[0029] The driving mechanism 7 includes a mounting frame 71, on which a motor 72 is fixedly mounted, on which a motor shaft of the motor 72 is fixedly mounted two driving pulleys 73, each driving pulley 73 is connected to a driven pulley 75 via a transmission belt 74, a bearing seat 76 is mounted on the rectangular frame 23, a rotating shaft 77 is fixedly mounted at the center of each driven pulley 75, the rotating shaft 77 is mounted in a bearing on the bearing seat 76, and the rotating shaft 77 is connected to the first connecting rod 24.

[0031] Working principle:

[0032] The first connecting rod 24 on the first screening mechanism 2 and the second screening mechanism 4 is driven to rotate by the driving mechanism 7 at the same time, and the first connecting rod 24, the second connecting rod 25 and the first screen plate 21 form a crank slider mechanism, and the first connecting rod 24, the second connecting rod 25 and the third screen plate form a crank slider mechanism, which drives the first screen plate 21 and the third screen plate to move back and forth on the support wheel 27, thereby driving the first screen plate 21 and the third screen plate to vibrate and screen the metal material.

[0033] The metal material to be screened is placed on the first screen plate 21, and the first screen plate 21 vibrates to screen the metal material. The screened metal material falls through the first screen hole 22 and enters the second screen plate 3. The metal material that cannot pass through the second screen hole falls into the first storage basket 5, and falls through the second screen hole into the second screening mechanism 4, and then is further screened through the third screen plate, and falls through the third screen hole into the second storage basket 6. The metal material is multi-stage screened by the first screening mechanism 2, the second screen plate 3 and the second screening mechanism 4, and the particle size of the metal material is screened by the three screening plates. After the screening is completed, the metal materials of four different particle sizes are stored on the first screen plate 21, the first storage basket 5, the third screen plate and the second storage basket 6, respectively, so that a more accurate particle size distribution can be obtained, thereby improving the screening accuracy. The three screening mechanisms can be customized according to different needs to meet the requirements of different materials and different screening purposes.
