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.

  The left and right tension springs 50 and 50 for tensioning the alignment driven sprockets 45 and 45 are provided, so that the left and right alignment chains 48 and 48 are generated when the foliage comes into contact with the alignment devices 54L and 54R. Since the slack can be absorbed and the alignment chains 48 and 48 immediately return to the tensioned state, the alignment devices 54L and 54R ensure that the 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 tension 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 tensioned by the tension springs 50, 50 move toward the conveyance path of the foliage portion, so that the small diameter foliage portion 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 hindered, thereby improving the work efficiency and preventing the visibility of the carrots harvested by the fallen leaves falling on the carrots. Can be prevented.

Next, the remaining leaf processing unit E will be described.
As shown in FIGS. 1, 2, 9, and 10, front and rear remaining leaf processing frames 72 and 72 are provided below the foliage cutting device 61, and the front and rear remaining leaf processing frames 72 f and 72 r are outside the body ( The first remaining leaf processing roller 73a is rotatably attached between the front and rear of the left and right sides. In addition, a second remaining leaf processing roller 73b is rotatably mounted between the front and rear of the remaining leaf processing frames 72f and 72r (the left and right other sides) 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, the remaining leaf processing plate 75 is attached to the upper side of the machine body in the winding region of the remaining leaf processing belt 74, and the inner end portion of the machine body of the remaining leaf processing plate 75 is bent downward. Further, a transmission gear box 76 for transmitting the power of the engine 7 is provided near the end of the remaining leaf processing frame 72r on the rear side of the fuselage, near the end of the left and right other sides of the remaining leaf processing frame 72f on the front side of the aircraft. The base of the support arm 77a is attached to the base. Further, one side of a spring 77b that expands and contracts in response to an overload is attached to the end of the support arm 77a, and a support plate 77c having an L shape in plan view is attached to the other side of the spring 77b. Then, between the support plate 77c and the gear box 76, a residual leaf processing roller 78 for sandwiching and cutting the residual leaf remaining at the root of the carrot together with the residual leaf processing plate 75 is rotatably attached, and the foliage cutting portion The remaining leaf processing section E is configured by configuring the remaining leaf processing conveyor 79 that conveys the remaining leaves of carrots inherited from D from the outer side of the machine body to the left and right sides.

The remaining leaf processing conveyor 79 is inclined by about 2 to 5 degrees from the left and right sides of the machine body to the left and right sides.
Due to this inclined posture, the dropped carrot moves to the lower side due to the drive of the remaining leaf processing belt 74 and the inclination of the remaining leaf processing conveyor 79, so that the movement of the carrot does not stop on the remaining leaf processing conveyor 76. There is no need to move the carrots that were stopped during the work, improving work efficiency. Further, since the residual leaf processing conveyor 76 is slightly inclined (about 2 to 5 degrees), the residual leaf processing conveyor 79 is in relation to the ground even when the aircraft is inclined in the left-right direction 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 79 and does not move in the direction opposite to the conveying direction of the remaining leaf processing conveyor 79. There is no need to return it and work efficiency is improved.

  With the above configuration, the remaining leaf processing plate 75 and the remaining leaf processing roller 78 constituting the remaining leaf processing conveyor 79 tear off the remaining leaves of the carrots cut and removed by the foliage cutting device 61. The work of cutting the remaining leaves can be omitted, and the work efficiency is improved.

  Further, the remaining leaf processing belt 74 constituting the remaining leaf processing conveyor 79 is made of an elastic body such as rubber or urethane, so that the remaining leaf processing belt is removed even if the ginseng falls by being 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.

  Then, by attaching the front end portion of the remaining leaf processing roller 78 to the support plate 77c, if the remaining leaf processing roller 78 bites a hard object such as a stone and is overloaded, it depends on the strength of the overload. The spring 77b contracts and moves to the support arm 77a side, and the support plate 77c and the front side of the remaining leaf processing roller 78 are retreated to the lower side in the transport direction of the remaining leaf processing conveyor 79. It is possible to prevent the rotation shaft of the leaf processing roller 78 from being damaged, and the durability of the remaining leaf processing conveyor 79 is improved and the service life is prolonged.

  In addition, since it is difficult for stones or the like to enter between the remaining leaf processing roller 78 and the remaining leaf processing belt 74, it is possible to prevent the stones or the like from breaking the remaining leaf processing belt 74. Improves longevity.

