Next, an example 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 cargo receiving stage 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 cargo receiving platform 5 and are then conveyed upward. Since the onion at the foremost position on the load receiving platform 5 does not exist sequentially by the conveyance, a large number of onions on the load receiving platform 5 are sequentially fed forward in the conveying direction.

At this time, the forward feeding operation of the onion on the load receiving platform 5 is performed by the inclination angle B2 of the inclined walls 5b and 5c provided on the load receiving platform 5, the taper angle B1, the vertical swing of the load receiving platform 5, It is promoted by the gravity of the onion or the stirring action by the movement of the bucket 19.
Furthermore, the onion is guided and guided one by one into the movement locus of the bucket 19 by the tapered bowl shape formed by the inclined walls 5b and 5c provided on the upper surface of the bottom plate portion 5a and the inclination angle B2 of the inclined walls 5b and 5c. The onion can be scooped up with the bucket 19.
In addition, 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 arranging the buckets 19 in a zigzag pattern, only one onion is always left on the top, and the others Can be dropped.

  Each onion W picked up in each of the left and right buckets 19 reaches the sprocket 14a portion of the upper left and right rotating shaft 14, and is turned forward in the conveying direction around the left and right rotating shaft 14, At this time, when a centrifugal force acts on the onion W and each bucket 19 changes to a substantially inverted posture, as shown in FIG. 8, the onion W placed on each bucket 19 is blown forward. The onion W thus blown down falls into the chute 35 and is received by the soft plate member 35a in a shock-absorbing manner. The feed start ends of the pair of left and right shaping rollers 33 and 33 and the pair of left and right alignment feed rollers 34 and 34 To be guided to.

As shown in FIG. 12, 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, and the stem portion is sandwiched and pulled down by the opposed portions of the rollers 34 and 34. 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.
