When 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, the tension plate 52L or the tension plate when the large diameter foliage passes between the left and right of the alignment devices 54L and 54R. Since the alignment chain 48 and the alignment guide body 52 move to the side without the 52R, even if the diameter of the carrot foliage is large, it can be prevented from being bitten by the alignment devices 54L and 54R, and the aircraft is stopped. It is not necessary to remove the bitten foliage and 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 urging springs 50 and 50, the alignment chains 48 and 48 will be in an appropriate position when the large-diameter foliage passes and a load is applied. Can be bent and retracted, and can be prevented from being bitten by 54L and 54R, and it is not necessary to stop the body and remove the bitten foliage, thereby improving work efficiency.

  Then, elongated holes are 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 surfaces of the alignment guide bodies 52, 52 are formed in the elongated holes. The left and right scrapers 55 and 55 for removing pieces and mud of the foliage adhering to the head are attached along the locus of the alignment guide bodies 52 and 52 at the time of position adjustment.

In addition, the scrapers 55 and 55 are arranged in a rearward downward inclined posture, so that it becomes easy to drop the cut ends of the foliage and mud downward.
Then, left and right cutting blade rotation shafts 56 and 56 are attached to the rear positions of the alignment devices 54L and 54R of the left and right first gear units 38 and 38, and left and right bearings 57 and 56 are mounted on the cutting blade rotation shafts 56 and 56, respectively. 57 is attached rotatably. 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 60, 60 are attached to the support plates 59, 59 to constitute a foliage cutting device 61.

  Further, left and right foliage conveyance drive pulleys 62 and 62 are attached to the left and right first output shafts 40 and 40, and the left and right foliage conveyance drive pulleys 62 and 62 are attached to the front side of the machine body above the left and right first gear units 38 and 38 and above the alignment devices 54L and 54R. The foliage driven pulleys 63 and 63 are rotatably attached. Then, the left and right foliage conveying belts 64, 64 are wound around the left and right foliage conveying drive pulleys 62, 62 and the left and right foliage conveying driven pulleys 63, 63 to endlessly form the carrot foliage from the pulling and conveying device 24. Is disposed below the left and right transmission cases 37 and 37 and below the end of conveyance of the pulling and conveying device 24.

  Further, left and right remaining leaf conveyance drive pulleys 66 and 66 are pivotally attached to the upper ends of the left and right first output shafts 40 and 40, and the left and right remaining leaf conveyance driven pulleys 67 and 67 are rotatable above the transmission cases 37 and 37. A plurality of left and right remaining leaf conveyance tension pulleys 68, 68 are attached between the left and right remaining leaf conveyance driving pulleys 66, 66 and the left and right remaining leaf conveyance driven pulleys 67, 67. Then, left and right residual leaf conveyance belts 69, 69 are wound endlessly around the left and right residual leaf conveyance driving pulleys 66, 66, left and right residual leaf conveyance driven pulleys 67, 67, and left and right residual leaf conveyance tension pulleys 68, 68. Thus, the remaining leaf conveyance device 70 that sandwiches the upper part of the foliage and conveys it to the rear of the machine body is configured above the defoliation conveyance device 65.

A foliage shooter 71 for discharging the foliage cut by the foliage cutting device 61 from the end portions of the above-mentioned foliage conveyance device 65 and the remaining leaf conveyance device 70 to the field is provided to constitute the foliage cutting portion D.
With the above configuration, the left and right alignment drive sprockets 42 and 42 are arranged at positions separated from the left and right spacing portions of the alignment devices 54L and 54R through which the foliage passes, so that the alignment drive sprockets 42 and 42 Since it is possible to prevent the stems and leaves from being entangled with the two output shafts 41 and 41 to stop the alignment devices 54L and 54R, the harvesting operation is not interrupted and the work efficiency is improved.

  In addition, since the alignment drive sprockets 42, 42 have a smaller diameter than the alignment driven sprockets 45, 45 and the alignment tension sprockets 47, 47, the alignment drive sprockets 42, 42 are further left and right of the alignment devices 54L, 54R. Since it leaves | separates from a space | interval part, it can further prevent that a foliage part gets entangled with the alignment drive sprockets 42 and 42 and the 2nd output shafts 41 and 41, and working efficiency further improves.

  And 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 are brought into contact with the alignment devices 54L, 54R. The resulting slack can be absorbed, and the alignment chains 48 and 48 immediately return to the tensioned state, so that the alignment devices 54L and 54R reliably ensure that the alignment devices 54L and 54R have ginseng foliage even when the foliage portions having different diameters pass continuously. The cutting position of the carrot foliage is properly aligned and the foliage is cut appropriately, and there is no need to remove the foliage in a later process, improving the work efficiency.

  Further, 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 carrots, the difference in the diameter of the foliage depending on the variety, or the weather and soil quality The tension can be changed appropriately according to the working conditions at the work place, etc., so that the stems and leaves remaining in the carrots are removed in the subsequent process by properly aligning the carrot foliage cutting position and cutting the foliage parts reliably. This eliminates the need for 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 having the alignment driven sprockets 45, 45 attached to the holes 44, 44 are movable. In the state where no load is applied, the alignment driven sprockets 45, 45 urged by the urging springs 50, 50 move toward the conveyance path of the foliage, so that the small foliage passes through. Thus, the alignment devices 54L and 54R can receive the foliage portion to properly align the cutting position of the ginseng foliage portion, eliminating the need to remove the foliage portion remaining in the ginseng in a later process, and improving the work efficiency.

  Further, when a large load is applied to the left and right alignment devices 54L and 54R when the large diameter foliage part passes, the alignment driven sprockets 45 and 45 are separated from the movement path of the foliage part along the holes 44 and 44. Since the left and right intervals on the front side of the alignment devices 54L and 54R are widened, the foliage can be prevented from being caught in the interval portions of the alignment devices 54L and 54R, and the aircraft is stopped and bitten. There is no need to remove the foliage and the work efficiency is improved.

  If it is known before harvesting that the carrot foliage has a large diameter, move the alignment driven sprockets 45, 45 away from the left and right of the left and right alignment devices 54L, 54R. If the left and right distances on the upper side in the conveying direction of the alignment devices 54L and 54R are widened, the alignment devices 54L and 54R can be prevented from biting the foliage, and it is necessary to remove the bitten foliage. No work efficiency is improved.

  And, by attaching the guide cover 51 to each of the plurality of links 48a constituting the alignment chains 48, 48 and configuring the alignment guide body 52, the guide cover 51 at an arbitrary location can be freely attached and detached. Even if some of the guide covers 51 are damaged, the proper alignment performance is maintained by simply replacing the guide covers 51 with new ones, and the foliage is appropriately cut, so that the work efficiency is improved.

Moreover, since it is not necessary to replace the entire alignment guide body 52, the cost can be reduced.
Furthermore, since the guide cover 51 can be attached and detached manually without the need for a tool, the replacement work can be easily performed.

  Since the guide cover 51 has a U-shape in front view covering the contact surfaces of the upper and lower surfaces of the alignment chain 48 and the foliage, a space portion is generated between the guide cover 51 and the alignment chain 48. As a result, the foliage is sandwiched between the guide cover 51 and the alignment chain 48, so that ginseng is not aligned at the proper cutting position and the foliage is left uncut, and the foliage is removed in a later process. The work efficiency is improved, the carrot root is prevented from being cut, and the product value of the carrot is improved.

  Further, a convex R portion 51 a and a concave R portion 51 b are formed on the guide cover 51, and the convex R portion 51 a of the subsequent guide cover 51 is brought close to the concave R portion 51 b of the front guide cover 51. By attaching to the alignment chain 48, when the alignment chain 48 moves around the alignment driven sprocket 45 or the like in an arc orbit, the guide cover 51 can move following, so that the alignment devices 54L and 54R Since it operates at a constant peripheral speed, it is possible to properly align the cutting positions of the carrot foliage by receiving the foliage, eliminating the need for removing the foliage remaining in the carrot in a later step, and improving the work efficiency.

  Furthermore, by providing a protruding portion 51c that protrudes toward the convex R portion 51a, when the alignment chain 48 moves around the alignment driven sprocket 45 or the like in an arc orbit, the guide covers 51 ... Since this protrusion 51c covers the space formed between the front and rear, the foliage is sandwiched between the space between the front and back of the guide covers 51, so that the ginseng is not aligned at an appropriate cutting position and the foliage is left uncut. This eliminates the need to remove the foliage in the subsequent process, improves the work efficiency, prevents the carrot root from being cut, and improves the product value of the carrot.