  Further, since the inner end of the machine body of the remaining leaf processing plate 75 is bent downward, when the remaining leaf processing roller 78 moves backward, a gap is generated between the remaining leaf processing roller 78 and the remaining leaf processing plate 75, so that a stone or the like However, it is possible to prevent the remaining leaf processing belt 74 from being broken, and the durability of the remaining leaf processing belt 74 can be improved and last longer.

A second support plate 81 that is L-shaped in rear view is attached to the back of the remaining leaf processing plate 75 (lower side of the machine body) in the vicinity of the moving fulcrum 80a. A second spring 82 that expands and contracts in response to an overload is attached between the second support plate 81 and the rotating portion 80, and when the rotating portion 80 is overloaded, the rotating portion 80 rotates downward. It is good also as a structure which retreats.

  In the above configuration, when an overload is applied, the front side of the remaining leaf processing roller 78 is retracted to the lower side in the transport direction according to the strength of the overload, and the rotating unit 80 is below the fuselage according to the strength of the overload. Since the clearance is sufficient to pass through even if a relatively large stone or the like is bitten, the transmission gear box 76 and the remaining leaf processing belt 74 can be further prevented from being damaged, and the transmission gear box 76 and the remaining leaf can be prevented. The durability of the processing belt 74 is improved and it lasts longer.

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

The front and rear second transport frames 84 and 84 are attached in a substantially straight line on the inner end of the first transport frame 83 and 83 (the left and right other end) and on the outer side. The front and rear drive sprockets 85 and 85 are rotatably attached to the outer ends of the first transport frames 83 and 83, respectively, and the front and rear relay sprockets 86 and 86 are attached to the inner ends of the first transport frames 83 and 83, respectively. The front and rear driven sprockets 87 and 87 are rotatably attached to the left and right other ends of the second transport frames 84 and 84, respectively.

  Further, the front and rear transmission chains 88, 88 are wound around the drive sprockets 85, 85, the relay sprockets 86, 86, and the driven sprockets 87, 87, respectively, in an endless manner. Further, a plurality of transport plates 90 for carrying carrots on the transmission chains 88, 88 are rotatably attached, and a metal material or a hard resin material is used every few of the plurality of transport plates 90. By attaching transport lugs 91 that are covered with an elastic body such as rubber or vinyl chloride, a sorting transport conveyor 92 that transports carrots from the left and right sides of the machine body to the left and right sides is configured.

  It should be noted that if the surface of the transport plate 90 is coated with a soft member such as rubber, the impact of carrot falling when taking over from the remaining leaf processing conveyor 79 can be reduced, and the carrot is prevented from being damaged, and the product value of the carrot is improved. To do. Further, the conveying lugs 91 may be made of only a relatively hard elastic material such as rubber.

  Further, a lattice-like takeover shooter 93 that receives carrots falling during the conveyance of the drawing and conveying device 24 is provided below the drawing and conveying route R of the drawing and conveying device 24 and outside the conveying start end of the sorting and conveying conveyor 92. It is attached so as to be tiltable toward the inner side of the machine body and rotatable in the vertical direction. Then, the inner end portion of the takeover shooter 93 is brought close to the upper part on the transfer start end side of the sorting and conveying conveyor 92, and the inner end portion of the takeover shooter 93 is rotated in the vertical direction every time the conveying lugs 91 contact. The configuration is as follows.

  Then, on the rear side of the left and right sides of the machine body frame 1 and on the rear side of the machine body with respect to the sorting and conveying conveyor 92, the sorting operation of the carrots being transferred by the sorting and conveying conveyor 92 and the movement and installation of the container 107 described later are performed. By placing the boarding step 94 on which the auxiliary worker gets on and attaching the auxiliary work seat 95 on the boarding step 94 and in the vicinity of the relay sprockets 86 and 86 of the sorting and conveying conveyor 92, the sorting and conveying section F Composed.

  According to the above-described configuration, every several transport lugs 91 are provided on the transport plates 90, so that the portion of the sorting transport conveyor 92 that is inclined upward from the outer side of the machine body to the inner side of the machine body (the first transport frame). 83, 83 in the width of the left and right sides), the transport lugs 91 can prevent the carrots from falling toward the lower side (outside the machine body) of the sorting and transporting conveyor 87. It is possible to prevent sticking and the product value is improved.

