The invention discloses a minced meat processing mechanism convenient to clean. The minced meat processing mechanism comprises a cylindrical processing cylinder, a crushing motor, a feeding hopper anda feeding cylinder, wherein the processing cylinder comprises a semicircular upper half shell and a semicircular lower half shell, and protruded edges are arranged at openings of the upper half shelland the lower half shell and are fixedly connected through a plurality of fastening bolts; the feeding hopper is arranged at the top of the upper half shell, and a hopper cover is mounted to the feeding hopper in a hinging manner; the crushing motor is mounted on one side of the processing cylinder, and the output end of the crushing motor is connected with a rotating shaft in the processing cylinder; and a plurality of meat mincing knives are mounted on the rotating shaft along the length direction of the rotating shaft, and a bowl-shaped feeding cylinder is fixedly connected to the bottom of the lower half shell. The minced meat processing mechanism has the beneficial effects that the processing cylinder is divided into the upper half shell and the lower half shell, so that the processing cylinder is very convenient to clean and disinfect; meanwhile, by virtue of the design of the meat mincing knives, meat can be efficiently minced; and the minced meat processing mechanism is simpleand stable in whole structure and has rich functions.
