Transplanter

  TECHNICAL FIELD The present invention relates to a root vegetable harvester that extracts a crop from a field and removes foliage during transportation to harvest the crop.

  A conventional root vegetable harvester conveys the crops that have been harvested from the field, regulates the upper conveyance of the crops by the shoulder aligning device to align the cutting positions of the foliage, and sandwiches the crops with a pair of left and right rotary blades to cut the crops. There is a technique in which, while dropping, the residual leaves remaining in the dropped crop are wound around the residual leaf processing roller while being conveyed by the residual leaf processing conveyor. (Patent Document 1) On one of the pair of left and right rotary blades described above, when cutting and dropping the foliage part, a disk made of a soft material is brought into contact with the shoulder part of the crop, and the side with the residual leaves of the crop remains. It is configured to be dropped in a posture facing the leaf processing roller, and the residual leaf cannot be contacted with the residual leaf processing roller, which reduces the work of manually removing the residual leaf.

  Also, if the position where the remaining leaves are dropped onto the conveyor is closer to the front side of the machine, the chances of contacting the remaining leaf removal roller with the remaining leaf removal roller (the time during which it can be contacted) will be reduced, so the residual leaves will remain. There is a problem that crops are transported as they are, and it is necessary to manually remove residual leaves.

  Further, since the conveying speed by the pulling and conveying device and the residual leaf processing conveyor is configured to be linked to the traveling speed, when the crops are harvested at the above-mentioned high speed, the front-back distance between the crops, when the so-called stock is narrow, the preceding crops are May fall on the residual leaf processing conveyor, and subsequent crops may fall before moving from the place and opening the drop space, the crops may be hit by scratches and the product value will decrease or the yield will decrease. There is a problem to do.

  In addition, the preceding crop whose residual leaves have been removed by the residual leaf processing roller prevents subsequent crops from approaching the residual leaf processing roller, and the crop is transported with the residual leaves left behind. There is a problem that it is necessary to perform work to remove residual leaves.

  It is an object of the present invention to solve the above problems and provide a root vegetable harvesting machine that can harvest and convey crops regardless of harvesting speed and that leaves less residue on the crops.

  The tension plates 53L, 53R are formed with elongated holes in the transmission cases 37, 37, and the mounting shafts 53a, 53a are attached to the end portions of the mounting shafts 53a, 53a for position adjustment by detachable members such as bolts. The bodies 53b and 53b are welded to each other.

  The tension plates 53L and 53R may be provided at positions substantially parallel to the left and right alignment devices 54L and 54R, but when the tension plate 52R is provided on the front side of the alignment device 53R on the outside of the machine body, the alignment plates on the inside of the machine body are aligned. The tension plate 52L of the device 53L is provided on the rear side of the machine body with respect to the tension plate 52R of the alignment device 53R, and when the large-diameter foliage portion h passes between the left and right of the alignment devices 54L and 54R, the tension plate 52L or tension Since the alignment chain 48 and the alignment guide body 52 move to the side where the plate 52R does not exist, even if the diameter of the foliage part h of carrot is large, it is possible to prevent the alignment devices 54L and 54R from being bitten and stop the machine body. It is not necessary to remove the foliage part h that has been bitten by doing so, and the work efficiency is improved.

  In addition, if the tension of the tension plates 53L and 53R is set to be weaker than the tension of the biasing springs 50 and 50, the alignment chains 48 and 48 will be appropriate when the large-diameter stems and leaves h pass and a load is applied. It can be bent to the position and retracted, can be prevented from being bitten by 54L and 54R, and it is not necessary to stop the machine body to remove the bited foliage portion h, thus improving work efficiency.

  Then, an elongated hole is formed in the transmission cases 37, 37 in the vicinity of the alignment drive sprockets 42, 42 and outside the alignment guide bodies 52, 52, and the surface of the alignment guide bodies 52, 52 is formed in this elongated hole. The left and right scrapers 55, 55 for dropping the scraps of the foliage h and mud attached to the are attached at the time of position adjustment along the trajectory of the alignment guide bodies 52, 52.

  By disposing the scrapers 55, 55 in the rearwardly inclined posture, the scraps of the foliage h and mud can be easily dropped downward.

  Then, the left and right cutting blade rotation shafts 56, 56 are provided at the rear positions of the shoulder aligning devices 54L, 54R of the left and right first gear units 38, 38, and the left and right bearings 57, 57 are attached to the cutting blade rotation shafts 56, 56. Attach freely. Then, the left and right support plates 59, 59 are attached to the left and right bearings 57, 57, and the left and right foliage cutting blades 60L, 60R are attached to the support plates 59, 59 to form a foliage cutting device 61.

  The left and right foliage cutting blades 60L and 60R are circular rotary blades, and the blade edges of the left and right shoulder aligning devices 54L and 54R overlap each other in the vicinity of the center of the left and right, and the foliage portion h of the carrot is removed. It is sandwiched and cut, and carrots are dropped. The carrot 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 more than the hairline of the carrot foliage h. This is a configuration in which the foliage portion h is cut on the upper side.

  Therefore, in the carrot that is cut off from the foliage portion h and falls, a so-called residual leaf hr is left uncut from the foliage portion h. This residual leaf hr needs to be removed before shipping, and after the harvesting operation, the operator needs to manually remove it using a kitchen knife or the like. By being provided, the residual leaf hr can be automatically removed during the harvesting operation.

  However, depending on the position at which the carrot falls to the residual leaf processing section E, there is not enough opportunity to come into contact with the residual leaf processing operation position when the carrot is conveyed by the residual leaf processing section E, and the residual leaf hr remains. It is sent from the residual leaf processing unit E to a post-process, and the worker needs to manually remove the residual leaf hr after harvesting, which requires extra labor and extra time for shipment preparation. There is a problem.

  In order to solve this problem, as shown in FIG. 14 (a) and FIG. 14 (b), of the left and right foliage cutting blades 60 </ b> L and 60 </ b> R that make up the foliage cutting device 61, they are placed outside the machine body (on the left and right side of the machine body). The left foliage cutting blade 60L provided is fixed in position. Then, the front end portion of the cutting transmission case 600 that transmits the driving force is fastened to the upper rear portion of the left shoulder aligning device 54L, and the left foliage cutting blade 60L is attached to the lower rear portion of the cutting transmission case 600. To do.

  In addition, inside the cutting transmission case 600, a drive sprocket 601 which receives a driving force from the left shoulder aligning device 54L, a driven sprocket 602 which rotates the left foliage cutting blade 60L, and the drive sprocket 601 and the driven sprocket 602. A transmission chain 603 that is wound and transmits the driving force is arranged.

  On the other hand, the foliage cutting blade 60R on the right side provided inside the machine body (on the other side of the machine body) is positionally adjusted in the machine longitudinal direction with respect to the foliage cutting blade 60L on the left side so that the cutting timing of the foliage part h can be changed. Wear via device 604. In addition, the front-back 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-right direction when moved the most forward, and the left foliage cutting blade 60L is moved even the most rearward. And is a range where a part of the area overlaps in a plan view.

  A base portion of the fixed side transmission case 605, which is positioned on the other side of the vehicle body from the rear upper portion of the right shoulder alignment device 54R toward the rear side, is provided, and the end portion of the fixed side transmission case 605 has an end portion on the upper side. A rotation-side transmission case 609 whose side faces the outside of the machine is rotatably attached. The right side foliage cutting blade 60R is attached to the lower part of the end 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 alignment device 54R, a fixed side output sprocket 607 that outputs the driving force, and the fixed side input sprocket 606 and the fixed side. A fixed-side transmission chain 608, which is wound around the output sprocket 607 and transmits the driving force, is arranged.

  In addition, 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, a rotation side output sprocket 611 that rotates the right foliage cutting blade 60R, A rotation-side transmission chain 612, which is wound around the rotation-side input sprocket 610 and the rotation-side output sprocket 611 and transmits the driving force, is arranged.

  A rack gear 613 that determines the rotation range of the rotation-side transmission case 609 is provided outside the rotation-side transmission case 609, and a rotation motor 615 including 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.

  It should be noted that a device having the same configuration as the moving device 604 may be provided on the outside of the machine body, that is, on the left foliage cutting blade 60L so that the front-back position can be adjusted, but if the position of either the left or right cutting blade is changed. Since the timing at which the foliage portion h is cut is changed, in the example of the present application, only the foliage cutting blade 60R on the inside (right side) of the machine body is configured to be adjustable in the front-rear position in order to suppress an increase in the number of parts and cost.

