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 part C from being entangled with the pulleys 17, 17 and the like and hindering the harvesting work, the work efficiency is improved, and the fallen leaves that fall on the carrots hinder the visibility of the carrots to be harvested. Can be prevented.

Next, the remaining leaf processing unit E will be described.
As shown in FIGS. 1 to 3, front and rear remaining leaf processing frames 72, 72 are provided below the foliage cutting device 61, and the first remaining leaves between the front and rear sides of the left and right sides of the remaining leaf processing frames 72, 72. The process 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.
As shown in FIGS. 3 to 10, a transmission shaft 120 for transmitting the driving force of the engine 7 is projected through the lower side of the front and rear remaining leaf processing frames 72, 72 to the rear side of the machine body, and the transmission shaft An output sprocket 121 is pivotally attached to the rear end portion of 120. In addition, an idle sprocket 122 is rotatably mounted above the output sprocket 121 of the remaining leaf processing frame 72 on the rear side of the machine body, and a recovery conveyor described later on the left and right sides of the machine (right side of the machine) from the idle sprocket 122. A recovery input shaft 123a for transmitting a driving force is rotatably mounted on 160, and an input sprocket 123 is mounted on the recovery input shaft 123a.

  Then, a driven sprocket 124 is mounted rotatably on the left and right other sides (left side of the body) of the input sprocket 123 and the output sprocket 121, and spans the output sprocket 121, the idle sprocket 122, the input sprocket 123, and the driven sprocket 124. The transmission chain 125 is wound endlessly. The driven sprocket 124 is attached to a remaining leaf processing output shaft 124a that supplies a rotational driving force to the second remaining leaf processing driving roller 73b.

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

  Further, a second input sprocket 126 is disposed on the rotating shaft of the driven sprocket 124 between the rear leaf processing frame 72 on the rear side and the driven sprocket 124, and the left and right sides of the body are positioned more than the second input sprocket 126. A counter sprocket 127 is rotatably arranged on one side and the lower side. A second driven sprocket 128 is rotatably mounted on the left and right sides and above the counter sprocket 127, and the second input sprocket 126, the counter sprocket 127, and the second driven sprocket 128 are connected to the second sprocket 128. The transmission chain 129 is wound endlessly. The counter sprocket 127 is attached to a sorting / conveying input shaft 127a that supplies a driving force to a sorting / conveying conveyor 87 described later.

  Further, an input spur gear 130a is provided on a rotating shaft (not shown) of the second driven sprocket 128, and an output spur gear 130b is engaged with the input spur gear 130a. The input spur gear 130 a and the output spur gear 130 b are disposed in the transmission gear case 130. An output bevel gear 131a is pivotally attached to the front end of the rotating shaft (not shown) of the output spur gear 130b, and the output bevel gear 131a is connected to the rear end of the rotating shaft (not shown) of the remaining leaf processing roller 75. The input bevel gear 131b that is attached to the shaft is meshed with the input bevel gear 131b.

  With the above-described configuration, the driving power supplied from the engine 7 can be configured in a compact manner so that the transmission path for supplying the recovery conveyor 160, the remaining leaf processing conveyor 76 and the remaining leaf processing roller 75, and the sorting and conveying conveyor 87 can be configured. The front-rear width and the left-right width can be reduced, improving the turning performance of the aircraft and reducing the area required for storage.

Moreover, since the number of parts, such as a sprocket and a transmission chain, can be reduced, cost reduction is achieved.
As shown in FIGS. 3 to 5, the front and rear first transport frames 77 and 77 are arranged in the front-rear direction on the front side of the body relative to the remaining leaf processing frame 72 on the front side of the body and below the alignment devices 54L and 54R. The first transport frames 77 and 77 are arranged at a predetermined interval, and the front and rear second transport frames 78 and 78 are spaced at a predetermined interval in the front-rear direction at the inner end portion (the left and right other end portions) of the first transport frame 77 and 77. In addition, the transfer terminal end side is arranged to be rotatable up and down. The front and rear first transport frames 77 and 77 are T-shaped when viewed from the front (rear), and have an upper inclined portion that is inclined upward toward the other left and right sides from the left and right central portion. And

