Crushing equipment for biological feed production

The utility model discloses crushing equipment for biological feed production, which relates to the technical field of feed processing and comprises a crushing tank and a crushing device mounted on the inner bottom wall of the crushing tank, a circular strip is welded in the middle of the crushing tank, and an arc-shaped rack is welded on the inner surface of the circular strip. Four different materials can be loaded into the material storage box at a time, specific feed can be selected according to needs to be discharged through the arrangement of the material distribution disc so that feed smashing can be completed, the situation that only one kind of feed can be fed at a time is avoided, and when multiple kinds of feed need to be treated, the feed can be smashed conveniently. According to the feed crushing device, multiple times of feeding and then discharging crushing operation need to be manually conducted in a segmented mode, time and labor are wasted, meanwhile, a connecting rod is in threaded connecti
