The left and right remaining leaf transport belts 69, 69 are endlessly connected to the left and right residual leaf transport drive pulleys 66, 66, the left and right residual leaf transport driven pulleys 67, 67 and the left and right residual leaf transport tension pulleys 68, 68. By being wound, the remaining leaf transport device 70 that clamps the upper part of the foliage and transports it to the rear of the machine is configured above the leaf discharge transport device 65.

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

  With the above configuration, the left and right positioning drive sprockets 42, 42 are arranged at positions separated from the left and right gaps of the positioning devices 54L, 54R through which the foliage passes, so that the positioning drive sprockets 42, 42 and the Since it can be prevented that the stems and leaves are entangled with the two output shafts 41 and 41 and stop the positioning devices 54L and 54R, the harvesting operation is not interrupted, and the working efficiency is improved.

  Further, by making the alignment drive sprockets 42, 42 smaller in diameter than the alignment alignment driven sprockets 45, 45 and the alignment tension sprockets 47, 47, the alignment alignment drive sprockets 42, 42 are further left and right of the alignment devices 54L, 54R. Since it is separated from the interval, the stem and leaves can be further prevented from becoming entangled with the alignment drive sprockets 42, 42 and the second output shafts 41, 41, and the working efficiency is further improved.

  By providing the left and right biasing springs 50, 50 for biasing the alignment driven sprockets 45, 45, the left and right alignment chains 48, 48 are attached to the left and right alignment chains 48, 48 when the foliage contacts the alignment devices 54L, 54R. Since the loosening that occurs can be absorbed and the alignment chains 48, 48 immediately return to the tensioned state, the alignment devices 54L, 54R can reliably ensure that the ginseng foliage portions even when foliage portions having different diameters pass continuously. And the cutting position of the carrot foliage is properly aligned, and the foliage is appropriately cut, so that there is no need to remove the foliage in a later step, and the work efficiency is improved.

  In addition, the tension of the biasing springs 50, 50 is adjusted by moving the left and right receiving plates 49, 49 in the front-rear direction, so that the difference in the diameter of the foliage depending on the growth status of the ginseng and the variety, or the weather and soil characteristics Since the tension can be changed appropriately according to the working conditions of the work place, etc., the foliage remaining on the ginseng in the later process is removed by properly aligning the cutting position of the ginseng and cutting the foliage. This eliminates the need and improves work efficiency.

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

  When a large load is applied to the left and right positioning devices 54L, 54R when the large diameter foliage passes, the positioning driven sprockets 45, 45 are separated from the movement path of the foliage along the holes 44, 44. In the direction in which the positioning devices 54L and 54R are widened, it is possible to prevent the foliage from being caught in the gaps between the positioning devices 54L and 54R, and stop the body to be bitten. There is no need to remove the foliage and the work efficiency is improved.

  If it is known before the harvesting operation that the ginseng foliage has a large diameter, the alignment driven sprockets 45, 45 are moved in a direction away from the left and right of the left and right alignment devices 54L, 54R. If the left and right intervals of the position aligning devices 54L and 54R on the upstream side in the transport direction are widened, it is possible to prevent the position aligning devices 54L and 54R from biting the foliage, and it is necessary to remove the stuck foliage. And work efficiency is improved.

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

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

  Further, since the attachment and detachment of the guide cover 51 can be performed manually without the need for tools, replacement work can be easily performed.

  Since the guide cover 51 has a U-shape in front view that covers the contact surface between the top and bottom surfaces of the alignment chain 48 and the foliage, a space is created between the guide cover 51 and the alignment chain 48. Since there is no foliage, the foliage is sandwiched between the guide cover 51 and the alignment chain 48, so that the ginseng can be prevented from being aligned at an appropriate cutting position and the foliage can be prevented from being left behind, and the foliage can be removed in a later process. This eliminates the necessity of performing the work, thereby improving the work efficiency, preventing the root of the ginseng from being cut off, and improving the commercial value of the ginseng.