  Then, a recovery driven roller 132b is rotatably mounted at one end of the left and right sides of the first transport frames 77 and 77 and below the transport surface of the remaining leaf processing conveyor 76, that is, below the upper surface of the remaining leaf processing belt 74. Rotation of the collection input shaft 123a to the left and right other sides of the recovery driven roller 132b and to the position where it can be attached to the recovery input shaft 123a, specifically to the left and right side of the body of the remaining leaf processing roller 75 A collection drive roller 132a to be driven is disposed. Further, the collection belt 133 is wound endlessly across the collection driven roller 132b and the collection drive roller 132a to constitute a collection conveyor.

  The recovery conveyor 160 is disposed below the conveyance path and the alignment devices 54L and 54R of the pulling and conveying device 24, receives carrots whose stems and leaves are cut and dropped on the upper side in the conveying direction than the foliage cutting device 61, and the machine body It is transported from the left and right sides to the other side and taken over by the sorting and transporting conveyor 87. For this reason, the recovery driving roller 133 may be disposed below the recovery driven roller 132, 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. To do.

  A pair of front and rear sorting drive sprockets 134 and 134 mounted on the sorting and conveying input shaft 127a are disposed on the left and right other sides of the body and below the recovery driving roller 133. , 77 are arranged on the left and right other ends of the upper inclined portion of the machine body, and the selected idle sprockets 135, 135 that are pivotally attached to the rotation shaft 79 serving as the rotation fulcrum of the front and rear second transfer frames 78, 78 are arranged. In addition, the front and rear sorting counter sprockets 136 and 136 are located immediately below the sorting drive sprockets 134 and 134 or closer to the left and right sides of the body than the sorting drive sprockets 134 and 134 in the front and rear first transport frames 72 and 72. Are mounted via the rotation shafts 136a and 136a. The rotating shafts 136a and 136a are not connected to each other, and a space is formed between the selection counter sprockets 136 and 136.

  Furthermore, sorting driven sprockets 136b and 136b are rotatably mounted on the left and right other ends of the front and rear second transport frames 78 and 78, the sorting driven sprockets 136b and 136b, the sorting drive sprockets 134 and 134, and the sorting idle. The selection transmission chains 137 and 137 are wound endlessly across the sprockets 135 and 135 and the selection counter sprockets 136 and 136.

  When the sorting counter sprocket 136 is disposed immediately below the sorting drive sprocket 134, the sorting transmission chain 137 from the sorting counter sprocket 136 to the sorting drive sprocket 134 is perpendicular to the ground. When the sorting counter sprocket 136 is arranged closer to the left and right sides of the machine than the sorting drive sprocket 134, the sorting transmission chain 137 from the sorting counter sprocket 136 to the sorting drive sprocket 134 is directed from the left and right sides of the machine toward the other side of the machine. It shall be in a posture that tilts upward.

  When the front and rear first transport frames 77 and 77 are brought into contact with the sorting transmission chains 137 and 137 wound endlessly from below and above, and the front and rear second transport frames 78 and 78 are rotated up and down. In addition, a plurality of tension sprockets 138... That prevent the slack and overload by tensioning the sorting transmission chains 137 and 137 are rotatably arranged.

  Further, a plurality of transport bars 139 are provided between the front and rear sorting power transmission chains 137, 137 for transporting ginseng in the left-right direction at equal intervals, and each of the transport bars 139 is sorted and transported. Receiving bars 140... For preventing carrots from falling down at the upper inclined portion of the conveyor 87 are arranged at equal intervals. Further, the first transport frames 77 and 77 and the second transport frames 78 and 78 are provided with chain covers 141 and 141 that cover the top of the sorting transmission chains 137 and 137, thereby forming a sorting and transporting conveyor 87.

