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 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-described effect is further improved by reliably removing the debris of the foliage and dirt such as mud from the alignment guide bodies 52 and 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 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. A processing roller 73a is rotatably attached. A second remaining leaf processing roller 73b is rotatably mounted between the left and right sides of the left and right sides of the remaining leaf processing frames 72, 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 roller 73a and the second remaining leaf processing 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. 2 to 5, 6, and 9, the front and rear first transport frames 77 and 77 are arranged at a predetermined interval in the front-rear direction on the front side of the machine body and below the remaining leaf processing conveyor 76. The first transport frames 77 and 77 have inner end portions (the other end portions on the left and right sides of the main body) and the outer front and rear second transport frames 78 and 78 with a predetermined interval in the front and rear direction and the transport end portion side. It is arranged so that it can rotate up and down. The front and rear drive sprockets 79 and 79 are rotatably attached to the left and right side ends of the first transport frames 77 and 77, respectively, and the front and rear relays are connected to the left and right end portions of the first transport frames 77 and 77, respectively. The sprockets 80, 80 are rotatably mounted at positions below the drive sprockets 79, 79, and the front and rear driven sprockets 81, 81 are respectively rotatable at the left and right other ends of the second transport frames 78, 78.

Further, a plurality of transport bars 84 made of synthetic resin such as plastic or rubber for transporting carrots on the transmission chains 82, 82 are rotatably attached.
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.
Then, mud and leaf dust adhering to the conveying bar 84 of the sorting and conveying conveyor 87 in the upper side of the sorting and conveying conveyor 87 in the conveying direction, that is, in the winding region of the transmission chains 82 and 82 on the first conveying frames 77 and 77 side. The cleaning plate 120 for removing impurities such as root waste is provided in the same upward inclined posture as the inclined posture of the first transport frames 77 and 77 and is detachable. Further, the upper and lower ends of the cleaning plate 120 in the conveying direction are bent downward, and a plurality of V-shaped cleaning slits 120a are formed in the front-rear direction. The V-shaped cleaning slit 120a has a shape in which a central protrusion is positioned on the upper side in the transport direction and widens in the front-rear direction toward the lower side in the transport direction.

  Further, the cleaning plate 120 is disposed at a position where the cleaning plate 120 contacts and pushes up the conveying bar 84. That is, the cleaning plate 120 is not positioned directly under the transmission chains 82 and 82.

  The cleaning slits 120a are formed by burring, and convex portions (not shown) are formed on the non-contact surface side. In addition, when a cleaning blade 120 is formed on the upper end of the cleaning slit 120a in the conveying direction and within the thickness of the cleaning plate 120, and a contaminant such as leaf dust is caught on the cleaning slit 120a, When the transport bars 84... Advance toward the lower side in the transport direction, the contaminants are cut by the cutting body 121.

  In addition, oil supply tanks 122 and 122 for supplying lubricating oil to the transmission chains 82 and 82 are provided on the second conveying frames 78 and 78 and above the transmission chains 82 and 82, respectively. An opening is formed at the lower end of the oil tank 122, and a ball 123 having the same diameter as that of the opening is housed, and a spring 124 for biasing the ball 123 downward is provided. Further, an oil feed button 125 for changing the flow rate of the lubricating oil by increasing / decreasing the internal pressure in the oil tank 122 is disposed above the oil tank 122.

  When the balls 123 come into contact with the transmission chains 82 and 82, the balls 123 are pushed upward to supply the lubricating oil to the transmission chains 82 and 82. If the oil supply tank 122 is detachably configured, the lubricating oil can be supplied only when necessary, so that the lubricating oil can be saved. In addition, since the extra lubricating oil is not supplied to the transmission chains 82 and 82, it is prevented that the lubricating oil falls into the field and contaminates the soil and carrots, so that environmental preservation and carrot quality are preserved. .