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

  Further, by providing the protruding portion 51c protruding toward the convex R portion 51a, when the alignment chain 48 moves around the alignment alignment driven sprocket 45 or the like in an arc path, the guide covers 51 are connected to each other. Since the projecting portion 51c covers the space formed between the front and rear, the foliage is sandwiched in the space between the front and back of the guide covers 51, so that the carrot is not aligned at an appropriate cutting position and the foliage is left uncut. This eliminates the need for the operation of removing the foliage in the post-process, thereby improving the work efficiency and preventing the ginseng root from being cut off, thereby increasing the commercial value of the ginseng.

  Since the left and right tension plates 53L, 53R are provided in the winding area 18i of the alignment chains 48, 48, the alignment chains 48, 48 are pressed from the winding area 18i, so that the large-diameter foliage passes. At this time, the alignment chains 48, 48 of the portions not pressed by the tension plate 53L or the tension plate 53R can be retracted in the direction of the alignment drive sprockets 42, 42, so that the foliage is moved between the left and right of the alignment devices 54L, 54R. There is no need to stop the body and remove the foliage that has been caught, thereby improving work efficiency.

  Also, by providing the left and right scrapers 55, 55 for scraping off debris such as debris of the foliage and mud attached to the alignment guide bodies 52, 52 which move on the outer periphery of the alignment drive sprockets 42, 52, the foliage is provided. Since it is possible to remove impurities attached to the alignment guide members 52, 52 at a position away from the movement path of the part, the debris of the foliage can be prevented from becoming entangled with each part of the alignment devices 54L, 54R. It is not necessary to remove the debris of the foliage entangled by stopping, and the work efficiency is improved, and the mass of mud is prevented from damaging the root of the carrot, and the commercial value of the ginseng is improved.

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

  Then, the foliage shooter 71 that discharges the leaves (cut foliage) cut from the ginseng by the foliage cutting device 61 to the field will discharge the foliage to the dug side (the side where the ginseng has been harvested). , The ejected foliage falls on the carrot on the undigged side (the side where the ginseng is not harvested), and the ejected leaves fall on the left and right holding conveyor belts 19 and 19 and the left and right driven Since it is possible to prevent the harvesting unit C from being entangled with the pulleys 17, 17 and the like to stop the harvesting operation, the work efficiency is improved, and the discharged leaves falling on the ginseng impair the visibility of the harvested ginseng. Can be prevented.

  Note that the transmission cases 37, 37 are provided with a residual leaf conveying device 70 in order to prevent the foliage transported by the residual leaf transporting device 70 from falling down in the lateral direction of the machine and preventing the foliage from being transported rearward of the aircraft. A left and right leaf receiving plate 177 having substantially the same length in the front-rear direction is provided on each of the left and right. The leaf receiving plate 177 causes the leaf receiving plate 177 to receive the foliage when the foliage portion being transported falls down, so that the foliage portion is transported to the transport terminal portion by the remaining leaf transport device 70, It is discharged to the field through the shooter 71.

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

  As shown in FIGS. 1 to 6, front and rear remaining leaf processing frames 72, 72 are provided below the foliage cutting device 61, and the first remaining leaf is disposed between the left and right sides of the left and right processing frames 72, 72. The processing drive roller 73a is rotatably mounted. Further, a second remaining leaf processing drive roller 73b is rotatably mounted between the front and rear of the left and right other sides of the body of the residual leaf processing frames 72, 72 and below the first residual leaf processing roller 73a. Then, an endless processing belt 74 made of an elastic material such as rubber or urethane is wound around the first remaining processing drive roller 73a and the second remaining processing drive roller 73b endlessly. Further, a ginseng that has been taken over from the foliage cutting part D is attached to the upper part of the ginseng processing belt 74 by attaching a remaining leaves processing roller 75 that sandwiches the remaining leaves at the root of the ginseng together with the remaining leaves processing belt 74 and rotates and cuts the remaining leaves. The left-leaf processing unit E is configured by configuring the left-leaf processing conveyor 76 that conveys the remaining leaves from the outside of the machine body in the left-right inward direction while processing the remaining leaves.

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

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

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

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

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

Since the rotation of the chains 137, 137 stops or slows down, and the selection transmission chains 137, 137 can be prevented from being overloaded, which can be damaged, the amount of ginseng stored in the storage container 97 can be reduced. Even if the transportation end portion side of the selection transportation conveyor 87 is vertically rotated, the transportation speed of the ginseng is not changed, so that the work efficiency is improved and the ginseng selection accuracy is improved.

