The left and right feedback shooters 64 and 64 that are attached to the posture and receive the carrot N from the left and right return shooters 63 and 63 and the left and right outer openings 33b and 33b and move to the hopper 4 outside the left and right return shooters 63 and 63 are conveyed. It is tilted downward toward the starting end side (front side) and is detachably attached.

If a soft member such as a flat vinyl chloride plate is laid on the upper surfaces of the left and right return shooters 63, 63 and the left and right feedback shooters 64, 64, the shock applied to the carrot N is absorbed, so that the carrot N is prevented from being damaged. Product value is improved. Further, by laying such a soft member, the carrot N can easily slide on the left and right return shooters 63 and 63 and the left and right feedback shooters 64 and 64, and on the left and right return shooters 63 and 63 and the left and right feedback shooters 64 and 64. The operation of manually returning the stopped carrot N to the hopper 4 is omitted, so that the labor of the operator can be reduced and the alignment conveying operation can be automated.
Carrots N discharged from the left and right discharge shooters 62, 62 are supplied to the left and right sorting device D behind the aligning and conveying device C, and sorted manually.

FIG. 5 shows a cross-sectional view taken along line S1-S1 in FIG.
And according to this embodiment, it is above the 2nd distribution board 31, and the conveyance direction start end part side rather than the right-and-left opening part 33a of the 2nd distribution board 31 (left-right opening part 33b of the alignment frames 29 and 29). A separation member 71 that receives the carrot N discharged from the takeover shooter 16 on the (front side) and sends it to either the left or right of the second alignment conveyance conveyors 56, 56 of the left-right alignment conveyance device C, and the side of the separation member 71 And the guide member 72 which stabilizes the attitude | position of the carrot N in conveyance above the 2nd alignment conveyance conveyors 56 and 56, and sends to the conveyance direction termination | terminus part side is provided.

The separating member 71 and the guide member 72 may be attached to the ceiling portion 29 between the alignment frames 29 and 29.
The separating member 71 and the guide member 72 are provided between the first aligning and conveying conveyors 48 and 48 and the second aligning and conveying conveyors 56 and 56, and have a plane portion in a direction perpendicular to the conveying direction of the carrot N. It is comprised from the plate-shaped member which has. When the carrot N collides with the separation member 71 while rolling on the first distribution plate 30, the carrot N moves in either the left or right direction and is distributed on the second alignment transport conveyors 56 and 56. In addition, the carrot N that travels straight in the vicinity of the ridgeline Y (FIG. 3) of the first distribution plate 30 without rolling in the left-right direction on the first distribution plate 30 collides with the separation member 71, so Can be moved in either direction.

At this time, the carrots N are fed to the second alignment belt by the guide members 72 attached to the right and left outer sides of the separation member 71 and directly above the second alignment belts 55 and 55 of the second alignment transport conveyors 56 and 56. Guided and placed on 55,55.
As shown in FIG. 5, when the cross-sectional shape of the lower end portion of the guide member 72 viewed from the conveyance direction of the carrot N is an inverted U shape or an inverted U shape, the carrot N is just an inverted U shape or an inverted U shape. Therefore, the posture of the carrot N can be stabilized one by one and sent to the end portion in the transport direction.
And if this separation member 71 and the guide member 72 are comprised with a soft member (rubber board, a vinyl chloride board, etc.), it will prevent that the carrot N is damaged by the impact of a collision.

  By adopting this configuration, above the second distribution plate 31 and closer to the transport direction start end side than the left and right openings 33a of the second distribution plate 31 (the left and right openings 33b of the alignment frames 29 and 29). By providing the separating member 71 to be sent to either the left or right side of the left-right aligned transport device C, the carrot N can be reliably moved to the left-right aligned transport device C. That is, it is possible to reduce the carrot N that slides on the second distribution plate 31 and falls to the left and right opening 33a (left and right opening 33b) and the carrot N that jumps out of the body from the end of the second distribution plate 31. The carrot N that moves from the left and right return shooters 63, 63 to the hopper 4 of the storage section A and returns to the transport path is reduced, so that the work efficiency is improved, and the carrot N that is damaged by the impact of dropping to the outside of the machine body is reduced. The commercial value of carrot N is improved.