  When the right and left tension plates 53L and 53R are provided in the winding region of the alignment chains 48 and 48, the alignment chains 48 and 48 are pressed from within the winding region. Since the alignment chains 48 and 48 of the portion where the tension plate 53L or the tension plate 53R is not pressed can be retracted in the direction of the alignment drive sprockets 42 and 42, the foliage is bitten between the right and left of the alignment devices 54L and 54R. There is no need to remove the foliage that has been bitten by stopping the airframe, and the work efficiency is improved.

  Further, by providing left and right scrapers 55 and 55 for scrubbing debris and dirt such as mud adhering to the alignment guide bodies 52 and 52 moving on the outer periphery of the alignment drive sprockets 42 and 42, Since it is possible to remove the foreign matter adhering to the alignment guide bodies 52 and 52 at a position away from the moving path of the parts, the foliage fragments are prevented from getting entangled with each part of the alignment devices 54L and 54R. It is not necessary to remove the entangled stem and leaf fragments, and the work efficiency is improved, and the mud mass is prevented from damaging the root of the carrot, thereby improving the product value of the carrot.

  Furthermore, since the attachment positions of the scrapers 55 and 55 can be changed along the elongated holes, the scrapers 55 and 55 are set at optimum positions in accordance with the average diameter of the ginseng stalks and leaves of the field where the harvesting operation is performed. The above effect is further improved by reliably removing the debris of the foliage and dirt such as mud from the alignment guide body 52 and the office work 52.

  And the leaf shooter 71 which discharges the leaf leaves cut from the carrot by the stem-and-leaf cutting device 61 (the cut stem and leaf portion) to the field seems to discharge the leaves and leaves to the already dug side (the side where the carrot has been harvested). Is provided in a downwardly inclined position, the discharged stems and leaves fall on the carrots on the undigged side (the side where the carrots are not harvested), and the drainage leaves the left and right nipping and conveying belts 19 and 19 and the left and right driven Since it is possible to prevent the harvesting section C from being stopped by being entangled with the pulleys 17, 17, etc., it is possible to prevent the harvesting operation from being disturbed. Can be prevented.

Next, the remaining leaf processing unit E will be described.
As shown in FIGS. 1 to 8, front and rear residual leaf processing frames 72 and 72 are provided below the foliage cutting device 61, and the first residual leaf processing is performed between the left and right sides of the left and right sides of the body of the residual leaf processing frames 72 and 72. A drive roller 73a is rotatably attached. A second remaining leaf processing drive roller 73b is rotatably mounted between the left and right sides of the left and right sides of the left and right sides of the remaining leaf processing frames 72 and 72 and below the first remaining leaf processing roller 73a. Then, a remaining leaf processing belt 74 made of an elastic material such as rubber or urethane is wound around the first remaining leaf processing driving roller 73a and the second remaining leaf processing driving roller 73b in an endless manner. Further, a remaining leaf processing roller 75 is attached to the upper portion of the remaining leaf processing belt 74 so that the remaining leaves remaining at the root of the carrot are sandwiched together with the remaining leaf processing belt 74 and rotated to be excised. The remaining leaf processing section E is configured by configuring the remaining leaf processing conveyor 76 that transports the remaining leaves from the outside of the machine body to the left and right inside directions while processing the remaining leaves.

The remaining leaf processing conveyor 76 is inclined about 2 to 5 degrees from the left and right sides of the machine body to the other side.
Thereby, since the carrot which fell is moved by the drive and inclination movement of the remaining leaf processing belt 74, the movement of the carrot does not stop on the remaining leaf processing conveyor 76, and it is necessary to move the carrot stopped manually. No work efficiency is improved. Further, 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 inclined to the left and right sides depending on the state of the field. Since the carrot remains in a substantially horizontal state, the carrot does not stagnate on the remaining leaf processing conveyor 76 and does not move in the direction opposite to the conveying direction of the remaining leaf processing conveyor 76. There is no need to return it and work efficiency is improved.

  With the above configuration, since the remaining leaf processing roller 75 constituting the remaining leaf processing conveyor 76 cuts off the remaining leaves of carrots cut by the stem and leaf cutting device 61, the operation of manually cutting the remaining leaves after the harvesting operation is omitted. Work efficiency can be improved.

  In addition, the remaining leaf processing belt 74 constituting the remaining leaf processing conveyor 76 is made of an elastic body such as rubber or urethane, so that the remaining leaf processing belt is removed even if carrots fall after the leaves are cut off by the foliage cutting device 61. Since 74 reduces the impact of the drop, the carrot is prevented from being damaged by the impact of the drop, and the quality of the carrot is improved.

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

For this reason, the recovery driving roller 132a may be disposed below the recovery driven roller 132b, and the recovery conveyor 160 may be configured to be inclined downward from the left and right sides of the machine body to the left and right sides.

  With the above configuration, even if carrots may fall in the middle of transportation due to the foliage being cut, the carrots can move to the sorting transport conveyor 87 via the recovery conveyor 160 and return to the original movement path. There is no need to pick up the carrots that have fallen out of the transport path, and the labor of the operator is reduced.

  In addition, by arranging the collection driven roller 132 below the conveying surface of the remaining leaf processing conveyor 76, when a large amount of carrots are supplied all at once, the carrot is not in contact with the remaining leaf processing roller 75 but on the front side of the machine body. Even under the condition of being pushed out, the carrots that have been pushed out can move to the collection conveyor 160 without stagnation, so that the carrot harvesting work is prevented from stagnation, and the work efficiency is improved.

  Further, when the collection conveyor 160 is inclined downward from the left and right sides of the machine body to the left and right sides, the carrot received by the collection conveyor 160 can roll by its own weight and move toward the sorting and conveying conveyor 87. Since the carrots stay on the conveyor 160 and are prevented from coming into contact with the carrot falling from above while being transported to the sorting and conveying conveyor 87 side, the carrot is prevented from being damaged, and the product value of the carrot is improved.

Then, the rotation returns to normal rotation, so that the rotation cycle of the sorting and conveying conveyor 87 is prevented from being irregularly irregular, the amount of carrot conveyance is stabilized, and the sorting accuracy and work efficiency are improved.

  Furthermore, even if a load is applied to one sorting output sprocket 207, the other sorting output sprocket 207 is not loaded, so that the damaged portion is prevented from expanding, and the time and labor required for repair and parts used for repair Reduction.

  In addition, since one of the front and rear sorting drive sprockets 203 and 203 and the sorting input sprockets 204 and 204 has a larger diameter than the other, the mounting positions of the front and rear sorting drive sprockets 203 and 203 and the sorting input sprockets 204 and 204 Can be reversed, the conveying speed of the sorting conveyor 87 can be increased or decreased.

  When the amount of ginseng expected to be harvested is large and the sorting and conveying conveyor 87 can always carry a large amount of ginseng, the sorting driving sprockets 203 and 203 and the sorting input sprockets 204 and 204 become slower in the sorting and conveying conveyor 87. This makes it easier to find carrots that are not suitable for harvesting, thus improving the sorting accuracy.

  When the amount of ginseng expected to be harvested is small and the amount of ginseng transported by the sorting and conveying conveyor 87 can be reduced, the sorting drive sprockets 203 and 203 and the sorting input sprocket 204 and the like that the conveying speed of the sorting and conveying conveyor 87 is increased. With the arrangement of 204, the time until the carrot is stored in the storage container 97 is shortened, and the work efficiency is improved.

  Then, by covering the output shaft of the sorting drive rotating shaft 202 and the sorting drive motor 201 with the protective pipe 208, impurities such as soil and foliage adhere to the output shaft of the sorting drive rotating shaft 202 and the sorting drive motor 201. Therefore, the rotation of the sorting drive rotating shaft 202 and the output shaft of the sorting drive motor 201 is prevented from being hindered, the sorting accuracy and work efficiency are improved, and the durability due to wear is prevented from being lowered.

  Further, by connecting the front and rear second transport frames 78 and 78 with the protective pipe 208 and the rotating shaft 93, the strength member of the sorting and conveying conveyor 87 is obtained, so that the durability of the sorting and conveying device 87 is improved.

  Further, by forming the front inclined portion 200fd and the rear inclined portion 200r in the front and rear sorting transmission cases 200f and 200r, it is possible to drop the soil that has been peeled off from the carrots during the sorting operation and the foreign matter flying by the wind or the like. As a result, the sorting and conveying conveyor 87 is less likely to accumulate dirt and foreign matter, and the time and labor required for cleaning are reduced.