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

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

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

Attach with the end hanging down.

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

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

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

  Then, the sorting / transporting unit F is configured by disposing the auxiliary worker seated on the auxiliary work seat 91 on the boarding step 90 so as to be able to operate by stepping on the foot.

  According to the above 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 seated on the auxiliary work seat 91 can reach, so that the auxiliary worker can remain seated on the auxiliary work seat 91. The transport end portion side of the sorting transport conveyor 87 can be moved up and down, so that the work efficiency is improved and the labor of the operator is reduced.

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

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

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

  However, from the transport end portion of the collection conveyor 160, the earth and sand falling from the ginseng being transported by the pull-out transport device 24 and the earth and sand adhering to the ginseng that has fallen due to the foliage being cut off during the transport are downward. It may move and be discharged along a falling locus, and the discharge position of the earth and sand may be below the front and rear chain covers 146 and 146.

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

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

  When the sorting transmission chain 137 rises, the drive of the sorting and conveying conveyor 87 is temporarily stopped, and the ginseng being conveyed flows backward due to the recoil, and the carrots come into contact with the following ginseng to be damaged, thereby lowering the product value. Occurs.

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

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

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

  In order to prevent this problem, front and rear guard covers 148 and 148 are provided before and after the front and rear first transport frames 77 and 77 and on the upper surface of the recovery belt 133 of the recovery conveyor 160, and the front one is directed toward the rear of the machine. The rear side should be installed in the forward-downward inclined position toward the front of the aircraft. One end of the front and rear guard covers 148, 148 faces above the transport start end of the recovery conveyor 160, and the other end faces above the transport start end of the sorting and transport conveyor 87.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  When lifting the collection stand 118 with the hanging hangers 98, 98, the postures of the hanging hangers 98, 98 are rotated by about 180 degrees with respect to the posture of suspending the storage bag 97 in the open state.

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

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

  When the adjusting knob 102 is provided at the rear end of the rotating shaft 93 at the rear side of the fuselage, it is easy for an auxiliary worker who is on the auxiliary working seat 91 to operate, and when the adjusting knob 102 is provided at the front end of the rotating shaft 93 at the fuselage, the operating seat 11 is mounted. This makes it easier for the worker who has performed the operation to adjust the frictional resistance of the frictional resistors 94, 94.

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

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

  The hook lever 106a contacts the inside of the body of the storage bag 97 during the harvesting operation to urge the inside of the body of the storage bag 97, so that it is possible to prevent the occurrence of slack inside the body of the storage bag 97. In addition, it is possible to prevent the ginseng from entering the slack and wasting the accommodation amount, and it is not necessary to frequently exchange the accommodation bag 97, thereby improving work efficiency. Further, if a tube made of a soft material such as rubber is attached to the surface of the hook lever 106a, the ginseng stored in the storage bag 97 can be prevented from contacting the hook lever 106a and being damaged, and the commercial value of the ginseng is reduced. 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, 98, even if the sorting / conveying conveyor 87 is moved up and down, direct sunlight enters the storage bag 97. This makes it difficult for the ginseng to penetrate, prevents the carrots from deteriorating, and improves the commercial value, and also prevents the visor plate 126 from hindering the movement of the hanging hangers 98, 98.

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

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

  Then, as shown in FIG. 11, a hanging strap hook 107 for hooking a hanging strap 97i inside the body of the storage bag 97 on the lower side of the sorting and conveying conveyor 87 and on the upper side in the transport direction of the sorting and transporting conveyor 87 than the rotating shaft 93. By attaching a suspension band pin 108 for hanging a suspension band 97o on the outside of the machine body to the upper part of the hanger frame 96 toward the upper side of the machine body, the storage bag hanging device 85 is configured.

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

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

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

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

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

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

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

  When the harvesting operation proceeds and the 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 to extend the lifting cylinder 88 and move the sorting conveyor 87 Raise the transport end side.

