2. Description of the Related Art Conventionally, in the above-described crop sorting / conveying apparatus, locking projections are formed at a predetermined pitch, for example, on the outer peripheral surface of an endless rotating belt, and the crops to be transported are sequentially placed by the respective locking projections. Stopping and transporting one by one, or a pair of left and right endless rotating belts, supporting a free-rotating roller at a predetermined pitch, and cropping one by one between each roller. A device configured to be placed and transported was considered.

[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 after the automatic sorting and sorting based on the measurement results. 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 possibility that crops may accumulate and become clogged during transportation, and there is room for improvement.

An object of the present invention is to solve the above-mentioned problems and to provide a crop sorting and conveying device which can surely convey crops one by one.

[0006]

According to a characteristic configuration of the present invention, 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. Is provided, the drive timing is set so that adjacent transport bodies move up and down in a contradictory manner, and the sequential feeding and placement transport device is configured, and the transport width of each transport body is narrowed toward the transport terminal end side. In addition to the above configuration, each transport body is inclined along the transport width direction, and the horizontal inclination angle with respect to the transport body is sequentially changed so that the transport end portion side is set to be gentle.

[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, the vertical drive of each carrier only needs to consider the timing of movement of adjacent ones, and a simple drive structure is sufficient. In addition, since the conveyance width of each conveyance body is wide at the starting end and the inclination angle is large, even when the conveyed crops are overlapped and fed in, they are laterally displaced as the conveyance body is driven. They are leveled and placed one by one. Then, as it is conveyed, the inclination angle gradually becomes smaller and the conveyance width becomes narrower.
Only one crop to be transported is placed on each carrier, and at the terminal end, one crop is delivered.

[0008]

Therefore, the rational structure improvement makes it possible to reliably send the conveyed crops one by one to the subsequent step, and it becomes possible to efficiently perform the automatic selection work of this kind of crops. .