In addition, since it is possible to prevent the same carrot from riding on the sorting and conveying conveyor 92 for a long time, the work efficiency is improved.
And since the conveyance lug 91 was configured by covering the surface of the metal plate with an elastic body such as rubber, the carrot does not bend due to an impact when it comes into contact with the conveyance lug 91, while the carrot hits the conveyance lug 91. Can be prevented from falling, improving the product value of carrots.

  Furthermore, by covering a metal material (such as an iron plate) or a hard resin material (such as an acrylic plate) with an elastic body, the carrot can be prevented from being damaged when contacting the conveyance lug 91, and the product value of the carrot. Will improve.

  Further, when the transport plates 90 are moved to the non-conveying action side of the sorting transport conveyor 92, the upper ends of the transport lugs 91 are directed downward, so that the upper ends of the transport lugs 91 are bottom of the sorting transport conveyor 92 (not shown). 2), it can act as a scraper to scrape off the foliage and mud and other foreign matter adhering to the bottom plate of the sorting and conveying conveyor 92. Accumulation is prevented and maintainability is improved.

  Further, a take-off shooter 93 that takes down the carrot that falls during the transfer and moves it to the sorting and conveying conveyor 92 is provided in a downwardly inclined posture from the outside of the machine body to the inside of the machine body, below the drawing and conveyance route R of the drawing and conveying device 24. This makes it possible to return carrots that have fallen during transport to the transport path without being scattered outside the machine frame 1 or outside the machine, improving the efficiency of harvesting work and requiring the operator to collect the carrots that have been dropped. The labor of the operator is reduced.

  Further, the inner end of the machine body of the takeover shooter 93 is positioned above the conveyance start end of the sorting and conveying conveyor 92, and the takeover shooter 93 is rotated up and down each time the conveyance lugs 91 contact the inner end of the takeover shooter 93. As a result, the carrot placed on the takeover shooter 93 can be dropped every time it is turned up and down, so that the carrot is prevented from staying in the takeover shooter 93 and the work efficiency is improved.

  Furthermore, by arranging the boarding step 94 on which the auxiliary worker gets on the rear side of the sorting and conveying conveyor 92, the auxiliary worker can board and move on the traveling machine body. Does not need to move on its own, greatly reducing labor.

  Since the auxiliary work seat 95 on which the auxiliary worker is seated is arranged in the boarding step 94, the auxiliary worker can sit on the auxiliary work seat 95 and perform a sorting operation and the like. This reduces fatigue and improves the work efficiency and reduces the labor of the worker.

  The moving rollers 101 and 101 are not only in the vicinity of the front and rear ends between the first cradle frame 100a and the second cradle frame 100b, but also between the front and rear of the first cradle frame 100a and the second cradle frame 100b. A plurality of them may be provided.

  Then, a portal stopper arm 102 is attached to the first cradle frame 100a and the second cradle frame 100b so as to be rotatable in the longitudinal direction of the machine body, and an end of a pivot shaft of the portal stopper arm 102 is attached. A first interlocking arm 103 that rotates in a direction approximately 180 degrees opposite to the rotation direction of the stopper arm 102 is attached to the portion. Further, a second interlocking arm 104 is rotatably attached in the front-rear direction of the fuselage on both sides of the rotating shaft of the moving roller 101 on the rear side of the second cradle frame 100b. An interlocking rod 105 is attached between the upper end of 104 and the lower end of the first interlocking arm 103. In addition, by attaching an engagement plate 106 protruding to the front side of the machine body to the front end portions of the first cradle frame 100a and the second cradle frame 100b, the carrot discharged from the transport end portion of the sorting transport conveyor 92 is provided. A receiving base 108 on which the receiving container 107 is placed is formed.

Further, there are empty ends at the left and right ends of the rotating shaft of the moving roller 101 on the rear side of the machine body, which is pivotally attached to the rear end of the first cradle frame 100a and the second cradle frame 100b. A spare container mounting table 109 on which one or more containers 107 are mounted is mounted so as to be rotatable in the longitudinal direction of the machine body, and between the support frame 96 on the rear side of the machine body and the left and right sides of the spare container platform 109 on the left and right sides of the machine body. At the same time, a traction spring 109a is attached which pulls the spare container mounting table 109 to the front side of the machine body and maintains a rearward rising inclination posture.

