An automatic feeding system for laboratory mice

Abstract

The application provides an automatic feeding system for experimental mice, and relates to the technical field of experimental animal feeding, and comprises a storage hopper, a feeder connected to the bottom of the storage hopper, a motor installed outside the feeder, a spiral conveying rod installed inside the feeder, a positioning lock sleeve sleeved to the bottom of the storage hopper, the positioning lock sleeve being located at the top of the feeder, a trigger rod and a vertical guide rod installed inside the storage hopper, and a fixing clamp connected to the outside of the storage hopper. The mouse feeding activity is sensed by the infrared switch, the motor pushes the feed particles to move through the spiral conveying rod, and the feed particles are moved to the feeding opening area, so that the mouse feeding activity is facilitated. The mouse feeding operation is usually periodically fed by manual mode, the mouse is naturally timid and afraid of being startled, and is very sensitive to the external environment, and is easily disturbed by strangers, and the frequent feeding operation easily causes adverse effects on the mouse.
