

  Inside the fixed-side transmission case 605, a fixed-side input sprocket 606 that receives a driving force from the right shoulder aligning device 54R, a fixed-side output sprocket 607 that outputs a driving force, and the fixed-side input sprocket 606 and the fixed side A fixed-side transmission chain 608 wound around the output sprocket 607 and transmitting the driving force is arranged.

  Further, inside the rotation-side transmission case 609, a rotation-side input sprocket 610 that receives a driving force from the fixed-side transmission case 605, and a rotation-side output sprocket 611 that rotates the right foliage cutting blade 60R. A rotation-side transmission chain 612 that is wound around the rotation-side input sprocket 610 and the rotation-side output sprocket 611 and transmits a driving force is arranged.

  Further, a rack gear 613 that determines a rotation range of the rotation-side transmission case 609 is provided outside the rotation-side transmission case 609, and a rotation motor 615 that includes a pinion gear 614 that meshes with the rack gear 613 is provided. The moving device 604 is configured. The rotation motor 615 is a forward / reverse rotation motor.

  Note that the outer side of the fuselage, that is, the left side foliage cutting blade 60L may be provided with a device having the same configuration as the moving device 604 so that the front and rear position can be adjusted. However, if the position of one of the left and right cutting blades is changed, Since the timing at which the foliage h is cut is changed, only the foliage cutting blade 60R on the inside (right side) of the fuselage is configured to be adjustable in the front-rear position in order to suppress an increase in the number of parts and cost in the example of the present application.

  In addition, since a dust-proof cover is provided on the outside of the body of the drawing and conveying device 24 to prevent foreign substances such as soil and leaf dust from scattering, it is difficult to adjust the front and rear positions of the foliage cutting blade 60L by the moving device 604. is there. Therefore, in the present example, only the foliage cutting blade 60R on the inner side (right side) of the machine is configured to be adjustable in the front-rear position.

  With the above-described configuration, when the moving device 604 is operated to move the right foliage cutting blade 60R backward, the left and right foliage cutting blades 60L and 60R are overlapped and the cutting action position for cutting the foliage h is shifted toward the rear side of the machine body. Can be changed.

  By cutting the foliage h to the rear of the machine when harvesting carrots at low speed, the ginseng that is cut off the foliage h and falls near the rear end of the body of the remaining leaf processing unit E described below. That is, the remaining leaf processing roller 75 can be dropped near the starting end of the remaining leaf processing roller 75, so that the remaining leaf hr can be removed using substantially the entire width of the remaining leaf processing roller 75 in the front-rear direction. Therefore, the time and labor required for the operation of removing the remaining leaves hr from the carrots after harvest can be reduced.

  Also, at the time of high-speed work, etc., the front and rear positions of the left and right foliage cutting blades 60L and 60R are aligned, the cutting action position of the foliage part h is set closer to the body front side, and the fall of carrot is accelerated, so that the front and rear of the remaining leaf processing part E is achieved. It can be configured to receive a carrot that falls using the width.

  As a result, the fallen ginseng is conveyed toward the left and right sides of the aircraft while being scattered in the front-rear direction, so that it is easy to prevent that there is a preceding ginseng at the fall position of the succeeding ginseng, the carrots collide with each other, and are damaged. It is prevented that the commercial value is reduced.

  Further, since the fixed-side transmission case 605 and the rotation-side transmission case 609 that constitute the moving device 604 are arranged to avoid the transfer path of the pull-out transfer device 24 and the shoulder alignment devices 54L and 54R, they interfere with the transfer of ginseng. This prevents the ginseng from being damaged by the contact and reducing the commercial value.

  Further, the end side of the rotation-side transmission case 609 is configured to rotate so as to swing back and forth, so that the fore-and-aft position of the foliage cutting blade 60R on the right side of the body can be adjusted, and the foliage cutting blade on the left side of the body is adjustable. Since it is possible to suppress an increase or decrease in an overlapping area between the foliage cutting blade 60R and the foliage cutting blade 60R on the right side of the machine body, the foliage h can be reliably cut.

  Further, left and right foliage transport drive pulleys 62, 62 are provided on the first left and right output shafts 40, 40, and the left and right foliage transport drive pulleys 62, 62 are provided on the front side of the body with respect to the first left and right gear units 38, 38 and above the shoulder aligning devices 54L, 54R. The driven pulleys 63 are rotatably mounted. The left and right foliage transport belts 64 are wound endlessly around the left and right foliage transport drive pulleys 62, 62 and the left and right foliage transport driven pulleys 63, 63, so that the foliage of ginseng leaves from the pull-out transport device 24. A leaf conveying device 65 that takes over the h and discharges it to the rear of the machine is configured on the upper outer periphery of the left and right transmission cases 37, 37 and below the conveying terminal side of the pull-out conveying device 24.

  Further, left and right residual leaf transport drive pulleys 67, 67 are provided at the upper ends of the left and right first output shafts 40, 40, and left and right residual leaf transport driven pulleys 67, 67 are provided above the left and right transmission cases 37, 37. Are rotatably mounted, and a plurality of left and right residual leaf transport tension pulleys 68, 68,... Are mounted between the left and right residual leaf transport drive pulleys 66, 66 and the left and right residual leaf transport driven pulleys 67, 67. The left and right remaining leaf transport belts 69, 69 are endlessly connected to the left and right residual leaf transport drive pulleys 66, 66, the left and right residual leaf transport driven pulleys 67, 67, and the left and right residual leaf transport tension pulleys 68, 68. By being wound, the remaining leaf transport device 70 that clamps the upper part of the foliage and transports it to the rear of the machine is configured above the leaf discharge transport device 65.

  A foliage shooter 71 that discharges the foliage cut by the foliage cutting device 61 from the terminal ends of the foliage transporting device 65 and the remaining leaf transporting device 70 to a field is provided, and a foliage cutting section D is configured.

  With the above configuration, the left and right alignment drive sprockets 42, 42 are arranged at positions separated from the left and right gaps of the shoulder alignment devices 54L, 54R through which the foliage h passes, so that the alignment drive sprockets 42, 42 Since the stems and leaves h are not entangled with the second output shafts 41 and 41 to stop the shoulder aligning devices 54L and 54R, the harvesting operation is not interrupted, and the working efficiency is improved.

  Further, by making the alignment driving sprockets 42, 42 smaller in diameter than the alignment alignment driven sprockets 45, 45 and the alignment tension sprockets 47, 47, the alignment alignment drive sprockets 42, 42 are further left and right of the shoulder alignment devices 54L, 54R. Since it is separated from the interval, it is possible to further prevent the foliage portion h from becoming entangled with the alignment drive sprockets 42, 42 and the second output shafts 41, 41, and the working efficiency is further improved.

  By providing the right and left biasing springs 50 for biasing the alignment driven sprockets 45, the left and right alignment chains 48, 48 are provided when the foliage h contacts the shoulder alignment devices 54L, 54R. Can be absorbed, and the alignment chains 48, 48 immediately return to the tensioned state, so that the shoulder alignment devices 54L, 54R can reliably remove ginseng even when the foliage h having different diameters passes continuously. The foliage h can be received, the cutting positions of the ginseng foliage h are properly aligned, the foliage h is appropriately cut, and there is no need to remove the foliage h in a later process, thereby improving the work efficiency. .

  In addition, the tension of the biasing springs 50, 50 is adjusted by moving the left and right receiving plates 49, 49 in the front-rear direction, so that the growth status of the carrot and the diameter of the foliage h depending on the cultivar, the weather, and the like. Since the tension can be changed appropriately according to the working conditions of the work place such as soil, etc., the foliage remaining on the ginseng in the later process can be obtained by properly aligning the foliage cutting position of ginseng and cutting the foliage h reliably. There is no need to remove h, and work efficiency is improved.

  Further, holes 44, 44 in the left and right direction of the machine are formed in the left and right alignment frames 43, 43, and the rotating shafts 46, 46 provided with the alignment driven sprockets 45, 45 in the holes 44, 44 are movable. With this arrangement, in a state where a load is not applied, the alignment-driven driven sprockets 45, 45 urged by the urging springs 50, move toward the conveying path of the foliage h, so that the small-diameter foliage h passes through. In this case, the shoulder aligning devices 54L and 54R can receive the foliage h and properly align the cutting positions of the ginseng foliage h, eliminating the need to remove the foliage h remaining on the ginseng in a later process, thereby improving work efficiency. I do.

  Also, when a large load is applied to the left and right shoulder alignment devices 54L, 54R when the large-diameter foliage h passes through, the alignment driven sprockets 45, 45 move the foliage h along the holes 44, 44. Moving in a direction away from the shoulder aligning devices 54L, 54R, the front-to-left spacing is widened, and the foliage h can be prevented from being caught in the gaps between the shoulder aligning devices 54L, 54R. There is no need to remove the foliage h that has been bitten, thereby improving work efficiency.