  Further, a guide member 72 that stabilizes the posture of the carrot N being conveyed on the side of the separation member 71 and above the second alignment conveyance conveyors 56, 56 of the left and right alignment conveyance device C and sends it to the end portion in the conveyance direction. By providing, the carrot N on the left-right aligned transport device C can be adjusted to a stable posture, so that the carrot N being transported is caused by the vibration of the left-right aligned transport device C or the collision of the carrots N with each other. 31 is prevented from falling inside the second alignment conveyors 56, 56 (between the second alignment belts 55, 55), and the work efficiency is improved.

  Moreover, between the 2nd distribution board 31 and the separation member 71, it is the up-down direction to the left-right outer part from the center part with respect to the conveyance direction of the carrot N of the 2nd alignment conveyance conveyors 56 and 56 of the left-right alignment conveyance apparatus C. A space portion K is provided so that the interval W is wide. And as shown in FIG. 5, the distance W1 between the top part (ridgeline part Y) of the center of the 2nd distribution board 31, and the separation member 71, the right and left both ends of the 2nd distribution board 31, and the separation member 71, The distance W2 between is such that W1 <W2.

  By operating this configuration, the formation of the space K prevents the carrot N that collides against the separating member 71 from stopping on the spot, so that the second alignment of the left and right aligning / conveying device C is manually performed. The work of returning to the conveyors 56, 56 is omitted, and the work efficiency is improved.

  In addition, the vertical alignment W of the space K is increased from the center to the left and right outer sides with respect to the crop transfer direction of the second alignment transfer conveyors 56 and 56 of the left and right alignment transfer device C. Since it is prevented that crops that have fallen and moved toward the vicinity of the conveyors 56 and 56 are clogged in the space K and do not move, the work of manually returning the crops to the second aligned conveyors 56 and 56 is omitted. Work efficiency is improved.

In particular, crops having a tapered portion such as carrot N and Japanese radish may be clogged between the second distribution plate 31 and the separating member 71. The separation member 71 and the guide member 72 may be configured to be movable in the front-rear direction with respect to the carrot N conveyance direction.
In the illustrated example, it is provided just between the first aligning and conveying conveyors 48 and 48 and the second aligning and conveying conveyors 56 and 56, for example, above the first sorting plate 30 on the first aligning and conveying conveyors 48 and 48. Even if it provides, you may provide above the 2nd distribution board 31 on the 2nd alignment conveyance conveyor 56,56.

  And this separation member 71 is provided with a plurality of slits 71a in the left-right direction with respect to the crop conveying direction of the second aligned conveying conveyors 56, 56 of the left-right aligned conveying device C, and the length of the slits 71a in the vertical direction is It is good also as a structure which lengthens from the center part to the left-right outer part, and becomes so that the space | interval of adjacent slit 71a becomes narrow from the center part to the left-right outer part.

As shown in FIG. 4, the length L1 in the vertical direction of the slit 71a in the center in the left-right direction with respect to the crop transport direction of the second aligning transport conveyors 56, 56 of the left-right aligned transport device C is the slit 71a in the left-right outer part. The length L is made shorter than the vertical length L2 (L1 <L2), and the length L is gradually increased from the center portion to the left and right outer portions.
Further, the interval M between the adjacent slits 71a is set such that the interval M1 between the slits 71a in the central portion is wider than the interval M2 between the slits 71a in the left and right outer portions (M1> M2).

  By adopting this configuration, the slit 71a is formed in the separation member 71, so that even if the carrot N is clogged in the space K between the separation member 71 and the second distribution plate 31, the separation member 71 is Since the carrot N is moved slightly, the work of returning to the second aligning and conveying conveyors 56 and 56 of the left and right aligning and conveying apparatus C is omitted, and the working efficiency is improved. In addition, carrots N of different varieties and sizes can be stably supported. For example, even in the case of a relatively small size carrot N, the carrots N are not abruptly rolled on the second alignment transport conveyors 56, 56 and are damaged. Can be gradually dropped, and even in the case of a large carrot N, it is prevented from being caught by the separation member 71 and stopping.

  The length of the slit 71a is increased by increasing the length L in the vertical direction of the slit 71a from the central portion toward the left and right outer portions and by decreasing the interval M between the adjacent slits 71a from the central portion toward the left and right outer portions. The slit 71a hardly moves in the part where the slits 71a are short and the gap between the slits 71a is wide (near the central part of the left and right aligning and conveying apparatus C), and the separating member 71 repels the colliding carrot N and Since it can be moved to the two-arrangement conveyers 56, 56, the carrot N that moves from the left and right return shooters 63, 63 to the hopper 4 of the storage section A and returns to the conveyance path is reduced, so that the work efficiency is improved.