  Since the sorting drive motor 201 is arranged on the front side of the machine body of the sorting power transmission case 200f on the front side, the sorting drive motor 201 can be arranged between the sorting conveyance unit F and the control unit B. And other members are prevented from interfering with each other.

  Further, the front and rear tension rods 210, 210 are moved in the left-right direction so that the tension on the upper side in the conveying direction of the output shaft of the sorting drive rotating shaft 202 and the sorting drive motor 201 can be adjusted, so The slack of the chains 205 and 205 is prevented, the rotation cycle of the sorting and conveying conveyor 87 is prevented from being irregularly disturbed, the amount of carrot transported is stabilized, and the sorting accuracy and work efficiency are improved.

  Alternatively, it is possible to prevent the front and rear sorting transmission chains 205, 205 from being excessively stretched and breaking with a slight load, so that durability is improved and work is prevented from being interrupted.

  As described above, the sorting and conveying conveyor 87 is driven from the lower side in the conveying direction. Thus, a pair of front and rear sorting driven sprockets 213 and 213 are provided on the driven rotation side of the sorting and conveying conveyor 87, that is, on the upper side in the conveying direction, and the driven rotating shaft 214 in the front and rear direction is provided. A plurality of tension sprockets 215 and 215 are provided between the front and rear of the output sprockets 207 and 207 via tension rotating shafts 216... And the front and rear sorting transmission chains 217 and 217 are wound endlessly.

  Also, a plurality of transport bars 144... For placing and transporting carrots between the front and rear sorting transmission chains 217, 217 are provided at equal intervals in the left-right direction, that is, with a left-right distance L 1. Receiving bars 145... For preventing the carrots from rolling down at the upper inclined portion of the sorting and conveying conveyor 87 are arranged at predetermined intervals. Further, by providing the second transport frames 78 and 78 with chain covers 146 and 146 that cover the top of the sorting transmission chains 217 and 217, a sorting and transporting conveyor 87 is configured.

  As shown in FIG. 5, a left and right interval at which ginseng can fall is opened between the transport start end of the sorting transport conveyor 87 and the transport end of the recovery conveyor 160, and the transport start end of the sorting transport conveyor 87. Is located below the end of conveyance of the recovery conveyor 160, the carrots discharged from the end of conveyance of the recovery conveyor 160 are transferred to the front and rear remaining leaf processing frames 72 and 72 by the selection and conveyance conveyor 87. The takeover shooter 147 to be moved to the start end portion is arranged in a posture in which the takeover shooter 147 is inclined downward from the left and right sides of the body toward the other side in the rear view.

  The takeover shooter 147 prevents rubber from being damaged even if it comes into contact with carrots, and also prevents any resistance from coming into contact with the transport bars 144 of the sorting transport conveyor 87, such as rubber or synthetic resin. When composed of a soft member, the carrot is prevented from being damaged and the product value of the carrot is maintained, and the driving rotation of the sorting and conveying conveyor 87 is disturbed to prevent the carrot from being delayed, thereby improving work efficiency. .

  As described above, since the sorting and conveying conveyor 87 is positioned below the remaining leaf processing conveyor 76, the stagnation of the transfer of carrots from the remaining leaf processing conveyor 76 to the sorting and conveying conveyor 87 is also prevented, so that the work efficiency is further improved. As well as improving, the product value of carrots is prevented from decreasing.

  Further, by arranging the transport bars 144 in the left-right direction with a left-right interval L1, the earth and sand carried together with the carrots and the remaining leaves removed by the remaining leaf processing roller 75 are sorted and conveyed from the left-right interval L1. Since it can be dropped below 87, the earth and sand and the remaining leaves entering the storage container 97 are reduced, and the capacity of the storage container 97 can be accommodated with carrots. As a result, the frequency of replacing the storage container 97 is reduced, and the work efficiency is improved.

  Furthermore, since the receiving bars 145 are provided at a wider interval than the transport bar 144, even if the carrots roll on the sorting and conveying conveyor 87, the receiving bars 145 stop the movement of the carrots. Since it is prevented from returning to the conveyance start end portion, the work efficiency is improved and the carrot is prevented from coming into contact with and being damaged when it falls down, so that the commercial value of the carrot is maintained.

  The transport bar 144 is formed of a carrot from the recovery conveyor 160 and the remaining leaf processing conveyor 76 when a high-strength elastic body such as hard rubber or a soft elastic body such as soft rubber is wrapped around the outer periphery of a rod-shaped metal. Since the carrot can be prevented from being damaged by the impact of contact when taking over the carrot, the product value of the carrot is improved.

  Further, when the receiving bar 145 has a structure in which a rivet or a bolt (not shown) is mounted from the opposite side of the conveying surface, that is, from the lower side and attached to the sorting transmission chain 217, the rivet or bolt is installed in the winding area of the sorting transmission chain 217. Since the bolts do not protrude, interference with other members is prevented, so that the sorting and conveying conveyor 87 is prevented from being damaged, and the carrots being conveyed are prevented from coming into contact with the rivets and bolts and being damaged. The product value of will improve.

  Then, a support plate 86 is attached between the left and right of the second transport frames 78 and 78, and a lifting cylinder 88 that moves the transport terminal end side of the sorting transport conveyor 87 up and down between the support plate 86 and the machine frame 1 is expanded and contracted. A sorting and conveying conveyor 87 that freely attaches and conveys carrots from the left and right sides of the machine body to the left and right sides is configured. Further, a discharge shooter 89 made of a soft member such as a rubber plate or a vinyl chloride plate that slides and moves the carrot discharged from the transfer terminal portion of the sorting and conveying conveyor 87 to the lower portion of the transfer terminal portion of the sorting and conveying conveyor 87. Attach so that the end hangs downward.

The lifting cylinder 88 may be electric, hydraulic or pneumatic, and may be manually extended and retracted.
Also, the auxiliary work for sorting the carrots being transported by the sorting and conveying conveyor 87 and operating the sorting and conveying conveyor 87 at the rear of the left and right sides of the machine frame 1 and behind the sorting and conveying conveyor 87. A boarding step 90 on which a person gets on board is arranged, and an auxiliary work seat 91 is attached to the boarding step 90.

Further, an elevating operation pedal 92 that moves the lifting cylinder 88 up and down to move the conveying terminal end side of the sorting and conveying conveyor 87 up and down is disposed below the conveying path of the sorting and conveying conveyor 87.
And the sorting conveyance part F is comprised by arrange | positioning on the boarding step 90 and the position which the auxiliary worker who seated on the auxiliary | assistant work seat 91 can step on and operate.

  According to the above-described configuration, the lifting / lowering operation pedal 92 for operating the lifting / lowering cylinder 88 is provided at a position where the foot of the auxiliary worker who is seated on the auxiliary work seat 91 can reach, so that the auxiliary worker remains seated on the auxiliary work seat 91. The conveying terminal end side of the sorting and conveying conveyor 87 can be moved up and down, so that the work efficiency is improved and the labor of the operator is reduced.

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

  In the configuration of the sorting and conveying unit F, as described above, the sorting and conveying conveyor 87 conveys carrots to the storage container 97 while discharging earth and sand and remaining leaves downward in the left and right space portions between the conveying bars 144. It is.

  Chain covers 146 and 146 are provided above the front and rear sorting transmission chains 217 and 217 for driving the sorting and conveying conveyor 87, respectively, and the earth and sand falling from above contact the front and rear sorting transmission chains 217 and 217. To prevent that.

  However, from the conveyance end portion 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 tearing of the foliage part in the middle of the conveyance are downward. In some cases, it moves along the path of depression and is discharged, 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 removes the remaining leaves of the carrot and then changes the conveying direction of the remaining leaf processing conveyor 76 in order to guide the carrot to the vicinity of the conveyance start end of the sorting and conveying conveyor 87. The earth and sand, which is mounted obliquely as a reference and falls directly below the end of the remaining leaf processing roller 75, bypasses the chain cover 146 and is placed between the sorting output sprocket 207 on the rear side of the machine body and the sorting transmission chain 217. May get in.

  If earth and sand, especially hard stone, enters between the sorting output sprocket 207 and the sorting transmission chain 217, even if the stone breaks, the timing of the sorting transmission chain 217 rises and the timing at which the sorting output sprocket 207 is not driven. Occur.

  When the sorting transmission chain 217 is lifted, the driving of the sorting and conveying conveyor 87 is temporarily stopped, and the carrots that are being transported in the reaction reversely flow, come into contact with the following carrots, become damaged, and the product value is reduced. Arise.

