  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 disturbed.

There is no need to stand nearby, improving safety. Since the weight of the flexible container 91a used in the carrot harvester according to the present invention is about 200 kg when the carrot is fully loaded, there is a risk of being crushed if it falls down toward the worker and the auxiliary worker.

  In addition, if an adjustment operation switch 128 that is operated by hand and operates the adjustment operation motor is disposed in the vicinity of the auxiliary work seat 103 on the second selection and conveyance frame 81 on the rear side of the machine body of the selection and conveyance conveyor 88, Since the adjustment operation motor can be operated with feet, the above-described improvement in work efficiency and safety are even more remarkable.

Hereinafter, another embodiment of the ginseng harvester will be described.
As shown in FIG. 14, an L-shaped support pipe 129 is attached to the second sorting and conveying frame 81 on the rear side of the machine body, and a sheet 130 is attached to the upper end portion of the support pipe 129 so as to be able to rotate back and forth. The work seat 131 may be configured.

  According to the above configuration, when the terminal end side of the sorting and conveying conveyor 88 is moved up and down in accordance with the amount of carrot stored in the housing member 91 (flexible container 91a), the auxiliary work seat 131 moves up and down in conjunction with each other. Since the positional relationship between the sorting area on the top surface of the sorting conveyor 88 and the auxiliary worker seated on the auxiliary work seat 131 is almost the same, the carrot sorting accuracy is improved.

  In addition, by attaching the sheet 130 so as to be pivotable back and forth, the auxiliary operator can tilt the sheet 130 forward in accordance with the vertical movement on the terminal end side of the sorting and conveying conveyor 88 and perform the sorting operation in an easy-to-work posture.

  As shown in FIG. 15, among the chevron-shaped transport protrusions 84... Stuck on the surface of the sorting transport belt 83, even if the brush 132 composed of countless hairs is planted from the middle part to the upper end part in the vertical direction, Good.

  According to the above configuration, by covering the upper surface of the conveyance protrusions 84 with the brush body 132, even if the long side of the carrot faces in the left-right direction of the machine body and rests on the adjacent conveyance protrusions 84 and 84, Since the frictional force prevents the carrot from sliding down, the carrot can be prevented from slipping downward even when the conveying terminal end side of the sorting and conveying conveyor 88 is raised to be inclined upward, and the carrot is damaged by the impact of falling. This can prevent the product value of carrots.

In addition, since it is possible to prevent the carrot from reciprocating on the transport path, the work efficiency is improved.
The reason why the brush body 132 is planted only on the upper surface of the conveying protrusion 84 is to reduce the cost. However, even if the brush body 132 is implanted into the entire conveying protrusion 84, the same cost is required. If it is cheaper to plant the whole, you may plant the whole peninsula protrusion 84.

  As shown in FIGS. 16 (a) and 16 (b), the long conveying protrusions 84a having a long vertical length and the short conveying protrusions 84b having a short vertical length are alternately pasted in the left-right direction of the airframe, Also on the rear side, the long conveyance protrusions 84a and the short conveyance protrusions 84b may be alternately attached.

  According to the above configuration, even if the long side of the carrot is placed on the sorting and conveying conveyor 88 with the long side of the carrot facing in the left-right direction of the machine body, the carrot can be received by the long conveying protrusion 84a as a wall even if it slides down from the sorting and conveying conveyor 88. In addition, the carrot is prevented from being damaged by the impact of falling, and the product value of the carrot is secured, and the carrot can be prevented from reciprocating on the transport path, so that the work efficiency is improved.

If the size of the carrot is small, the short conveying protrusion 84b can also be a wall, so that the carrot can be prevented from slipping down, and the above effect can be enhanced.
Further, a portion having the long conveyance protrusion 84a on the front side of the machine body is provided with a short conveyance protrusion 84b on the rear side of the machine body, and a part having the short conveyance protrusion 84b on the front side of the machine body is provided with a long conveyance protrusion on the rear side of the machine body. By providing 84a, even if the carrot rolls on the sorting and conveying conveyor 88 in the front-rear direction, it can be stopped at the front and rear intermediate position of the sorting and conveying conveyor 88, so that the carrot is biased to the front side or the rear side of the sorting and conveying conveyor 88. It is possible to prevent ginseng from being biased into a part of the housing member 91 (flexible container 91a).

  As shown in FIGS. 17 and 18, a pair of left and right guide bars 133 and 133 are arranged below the conveyance path of the pulling and conveying device 24 to guide the ginseng ascending while guiding to the starting end side of the alignment devices 54L and 54R. A pair of left and right guide plates 131 and 131 are disposed behind the guide bars 133 and 133 and in front of the alignment devices 54L and 54R. On the inner side of the body of the guide plates 134, 134 through which the carrot foliage passes, a drooping leaf removal portion 135 for removing drooping leaves that are not pinched by the pulling and conveying device 24 is formed in a sawtooth shape. Then, the inclination angle of the guide plates 134 and 134 is configured to be gentler than the inclination angle of the guide bars 133 and 133.

  According to the above configuration, the carrots are aligned by providing the guide plates 134 and 134 with the guide bars 133 and 133 and the alignment devices 54L and 54R provided with the guide bars 134 and 134 at a smaller angle than the guide bars 133 and 133. It is possible to guide rearward while restricting upward movement from the front side in the transport direction relative to the devices 54L and 54R, preventing the carrot shoulder from coming into contact with the start end portions of the alignment devices 54L and 54R. Alignment is performed properly and work efficiency is improved.

  Further, since the saw blade-like dripping leaf removing unit 135 is formed on the guide plates 134, 134, the drooping leaves are cut before the carrots are taken over by the aligning devices 54L, 54R. It is possible to prevent drooping leaves from being entangled with the leaf-leave conveying device 65 and stop it, and work efficiency is improved.

  In addition, when the conveyance direction rear end part of the guide plates 134 and 134 is positioned on the rear side in the conveyance direction with respect to the conveyance start end part of the alignment devices 54L and 54R, the carrot foliage passes through the alignment devices 54L and 54R. The foliage portion can be guided until it is sandwiched between the defoliation transport device 65, and the foliage portion is reliably taken over.