  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 ascending / depressing pedal 92 a and a descending step pedal 92 b that move the lifting and lowering cylinder 88 up and down to move the conveying terminal end side of the sorting and conveying conveyor 87 up and down are arranged 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 configuration, since the relay sprockets 80 and 80 are arranged below the drive sprockets 79 and 79, the section of the sorting and conveying conveyor 87 where the relay sprockets 80 and 80 are arranged from the drive sprockets 79 and 79 is the machine body. By tilting about 2 to 5 degrees inward (toward the left and right sides of the machine) and taking a posture that is substantially parallel to the remaining leaf processing conveyor 76, no matter where the carrot falls from the remaining leaf processing conveyor 76, the remaining leaf processing Since the drop between the conveyor 76 and the transfer start end of the sorting transfer conveyor 87 is substantially the same, carrots can be prevented from being damaged by the impact of the drop, and the commercial value is improved.

  Further, in the winding region of the transmission chains 82, 82 on the first transport frame 77, 77 side, which is the upper side in the transport direction of the sorting transport conveyor 87, dirt such as mud, leaf waste, root waste, etc. adhering to the transport bars 84. By providing the cleaning plate 120 for scrubbing things, it is possible to remove the contaminants adhering to the transport bars 84... During the harvesting operation and drop them onto the field, which reduces the time and labor required for cleaning after the operation. Therefore, maintainability is improved.

  Further, since a plurality of cleaning slits 120a... Are formed on the cleaning plate 120 from the upper side to the lower side in the transport direction, it becomes easy for the foreign matter attached to the cleaning plate 120 to fall downward. It is possible to prevent things from accumulating and deteriorating the cleaning performance or adhering impurities to the conveying bars 84.

  Furthermore, since the cleaning plate 120 is disposed at a position where the transport bars 84 are pushed upward, the mud soil adhering to the transport bars 84 due to vibration and contact resistance when the transport bars 84 get over the step is easily dropped. In addition, mud is less likely to remain, reducing the time and labor required for cleaning work and improving maintainability.

  In addition, when the cleaning plate 120 and the transport bar 84 are in close contact with each other, the leaf waste and root waste entangled with the transport bar 84 enter the cleaning slit 120a, so the leaf waste and root waste are drawn by shearing force. The impurities are less likely to remain on the sorting and conveying conveyor 87, and the time and labor required for the operation of removing the impurities after the work is completed are reduced.

  Further, when the transport bar 84 contacts the cleaning plate 120, the transport bar 84 rotates, so that it becomes easy to remove the entangled matter entangled with the transport bar 84 with the rotational force, thereby further reducing the time and labor required for cleaning. The

  And by forming the cleaning slit 120a ... in a V shape with the center located on the upper side in the transport direction, the carrots with one end narrow and the other end thick are transported to the lower side in the transport direction by the rotation of the transport bar 84 ... Since it moves to the front side or the rear side of the body as it is done, it is prevented that the carrots are fixed in one place, the operator can easily see the carrots, and the sorting accuracy is improved.

In addition, since the straight conveying bars 84 are prevented from entering the cleaning slits 120a, the sorting and conveying conveyor 87 is not suddenly stopped, and the work efficiency is improved.
Furthermore, since the cleaning plate 120 is configured to be detachable, it is possible to remove the adhering contaminants by removing the cleaning plate 120 during cleaning, so that it is possible to reliably remove the contaminants and improve maintainability.

  Then, the cleaning slits 120a are formed by burring, and the convex portions are formed on the non-working surface (back surface) of the cleaning plate 120, so that the transport bar 84 contacts the flat surface of the cleaning plate 120. The bars 84 are less likely to wear due to friction, and durability is improved.

  In addition, since the contaminants that have entered the cleaning slit 120a are easily caught by the projecting portion protruding downward, they are more easily removed during the conveyance, and the time and labor required for the cleaning operation are reduced.

  Further, since the saw blade-shaped cut body 121 is formed at the upper end of the cleaning slit 120a in the transport direction and within the thickness of the cleaning plate 120, foreign matters may not be separated from the transport bar 84. However, since it will be torn if it catches on the cutting body 121, it will prevent that the conveyance bar 84 ... progress is prevented and work efficiency will improve.

