The driving roller 4 and the driven roller 5 are sleeved with a conveying belt 6, the conveying belt 6 is used for driving the driving roller 4 to move when rotating and driving the driven roller 5 to rotate, the conveying belt 6 drives a part above the conveying belt 6 to move when moving, and the part is thrown out at the driven roller 5, so that the part moves in a parabolic manner. The inner wall of the screening chamber 101 is also provided with a fixing block 21, the fixing block 21 being located above the conveyor belt 6, the fixing block 21 being arranged to prevent parts above the conveyor belt 6 from overlapping together so that each part can move in a normal parabolic motion. The bottom of the machine body 1 is provided with a separation block 8, the separation block 8 is arranged into a triangular prism shape, and the top of the separation block 8 is an acute angle for separating normal parts from defective products. And a high-quality material outlet 9 is formed in the position, corresponding to the side surface of the first part 1 and the position, corresponding to the side surface of the second part 8, of the high-quality material outlet 9, and the position of the high-quality material outlet 9 is the outlet of a normal part. A defective product outlet 10 is formed in one side of the machine body 1 away from the high-quality material outlet 9, and the defective product outlet 10 is an outlet of defective products. The fan 11 is installed at the top of organism 1, and fan 11 is used for producing high-speed gas, and the output of fan 11 is connected with connecting pipe 12, and the other end of connecting pipe 12 is connected with the buffer chamber 13 of seting up in organism 1, still is provided with multiunit tuber pipe 14 in the organism 1, and buffer chamber 13 communicates with screening chamber 101 through multiunit tuber pipe 14, and tuber pipe 14 is arranged in blowing in the screening chamber 101 with high-speed gas. The blowing of high velocity gas affects the parabola of the part due to the weight of the part. The method is longer than the defective parts of the normal parts, and is lighter than the most recent defective parts of the normal parts. A first baffle 15 is fixedly connected in the screening chamber 101, and a second baffle 16, which is also mounted in the screening chamber 101, is provided on one side of the first baffle 15.
