[0022] like Figures 5 to 9As shown, the feeding mechanism 3 is fixed on the top of the inner hanger 22, and the output end of the feeding mechanism 3 is connected to the input end of the vibrating screen 1 by a flexible channel, so that the vibrating screen 1 does not affect the feeding mechanism 3 when it swings. The same feeding mechanism can be used to feed the two vibrating screens, or two different feeding mechanisms can be used to feed the two vibrating screens. The feeding mechanism 3 includes a feeding box 31, a feeding roller 32 and a driving mechanism 33 for driving the feeding roller 32. The feeding box 31 is a rectangular parallelepiped, which includes two oppositely arranged end plates and two oppositely arranged side plates. The upper end of the end plate is bent outward to form a first upper connecting plate, and the lower end of the end plate is bent outward to form a first lower connecting plate. The upper end of the side plate is bent outward to form a second upper connecting plate, and the lower end of the side plate is bent outward to form a second lower connecting plate. The upper connecting plate forms an upper flange, and the lower connecting plate forms a lower flange. The feed box 31 is provided with two partitions 312, which divide the feed box 31 into three feeding channels 311 arranged side by side, including a middle feeding channel 311 and feeding channels 311 on both sides.

The surface of the rotating shaft 321 is provided with a number of longitudinal baffles 322 evenly distributed radially and circumferentially. A number of transverse baffles 323 are provided between adjacent longitudinal baffles 322. A feeding trough is formed between two adjacent longitudinal baffles 322 and two adjacent transverse baffles 323. The driving mechanism includes a gear 333 and a feeding motor 331 provided at the end of the feeding roller 32. The feeding motor 331 drives the gear 333 through a chain 334. The feeding motor 331 is connected to the reducer 332. The motor feeding 331 is fixed to the outside of the feeding box 31 through a bracket 335. By changing the number of sprocket teeth to achieve different transmission ratios, the feeding amount of the three layers is made uniform.

[0023] like Figure 1 As shown, the vibrating screen 1 is provided on an inner hanger 22. A vibrating mechanism is provided at the bottom of the inner hanger 22. The vibrating mechanism causes the inner hanger to swing and thereby drives the vibrating screen. The vibrating screen includes a vibrating box and a plurality of stacked and tilted screens. The input end of the screen is higher than the output end. The material on the screen is output from the input end to the output end by its own gravity and vibration, and is screened during the conveying process. The vibrating screen includes a product output vibrating screen, a powder output vibrating screen, and a miscellaneous material output vibrating screen. In this embodiment, a total of three groups of vibrating screens are provided. Each group of vibrating screens includes, from top to bottom, a product output vibrating screen, a miscellaneous material output vibrating screen, and a powder output vibrating screen. The three groups of vibrating screens correspond to the three feeding channels respectively. The three portions of material are fed into the three groups of vibrating screens for sorting.

[0024] like Figure 2 、 10 As shown, the discharging mechanism 4 includes a discharging box 41, a product output channel 42 provided in the discharging box 41 and connected to the product output vibrating screen, a powder output channel 44 provided in the discharging box 41 and connected to the powder output vibrating screen, and a miscellaneous material output channel 43 provided in the discharging box 41 and connected to the miscellaneous material output vibrating screen. One side of the discharging box 41 is hinged to the inner hanger 22 via a hinge 45, and the other side of the discharging box 41 is locked by a lock 46. The lock 46 includes a screw, one end of which is threadedly connected to the inner hanger, and the other end of the screw is provided with a pressure plate, which can press the discharging box 41. The discharge box 41 is provided with a reinforcement plate. The product output channel 42 is surrounded by a first circular tube, the miscellaneous material output channel 43 is surrounded by a second circular tube, and the powder material output channel 44 is surrounded by a third circular tube. The first circular tube, the second circular tube, and the third circular tube are all connected to the reinforcement plate, and the channels corresponding to each group of vibrating screen groups are interconnected. The discharge box 41 is trapezoidal in shape. The product output channel 42 in the discharge box 41 is located in the middle of the discharge box 41, and the miscellaneous material output channel 43 and the powder material output channel 44 are located on either side of the product output channel 42. An inspection port is provided on the front of the discharge box 41, and the discharge ports of the product output channel 42, miscellaneous material output channel 43, and powder material output channel 44 are located at the bottom of the discharge box 41. The vibration mechanism includes a vibration bracket, an eccentric block pivotally connected to the vibration bracket, and a vibration motor. The vibration motor drives the eccentric block to rotate through a belt. The eccentric block generates centrifugal force, which is transmitted to the vibrating screen, causing the material to move on the screen inside the vibrating screen, thereby obtaining a better screening effect.
