one end of the feeding pipe 2e is communicated with the first through hole 2b1, and the other end of the feeding pipe 2e extends to the river crab culturing box.

When the first driver 2d drives the valve plate 2c to move so that the first through hole 2b1 and the second through hole 2c1 coincide at the same time, river crab feed contained in the container 2b enters the feeding pipe 2e through the first through hole 2b1 and the second through hole 2c1 and finally slides into the river crab culture box, and therefore automatic feeding is achieved.

Further, as shown in fig. 23, in order to facilitate the feeding pipe 2e to feed the river crab culturing box, the following technical scheme is provided:

The distance between the second through holes 2c1 arranged in the clockwise direction and the axis of the valve plate 2c gradually increases, and the first driver 2d drives the valve plate 2c to rotate in the counterclockwise direction, so that the second through holes 2c1 closer to the axis of the valve plate 2c coincide with the first through holes 2b1 earlier; the second through hole 2c1 closer to the axial center of the valve sheet 2c is provided at a lower position of the feed pipe 2e communicating therewith. Therefore, the feeding pipe 2e which enters the river crab feed later is arranged at a high position, and the feeding pipe 2e which enters the river crab feed earlier is arranged at a low position, so that the feed which enters the feeding pipe 2e earlier falls for a longer time, and the feed which enters the feeding pipe 2e later falls for a shorter time, and each feeding pipe 2e can discharge the feed simultaneously.