  Further, since a dust-proof cover for preventing the scattering of foreign matters such as soil and leaf debris is provided on the outside of the pulling and conveying device 24, 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 this example, only the foliage cutting blade 60R on the inside (right side) of the machine body is configured to be adjustable in the front-rear position.

  With the above configuration, when the moving device 604 is actuated to move the right foliage cutting blade 60R backward, the left and right foliage cutting blades 60L and 60R overlap each other, and the cutting action position for cutting the foliage portion h is moved to the rear side of the machine body. Can be changed.

  By moving the cutting position of the foliage h toward the rear of the machine when harvesting carrots at low speeds, the carrot that is cut off the foliage h and falls, is near the rear end of the machine of the residual leaf processing section E described later. That is, since the remaining leaf processing roller 75 can be dropped near the residual leaf processing start end portion, the residual leaf hr can be removed by using the substantially entire width of the residual leaf processing roller 75 in the front-rear direction. Therefore, the time and labor required for the work of removing the residual leaves hr from the carrot after harvesting can be reduced.

  Further, during high-speed work, etc., the front and rear positions of the left and right foliage cutting blades 60L, 60R are aligned, the cutting action position of the foliage part h is set to the front side of the machine body, and the fall of the carrot is accelerated, so that The width can be used to receive ginseng that falls.

  As a result, the ginseng that has fallen is transported toward the left and right sides of the aircraft while being scattered in the front-back direction, so it is easy to prevent the ginseng that precedes the falling position of the subsequent ginseng, and the ginseng bumps and is damaged. It prevents the merchandise value from decreasing.

  Further, since the fixed-side transmission case 605 and the rotation-side transmission case 609 which form the moving device 604 are arranged to avoid the conveyance paths of the pulling-out and conveying device 24 and the shoulder aligning devices 54L and 54R, they interfere with the conveyance of carrots. It prevents the carrot from being damaged and the commercial value from being reduced due to contact.

  Further, since the end portion side of the rotation side transmission case 609 is configured to rotate so as to swing forward and backward, the foliage cutting blade on the left side of the machine body is within the range in which the front and rear position of the foliage cutting blade 60R on the right side of the machine body can be adjusted. Since it is possible to suppress an increase or decrease in the overlapping area of 60L and the foliage cutting blade 60R on the right side of the machine body, it is possible to reliably cut the foliage portion h.

  Further, the left and right first output shafts 40, 40 are provided with left and right foliage conveying drive pulleys 62, 62, and the left and right foliage conveying is provided on the front side of the machine body with respect to the first left and right first gear units 38, 38 and above the shoulder alignment devices 54L, 54R. The driven pulleys 63, 63 are rotatably attached. The left and right foliage conveying drive pulleys 62, 62 and the left and right foliage conveying driven pulleys 63, 63 are wound endlessly with the left and right foliage conveying belts 64, 64, so that the foliage portion of the carrot from the pulling and conveying device 24. A leaf discharging and conveying device 65 that takes over h and discharges to the rear of the machine body is configured on the outer periphery of the upper portions of the left and right transmission cases 37, 37 and below the conveying end side of the pulling and conveying device 24.

  Further, left and right residual leaf transport drive pulleys 66, 66 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.

Then, the left and right residual leaf conveying belts 69, 69 are endlessly connected to the left and right residual leaf conveying drive pulleys 66, 66, the left and right residual leaf conveying driven pulleys 67, 67, and the left and right residual leaf conveying tension pulleys 68, 68. By winding, the residual leaf conveying device 70 that nips the upper part of the foliage and conveys it to the rear of the machine is formed above the leaf discharging conveying device 65.

  A foliage cutting section D is configured by providing a foliage shooter 71 that discharges the leaves that have been cut by the foliage cutting device 61 from the end portions of the above-described leaf discharge conveying device 65 and residual leaf conveying device 70 to the field.

  With the above configuration, the left and right alignment drive sprockets 42, 42 are arranged at positions separated from the left and right spacing portions of the shoulder alignment devices 54L, 54R through which the foliage portion h passes, thereby aligning the drive sprockets 42, 42 and Since it is possible to prevent the foliage portion h from being entangled with the second output shafts 41 and 41 and stopping the shoulder alignment devices 54L and 54R, the harvesting work is not interrupted and the work efficiency is improved.

  Further, by making the alignment drive sprockets 42, 42 smaller in diameter than the alignment driven sprockets 45, 45 and the alignment tension sprockets 47, 47, the alignment drive sprockets 42, 42 can be further moved to the left and right of the shoulder alignment devices 54L, 54R. Since it is separated from the spacing portion, the foliage portion h can be further prevented from being entangled with the alignment drive sprockets 42, 42 and the second output shafts 41, 41, and the work efficiency is further improved.

  Further, by providing the left and right biasing springs 50, 50 for biasing the alignment driven sprockets 45, 45, the left and right alignment chains 48, 48 when the foliage portion h comes into contact with the shoulder alignment devices 54L, 54R. The slack that occurs in the shoulders 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 handle the carrots even when the foliage portions h having different diameters pass continuously. The stems and leaves h can be received, the cutting positions of the stems and leaves h of carrot are properly aligned, the stems and leaves h are properly cut, and there is no need to remove the stems and leaves h in a later step, and the work efficiency is improved. ..

  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 difference in the diameter of the foliage h depending on the growth status and cultivar of ginseng, or the weather or Since the tension can be appropriately changed according to the work conditions such as soil quality, the foliage cutting position of ginseng can be properly aligned and the foliage part h can be reliably cut, so that the foliage remaining in the ginseng in a later step. There is no need to remove h, improving work efficiency.

  Further, the left and right alignment frames 43, 43 are formed with holes 44, 44 in the left-right direction of the machine body, and the rotation shafts 46, 46 provided with the alignment driven sprockets 45, 45 in the holes 44, 44 are movable. With the provision, the position-adjusted driven sprockets 45, 45 urged by the urging springs 50, 50 move closer to the conveying path of the foliage portion h in the state where no load is applied, so that the foliage portion h having a small diameter passes. At this time, the shoulder aligning devices 54L and 54R can receive the foliage portion h to properly align the cutting positions of the foliage portion h of the carrot, and it is not necessary to remove the foliage portion h remaining in the carrot in the subsequent process, improving the work efficiency. To do.

  Further, when a large load is applied to the left and right shoulder aligning devices 54L and 54R when the large-diameter foliage portion h passes, the alignment driven sprockets 45, 45 move along the hole portions 44, 44 along the movement path of the foliage portion h. Since it moves in the direction away from the shoulder aligning devices 54L and 54R, the front-to-left space between the shoulder aligning devices 54L and 54R can be prevented from being caught in the space between the shoulder aligning devices 54L and 54R, and the body can be stopped. It is not necessary to remove the bitten foliage portion h, and work efficiency is improved.

  In addition, when it is known before harvesting that the foliage h of the carrot has a large diameter, it is necessary to move the alignment driven sprockets 45, 45 away from the left and right of the left and right shoulder alignment devices 54L, 54R. By moving the shoulder aligning devices 54L and 54R to widen the left and right intervals on the upstream side in the transport direction, it is possible to prevent the shoulder aligning devices 54L and 54R from biting the foliage h, and removing the bited foliage h. No work is required and work efficiency is improved.

  Since the guide covers 51 are attached to each of the plurality of links 48a forming the alignment chains 48, 48 to form the alignment guide body 52, the guide cover 51 at any position can be freely attached and detached. Even if some of the guide covers 51 are damaged, just by replacing the guide covers 51 with new ones, the proper alignment performance is maintained and the foliage portion h is cut properly, so that the work efficiency is improved.

  Further, since it is not necessary to replace the entire alignment guide body 52, the cost can be reduced.

  Further, since the guide cover 51 can be attached and detached manually without using a tool, the replacement work can be easily performed.