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

  When the hanger arms 95, 95 rotate downward, the hanging hangers 98, 98 rotate about the hanger frame 96 as a fulcrum, and the outside of the hanging hanger 98.98 rotates downward, and the inside of the body also rotates. Rotate upward. Since the outer side of the 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 body is pulled up by the movement of the hanging hangers 98, 98. As a result, the slack that has occurred on the inside of the body of the storage bag 97 is eliminated according to the rising amount.

  It should be noted that there is almost no change in the drop between the transport end portion of the sorting transport conveyor 87 and the storage bag 97 due to this operation, and the end of the discharge chute 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 ginseng stored in the storage bag 97 exceeds a certain amount, the transport end of the sorting and transport conveyor 87 is raised, the hanger arms 95 and 95 are rotated downward, and the storage bag 97 is rotated. Is raised upward to secure a space for accommodating ginseng in the accommodating bag 97, and to collapse the ginseng leaning toward the inside of the aircraft.

  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 of the storage bag 97 inside the machine body is eliminated, and the vertical height between the inside and outside of the machine body is substantially the same. Become. In this state, since about 200 kg of ginseng is stored in the storage bag 97, the worker stops traveling of the machine body and lowers the storage bag 97 outside the machine. At this time, the hanger arms 95, 95 are configured to contact the lower limit regulating protrusions 100, 100.

  However, when it is troublesome to replace the storage bag 97, such as when all the ginseng in the field can be harvested within a few meters, the lid that closes the upper opening of the storage bag 97 is hung by hanging the hanger 98, 98. Hooking on the outer hanging bodies 99a, 99a and increasing the vertical height from the outside of the body of the storage bag 97 to the vicinity of the central portion in the left-right direction makes it possible to store ginseng for several meters (several kg) and store it. The work of replacing the bag 97 is omitted, and the work efficiency is improved.

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

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

  Further, by operating the operation handle 116 to lower the mounting table 112 backward, the storage bag 97 in which the carrot is stored slides down the mounting table 112 by its own weight, and the rear side is in the field scene, and the front side is in the mounting table 112. It will be in the grounded state. At this time, by advancing the body, the front side of the storage bag 97 moves along the mounting table 112 and is lowered from the storage section G to the field.

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

  With the above-described configuration and operation, the outside of the body of the storage bag 97 is hardly slacked from the start of work to the time of replacement, so that ginseng is prevented from entering the slack and the storage amount of the storage bag 97 is prevented from being reduced. The frequency of replacement of the bag 97 is reduced, the work efficiency is replaced, and the labor of the operator is reduced.

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

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

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

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

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

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

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

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

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

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

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

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

  Then, when the slide knob 106 is pulled rearward of the machine body, the slide shaft 103 slides rearward of the machine body, and the auxiliary hook 105 is disengaged from the housing bag 97. Therefore, the conveyance of the storage bag 97 filled with carrots and the sorting conveyor 87 is performed. Since the auxiliary hook 105 can be removed without having to enter the hand into a narrow space formed between the terminal portion and the lower portion, work efficiency is improved and the labor of the operator is reduced.

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

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

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

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

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

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

  When the ginseng is harvested in the above configuration, when the ginseng is fully collected in the storage bag 97, the storage table 110 is rotated downward, and the storage bag 97 is removed from the hanging hangers 98, 98. It is necessary to lower the storage bag 97 to the field by advancing the fuselage. Furthermore, it is necessary to attach empty storage bags 97 to the hanging hangers 98, 98.

  If the ginseng is fully stored in the storage bag 97 and cannot be stored any more, the crops being harvested and conveyed will stay in the pull-out conveyance device 24 or the selection conveyance conveyor 87. At this time, in order to prevent ginseng from falling out of the transport path, it is necessary to stop the pull-out transport device 24 and the sorting transport conveyor 87 while exchanging the storage bag 97.

  Therefore, while the accommodating bag 97 is replaced, the carrot harvesting operation is interrupted, and the working efficiency is reduced. In particular, when the storage stage 110 is rotated downward, the body is advanced, and the storage bag 97 is lowered to the field, the harvesting operation cannot be performed despite the advance toward the unharvested ginseng. After lowering the 97, the aircraft must be moved backward to return to the carrot harvesting position, resulting in a significant decrease in work efficiency.