  In addition, when a deviation occurs in the delivery timing of either one of the front and rear sorting transmission chains 217 and 217, a difference in transport speed gradually begins before and after the sorting transport conveyor 87. The front and rear sorting transmission chains 217 and 217 are connected by a plurality of transport bars 144... And the front and rear sorting output sprockets 207 and 207 have a transport bar 144. Will be loaded.

  As a result, the conveying bar 144 provided between the front and rear sorting transmission chains 217 and 217 is distorted and does not rotate normally. Therefore, these parts must be replaced, and the work is interrupted during that time. There is a problem that it is extremely lowered or misses the harvest time of carrots.

  In order to prevent this problem, the front and rear guard covers 148 and 148 are disposed before and after the front and rear first transport frames 77 and 77 and on the upper surface of the collection belt 133 of the collection conveyor 160, and the front ones are directed to the rear side of the machine body. Install the rear-facing leaning posture and the rear-facing leaning posture toward the front of the aircraft. One end of each of the front and rear guard covers 148 and 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 transport conveyor 87.

  More specifically, it extends to the left and right sides of the machine from the front and rear sorting output sprockets 207 and 207 constituting the sorting and conveying conveyor 87, and the remaining terminal processing of the collecting conveyor 160 and the remaining leaf processing conveyor 76. The earth and sand discharged from the roller 75 are guided by the front and rear guard covers 148 and 148 to the left and right sides of the machine from the sorting output sprockets 207 and 207, and dropped below the sorting and conveying conveyor 87. Sediment is prevented from being caught between the sorting transmission chains 217.

  With the above-described configuration, the sorting transmission chain 217 is lifted from the sorting output sprocket 207, so that the so-called coma shift, which causes a shift in the sending timing of the sorting transmission chain 217, is prevented, and a speed difference occurs between the front and rear positions of the sorting transport conveyor 87. Therefore, it is possible to prevent the sorting and conveying conveyor 87 from being driven due to distortion of the conveying bars 144.

  Thereby, the harvesting operation of the carrot is not interrupted, the work efficiency is improved, and the carrot can be harvested at an appropriate time for harvesting, so that the product value of the carrot is improved. Moreover, it is not necessary to replace parts, and the labor of the operator is reduced.

  In addition, since the front and rear guard covers 148 and 148 are inclined toward the front and rear central portions of the recovery conveyor 160 and the sorting and transporting conveyor 87, the earth and sand placed on the guard covers 148 and 148 are collected and transported by the recovery conveyor 160 and the sorting and transporting. Since it moves to the central part in the front-rear direction of the conveyor 87, it is prevented that the earth and sand moving from the transport terminal end of the recovery conveyor 160 to the transport start end of the sorting transport conveyor 87 approach the front and rear sorting output sprockets 207, 207, Sediment is prevented from being caught between the sorting output sprocket 207 and the sorting transmission chain 217.

  In addition to this, the earth and sand that moves from the remaining leaf processing conveyor 76 to the sorting and conveying conveyor 87 also moves to the center of the sorting and conveying conveyor 87 in the front-rear direction, so that the falling earth and sand fall into the sorting output sprocket 207 and the sorting transmission chain 217. It is prevented from being bitten between the two.

  The front and rear guard covers 148 and 148 are attached when resin rivets are inserted into the front and rear first transport frames 77 and 77 so that the guard cover 148 needs to be replaced when worn. When 148 is pulled up, it is easily removed, so that the guard cover 148 can be easily replaced, and the work efficiency is improved.

  In addition, if the front and rear guard covers 148 and 148 are configured to bend more easily than the other parts by making a cut at the rear end in the transport direction, that is, the front end of the sorting transport conveyor 87, the front and rear guard covers Since 148, 148 can be prevented from becoming a resistance when contacting the transport bars 144 and the receiving bars 145, an extra load is applied to the sorting and transporting conveyor 87, and the durability is prevented from being lowered.

  The front and rear widths of the front and rear guard covers 148 and 148 can prevent earth and sand from falling on the front and rear sorting output sprockets 207 and 207 and the front and rear sorting transmission chains 217 and 217. In order to make it easy to guide the earth and sand toward the part, it is set to about 60 to 90 mm. The guard cover 148 on the front side of the fuselage is less likely to enter the earth and sand than the guard cover 148 on the rear side, so the length as in the above example is not necessary, but if the length is the same for both the front and rear, common parts can be used. Cost reduction.

When the sorting and conveying conveyor 87 is driven from the conveyance terminal end side, the drive system may be configured as follows.
As shown in FIGS. 13 to 15, a rotation shaft 93 for attaching the front and rear hanger arms 95 and 95 is provided through the substantially central portion in the left and right direction of the front and rear sorting transmission cases 200f and 200r.

At a certain position, a protective pipe 222 that is hollow and made of metal or hard resin is provided to prevent adhesion of foreign substances such as soil.

  As described above, the driving force of the sorting and conveying conveyor 87 can be transmitted through the sorting driving gear 220, the sorting counter gears 218 and 218, and the sorting driven gears 219 and 219, so that the transmission loss of the driving force is reduced and the sorting and conveying is performed. The conveyance speed of the conveyor 87 is stabilized, and sorting accuracy and work efficiency are improved.

  Further, since the vertical widths of the front and rear sorting transmission cases 200f and 200r can be prevented from becoming excessively large through the sorting counter gears 218 and 218, the number of parts can be reduced.

  Since the sorting counter shaft 221 is provided on the outer periphery of the rotating shaft 93, the rotating shaft 93 is configured to receive both loads applied to the sorting counter shaft 221. Therefore, the sorting counter shaft 221 is less likely to be damaged. Durability is improved.

  The rotating shaft 93 is a member that is strongly influenced by the weight of the storage container 97 and can withstand a load of 200 kg at a minimum, and actually a higher load. Therefore, a slight load is applied to the sorting counter shaft 221. Even if it is applied, the effect is kept small.

  Further, since the outer periphery of the sorting counter shaft 221 is covered with the protective pipe 222, it is possible to prevent the adhering of foreign matters such as soil and foliage, so that the durability of the sorting counter shaft 221 is reduced by friction or the sorting and conveying conveyor. The driving rotation of 87 becomes unstable, and the sorting accuracy and work efficiency are prevented from being lowered.

  Further, as shown in FIGS. 16 to 18, a rotation shaft 93 for attaching the front and rear hanger arms 95 and 95 is provided through the substantially central portion in the left and right direction of the front and rear sorting transmission cases 200f and 200r.

In FIG. 5, the sorting drive gears 220 and 220 are respectively attached to the front and rear of the sorting transmission shaft 223, and the sorting driving gears 220 and 220 are engaged with the sorting driving gears 220 and 220 on the lower side in the transport direction than the sorting driving gears 220 and 220 on the front and rear sides. The driven gears 219 and 219 are provided via the rotating shafts 206 and 206 of the front and rear sorting output sprockets 207 and 207, respectively. A protective pipe 222 is provided on the outer periphery of the sorting transmission shaft 223. The front and rear rotating shafts 206 and 206 are not connected.

  The sorting drive motor 201 is provided on the front side and outside of the front sorting transmission case 200f, and a sorting driven gear 219 on the front side of the machine body is attached to the output shaft of the sorting drive motor 201. The sorting drive motor 201 is detachable to improve maintenance.

  As shown in FIGS. 19A and 19B, the sorting drive gear 220 and the sorting driven gear 219 include semicircular sorting driving gear components 220a and 220a and sorting driven gear components 219a and 219a. If it is configured to be connected, only the sorting drive gear 220 and the sorting driven gear 219 can be removed during maintenance work or when changing the gear placement position, so there is no need to remove peripheral members. Efficiency is improved.

The front and rear sorting transmission cases 200f and 200r are detachable by moving from the front and rear second transport frames 78 and 78 to the front and rear sides of the machine body.
With the above configuration, the driving force of the sorting and conveying conveyor 87 can be transmitted through the sorting driving gears 220 and 220 and the sorting driven gears 219 and 219, so that the transmission loss of the driving force is reduced and the sorting and conveying conveyor 87 is conveyed. Speed is stabilized, and sorting accuracy and work efficiency are improved.

Next, the structure of the accommodating part G is demonstrated.
As shown in FIG. 2 to FIG. 4 and FIG. 9 to FIG. 11, the rotating shaft 93 is arranged in the front and rear of the machine body on the lower side (left and right other sides) in the transport direction of the second transport frames 78 and 78 before and after the sorting transport conveyor 87. Friction resistors 94 and 94 are pivotally attached to both the front and rear ends of the rotating shaft 93 and outside the second transport frames 78 and 78, respectively.