  Since the guide cover 51 has a U-shape when viewed from the front, covering the contact surfaces of the top and bottom surfaces of the alignment chain 48 and the foliage portion h, a space is provided between the guide cover 51 and the alignment chain 48. Since it does not occur, it is possible to prevent the stem and leaf part h from being sandwiched between the guide cover 51 and the alignment chain 48, and the carrot cannot be aligned at an appropriate cutting position, and the stem and leaf part h is left uncut. The work for removing the part h is not required, the work efficiency is improved, and the root part of the carrot can be prevented from being cut, and the commercial value of the carrot is improved.

  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 and the like in an arcuate trajectory, 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 part h of carrot can be properly aligned by receiving the foliage part h, and it is not necessary to remove the foliage part h remaining in the carrot in the subsequent process, improving the work efficiency. To 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 and the like in an arcuate path, the guide covers 51, ... Since the protruding portion 51c covers the space formed between the front and back, the foliage h is caught in the space between the front and back of the guide covers 51 ..., and the carrots are not aligned at the proper cutting position and the foliage h is cut. It can be prevented from being left behind, the work of removing the foliage part h in a later step is not required, the work efficiency can be improved, and the root part of the ginseng can be prevented from being cut, and the commercial value of the ginseng can be improved.

  Since the left and right tension plates 53L and 53R are provided in the winding area 18i of the alignment chains 48, 48, the alignment chains 48, 48 are pressed from the winding area 18i, so that the large-diameter stems and leaves h When passing, since the alignment chains 48, 48 of the portions which are not pressed by the tension plate 53L or the tension plate 53R can be retracted toward the alignment drive sprockets 42, 42, the foliage portion h of the shoulder alignment devices 54L, 54R is removed. There is no need to be bitten between the left and right, and it is not necessary to stop the machine and remove the bited foliage portion h, thus improving work efficiency.

  Further, by providing the left and right scrapers 55, 55 for scraping off debris such as debris and mud attached to the alignment guide bodies 52, 52 that move on the outer periphery of the alignment drive sprockets 42, 42, Since it is possible to remove the foreign matters adhering to the alignment guide bodies 52, 52 at a position apart from the movement path of the foliage part h, it is possible to prevent debris of the foliage part h from being entangled with each part of the shoulder alignment devices 54L, 54R. Therefore, it is not necessary to stop the machine body and remove the shards of the entangled foliage portion h, and the work efficiency is improved, and the lump of mud is prevented from damaging the root part of the ginseng, and the commercial value of the ginseng is improved.

  Further, since the mounting positions of the scrapers 55, 55 can be changed along the long holes, the scrapers 55, 55 are set at optimum positions according to the average diameter of the stems and leaves h of the carrots in the field where the harvesting work is performed. However, by reliably removing the debris of the foliage h and foreign matters such as mud from the alignment guide body 52 and the office work 52, the above effect is further improved.

  Then, the leaf-shooting shooter 71, which discharges the leaves (cut off foliage portion h) cut from the ginseng by the foliage cutting device 61 to the field, discharges the foliage to the already dug side (the side where the ginseng has been harvested). Since it is installed in the downward inclined posture, the discharged leaves fall onto the carrots on the undigged side (the side where the carrots are not harvested), and the discharged leaves are sandwiched between the left and right conveyance belts 19 and 19 and left and right. Since it is possible to prevent the harvesting part C from being entangled with the driven pulleys 17 and 17 and stopping the harvesting part C so as to prevent the harvesting work from being improved, the work efficiency is improved and the leaves that have fallen onto the ginseng hinder the visibility of the ginseng to be harvested. Can be prevented.

  In addition, in order to prevent the foliage portion h conveyed by the residual leaf conveying device 70 from lying down in the lateral direction of the machine body and preventing the foliage portion h from being conveyed to the rear of the machine body, the remaining cases are conveyed to the transmission cases 37, 37. Leaf discharge receiving plates 177 having substantially the same length as the front-rear direction of the apparatus 70 are provided on the left and right sides. Due to the existence of the leaf receiving plate 177, the leaf receiving plate 177 receives the foliage portion h when the foliage portion h being conveyed falls down, so that the foliage portion h is conveyed to the conveyance end portion by the residual leaf conveying device 70. , And is discharged to the field through the leaf shooter 71.

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

  As shown in FIG. 1 to FIG. 6, front and rear residual leaf processing frames 72, 72 are provided below the foliage cutting device 61, and a first roller 73a is provided between the residual leaf processing frames 72, 72 on the left and right sides of the machine body. Rotatably attached. Further, a second roller 73b is rotatably mounted between the front and rear of the left and right sides of the body of the residual leaf processing frames 72, 72 and below the first residual leaf processing roller 73a.

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

  Further, the remaining leaf processing section E is configured by providing a removing / conveying motor 620 for rotating the second roller 73 on the rear side of the machine body of the remaining leaf processing conveyor 76. The removal / conveyance motor 620 is a variable rotation motor whose rotation speed is changeable.

  The residual leaf processing conveyor 76 is tilted from one side of the machine body to the other side of the machine body by about 2 to 5 degrees.

  Further, the front end portion of the residual leaf processing conveyer 76 is located at substantially the same position as the front end portions of the left and right foliage cutting blades 61L and 61R, or slightly forward of the front end portions of the left and right foliage cutting blades 61L and 61R. The rear end portions are located on the rear side of the machine body relative to the rear body side of the left and right forage cutting blades 61L and 61R.

  As a result, when harvesting is performed at a high vehicle speed, or when there are many irregularities in the field and the machine easily shakes, even if the carrots with the foliage h cut inertially fall to the rear of the machine, the residual leaf processing conveyor Since it 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, and the work efficiency is improved.

  Furthermore, since the ginseng does not easily fall onto the machine body, the ginseng is prevented from being damaged by the fall, and the reduction in the commercial value is reduced.

  When the carrots fall on the front side of the machine rather than the front end of the residual leaf processing conveyor 76, the ginseng falls on the sorting and conveying section F, so that it is necessary to remove the residual leaves hr after harvesting, but it does not come off from the conveying route. Therefore, the work efficiency does not easily decrease.

  Further, since the carrot that has fallen moves due to the drive of the residual leaf processing belt 74 and the movement due to the inclination, the movement of the carrot does not stop on the residual leaf processing conveyor 76, and it is not necessary to manually move the stopped carrot. , Work efficiency is improved. In addition, since the residual leaf processing conveyor 76 is slightly inclined (about 2 to 5 degrees), the residual leaf processing conveyor 76 is inclined with respect to the ground even if the aircraft is tilted to the left or right side of the vehicle due to the state of the field or the like. Since the ginseng stays in a substantially horizontal state, the ginseng does not stay on the residual leaf processing conveyor 76 or move in the direction opposite to the conveying direction of the residual leaf processing conveyor 76. There is no need to return it, and work efficiency improves.

  With the above configuration, the residual leaf treatment roller 75 that constitutes the residual leaf treatment conveyer 76 cuts off the residual leaves of the carrot that have been left uncut by the foliage cutting device 61, so that the operation of manually cutting the residual leaves after the harvesting work is omitted. The work efficiency can be improved.

  In addition, since the residual leaf treatment belt 74 constituting the residual leaf treatment conveyor 76 is made of an elastic material such as rubber or urethane, the residual leaf treatment is performed even if the foliage portion h is cut off by the foliage cutting device 61 and carrots fall. 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.

  Using the pulling and conveying section C, the foliage cutting section D, and the residual leaf processing section E having the above-mentioned configuration, a control configuration that more reliably cuts the foliage section h and removes the residual leaf hr in accordance with the traveling speed and the carrot harvesting pace. 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 potentiometer 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 in the normal direction or the reverse direction in accordance with the increase / decrease of the traveling speed and the amount of increase / decrease, and the right foliage cutting blade 60R is moved to the front-back position suitable for the traveling speed.

  As a result, when the traveling speed becomes faster, 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 carrots that fall can be received by utilizing the front-back width on the residual leaf processing conveyor 76. It is possible to prevent the ginseng from coming off the route and the subsequent ginseng from contacting and damaging the preceding ginseng that has accumulated due to the removal of the residual leaves hr.

  Further, when the traveling speed becomes slower, the cutting position of the foliage portion h by the foliage cutting device 61 becomes closer to the rear side of the machine body, so that the residual leaf hr can be removed using substantially the entire front-back width of the residual leaf treatment roller 75. As a result, the residual leaves hr hardly remain in the carrot, and the time and labor required for the removal work after harvesting are reduced.

