The throwing plate 381 may also be curved, and the direction of the throwing plate 381 may form an acute angle with the axis of the throwing portion 38. When the throwing part 38 rotates, the throwing plate 381 rotates with the throwing part 38, and in the process, the throwing plate 381 can lift up the straw and the residual film in the throwing part 38 and then throw out the straw and the residual film. One end and the other end of the screening cylinder 3 are rotationally connected with the screening cylinder rack 1, and the screening cylinder rack 1 is provided with a screening driving mechanism for driving the screening cylinder 3 to rotate around the axis of the screening cylinder rack 1; as shown in fig. 2, the side wall of one end of the sieving cylinder 3 is provided with a circular first sieving hole 31, the side wall of the other end of the sieving cylinder 3 is provided with a long-strip second sieving hole 35, the other end of the sieving cylinder 3 is connected with the suction fan 5 through the air pipe 4, as shown in fig. 5, the impeller of the suction fan 5 comprises a circular mounting plate 54, one end surface of the mounting plate 54 is provided with a plurality of air suction blades 55, the air outlet of the suction fan 5 is connected with the membrane box 6, and the upper part of the membrane box 6 is in a net shape.