  As described above, since the sorting drive sprockets 134 and 134 are arranged on the left and right sides of the machine and on the lower side of the recovery drive roller 133, the transfer start end of the selection transfer conveyor 87 below the transfer end portion of the recovery conveyor 160. Since the carrots to be transported are prevented from stagnation when taking over, work efficiency is improved, and the stagnation of the carrots is in contact with the stagnation of the carrots. This prevents the product value from deteriorating.

  Further, since the sorting / conveying conveyor 87 is located below the remaining leaf processing conveyor 76, the stagnation of the transfer of carrots from the remaining leaf processing conveyor 76 to the sorting / conveying conveyor 87 is prevented, so that the work efficiency is further improved. , The decline in carrot product value is prevented.

  Since the sorting counter sprocket 136 that bends the sorting transmission chain 137 toward the sorting drive sprocket 134 is disposed immediately below the sorting drive sprocket 134, the orientation of the sorting transmission chain 137 from the sorting counter sprocket 136 toward the sorting drive sprocket 134 is improved. Even if the stone enters from the left-right distance L1 between the transport bars 139 and is transported to the sorting transmission chain 137 and moved to the sorting drive sprocket 134 side because it has a substantially vertical posture with respect to the machine body frame 1, Since the vertical posture portion of the sorting transmission chain 137 prevents the stone from moving upward, it is prevented that the stone is caught between the sorting drive sprocket 134 and the sorting transmission chain 137 and the operation of the sorting drive sprocket 134 is stopped. By sorting and conveying Abrupt stopping of the A 87 is prevented, sorting accuracy and working efficiency are improved.

  In addition, since the stone is prevented from being caught between the sorting drive sprocket 134 and the sorting transmission chain 137, the sorting and conveying conveyor 87 and its constituent members are prevented from being damaged.

  Alternatively, if the sorting counter sprocket 136 is arranged closer to the left and right sides of the machine than the sorting drive sprocket 134, the attitude of the sorting transmission chain 137 from the sorting counter sprocket 136 toward the sorting drive sprocket 134 is changed from the left and right sides of the machine to the other side of the machine. Since it is in the upward inclined posture, the stone in the winding region of the sorting transmission chain 137 moves downward along the upward inclined portion, so that the stone falls downward on the way. And the sorting transmission chain 137 are prevented from being bitten.

  Furthermore, the front and rear sorting counter sprockets 136 and 136 are respectively attached to the rotary shaft 136a, and the front and rear rotary shafts 136a and 136a are not connected, and a space portion is formed between the front and rear. Since there is no member caught when the stone moves, the stone is easily removed, and the sorting and conveying conveyor 87 is prevented from being damaged.

  The idle sprockets 138 that contact the sorting transmission chain 137 are arranged at the lower positions of the upper inclined portions of the first transport frames 77 and 77, so that the surface that does not transport the carrot, that is, the non-working side is tensioned. The amount of ginseng stored in the storage container 97 can be prevented since the rotation of the selection transmission chains 137 and 137 stops and slows down and the occurrence of overload that can damage the selection transmission chains 137 and 137 can be prevented. Therefore, even if the conveying end portion side of the sorting and conveying conveyor 87 is rotated up and down, the ginseng conveying speed does not change, so that the work efficiency is improved and the ginseng sorting accuracy is improved.

  Further, by arranging the transport bars 139 in the left-right direction with a left-right distance L1, the mud soil carried with the carrots and the remaining leaves removed by the remaining leaf processing roller 75 fall from the left-right distance L1 downward. As a result, mud soil and residual leaves entering the storage container 97 are reduced, so that the capacity of the storage container 97 can be filled with carrots, and the frequency of replacing the storage container 97 is reduced, thereby improving work efficiency. To do.