  In order to solve this problem, the storage bag 97 filled with ginseng is removed from the hanging hangers 98, 98, the storage bag 97 is placed on the storage table 110, and the empty storage bag 97 is suspended from the hanging hangers 98, 98. The configuration in which the ginseng discharged from the transport end portion of the sorting transport conveyor 87 can be stored in the storage bag 97 when provided in the storage conveyor 98 will be described.

  As shown in FIGS. 7 to 9 and FIG. 19, the front and rear hanger arms 95 and 95 are configured to be rotatable upward from the hanging posture of the storage bag 97 and to the upper side of the fuselage. 98, 98 are mounted with the empty storage bag 97 extended. When the front and rear hanger arms 95, 95 are turned at the left and right end portions of the body and between the front and rear sides, when the body is rotated downward, the hanger arms 95, 95 rotate toward the storage table 110 side, and the storage bag 97 hangs downward. Is provided. On the other hand, a rotation restricting hook 113 for restricting the rotation of the housing support plate 115 when not in use is provided between the front and rear hanger arms 95, 95 at the left and right ends on the other side of the machine and between the front and rear.

  A biasing member 117 such as a torque spring is provided at the rotation base of the housing support plate 115. When the housing support plate 115 is removed from the rotation restricting hook 113, the housing support plate 115 is moved by the biasing member 117. It is configured to rotate downward.

  When the empty storage bag 97 is mounted on the front and rear hanging hangers 98, 98, the lower end of the storage bag 97 is hooked and the rotation restricting hook 113 is mounted on the storage table 110. A configuration that does not contact the storage bag 97 may be employed. After the storage bag 97 is lowered from the storage table 110 to the field, the lower end of the storage bag 97 is removed from the rotation restricting hook 113, and the ginseng discharged from the sorting and conveying conveyor 87 is moved along the storage support plate 115. The storage bag 97 is moved to the lower end side.

  Thereby, when lowering the storage bag 97 filled with carrots in the field, it is possible to prevent the suspended storage bag 97 from being pulled and falling off the hanging hangers 98, 98, and the work of reattaching the storage bag 97 can be performed. In addition to being unnecessary, the ginseng discharged from the sorting and conveying conveyor 87 is prevented from falling and being damaged at that time and losing commercial value.

  In the above configuration, the rotation angle of the sorting and conveying conveyor 87 is changed to an angle at which the storage bag 97 extends up to the maximum length in the vertical direction, and the front and rear hanger arms 95, 95 are moved to one side of the machine body (upper body). By rotating, the front and rear hanger arms 95, 95 are set to a substantially vertical posture with respect to the body frame 1 or an inclined posture toward the left and right sides of the body.

  As described above, the front and rear hanging hangers 98 and 98 that are in a posture substantially parallel to the front and rear hanger arms 95 and 95 are provided with empty storage bags 97 on the upper opening side. Pull outward. At this time, in order to prevent the empty storage bag 97 from being loosened and covering the storage bag 97 filled with ginseng placed on the storage mounting table 110, a lower portion of the stretched portion of the empty storage bag 97 is provided. Then, the housing support plate 115 protruding from the left and right sides of the machine is exposed.

  The accommodation support plate 115 may have the same width as the left and right widths of the storage bag 97, in other words, the left and right widths of the storage table 110. When the storage bag 95 is rotated downward, the storage bag 97 is placed on the storage table 110. In order to cause this, the lateral width may be configured to be shorter than the lateral width of the storage bag 97 or the storage platform 110.

  Accordingly, when the storage bag 97 is placed on the storage table 110, the slack portion can easily get over the left and right side walls 110b, 110b, so that the rotation angle of the front and rear hanger arms 95, 95 can be changed or the storage angle can be changed. A mechanism for passing the bag 97 without contacting the left and right side walls 110b and 110b by, for example, lifting the bag 97 upward is unnecessary, and the configuration is simplified.

