During the up and down movement of the retrieval frame, the guide column and the locking wheel slide in the guide bar hole, so that when the moving seat moves to the lower position, the retrieval frame can be in the buffer channel to retrieve suspended objects. When the moving seat moves to the upper position, the retrieval frame is outside the buffer channel to unload suspended objects. With the cooperation of the two connecting arms on the left and right, intermittent retrieval of suspended objects can be achieved, which improves the retrieval efficiency.

[0016] 2. When water flows in the main body of the channel, the water wheel rotates, causing the water wheel shaft to rotate as well. The water wheel shaft drives the extrusion shaft to rotate via a belt. The cam on the extrusion shaft rotates as well, and the extrusion wheel can be forced to move downwards by the cam. Under the action of the tension spring, the connecting arm can rotate up and down with the connecting pin at the end as the center. The two connecting arms on the left and right can rotate up and down intermittently, achieving the purpose of using local materials and water power to save energy. Attached Figure Description