The friction resistors 94, 94 may be any member as long as it has a strong frictional resistance, such as a disc spring, a spring washer, or a rubber ring.
In addition, the base sides of the front and rear hanger arms 95 and 95 are provided at the front and rear ends of the rotating shaft 93 on the outer side in the front and rear direction with respect to the friction resistors 94 and 94, and the second transport frames 78 and 78 and the hanger arms 95 and 95 are provided. The hanger arms 95, 95 are configured to be movable 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 therebetween.

  As shown in FIG. 9, the hanger arms 95 and 95 are formed with bent portions 95 a and 95 a at the substantially central portion in the left-right direction, and bent into a reverse “h” shape in front view or rear view. Even if the hanger arms 95 and 95 rotate downward when the sorting and conveying conveyor 87 is raised, no gap is generated between the front and rear second conveying frames 78 and 78 and the hanger arms 95 and 95, and the auxiliary work is performed. Even if the person extends his arm toward the transfer terminal of the sorting and conveying conveyor 87, the arm is not caught between the second transfer frames 78 and 78 and the hanger arms 95 and 95, and the safety of the worker is improved. To do.

  Further, since the hanger arms 95 and 95 are positioned in the vicinity of the conveyance end side of the second conveyance frames 78 and 78, the hanger arms 95 and 95 are below the second conveyance frames 78 and 78 regardless of the inclination angle. Therefore, the sorting work space for auxiliary workers is widened, so that sorting accuracy is improved and work efficiency is improved.

  A hanger frame 96 that protrudes in the front-rear direction from the front-rear end of the body of the sorting and conveying conveyor 87 is attached to the ends of the hanger arms 95, 95 in the front-rear direction. A pair of front and rear hanging hangers 98 and 98 for hanging and supporting a storage bag (flexible container bag) 97 for holding the front and rear and left and right are attached to the storage bag (flexible container bag) 97 so as to be rotatable in the left and right direction.

  Further, upside-down inverted U-shaped (saddle-shaped) outer suspension bodies 99a, 99a are welded to the outer end portions of the hanging hangers 98, 98, respectively, and the inner end portions of the aircraft body are downwardly U-shaped. The inner suspension bodies 99b and 99b of the mold are welded, and the suspension hooks 99f, 99f, 99f, and 99f that suspend the containing bag 97 on the outer suspension bodies 99a and 99a and the inner suspension bodies 99b and 99b are movable up and down. Attach to.

  Instead of welding the outer suspension bodies 99a, 99a and the inner suspension bodies 99b, 99b, the outer ends of the hanging hangers 98, 98 are bent into an inverted U shape (saddle shape), and the inner ends of the aircraft It is good also as a structure which can be attached to the hanging hooks 99f, 99f, 99f, and 99f movably up and down by bending a U-shape.

  The hanging hangers 98, 98 have four corners of the housing bag 97 at the front and rear outer suspension bodies 99a, 99a and the front and rear so that the upper opening of the housing bag 97 to be suspended has a substantially rectangular shape in plan view. The inner suspension bodies 99b and 99b are used for suspension.

  Further, when the sorting and conveying conveyor 87 is rotated to the upper limit to be in the stored state, the hanging hangers 98 and 98 are in an orthogonal posture with respect to the machine frame 1, so there is no member that protrudes outside the machine frame 1 during storage. In addition, it is possible to prevent the protruding member from being damaged during storage, and to prevent extra storage space.

  Further, as shown in FIGS. 9 and 10, a visor plate 250 that blocks direct sunlight is attached to the hanger frame 96 in a substantially horizontal posture with the front and rear hanging hangers 98 and 98. The visor plate 250 is rotated together with the hanger frame 96 and is configured to be in a substantially horizontal posture with the hanging hangers 98 and 98 even if the sorting and conveying conveyor 87 is moved up and down.

  With the above configuration, since the visor plate 250 blocks direct sunlight that enters the storage bag 97, it is possible to prevent the ginseng exposed to direct sunlight for a long time from being deflated or cracked due to drying or the like, so the quality of the carrot is reduced. The product value of carrots is improved.

  And lower limit regulation which receives hanger arms 95 and 95 before and behind the conveyance termination part of the 2nd conveyance frames 78 and 78, and the front and back hanger arms 95 and 95 from the attachment position of rotation shaft 93, and regulates downward rotation. The protrusions 100 and 100 are attached. Further, an upper limit regulation that receives the hanger arm 95 on the front side of the machine body and restricts the upper turn at a position outside the second conveyance 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 close to the rotation shaft 93. The protrusion 101 is attached.

  Further, a hole (not shown) in which a female screw is engraved is formed on the rear side or both front and rear sides of the rotating shaft 93, and an adjustment knob 102 in which a male screw (not shown) to be screwed into the hole is engraved. By inserting and rotating the adjustment knob 102 to change the front-rear distance between the second selection frames 78 and 78 and the hanger arms 95 and 95 sandwiching the friction resistors 94 and 94, the frictional resistance is changed. The configuration is as follows.

  If the adjustment knob 102 is provided at the rear end portion of the rotating shaft 93, the auxiliary operator who is on the auxiliary work seat 91 can easily operate. If the adjusting knob 102 is provided at the front end portion of the rotating shaft 93, the control seat 11 is mounted. This makes it easy for the operator to operate and makes it easy to adjust the frictional resistance of the frictional resistors 94 and 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 and on the rear side of the machine body with respect to the rotating shaft 93. A spring 104 for applying an urging force in the front side of the machine body is attached to the shaft. Further, an auxiliary hook 105 is provided at the front end of the machine body on the front side of the spring 104 so as to prevent the slack by hanging the front and rear intermediate parts inside the machine bag 97 that enter the lower part of the sorting and conveying conveyor 87, and the rear side of the slide shaft 103. A slide knob 106 that allows the operator to slide the slide shaft 103 back and forth is attached at the end and outside the second frame 78.

  The slide knob 106 is provided with a hook lever 106a that makes it easy for an operator to operate the slide knob 106 by hand, and the hook lever 106a is directed to the sorting and conveying conveyor 87 side, that is, the inside of the machine body at the base of the hook lever 106a. A biasing torque spring 106b is attached.

  Since the hook lever 106a is brought into contact with the inside of the body of the storage bag 97 during the harvesting operation and urges the inside of the body of the storage bag 97, it is possible to prevent slack from occurring inside the body of the storage bag 97. This prevents the carrot from entering the slack and wastes the storage amount, eliminating the need to frequently replace the storage bag 97 and improving the work efficiency. In addition, when a tube made of a soft material such as rubber is attached to the surface of the hook lever 106a, the carrot stored in the storage bag 97 can be prevented from coming into contact with the hook lever 106a and being damaged. improves.

  In addition, since the visor plate 250 rotates together with the hanger frame 96 and is always in a substantially horizontal posture with the hanging hangers 98 and 98, even if the sorting and conveying conveyor 87 is moved up and down, direct sunlight can enter the containing bag 97. It is difficult to enter, and the product value can be improved by preventing the carrot from being deteriorated, and the visor plate 250 is prevented from obstructing the movement of the hanging hangers 98, 98.

  Furthermore, since the hook lever 106a is pressed against the bottom of the sorting and conveying conveyor 87 by the force of the torque spring 106b when not working (stored), the hook lever 106a is prevented from protruding to the outside of the machine body. The hook lever 106a is prevented from being damaged due to contact during storage, and no extra storage space is taken up.

  If the slide shaft 103 is provided from the rear end portion of the machine body of the sorting / conveying conveyor 87 to the same position as the front / rear intermediate portion or slightly to the front side of the machine body when not operated, 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 machine body. In this case, an operator who is on the control seat 11 can operate the slide shaft 103.

Next, operation | movement of the said accommodating part G is demonstrated.
At the start of the carrot harvesting operation, the sorting / conveying conveyor 87 is lowered to the lowest position in order to minimize the falling distance of the carrot from the conveying terminal end of the sorting / conveying conveyor 87 to the containing bag 97. Further, the four corners of the storage bag 97 are hooked on the suspension hooks 99f, 99f, 99f, 99f provided on the outer suspension bodies 99a, 99a and the inner suspension bodies 99b, 99b of the front and rear suspension hangers 98, 98, respectively. The opening has a substantially rectangular shape in plan view.