  When it is known before the harvesting operation that the foliage h of the carrot is large in diameter before the harvesting operation, the alignment driven sprockets 45 are moved away from the left and right sides of the left and right shoulder alignment devices 54L and 54R. By moving the shoulder aligning devices 54L and 54R to increase the left-right spacing on the upper side in the transport direction, the shoulder aligning devices 54L and 54R can be prevented from biting the foliage h, and the clogged foliage h is removed. No work is required, and work efficiency is improved.

  The guide cover 51 is attached to each of the plurality of links 48a constituting the alignment chains 48, 48 to form the alignment guide body 52, so that the guide cover 51 at an arbitrary position can be freely attached and detached. Even if a part of the guide cover 51 is damaged, proper alignment performance is maintained only by replacing the guide cover 51 with a new guide cover 51, and the foliage h is appropriately cut, thereby improving work efficiency.

  Further, since there is no need to replace the entire alignment guide body 52, cost can be reduced.

  Further, since the attachment and detachment of the guide cover 51 can be performed manually without using a tool, the replacement operation can be easily performed.

  Since the guide cover 51 has a U-shape in front view that covers the contact surface between the upper and lower surfaces of the alignment chain 48 and the foliage h, a space is formed between the guide cover 51 and the alignment chain 48. Since it does not occur, the foliage h is sandwiched between the guide cover 51 and the alignment chain 48, so that the ginseng can be prevented from being aligned at an appropriate cutting position and the foliage h can be prevented from being left uncut. There is no need to perform the work of removing the part h, and the work efficiency is improved, and the root of the ginseng can be prevented from being cut off, thereby improving the commercial value of the ginseng.

  Further, a convex R portion 51a and a concave R portion 51b are formed on the guide cover 51, and the convex R portion 51a of the subsequent guide cover 51 is brought close to the concave R portion 51b of the front guide cover 51. When the alignment chain 48 moves around the alignment driven sprocket 45 or the like along an arc orbit, the guide covers 51 can follow and move, so that the shoulder alignment devices 54L and 54R Since it operates at a constant peripheral speed, the cutting position of the foliage h of the carrot can be properly adjusted in response to the foliage h, eliminating the need to remove the foliage h remaining on the ginseng in a later process, thereby improving work efficiency. I do.

  Further, by providing the protruding portion 51c protruding toward the convex R portion 51a, when the alignment chain 48 moves around the alignment driven sprocket 45 or the like in an arc path, the guide covers 51 are connected to each other. Since the protrusion 51c covers the space formed between the front and rear, the foliage h is sandwiched in the space between the front and back of the guide covers 51..., The carrot is not aligned at an appropriate cutting position, and the foliage h is cut off. It is possible to prevent the carrots from being left, and it is not necessary to perform the operation of removing the foliage h in a post-process, so that the work efficiency is improved, and the root of the ginseng can be prevented from being cut off, and the commercial value of the ginseng is improved.

  Since the left and right tension plates 53L, 53R are provided in the winding region 18i of the alignment chains 48, 48, the alignment chains 48, 48 are pressed from the winding region 18i. When passing, the alignment chains 48, 48 of the portions not pressed by the tension plate 53L or the tension plate 53R can be retracted in the direction of the alignment drive sprockets 42, 42, so that the foliage h is moved by the shoulder alignment devices 54L, 54R. There is no need to stop the fuselage to remove the foliage h that has been caught between the left and right sides, and the work efficiency is improved.

  Further, by providing the left and right scrapers 55, 55 for scraping off debris such as debris of the foliage portion h and mud attached to the alignment guide bodies 52, 52 which move on the outer circumference of the alignment drive sprockets 42, 42, Impurities attached to the alignment guide bodies 52, 52 can be removed at a position away from the movement path of the foliage h, so that fragments of the foliage h are prevented from entangled with the respective parts of the shoulder alignment devices 54L, 54R. This eliminates the need to stop the airframe and remove the entangled foliage of the foliage part h, thereby improving the work efficiency, preventing the mass of mud from damaging the root of ginseng, and improving the commercial value of ginseng.

  Further, since the mounting positions of the scrapers 55, 55 can be changed along the long holes, the scrapers 55, 55 are set at optimal positions according to the average diameter of the foliage h of the ginseng in the field where the harvesting operation is performed. Then, the above-described effect is further improved by reliably removing foreign substances such as debris and mud of the foliage part h from the alignment guide body 52 and the office work 52.

  And the leaf discharge chute 71 which discharges the leaves (cut foliage h) cut from the carrots by the foliage cutting device 61 to the field discharges the foliage to the dug side (the side where the ginseng has been harvested). As a result, the ejected foliage falls on the carrot on the undigged side (the side on which ginseng is not harvested), and the ejected leaves fall on the left and right holding conveyor belts 19, 19 and the left and right. Since it is possible to prevent the harvesting section C from being entangled with the driven pulleys 17, 17 and the like to hinder the harvesting operation, work efficiency is improved, and the discharged leaves falling on the ginseng impede the visibility of the harvested ginseng. Can be prevented.

  In the transmission cases 37, 37, the foliage h conveyed by the remaining leaf conveying device 70 falls down in the lateral direction of the machine body, and the foliage h is prevented from being conveyed to the rear of the machine. A leaf receiving plate 177 having a front-rear length substantially the same as the front-rear direction of the device 70 is provided on each of the left and right sides. Since the leaf receiving plate 177 has the foliage receiving portion 177 that receives the foliage h when the foliar portion h being transported falls down, the foliage h is transported by the remaining leaf transporting device 70 to the transport terminal portion. Is discharged to the field through the leaf discharge shooter 71.

  Next, the remaining leaf processing unit E will be described.

  As shown in FIGS. 1 to 6, front and rear remaining leaf processing frames 72, 72 are provided below the foliage cutting device 61, and a first roller 73 a is provided between the front and rear left and right sides of the remaining leaf processing frames 72, 72. Is attached rotatably. A second roller 73b is rotatably mounted between the front and rear left and right sides of the remaining leaf processing frames 72, 72 and below the first remaining leaf processing roller 73a.

  Then, an endless belt 74 made of an elastic material such as rubber or urethane is wound around the first roller 73a and the second roller 73b endlessly. Further, a remaining leaf processing roller 75 for sandwiching the remaining leaf hr remaining in the ginseng with the remaining leaf processing belt 74 and rotating and cutting the remaining leaf hr is attached to the upper part of the remaining leaf processing belt 74, and the remaining leaf taken over from the foliage cutting part D is attached. A left-leaf processing conveyor 76 that conveys the hr from the outside of the machine to the left and right inside while processing the hr.

  Further, a removal transport motor 620 for rotating the second roller 73 is provided on the rear side of the body of the remaining leaf processing conveyor 76, so that the remaining leaf processing unit E is configured. The removal conveyance motor 620 is a variable rotation motor whose rotation speed can be changed.

  The left-leaf processing conveyor 76 is inclined about 2 to 5 degrees from one side of the machine body to the other side.

  The front end of the remaining leaf processing conveyor 76 is located at substantially the same position as the front end of the left and right foliage cutting blades 61L and 61R, or slightly forward of the front end of the left and right foliage cutting blades 61L and 61R. Then, the rear end portion is configured to be located on the rear side of the fuselage with respect to the left and right foliage cutting blades 61L and 61R.

  Thereby, when performing harvesting work at a high vehicle speed, or when the machine body tends to sway with many irregularities in a field scene, even if the ginseng cut off the foliage h falls behind the machine body due to inertia, the remaining leaf processing conveyor Since the ginseng falls within the front-rear width of 76, it is not necessary to return the ginseng that has deviated from the transport route to the route, thereby improving work efficiency.

  Further, since the ginseng is less likely to fall on the aircraft, the ginseng is prevented from being damaged by the fall, and a decrease in commercial value is reduced.

  In addition, when ginseng falls to the front side of the fuselage from the front end of the remaining leaf processing conveyor 76, the ginseng falls to the sorting and transporting unit F. Therefore, although it is necessary to remove the remaining leaves hr after harvesting, it does not deviate from the transport path. Therefore, the working efficiency is not easily reduced.

  In addition, since the fallen ginseng moves by the drive and the tilting movement of the remaining leaf processing belt 74, the movement of the ginseng does not stop on the remaining leaf processing conveyor 76, and there is no need to manually move the stopped ginseng. , Work efficiency is improved. In addition, since the remaining leaf processing conveyor 76 is slightly inclined (about 2 to 5 degrees), the remaining leaf processing conveyor 76 can be inclined with respect to the ground even if the aircraft is tilted in the left and right side direction depending on the condition of the field. Since the carrot remains in a substantially horizontal state, the ginseng does not stagnate on the residual leaf processing conveyor 76 or move in a direction opposite to the transport direction of the residual leaf processing conveyor 76, and such ginseng is manually transferred to the transport path. There is no need to return, and work efficiency is improved.