  A plurality of pivot shafts are provided on the front side of the machine body relative to the cradle 108 and on the other left and right sides of the machine body frame 1 or to a position where the pivot shafts do not come into contact with the cradle 108. The left and right sides of the storage frames 110, 110 are provided, and the other left and right sides of the storage frames 110, 110 are provided at substantially the same interval as the left and right intervals of the first receiving frame 100a and the second receiving frame 100b. The left and right storage pulleys 110 and 110 are provided with left and right drive pulleys 112 and 112 rotatably attached to the drive rotary shaft 111 on the front end side, and are driven at the left and right other ends of the drive rotary shaft 111. A drive motor 113 for supplying force is attached. Further, left and right driven pulleys 115 and 115 attached to the driven rotary shaft 114 in the vicinity of the rear end portions of the left and right storage frames 110 and 110 are rotatably attached, and the front and rear of the driven rotary shaft 114 and the drive rotary shaft 111 are rotated. In between, left and right tension pressure pulleys 117 and 117 attached to one or more tension pressure rotating shafts 116 are attached.

  Then, the transfer belts 118 and 118 are wound around the drive pulleys 112 and 112, the driven pulleys 115 and 115, and the tension pressure pulleys 117 and 117, respectively, and the drive motor 113 is attached to the driven rotary shaft 114. By providing a contact type or proximity type switch 119 to be driven, a container transfer device 120 that moves the container 107 toward the front of the machine body is configured.

  Further, by attaching extension plates 121 projecting toward the rear of the fuselage to the rear ends of the storage frames 110 and 110, respectively, a container carrier 122 capable of mounting a plurality of containers 107 full of carrots is formed. . The container carrier 122 rotates about 90 degrees in the left-right direction of the body with a rotation shaft (not shown) provided on the body frame 1 as a rotation fulcrum.

By combining the cradle 108 and the container carrier 122, the accommodating portion G is configured.
With the above configuration, the support frames 96 and 96 of the cradle 108 are inclined at a predetermined angle (30 to 45 degrees) with respect to the horizontal state during harvesting work, and the container 107 is placed on the tilted cradle 108. Since the opening of the container 107 is inclined so as to face the conveyance end of the sorting and conveying conveyor 92, the distance between the conveying end of the sorting and conveying conveyor 92 and the bottom of the container 107, that is, the carrot fall distance can be reduced. As a result, carrots can be prevented from being damaged by the impact of falling, and the product value of carrots is improved.

  Further, since the support frames 96 and 96 and the support arms 97 and 97 are connected to each other by gas dampers 99 and 99 that are extendable and have a constant or substantially constant reaction force in the extension direction, the container 107 contains ginseng and has a weight. Since the cradle 108 is automatically lowered with the increase in the number of workers, there is no need for the operator and auxiliary workers to lower the cradle 108 manually, thereby reducing the labor of the worker and reducing the sorting and conveying conveyor 92. Since the fall distance of the carrot falling from the conveyance terminal part hardly changes, the carrot is prevented from being damaged by the impact of the drop, and the commercial value is improved.

  Further, when the container 107 loaded with carrots is moved to the container carrier 122 from the cradle 108 that has been lowered, the gas dampers 99 and 99 are stretched with a constant or substantially constant reaction force to rotate the support frames 96 and 96 upward. Since it is automatically moved back to a predetermined tilting posture (at a tilt of 30 to 45 degrees), it is not necessary for the operator or auxiliary worker to lower the cradle 108 manually, thereby reducing the labor of the worker. In addition, when the container 107 is removed, the cradle 108 does not rise rapidly, and the cradle 108 with momentum is prevented from hitting an auxiliary worker and being injured, thereby improving work safety. To do.

  And by providing the stoppers 98 and 98 which restrict | limit the downward rotation of the support arms 97 and 97, the receiving stand 108 does not fall below predetermined height, but it is easy to match | combine the height with the container carrier 122. The container 107 is smoothly moved from the cradle 108 to the container carrier 122, and the work efficiency is improved.

  Further, the engagement plates 106 and 106 are provided at the front end portion of the cradle 108, and the extension plates 121 and 121 are provided at the rear end portion of the container carrier 122, so that the cradle 108 is lowered to substantially the same height as the container carrier 122. Then, the engagement plates 106 and 106 come into contact with the extension plates 121 and 121 so that the lowering of the cradle 108 is restricted, and the heights of the cradle 108 and the container carrier 121 can be adjusted more accurately. Therefore, the movement of the container 107 from the cradle 108 to the container carrier 122 becomes smoother, and the work efficiency is further improved.