  The front-rear position of the right foliage cutting blade 60R may be changed in conjunction with the operation position of the traveling operation lever 13 detected by the lever potentiometer 13a. At this time, if the cutting potentiometer 616 for detecting the turning angle of the turning side transmission case 609 is provided and the turning motor 615 is stopped by the detection of the cutting potentiometer 616, the right foliage cutting blade 60R is set to the traveling speed. It is stopped at the 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. However, the traveling speed is calculated from the distance between two GPS points at a predetermined time, or the left and right drives for transmitting the left and right crawlers 6L and 6R. A method in which the rotation speed of the shafts 9, 9 is detected by a rotation sensor or the like to calculate the traveling speed may be used.

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

  Further, although the above is the control configuration by the control device 200, the vicinity of the base portion of the travel 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 travel operation lever 13 is adjusted. In addition, the front and rear position of the right foliage cutting blade 60R may be changed.

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

  Alternatively, instead of the traveling speed, the front and rear positions of the right foliage cutting blade 60R may be moved back and forth based on the distance between the ginseng plants by the left and right crop sensors 201.

  As shown in FIG. 22, when the ginseng strains are wide, the foliage part h of the subsequent ginseng is cut off when the preceding ginseng is moving to the removal action area of the residual leaf hr. It is assumed that the cutting blade 60R is moved to the rear side of the machine body to reliably remove the remaining leaves hr of the subsequent carrot with the entire width in front of and behind the residual leaf processing roller 75.

  On the other hand, when the distance between the plants is narrow, the cutting interval of the foliage part h of the front and rear ginseng is short, and the subsequent ginseng easily collides with the preceding ginseng, so to cut the foliage part h as soon as possible, the right foliage cutting blade 60R is moved to the front side of the machine to prevent carrots from being damaged by contact with each other.

  Further, when the distance between the plants detected by the crop sensor 201 is narrow, a plurality of carrots will be on the residual leaf processing conveyor 76. When a plurality of carrots are in contact with the residual leaf processing roller 75, the succeeding carrots are brought into contact with the preceding carrot and conveyed together, and the residual carrots are sent to the sorting / conveying conveyor 87 described later without being processed. Therefore, the residual leaf hr is likely to remain in the carrot, and there is a problem that the time and labor required for removing the residual leaf hr after harvesting increases.

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

  In order to solve this problem, as shown in FIG. 23, the control device 200 is configured to increase or decrease the rotation speed of the removal conveyance motor 620 according to the stock calculated from the detection of the crop sensor 201. When the distance between the plants is narrower than the reference value, the number of revolutions of the removing and conveying motor 620 is increased to increase the conveying speed of the residual leaf processing conveyor 76, so that the carrots are quickly conveyed to the lower side of the conveyance and the residual leaf processing roller 75. Can be sent to the sorting and conveying conveyor 87.

  It is conceivable that a stock interval that is equal to or greater than the reference value is detected immediately after the stock interval that is narrower than the reference value is detected. At this time, the rotation speed of the removal conveyance motor 620 is changed every time. As a result, the transportation of carrots becomes unstable and a load is applied to the components of the residual leaf processing conveyor 76, so that the durability is rapidly reduced. Therefore, it is preferable that the processing for lowering the rotation speed for a predetermined time (ridge: 30 seconds) is not performed once the rotation speed of the removal conveyance motor 620 increases. However, when a narrower distance between stocks is detected and it is necessary to further increase the rotation speed of the removal and conveyance motor 620, processing for increasing the rotation speed is performed.

  As a result, carrots can be prevented from staying on the residual leaf processing conveyor 76, so that carrots that are cut and fallen from the foliage h can be prevented from coming into contact and being damaged, and a decrease in commercial value is prevented.

  Further, since it is possible to reduce the ginseng that moves to the sorting and conveying conveyor 87 without contacting the residual leaf processing roller 75, the time and labor required for the work of removing the residual leaf hr after harvesting can be reduced.

  On the other hand, when the distance between the plants is wide, the carrot is kept in contact with the residual leaf processing roller 75 for a long time by decreasing the rotation speed of the removal / conveyance motor 620 and slowing the transportation speed of the residual leaf processing conveyor 76, and the residual leaf hr is surely removed. It can be removed.

  Next, the sorting and conveying section F will be described.

  As shown in FIGS. 1 to 6, the transmission shaft 120 that transmits the driving force of the engine 7 penetrates through the lower portions of the front and rear residual leaf treatment frames 72, 72 and projects toward the rear side of the machine body.

The recovery driving roller 132a is arranged. Further, the recovery belt 133 is endlessly wound around the recovery driven roller 132b and the recovery drive roller 132a to form the recovery conveyor 160.

  The recovery conveyor 160 is disposed below the transport path of the pull-out transport device 24 and the shoulder aligning devices 54L and 54R, and receives a carrot that is cut and falls at the foliage portion h on the transport direction upper side than the foliage cutting device 61, It is to be conveyed from one side of the machine body to the other side and taken over by the sorting conveyer 87. Therefore, the recovery driving roller 132a may be disposed below the recovery driven roller 132b, and the recovery conveyor 160 may be configured in a downward inclined posture from one side of the machine body to the other side thereof.

  With the above configuration, even if the foliage portion h is cut and carrots may fall during transportation, the carrots can move to the sorting and conveying conveyor 87 via the recovery conveyor 160 and return to the original movement route. The work of collecting the carrots that fall outside the transportation route is unnecessary, and the labor of the worker is reduced.

  Further, by disposing the recovery driven roller 132 below the conveying surface of the residual leaf processing conveyor 76, when a large amount of carrots are supplied all at once, the carrots do not come into contact with the residual leaf processing rollers 75 and the carrots are placed on the front side of the machine. Even if the carrot is pushed out, the carrot that has been pushed out can be moved to the collection conveyor 160 without being stagnant, so that the carrot harvesting work is prevented from being stagnant and the work efficiency is improved.

  Further, when the collecting conveyor 160 is tilted downward from one side of the machine body to the other side of the right and left, the carrots received by the collecting conveyor 160 can be rolled by their own weight and moved toward the sorting and conveying conveyor 87. Since carrots are prevented from staying on the conveyor 160 and coming into contact with the carrots falling from above while being conveyed to the sorting and conveying conveyor 87 side, the carrots are prevented from being damaged and the commercial value of carrots is improved. To do.

First idle rollers 142, 142 are provided rotatably before and after they come into contact with 137, 137 and bend.

  Further, second idle rollers 143, 143 for restraining the slack of the front and rear sorting transmission chains 137, 137 are rotatably provided on the left and right sides of the body of the front and rear sorting drive sprockets 134, 134 and on the upper side of the body.

  Further, a plurality of carrying bars 144 for carrying and carrying carrots are provided at equal intervals in the left-right direction, that is, left and right intervals L1 are provided between the front and rear of the front and rear sorting transmission chains 137, 137. Receiving bars 145, which prevent carrots from rolling down at the upper inclined portion of the sorting and conveying conveyor 87, are arranged at predetermined intervals for each plurality. Further, by providing the second transfer frames 78, 78 with chain covers 146, 146 that cover the upper portions of the selection transmission chains 137, 137, a selection transfer conveyor 87 is configured.

  As shown in FIG. 3, a left and right space where carrots can fall is provided between the transport start end of the sorting and transporting conveyor 87 and the transport end of the collecting conveyer 160, and the transporting start end of the sorting and transporting conveyor 87 is provided. Is located below the transfer end of the recovery conveyor 160, the carrots discharged from the transfer end of the recovery conveyor 160 are transferred to the front and rear residual leaf processing frames 72 and 72 by the selection transfer conveyor 87. The takeover shooter 147 to be moved to the starting end portion is arranged in a posture inclining downward from one left and right sides of the machine body toward the other left and right sides in rear view.

  The takeover shooter 147 prevents damage to the carrot even if it comes into contact with the carrot, and also prevents contact with the transport bar 144 of the sorting and transporting conveyor 87 from causing resistance. When the soft member is used, carrots are prevented from being damaged and the commercial value of ginseng is maintained, and the carrot is prevented from being delayed due to disturbed driving rotation of the sorting / conveying conveyor 87, thus improving work efficiency. ..