  With the above configuration, the remaining leaf processing roller 75 constituting the remaining leaf processing conveyor 76 cuts out the remaining leaves of the carrots that have been cut off by the foliage cutting device 61, so that the operation of manually removing the remaining leaves after the harvesting operation is omitted. Work efficiency can be improved.

  Further, since the remaining leaf processing belt 74 constituting the remaining leaf processing conveyor 76 is made of an elastic material such as rubber or urethane, even if the foliage h is cut off by the foliage cutting device 61 and the ginseng falls, the remaining leaf processing is performed. Since the belt 74 reduces the impact of the fall, the ginseng is prevented from being damaged by the impact of the fall, and the quality of the ginseng is improved.

  A control configuration that more reliably cuts the foliage h and removes the residual leaves hr in accordance with the traveling speed and the ginseng harvesting pace by using the pull-out transport unit C, the foliage cutting unit D, and the remaining leaf processing unit E having the above configuration. Will be described.

  As shown in FIG. 20, when the output of the HST 150 increases or decreases due to the detection of the lever potential 13a of the traveling operation lever 13, the control device 200 calculates the traveling speed (vehicle speed) each time. At the same time, the rotation motor 615 is rotated forward or backward in accordance with the increase or decrease of the traveling speed, and the right foliage cutting blade 60R is moved to the front and rear position suitable for the traveling speed.

  Thereby, when the running speed increases, the cutting position of the foliage portion h by the foliage cutting device 61 becomes closer to the front side of the machine body, and the falling ginseng can be received by utilizing the front and rear width on the remaining leaf processing conveyor 76. It is possible to prevent the ginseng from coming off the route and to prevent the ginseng that has accumulated due to the removal of the remaining leaves hr from being injured by contact with the following ginseng.

  In addition, when the traveling speed decreases, the cutting position of the foliage h by the foliage cutting device 61 is shifted toward the rear side of the machine body, so that the remaining leaves hr can be removed using substantially the entire width of the front and rear width of the remaining leaf processing roller 75. Since the remaining leaves hr are less likely to remain on the carrots, the time and labor required for the post-harvest removal operation can be reduced.

  The front and rear positions of the right foliage cutting blade 60R may be changed in accordance with the operation position of the traveling operation lever 13 detected by the lever potentiometer 13a. At this time, if a cutting potion 616 for detecting the turning angle of the turning side transmission case 609 is provided, and the turning motor 615 is stopped by detecting the cutting potion 616, the right foliage cutting blade 60R is set to the traveling speed. It is stopped at a corresponding appropriate position, and the cutting accuracy of the foliage h is improved.

  In the above description, the traveling speed is calculated using the lever potentiometer 13a. The traveling speed may be calculated from a distance between two GPS points in a predetermined time, or a left and right drive transmitting the left and right crawlers 6L and 6R. A method of calculating the traveling speed by detecting the number of rotations of the shafts 9, 9 with a rotation sensor or the like may be used.

  Alternatively, a position where the operation amount is equal to or more than a predetermined amount from the neutral position of the traveling operation lever 13 is defined as a “high-speed work area”, and a position from below to the neutral position is defined as a “low-speed work area”, as shown in FIG. In the “high-speed work area”, if the right foliage cutting blade 60R moves forward, and in the “low-speed work area”, the right foliage cutting blade 60R moves rearward, the control becomes simple and the control device 200 Can be made inexpensive, and an increase in extra parts can be suppressed.

  Although the above is the control configuration of the control device 200, the vicinity of the base of the traveling operation lever 13 and the base side of the rotation-side transmission case 609 are connected by a cooperation wire (not shown), and the operation amount of the traveling operation lever 13 is reduced. In addition, a configuration may be used in which the front and rear positions of the right foliage cutting blade 60R change.

  In the above-described configuration, when the traveling operation lever 13 is operated to the speed increasing side (the front side of the machine body), the cooperation wire is configured to rotate the rotation side transmission case 609 to the front side of the machine body. The rotation-side transmission case 609 may be biased rearward by a spring (not shown) or the like so as to rotate the rotation-side transmission case 609 to the rear of the body when operated to the rear of the body. .

  Alternatively, a configuration may be adopted in which the front and rear positions of the right foliage cutting blade 60R are moved back and forth based on the ginseng plant between the left and right crop sensors 201 instead of the running speed.

  As shown in FIG. 22, when the distance between the ginseng strains is wide, the cutting of the foliage h of the following ginseng is performed while the preceding ginseng is moving to the area where the remaining leaves hr are removed. The cutting blade 60 </ b> R is moved to the rear side of the machine body, and the remaining leaves hr of the following carrot are surely removed over the entire width before and after the remaining processing roller 75.

  On the other hand, when the distance between the plants is narrow, the cutting interval of the foliage h of the front and rear ginsengs is short, and the subsequent ginseng tends to collide with the preceding ginseng. Therefore, the right foliage cutting blade is used to cut the foliage h as soon as possible. The 60R is moved to the front side of the fuselage to prevent the carrots from being damaged by contact.

  In addition, if the space between the plants detected by the crop sensor 201 is narrow, a plurality of carrots will ride on the remaining leaf processing conveyor 76. When a plurality of ginsengs are in contact with the remaining leaf processing roller 75, the following ginseng is brought into contact with the preceding ginseng and transported together, and is sent to a sorting transport conveyor 87 described below without processing the remaining leaves. Therefore, there is a problem that the remaining leaves hr tend to remain on the carrots, and the time and labor required for the operation of removing the remaining leaves hr after harvesting increase.

  In addition, when a plurality of ginsengs stay on the residual leaf processing conveyor 76, there is a problem that the ginsengs are more likely to come into contact with subsequent ginsengs, and the ginseng is damaged and the commercial value is easily reduced.

  In order to solve this problem, as shown in FIG. 23, the control device 200 is configured to increase or decrease the number of revolutions of the removing and conveying motor 620 in accordance with the interval calculated from the detection of the crop sensor 201. When the distance between the plants is narrower than the reference value, the number of rotations of the removing and conveying motor 620 is increased to increase the conveying speed of the residual leaf processing conveyor 76, thereby moving the ginseng quickly to the lower conveying side to reduce the residual leaf processing roller 75. , And can be sent to the sorting and conveying conveyor 87.

  Immediately after a narrower interval than the reference value is detected, an interval between the shares equal to or greater than the reference value may be detected. At this time, the rotation speed of the removal conveyance motor 620 is changed every time. Then, the transportation of the ginseng becomes unstable, and a load is applied to the components of the remaining leaf processing conveyor 76, so that the durability is reduced quickly. Therefore, once the rotation speed of the removal conveyance motor 620 increases, it is preferable that the process of reducing the rotation speed for a predetermined time (ridge: 30 seconds) is not performed. However, when a narrower inter-strain is detected and it is necessary to further increase the rotation speed of the removing and conveying motor 620, a process of increasing the rotation speed is performed.

  Accordingly, the ginseng can be prevented from staying on the remaining leaf processing conveyor 76, so that the ginseng that is cut off the foliage h and comes in contact with the ginseng can be prevented from being damaged, and a reduction in commercial value can be prevented.

  In addition, since the ginseng that moves to the sorting and conveying conveyor 87 without contacting the remaining leaf processing roller 75 can be reduced, the time and labor required for the operation of removing the remaining leaf hr after harvesting can be reduced.

  On the other hand, when the distance between the plants is wide, the number of rotations of the removing and conveying motor 620 is reduced to reduce the conveying speed of the remaining leaf processing conveyor 76, so that the ginseng is brought into contact with the remaining leaf processing roller 75 for a long time, and the remaining leaf hr is reliably reduced. Can be removed.

  Next, the sorting / conveying unit F will be described.

  As shown in FIGS. 1 to 6, a transmission shaft 120 for transmitting the driving force of the engine 7 penetrates through lower portions of the front and rear remaining leaf processing frames 72, 72, and protrudes toward the rear of the machine body. An output sprocket 121 is provided at the rear end of the motor 120. Further, an idle sprocket 122 is rotatably mounted above the output sprocket 121 of the remaining leaf processing frame 72 on the rear side of the fuselage. A recovery input shaft 123a for transmitting a driving force is rotatably mounted on 160, and an input sprocket 123 is provided on the recovery input shaft 123a.

  A driven sprocket 124 is rotatably mounted on the left and right sides of the fuselage (left side of the fuselage) with respect to the input sprocket 123 and the output sprocket 121, and extends over the output sprocket 121, the idle sprocket 122, the input sprocket 123, and the driven sprocket 124. The transmission chain 125 is wound endlessly. The driven sprocket 124 is provided on a remaining leaf processing output shaft 124a that supplies a rotational driving force to the second remaining leaf processing driving roller 73b.