  With this configuration, when the storage stage 110 on which the storage bag 97 full of ginseng is mounted is rotated downward, the storage stage 110 is extended toward the left and right sides of the body and is provided in the front and rear hanging hangers 98, 98 in an open state. Can accommodate the carrots conveyed from the sorting and conveying conveyor 87, so that the time during which the carrot harvesting operation is interrupted can be reduced by removing one of the storage bags 97. Only during installation, the time during which work is interrupted is reduced.

  Further, in order to lower the storage bag 97 to the field, the ginseng can be harvested by the pull-out and transport device 24 when the body is advanced, so that the body is moved backward to the ginseng harvest position after the storage bag 97 is lowered to the field, The process of moving forward and harvesting the ginseng becomes unnecessary, and the work efficiency is further improved.

  After the storage bag 97 is lowered from the storage table 110 to the field, the storage terminal 110 of the sorting conveyor 87 is rotated downward while the storage table 110 is rotated upward. The lower part of the return path 97 is placed on the storage table 110 while shrinking, so that ginseng can be stored with the falling distance from the transport end of the sorting transport conveyor 87 being suppressed.

  The front and rear hanger arms 95, 95 each have a frictional resistor 94 and are configured to rotate downward by the weight of the ginseng stored in the storage bag 97. Even if the forgotten 87 is forgotten, the hanger arms 95 and 95 are rotated downward due to the increase in the weight of the stored ginseng. The bottom part is grounded to the storage table 110.

  At this time, since the storage support plate 115 supports the length of the storage support plate 115 from the opening of the storage bag 97 toward the left and right sides of the machine body, the storage bag 97 becomes slack downward when a small amount of ginseng is collected. This prevents ginseng from being accommodated in order from the lower side of the accommodation bag 97. Thus, the ginseng inside the storage bag 97 can be prevented from falling downward when the front and rear hanger arms 95, 95 rotate downward, so that the carrots can be prevented from hitting each other and being damaged when falling. .

  Also, since the storage bag 97 is in a stretched state at the portion where the storage support plate 115 contacts, the ginseng discharged from the transport end of the sorting transport conveyor 87 moves to the outside of the storage bag 97 using the stretched portion as a shooter. Thus, the ginseng can be reliably moved to the lower side of the storage bag 97.

  Further, the storage bag 97 suspended on the front and rear suspension hangers 98, 98 by the storage support plate 115 is stretched toward the other side of the machine body in a stretched state, so that the storage bag 97 contacts the storage bag 97 on the storage table 110. Therefore, when the storage bag 110 is rotated downward and the storage bag 97 is lowered to the field, the suspended storage bag 97 is prevented from being pulled and dropped from the hanging hangers 98, 98.

  Of the storage bags 97, the ones hanging on the front and rear hanging hangers 98, 98 are accommodated as described above in order to prevent the hanging portion on the lower end side from contacting the accommodation bags 97 on the accommodation mounting table 110. The hanging position is adjusted by the support plate 115 or the lower end is hooked on the rotation restricting hook 113. However, in this method, the storage bag 97 must be extended in advance, and the sorting / conveying conveyor 87 is lowered. In this case, the lower end of the storage bag 97 may not be properly placed on the storage table 110, and the operator may need to adjust the position.

  In order to prevent this, as shown in FIG. 20, hanging strings 114a for hooking the storage bag 97 on a fork of a forklift or a hook of a crane are provided before and after the storage bag 97, respectively. Each of the bases of the suspending strings 114a is attached to 99f..., And a clip 114b is provided at the lower end of the suspending string 114a so as to be hooked on the lower end side of the accommodation bag 97, and extends from the folded state of the accommodation bag 97 before use. It is configured to be held so as not to exist.

  In the above description, the hanging hooks 99f are of, for example, a cannavilar type so that the hanging string 114a does not come off. When the front and rear hanger arms 95 and 95 are rotated downward, the clip 114b is configured to be detached when the weight of the accommodated ginseng is applied, and extends downward on the storage table 110.

  Note that the length of the storage bag 97 can be changed by changing the position where the hanging string 114a is hooked on the hanging hooks 99f... When the storage bag 97 filled with carrots is lowered, The capacity of the storage bag 97 provided on the hanging hangers 98, 98 can be changed in accordance with the expected amount of ginseng harvesting from the storage table 110 to the lowering of the storage bag 97 to the field.