  In addition, even if the foliage portion left uncut by the carrot enters the cleaning slit 120a, the foliage portion is torn off when the ginseng is conveyed with the foliage portion touching the cut body 121. The progress of ... is prevented and the work efficiency is improved, and it becomes difficult for the foliage to remain in the carrot, and the work of removing the foliage from the carrot after harvesting is omitted, so the labor of the worker Is reduced.

  Further, by providing the oil supply tanks 122, 122 on the upper portions of the transmission chains 82, 82, the lubricating oil can be supplied to the transmission chains 82, 82 even while the carrot is harvested. Since the conveyor 87 is prevented from moving, work efficiency is improved and durability is improved.

  Further, since the lubricating oil leaks only when the ball 123 comes into contact with the transmission chains 82 and 82 and is pushed up, an excessive amount of lubricating oil is prevented from being discharged to the transmission chains 82 and 82. Therefore, it is possible to save the lubricating oil and prevent the lubricating oil from falling into the field and contaminating the soil and ginseng, thereby preserving the environment and the quality of the carrot.

  Further, when the ball 123 is pressed against the transmission chains 82 and 82, the lubricating oil is supplied while the transmission chains 82 and 82 are moving, so that the lubricating operation can be automatically performed and the maintenance performance is improved. Will improve.

  When the oil supply button 125 for changing the flow rate of the lubricating oil is provided in the oil supply tank 122, the operator presses the oil supply button 125 and presses the oil supply button 125 when the amount of leakage of the lubricating oil is small or poor. Since the internal pressure can be increased and the leakage amount of the lubricating oil can be increased, the lubricating oil is sufficiently supplied to the transmission chains 82 and 82, and the operation of the sorting and conveying conveyor 87 can be kept smooth.

  In addition, the auxiliary operator is seated on the auxiliary work seat 91 by providing the ascending pedal 92a and the lowering pedal 92b for operating the elevating cylinder 88 at positions where the feet of the auxiliary worker sitting on the auxiliary work seat 91 can reach. It is possible to move the transfer terminal end side of the sorting and conveying conveyor 87 up and down, and the work efficiency is improved and the labor of the operator is reduced.

  Further, by providing the ascending step pedal 92a and the descending step pedal 92b, the auxiliary worker can operate the vertical movement of the sorting / conveying conveyor 87 with his / her feet, and concentrate his hand on the sorting operation of the carrots being conveyed. Therefore, the sorting accuracy is improved, and it is possible to prevent the hand from being pinched or cut by the constituent members of the sorting and conveying conveyor 87, and the safety of the work is improved.

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-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 ascending pedal 92a and extends the elevating cylinder 88 to extend the conveying terminal portion of the sorting conveying conveyor 87. Raise the 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. 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.
As shown in FIGS. 2, 16 and 17, front and rear support plates 109 and 109 are attached to the rear side of the left and right other sides of the body frame 1 in the left and right direction of the body, and are attached to the outer end portions of the front and rear support plates 109 and 109. The mounting portion frame 110 is attached so as to be rotatable in the left-right direction of the machine body with the left-right rotation shaft 110a as a rotation fulcrum. A vertical rotation shaft 111a is provided at the rear lower portion of the mounting portion frame 110, and a bottom portion of the storage bag 97 suspended from the front and rear hanging hangers 98, 98 is placed on and supported by the upper portion of the vertical rotation shaft 111a. A mounting table 112 is attached so as to be rotatable up and down.

  Further, a rear support plate 113 is provided at the left and right other side ends of the mounting portion frame 110 described above, and the lower end portion of the rotating plate 114 is disposed at the left and right other side ends of the vertical rotating shaft 111a. A telescopic rod 115 is attached between the upper part of the pivoting plate 114 and the upper part of the rear support plate 113.

  Further, an operation handle 116 for extending and retracting the telescopic rod 115 is attached to the rear end of the telescopic rod 115, and a fall prevention plate 117B for preventing the storage bag 97 from dropping on the left and right sides and the rear side of the mounting table 112. , 117L, 117R are attached to form a recovery table 118. A support protrusion 119 that hooks one end of the hanging hangers 98 and 98 during the folding operation of the recovery table 118 is attached to the outer end of the recovery unit 118 (the right end of the unit).