  Furthermore, since at least two or more moving rollers 101, 101 are provided on the cradle 108, the container 107 moves with a relatively light force from the front or the rear, so that the auxiliary worker can board the boarding step 94. Alternatively, if the user sits on the auxiliary work seat 95 and pushes the container 107 forward by hand or kicks it with his / her foot, the worker 108 can be easily moved from the cradle 108 to the container carrier 122, thereby reducing the labor of the operator. At the same time, work efficiency is improved.

Since the stopper arm 102 is provided on the front side of the cradle 108, it is possible to prevent the container 107 containing the carrot from moving to the container carrier 122 without permission. The first working arm 103 is attached to the same rotation shaft as the stopper arm 102, and the second working arm 104 and the spare container are mounted on the rotation shaft of the moving roller 101 on the rear side of the machine body. The mounting base 109 is pivotally attached, and the first interlocking arm 103 and the second interlocking arm 104 are connected by the interlocking rod 105, so that the auxiliary worker can lower the container 107 placed on the spare container mounting base 109 downward. When pushed down, the spare container stand 109 pivots downward and the second interlocking arm 104 pivots backward, via the interlocking rod 105. Then, the first interlocking arm 103 rotates to the rear of the machine body and the stopper arm 102 rotates to the front to release the restriction. Therefore, the auxiliary worker can push the empty container 107 forward to load the carrots. Since the empty container 107 can be moved to the container carrier 122 and placed on the cradle 108 at the same time, the sorting / conveying conveyor 92 is not stopped or an extremely short time (about 10 to 20 seconds). About) If the sorting and conveying conveyor 92 is stopped, the container 107 can be moved and installed, so that the work efficiency is remarkably improved.

  In addition, as shown in FIGS. 2 and 3, since the auxiliary work seat 95 is located on the side of the spare container platform 109 on the other side of the machine body, the auxiliary worker is fully loaded with carrots without standing from the auxiliary work seat. The container 107 can be moved and the empty container 107 can be installed, so that the labor of the operator can be reduced and the work can be concentrated.

  When the container 107 passes over the stopper arm 102, the stopper arm 102 rises and returns to the restricted state that restricts the movement of the container 107 forward of the machine body. Therefore, the empty container 107 placed on the cradle 108 Since it can prevent moving to the front side of a machine body, work efficiency improves.

  Further, a spare container mounting table 109 is arranged at the rear of the receiving table 108, and a traction spring 109a is provided between the auxiliary container mounting table 109 and the support frame 96 of the receiving table 108 on the rear side of the machine body, thereby providing a spare container mounting table. Since the pedestal 109 is pulled toward the front of the machine body by a traction spring and is in a rear-upward inclined posture, when the container 107 placed on the cradle 108 is moved to the container carrier 122, the empty container 107 is automatically formed. Since the container is moved from the spare container placing table 109 to the receiving table 108, when the container 107 is replaced, the replacement can be performed without stopping the driving of the sorting and conveying conveyor 92, so that the work efficiency is improved.

  In addition, the auxiliary worker seated on the auxiliary work seat 95 pushes out (kicks out) the rear part of the empty container 107 placed on the auxiliary container stand 109 while being seated on the auxiliary work seat 95 to the front side of the aircraft. Thus, the container 107 storing the carrots placed on the cradle 108 can be pushed by the empty container 107 and moved toward the container carrier 122, so that the container 107 can be reliably replaced and the cradle 108 can be replaced. The time lag when the empty container 107 is placed in the car is reduced, and the carrot is prevented from falling to the field from the transport end of the sorting transport conveyor 92 that is not stopped. The product value of ginseng can be prevented from being damaged, and it is not necessary to manually collect the ginseng after harvesting. Effort of the person is reduced.

  And by configuring the container transfer device 120 that automatically conveys the container 107 toward the front side of the machine body from the front side of the machine body of the container carrier 122 to a position slightly ahead of the rear end of the machine body, When the container 107 full of carrots is sent to the container carrier 122, the container transfer device 120 is activated to move the container 107 a predetermined distance toward the front side of the machine body, so that an operator or an auxiliary worker manually moves the container 107. There is no need to move it, improving work efficiency.