  Then, the front and rear hanger arms 95 and 95 are rotated upward until they contact the upper limit restricting protrusion 101, and the front and rear hanging hangers 98 and 98 are inclined upward from the body inner end toward the body outer end. To do. As the hanging hangers 98 and 98 are inclined upward toward the outer side of the machine body, the suspended storage bag 97 is also inclined upward from the inner edge of the machine body toward the outer edge of the machine body. Become posture.

  At this time, among the suspended storage bags 97, the inner side of the machine body from which the carrot is discharged from the transfer terminal end side of the sorting and conveying conveyor 87 is slackened so that the vertical length is shortened, and the outer side of the machine body is hardly slackened so Length increases.

In addition, the accommodation bag 97 shall be comprised flexibly with cloth material, a synthetic fiber, etc.
Further, the outer end of the machine body of the discharge shooter 89 is inserted into the inner end of the storage bag 97, and the inner end of the storage bag 97 is inserted under the transfer end side of the sorting and conveying conveyor 87. Auxiliary hook 105 is hooked in a suspension hole (not shown) formed at a substantially central portion in the front-rear direction. Further, the suspension band 97 i on the inner side of the body of the container bag B is hooked on the suspension band hook 107, and the suspension band 97 o on the outer side of the body is hooked on the suspension band pin 108 on the hanger frame 96.

  The hanger arms 95 and 95 are held in an inclined posture set by the operator due to the frictional resistance of the frictional resistors 94 and 94. However, if the hanger arms 95 and 95 are left unattended, the adjustment knob 102 is rotated. Thus, the frictional resistance force of the frictional resistance bodies 94 and 94 disposed between the second transport frames 78 and 78 and the hanger arms 95 and 95 is adjusted. When the adjustment knob 102 is rotated in the tightening direction, the contact area and the contact pressure of the friction resistors 94 and 94 are increased, the friction resistance is increased, and the hanger arms 95 and 95 are prevented from moving freely. In addition, if it rotates in the loosening direction, the contact area and the contact pressure of the frictional resistance bodies 94 and 94 will decrease, and a frictional resistance force will become weak.

  Further, when the harvesting operation proceeds and the amount of carrots stored in the storage bag 97 exceeds a certain amount, the auxiliary operator steps on the extension side of the lifting operation pedal 92 and extends the lifting cylinder 88 to move the sorting and conveying conveyor 87. Raise the conveyance end side.

  While the sorting and conveying conveyor 87 is moving up, the hanger arms 95 and 95 are lowered because the force that the hanger arms 95 and 95 try to move down exceeds the friction resistance of the friction resistors 96 and 96. The lowering of the hanger arms 95, 95 occurs only while the sorting / conveying conveyor 87 is raised so as to secure a carrot storage space in the storage bag 97.

  When the hanger arms 95 and 95 are rotated downward, the hanging hangers 98 and 98 are rotated with the hanger frame 96 as a fulcrum, the outside of the body of the hanging hanger 98.98 is rotated downward, and the inside of the body is Rotate upward. Since the outer side of the machine body of the storage bag 97 is positioned upward at the stage of installation, there is almost no change in the position, but the inner side of the machine body is pulled upward by the movement of the hanging hangers 98 and 98. Thereby, the slack which had arisen inside the machine body of the accommodation bag 97 is eliminated according to the rising amount.

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

  Further, every time the harvesting operation proceeds and the amount of carrots stored in the storage bag 97 exceeds a certain amount, the transfer terminal end of the sorting transfer conveyor 87 is raised, the hanger arms 95 and 95 are rotated downward, and the storage bag 97 is also rotated. The inside of the fuselage is pulled upward to secure a space for storing carrots in the storage bag 97, and the carrot piles biased toward the inside of the fuselage are destroyed.

  Then, when the sorting and conveying conveyor 87 is rotated upward and the hanging hangers 98 and 98 are in a substantially horizontal posture, the slack on the inside of the machine body of the storage bag 97 is eliminated, and the vertical heights on the inside and outside of the machine body are substantially the same. Become. In this state, since approximately 200 kg of carrots are stored in the storage bag 97, the operator stops traveling of the machine body and lowers the storage bag 97 outside the machine.

At this time, the hanger arms 95 and 95 are configured to contact the lower limit restricting protrusions 100 and 100.
However, if it takes more time to replace the storage bag 97, such as when all the carrots in the field can be harvested in a few meters, the lid that closes the upper opening of the storage bag 97 is suspended. If it is hooked on the outer suspension bodies 99a and 99a and the vertical height from the outside of the body of the storage bag 97 to the vicinity of the central portion in the left-right direction is increased, it can be accommodated if it is several meters (several kg) of carrots. The labor for replacing the bag 97 is saved, and the work efficiency is improved.

Even in this state, there is almost no change in the drop between the transfer terminal portion of the sorting transfer conveyor 87 and the storage bag 97.
When the storage capacity of the storage bag 97 becomes full, the machine body, the pulling and transporting device 24, the sorting and transporting conveyor 87 are stopped, the storage bag 97 is removed from the hanging hooks 99f, 99f, 99f, and 99f, and the hook lever 106a is removed. The auxiliary hook 105 is removed from the storage bag 97 by operating and pulling backward through the slide knob 106. When the hand is released from the hook lever 106a due to the biasing force of the spring 104, the auxiliary hook 105 automatically returns to the sorting / conveying conveyor 87 and the substantially central portion in the front-rear direction of the storage bag 97 at the time of mounting.

  Also, the storage bag 97 containing carrots is placed under its own weight by operating the front down drive motor 115 or the back down drive motor 120 to lower the mounting discharge table 306 forward or backward. 306 slides down, so that when the storage bag 97 is lowered to the front side of the fuselage, the fuselage is retracted, and when the storage bag 97 is lowered to the rear side of the fuselage, the fuselage is advanced so that the storage bag 97 containing about 200 kg of carrots is accommodated. Is taken down from the storage part G and installed in the field.

When the harvesting operation is completed, the hanger arms 95 and 95 are again brought into contact with the upper limit restricting protrusion 101, and the sorting and conveying conveyor 87 is rotated upward to the uppermost position.
With the above-described configuration and operation, there is almost no slack on the outer side of the body of the storage bag 97 from the start of the work to the time of replacement, so it is prevented that carrots enter the slack and reduce the storage capacity of the storage bag 97. The replacement frequency of the bag 97 is reduced, the work efficiency is exchanged, and the labor of the operator is reduced.

  With the conventional method of attaching the storage bag, slack is generated on both sides of the aircraft, so ginseng enters the slack, and even if the storage bag is lifted, the slack cannot be removed. The frequency was high.

  In addition, it was possible to eliminate the slack in the storage bag by moving the sorting transport conveyor up and down, and to secure the storage space, but every time the slack was removed, the operator had to operate the sorting transport conveyor, The efficiency was reduced. In particular, in the case of an auxiliary worker who performs sorting, the sorting accuracy during operation has been reduced.

  And since the drop between the transfer terminal end of the sorting conveyor 87 and the left and right sides of the housing bag 97 is almost constant, the carrot can be prevented from being damaged by the impact of the drop, and the product value of the carrot is improved. To do.

  Further, normally, the rotation of the hanger arms 95 and 95 is regulated by the frictional resistors 96 and 96, and the hanger arms 95 and 95 are configured to rotate downward only while the sorting and conveying conveyor 87 is raised. When the sorting and conveying conveyor 87 is operated in accordance with the change in the amount of ginseng stored in the storage bag 97, the inner sides of the hanging hangers 98 and 98 can be moved upward, so the storage amount of the storage bag 97 is automatically set. Since the slack inside the machine body of the storage bag 97 is automatically eliminated, it is not necessary to move the sorting and conveying conveyor 87 up and down to remove the slack, and the work efficiency is greatly improved.

  In addition, by providing an upper limit restricting projection 101 that determines the upper inclination posture limit 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 containing bag 97 is full.

  In addition, since the upper limit restricting protrusion 101 is provided only on the second transport frame 78 on the front side of the machine body, the upper limit restricting protrusion 101 is within the working range of an auxiliary worker who sorts the carrots being transported by the sorting transport conveyor 87. Since it does not exist, it is possible to prevent the auxiliary worker from colliding or getting caught on clothes, and the burden on the worker is reduced.

  The lower limit regulating members 100 and 100 are also provided on the second transport frame 78 on the rear side of the machine body. However, the lower limit regulating members 100 and 100 are located at the inner end portions of the machine bodies of the hanging hangers 98 and 98, and the normal sorting operation is finished. Since there is no interference with the operation of the auxiliary worker, there is no problem.

