[0033] Preferably, the material agitating device 2 further comprises two vertical columns 201, the two vertical columns 201 are fixedly connected to the bottom of the cross beam 202 to form a frame structure, and are fixed to the outside of the mixing barrel 303; the hammer head 204 is connected with the output end of the vibrator 203, and sequentially passes through the mounting hole on the cross beam 202 and the hole 306 on the outer wall of the mixing barrel 303 to contact the stainless steel lining 305. The vibrator 203 of the material agitating device 2 can adjust the striking force to adapt to the cleaning requirements of different material thicknesses. Moreover, the hammer head 204 is fixed on the output shaft of the vibrator 203 through threaded connection or flange connection.
