[0002] Sea cucumber bait refers to phytoplankton, zooplankton, organic debris, benthic diatoms, etc. that can be eaten by sea cucumbers. The bait needs to be crushed during processing. However, due to the working mode and the single structure of the current sea cucumber bait mixing equipment, the following problems are caused: First, the mixing efficiency is low. There is a lack of mechanized mixing methods for bait mixing. Most of them use manual container mixing methods, which has low mixing efficiency; second, the mixing is uneven. The manual container mixing method easily causes uneven mixing of the bait, causing the problem of bait sedimentation; third, the bait quality is low.

[0011] The present invention realizes intermittent reciprocating drive through an intermittent reciprocating drive device, that is, gear A and gear B in the intermittent reciprocating drive device drive gear C to intermittently reciprocate. Specifically, when the equipment is working, the left and right motors respectively drive gear B and gear A to rotate through shaft A, and gear C is respectively meshed with gear A and gear B.