  In addition, in order to prevent the operator from forgetting to bring the hanger arms 95, 95 into contact with the upper-stage restricting protrusion 101, forgetting to set can be prevented by writing a note on the second transport frame 78 on the rear side.

  The outer suspension bodies 99a and 99a are provided upward at the outer end portions of the hanger 98 and 98, and the inner suspension bodies 99b and 99b are provided at the inner end portions of the suspension hangers 98 and 98. Since the lowering hooks 99f and 99f are positioned below the hanging hooks 99f and 99f on the outer side of the machine body, when the storage bag 97 is installed, the difference in height between the outer side and the inner side of the body of the storage bag 97 becomes large. Further, ginseng is more difficult to spill from the outside of the body of the containing bag 97.

  Further, when the left and right end portions of the hanging hanger 98 are bent to form the outer suspended body 99a and the inner suspended body 99b, it is possible to reduce the cost because it can be constituted by a single bar.

  Then, the suspension belt 97i provided on the inner side of the container bag 97 is hooked on the suspension belt hook 107 below the sorting and conveying conveyor 87, and the suspension belt 97o provided on the outer side of the housing body is hooked on the suspension belt pin 108 on the hanger frame 96. Thus, the suspension bag 97i, 97o pulls the storage bag 97, so that slack in the storage bag 97 can be reduced.

  Further, by hooking the auxiliary hook 105 into the hole at the substantially central portion in the front-rear direction of the storage bag 97, the slack generated at the substantially central portion in the front-rear direction inside the body of the storage bag 97 can be reduced. It is hard to get into the slack of the room, and sufficient storage space can be secured.

  When the slide knob 106 is pulled to the rear of the machine body, the slide shaft 103 slides to the rear of the machine body and the auxiliary hook 105 is detached from the storage bag 97, so that the storage bag 97 filled with carrots and the sorting and conveying conveyor 87 are transported. Since the auxiliary hook 105 can be removed without entering the narrow space between the lower end portion and the end portion, the work efficiency is improved and the labor of the operator is reduced.

  Further, when the hanger arms 95 and 95 are brought into contact with the upper limit restricting projection 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 outside the machine body. Since the portion is located on the inner side of the end of the body frame 1, the hanging hangers 98, 98 protruding from the body frame 1 do not collide with walls or the like, and the body is prevented from being damaged.

Further, since the end portion of the discharge chute 89 is hung inside the storage bag 97, there is no space where the carrot between the discharge chute 89 and the storage bag 97 can be dropped. Carrots can be prevented from falling and the product value of the carrots is improved.
If the width of the discharge shooter 89 in the longitudinal direction of the machine body is substantially the same as the width of the sorting and conveying conveyor 87 in the longitudinal direction of the machine body, the effect of preventing the carrot from falling is further improved.

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

And a drive motor 310 is provided at the rear end of the male screw rod part and on the second mounting part frame 301 (on the left and right sides of the machine body).

  It should be noted that the front lowering drive motor 305 and the rear lowering driving motor 310 are changed to the front lowering handle 304 and the rear lowering rod 309 by rotating the front lowering rod 304 and the rear lowering rod 309 manually. If the handle (not shown) is provided, the labor of the operator is somewhat increased, but it is not necessary to perform electrical wiring from the battery (not shown), the machine structure is simplified, and the cost is reduced.

  The front lowering rod 304 and the rear lowering rod 309 are used as cylinders (electrical, hydraulic, air, etc.), and an oil feed cable, an electrical harness, an air tube, etc. are connected to the front lowering rod 304 and the rear lowering rod 309. It is good also as a structure to connect. At this time, the front lowering drive motor 305, the rear lowering drive motor 310, the front lowering handle and the rear lowering handle are not necessary.

  A hollow portion that is long in the left-right direction is formed on the front side and the rear side of the placement discharge table 306, and a rear hollow pipe 311r is fixed to the rear hollow portion. On the other hand, a front hollow pipe 311f is inserted into the front hollow portion, which is fixed to the front end portion of the second mounting portion frame 301 with the long side facing the other left and right sides of the machine body. The left and right sides (left side) of the front hollow pipe 311f are left open.

  In addition, the left and right ends of the left and right sides of the front and rear hollow pipes 311f and 311r are closed with caps (not shown) in order to prevent intrusion of foreign matters such as soil and water in the field and cut ends of the foliage. Is desirable.

  Switching solenoids 312f and 312r that draw and move toward the other left and right sides of the machine body are arranged inside the front and rear hollow pipes 311f and 311r and on the left and right sides of the machine body, and slide pins 313f are arranged on the left and right sides of the machine body. , 313r are slidable in the left-right direction of the machine body, and the front and rear slide pins 313f, 313r and the front-rear switching solenoids 312f, 312r move the front and rear slide pins 313f, 313r from the left-right side of the machine to the other side The front and rear lock shafts 315f and 315r are formed by extending and retracting springs 314f and 314r that urge toward each other.

  The sliding range of the front and rear slide pins 313f and 313r is such that when the front and rear switching solenoids 312f and 312r are in the non-actuated state and are pushed out, the one end on the left and right sides of the body is the front and rear hollow pipe 311f. , 311r from the end of the left and right sides of the body to the left and right sides of the body, and from the left and right ends of the left and right sides of the front and rear hollow pipes 311f and 311r to the other side of the body.

When it slides until it protrudes from the left and right one side end, it is configured to enter the holding hole. On the other hand, the rear slide pin 313r protruding from the left and right end portions of the rear hollow pipe 311r is a hollow portion of the hollow rotation shaft 301a which is a rotation fulcrum of the second mounting portion frame 301. It is configured to enter.

The mounting / discharging device 350 is configured as described above.
A state in which the mounting / discharging table 306 of the mounting / discharging device 350 is inclined downward toward the front side of the machine body, and a down-and-posting attitude in which the mounting / discharging table 306 is inclined downward toward the rear side of the body. An operation flow for returning the mounting / discharging table 306 to the receiving position for receiving the bottom portion of the storage container 97 from the state where it is in the forward position and the downward position will be described.

  As shown in FIG. 2, a front down switch 316f and a back down switch 316r are provided on the side of the control seat 11 to perform the front down operation or the back down operation of the table discharge table 306. The front lowering switch 316f and the rear lowering switch 316r may be provided on the second transport frame 78 on the rear side of the machine body that can be operated from the auxiliary work seat 91.

  In addition, when the front / rear indicator 340 is provided in the control unit B, which lights up when the front down switch 316f and the back down switch 316r are operated, and displays whether it is currently in the front down state or the back down state (see FIG. 2), the operator can visually grasp the current rotation operation of the mounting / discharging table 306, and an erroneous operation is prevented.

  When the front down switch 316f is operated, the front switching solenoid 312f is first pulled, and the front switching solenoid 312f and the push spring 314f slide the front slide pin 313f to the left and right sides of the body. By retracting from the holding hole, the front lock shaft 315f is unlocked. Then, when the front lowering drive motor 305 is driven and the front lower telescopic rod 304 is extended in the front-rear direction, the front lowering rotation plate 303 is rotated toward the front side of the machine body. Reference numeral 350 denotes a downward inclined posture in which the mounting / discharging table 306 is directed toward the front of the machine body, that is, a forward and downward posture.

  When the container 97 is lowered to the front side of the machine by sliding on the table discharge table 306, when the front-lowering switch 316f is operated again, the front-lowering driving motor 305 is driven to lower the telescopic rod 304. By contracting, the mounting / discharging table 306 returns to the storage posture for receiving the bottom of the storage container 97 in a posture substantially horizontal to the machine body frame 1. When the mounting / discharging table 306 returns to the storing position and the forward driving motor 305 stops, the front switching solenoid 312f is deactivated, and the front slide pin 313f is attached to the first mounting frame 300. The rotation of the mounting / discharging table 306 is restricted by entering the holding hole and setting the front and rear lock shafts 315f and 315r to the locked state.

  On the other hand, when the rear switch 316r is operated, the rear switching solenoid 312r is first pulled, and the rear switching solenoid 312r and the push spring 314r cause the rear slide pin 313r to move to the left and right sides of the body. By being pulled and slid and retracted from the hollow portion of the rotation shaft 301a into the rear hollow pipe 311r, the rear lock shaft 315r is unlocked. Then, when the rearward drive motor 310 is driven and the rearward retractable telescopic rod 309 extends in the front-rear direction, the rearward downward rotation plate 307 rotates toward the front side of the machine body. Reference numeral 350 denotes a downward inclined posture in which the mounting / discharging table 306 is directed toward the front of the machine body, that is, a forward and downward posture.