  As described above, by disposing the sorting drive sprockets 134, 134 on the left and right sides of the machine body and on the lower side of the collection driving roller 133, the transport start end of the sorting transport conveyor 87 is located below the transport terminal end of the recovery conveyor 160. Since the part can be located, the transported carrots are prevented from stagnation when handing over and the work efficiency is improved, and the stagnate ginseng is contacted by the succeeding ginseng and the ginseng is damaged. This prevents the product value from decreasing.

  Further, since the sorting / transporting conveyor 87 is located below the residual leaf processing conveyor 76, stagnation of the transfer of carrots from the residual leaf processing conveyor 76 to the sorting / transporting conveyor 87 is prevented, and the work efficiency is further improved. , The reduction of the product value of carrot is prevented.

  Further, the front and rear first sorting counter sprockets 139, 139 and the front and rear second sorting counter sprockets 140, 140 are provided on the first counter rotation shaft 139a and the second counter rotation shaft 140a, and the front and rear rotation shafts 139a, 139a, Since 140a and 140a are not connected to each other and a space portion is formed between the front and rear, a member that is caught when a stone moves to the front and rear space portion is eliminated, so that stones are easily removed and the sorting and conveying conveyor 87 is damaged. To be prevented.

  By providing the front and rear first idle rollers 142, 142 and the front and rear second idle rollers 143, 143 that come into contact with the selection transmission chain 137, the surface not carrying carrots, that is, the non-acting side is compressed and the selection transmission is performed. Since it is possible to prevent the chains 137 and 137 from slackening such that the rotation stops or slows down and the occurrence of overload that may damage the sorting transmission chains 137 and 137, it is possible to adjust the amount of the ginseng stored in the storage container 97. Even if the transporting end portion side of the sorting and transporting conveyor 87 is rotated up and down, the transporting speed of the carrot is not changed, so that the work efficiency is improved and the sorting accuracy of the carrot is improved.

  Further, by arranging the transport bars 144 in the left-right direction at a left-right interval L1, the earth and sand carried together with the carrot and the residual leaves removed by the residual-leaf processing roller 75 are sorted and conveyed from the left-right interval L1. Since it can be dropped below 87, the amount of earth and sand and residual leaves that enter the container 97 can be reduced, and carrots can be stored in the container 97 at the full capacity. As a result, the frequency with which the storage container 97 is replaced is reduced, and the work efficiency is improved.

  Further, by providing the receiving bars 145 at a wider interval than the carrying bar 144, even if the carrots roll on the sorting and conveying conveyor 87, the receiving bars 145 ... stop the movement of the carrots, so that the same carrots can be fed many times. Since it is prevented from returning to the starting end portion of the carrier, the work efficiency is improved, and the carrot is prevented from coming into contact with and damaging subsequent carrots, thereby maintaining the commercial value of the carrot.

  In addition, when the transport bar 144 is configured by wrapping a high-strength elastic body such as hard rubber or a soft elastic body such as soft rubber around the outer peripheral portion of a rod-shaped metal, the ginseng from the recovery conveyor 160 or the residual leaf processing conveyor 76 can be used. Since it is possible to prevent carrots from being damaged by the impact of contact when taking over, the product value of carrots is improved.

  Further, if the receiving bar 145 is configured to be attached to the selection transmission chain 137 by mounting a rivet or a bolt (not shown) from the opposite side of the conveying surface, that is, from the lower side, it is riveted in the winding area 18i of the selection transmission chain 137. Since the bolts and bolts do not project, interference with other members is prevented, damage to the sorting and conveying conveyor 87 is prevented, and rivets and bolts are prevented from coming into contact with carrots being conveyed, The product value of carrots is improved.

  Then, a support plate 86 is attached between the right and left sides of the second transfer frames 78, 78, and an elevating cylinder 88 for vertically moving the transfer end side of the sorting transfer conveyor 87 is extended between the support plate 86 and the machine body frame 1. A sorting / conveying conveyor 87 that freely attaches and conveys carrots from one side of the machine body to the other side of the machine body is configured. Further, a discharge shooter 89 composed of a soft member such as a rubber plate or a vinyl chloride plate that slides and moves the carrot discharged from the transport end portion of the sorting and transporting conveyor 87 to the lower portion of the transporting end portion of the sorting and transporting conveyor 87. Install with the end hanging downwards.

  The lifting cylinder 88 may be of an electric type, a hydraulic type, a pneumatic type, or may be manually extended and contracted.

  Further, at the rear of the left and right sides of the body frame 1 on the other side of the machine body and on the rear side of the machine body than the sorting and conveying conveyor 87, an auxiliary work for sorting carrots being transported by the sorting and transporting conveyor 87 and operating the sorting and transporting conveyor 87. A boarding step 90 for a person to board is arranged, and an auxiliary work seat 91 is attached on the boarding step 90 and at a position near the selection idle sprockets 135, 135 of the selection conveyor 87.

  Further, an elevating operation pedal 92 for moving the elevating cylinder 88 up and down to vertically move the conveying end portion side of the selecting and conveying conveyor 87 is arranged below the conveying path of the selecting and conveying conveyor 87.

  Then, the sorting and conveying section F is configured by arranging it on the boarding step 90 and at a position where an auxiliary worker seated on the auxiliary work seat 91 can step on and operate with his / her foot.

  According to the above configuration, since the lifting operation pedal 92 for operating the lifting cylinder 88 is provided at a position where the foot of the auxiliary worker seated on the auxiliary work seat 91 can reach, the auxiliary worker remains seated on the auxiliary work seat 91. The transfer end portion side of the sorting transfer conveyor 87 can be moved up and down, which improves the work efficiency and reduces the labor of the operator.

  Further, by providing the lifting operation pedal 92, the auxiliary worker can operate the vertical movement of the sorting and conveying conveyor 87 only with his / her feet, and the hands can be concentrated on the sorting work of the carrots being transported, so that the sorting accuracy is improved. In addition to being improved, it is possible to prevent the hands from being sandwiched or cut by the constituent members of the sorting and conveying conveyor 87, and the work safety is improved.

  In the above configuration of the sorting and transporting section F, as described above, the sorting and transporting conveyor 87 transports carrots to the storage container 97 while discharging the earth and sand and the residual leaves downward in the left and right spaces between the transporting bars 144. Is.

  Chain covers 146 and 146 are provided above the sorting transmission chains 137 and 137 before and after driving the sorting / transporting conveyor 87, respectively, and the falling and contacting sorting transmission chains 137 and 137 come in contact with earth and sand falling from above. To prevent that.

  However, from the end of the conveyor of the recovery conveyor 160, the earth and sand falling from the carrot being conveyed by the pulling and conveying device 24, and the earth and sand adhering to the carrot that has fallen due to the foliage h being cut off during conveyance, There is a case where it is moved and discharged along the path of falling in, and the discharge position of the earth and sand is below the front and rear chain covers 146 and 146.

  In addition, the residual leaf treatment roller 75 of the residual leaf treatment conveyor 76 removes the residual leaves of the carrot and then guides the carrot to the vicinity of the transport start end portion of the sorting and transporting conveyor 87 in the transport direction of the residual leaf processing conveyor 76. The slantingly mounted as a reference, the earth and sand falling directly from the end of the residual 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 machine body. It can get in.

  If earth and sand, especially hard stones, enter between the sorting drive sprocket 134 and the sorting transmission chain 137, even if the stones are broken, the sorting transmission chain 137 at the front and the rear floats up, and there is a timing at which the sorting drive sprocket 134 is not rotated. Occur.

  When the sorting transmission chain 137 is lifted up, the driving of the sorting and conveying conveyor 87 is temporarily stopped, and the carrot being transported flows backward due to the reaction, and the carrots that come in contact with the succeeding carrots are damaged and the product value is reduced. Occurs.

  In addition, when the sending timing of either one of the front and rear sorting transmission chains 137, 137 is deviated, a difference in the conveying speed between the front and rear of the sorting and conveying conveyor 87 gradually starts to occur. The front and rear sorting transmission chains 137, 137 are connected by a plurality of transport bars 144, and the front and rear sorting drive sprockets 134, 134 are mounted on a single sorting and transporting drive shaft 134a. If there is a speed difference between the conveyance speeds of the above, the conveyance bars 144 and the sorting and conveyance drive shaft 134a are loaded.

