Pulleys 109 and 109 are fixed, and driven pulleys 111 and 111 are provided at the front ends of the holding frames 106 and 106 (ends of the shaping rollers 33 and 33), and further between the driving pulleys 109 and 109 and the driven pulleys 111 and 111 Further, sandwiching and conveying belts 112 and 112 for sandwiching the spherical portion of the onion are provided so as to be opposed to the left and right.
Further, a plurality of idler pulleys 113 and 113 for imparting an appropriate clamping force to the clamping and conveying belts 112 and 112 are provided to form a clamping and conveying path between the facing portions of the clamping and conveying belts 112 and 112.
As another embodiment, the driving force of the alignment feed rollers 34, 34 can be transmitted from a transmission mechanism (belt, gear, etc.) as a power transmission mechanism to the sandwiching conveyor belts 112, 112.

  On the outer periphery of the left and right holding and conveying belts 112, a holding surface having a substantially cross-sectional shape formed of an elastic material such as rubber or foaming synthetic resin is formed, and the left and right holding surfaces are aligned feeding rollers. 34 and 34 and the shape forming rollers 33 and 33 are configured to hold the spherical portion of the onion that is fed later and convey it backward.

Next, an example in the case of using the above-described crop sequential delivery device 100 for onion and the operation of each part will be described.
The onion vegetated in the field is harvested by a harvesting machine. The harvesting machine extracts the onion from the ground, cuts the stem part from the side of the ball to about 10 cm to 20 cm, and then releases it to the ground. The onion thus released is sun-dried and then collected in the container CT. In this example, the onion collected in the container CT is used.

  Then, the support leg bar member 29 is erected to hold the container receiving body portion 28 in a horizontal state, and the container CT in which a large number of onions are accommodated is placed on the bottom frame portion 28a of the container receiving body portion 28. Then, hold the tip of one of the left and right operation rod members 30 and rotate it to the rear side of the left and right fulcrum shaft 31 so that the container receiver main body 28 exceeds the vertical posture around the left and right axis 26 as shown in FIG. As a result, the container CT is turned over together with the container receiving body 28.

  A large number of onions in the container CT reversed in this way are put into the crop receiving part WS surrounded by the left and right side wall parts 4a and 4b, the load receiving stand 5 and the transporting part 6 all at once. And flows toward the bucket 19 of the transport unit 6, and when some onions reach the transport unit 6, each of the onions comes into contact with the transport body 16 and moves upward as the transport body 16 moves. As shown in FIG. 10, the buckets 19 are lifted up one after another from the lower vicinity of the front end of the load receiving platform 5 and are then transported upward. Since the onion at the foremost position on the load receiving table 5 does not exist sequentially by the conveyance, a large number of onions on the load receiving table 5 are sequentially fed forward in the conveying direction.

At this time, the forward movement of the onion on the load receiving table 5 is caused by the inclination angle B2 of the inclined walls 5b and 5c of the load receiving table 5 and the gravity of the onion by the tapered angle B1, and the rear shaft 10 of the load receiving table 5. It is promoted by the vertical swinging around and the stirring action by the movement of the bucket 19.
Further, the tapered bowls formed by the inclined walls 5b and 5c provided on the upper surface of the bottom plate 5a and the inclination angle B2 of the inclined walls 5b and 5c are guided and guided one by one to the movement path of the bucket 19. The onion can be scooped up by the bucket 19.
Further, by integrally configuring the load receiving tray 5 with a plate material, it contributes to preventing damage when sliding on the onion.
Each bucket 19 may try to scoop up two or more onions, but by restricting the width of the bucket 19 and arranging the buckets 19 in a staggered manner in the left-right direction after the installation plate 37, always It is possible to leave only one onion on the top and drop off the rest.

  Each onion lifted up in each of the left and right buckets 19 reaches the end of conveyance from the top of the sprocket 14a of the upper left and right shaft 14, and is turned toward the chute 35 at this time. When a centrifugal force acts on each onion and each bucket 19 changes to a substantially inverted posture, the onion placed on each bucket 19 flies forward in the conveying direction as shown in FIGS. The blown onion collides with the soft plate member 35e of the chute 35, is received by the soft plate member 35a as a buffer, slides forward in the conveying direction, and falls from the lower end of the chute 35.

As shown in FIG. 11, the onion thus dropped sequentially falls between the pair of left and right shaping rollers 33 and 33 and on the feeding start end portions of the pair of left and right alignment feeding rollers 34 and 34. 33 and the alignment feed rollers 34 and 34 are in a horizontal position, and are moved forward in the transport direction by a pair of left and right alignment feed rollers 34 and 34. The stem portion is sandwiched between the rollers 34 and 34 and pulled down. Therefore, each onion moves forward in the conveying direction in an aligned state at a distance of about 10 cm, for example, by a pair of left and right aligned feed rollers 34 and 34.
The onion preparation machine B receives each onion thus delivered from the conveying end, separates its root and stem, forms a ball as a product, and sequentially discharges it to a specific place.

  The above-mentioned crop sequential supply device according to the present invention is not limited to onion, but can be used for supplying the crop W having a ball portion and a stem portion, and can be appropriately changed within the scope of the present invention. It does not matter.
