falls forward along the inclined surface of the distribution body 34 and is stored in the front part of the bunker 3.

Then, the potatoes a falling down one after another in the front part of the bunker 3 are stored in a mountain-like shape gradually higher, and as this collapses, the base widens and is stored on the bottom plate part 4 on the front side of the bunker 3.

In addition, when storing potatoes a in the rear part of the bunker 3, the handle 31 is removed from the locking recess 33 in the front part of the locking body 32, and instead, the handle 31 is placed in the middle part of the locking body 32. When engaged in the locking recess 33, the sorting body 34 supported by the operating rod 29 and the supporting rod 36 is located below the unloading section 9 of the sorting conveyor 8 and moves backward, as shown by the dotted line in FIG. Therefore, the potatoes a dropped from the unloading section 9 fall backward along the inclined surface on the back side of the sorting body 34 and are stored in the rear part of the bunker 3. Then, the potatoes a which fall one after another in the rear part of the bunker 3 are stored in a mountain-like shape and are gradually stored higher, and are stored on the bottom plate part 4 on the rear side of the bunker 3 while the base is widening as this collapses. In this way, the distribution body 34
By appropriately changing the position of the bunker 3 and slanting it towards the front and rear parts of the bunker 3, it is possible to smoothly and evenly store the potatoes a without being lopsided on the bottom plate part 4 of the bunker 3. At the same time, it is possible to gradually stack them higher and store them.

In the above case, the cushioning material 34a is attached to the front and back surfaces of the sorting body 34 that receives the potatoes a, so that the potatoes a dropped from the delivery section 9 onto the sorting body 34 are cushioned and damaged. There is no such thing.

In addition, when the potatoes a are stacked at a predetermined height in the bunker 3, that is, so that the distance between the carrying-out section 9 and the stored potatoes a becomes small, and there is no longer a need for the distribution body 34 to intervene, Remove the handle 31 from the locking recess 33 in the middle of the locking body 32,

Note that the distribution body 34 may be formed of an elastic member such as rubber or synthetic resin.

(6) Effects of the invention According to the invention, when the handle is rotated depending on the storage status of agricultural products in the bunker, the operating rod is moved up and down, and the position of the operating rod is used to move the handle through the support rod. The set position of the sorting body is reliably maintained by automatically changing the position of the sorting body in the direction of sorting the agricultural products, and by locking the handle in a locking recess at a predetermined position of the locking body. The agricultural products carried out from the unloading section of the transporting body can be effectively utilized to evenly distribute and store the agricultural products carried out from the unloading section of the transporting body using this sorting body. This prevents agricultural products from being piled up and stored on one side of the bunker, and since the front and back surfaces of this sorting body that receive agricultural products have cushioning material, the cushioning action prevents the transportation of the conveyor. Agricultural products carried out from the bunker can be stored in the bunker without being damaged. Therefore, by operating the handle, the position of the sorting body is automatically changed through the operating rod and the support rod, and the sorting body is then distributed. A simple and easy-to-operate structure with configurable orientation allows for easy distribution and storage of agricultural products in large volume bunkers without damaging or skewing them.