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

  The sorting and conveying sprockets 134, 134 before and after being provided on the sorting and conveying drive shaft 134a are provided with members such as shear pins that preferentially break under load and prevent damage to other members. Since it is necessary to replace at least the shear pin, the carrot harvesting work is interrupted during the parts replacement, resulting in a significant decrease in work efficiency.

  In order to prevent this problem, front and rear guard covers 148, 148 are provided on the front and rear of the front and rear first transfer frames 77, 77 and on the upper surface of the recovery belt 133 of the recovery conveyor 160, and the front one is directed toward the rear side of the machine body. It is installed in a rearward-down inclining posture and the rear one is installed in a front-downward-inclining posture toward the front of the machine. One end of each of the front and rear guard covers 148, 148 faces above the transport start end of the recovery conveyor 160, and the other end faces above the transport start end of the selection transport conveyor 87.

  More specifically, it extends to the other side of the machine than the front and rear sorting drive sprockets 134, 134, which constitute the sorting / transporting conveyor 87, and the transport end portion of the collecting conveyor 160 and the residual leaf processing of the residual leaf processing conveyor 76. The earth and sand discharged from the roller 75 are guided by the front and rear guard covers 148, 148 to positions on the left and right sides of the machine with respect to the sorting drive sprockets 134, 134 and dropped below the sorting and conveying conveyor 87. It prevents the sand and sand from being caught between the sorting transmission chains 137.

  With the above configuration, the selection transmission chain 137 is lifted from the selection drive sprocket 134, and the so-called coma shift, which causes a shift in the sending timing of the selection transmission chain 137, is prevented from occurring, and a speed difference occurs between the front and rear positions of the selection transfer conveyor 87. As a result, it is possible to prevent the conveying bars 144 and the sorting and conveying drive shaft 134a from being distorted and the sorting and conveying conveyor 87 from being stopped.

  As a result, the ginseng harvesting work is not interrupted, the work efficiency is improved, and the ginseng can be harvested at a proper harvest time, so that the ginseng commercial value is improved. Further, it is not necessary to replace the parts, and the labor of the operator is reduced.

  Further, since the front and rear guard covers 148, 148 are inclined toward the center portion in the front-rear direction of the collection conveyor 160 and the sorting / conveying conveyor 87, the earth and sand on the guard covers 148, 148 are collected and conveyed by the collecting conveyor 160. Since it moves to the center part of the conveyor 87 in the front-rear direction, the earth and sand moving from the transfer end part of the recovery conveyor 160 to the transfer start end of the selection transfer conveyor 87 is prevented from approaching the front and rear selection drive sprockets 134, 134. Sediment is prevented from being caught between the sorting drive sprocket 134 and the sorting transmission chain 137.

  In addition to this, since the earth and sand moving from the residual leaf processing conveyor 76 to the sorting and conveying conveyor 87 also moves to the central portion in the front-rear direction of the sorting and conveying conveyor 87, the falling earth and sand is sorted by the sorting drive sprocket 134 and the sorting transmission chain 137. It is prevented from being caught between and.

  The front and rear guard covers 148, 148 can be mounted by inserting resin rivets into the front and rear first transport frames 77, 77, and when the guard covers 148 need to be replaced due to wear or the like. Since the guard cover 148 can be easily removed by pulling it up, the work of exchanging the guard cover 148 can be easily performed, and the work efficiency is improved.

  Further, if the rear end portions of the front and rear guard covers 148, 148, that is, the portions facing the conveyance start end portion of the sorting and conveying conveyor 87 are made to be more flexible than other portions by making cuts or the like, the front and rear guard covers 148 are formed. Since it is possible to prevent the 148, 148 from becoming a resistance when they come into contact with the transport bars 144, ... And the receiving bars 145, it is possible to prevent an excessive load from being applied to the sorting and transporting conveyor 87 and to prevent the durability from being lowered.

  The front and rear widths of the front and rear guard covers 148, 148 can prevent the sediment from falling on the front and rear sorting drive sprockets 134, 134 and the front and rear sorting transmission chains 137, 137, and further, the front and rear center of the recovery conveyor 160 and the sorting and conveying conveyor 87. It is about 60 to 90 mm in order to easily guide the earth and sand toward the section. The guard cover 148 on the front side of the fuselage is less likely to have dirt and sand entering than the guard cover 148 on the rear side, so the length of the above example is not necessary, but if the front and rear sides have the same length, common parts can be used. The cost can be reduced.

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

  As shown in FIGS. 2 and 7 to 11, the rotary shaft 93 is penetrated in the machine front-rear direction on the lower side (the other left and right side portions) of the second transfer frames 78, 78 in the front and rear of the sorting transfer conveyor 87 in the transfer direction. The frictional resistance members 94, 94 are provided on the front and rear ends of the rotary shaft 93 and outside the second transfer frames 78, 78, respectively.

  As the friction resistors 94, 94, any member having a strong friction resistance such as a disc spring, a spring washer, a rubber ring, etc. may be used.

  In addition, the base sides of the front and rear hanger arms 95, 95 are provided on the front and rear ends of the rotary shaft 93 outside the friction resistors 94, 94 in the front-rear direction, and the second transfer frames 78, 78 and the hanger arms 95, 95 are provided. The hanger arms 95, 95 are configured to be movable upward or downward only when a moving force higher than the resistance force is applied upward or downward by the frictional resistance of the frictional resistors 94, 94 sandwiched between the hanger arms 95 and 95.

  As shown in FIGS. 7, 9 and 10, the hanger arms 95, 95 have bent portions 95a, 95a formed at the substantially central portion in the left-right direction, and extend from the bent portions 95a, 95a to the outer end of the body. If the hanger arms 95, 95 are turned downward when the sorting / conveying conveyor 87 is lifted, the shape facing upward, that is, the shape bent in an inverted "H" shape when viewed from the front or the rear is provided. , The front and rear second transfer frames 78, 78 and the hanger arms 95, 95 are prevented from forming a gap, and even if the auxiliary worker extends his / her arm toward the transfer end of the sorting / transfer conveyor 87, the second transfer is performed. The arm is not caught 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 conveyance end side of the second transport frames 78, 78, the hanger frames 95, 95 are below the second transport frames 78, 78 regardless of the inclination angle of the hanger frames 95, 95. Since it is located at, the work space for selection of the auxiliary worker is widened, so that the selection accuracy is improved and the work efficiency is improved.

  Then, a hanger frame 96 protruding in the front-rear direction from the machine front-rear end of the sorting / conveying conveyor 87 is attached to the end of the hanger arms 95, 95 in the front-rear direction, and the carrots are attached to the front-rear end of the hanger frame 96. A pair of front and rear suspension hangers 98, 98 for suspending and supporting an accommodation bag (flexible container bag) 97 for accommodating 4) by hanging the front, rear, left, and right at four points are attached so as to be rotatable in the left-right direction.

  Further, the inverted U-shaped (∩-shaped) outer hanging bodies 99a and 99a facing upward are welded to the outer ends of the hanging hangers 98 and 98, respectively, and the inner ends of the body are downward facing U-shaped. The hanging hooks 99f, 99f, 99f, 99f for welding the inner hanging bodies 99b, 99b of the mold and for hanging the accommodating bag 97 on the outer hanging bodies 99a, 99a and the inner hanging bodies 99b, 99b can be moved vertically. 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 (∩ type), and the inner ends of the body are folded. May be bent in 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 have four corners of the accommodating bag 97 at the front and rear outer hanging bodies 99a, 99a and the front and rear so that the upper opening of the accommodating bag 97 to be suspended becomes a substantially square shape in a plan view. It is hung by the inner hanging bodies 99b and 99b.

  As shown in FIG. 10, the hanging hangers 98, 98 are removed from the hanger frame 96, and the outer hanging bodies 99a, 99a are hooked on the front and rear ends of the hanger frame 96 to remove the inner hanging bodies 99b, 99b. When the sorting conveyor 87 is rotated upward by being hooked on the support protrusion 119 provided on the outer side of the body of the recovery stand 118, which will be described later, the recovery stand 118 is pulled up by the hanging hangers 98, 98 to automatically accommodate the housing posture, that is, Since the posture can be made substantially orthogonal to the machine body frame 1, it is not necessary to manually lift the recovery table 118, and the labor of the worker is reduced.

  Further, when the sorting / transporting conveyor 87 is rotated to the upper limit to be in the stored state, the hanging hangers 98, 98 are in an orthogonal posture with respect to the machine body frame 1, so that there is no member 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 an extra storage space.

