Here, an example of preferable control operation of the slide mechanism 40 and the elevating mechanism 50 by the control unit 60 will be described in detail. First, as shown in FIG.
The delivery conveyor 20 is stopped at the right slide limit position, the left container placement part 30 is stopped at the highest position, and the right container placement part 30 is stopped at the lowest position.

Next, the transport conveyor 10 is driven and rotated, and the delivery conveyor 20 is moved to the left delivery side end 20a.
Drive to rotate in the direction. Therefore, the farm products carried into the carry-in side end of the carry conveyor 10 are carried on the carry conveyor 10, and the send-out conveyor 2 is fed from the send-side end 10a.
No. 0 belt, is further conveyed by the delivery conveyor 20 to the left delivery side end 20a, and is delivered from the delivery side end 20a into the container 31 on the container placing section 30.

Since the delivered agricultural products roll down along the slanted inner surface of the container 31, the agricultural products hardly fall vertically. Therefore, the corners of the container 31 on the delivery conveyor 20 side are accumulated without being damaged.

Then, when the distance h between the upper surface of the accumulated agricultural products and the agricultural product detection unit 21 on the delivery side end 20a side on the left side of the delivery conveyor 20 becomes within the set value, the rod of the lifting mechanism 50 is contracted. , Container placement unit 30
Descends while rotating by a predetermined amount (see FIG. 3B). Therefore, the distance h between the top surface of the crop and the crop detection unit 21
Exceeds the set value, and agricultural products are further accumulated in the container 31.

When the distance h between the upper surface of the accumulated agricultural products and the agricultural product detecting portion 21 becomes within the set value again, the rod of the elevating mechanism 50 is further contracted and the container mounting portion 30 is located in the same manner as above. It descends while rotating a fixed amount (Fig. 3 (c)).

The above-described operation pattern in which the container placing section 30 descends while rotating by a predetermined amount is set in four stages in the present embodiment. That is, the container placement unit 30
Is lowered four times while rotating a predetermined amount to reach the lowest position where the bottom surface portion 30a is landed on the ground (FIG. 3).
(See (d)). The set value of the interval h between the upper surface of the accumulated agricultural products and the agricultural product detection unit 21 is, in the present embodiment,
It is set to about 30 cm.

Even after the bottom surface portion 30a of the container placing portion 30 lands on the ground according to the above operation pattern, the delivery of the agricultural products from the delivery conveyor 20 is continued. Then, at this lowest position, when the distance h between the upper surface of the accumulated agricultural products and the agricultural product detection unit 21 is within the above-mentioned set value, the slide mechanism 40 is driven to cause the transfer conveyor 20 to move the transfer-side end part thereof. It slides in the direction of 20a (leftward) by a predetermined amount (see FIGS. 4A and 4B). Therefore, the farm products delivered from the delivery conveyor 20 roll down on the slope on the left side formed by the farm products accumulated in the container 31. Then, when the agricultural products are accumulated on the left side of the slope and the distance between the upper surface and the agricultural product detection unit 21 is within the above-mentioned set value, the delivery mechanism 20 is driven by driving the slide mechanism 40 again. It slides by a predetermined amount in the direction of the side end 20a (leftward) (see FIGS. 4 (c) and 4 (d)).

The above operation pattern for accumulating agricultural products and sliding the delivery conveyor 20 is repeated several times. When the delivery conveyor 20 reaches the left-side slide limit position detected by the limit switch 41, the right-side container placing section 30 is rotated by its elevating mechanism 50 and ascends to reach the highest position. At the same time, the delivery conveyor 20 is driven in reverse. Therefore, the agricultural products on the delivery conveyor 20 are delivered to the container 31 on the container placement unit 30 on the right side. The right container placement part 30 is the left container placement part 30 described above.
In the same manner as the operation pattern of No. 2, the conveyor 31 descends to the lowest position while gradually rotating by a predetermined amount in accordance with the accumulation state of the agricultural products in the container 31, and then the delivery conveyor 20 responds to the accumulation state of the agricultural products. And slide to the right in steps by a predetermined amount.

Therefore, while the work of bringing in the crops into the container 31 on one of the container placement sections 30 is being carried out, the work of replacing the container 31 on the other container placement section 30, that is, a predetermined amount of the crops is carried out.