  The idle sprocket 122 is provided between the output sprocket 121 and the input sprocket 123 so as to bend the transmission chain 125 from the vertical direction of the fuselage to the horizontal direction of the fuselage, and to pressurize the transmission chain 125 so as not to be loosened. is there.

  Further, a second input sprocket 126 is provided on the rotation shaft of the driven sprocket 124 between the rear leaf processing frame 72 and the driven sprocket 124, and the left and right sides of the airframe are lower than the second input sprocket 126. The counter sprocket 127 is rotatably arranged on the side. A second driven sprocket 128 is rotatably mounted on the left and right sides of the fuselage with respect to the counter sprocket 127 and the second driven sprocket 128 is rotatably mounted on the second input sprocket 126, the counter sprocket 127 and the second driven sprocket 128. The transmission chain 129 is wound endlessly. The counter sprocket 127 is provided on a sorting / conveying input shaft 127a that supplies a driving force to a sorting / conveying conveyor 87 described later.

  With the above configuration, the transmission path for supplying the driving force supplied from the engine 7 to the recovery conveyor 160, the remaining leaf processing conveyor 76, the remaining leaf processing roller 75, and the sorting / conveying conveyor 87 can be configured compactly. The front-rear width and the left-right width are suppressed, the turning property of the aircraft is improved, and the area required for storage is suppressed.

  Further, since the number of parts such as sprockets and transmission chains can be reduced, costs can be reduced.

  Then, as shown in FIGS. 3 to 6, the first transport frames 77, 77 are arranged in the front-rear direction on the body front side of the remaining leaf processing frame 72 on the body front side and below the shoulder aligning devices 54 </ b> L, 54 </ b> R. The first transport frames 77, 77 are arranged at predetermined intervals, and the front and rear second transport frames 78, 78 at the inner end of the first transport frames 77, 77 (ends on the other side of the fuselage, left and right) and at the outer side are spaced at predetermined intervals in the front-rear direction. In addition, the transport end portion is disposed so as to be vertically rotatable. The front and rear first transport frames 77, 77 are T-shaped when viewed from the front (rear), and have upper inclined portions on the other left and right sides that are inclined upward from the left and right central portions toward the other left and right sides. And

  Then, a collection driven roller 132b is rotatably mounted at the left and right end portions of the first transport frames 77 and 77 below the transport surface of the residual leaf processing conveyor 76, that is, below the upper surface of the residual leaf processing belt 74. The recovery input shaft 123a is driven by rotation of the recovery input shaft 123a to a position on the left and right sides of the machine relative to the recovery driven roller 132b and to a position attachable to the recovery input shaft 123a, specifically, to a position on one side of the machine left and right of the remaining leaf processing roller 75. The collection drive roller 132a to be used is disposed. Further, the collection belt 133 is wound endlessly over the collection driven roller 132b and the collection drive roller 132a to form the collection conveyor 160.

  The recovery conveyer 160 is disposed below the conveying path of the pull-out conveying device 24 and the shoulder aligning devices 54L and 54R, and receives the ginseng in which the foliage h is cut and falls on the upper side in the conveying direction than the foliage cutting device 61, It is transported from one side of the machine body to the other side, and is taken over by the sorting transport conveyor 87. For this reason, the collection driving roller 132a may be disposed below the collection driven roller 132b, and the collection conveyor 160 may be configured to be inclined downward from one side of the machine body to the other side.

  With the above configuration, even if the foliage h is cut and the ginseng falls during the transportation, the ginseng can move to the sorting and transporting conveyor 87 via the collection conveyor 160 and return to the original moving route. This eliminates the need for picking up and collecting ginseng that has fallen outside the transport path, thereby reducing the labor of the operator.

  In addition, by arranging the collection driven roller 132 below the conveying surface of the residual leaf processing conveyor 76, when a large amount of ginseng is supplied all at once, the ginseng does not hit the residual leaf processing roller 75 and the ginseng is located in front of the machine. Even under the condition of being extruded, the extruded ginseng can be moved to the collection conveyor 160 without stagnation, so that stagnation of the ginseng harvesting operation is prevented, and the work efficiency is improved.

  Furthermore, if the recovery conveyor 160 is inclined downward from the left and right sides of the fuselage to the other side, the ginseng received by the recovery conveyor 160 can roll by its own weight and move toward the sorting / conveying conveyor 87. Ginseng stays on the conveyor 160 and is prevented from coming into contact with the ginseng falling from above while being conveyed to the sorting and conveying conveyor 87 side, thereby preventing the ginseng from being damaged and improving the commercial value of the ginseng I do.

  Further, a pair of front and rear sorting drive sprockets 134, 134 provided on the sorting and transporting drive shaft 134a are disposed on the left and right sides of the machine body and below the collecting drive roller 133.

That is, the front and rear idle sprockets 135 and 135 rotate when receiving the driving force, but the rotation shaft 79 does not rotate.

  Further, a pair of front and rear selection driven sprockets 136 and 136 are rotatably mounted on the left and right other end portions of the front and rear second transport frames 78 and 78, and the front and rear selection driven sprockets 136 and 136 and the front and rear selection sprockets 136 and 136 are provided. The selection drive chains 137, 137 are wound endlessly over the selection drive sprockets 134, 134 and the front and rear idle sprockets 135, 135, respectively.

  Then, of the front and rear first transport frames 72, 72, the left and right sides of the machine body relative to the front and rear sorting drive sprockets 134, 134, that is, on the lower side in the transport direction of the selective transport conveyor 87, and the front and rear sorting drive sprockets 134, 134. The first front and rear first selection counter sprockets 139 and 139 that are outside the winding area of the front and rear selection transmission chains 137 and 137, that is, contact with the lower side of the body to prevent loosening, are provided below the body 134 with respect to the first body. It is mounted via the counter rotation shafts 139a, 139a.

  As shown in FIG. 6, the first selection counter sprockets 139, 139 are not connected to each other by a shaft or the like, and a space is formed between the front and rear of the first selection counter sprockets 139, 139. .

  Further, on the left and right sides of the machine body relative to the front and rear first sorting counter sprockets 139 and 139, that is, on the lower side in the transport direction of the sorting and carrying conveyor 87 and on the machine body above the front and rear first sorting counter sprockets 139 and 139, The second selection counter sprockets 140, 140 before and after the front and rear selection transmission chains 137, 137 are bent in contact with the winding area 18i of the front and rear selection transmission chains 137, 137 via the second counter rotation shafts 140a, 140a. And attach it.

  The second selection counter sprockets 140, 140 are not connected to each other, and a space is formed between the front and rear of the second selection counter sprockets 140, 140.

  Further, the third counter sprocket 141 before and after the front and rear idle transmission sprockets 135 and 135 and the outside of the winding area of the front and rear selection transmission chains 137 and 137 suppress the slack of the front and rear selection transmission chains 137 and 137. , 141 are mounted via third counter rotation shafts 141a, 141a.

  The front and rear second selection counter sprockets 140 and 140 are located at positions where they come into contact with the front and rear selection transmission chains 137 and 137 and outside the winding area of the front and rear selection transmission chains 137 and 137. First idle rollers 142, 142 before and after contacting and bending with 137, 137 are rotatably provided.

  Further, second idle rollers 143 and 143 for suppressing slack of the front and rear selection transmission chains 137 and 137 are rotatably provided on the other side of the body of the front and rear selection drive sprockets 134 and 134 and on the upper side of the body.

  Further, a plurality of transport bars 144 for placing and transporting ginseng are provided at equal intervals in the left-right direction, that is, at right and left intervals L1, between the front and rear of the front and rear sorting transmission chains 137, 137. Receiving bars 145... For preventing ginseng from rolling down on the upper inclined portion of the sorting and conveying conveyor 87 are arranged at predetermined intervals. Further, by providing the second transport frames 78, 78 with chain covers 146, 146 that cover the upper part of the sorting transmission chains 137, 137, the sorting transport conveyor 87 is configured.

  As shown in FIG. 3, between the transport start end of the sorting and transporting conveyor 87 and the transporting end of the collecting conveyor 160, there is a left and right space where ginseng can fall, and the transporting and leading end of the sorting and transporting conveyor 87. Is located below the transport end of the recovery conveyor 160, the carrots discharged from the transport end of the recovery conveyor 160 are transported by the transport conveyor 87 to the front and rear remaining leaf processing frames 72, 72. The takeover chute 147 to be moved to the start end is disposed in such a manner as to be inclined downward from the left and right sides of the body toward the left and right sides in rear view.

  The transfer chute 147 prevents the ginseng from being damaged even when it comes into contact with the ginseng, and also prevents the resistance from coming into contact with the transport bars 144 of the sorting and transporting conveyor 87, such as rubber or synthetic resin. When the ginseng is made of a soft member, the ginseng is prevented from being damaged, and the commercial value of the ginseng is maintained. In addition, the driving rotation of the sorting / conveying conveyor 87 is prevented from being disturbed, and the transportation of the ginseng is prevented, and the work efficiency is improved. .

