In recent years, automation of the above-mentioned primary processing of crops, etc. has been progressing, but when carrying the crops into such automatic crop processing equipment, it is necessary to accurately carry the crops to a predetermined position.

However, crops such as onions do not have a constant shape, and even if they are placed on the belt of a belt conveyor, they tend to roll off or otherwise shift their position.

Also, it is extremely difficult to place the crop manually in advance on the belt in an accurate position.

On the other hand, it is not easy to smoothly transfer the crops transported by such a belt conveyor to the next processing station.

In view of these circumstances, the present invention is capable of automatically and accurately transporting crops to a predetermined position while holding them on a fixed transport path with simple operations, and furthermore, allows the crops to be transported to a predetermined position with ease. The purpose is to provide a device that can be smoothly transferred to other countries.

(Means for Solving the Problems) The present invention is a device for transporting crops while holding them on a certain transport route, the devices extending in a direction perpendicular to the transport route and arranged in parallel in the transport direction. a pair of front and rear rotating shafts, a left and right rotating wheel that is provided at symmetrical positions across the conveyance path on each rotating shaft and configured to rotate together with each rotating shaft, and a left rotating wheel. A pair of left and right endless moving members are spanned between each other and between the rotating wheels on the right side, and a plurality of pairs of outwardly open moving members are arranged at predetermined intervals on each moving member. and a receiving member;
The crop is conveyed while being placed between the left and right receiving members (Claim 1).

Furthermore, it would be more effective to attach each rotary wheel so that it can move in the axial direction relative to the rotary shaft, and to provide an interlocking mechanism that moves all the rotary wheels by the same amount at the same time.

First, according to the device according to claim 1, as both rotating shafts rotate in conjunction with each other, the left and right rotating wheels rotate, and the movable member is actuated, so that the receiver provided on the movable member is actuated. The members move at mutually equal speeds in the transport direction. In this state, by placing the crop between the receiving members, the crop is held in a stable state on the conveyance path and accurately conveyed to a predetermined position. Furthermore, since a space is secured between the receiving members, that is, directly below the transported crops, this space can be used to transfer the crops to another device.

Furthermore, according to the device according to claim 2, by moving each rotary wheel by an equal amount in the left and right direction by the interlocking mechanism,
The total mass allows the dimensions between the parts to be changed at the same time.

When they move in opposite directions, that is, in the direction toward and away from each other (see the arrows in the center of FIG. 1), the interlocking plates 88 fixed to each threaded cylinder 861 and 862 also move in the direction toward and away from each other. .

A clamping row 592 is attached to both front and rear ends of the interlocking plate 88 via a bracket 90, and each sprocket 66 is clamped from the left and right sides by the clamping roller 92, so that as the interlocking plate 88 moves, The left and right sprockets 66 and the chain member 75 hooked on the sprockets 66 also move together and move toward and away from each other.

As a result, the distances d (FIG. 3) between the receiving members 76 attached to the chain member 75 are all adjusted at the same time.

At this time, the distance d is set so that the crop 10 fits between the receiving members 76 from above and is supported in a stable manner, as shown in FIG.

In this state, the conveyance sprocket 12 shown in FIG. Sprocket 72 rotates.

Furthermore, this rotation is transmitted to the sprocket 68 of the crop conveyance device via the chain 70, and the sprocket 66 and the front and rear rotating shafts 63, 64 of the device rotate, and the chain member 75 begins to move in the crop conveyance direction. by this,
The eight receiving members 76 start moving at the same speed.

In this state, as shown in FIG.