  Furthermore, since the receiving bars 140 are provided at a wider interval than the conveying bar 139, even if the carrots roll on the sorting and conveying conveyor 87, the receiving bars 140 stop the movement of the carrots. Since it is prevented from returning to the conveyance start end portion, work efficiency is improved, and it is possible to prevent the carrot from coming into contact with and damaging the carrot when it falls down, so that the product value of the carrot is maintained.

  The transport bar 139 is formed of a carrot from the recovery conveyor 160 or 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 a rod-shaped metal outer periphery. When taking over, carrots can be prevented from being damaged by the impact of falling, so the product value of carrots is improved.

  Further, when the receiving bar 140 is configured so that rivets or bolts (not shown) are attached to the sorting transmission chain 137 from the opposite side of the conveying surface, that is, the lower side, a rivet or bolt is installed in the winding area of the sorting transmission chain 137. Since the bolt does not protrude, interference with other members is prevented, so that the sorting and conveying conveyor 87 is prevented from being damaged.

  The vertical interval L2 between the sorting counter sprocket 136 and the sorting drive sprocket 134 is configured to be wider than the left-right interval L1 between the transport bars 139. Further, the distance L3 from the outer peripheral edge of the sorting drive sprocket 134 to the central conveyance input shaft 127a is also configured to be wider than the left-right distance L1 between the conveyance bars 139.

  With the above configuration, stones or the like may enter from the left and right distance L1 between the transport bars 139, and may not move downward from the lower side of the sorting conveyor 87 and move to the sorting drive sprocket 134 side by the sorting transmission chain 137. However, since the vertical distance L2 between the sorting counter sprocket 136 and the sorting drive sprocket 134 is larger than the distance L1 between the transport bars 139, stones or the like are sandwiched between the sorting counter sprocket 136 and the sorting drive sprocket 134. Therefore, the sorting / conveying conveyor 87 is prevented from suddenly stopping, and a reduction in work efficiency and damage to the sorting / conveying conveyor 87 are prevented.

  In particular, the sorting transmission chain 137 from the sorting counter sprocket 136 toward the sorting drive sprocket 134 is in a substantially vertical direction with respect to the body frame 1 or an upwardly inclined posture from the left and right sides of the body to the left and right sides. Even if it is transported to the sorting transmission chain 137, it is difficult to move upward in the vertical interval L2, so that stones and the like are further prevented from being caught between the sorting counter sprocket 136 and the sorting drive sprocket 134.

  Furthermore, even if stones or the like may be transported upward to the sorting drive sprocket 134 by the sorting transmission chain 137, the distance L3 between the outer peripheral edge of the sorting drive sprocket 134 and the transport input shaft 127a located substantially at the center. Is larger than the left-right distance L1, and thus it is possible to prevent the rotation of the sorting drive sprocket 134 from being stopped due to a stone or the like being sandwiched between the sorting drive sprocket 134 and the transport input shaft 127a, so that the sorting transport conveyor 87 stops suddenly. This prevents the work efficiency from being lowered and the sorting and conveying conveyor 87 from being damaged.

  At this time, on the left and right sides of the machine from the sorting drive sprocket 134 and the sorting counter sprocket 136, stones that have entered the winding area of the sorting transmission chain 137 and are no longer able to go out remain unreachable. The structure will continue. For this reason, the operator can remove the first conveyance frame 77 on the rear side of the machine body after the harvesting operation is completed, and can remove the stones and the like accumulated at the above-mentioned locations collectively, so that the maintenance performance is improved. Since it takes time to remove all the first transport frames 77, the cleaning window 142 that can be freely opened and closed is located on the left and right sides of the body of the first transport frame 77 on the rear side of the machine more than the sorting drive sprocket 134 and the sorting counter sprocket 136. When it is configured to be disposed at the side of the stone pool, the maintainability is further improved.

  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 rides is arranged, and an auxiliary work seat 91 is attached on the boarding step 90 and at a position near the relay sprockets 80 and 80 of the sorting and conveying conveyor 88.

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.

