[0002] Chinese mitten crab is also known as hairy crab. During the breeding process of Chinese mitten crab, various ingredients need to be added to the feed of Chinese mitten crab according to the growth stage of Chinese mitten crab to ensure that Chinese mitten crab obtains balanced nutrition and promotes its healthy growth. In the process of adding various ingredients to the feed of Chinese mitten crab, corresponding batching devices need to be used to mix the feed and various ingredients to promote the uniform mixing of the feed and various ingredients.

[0003] Although the existing batching device can mix feed and various ingredients, after the mixing process, the prepared feed is mostly discharged from the batching device through a discharge pipe. Although this discharge method can discharge the feed inside the batching device, during the use process, some residual feed often remains inside the device. In this process, not only part of the feed is wasted, but the residual feed inside the device is very easy to mold or breed bacteria, affecting the subsequent feed, and the use effect is not good.