  Further, since the space between the empty container 107 placed on the cradle 108 and the container 107 full of carrots moved to the container carrier 122 is automatically opened, the container 107 from the cradle 108 to the container carrier 122 is opened. Since the movement is not hindered by the container 107 already placed on the container carrier 122, the auxiliary worker can push out the container on the cradle 108 with a constant force, and the work efficiency is improved and Labor is reduced.

  Further, a switch 119 for operating the drive motor 113 of the container transfer device 120 is provided in the vicinity of the rear side of the container carrier 122, and this switch 119 is a proximity switch or a contact switch, so that the container 107 pushed out from the cradle 108 is Since the drive motor 113 is driven and the container transfer device 120 operates only while passing over the switch 119 provided on the rear side of the container carrier 122, it is possible to save energy without consuming extra energy when unnecessary. Can be planned.

  Further, since the drive motor 113 is driven only while the container 107 passes above the switch 119, the container 107 moves the container carrier 122 by about one container 107 by one drive, so the container 107 first moves to the container carrier 122. It is possible to prevent the discharged container 107 from staying at the front end of the container transfer device 120 and applying a load to the container transfer device 120 and the drive motor 113, preventing damage to the container transfer device 120 and the drive motor 113, and improving durability. To do.

  The container carrier 122 can be rotated in the left-right direction with the rotation axis as a rotation fulcrum, the support frames 96, 96 of the receiving base 108 can be rotated up and down, and the spare container mounting table 109 can be moved in the front-rear direction. By being able to rotate, the spare container mounting table 109 is rotated forward toward the upper side of the receiving table 108, the receiving table 108 is rotated upward toward the upper side of the sorting and conveying conveyor 92, and the container carrier 122 is moved. By rotating toward the fuselage frame 1, the entire storage part G can be folded, so that the horizontal width when the fuselage is stored is shortened and compact, and can be easily loaded on a transportation means such as a light tiger. In addition, it can be easily accommodated even if the housing location of the aircraft is somewhat narrow.

Hereinafter, another embodiment of the ginseng harvester will be described.
As shown in FIGS. 15 and 16, an L-shaped third support plate 123 is provided in a side view in the winding region of the remaining leaf processing belt 74 and in the vicinity of the front end of the body of the remaining leaf processing roller 78. At the end of the third support plate 123 on the left and right other sides (inside the fuselage), an L shape is formed in a side view, and a front-rear width in a plan view is narrower toward the lower side in the transport direction of the remaining leaf processing conveyor 79. A rotating plate 124 is attached via a joint 125. A tension spring 126 for tensioning the rotating plate 124 upward is provided between the downward bent portion of the third support plate 123 and the downward bent portion of the rotating plate 124.

  With the above configuration, when an overload is applied in the vicinity of the front end of the remaining leaf processing roller 78 in the vicinity of the machine body, such as stones, when the overload is applied between the remaining leaf processing roller 78 and the rotation plate 124, the rotation plate 124 Is rotated downward, and a gap is formed between the remaining leaf processing roller 78 and the urine processing belt 74, so that foreign substances such as stone move from the clearance to the lower side in the conveying direction of the remaining leaf processing conveyor 79. The remaining leaf processing belt 74 can be prevented from being broken and damaged, and the durability of the remaining leaf processing conveyor 79 is improved.

  In addition, as shown in FIG. 17, the second support plate 81 is provided with an arc-shaped spring body 127 made of a leaf spring material, and the remaining leaf processing roller 78 is disposed above the spring body 127. It is good.

  With the above-described configuration, the spring body 127 can cut and cut the foliage portion remaining in the carrot with the remaining leaf processing roller 78 and the spring body 127 so that the foliage portion remaining in the carrot can be removed. This eliminates the need for an auxiliary worker to remove the remaining foliage in the post-harvest process, and eliminates the need to manually remove the foliage before cleaning or sorting. The work efficiency is improved and the labor of the worker is reduced.

  Further, when a foreign object such as a stone enters between the remaining leaf processing roller 78 and the spring body 127 and an overload is applied, the spring body 127 is crushed downward and between the remaining leaf processing roller 78 and the spring body 127. Since a gap through which stones and the like pass is generated, because foreign substances such as stone move from the gap to the lower side in the conveying direction of the remaining leaf processing conveyor 79, the remaining leaf processing belt 74 can be prevented from being broken and damaged. The durability of the remaining leaf processing conveyor 79 is improved.