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

  Then, the lower limit regulation for receiving the front and rear hanger arms 95, 95 on the front and rear outside of the conveyance end portions of the second conveyance frames 78, 78 and on the outer side of the machine with respect to the mounting position of the rotation shaft 93 to regulate downward rotation. Attach the protrusions 100, 100. Further, an upper limit regulation that receives the hanger arm 95 on the front side of the machine body and regulates the upward rotation at a position outside the second transport frame 78 on the front side of the machine body and above the lower limit regulation protrusion 100 on the front side of the machine body and closer to the rotation shaft 93. Attach the protrusion 101.

  Further, a hole (not shown) having female threads is formed on the rear side or front and rear sides of the rotating shaft 93, and an adjusting knob 102 having a male screw (not shown) screwed into the hole is formed. The friction resistance is changed by inserting and rotating the adjusting knob 102 to change the front-rear distance between the hanger arms 95, 95 and the second selection frames 78, 78 sandwiching the friction resistance bodies 94, 94. It is configured to

  If the adjusting knob 102 is provided at the rear end of the body of the rotating shaft 93, it can be easily operated by an auxiliary worker who is on the auxiliary work seat 91. If the adjusting knob 102 is provided at the front end of the body of the rotating shaft 93, the operator can get on the control seat 11. It becomes easier for the worker to operate, and the frictional resistance force of the frictional resistance bodies 94, 94 can be easily adjusted.

  Further, a slide shaft 103 slidable in the front-rear direction is provided below the second transfer frame 78 on the rear side of the machine body and on the transfer end side of the selection transfer conveyor 87 with respect to the rotating shaft 93. A spring 104 that applies a biasing force to the front side of the machine is attached. An auxiliary hook 105 is provided at the front end of the spring 104 to prevent the looseness by suspending the front and rear intermediate portions inside the fuselage bag 97 that enter the lower part of the sorting and conveying conveyor 87, and the rear side of the slide shaft 103. An operator attaches a slide knob 106 that slides the slide shaft 103 back and forth at the end portion and outside the second frame 78.

  Then, the slide knob 106 is provided with a hook lever 106a that makes it easy for an operator to manually operate the slide knob 106, and the hook lever 106a is provided at the base of the hook lever 106a toward the sorting and conveying conveyor 87 side, that is, the inside of the machine body. Attach a torque spring 106b that urges.

  Since the hook lever 106a is brought into contact with the inside of the body of the accommodation bag 97 during the harvesting operation to bias the inside of the body of the accommodation bag 97, it is possible to prevent the occurrence of slack inside the accommodation bag 97. Thus, it is possible to prevent carrots from entering the slack to waste the storage amount, and it becomes unnecessary to frequently exchange the storage bag 97, and the work efficiency is improved. Further, by mounting a tube made of a soft material such as rubber on the surface of the hook lever 106a, it is possible to prevent the carrot housed in the housing bag 97 from coming into contact with the hook lever 106a and being damaged. improves.

  In addition to this, since the visor plate 126 rotates together with the hanger frame 96 and is always in a substantially horizontal posture with the hanging hangers 98, 98, even if the sorting / conveying conveyor 87 is moved up and down, direct sunlight stays inside the accommodation bag 97. It is hard to enter, the deterioration of carrots can be prevented, the commercial value can be improved, and the visor plate 126 can be prevented from hindering the movement of the hanging hangers 98, 98.

  Furthermore, since the hook lever 106a is pressed against the bottom of the sorting / conveying conveyor 87 by the force of the torque spring 106b when not in operation (stored), the hook lever 106a is prevented from protruding outside the machine body. The hook lever 106a is prevented from being damaged by contact during storage, and an extra storage space is not taken.

  When the slide shaft 103 is not operated, if the slide shaft 103 is provided from the rear end of the body of the sorting and conveying conveyor 87 to the same as the front-rear intermediate portion or slightly to the front side of the body, the position of the auxiliary hook 105 can be easily aligned. Further, the slide shaft 103 may be provided from the front side to the rear side of the machine body, and in this case, an operator who rides on the control seat 11 can operate the slide shaft 103.

  Then, as shown in FIG. 11, a sling band hook 107 for hooking a sling band 97i on the inside of the body of the accommodation bag 97 below the sorting / transporting conveyor 87 and on the transport direction upper side of the sorting / transporting conveyor 87 than the rotating shaft 93. And a suspension band pin 108 for hooking a suspension band 97o on the outside of the machine body is arranged on the upper part of the hanger frame 96 so as to face the upper side of the machine body.

  The suspension bands 97i and 97o on the outside of the machine body are members for hanging the storage bag 97 that stores carrots on a forklift or a hoist and suspending them.

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

  At the start of the carrot harvesting operation, the sorting / transporting conveyor 87 is lowered to the lowest position in order to minimize the fall distance of the ginseng from the transporting end portion of the sorting / transporting 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 and the inner hanging bodies 99b, 99b of the front and rear hanging hangers 98, 98, respectively. The opening has a substantially rectangular 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 restricting protrusion 101, and the front and rear suspension hangers 98, 98 are tilted upward from the inner end of the body toward the outer end thereof. To do. Since the hanging hangers 98, 98 are inclined upward toward the outer side of the machine body, the suspended storage bag 97 is also inclined upward from the inner side end of the machine body toward the outer side end of the machine body. It becomes a posture.

  At this time, in the suspended storage bag 97, the inside of the machine body from which the carrot is discharged from the transfer end side of the sorting / conveying conveyor 87 is slackened, so that the vertical length is shortened, and the outside of the machine body is hardly slackened, and thus the upper and lower sides. The length becomes longer. The accommodating bag 97 is made of a flexible material such as cloth or synthetic fiber.

  Further, the outside end of the body of the discharge shooter 89 is inserted into the inside end of the accommodation bag 97, and the inside end of the accommodation bag 97 is inserted below the conveyance end side of the sorting and conveying conveyor 87 to form the accommodation bag 97. The auxiliary hook 105 is hooked in a hanging hole (not shown) formed in the substantially central portion in the front-rear direction. Further, the hanging band 97i on the inside of the body of the accommodation 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 posture set by the operator due to the frictional resistance force of the frictional resistance bodies 94, 94. However, if the hanger arms 95, 95 start to rotate downward if left unattended, the adjustment knob 102 is rotated. Thus, the frictional resistance force of the frictional resistance bodies 94, 94 arranged between the second transfer 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 contact pressure of the friction resistors 94, 94 increase and the friction resistance becomes stronger, and the hanger arms 95, 95 are prevented from moving freely. It should be noted that when rotating in the loosening direction, the contact area and the contact pressure of the friction resistors 94, 94 decrease, and the friction resistance becomes weak.

  When the harvesting work progresses and the amount of ginseng stored in the storage bag 97 exceeds a certain amount, an auxiliary worker steps on the extension side of the elevating operation pedal 92, extends the elevating cylinder 88, and extends the elevating cylinder 88. Raise the transfer end side.

  While the sorting / conveying conveyor 87 is moving upward, the force that the hanger arms 95, 95 try to lower exceeds the friction resistance of the friction resistors 96, 96, so that the hanger arms 95, 95 descend. The lowering of the hanger arms 95, 95 occurs only while the sorting / conveying conveyor 87 is being raised to secure a storage space for carrots in the storage bag 97.

  As the hanger arms 95, 95 rotate downward, the hanging hangers 98, 98 rotate about the hanger frame 96 as a fulcrum, the outside of the hanging hanger 98.98 rotates downward, and the inside of the fuselage moves inside. Rotate upwards. The outside of the housing of the accommodation bag 97 is located at the upper side at the stage of installation, so that the position thereof hardly changes, but the inside of the housing is pulled up by the movement of the hanging hangers 98, 98. As a result, the slack that has occurred inside the storage bag 97 inside the machine body is eliminated according to the amount of rise.

  Note that there is almost no change in the drop between the transport end of the sorting / transporting conveyor 87 and the storage bag 97 due to this operation, and the end of the discharge shooter 89 hangs inside the storage bag 97, so that the storage bag is accommodated. It does not protrude from 97.