  Out of the fall prevention plates 117B, 117L, and 117R, a discharge opening 117s for discharging water and foreign matters is formed on the left side of the machine body, that is, on the lower side of the left fall prevention plate 117L disposed on the inside of the machine body. When water is turned to the body frame 1 side, water and impurities fall into the field from the discharge opening 117s.

  Then, a torque spring 110b is attached to the left / right pivot shaft 110a so as to constantly urge the collection base 118 upward and hold it in an upwardly inclined posture. When the weight of the carrot stored in the storage bag 97 increases, the machine body automatically. It is set as the structure rotated below until it becomes a substantially horizontal attitude | position with respect to the flame | frame 1. FIG.

The storage bag suspending device 85 and the collection stand 118 constitute a placement discharge unit H.
The telescopic rod 115 has a thread groove on the surface of one bar, and a thread groove on the inner surface of the other hollow bar. The thread grooves of the bars are aligned with each other and rotated by the operation handle 116 to expand and contract. However, in this case, the operation handle 116 may be replaced with a switch or a lever.

Hereinafter, another embodiment of the ginseng harvester will be described.
As shown in FIG. 18, the transmission chain 82, 82 on the lower side of the winding region is placed on the upper side in the conveyance direction of the sorting and conveying conveyor 87, that is, below the transmission chain 82, 82 on the first conveyance frame 77, 77 side. The tension sprockets 127, 127 before and after being pushed up are arranged so that the vertical position can be changed. The vertical movement mechanism of the front and rear tension sprockets 127, 127 is a single rotation in which an L-shaped adjustment long hole 128 is formed in the first transport frame 77 on the rear side of the machine body, and the tension sprockets 127, 127 are axially attached. The end of the shaft 127a on the rear side of the machine body protrudes from the adjustment slot 128 to the rear of the machine body, and a return spring 129 for biasing the rotary shaft 127a upward is provided.

  When the rotary shaft 127a is not operated, the tension sprockets 127 and 127 move upward to push up the transmission chains 82 and 82, and the lower end of the conveying bar 84 on the upper side of the winding area is placed below the winding area. It is set as the structure which contacts the upper end part of the conveyance bar 84 ... of a side. Further, when the end of the rotating shaft 127a is moved downward along the L-shaped adjustment slot 128 and the rotating shaft 127a is hooked on the notch 128a, the tension sprockets 127, 127 are moved downward and the winding area The lower transport bars 84 are separated from the upper transport bars 84 of the winding area.

No member is provided below the tension sprockets 127 and 127 and before and after the first transport frames 77 and 77.
With the above configuration, when the transmission chains 82, 82 are pushed upward by the tension sprockets 127, 127, the lower ends of the upper conveying bars 84 ... of the winding area and the upper ends of the lower conveying bars 84 ... of the winding area come into contact. Therefore, dirt such as mud adhering to the transport bars 84 due to the impact of the contact can be shaken off, so that the time and labor required for the cleaning work are reduced and the maintainability is improved.

  In addition, because the shearing force generated when the conveying bars 84 rub against each other, the leaf waste and root debris wound around the conveying bars 84 can be scraped and dropped downward, so that foreign matters stay on the sorting and conveying conveyor 87. Is prevented, the time and labor required for the cleaning work are reduced, and the maintainability is improved.

  Then, by moving the tension sprockets 127, 127 downward and switching them to a state where they do not contact the transmission chains 82, 82, it is possible to make the conveyance bars 84 ... not contact each other when it is not necessary to remove impurities. Occurrence of vibration and transmission errors due to contact resistance is prevented, and carrots are transported stably.

  Furthermore, since no members are provided below the tension sprockets 127 and 127 and before and after the first transfer frames 77 and 77, the falling contaminants fall into the field without being caught by anything. Work becomes easier and maintainability improves.