  As described above, the sorting drive sprockets 134 and 134 are disposed on the other side of the machine body and on the lower side of the collecting drive roller 133, so that the transport start end of the sorting transport conveyor 87 is located below the transport end of the recovery conveyor 160. Can be configured so that the carrots that are transported are prevented from stagnating during handover, improving work efficiency, and the subsequent ginseng touches the stagnated ginseng, damaging the ginseng This prevents the commercial value from being reduced.

  In addition, since the sorting / conveying conveyor 87 is located below the remaining-leaf processing conveyor 76, stagnation of handover of ginseng from the remaining-leaf processing conveyor 76 to the sorting / conveying conveyor 87 is prevented, so that the work efficiency is further improved. Thus, a reduction in the commercial value of ginseng is prevented.

  Further, front and rear first sorting counter sprockets 139 and 139 and front and rear second sorting counter sprockets 140 and 140 are provided on the first counter rotating shaft 139a and the second counter rotating shaft 140a, and the front and rear rotating shafts 139a and 139a, Since the space is formed between the front and rear without connecting the 140a and 140a, there is no member to be caught when the stone moves to the front and rear space, so that the stone is easily removed and the sorting and conveying conveyor 87 is not damaged. Is prevented.

  By providing the first and second idle rollers 142 and 142 before and after contact with the sorting transmission chain 137 and the second idle rollers 143 and 143 before and after, the surface that does not convey ginseng, that is, the non-operating side, is pressed to separate the sorting transmission. Since the rotation of the chains 137, 137 stops or slows down, and the selection transmission chains 137, 137 can be prevented from being overloaded, which can be damaged, the amount of ginseng stored in the storage container 97 can be reduced. Even if the transport end portion side of the sorting and transporting conveyor 87 is turned up and down, the transport speed of the ginseng does not change, so that the work efficiency is improved and the ginseng sorting accuracy is improved.

  Further, by arranging the transport bars 144 in the left-right direction with a left-right space L1 therebetween, the sediment conveyed together with the carrot and the remaining leaves removed by the remaining-leaf processing roller 75 are sorted and conveyed from the left-right space L1. Since it can be dropped below 87, the amount of earth and sand and the remaining leaves that enter the storage container 97 is reduced, and the ginseng can be stored in the full capacity of the storage container 97. Thereby, the frequency of replacing the storage container 97 is reduced, and the work efficiency is improved.

  Further, by providing the receiving bars 145 at a wider interval than the transport bars 144, even if the ginseng rolls on the sorting / conveying conveyor 87, the receiving bars 145 stop the movement of the ginseng, so that the same ginseng is repeated several times. Is also prevented from returning to the transport start end, so that the work efficiency is improved, and the ginseng is prevented from being damaged by contact with the following ginseng when falling down, so that the commercial value of the ginseng is maintained.

  When the transport bar 144 is formed by winding a high-strength elastic body such as hard rubber or a soft elastic body such as soft rubber around the outer periphery of a bar-shaped metal, the carrots are collected from the collecting conveyor 160 and the remaining leaf processing conveyor 76. When taking over the ginseng, it is possible to prevent the ginseng from being damaged by the impact of the contact, thereby improving the commercial value of the ginseng.

  When the receiving bar 145 is configured such that rivets or bolts (not shown) are attached from the opposite side of the transport surface, that is, from below, and are attached to the sorting transmission chain 137, the rivet is attached to the winding area 18i of the sorting transmission chain 137. Since the bolts and bolts do not protrude, interference with other members is prevented, so that the sorting and conveying conveyor 87 is prevented from being damaged and rivets and bolts are prevented from being damaged by contact with the carrots being transported, The product value of ginseng is improved.

  A support plate 86 is attached between the left and right sides of the second transport frames 78, 78, and an elevating cylinder 88 for vertically moving the transport end portion of the sorting transport conveyor 87 between the support plate 86 and the machine frame 1 is extended and contracted. The sorting conveyor 87 is provided so as to be freely mounted to convey ginseng from one side of the machine body to the other side. Further, a discharge shooter 89 made of a soft member such as a rubber plate or a PVC plate is provided below the transport end portion of the sorting transport conveyor 87 to slide and move the ginseng discharged from the transport end portion of the sorting transport conveyor 87. Is mounted with its end hanging down.

  The elevating cylinder 88 may be of an electric type, a hydraulic type, or a pneumatic type, or may be of a type that is manually operated to expand and contract.

  In addition, at the rear part of the body frame 1 on the left and right sides of the body and on the rear side of the body with respect to the body of the sorting conveyor 87, an auxiliary operation for selecting the ginseng being transported by the sorting conveyor 87 and operating the sorting conveyor 87. The boarding step 90 on which a person rides is arranged, and the auxiliary work seat 91 is mounted on the boarding step 90 and at a position near the sorting idle sprockets 135 and 135 of the sorting and conveying conveyor 87.

  Further, an elevating operation pedal 92 for vertically moving the conveying end portion side of the sorting / conveying conveyor 87 by operating the elevating / lowering cylinder 88 vertically is arranged below the conveying path of the selecting / conveying conveyor 87.

  The sorting / transporting unit F is configured by arranging on the boarding step 90 and at a position where an auxiliary worker sitting on the auxiliary work seat 91 can operate by stepping on his / her feet.

  According to the above configuration, the lifting / lowering operation pedal 92 that operates the lifting / lowering cylinder 88 is provided at a position where the feet of the auxiliary worker seated on the auxiliary work seat 91 can reach, so that the auxiliary worker can remain seated on the auxiliary work seat 91. The transport end portion side of the sorting transport conveyor 87 can be moved up and down, so that the working efficiency is improved and the labor of the operator is reduced.

  Further, by providing the lifting operation pedal 92, the auxiliary operator can operate the vertical movement of the sorting and conveying conveyor 87 with only the feet, and the hand can be concentrated on the sorting work of the carrots being transferred, so that the sorting accuracy is improved. In addition, the hand can be prevented from being pinched or cut by the constituent members of the sorting and conveying conveyor 87, and the safety of work is improved.

  In the configuration of the sorting and transporting unit F, as described above, the sorting and transporting conveyor 87 transports the ginseng to the storage container 97 while discharging earth and sand and remaining leaves downward in the left and right spaces between the transport bars 144. It is.

  Chain covers 146 and 146 are provided above the sorting transmission chains 137 and 137 before and after driving the sorting and conveying conveyor 87, and earth and sand falling from above come into contact with the sorting transmission chains 137 and 137 before and after. Is preventing that.

  However, from the transporting end of the recovery conveyor 160, the earth and sand that has fallen from the carrots being transported by the pull-out transporter 24, and the soil that has adhered to the ginseng that has fallen due to the foliage h being cut off during the transport, In some cases, the dust is moved and discharged along the locus, and the earth and sand discharge position may be below the front and rear chain covers 146 and 146.

  Further, the remaining leaf processing roller 75 of the remaining leaf processing conveyor 76, after removing the remaining leaves of the carrot, changes the transport direction of the remaining leaf processing conveyor 76 so as to guide the ginseng near the transport start end of the sorting transport conveyor 87. The dirt that is mounted diagonally as a reference and falls directly below the end of the remaining leaf processing roller 75 bypasses the chain cover 146 and is located between the sorting drive sprocket 134 and the sorting transmission chain 137 on the rear side of the fuselage. May enter.

  When earth and sand, particularly hard stones, enter between the sorting drive sprocket 134 and the sorting drive chain 137, even if the stone is broken, the front and rear sorting drive chains 137 are lifted, and the timing at which the sorting drive sprocket 134 is not rotationally driven is reached. appear.

  When the sorting transmission chain 137 is lifted, the drive of the sorting and conveying conveyor 87 is temporarily stopped, and the ginseng being conveyed flows backward due to the reaction, and is damaged by contact with the following ginseng, thereby deteriorating the product value. Occurs.

  In addition, when a shift occurs in one of the sending-out timings of the front and rear sorting transmission chains 137, 137, a difference in the transport speed gradually starts before and after the sorting transport conveyor 87. The front and rear sorting transmission chains 137 and 137 are connected by a plurality of transport bars 144..., And the front and rear sorting drive sprockets 134 and 134 are mounted on a single sorting and transport drive shaft 134a. When the transport speeds of the transport bars are different, a load is applied to the transport bars 144... And the sorting transport drive shaft 134a.

  As a result, the transport bars 144 provided between the front and rear sorting transmission chains 137 and 137 and the sorting transport drive shaft 134a are distorted and do not rotate normally. Therefore, these parts must be replaced, and the operation is interrupted during that time. Therefore, there is a problem that the working efficiency is extremely lowered or the ginseng harvest time is missed.

  The sorting / conveying sprockets 134 and 134 before and after being provided on the sorting / conveying drive shaft 134a are provided with members that break preferentially when a load such as a shear pin is applied to prevent breakage of other members. Since it is necessary to replace at least the shear pin, the ginseng harvesting operation is interrupted during the replacement of parts, and the working efficiency is greatly reduced.