  On the other hand, in the portion where the length of the slit 71a is long and the interval between the slits 71a is narrow (near the left and right outer sides of the left and right aligning and conveying device (C)), the slit 71a reduces the speed of the carrot N and the second aligning and conveying conveyor 56, 56, the carrot N can be placed in a stable posture on the second aligning and conveying conveyors 56 and 56, so that the carrot N being conveyed is moved by the vibration of the left and right aligning and conveying apparatus C or the collision between the carrots N. It is prevented from dropping from the second distribution plate 31 to the inside of the second alignment transport conveyors 56, 56 (between the second alignment belts 55, 55), and the work efficiency is improved.

The vertical length L of the slit 71a is preferably about 20 mm on the innermost side (near the ridge line portion Y) and about 50 to 60 mm on the outer end. The balance between the inner side and the outer end portion is good when the length is increased by about +5 to 10 mm toward the outside.
Further, if the guide member 72 is also provided with a plurality of slits 72a, the carrot N of different varieties and sizes can be stably supported, so that the posture of the carrot N can be stabilized and sent to the end portion in the conveyance direction. .
Further, when the separation member 71 and the guide member 72 are integrally formed, the member can be easily attached and detached. Further, when the front and rear positions of the separation member 71 and the guide member 72 are configured to be adjustable, the front and rear positions can be easily adjusted.

Furthermore, the left and right second alignments of the carrots N aligned one by one on the second alignment and transport conveyors 56 and 56 of the left and right aligned transport device C are disposed on the inner side (second distribution plate 31 side) upper portion of the regulating member 70. Drop prevention guides 73 and 73 are provided on the left and right sides to prevent the belts 55 and 55 from falling inward. The fall prevention guide 73 has a cylindrical shape having a longitudinal direction in the conveying direction of the carrot N (may be a square pillar shape or the like), and the front end portion of the left and right opening 33a (left and right opening 33b) of the second distribution plate 31. From the rear end to the end in the conveying direction (rear). In addition, if the shape of the fall prevention guide 73 is a cylindrical shape, even if the carrot N touches the side surface of the fall prevention guide 73, it is prevented from being damaged.
In this way, by providing the fall prevention guide 73, the carrot N being transported is moved from the second sorting plate 31 to the second aligned transport device C by the vibration of the left-right aligned transport device C or the collision of the carrots N. It is prevented from falling inside the conveyors 56, 56 (between the second alignment belts 55, 55), and the work efficiency is improved.

  Further, when the fall prevention guide 73 is provided from the front end of the left and right opening 33a (left and right opening 33b) of the second distribution plate 31 from the rear end to the end of the conveying direction, the carrot N is opened to the left and right openings. Since falling can be prevented until it passes the side of 33a (right-and-left opening part 33b), the carrot N in conveyance is separated from the 2nd distribution board 31 by the vibration of the left-right alignment conveyance apparatus C, or the collision of the carrots N. It is prevented from falling to the inside (between the second alignment belts 55, 55) of the second alignment transport conveyors 56, 56 of the left-right alignment transport device C, and the work efficiency is improved.

When the carrots N that are not aligned on the second alignment transport conveyors 56 and 56 and a plurality of carrots N are simultaneously riding, the carrots N other than the carrots N that are on the second alignment belts 55 and 55 are dropped. It falls from the left and right openings 33a and 33b without receiving the action of the prevention guide 73.
Further, if the conveyance start end side (front side) of the fall prevention guide 73 is bent downward, the carrot N is prevented from being damaged even if it contacts the conveyance start end side of the fall prevention guide 73. Product value is improved.

  Further, when the fall prevention guide 73 is attached to the regulation member 70 via the support member 75 between the fall prevention guide 73 and the regulation member 70 of the second alignment belt 55, the support member 75 is formed of an elastic body (rubber or the like). Even when the diameter of the carrot N is large, the fall prevention guide 73 can be retracted between the second alignment belt 55 and the fall prevention guide 73 in accordance with the diameter of the carrot N. The fall from the inside (between the second alignment belts 55, 55) of the second alignment conveyors 56, 56 of the alignment conveyor C is prevented.

