Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, specifically a vibrating screen for mining. Background Technology

[0002] Vibrating screens play a crucial role in ore processing. After ore is mined, it is often a mixture of particles of various sizes. Vibrating screens can classify the particles into different grades according to their size. Through precise grading and screening, it can ensure that each batch of ore products maintains a relatively consistent particle size distribution, thereby meeting the specific requirements of different users for ore particle size.

[0003] Existing ore vibrating screens, when in use, allow for thorough screening of ore by pouring it onto the screen mesh and using a vibrating motor. However, in actual use, the screen mesh's tilt angle is fixed and cannot be flexibly adjusted. This prevents the screen from being adjusted according to the ore's screening requirements, resulting in incomplete screening and affecting the screening quality. Alternatively, the ore may flow slowly on the screen mesh, clogging the screen openings and further impacting the screening effect. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a vibrating screen for mining, which solves the problem that when screening ore materials, the tilt angle of the screen is fixed and cannot be effectively adjusted. It also prevents the screen from being quickly adjusted according to the actual situation, resulting in insufficient screening of mineral materials and easy screen blockage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibrating screen for mining, comprising a base plate, two symmetrical fixed blocks fixedly connected to the upper surface of the base plate, a fixed rod fixedly connected between the two fixed blocks, a rotating block hinged to the fixed rod, a tilting plate fixedly connected to the upper surface of the rotating block, a screening frame provided above the tilting plate, a screen fixedly connected to the screening frame, a positioning block fixedly connected to the upper surface of the base plate, a hydraulic telescopic column fixedly connected to the positioning block, an adjusting block fixedly connected to the movable end of the hydraulic telescopic column, an oblique cut surface provided on the upper surface of the adjusting block, the adjusting block slidably connected to the tilting plate, a positioning frame fixedly connected to the lower surface of the screening frame, a vibrating motor fixedly connected to the positioning frame, support springs fixedly connected to the four corners of the lower surface of the screening frame, a support column fixedly connected to the end of the support spring away from the screening frame, and the support column fixedly connected to the tilting plate.

[0006] The beneficial effects of this utility model are as follows: by retracting the hydraulic telescopic column, the adjusting block moves, causing the adjusting block to slide with the tilting plate. The rotating block rotates on the fixed rod, lifting the tilting plate and causing it to tilt to the moving angle. In conjunction with the use of the vibrating motor, the ore material poured on the screen can be uniformly screened, improving the efficiency of ore screening, preventing clogging during screening, and increasing the flexibility of the vibrating screen.

[0008] As a further improvement to the above technical solution: a guide groove is provided on the upper surface of the base plate, a guide block is slidably connected in the guide groove, and the guide block is fixedly connected to the adjustment block;

[0009] The beneficial effects of this improvement are: by using guide grooves and guide blocks, the adjusting block can be guided, ensuring that the adjusting block remains sufficiently stable during the sliding process on the base plate and will not tilt or wobble.

[0010] In order to enable flexible movement of the vibrating screen;

[0017] As a further improvement to the above technical solution: a rubber pad is fixedly connected to the lower end face of the stabilizing block, and a plurality of evenly distributed grooves are formed on the lower end face of the rubber pad;

[0018] The beneficial effects of this improvement are: by using rubber pads and multiple grooves, a large frictional force can be generated between the rubber pads and the ground, thereby ensuring that the vibrating screen can freely shift and slide during use.