  In order to prevent this problem, front and rear guard covers 148 and 148 are provided on the upper and lower surfaces of the recovery belt 133 of the recovery conveyor 160 before and after the front and rear first transport frames 77 and 77, and the front one is directed toward the rear of the machine. Attach it in the rearward inclined position, and attach the rear one in the forward downward inclined position toward the front of the aircraft. One end of the front and rear guard covers 148, 148 faces above the transport start end of the collection conveyor 160, and the other end faces above the transport start end of the sorting and transport conveyor 87.

  More specifically, it extends to the left and right sides of the machine body beyond the front and rear sorting drive sprockets 134, 134 that constitute the sorting and conveying conveyor 87, the transport end portion of the collection conveyor 160, and the remaining leaf processing of the remaining leaf processing conveyor 76. The earth and sand discharged from the rollers 75 are guided by the front and rear guard covers 148 and 148 to positions on the left and right sides of the fuselage with respect to the sorting drive sprockets 134 and 134, and are dropped below the sorting and conveying conveyor 87. The sediment is prevented from being caught between the sorting transmission chains 137.

  With the above-described configuration, the sorting transmission chain 137 is lifted from the sorting drive sprocket 134, and a shift in the sending timing of the sorting transmission chain 137, that is, so-called misalignment is prevented, and a speed difference is generated at the front and rear positions of the sorting and conveying conveyor 87. This can prevent the transport bars 144... And the selective transport drive shaft 134a from being distorted and preventing the selective transport conveyor 87 from being driven.

  As a result, the ginseng harvesting work is not interrupted, the work efficiency is improved, and the ginseng can be harvested at a suitable time, thereby improving the commercial value of the ginseng. Further, there is no need to replace parts, and the labor of the operator is reduced.

  Further, the front and rear guard covers 148, 148 are inclined toward the center in the front-rear direction of the collection conveyor 160 and the sorting and conveying conveyor 87, respectively, so that the earth and sand placed on the guard covers 148, 148 can be separated by the collecting conveyor 160 and the sorting and conveying. Since it moves to the center of the conveyor 87 in the front-rear direction, the earth and sand moving from the conveyance end of the collection conveyor 160 to the conveyance start end of the selection conveyance conveyor 87 is prevented from approaching the front and rear selection driving sprockets 134, 134, Earth and sand are prevented from being caught between the selection drive sprocket 134 and the selection transmission chain 137.

  In addition, the earth and sand moving from the remaining leaf processing conveyor 76 to the sorting and conveying conveyor 87 also moves to the center in the front-rear direction of the sorting and conveying conveyor 87, so that the falling earth and sand is separated by the sorting driving sprocket 134 and the sorting transmission chain 137. Is prevented from being caught between the two.

  When the front and rear guard covers 148, 148 are inserted by inserting resin rivets into the front and rear first transport frames 77, 77, the guard covers 148 become worn, and the guard covers 148 need to be replaced. Since the guard cover 148 can be easily removed by pulling it up, the replacement work of the guard cover 148 can be easily performed, and the work efficiency is improved.

  In addition, the rear end of the front and rear guard covers 148, 148 in the conveyance direction, that is, the portion facing the conveyance start end of the sorting / conveying conveyor 87 is formed to be more flexible than other portions by making cuts or the like. Since it is possible to prevent the 148, 148 from becoming a resistance when coming into contact with the transport bars 144 and the receiving bars 145, an extra load is applied to the sorting and transporting conveyor 87, thereby preventing a decrease in durability.

  The front and rear guard covers 148 and 148 can prevent the earth and sand from dropping on the front and rear sorting drive sprockets 134 and 134 and the front and rear sorting transmission chains 137 and 137, and furthermore, can prevent the collection conveyor 160 and the sorting and conveying conveyor 87 from being front and rear. In order to easily guide the earth and sand toward the part, the thickness is set to about 60 to 90 mm. The guard cover 148 on the front side of the fuselage is less likely to allow earth and sand to enter than the guard cover 148 on the rear side, so the length is not necessary as in the above example, but if the front and rear sides have the same length, common parts can be used. Cost can be reduced.

  Next, the configuration of the storage section G will be described.

  As shown in FIGS. 2 and 7 to 11, the rotating shaft 93 is made to penetrate in the longitudinal direction of the machine body on the lower side (left and right side portions) of the second transport frames 78, 78 before and after the sorting transport conveyor 87 in the transport direction. The frictional resistors 94, 94 are provided on both front and rear ends of the rotating shaft 93 and outside the second transport frames 78, 78, respectively.

  As the frictional resistors 94, 94, any members having strong frictional resistance, such as disc springs, spring washers, and rubber rings, may be used.

  Also, the base sides of the front and rear hanger arms 95, 95 are provided at the front and rear ends of the rotation shaft 93 outside the frictional resistors 94, 94 in the front-rear direction, and the second transport frames 78, 78 and the hanger arms 95, 95 are provided. The hanger arms 95, 95 are configured to be able to move upward or downward only when a moving force greater than the resistance force is applied upward or downward due to the frictional resistance of the frictional resistors 94, 94 sandwiched between them.

  As shown in FIGS. 7, 9 and 10, the hanger arms 95, 95 have bent portions 95a, 95a at substantially central portions in the left-right direction, and extend from the bent portions 95a, 95a to the outer end of the body. If the shape is directed upward, that is, a shape bent in an inverted “H” shape in a front view or a rear view, even if the hanger arms 95, 95 rotate downward when the sorting and conveying conveyor 87 is raised. Even if the auxiliary worker no longer has a gap between the front and rear second transfer frames 78 and 78 and the hanger arms 95 and 95, and the auxiliary worker extends his arm toward the transfer end of the sorting and transfer conveyor 87, the second transfer is performed. Arms are not pinched between the frames 78, 78 and the hanger arms 95, 95, and the safety of the worker is improved.

  Further, since the hanger frames 95, 95 are located near the transport end side of the second transport frames 78, 78, the hanger frames 95, 95 are lower than the second transport frames 78, 78 at any inclination angle. , The sorting work space for the auxiliary worker is widened, so that the sorting accuracy is improved and the work efficiency is improved.

  A hanger frame 96 is attached to the ends of the hanger arms 95, 95 so as to protrude in the front-rear direction beyond the body front-rear end of the sorting / conveying conveyor 87 in the front-rear direction. A pair of front and rear hanging hangers 98, 98 for hanging and supporting a storage bag (flexible container bag) 97 at four points in the front, rear, left and right directions, are rotatably mounted in the left and right direction.

  Further, an upwardly inverted U-shaped (∩-shaped) outer hanging bodies 99a, 99a are welded to the outer ends of the hanging hangers 98, 98, respectively, and the inner ends of the hanging bodies are downwardly U-shaped. The hanging hooks 99f, 99f, 99f, 99f for welding the inner hanging bodies 99b, 99b of the mold and suspending the storage bag 97 on the outer hanging bodies 99a, 99a and the inner hanging bodies 99b, 99b are vertically movable. Attach to

  Instead of welding the outer suspensions 99a, 99a and the inner suspensions 99b, 99b, the outer ends of the suspension hangers 98, 98 are bent into an inverted U-shape (∩), and May be bent into a U-shape so that the hanging hooks 99f, 99f, 99f, 99f can be attached movably in the vertical direction.

  The hanging hangers 98, 98 are formed so that the four corners of the storage bag 97 are arranged in front and rear so that the upper opening of the storage bag 97 to be suspended is substantially square in plan view. Are suspended by the inner suspension bodies 99b, 99b.

  As shown in FIG. 10, the hanging hangers 98, 98 are removed from the hanger frame 96, the outer hanging members 99a, 99a are hooked on the front and rear ends of the hanger frame 96, and the inner hanging members 99b, 99b are attached. When the sorting conveyor 87 is rotated upward by being hooked on a support projection 119 provided at the outer end of the body of the collecting table 118 to be described later, the collecting table 118 is pulled up by the hanging hangers 98, 98 and automatically accommodated, that is, in the storage posture. Since the attitude of the collection frame 118 can be set to be substantially perpendicular to the body frame 1, it is not necessary to manually lift the collection table 118, and the labor of the operator is reduced.

  Further, when the sorting / conveying conveyor 87 is rotated to the upper limit to be in the housed state, the hanging hangers 98, 98 are in a posture orthogonal to the body frame 1, so that there are no members protruding outside the machine body frame 1 during storage. In addition, it is possible to prevent the protruding member from being damaged at the time of storage, and to prevent extra storage space.

  When lifting the collection table 118 with the hanging hangers 98, 98, the posture of the hanging hangers 98, 98 is a position rotated by about 180 degrees with respect to the posture of suspending the storage bag 97 in the open state.

