[0025] 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 scope of protection of the present utility model.

[0026] Please see Figures 1-5As shown, a screen plate for a mining crusher includes a base 1, and an adjustment assembly 2 is provided on the top of the base 1. The adjustment assembly 2 includes a support frame 21 installed on the top of the base 1. Two connecting rods 22 are hinged to the top of the support frame 21. A separation bucket 23 is fixedly installed on the top of the two connecting rods 22. A vibrator 25 is fixedly installed on the bottom of the separation bucket 23. A groove is opened at the bottom of the separation bucket 23, and a separation channel 24 is fixedly installed through the groove. A screen bucket 26 is fixedly installed on the top of the separation bucket 23. A screen mesh 27 is movably installed on the top of the screen bucket 26. A connecting channel 28 is fixedly installed on one side of the screen bucket 26.

[0027] During operation, the vibrator 25 generates vibration and transmits it to the separation hopper 23 and the screen hopper 26. The material enters the screen hopper 26 through the connecting channel 28 and is screened by the screen 27. The material that meets the particle size requirements falls into the separation hopper 23 and is discharged through the separation channel 24. The connecting rod 22 hinges the separation hopper 23 to the support frame 21 to ensure the stability of the separation hopper 23 during vibration and angle adjustment.

[0028] Furthermore, the adjustment assembly 2 also includes a fixing plate 29, which is fixedly installed on the top of the support frame 21. A servo motor 31 with a self-locking function is fixedly installed on one side of the fixing plate 29. A first pulley 32 is fixedly installed at the output end of the servo motor 31. A transmission belt 33 is connected to the outer surface of the first pulley 32. A second pulley 34 is connected to the other side of the transmission belt 33.

[0029] During operation, the servo motor 31 starts and drives the first pulley 32 to rotate, which in turn drives the second pulley 34 to rotate synchronously through the transmission belt 33, thus realizing power transmission. The self-locking function of the servo motor 31 can maintain the current transmission state when the machine stops, preventing the angle of the separation bucket 23 from shifting due to vibration.

[0030] Furthermore, the adjusting assembly 2 also includes a ball screw 35, one end of which is fixedly mounted with a second pulley 34. The ball screw 35 is rotatably mounted on one side of the fixed plate 29. The ball screw 35 passes through and is threadedly connected to a ball nut 36. A lifting plate 37 is fixedly mounted at the bottom of the ball nut 36.

[0031] During operation, the second pulley 34 drives the ball screw 35 to rotate on the fixed plate 29, and the ball nut 36 moves linearly along the ball screw 35, thereby driving the lifting plate 37 to move up and down, providing power for the angle adjustment of the separating bucket 23.

[0032] Furthermore, two adjusting rods 39 are hinged to one side of the lifting plate 37, and the other ends of the two adjusting rods 39 are hinged to the bottom of the separation bucket 23.

[0033] During operation, as the lifting plate 37 moves up and down, the adjusting rod 39 pushes or pulls the separating bucket 23 through the hinge point. Combined with the hinge support of the connecting rod 22, the separating bucket 23 rotates around the connecting rod 22, thereby adjusting the tilt angle to meet the screening requirements of different materials.

[0034] Furthermore, two limiting rods 38 are fixedly installed at the bottom of the fixed plate 29. The bottom ends of the two limiting rods 38 are fixedly installed at the top of the support frame 21. The lifting plate 37 is slidably installed through the two limiting rods 38.

[0035] During operation, the limit rod 38 guides and limits the movement of the lifting plate 37, preventing the lifting plate 37 from rotating or deviating during movement, ensuring that the lifting plate 37 moves smoothly in the vertical direction, and ensuring the accuracy of the angle adjustment of the separation bucket 23.

[0036] Furthermore, the base 1 includes a mounting plate 11, and four fixing rods 12 are fixedly mounted on the top of the mounting plate 11. Each of the four fixing rods 12 is fixedly mounted with a support plate 13. Each of the four support plates 13 is fixedly mounted with a spring 14. Each of the four springs 14 is fixedly mounted with a movable plate 15. The four movable plates 15 are slidably mounted on the outer surface of the fixing rods 12. The top of the four movable plates 15 is fixedly mounted on a support frame 21 on the adjustment assembly 2.

[0037] During operation, the mounting plate 11 is used to fix the equipment under the crusher; after the impact force generated by the vibration is transmitted to the support frame 21, the movable plate 15 slides down along the fixed rod 12 and compresses the spring 14. The elastic deformation of the spring 14 absorbs the vibration energy, realizes buffering and shock absorption, and reduces the damage of vibration to the equipment connecting parts.

[0038] Working principle: The tilt angle of the separation hopper 23 is adjusted by the servo motor 31. The servo motor 31 drives the first pulley 32, the transmission belt 33 and the second pulley 34 to drive the ball screw 35 to rotate, so that the ball nut 36 drives the lifting plate 37 to move up and down along the limit rod 38. The lifting plate 37 pushes the separation hopper 23 to rotate around the connecting rod 22 to a suitable angle through the adjusting rod 39. The servo motor 31 self-locks to keep the angle stable. The vibrator 25 is started and adjusted to the appropriate vibration parameters. The material enters the screen hopper 26 through the connecting channel 28. Under the action of vibration, the material that meets the particle size falls into the separation hopper 23 through the screen 27 and is discharged through the separation channel 24. The large particle size material is retained in the screen hopper 26. During the vibration, the spring 14 of the base 1 continuously buffers and dampens the shock through the sliding of the movable plate 15, reducing equipment wear.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