  As shown in FIG. 19, the drive sprockets 79, 79 may be replaced with drive cam sprockets 130, 130 so that vibration is intermittently applied to the upper side in the transport direction of the sorting transport conveyor 87. At this time, the diameters of the drive cam sprockets 130 and 130 are smaller than the diameters of the relay sprockets 80 and 80 and the driven sprockets 81 and 81.

  The first sorting frames 77, 77 are provided with fixed tension sprockets 131, 131 before and after being energized in contact with the lower side of the winding region of the transmission chains 82, 82 from above. Further, front and rear tension arms 132 and 132 that are rotatable up and down are provided, tension springs 133 and 133 that bias the front and rear tension arms 132 and 132 upward are provided, and end portions of the front and rear tension arms 132 and 132 are provided. The front and rear rotary tension sprockets 134 and 134 are rotatably provided to constitute automatic tension mechanisms 135 and 135. The rotating tension sprockets 134 and 134 are brought into contact with the lower side of the transmission chains 82 and 82 so that the influence of the change in the tension of the transmission chains 82 and 82 due to the rotation of the drive cam sprockets 130 and 130 is affected by the sorting and conveying conveyor 87. This is a configuration that minimizes the influence on the drive.

  Further, idle sprockets 136 and 136 for holding the transmission chains 82 and 82 from above are provided above the relay sprockets 80 and 80, and the vibrations of the drive cam sprockets 130 and 130 from the vicinity of the center of the sorting and conveying conveyor 87 to the rear end. It is set as the structure which is not transmitted.

  An input sprocket 137 is provided between the left and right of the relay sprocket 80 and the driven sprocket 81 on the rear side of the machine body, and the input sprocket 137 is configured to be movable in the left-right direction. Further, a blower fan 138 that generates wind by the rotation of the input sprocket 137 is attached to a rotating shaft 137 a that is pivotally attached to the input sprocket 137. The blowing direction of the blower fan 138 is configured to be directed from the rear side to the front side.

  With the above configuration, vibrations can be intermittently generated between the left and right of the drive cam sprockets 130 and 130 and the relay sprockets 80 and 80 in the sorting and conveying conveyor 87, so that dirt such as mud is shaken off. Therefore, the time and labor required for cleaning are reduced, and maintainability is improved.

  Further, the automatic tension mechanism 135, 135 is configured to always apply a constant urging force to the transmission chains 82, 82, thereby suppressing the change in the tension of the transmission chains 82, 82 due to the rotation of the drive cam sprockets 130, 130. Therefore, it is possible to prevent the transmission chains 82 and 82 from being detached when the conveying speed of the sorting and conveying conveyor 87 is changed or when the tension is low, and the work efficiency is improved.

  Since the fixed tension sprockets 131 and 131 contact the transmission chains 82 and 82 from above, the upper conveying bar 84 and the lower conveying bar 84 can be brought close to each other. Since the contaminants are reliably dropped by the contact between the transport bars 84, the maintainability is improved.

  Furthermore, since the drive cam sprockets 130 and 130 are configured to have a smaller diameter than the relay sprockets 80 and 80 and the driven sprockets 81 and 81, high-frequency vibrations can be generated, so that foreign matters are removed from the transport bar 84. It becomes easy.

  In addition, since the vibration is not transmitted between the right and left of the relay sprockets 80 and 80 and the driven sprockets 81 and 81, it is possible to prevent the ginseng to be sorted from jumping up and down, so that the sorting operator can increase the size of the ginseng. Since it becomes easier to identify the sheath shape, the sorting accuracy is improved.

  Further, by providing the blower fan 138 in the transport path of the sorting and transporting conveyor 87, it is possible to remove dust and dust that could not be dropped by vibration by blowing away with the wind. Is prevented, and the sorting accuracy is improved.

  In addition, since the wind direction of the blower fan 138 is directed from the rear side to the front side of the machine body, the dust and dust that are blown away do not hit the sorting operator seated on the auxiliary work seat 91, and the labor of the worker is reduced. The

  Further, since the input sprocket 137 with the blower fan 138 attached thereto can be moved in the left-right direction, the operator can easily move the blower fan 138 to a position where it is desired to remove impurities and dust. improves.