  A lower limit regulation that receives the hanger arms 95, 95 forward and backward outside the transport end of the second transport frames 78, 78 and outside the fuselage with respect to the mounting position of the rotating shaft 93 to regulate downward rotation. The protrusions 100, 100 are attached. Further, an upper limit regulation for receiving the hanger arm 95 on the front side of the body at a position outside the second conveyance frame 78 on the front side of the body and above the lower limit regulating projection 100 on the front side of the body and closer to the rotation shaft 93 to restrict upward rotation. The projection 101 is attached.

  A hole (not shown) formed with a female screw is formed on the rear or front and rear sides of the body of the rotating shaft 93, and an adjustment knob 102 formed with a male screw (not shown) screwed into the hole is formed. By inserting and rotating the adjustment knob 102 to change the front-back distance between the second selection frames 78, 78 and the hanger arms 95, 95 sandwiching the frictional resistors 94, 94, the frictional resistance changes. Configuration.

  When the adjustment knob 102 is provided at the rear end of the rotating shaft 93 at the rear of the fuselage, it is easy for an auxiliary worker on the auxiliary work seat 91 to operate. This makes it easier for the worker who has performed the operation to adjust the frictional resistance of the frictional resistors 94, 94.

  Further, a slide shaft 103 that is slidable in the front-rear direction is provided below the second transport frame 78 on the transport end side of the sorting transport conveyor 87 with respect to the rotating shaft 93 and on the rear side of the machine body. A spring 104 for applying a biasing force in a forward direction of the fuselage is mounted. At the front end of the body of the spring 104, an auxiliary hook 105 is provided to suspend the front and rear middle part of the storage bag 97, which enters the lower part of the sorting / conveyor 87, inside the body to prevent loosening. At the end and outside the second frame 78, a slide knob 106 that allows the operator to slide the slide shaft 103 back and forth is attached.

  The slide knob 106 is provided with a hook lever 106a for facilitating manual operation of the slide knob 106 by a worker, and the hook lever 106a is provided at the base of the hook lever 106a toward the sorting / conveying conveyor 87 side, that is, toward the inside of the machine body. Attach the biasing torque spring 106b.

  The hook lever 106a contacts the inside of the body of the storage bag 97 during the harvesting operation to urge the inside of the body of the storage bag 97, so that it is possible to prevent the occurrence of slack inside the body of the storage bag 97. In addition, it is possible to prevent the ginseng from entering the slack and waste the storage amount, and it is not necessary to frequently replace the storage bag 97, thereby improving work efficiency. Further, when a tube made of a soft material such as rubber is attached to the surface of the hook lever 106a, the ginseng stored in the storage bag 97 can be prevented from contacting the hook lever 106a and being damaged. improves.

  In addition, since the visor plate 126 rotates together with the hanger frame 96 and is always in a substantially horizontal posture with the hanger hanger 98, 98, even if the sorting / conveying conveyor 87 is moved up and down, direct sunlight enters the storage bag 97. The ginseng is hard to penetrate, the ginseng is prevented from deteriorating, the commercial value can be improved, and the visor plate 126 is prevented from hindering the movement of the hanging hangers 98, 98.

  Further, the hook lever 106a is pressed against the bottom of the sorting / conveying conveyor 87 by the force of the torque spring 106b during non-operation (during storage), so that the hook lever 106a is prevented from protruding outside the machine body. At the time of storage, the hook lever 106a is prevented from being damaged due to contact, and no extra storage space is taken.

  If the slide shaft 103 is provided from the rear end of the machine of the sorting / conveying conveyor 87 to the middle of the front / rear portion or slightly to the front of the machine during non-operation, the position of the auxiliary hook 105 can be easily adjusted. Further, the slide shaft 103 may be provided from the front side to the rear side of the fuselage. In this case, an operator who gets on the control seat 11 can operate the slide shaft 103.

  Then, as shown in FIG. 11, a hanging strap hook 107 for hooking a hanging strap 97 i inside the body of the storage bag 97 on the lower side of the sorting and conveying conveyor 87 and on the upstream side of the rotating shaft 93 in the conveying direction of the sorting and conveying conveyor 87. Is attached, and a hanging band pin 108 for hooking a hanging band 97o on the outer side of the machine body is disposed above the hanger frame 96 so as to face the upper part of the machine body.

  The suspension bands 97i and 97o outside the inside of the machine are members for hanging the storage bag 97 containing ginseng by hooking it on a forklift or hoist.

  Next, the operation of the storage section G will be described.

  At the start of the ginseng harvesting operation, the sorting / conveying conveyor 87 is lowered to the lowest position in order to minimize the falling distance of the ginseng from the conveying end of the selecting / conveying conveyor 87 to the storage bag 97. Further, the four corners of the storage bag 97 are hooked on the hanging hooks 99f, 99f, 99f, 99f provided on the outer hanging bodies 99a, 99a of the front and rear hanging hangers 98, 98 and the inner hanging bodies 99b, 99b, respectively. The opening has a substantially square shape in plan view.

  Then, the front and rear hanger arms 95, 95 are rotated upward until they come into contact with the upper limit regulating projections 101, and the front and rear hanging hangers 98, 98 are inclined upward from the inside end of the body toward the outside end of the body. I do. Since the hanging hangers 98, 98 are inclined upward toward the outside of the machine, the suspended storage bags 97 are also inclined upward from the inside end of the machine toward the outside end of the machine. Posture.

  At this time, of the suspended storage bags 97, the inside of the machine from which the ginseng is discharged from the transport terminal end side of the sorting and transporting conveyor 87 is slackened, so that the vertical length is shortened. Length increases. It is assumed that the storage bag 97 is made of a flexible material such as a cloth material or a synthetic fiber.

  Further, the outer end of the discharge chute 89 is inserted into the inner end of the storage bag 97, and the inner end of the storage bag 97 is inserted below the transport end side of the sorting conveyor 87. The auxiliary hook 105 is hooked on a suspension hole (not shown) formed substantially at the center in the front-rear direction. Further, the hanging band 97i inside the body of the storage bag B is hooked on the hanging band hook 107, and the hanging band 97o on the outside of the body is hooked on the hanging band pin 108 on the hanger frame 96.

  The hanger arms 95, 95 are held in an inclined position set by the operator due to the frictional resistance of the frictional resistors 94, 94. If the hanger arms 95, 95 start rotating downward without permission, the adjustment knob 102 is rotated. Thus, the frictional resistance of the frictional resistors 94, 94 disposed between the second transport frames 78, 78 and the hanger arms 95, 95 is adjusted. When the adjustment knob 102 is rotated in the tightening direction, the contact area and the contact pressure of the frictional resistors 94, 94 increase to increase the frictional resistance, thereby preventing the hanger arms 95, 95 from moving without permission. In addition, when rotated in the loosening direction, the contact area and contact pressure of the frictional resistors 94, 94 decrease, and the frictional resistance decreases.

  When the harvesting operation proceeds and the ginseng stored in the storage bag 97 exceeds a certain amount, the auxiliary worker steps on the extension side of the elevating operation pedal 92 to extend the elevating cylinder 88 to move the sorting conveyor 87. Raise the transport end side.

  While the sorting / conveying conveyor 87 is moving up, the force of the hanger arms 95, 95 to descend exceeds the frictional resistance of the frictional resistors 96, 96, so that the hanger arms 95, 95 descend. The lowering of the hanger arms 95, 95 occurs only while the sorting and conveying conveyor 87 is being raised in order to secure a ginseng accommodating space in the accommodating bag 97.

  When the hanger arms 95, 95 rotate downward, the hanging hangers 98, 98 rotate about the hanger frame 96 as a fulcrum, and the outside of the hanging hanger 98.98 rotates downward, and the inside of the body also rotates. Rotate upward. Since the outside of the body of the storage bag 97 is located at the upper stage at the time of installation, there is almost no change in the position, but the inside of the body is pulled up by the movement of the hanging hangers 98, 98. Thereby, the slack that has occurred inside the body of the storage bag 97 is eliminated according to the amount of rise.

  It should be noted that there is almost no change in the drop between the transport end portion of the sorting transport conveyor 87 and the storage bag 97 due to this operation, and since the end of the discharge chute 89 hangs down into the storage bag 97, It does not protrude from 97.

  Further, every time the harvesting operation proceeds and the ginseng stored in the storage bag 97 exceeds a certain amount, the transport end of the sorting transport conveyor 87 is raised, the hanger arms 95 and 95 are rotated downward, and the storage bag 97 is rotated. The inside of the fuselage is lifted upward to secure a space for accommodating ginseng in the accommodation bag 97, and the ginseng leaning toward the inside of the fuselage is collapsed.