  As shown in FIGS. 16 and 17, in the first transport frames 77 and 77, in the vicinity of the sorting drive sprockets 134 and 134, it extends between the front and rear and avoids the sorting drive sprockets 134 and 134, and the recovery conveyor. A guard plate 144 for preventing the mud and carrots conveyed from 160 from coming into contact with the sorting / conveying input shaft 127a, particularly the slender side, is disposed. A scraper plate 145 made of a soft material such as rubber is provided below the guard plate 144, and one end of the scraper plate 145 is disposed between the vertical distance L2 between the sorting drive sprocket 134 and the sorting counter sprocket 136. To place.

  With the above configuration, the guard plate 144 can prevent the pebbles and the ginseng slender end from coming into contact with the sorting drive sprockets 134 and 134 and the sorting transport input shaft 127a, so that the rotation of the sorting drive sprockets 134 and 134 stops. Since the sorting and conveying conveyor 87 is prevented from suddenly stopping, the work efficiency is improved and the sorting and conveying conveyor 87 is prevented from being damaged.

  In addition, a scraper plate 145 is provided on the guard plate 144, and one end portion of the scraper plate 145 is disposed between the sorting drive sprocket 134 and the sorting counter sprocket 136 in a vertical interval L2, so that the scraper plate 145 is located above the sorting counter sprocket 136. Since the stone or the like to be moved can be dropped by the scraper plate 145, the stone is further caught between the sorting drive sprocket 134 and the sorting transmission chain 137, and the driving of the sorting conveyor 87 is suddenly stopped. It is prevented from being damaged or damaged.

  Further, as shown in FIG. 20, stone separation plates 146 and 146 are provided inside the front and rear first transport frames 77 and 77 and in the winding region of the selection transmission chains 137 and 137. The stone division plates 146 and 146 are formed in a mountain shape (convex shape) having apexes where the carrots are conveyed, that is, the working transmission transmission chains 137 and 137 are in contact with the lower side. The end portion of 146 is inclined downward toward the inside of the sorting transmission chains 137 and 137.

  With the above configuration, the stone separation plates 146, 146 support the action portion side of the sorting transmission chains 137, 137 from below, so that the sorting transmission chains 137, 137 are at the tops of the chevron of the stone sorting plates 146, 146. They can move in contact with each other, blurring during movement is suppressed, and the conveying posture is stabilized.

  Further, since the stone separation plates 146 and 146 are formed in a mountain shape, even if stones and mud that have entered from the left and right distance L1 of the transport bar 139... Move to the sorting transmission chain 137 and 137 side, Since stones and mud can be moved inward of the sorting transmission chains 137 and 137 along the inclined portion of 146, the stones are caught between the sorting transmission chains 137 and 137 and the sorting drive sprockets 134 and 134. The sorting and conveying conveyor 87 is prevented from suddenly stopping or being damaged.

  As shown in FIG. 21, when the stone separating plates 146 and 146 are provided on the second transport plates 78 and 78 side, the sorting transmission chain 137 extends from the transport start end to the transport end of the sorting transport conveyor 87. , 137 move in a stable posture, and it becomes difficult for stones and mud to enter the winding region of the selection transmission chains 137, 137.

Next, the structure of the accommodating part G is demonstrated.
As shown in FIGS. 2 and 6 to 10, the rotary shaft 93 penetrates in the longitudinal direction of the machine body on the lower side (left and right other side) in the conveyance direction of the second conveyance frames 78 and 78 before and after the sorting and conveying conveyor 87. Friction resistors 94, 94 are pivotally attached to the front and rear ends of the rotating shaft 93 and outside the second transport frames 78, 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 FIGS. 6, 8, and 9, the hanger arms 95, 95 have bent portions 95a, 95a 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 shape toward the upper side, that is, the shape bent in the reverse “to” shape in the front view or the back view, even if the hanger arms 95 and 95 rotate downward when the sorting and conveying conveyor 87 is raised, Even if the auxiliary worker extends his arm toward the transfer terminal portion of the sorting transfer conveyor 87, the second transfer does not occur between the front and rear second transfer frames 78 and 78 and the hanger arms 95 and 95. The arms are not caught between the frames 78 and 78 and the hanger arms 95 and 95, and the safety of the operator is improved.

