Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides an embodiment of a multi-hole polyurethane rubber screen plate, comprising a screen frame 1, a screen plate body 2, a bottom support frame 3, and rubber elastic balls 13. Elastic ropes 12 are symmetrically fixedly connected to both sides of the rubber elastic balls 13. Connecting rods 11 are uniformly fixedly installed on the inner side of the screen frame 1. The end of the elastic rope 12 away from the rubber elastic balls 13 is fixedly installed on the connecting rod 11. Guide arc plates 14 are symmetrically fixedly connected to both sides of the top of the screen plate body 2. Screen grooves 15 are uniformly opened through the top of the screen plate body 2. A reinforcing connecting plate 16 is provided at the top of the screen plate body 2. The reinforcing connecting plate 16 is designed to be inclined. The inclined design of 6 maximizes the uniformity of material passing through the 15-screen. The screen plate body 2 is evenly fixed on the top of the main screen frame 1, and a rubber elastic ball 13 is set at the center of the bottom of each screen plate body 2. During the vibration process, under the elastic force of the elastic rope 12 and the weight of the rubber elastic ball 13, the rubber elastic ball 13 moves up and down continuously. When the rubber elastic ball 13 moves upward and contacts the bottom of the screen plate body 2, it strikes the screen plate body 2. The striking of the rubber elastic ball 13 can shake out foreign objects that are adhered or blocked inside the screen groove 15, thereby reducing the risk of blockage of the screen groove 15.

[0022] Side baffles 4 are symmetrically fixedly connected to the top two sides of the main frame 1 of the screen. A rotating shaft 6 is rotatably connected to the top center of the side baffles 4. Two eccentric wheels 5 are symmetrically fixedly connected to the rotating shaft 6. A servo motor 7 is fixedly installed on the outer side of one of the side baffles 4. The drive end of the servo motor 7 is fixedly installed on one end of the rotating shaft 6. The drive end of the servo motor 7 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the eccentric wheel 5 to rotate. Since the center of gravity of the eccentric wheel 5 is not in the center, the rotating shaft 6 shakes continuously.

[0023] The main frame 1 of the screen is designed with an inclination. Four support legs 8 are symmetrically fixed to both ends of the bottom of the main frame 1, and the bottom ends of the four support legs 8 are located on the same horizontal plane. A sliding column 9 is fixedly connected to the bottom end of the support leg 8. A buffer spring 10 is nested on the outside of the sliding column 9. A locking plate is fixedly installed at the bottom end of the sliding column 9 to prevent the sliding column 9 from sliding out of the top of the bottom support frame 3 and tipping over. The bottom end of the sliding column 9 is slidably connected to the top of the bottom support frame 3. The top end of the buffer spring 10 is close to the bottom end of the support leg 8, and the bottom end of the buffer spring 10 is close to the top of the bottom support frame 3. The buffer spring 10 applies cushioning to prevent the bottom support frame 3 and the support leg 8 from colliding and causing damage.

[0024] Working Principle: During operation, the servo motor 7 is first started. The drive end of the servo motor 7 drives the rotating shaft 6 to rotate, which in turn drives the eccentric wheel 5 to rotate. Because the center of gravity of the eccentric wheel 5 is not in the center, the rotating shaft 6 continuously wobbles. The rotating shaft 6 transmits this wobbling to the main screen frame 1. The wobbling of the main screen frame 1 causes the sliding support column 9 to wobble. Since the sliding support column 9 is slidably connected to the top of the bottom support frame 3, it is limited to wobbling vertically. Furthermore, the buffer spring 10 is located between the support leg 8 and the bottom support frame 3. When the main screen frame 1 drives the support leg 8 to wobble up and down, the buffer spring 10 cushions the movement, preventing impact between the bottom support frame 3 and the support leg 8. Then, the material is poured onto the top of the screen plate body 2. Due to the wobbling of the main screen frame 1, the screen plate body 2 wobbles, causing the material on the top of the screen plate body 2 to vibrate and roll downwards, simultaneously performing screening and sprinkling. Material falling onto the top of the screen plate body 2 is guided by the guide arc plate 14 to the inner side of the top of the screen plate body 2 and screened through the screen groove 15. This prevents the material from rolling down directly without passing through the screen groove 15. Moreover, due to the inclined design of the reinforcing connecting plate 16, the material can pass through the screen groove 15 for screening during the rolling process. When the screen frame 1 shakes up and down, it drives the connecting rod 11 to shake. The shaking of the connecting rod 11 drives the elastic rope 12 to shake. The shaking of the elastic rope 12 drives the rubber elastic ball 13 to move up and down. Under the elastic force of the elastic rope 12 and the weight of the rubber elastic ball 13, the rubber elastic ball 13 moves up and down continuously. When the rubber elastic ball 13 moves upward and contacts the bottom of the screen plate body 2, it strikes the screen plate body 2. The striking of the rubber elastic ball 13 can shake out foreign objects that are adhered or blocked on the inner side of the screen groove 15, thereby reducing the risk of blockage in the screen groove 15 and improving the durability of the device.