6 shows a plan view of the crop conveyance device when the left and right feedback shooters 64, 64 of the crop conveyance device shown in FIGS. 1 and 3 are changed, and FIG. 7 shows a side view of the crop conveyance device of FIG. The figure is shown. FIG. 8 shows a rear view of the left feedback shooter 64.
6 and 7 show the state of the carrot N moving on the left and right feedback shooters 64 and 64.

  As described above, the carrot N falling from the left and right return shooters 63 and 63 and the left and right outer openings 33b and 33b (FIG. 2) moves from the left and right feedback shooters 64 and 64 to the hopper 4. If the number of the carrots N moving on the left and right feedback shooters 64, 64 increases, the distance between the carrots N may be clogged and stopped, or may be damaged.

In order to prevent such a problem, if the left and right widths of the left and right feedback shooters 64 and 64 are widened, the size of the crop conveying device itself is increased and the compactness is lost.
However, as shown in FIG. 6, only the left and right feedback shooters 64, 64 in the vicinity of the left and right return shooters 63, 63 may be bulged outward (for example, about +25 mm to about 100 mm).

  In the vicinity of the left and right return shooters 63, 63 of the left and right feedback shooters 64, 64, especially the carrots N falling from the left and right return shooters 63, 63 and the left and right outer openings 33b, 33b tend to concentrate. May stop.

Therefore, if the width of the left and right feedback shooters 64, 64 only at the entrance (upper part) is widened (indicated by "d" in the figure) and the other parts are the same size (left and right width) as before, the crop conveying device The carrots N on the left and right feedback shooters 64 and 64 can be smoothly sent to the hopper 4.
The length of the left and right feedback shooters 64 and 64 having the bulge d in the front-rear direction is preferably equal to or longer than one carrot (for example, about 250 mm or more). By giving the carrot N more than the length of one carrot, the direction of the carrot N turned sideways can be changed in the direction of the arrow P, so that the carrot N stays at the left and right feedback shooters 64 and 64 entrances. Can be prevented.

Further, as shown in FIGS. 7 and 8, when a gentle slope H is applied from the bulge d portion (wide portion) of the left and right feedback shooters 64, 64 to the hopper 4, the carrot N easily flows into the hopper 4 smoothly. Become.
Furthermore, it is preferable to incline the outer bottom portion of the bulge d portion of the left and right feedback shooters 64, 64 toward the inside of the angle θ (for example, about 13 to 20 degrees in FIG. 6).

  By adopting this configuration, the tip of the carrot N that has entered the feedback shooters 64 and 64 rides on the tip of the inclined portion with the momentum of inflow (falling), so that the carrot N is from sideways (position A in FIG. 6). It becomes easy to change the direction of the arrow P to the vertical direction (position B). When the carrot N is oriented vertically, it easily flows along the inclination of the left and right feedback shooters 64 and 64, so that the carrot N can be prevented from staying on the left and right feedback shooters 64 and 64.

  FIG. 9 is a plan view of a crop conveying apparatus showing another example of the feedback shooters 64 and 64 of FIGS. 6 and 7, and FIG. 10 is a side view of the crop conveying apparatus of FIG. 9 and 10 also show the state of the carrot N moving on the left and right feedback shooters 64 and 64.

On the other hand, without providing the bulge d portion of the left and right feedback shooters 64 and 64 as shown in FIGS. 6 and 7, the left and right width of the crop conveying device (the left and right width of the feedback shooters 64 and 64) is maintained in a more compact manner. It is preferable if the carrot N can be prevented from staying on the feedback shooters 64 and 64.
Therefore, when the slope portion r (FIG. 9) is provided on the outer upper portion of the inlet portion of the feedback shooters 64, 64 from the outside to the inside, the carrot N that has entered the feedback shooters 64, 64 hits the slope portion r, and the arrow P It becomes easy to turn inward in the direction (FIG. 6). Accordingly, since the carrot N easily flows along the inclination of the left and right feedback shooters 64 and 64, the carrot N can be prevented from staying on the left and right feedback shooters 64 and 64.

Also, in the side view (FIG. 10), by providing the slope portion r, the carrot N is more likely to flow along the slope from the slope portion r of the left and right feedback shooters 64, 64. It is possible to prevent the carrot N from staying in the tank.
Further, it is convenient if the slope portion r above the feedback shooters 64, 64 is hooked by a hook 80 (FIG. 9) and can be removed according to the state of crop conveyance. For example, when the number of carrots N is large, the slope portion r can be hooked on the feedback shooters 64 and 64 using hooks 80 and used, and when the number of carrots N is small, the slope portion r can be removed. That's fine.