  Further, since the hanger frames 95 and 95 are positioned in the vicinity of the conveyance end side of the second conveyance frames 78 and 78, the hanger frames 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.

  9, the suspension hangers 98, 98 are removed from the hanger frame 96, the outer suspension bodies 99a, 99a are hooked on the front and rear ends of the hanger frame 96, and the inner suspension bodies 99b, 99b are described later. When the sorting conveyor 87 is turned upward by being hooked on the support protrusion 119 provided at the outer end of the recovery table 118 to be recovered, the recovery table 118 is pulled up to the hanging hangers 98 and 98 and automatically accommodated. Since the posture can be made substantially orthogonal to the frame 1, it is not necessary to lift the collection table 118 manually, and the labor of the operator is reduced.

  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.

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

  Further, as shown in FIGS. 6 to 8, a visor plate 126 that blocks direct sunlight is attached to the hanger frame 96 with the front and rear hanging hangers 98 and 98 in a substantially horizontal posture. The visor plate 126 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, the visor plate 126 blocks the direct sunlight that shines into the storage bag 97, so that it is possible to prevent the ginseng exposed to direct sunlight for a long time from being deflated or cracked due to drying, etc. 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 126 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 / 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 126 is prevented from obstructing the movement of the hanging hangers 98, 98.

  Further, 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. Sometimes the hook lever 106a is prevented from being damaged by contact, and an extra storage space is not 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.

  Then, as shown in FIG. 10, a hanging band hook 107 that hooks a hanging band 97 i inside the body of the storage bag 97 below the sorting and conveying conveyor 87 and on the upper side in the conveying direction of the sorting and conveying conveyor 87 than the rotating shaft 93. Is attached to the upper part of the hanger frame 96 and the hanging band pin 108 for hooking the hanging band 97o on the outer side of the machine body is arranged facing the upper side of the machine body, whereby the accommodation bag hanging device 85 is configured.

The suspension bands 97i and 97o on the outside of the machine body are members for hanging the accommodation bag 97 containing carrots on a forklift or hoist.
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-back 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.

  Further, by operating the operation handle 116 to lower 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 that time, the machine body is retracted, and when the storage bag 97 is lowered to the rear side of the machine body, the machine body is moved forward so that the storage bag 97 containing about 200 kg of carrots is lowered 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. The carrots are more unlikely 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.

Hereinafter, another embodiment of the ginseng harvester will be described.
As shown in FIGS. 22 and 23, left and right support frames 150 and 150 that are long in the vertical direction are provided on the rotating frame 20 and below the conveyance path of the pulling and conveying device 24. The upper sides of the left and right support frames 150 and 150 are formed in a square shape that is widely separated toward the lower side when viewed from the front (rear).

  The transmission case 22 is provided with rear end portions of left and right front transmission cases 151 and 151 that transmit driving force to the front side of the machine body, and the front end portions of the front transmission cases 151 and 151 are disposed on the left and right support frames 150. , 150 and holding drive pulleys 152, 152 that are rotated by receiving a driving force from the front transmission cases 151, 151. Further, left and right holding driven pulleys 153 and 153 are rotatably mounted on the front side of the left and right support frames 150 and 150 and above the tail cutting device 35, and the left and right holding driven pulleys 153 and 153 are connected to the holding drive. Left and right holding tension pulleys 154 and 154 are rotatably mounted between the front and rear of the pulleys 152 and 152.

  The left and right support frames 150 and 150 are arranged in a square shape when viewed from the front (rear), but the holding drive pulleys 152 and 152, the holding driven pulleys 153 and 153, and the holding tension pulleys 154 and 154 are respectively The rotating shaft (not shown) is inserted in a direction perpendicular to the support frames 150 and 150.