  Then, when the sorting / conveying conveyor 87 is rotated upward and the hanging hangers 98, 98 are in a substantially horizontal posture, the slack inside the body of the storage bag 97 is eliminated, and the vertical height between the inside and the outside of the body is substantially the same. Become. In this state, since about 200 kg of ginseng is stored in the storage bag 97, the worker stops traveling of the machine body and lowers the storage bag 97 outside the machine. At this time, the hanger arms 95 are configured to be in contact with the lower limit regulating protrusions 100.

  However, in the case where the ginseng in the field can be harvested within a few meters, if replacing the storage bag 97 requires a lot of trouble, the lid closing the upper opening of the storage bag 97 is hung and the hanger 98, 98 is hung. If the hooks are hooked on the outer hanging bodies 99a and 99a and the height of the storage bag 97 from the outside of the body to the vicinity of the center in the left-right direction is lengthened, ginseng of several meters (several kg) can be stored and stored. The work of replacing the bag 97 is omitted, and the work efficiency is improved.

  It should be noted that even in this state, there is almost no change in the head between the transport end portion of the sorting transport conveyor 87 and the storage bag 97.

  Then, when the storage amount of the storage bag 97 is full, the machine body, the pull-out / transport device 24, the sorting / conveying conveyor 87, etc. are stopped, the storage bag 97 is removed from the hanging hooks 99f, 99f, 99f, 99f, and the hook lever 106a is released. The user pulls the rear of the machine through the slide knob 106 to remove the auxiliary hook 105 from the storage bag 97. When the auxiliary hook 105 is released from the hook lever 106a by the urging force of the spring 104, the auxiliary hook 105 is automatically returned to the sorting / conveying conveyor 87 and the substantially central portion in the front-rear direction of the storage bag 97 when mounted.

  Further, by operating the operation handle 116 to lower the mounting table 112 forward or backward, the storage bag 97 storing the ginseng slides down the mounting table 112 by its own weight, so the storage bag 97 is lowered to the front side of the fuselage. At this time, the airframe is retracted, and when the storage bag 97 is lowered to the rear side of the airframe, the airframe is advanced, so that the storage bag 97 storing about 200 kg of ginseng is lowered from the storage section G and placed on the field.

  Then, when the harvesting operation is completed, the hanger arms 95, 95 are brought into contact with the upper limit regulating projection 101 again, and the sorting and conveying conveyor 87 is rotated upward to the uppermost position.

  With the above configuration and operation, since the outside of the body of the storage bag 97 is hardly loosened from the start of the work to the time of replacement, it is prevented that the ginseng enters the slack and the storage amount of the storage bag 97 is reduced, and The frequency of the bag 97 replacement is reduced, the work efficiency is replaced, and the labor of the operator is reduced.

  In the conventional mounting method of the storage bag, since the slack occurs on both sides of the inside and outside of the machine, ginseng enters into this slack, and even if the storage bag is lifted, the slack cannot be removed. The frequency was increasing.

  In addition, the slack that occurred in the storage bag was eliminated by moving the sorting conveyor up and down to secure the storage space, but every time the slack was removed, the operator had to operate the sorting conveyor, Had reduced efficiency. In particular, in the case of an auxiliary worker who performs sorting, the sorting accuracy during the operation is reduced.

  Since the drop between the transport end of the sorting and transport conveyor 87 and the left and right sides of the storage bag 97 is always substantially constant, it is possible to prevent the ginseng from being damaged by the impact of the fall, thereby improving the commercial value of the ginseng. I do.

  Further, the rotation of the hanger arms 95, 95 is normally restricted by the frictional resistors 96, 96, so that the hanger arms 95, 95 rotate downward only while the sorting / conveying conveyor 87 is raised. By operating the sorting / conveying conveyor 87 in accordance with the change in the amount of ginseng stored in the storage bag 97, the inside of the body of the hanging hangers 98, 98 can be moved upward in conjunction therewith. In addition, since the slack inside the body of the storage bag 97 is automatically eliminated, there is no need to move the sorting / conveying conveyor 87 up and down to remove the slack, and the work efficiency is significantly improved.

  Further, by providing the upper limit regulating projection 101 for determining the limit of the upper inclined posture of the hanger arms 95, 95 on the second transport frame 78 on the front side of the fuselage, the operator can easily understand the position for setting the hanger arms 98, 98, The positions of the hanger arms 95, 95 can be determined so that the storage bag 97 becomes full.

  In addition, since the upper limit regulating projection 101 is provided only on the second transport frame 78 on the front side of the machine body, the upper limit regulating projection 101 is within the working range of the auxiliary worker who sorts the ginseng being transported by the sorting transport conveyor 87. Since it does not exist, the auxiliary worker is prevented from hitting or getting caught in clothes during operation, and the burden on the worker is reduced.

  The lower limit regulating members 100, 100 are also provided on the second transport frame 78 on the rear side of the machine, but are provided at the inner ends of the hanging hangers 98, 98, and after the normal sorting operation. There is no problem because the area does not interfere with the operation of the auxiliary worker.

  In order to prevent the worker from forgetting to bring the hanger arms 95, 95 into contact with the upper-stage regulating projection 101, a precautionary note is written on the second transfer frame 78 on the rear side, so that forgetting the setting can be prevented.

  The outer hanging members 99a, 99a are provided at the outer ends of the hanging hangers 98, 98 so as to face upward, and the inner hanging members 99b, 99b are provided at the inner inner ends of the hanging hangers 98, 98. Since the lowering hooks 99f, 99f are located below the hanging hooks 99f, 99f on the outer side of the machine body, when the storing bag 97 is installed, the difference between the upper and lower heights of the storing bag 97 outside the machine body and the inside of the machine body increases. The ginseng is less likely to spill from the outside of the housing bag 97 to the body.

  In addition, when the left and right ends of the hanging hanger 98 are bent to form the outer hanging body 99a and the inner hanging body 99b, the hanging hanger 98 can be constituted by one bar, so that the cost can be reduced.

  Then, the hanging band 97i provided inside the body of the storage bag 97 is hooked on the hanging band hook 107 below the sorting / conveying conveyor 87, and the hanging band 97o provided outside the body is hooked on the hanging band pin 108 on the hanger frame 96. Accordingly, the hanging bands 97i and 97o pull the storage bag 97, so that slack generated in the storage bag 97 can be reduced.

  Further, by hooking the auxiliary hook 105 in a hole at a substantially central portion of the storage bag 97 in the front-rear direction, it is possible to reduce slack generated at a substantially central portion in the front-rear direction of the storage bag 97 on the inside of the fuselage. It is hard to get into the slack, and sufficient accommodation space can be secured.

  Then, when the slide knob 106 is pulled rearward of the fuselage, the slide shaft 103 slides rearward of the fuselage and the auxiliary hook 105 is disengaged from the storage bag 97. Therefore, the transport of the storage bag 97 filled with carrots and the sorting transport conveyor 87 is performed. Since the auxiliary hook 105 can be removed without having to enter the narrow space between the space below the terminal end portion, the work efficiency is improved and the labor of the operator is reduced.

  When the hanger arms 95 are brought into contact with the upper limit regulating projections 101 and the sorting and conveying conveyor 87 is rotated to the uppermost position, the hanging hangers 98 and 98 are rotated, and the outer ends of the hanging hangers 98 and 98 are machined. Since the portion is located inside the end of the body frame 1, the hanging hangers 98, 98 protruding from the body frame 1 do not hit against a wall or the like, and damage to the body is prevented.

  In addition, since the end of the discharge chute 89 is hung inside the storage bag 97, there is no space between the discharge chute 89 and the storage bag 97 where ginseng can fall. The ginseng can be prevented from falling, and the commercial value of the ginseng is improved. When the width of the discharge shooter 89 in the longitudinal direction of the machine is substantially the same as the width of the sorting / conveying conveyor 87 in the longitudinal direction of the machine, the above-described effect of preventing ginseng from falling is further improved.

  Next, the configuration of the loading / discharging section H will be described.

  As shown in FIGS. 2, 17 and 18, a loading / discharging frame 109 protruding to the outside of the fuselage is provided at the rear of the fuselage frame 1 on the left and right sides of the fuselage. A mounting table 110 is provided. The storage stage 110 rotates around the base on the front side of the fuselage, and when rotated downward, rotates until the rear side of the fuselage contacts the field scene, and when rotated upward, the storage stage 110 and the body frame 1 are rotated. They shall be arranged in a substantially horizontal posture.

  Then, a loading / discharging actuator 111 for rotating the holding / mounting table 110 is provided at the inner end of the loading / discharging frame 109, and an operation switch (not shown) for the loading / discharging actuator 111 is provided. The operation switch is provided on any one of the control panel 12, the second transport frame 78 on the side where the auxiliary work seat 91 is provided, or the inside end of the placing / discharging frame 109, or each.

  The housing mounting table 110 is provided with a front wall portion 110a for receiving the storage bag 97 on the front side of the fuselage, and left and right side walls 110b and 110b on the left and right sides of the fuselage, and a discharge space portion 110c for discharging the storage bag 97 on the rear side of the body. .