  When the container 97 is lowered on the rear side of the machine body by sliding on the mounting / discharging table 306, when the lowering switch 316r is operated again, the lowering driving motor 310 is driven to lower and lower the telescopic rod 119. Is retracted, the mounting / discharging table 306 is returned to the receiving position for receiving the bottom portion of the receiving container 97 in a substantially horizontal position with respect to the body frame 1. Then, when the table discharge table 306 returns to the storing position and the lowering drive motor 310 stops, the rear switching solenoid 312r is deactivated, and the rear slide pin 313r is moved to the rotation shaft 301a. The rotation of the mounting / discharging table 306 is restricted by entering the hollow portion and setting the front and rear lock shafts 315f and 315r to the locked state.

  When operating the front lowering telescopic rod 304 and the rear lower telescopic rod 309 with the front lowering handle and the rear lowering handle, if the front lowering switch 316f and the rear lowering switch 316r are operated, the forward / backward switching is performed. The solenoids 312f and 312r are operated, and after the front and rear switching solenoids 312f and 312r are operated, the front and lower handles are operated to move the loading / unloading table 306 toward the front or rear of the machine body. May be rotated so as to incline downward.

  Alternatively, when the front and rear switching solenoids 312f and 312r are provided with slide levers (not shown) for manually operating the front and rear slide pins 313f and 313r, the forward and lower switch 316f and the rear and lower switch 316r are not provided. Thus, the arrangement of the airframe is omitted to simplify the structure of the airframe, and the cost can be reduced.

  It should be noted that a lateral protection plate 306s that prevents the container 97 from dropping off to the outside of the machine body is provided in the front-rear direction at the left and right ends of the machine discharge table 306 of the mounting / discharging device 350. . If the longitudinal length of the side protection plate 306s is substantially the same as that between the front and rear of the front and rear hollow pipes 311f and 311r, maintenance work inside the front and rear lock shafts 315f and 315r can be easily performed.

  By configuring the mounting / discharging unit H as described above, either the front side or the rear side of the mounting / discharging device 350 can be selected and rotated up and down, so the state of the field and the harvesting operation can be performed. The container 97 can be lowered in a direction suitable for the work conditions such as the number of workers to perform, thereby improving work efficiency and saving labor.

  More specifically, when the storage container 97 is lowered to the front side of the machine body, the operator can stand between the control part B and the placement discharge part H, so that the storage container 97 is completely removed from the placement discharge apparatus 350. When the machine is operated backward to remove it, the operator can support the storage container 97 while operating the machine, allowing one person to work and saving labor.

  On the other hand, when the storage container 97 is lowered to the rear side of the machine body, when the machine body is advanced to completely remove the storage container 97 from the loading / unloading device 350, the carrot harvesting operation can be resumed as it is, thereby improving the work efficiency. To do.

  In addition, when the mounting / discharging table 306 of the mounting / discharging device 350 is lowered to the front side, when the carrot harvesting operation is resumed, it is necessary to avoid the storage container 97 lowered on the farm field and move the body to the ginseng vegetation position. As a result, work efficiency decreases. On the other hand, when the mounting / discharging table 306 of the mounting / discharging device 350 is lowered to the rear side, it is necessary to have at least one worker who advances the machine body and one worker who supports the container 97 so as not to fall down. The labor required for work increases.

  Further, the motor for tilting the mounting / discharging table 306 of the mounting / discharging device 350 downward toward the front or rear of the machine body is separately performed by the front-lowering driving motor 305 and the rear-lowering driving motor 310, thereby making the complicated It is not necessary to use a control device that can be controlled, and the rotation operation of the mounting / discharging device 350 is facilitated, and the operability is improved.

  In addition to the above, a mounting sensor 318 for detecting whether or not the storage container 97 is in the mounting state is provided on the mounting / discharging table 306. The placement sensor 318 may be a pressure-sensitive sensor, a weight sensor, or the like, which is determined based on the weight of the storage container 97. It may be determined on the basis of being extremely close to the mounting discharge table 306.

  When the placement sensor 318 detects that the storage container 97 is placed, the front and rear switching solenoids 312f and 312r and the front and rear solenoids 312f and 312r and the front switch 316f can be operated regardless of which of the forward and backward switch 316f is operated. The lower drive motor 305 and the rear drive motor 310 are configured not to operate.

  However, in the above state, while the container 97 is mounted on the mounting / discharging table 306, the front and rear lock shafts 315 f and 315 r are both regulated to be lower and lowering the mounting / discharging table 306. As a result, the receiving container 97 cannot be lowered out of the apparatus. In order to prevent this, if the control unit B is provided with a sensor stop switch 318a for forcibly stopping the above-mentioned placement sensor 318, the placement discharge table 306 in operation is moved forward and downward, and lowered. When lowering the storage container 97 while restricting the rotation, it is possible to select forward / downward rotation and downward / rearward rotation according to the work conditions, and work efficiency and work safety are improved.

Note that if the sensor stop switch 318a is configured to stop the detection of the placement sensor 318 only while being pressed, forgetting to put the placement sensor 318 is prevented.
Accordingly, the front and rear switching solenoids 312f and 312r are not operated during the rotation operation of the mounting / discharging table 306 of the mounting / discharging device 350, and the locked state and the non-locking state of the front / rear lock shafts 315f and 315r are switched. Therefore, the downward rotation speed of the mounting / discharging table 306 is increased, the posture of the storage container 97 is disturbed, and the stored carrots are scattered around, or the storage container 97 itself is dropped from the storage part G. This prevents the carrot from being damaged due to the impact of falling, and the product value of the carrot from being lowered.

  Further, since the forward drive motor 305 and the rear drive motor 310 are not operated, the front discharge motor 305 and the rear discharge motor 305 are controlled to rotate the placement discharge table 306 in a state where the forward and backward rotation is restricted. Since an overload is prevented from being applied to the lower drive motor 305 and the lower drive motor 310, the front drive motor 305 and the rear drive motor 310 are prevented from being damaged.

  When the front switch 316f or the rear switch 316r is operated while the placement sensor 318 is detecting, a notification sound indicating that the front switching solenoid 312f or the rear switching solenoid 122r is not operating. An alarm device (not shown) such as a buzzer may be provided.

  A lower monitoring sensor 320 that determines the presence or absence of a lower foreign matter is provided on the lower surface of the table discharge table 306. The downward monitoring sensor 320 is preferably a non-contact type distance sensor such as a laser or an ultrasonic wave. However, a contact sensor may be used as long as the contact body is not easily damaged and the detection accuracy is not easily lowered. Good. Alternatively, the detection range of the placement sensor 318 may be expanded below the placement discharge table 306.

  When the lower monitoring sensor 130 detects that there is a foreign object, such as ginseng or a stone that has fallen on the field, or the foot of an operator who is removing the storage container 97, on the lower surface of the mounting discharge table 306, the forward / lower switch 316f Further, even when the rear switch 316r is operated, the front / rear switching solenoids 312f and 312r, the front lower drive motor 305 and the rear lower drive motor 310 do not operate, and the mounting discharge table 306 does not rotate. .

  Further, when the lower monitoring sensor 130 detects a foreign object, when the front-lowering drive motor 305 or the rear-lowering drive motor 310 has already been operated to lower the mounting discharge table 306, the front lower The operation of the drive motor 305 or the rear drive motor 310 is stopped.

  With the above-described configuration, it is possible to prevent the lowered mounting / discharging table 306 from coming into contact with an obstacle such as a stone, and therefore, the mounting / discharging table 306, the front-lowering driving motor 305, and the rear-lowering driving motor 310. The durability of a member that is likely to be subjected to such a load is improved.

Further, since it is possible to prevent the carrots that have fallen on the farm field from being stepped on the mounting / discharging table 306, it is possible to prevent the amount of carrots from being reduced and the product value of the carrots from being lowered.
And since it can prevent that a worker's foot contacts the mounting discharge stand 306, the safety of work improves.

  In addition, even if the descending speed of the mounting / discharging table 306 of the mounting / discharging device 350 of the article of the present application is low and the operator's feet are below the mounting / discharging table 306, It is possible to move the foot to a position where it does not contact the mounting / discharging table 306 with a sufficient margin. Further, when the mounting / discharging table 306 is lowered downward, a play is provided so that the mounting / discharging table 306 rotates upward over several centimeters when a force is applied from below.
