BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor device for selecting crops, which is configured to sequentially carry and convey crops to be conveyed such as carrots, radish and other root vegetables, and send them to the next process in a predetermined posture. For the selection of crops provided with a carry-out section for carrying out and carrying out the carried crops from the storage section, and a sequential feeding and carrying apparatus for sequentially sending the carried crops sent from the carry-out section one by one to the next step. Concerning a carrier device.

2. Description of the Related Art In the above-mentioned crop sorting and conveying apparatus, conventionally, in the above crop sorting and conveying apparatus, conventionally, for example, locking projections are formed at a predetermined pitch on the outer peripheral surface of an endless rotating belt to cover the crops. A structure in which the transported crops are sequentially placed and locked by the respective locking projections and placed and transported one by one,
Alternatively, it is conceivable that a pair of left and right endless rotation zones is supported by rollers that are freely rotatable at a predetermined pitch, and one crop is placed between each roller and conveyed.

[0003]

In the conventional structure as described above, the crops are sequentially placed and conveyed one by one, and the weight and length of the crops are measured, and the automatic sorting and sorting based on the measurement results are performed. It was sent to the work process to enable automatic selection of this type of crop.

However, in the above-mentioned conventional structure, it is not always the case that the crops are surely placed and guided one by one in the predetermined posture between the above-mentioned locking projections and the respective rollers. There is a high possibility that troubles such as a case where two or more pieces are placed on the protrusion or a case where the crop is not placed are generated,
Further, in the latter conventional structure, there is a great possibility that the crop is placed over a plurality of rollers and the like.
It has been impossible to reliably place and convey one by one with a predetermined pitch. In addition, there is a risk that crops will accumulate during transport and become clogged, resulting in damage.
There was room for improvement.

The present invention solves the above-mentioned problems and enables the crops to be transported reliably and efficiently one by one, while the damage to the crops can be suppressed as much as possible. The present invention is to provide a transportation device for sorting.

[0006]

A feature of the present invention is that in the crop sorting and conveying apparatus described at the beginning, an upper crop placing surface having a width substantially the same as the width of the conveyed crop is provided.
A drive mechanism for arranging a plurality of carriers configured in an inclined position, which are located downward toward the lower side in the transport direction of the transported crop, in parallel along the transport direction of the transported crop, and vertically moving each of the transport bodies at a predetermined pitch. With the provision of the above, the drive timing is set such that adjacent transport bodies move up and down in a contradictory manner, and the sequential feed placement transport device is configured, and from the terminal end of the unloading section to the start end of the sequential transport placement transport device. Is configured to guide the conveyed crop downward through a guide chute toward the section, and from the upper side of the guide chute toward the conveying body on the starting end side of the progressive-placing and conveying device in a sheet shape. The point is that the elastic body is extended.

[0007]

In the progressive feeding device, each of the above-mentioned carriers moves up and down, and the crops move while the mounted crops are sequentially transferred to the lower carrier by the tilted posture of the crop-mounting surface. go. Since the width of the carrier is almost the same as the width of the crop, the crops that are vertically stacked are collapsed and leveled by repeating the feeding operation as described above. Only individual crops are placed. As a result, even when a plurality of crops to be conveyed are superposed and sent in from the superior side of conveyance, one piece is always sent to the next step at the end of the conveyance. In addition, since the conveyed crops are guided down from the carry-out section through the guide chute, even when a plurality of conveyed crops are overlapped and sent out from the carry-out section, the overlap is destroyed by the flow-down guide and the conveyed body is conveyed. Separation and transportation by means of becomes smooth. Further, since the sheet-shaped elastic body is extended, it is possible to prevent the crop guided down from directly colliding with and damaging the carrier at the starting end portion which moves up and down, and the cushioning action due to the deformation of the sheet-shaped elastic body. This softens the hit and prevents damage.

[0008]

[Effects of the Invention] Therefore, although the crops can be reliably sent to the subsequent process one by one by the rational structure improvement, the automatic selection work of this kind of crops can be performed in a state where there is little crop damage. It became possible, and there was little risk of damaging the crop even if the transportation speed was increased, and the work efficiency could be improved.