  Further, the holding driving pulleys 152 and 152, the holding driven pulleys 153 and 153, and the holding tension pulleys 154 and 154 are held in contact with the carrots that are being transferred and transferred from the pulling and conveying device 24 to the alignment devices 54L and 54R. The conveyor belts 155 and 155 are wound endlessly to constitute the holding and conveying device 156.

  The holding and conveying device 156 brings the left and right holding and conveying belts 155 and 155 into contact with the carrot, prevents the carrot being conveyed from being shaken by vibrations of the airframe, etc., and reliably transfers the carrot to the alignment devices 54L and 54R. It is a device for.

  When harvesting carrots from late autumn to early winter, the foliage is often withered in the cold, i.e., withered frost, and the foliage is shredded by impact when it touches the alignment devices 54L and 54R. Ginseng may fall. For this reason, in this embodiment, the recovery conveyor 160 is arranged below the alignment devices 54L and 54R to receive the carrot that has fallen and return it to the transport path.

  On the other hand, in this embodiment, since the holding and conveying device 156 continues to contact the carrot from the left and right up to the end portions of the alignment devices 54L and 54R, even if the foliage portion is cut off, the carrot is left behind. Therefore, it is not necessary to remove the remaining leaves from the carrot on the sorting / conveying conveyor 87 or after the work is completed, and the sorting accuracy and work efficiency are improved.

  Even if the foliage portion does not break, the holding and conveying device 156 conveys the carrot in a posture up to the front of the remaining leaf processing conveyor 76, so that the foliage cutting device 61 cuts the foliage portion and the remaining leaf processing conveyor. Since the falling position of the carrot falling to 76 can be stabilized, the remaining leaves are easily removed.

  In addition, the upper side of the left and right support frames 150, 150 has a C shape, so that even if the carrot is bent or bifurcated, the carrot is between the left and right of the left and right holding and conveying belts 155, 155. It is possible to prevent clogging, and it is not necessary to interrupt the harvesting operation to remove ginseng, thus improving the work efficiency.

  Furthermore, by providing the front end portion of the holding and conveying device 156 immediately after the tail cutting device 35 and at an upper position, the holding and conveying device 156 is disposed in a posture that easily receives the carrot that has passed through the tail cutting device 35 and has been slightly tilted backward. Therefore, it is prevented that the carrot is bounced back to the holding conveyance device 156 and the conveyance is stagnated, and the work efficiency is improved.

  As shown in FIG. 24, a clutch mechanism 147 is provided on the sorting / conveying input shaft 127a, the clutch mechanism 147 is connected to the lifting operation pedal 92 with a wire 148, and when the lifting operation pedal 92 is stepped on, the connecting wire 148 becomes the clutch mechanism 147. The clutch mechanism 147 may be “disengaged” by acting on the above.

  With the above configuration, the amount of carrots stored in the storage container 97 is increased, and when the work of increasing the capacity of the storage container 97 by raising the transport end portion side of the sorting transport conveyor 87 is performed, the lifting operation pedal Since the driving of the sorting and conveying conveyor 87 stops while stepping on 92, the operator can operate the sorting and conveying conveyor 87 without being distracted by the carrot sorting operation. , Sorting accuracy is improved.

  Note that a clutch operation pedal 149 different from the lifting operation pedal 92 is provided, the clutch operation pedal 149 and the clutch mechanism 147 are connected, and when the operator steps on the clutch operation pedal 149, the clutch mechanism 147 is turned off. Then, when the conveying speed of the sorting and conveying conveyor 87 is disturbed or abnormal noise is generated, the driving of the sorting and conveying conveyor 87 can be stopped immediately. If the cause of the damage enters, it can be removed before serious damage occurs.

  Further, when it is desired to take time for sorting, if the operator steps on the clutch operating pedal 149, the worker can perform the sorting operation by stopping only the sorting conveyor 87, and the sorting accuracy is greatly improved. Since it is not necessary to stop the harvesting work, work efficiency is improved.