By adopting this configuration, it is possible to use the feedback shooters 64 and 64 according to the state of crop conveyance, which is convenient and has good work efficiency.
When a slippery glossy waterproof material is used for the surface of the slope portion r, the tip of the carrot N is easily turned inward in the direction of arrow P (FIG. 6). Accordingly, since the carrot N easily flows along the inclination of the left and right feedback shooters 64 and 64, it is preferable because the carrot N can be prevented from staying on the left and right feedback shooters 64 and 64.

FIG. 11 is a plan view of a crop conveying apparatus showing another example of the feedback shooters 64 and 64 of FIGS. 6 and 7, and FIG. 12 is a side view of the crop conveying apparatus of FIG. 11 and 12 also show the state of the carrot N moving on the left and right feedback shooters 64 and 64, as in FIGS. 6, 7, 9, and 10.
Further, a free roller 83 may be arranged at the inlet portion (upper part) of the feedback shooters 64, 64 so that the tip of the carrot N is directed downward (to the hopper 4 side). Although three free rollers 83 are provided in the illustrated example, the number is not limited, and the same applies to FIG.

  When the carrots N falling from the left and right return shooters 63 and 63 and the left and right outer openings 33b and 33b enter the left and right feedback shooters 64 and 64, the free rollers 83 at the entrance portion move the A position to the B position and then the C position. The left and right feedback shooters 64 and 64 can be smoothly moved and sent to the hopper 4.

A plurality of free rollers 83 are preferably provided on the left and right outer sides of the feedback shooters 64 and 64 (on the left and right return shooters 63 and 63 side). By providing a plurality of free rollers 83 on the left and right outer sides of the feedback shooters 64, 64, the carrot N that has moved to the left and right outer sides of the feedback shooters 64, 64 with the momentum to flow (fall) into the feedback shooters 64, 64 can be Since it is guided to the inside by sliding, it becomes easy to change direction.
Accordingly, since the carrot N easily flows along the inclination of the left and right feedback shooters 64 and 64, the carrot N can be prevented from staying on the left and right feedback shooters 64 and 64.

  Further, as shown in the round frame portion of FIG. 11, when the free roller 83 has a tapered shape in which the outer diameter φA is made larger than the inner diameter φB, the carrot that flows into (falls) vigorously into the feedback shooters 64 and 64. As N moves to the left and right outer sides of the feedback shooters 64, 64, it becomes easier to roll inward, and the direction of carrot N to the inside becomes easier.

  In FIG. 13, the top view of the crop conveyance apparatus which showed another example of the feedback shooters 64 and 64 of FIG.6 and FIG.7 is shown. The side view of the crop conveyance device in FIG. 13 is the same as that in FIG. In the example shown in FIG. 11, a plurality of free rollers 83 are provided on the left and right outer sides of the feedback shooters 64, 64. However, as shown in FIG. It may be arranged over the shooter 63, 63 side).

If the tip of the carrot N hits the outer wall of the feedback shooters 64 and 64 with the momentum of flowing (falling) into the feedback shooters 64 and 64, the carrot N may remain as it is and become a stick that prevents the other carrots N from flowing in.
However, by providing the free roller 83 from the center to the inside of the feedback shooters 64, 64, the direction of the carrot N before the carrot N becomes a stick in this way, that is, before it hits the outer wall of the feedback shooters 64, 64. Can be changed. Then, the free roller 83 at the entrance can smoothly move from the A position to the B position and then to the C position on the left and right feedback shooters 64 and 64 and send it to the hopper 4. The carrot N flows in the direction of arrow P along the inclination of the left and right feedback shooters 64, 64, and the carrot N can be prevented from staying on the left and right feedback shooters 64, 64.

  FIG. 14 is a plan view of a crop conveyance device showing another example of the feedback shooters 64 and 64 of FIGS. 6 and 7. The side view of the crop conveyance device in FIG. 14 is the same as that in FIG.

  Further, the left and right widths (axial lengths) of the free rollers 83 at the inlet portions (upper portions) of the feedback shooters 64 and 64 are the same as the left and right widths of the bottom surfaces of the feedback shooters 64 and 64, You may arrange | position over. By disposing the free roller 83 over the entire lateral width of the feedback shooters 64, 64, the free roller 83 acts regardless of where the carrot N moves.