  When the harvesting work progresses and the carrots stored in the storage bag 97 exceed a certain amount, the transport end of the sorting / transporting conveyor 87 is raised, the hanger arms 95, 95 are rotated downward, and the storage bag 97 is received. The inside of the machine is pulled up to secure an accommodation space for the carrot in the accommodation bag 97, and the mountain of the carrot that is biased toward the inside of the machine is destroyed.

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

  However, when it is troublesome to replace the storage bag 97, such as when all the carrots in the field can be harvested within a few meters, the lid portion that closes the upper opening of the storage bag 97 is hung to suspend the hanger 98, 98. Hooking on the outer hanging bodies 99a, 99a and increasing the vertical height from the outside of the body of the accommodating bag 97 to the vicinity of the central part in the left-right direction, a carrot of several meters (a few kg) can be accommodated. The labor of exchanging the bag 97 can be saved and the work efficiency can be improved.

  Even in this state, there is almost no change in the drop between the transport end of the sorting / transporting conveyor 87 and the storage bag 97.

  Then, when the accommodation bag 97 is fully filled, the machine body, the pulling and conveying device 24, the sorting conveyer 87 and the like are stopped, the accommodating bag 97 is removed from the hanging hooks 99f, 99f, 99f, 99f, and the hook lever 106a is removed. The auxiliary hook 105 is removed from the accommodating bag 97 by operating it and pulling it rearward of the machine body via the slide knob 106. When the auxiliary hook 105 is released from the hook lever 106a by the urging force of the spring 104, the auxiliary hook 105 automatically returns to the sorting / conveying conveyor 87 and to the approximate center portion of the accommodation bag 97 in the front-rear direction when mounted.

  Further, by operating the operation handle 116 and lowering the mounting table 112 forward or backward, the storage bag 97 in which carrots are stored slides down the mounting table 112 by its own weight, so the storage bag 97 is lowered to the front side of the machine body. 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 moved forward, so that the storage bag 97 accommodating about 200 kg of ginseng is unloaded from the storage section G and installed in the field.

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

  With the above configuration and operation, since the slack hardly occurs on the outside of the body of the accommodation bag 97 from the start of the work to the replacement, it is prevented that carrots enter the slack and reduce the accommodation amount of the accommodation bag 97. The frequency of replacement of the bag 97 is reduced, the work efficiency is replaced, and the labor of the worker is reduced.

  In the conventional method of attaching the storage bag, slack occurs on both sides inside and outside the body, so carrots enter this slack, and even if the storage bag is lifted, the slack cannot be removed, the amount of storage at one time is reduced, and the storage bag is replaced. The frequency was increasing.

  Also, it was possible to eliminate the slack that occurred in the storage bag by moving the sorting and conveying conveyor up and down to secure a storage space, but each time the slack was removed, the worker had to operate the sorting and conveying conveyor, It was reducing the efficiency. Particularly, in the case of an assistant worker who performs sorting, the sorting accuracy during the operation was lowered.

  Since the drop between the transport end of the sorting / transporting conveyor 87 and the one side of the storage bag 97 on the left and right sides of the machine body is always substantially constant, it is possible to prevent the ginseng from being damaged by the impact of the fall, and the product value of the ginseng is improved. To do.

  Further, normally, the rotation of the hanger arms 95, 95 is restricted by the friction resistors 96, 96, and the hanger arms 95, 95 are rotated downward only while the sorting / conveying conveyor 87 is being raised. When the sorting / conveying conveyor 87 is operated in accordance with the change in the amount of ginseng stored in the storage bag 97, the insides of the hanging hangers 98, 98 can be moved upward, so that the storage amount of the storage bag 97 is automatically adjusted. Since the slack inside the body of the accommodation bag 97 is automatically eliminated, it is not necessary to move the sorting / conveying conveyor 87 up and down to remove the slack, and the working efficiency is remarkably improved.

  Further, by providing the upper limit regulating projection 101 that determines the limit of the upward tilted posture of the hanger arms 95, 95 on the second transport frame 78 on the front side of the machine body, the operator can easily understand the position where the hanger arms 98, 98 are set. The positions of the hanger arms 95, 95 can be determined so that the storage bag 97 is full.

  In addition, since the upper limit regulation protrusion 101 is provided only on the second transport frame 78 on the front side of the machine body, the upper limit regulation protrusion 101 is within the work range of the assistant worker who sorts the carrots being transported by the sorting transport conveyor 87. Since it does not exist, it is prevented that the auxiliary worker collides with or gets caught in clothes when operating, 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 body, but the position where the lower limit regulating members 100, 100 are provided is located at the inside end of the machine body of the hanging hangers 98, 98, and the normal sorting operation is completed. Since it is a region in which there is no interference with the operation of the auxiliary worker, there is no problem.

  In addition, in order to prevent the worker from forgetting to bring the hanger arms 95, 95 into contact with the upper-stage regulation protrusion 101, a caution note may be written on the second transport frame 78 on the rear side to prevent forgetting the setting.

  Then, the outer hangers 99a, 99a are provided upward at the machine outer ends of the hanging hangers 98, 98, and the inner hangers 99b, 99b are provided at the machine inner ends, so that the suspension inside the machine is suspended. Since the lowering hooks 99f, 99f are located below the hanging hooks 99f, 99f on the outside of the machine, when the accommodation bag 97 is installed, the difference in vertical height between the outside and the inside of the accommodation bag 97 becomes large. It is more difficult for carrots to spill from the outside of the housing bag 97.

  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 rod can be formed of a single rod, so that the cost can be reduced.

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

  Further, by hooking the auxiliary hook 105 into the hole in the substantially central portion of the accommodation bag 97 in the front-rear direction, it is possible to reduce the slack that occurs in the approximately central portion of the accommodation bag 97 in the longitudinal direction of the accommodation bag. It is difficult to get into the slack and secure enough storage space.

  When the slide knob 106 is pulled rearward of the machine body, the slide shaft 103 slides rearward of the machine body and the auxiliary hook 105 comes off the accommodation bag 97. Therefore, the accommodation bag 97 filled with carrots and the transportation of the sorting conveyor 87 Since it is possible to remove the auxiliary hook 105 without having to put a hand into a narrow space formed between the end portion and the lower side, the work efficiency is improved and the labor of the worker is reduced.

  Further, when the hanger arms 95, 95 are brought into contact with the upper limit restricting protrusion 101 and the sorting / conveying conveyor 87 is rotated to the uppermost position, the hanging hangers 98, 98 are rotated and the outer ends of the hanging hangers 98, 98 on the body side. Since the portion is located inside the end portion of the machine body frame 1, the hanging hangers 98, 98 protruding from the machine body frame 1 do not hit the wall or the like, and damage to the machine body is prevented.

Further, since the end portion of the discharge shooter 89 hangs down inside the storage bag 97, there is no space between the discharge shooter 89 and the storage bag 97 in which carrots can fall, so that the discharge conveyor 87 discharges the carrot. The ginseng can be prevented from falling and the product value of the ginseng is improved.
If the width of the discharge shooter 89 in the machine front-rear direction is substantially the same as the width of the sorting and conveying conveyor 87 in the machine front-rear direction, the carrot fall prevention effect is further improved.

  Next, the configuration of the placement and discharge section H will be described.

  As shown in FIG. 2, FIG. 17, and FIG. 18, a loading / unloading frame 109 projecting to the outside of the machine is provided at the rear part on the left and right sides of the machine body frame 1 and is housed in the loading / unloading frame 109 so as to be vertically rotatable. A mounting table 110 is provided. The storage / placing table 110 rotates around a base on the front side of the machine body, and when rotated downward, it rotates until the rear side of the machine body comes into contact with a field scene, and when rotated upward, the storage / mounting table 110 and the machine body frame 1 are separated from each other. Line up in a substantially horizontal position.

  Then, a placement discharge actuator 111 for rotating the storage platform 110 is provided at an end of the placement discharge frame 109 on the inner side of the machine body, and an operation switch (not shown) of the placement discharge actuator 111 is provided. The operation switch is provided on one of or both of the operation panel 12, the second transport frame 78 on the side where the auxiliary work seat 91 is provided, or the inside end of the body of the placement and ejection frame 109.

  The accommodation table 110 has a front wall portion 110a for receiving the accommodation bag 97 on the front side of the machine body and left and right side walls 110b, 110b on both left and right sides of the machine body, and a discharge space portion 110c for ejecting the accommodation bag 97 on the rear side of the machine body. ..
