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 are simultaneously overlapped, the 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, so that automatic feeding is realized.

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