Therefore, the carrot N flows along the inclination of the left and right feedback shooters 64 and 64 by the action of the free roller 83, and the carrot N can be prevented from staying on the left and right feedback shooters 64 and 64.
In the illustrated example, the left and right width of one free roller 83 is the same as the left and right widths of the feedback shooters 64 and 64. However, a plurality of free rollers 83 are provided in the left and right direction of the feedback shooters 64 and 64. You may arrange | position so that the horizontal width of the whole which match | combined the roller 83 may match the horizontal width of the feedback shooters 64 and 64.

FIG. 15 is a plan view of a crop conveyance device showing another example of the feedback shooters 64 and 64 of FIGS. 6 and 7, and FIG. 16 is a side view of the crop conveyance device of FIG.
Further, a free roller 84 may be further provided on the outer wall (left and right side walls) of the inlet portion (upper part) of the feedback shooter 64, 64 outside the free roller 83 provided on the bottom surface of the feedback shooter 64, 64 in FIG. . Even if the carrot N flows into the feedback shooters 64 and 64 and the tip of the carrot N hits the outer wall of the feedback shooters 64 and 64 and becomes a replacement rod that prevents the flow of other carrots N, the free rollers 84 provided on the outer wall Such a direction of the carrot N can be changed, and the carrot N can be smoothly moved on the left and right feedback shooters 64 and 64 and sent to the hopper 4.

As shown in FIG. 16, the free roller 84 is placed outside the free roller 83 and the feedback shooter so that the axial direction (longitudinal direction) of the free roller 84 is substantially perpendicular to the bottom surfaces of the left and right feedback shooters 64 and 64. 64 and 64 are arranged so as to lean against the left and right outer sides of the bottom surface.
In this way, by placing the free roller 84 so as to lean on the outer wall on the outer side of the free roller 83, even if the carrots N moved to the left and right outer walls of the feedback shooters 64 and 64 overlap with each other, the free roller 84 is surely provided. Therefore, even if the carrots N overlap and flow into the feedback shooters 64, 64, the carrot N is clogged and stays on the feedback shooters 64, 64. This can be further prevented.

The free rollers 83 attached to the left and right outer walls of the feedback shooters 64 and 64 are so that the upper roller diameter φD is smaller than the lower roller diameter φC as shown in a round frame in a side view (FIG. 16). Good. By setting φD <φC, when the tip of the carrot N moves to the lower side of the free roller 83, the carrot N is guided to the hopper 4 side by the rotation of the free roller 83.
If the upper roller diameter φD is larger than the lower roller diameter φC (φD> φC), the carrot N is sandwiched between the lower side of the free roller 83 and the bottom surface of the feedback shooter 64, and the carrot N is clogged. May end up.
However, by adopting this configuration, it is possible to prevent the carrot N from clogging and staying on the feedback shooters 64 and 64 even if the tip of the carrot N moves to the lower side of the free roller 83.

Further, a drive mechanism (not shown) of the free rollers 83 and 84 is driven so that the free rollers 83 and 84 provided at the inlet portions (upper portions) of the feedback shooters 64 and 64 are driven to forcibly guide the carrot N to the hopper 4. ) May be provided.
By driving the free rollers 83 and 84, the carrot N is forcibly conveyed on the left and right feedback shooters 64 and 64 and flows downward along the inclination, so that the carrot N stays on the left and right feedback shooters 64 and 64. Can be surely prevented.

FIG. 17 is a plan view of a crop conveyance device showing another example of the feedback shooters 64 and 64 of FIGS. 6 and 7, and FIG. 18 is a side view of the crop conveyance device of FIG.
Furthermore, the free rollers 83 and 84 provided at the inlet portions (upper portions) of the feedback shooters 64 and 64 shown in FIGS. As shown in FIGS. 17 and 18, pulleys 87 and 87 and pulleys 88 and 88 are provided at two positions on the bottom of the entrance and left and right outer walls of the left and right feedback shooters 64 and 64, respectively. By changing the conveyor belts 89 and 90 between 88 and 88, it can be changed easily.

  In the configuration of the above-described free rollers 83 and 84, the carrot N may be clogged between the free rollers 83 and 83 and between the free rollers 84 and 84. Since it can be sent below the left and right feedback shooters 64, 64, it is possible to more reliably prevent the carrot N from staying on the left and right feedback shooters 64, 64.