[0019] To improve the contact and sliding between the adjustment block and the flip plate, making adjustment easier;

[0020] As a further improvement to the above technical solution: the side of the flip plate that contacts the adjusting block is provided with an arc surface;

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0033] like Figures 1 to 5As shown in the figure, a mining vibrating screen provided by this utility model includes a base plate 1. Two symmetrical fixed blocks 11 are fixedly connected to the upper end face of the base plate 1. A fixed rod 12 is fixedly connected between the two fixed blocks 11. A rotating block 13 is hinged to the fixed rod 12. A tilting plate 14 is fixedly connected to the upper end face of the rotating block 13. The fixed blocks 11 and the fixed rod 12 can support the rotating block 13 and the tilting plate 14, ensuring the stability of the tilting plate 14. A screening frame 15 is provided above the tilting plate 14. A screen 16 is fixedly connected to the screening frame 15. A fixing block 17 is fixedly connected to the upper end face of the base plate 1. A hydraulic telescopic column 18 is fixedly connected to the fixing block 17. An adjusting block is fixedly connected to the movable end of the hydraulic telescopic column 18. 19. The upper end face of the adjusting block 19 has a beveled surface 20. The adjusting block 19 is slidably connected to the tilting plate 14. The lower end face of the screening frame 15 is fixedly connected to the positioning frame 21. The positioning frame 21 is fixedly connected to the vibration motor 22. The four corners of the lower end face of the screening frame 15 are fixedly connected to the support springs 23. The end of the support spring 23 away from the screening frame 15 is fixedly connected to the support column 24. The use of the four support columns 24 and their corresponding support springs 23 can support and stabilize the screening frame 15. The support column 24 is fixedly connected to the tilting plate 14. Under the extension and retraction of the hydraulic telescopic column 18, the adjusting block 19 moves, so that the adjusting block 19 slides between the tilting plate 14 and tilts the tilting plate 14 to flip it. The upper end face of the bottom plate 1 has a beveled surface 20. A guide groove 31 is provided, and a guide block 32 is slidably connected within the guide groove 31. The guide block 32 is fixedly connected to the adjusting block 19. Through the use of the guide groove 31 and the guide block 32, the adjusting block 19 can be guided, ensuring that the adjusting block 19 remains stable during movement and does not tilt or shake arbitrarily. Universal wheels 41 are fixedly connected to the four corners of the lower end face of the base plate 1. Through the use of the four universal wheels 41, the vibrating screen can be moved flexibly. Stabilizing rods 51 are fixedly connected to both sides of the base plate 1. Electric telescopic columns 52 are fixedly connected to the stabilizing rods 51. Stabilizing blocks 53 are fixedly connected to the movable ends of the electric telescopic columns 52. By extending the two electric telescopic columns 52, the corresponding stabilizing blocks 53 can be pulled towards the ground. The surface moves in the direction of the movement to support and stabilize the vibrating screen. A rubber pad 61 is fixedly connected to the lower end of the stabilizing block 53. The lower end of the rubber pad 61 has multiple evenly distributed grooves 62. With the use of two rubber pads 61, a large friction force is generated between the rubber pad 61 and the ground, thereby preventing the vibrating screen from shifting and shaking randomly. The side of the flip plate 14 that contacts the adjusting block 19 has an arc surface 71. The arc surface 71 allows the adjusting block 19 to contact the flip plate 14, making the adjusting block 19 slide better and preventing the adjusting block 19 from getting stuck. A handle 81 is fixedly connected to the upper end of the base plate 1. The movement direction of the vibrating screen can be controlled by the handle 81, making it easy for the operator to operate.

[0034] The working principle and usage process of this utility model are as follows: First, by using the handle 81 and four casters 41, the vibrating screen is moved to the desired position. Then, the extension of the two electric telescopic columns 52 moves the corresponding stabilizing blocks 53 downwards. The use of rubber pads 61 generates significant friction between the rubber pads and the ground, ensuring sufficient stability of the vibrating screen. Simultaneously, the retraction of the hydraulic telescopic column 18 causes the adjusting block 19 to slide on the base plate 1, sliding between the adjusting block 19 and the tilting plate 14, thereby lifting the tilting plate 14 and causing the rotating block 13 to rotate on the fixed rod 12. This allows for rapid adjustment of the tilt angle of the screening frame 15 and the screen 16. Combined with the use of the vibrating motor 22, the ore material poured onto the screen 16 is thoroughly screened, thus completing the entire usage process of the mining vibrating screen.
