A Chinese patent with authorization announcement number CN208194900U discloses a flour screening machine, which relates to the technical field of screening machines, including a screening drum, a chassis and a vibration motor. A filter plate and a collecting plate are arranged in the screening drum. A feed pipe is arranged at one end of the screening drum away from the chassis, a flap is rotatably arranged in the feed pipe, a coarse material pipe is arranged on the side wall of the screening drum, and a coarse material box is plugged in at one end of the coarse material pipe away from the screening drum; a fine material pipe is plugged in at the side wall of the screening drum, a spiral blade is rotatably arranged in the fine material pipe, and a driving assembly is arranged on the fine material pipe; the above device has the following shortcomings: flour is introduced from the feed pipe and flips into the screening drum through the flap, and the flour is light in weight, making it difficult to control the amount of flour pressed on the flap in the feed pipe. When the amount of flour is too little, the flap is difficult to flip. When too much flour enters the screening drum, the screening effect is poor. Utility Model Content