  As shown in FIG. 18, when the apex of the arc portion of the spring body 127 is arranged closer to the upper side in the conveyance direction of the remaining leaf processing conveyor 79 than the lower point of the remaining leaf processing roller 78, a stone or the like is caught. At this time, since the spring body 127 is quickly crushed and a gap is formed, stones or the like are hardly rubbed against the remaining leaf processing belt 74, and the durability of the remaining leaf processing conveyor 79 is further improved.

  Further, as shown in FIG. 19, the rotating arm 128 that automatically rotates upward when rotated downward by the tension of a torque spring or the like (not shown) in the winding region of the remaining leaf processing belt 74 is rotated upward and downward. A pressure roller which is provided freely and tears off the stems and leaves remaining in the carrot by contacting the residual leaf processing roller 78 via the residual leaf processing belt 74 to the lower end of the rotating arm 128 in the conveying direction of the residual leaf processing conveyor 79. It is good also as a structure which provides 129 rotatably.

  With the above configuration, the ginseng foliage can be sandwiched between the remaining leaf processing roller 78 and the pressure roller 129 and torn off, so that the foliage remaining on the ginseng can be removed, and an auxiliary worker can follow up the harvesting process. This eliminates the need to remove the remaining foliage, and eliminates the need to manually remove the foliage before washing or sorting after harvesting. Is reduced.

  In addition, when a foreign object such as stone enters and an overload is applied, the rotation arm 128 rotates downward, and a gap through which the stone or the like passes is generated between the remaining leaf processing roller 78 and the pressing roller 129. Since contaminants such as stone move from this gap to the lower side in the conveying direction of the remaining leaf processing conveyor 79, the remaining leaf processing belt 74 can be prevented from being broken and damaged, and the durability of the remaining leaf processing conveyor 79 is improved. To do.

  When an abnormal load is applied and the rotating arm 128 does not return while rotating downward, the engine 7 is stopped or the driving force is not supplied to the remaining leaf processing conveyor 79 and the remaining leaf processing conveyor 79 is stopped. If the structure is such that the overload is applied not only to the remaining leaf processing conveyor 79 but also to the entire machine body, the durability of the machine body is improved.

  As shown in FIGS. 20 and 21, the takeover shooter 93 is rotated when the end of the takeover shooter 93 comes into contact with the conveyance lug 91 at the lower part of the left and right sides (outside the machine) of the takeover shooter 93. A rotation restricting rod 130 for determining the amount of movement is provided, and the upper portion of the rotation restricting rod 130 is brought into contact with the lower outer side of the takeover shooter 93 so that the left and right sides of the takeover shooter 93 on the left and right sides (outside the fuselage) are excessively lowered. A stopper 131 to prevent is attached. And it is good also as a structure which forms the hole part which cut the screw groove in the lower end side of this rotation control rod 130, and attaches the adjustment body 132 which cut screw grooves, such as a volt | bolt, to this hole part so that vertical position adjustment is possible.

  With the above configuration, even when carrots fall on the left and right sides of the takeover shooter 93 (outside the fuselage), the rotation restricting rod 130 contacts the rotation frame 20 to prevent it from descending too much. It is possible to prevent the carrot from being moved, and the carrot is not damaged by the impact of falling, thereby improving the product value of the carrot.

  Further, by providing the adjustment body 132 on the lower end side of the rotation restriction rod 130 so that the position of the adjustment body 132 can be adjusted in the vertical direction, the distance at which the rotation restriction rod 130 contacts the rotation frame 20 can be changed. Since it is possible to cope with various work conditions such as varieties and conditions of the field where the harvesting work is performed, work efficiency is improved.

  As shown in FIG. 22, instead of the rotation restricting rod 130, a distance sensor 133 that detects a distance is provided on one end side of the takeover shooter 93 on the left and right sides of the machine body, and the left and right other side end parts (machine body) of the takeover shooter 93. A telescopic cylinder 134 is provided at the inner end portion, and the distance from the left and right end portions of the takeover shooter 93 to the rotating frame 20 or the body frame 1 is detected by the distance sensor 133, and the detection result of the distance sensor 133 is displayed. Accordingly, the cylinder 134 may be expanded and contracted so that the inclination angle of the takeover shooter 93 can be automatically adjusted.

  According to the above configuration, since the inclination angle of the takeover shooter 93 can be changed according to the detection result of the distance sensor 133, it is not necessary for the worker or the auxiliary worker to manually correct, so that the work efficiency is improved. In addition, the labor of the operator is reduced.
