Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a mining vibrating screen with a cleaning function. Background Art

[0002] With the development of industrial technology and the increasing requirements for production efficiency, the performance requirements of mining vibrating screens are also constantly improving. Developing a vibrating screen with a cleaning function has become an inevitable trend in the industry. This kind of vibrating screen not only improves the screening efficiency but also reduces the maintenance cost, which is of great significance for improving the economic benefits of the entire production line.

[0003] In the screening process of traditional vibrating screens, materials are first evenly transported to the screen surface of the vibrating screen through a feeding device. The vibrating screen generates a specific vibration mode, such as linear vibration, circular vibration or composite vibration, through its vibration mechanism, causing the materials on the screen surface to jump or slide. Due to the limitation of the screen aperture, larger particles cannot pass through the screen holes and remain on the upper layer of the screen surface, becoming the oversize product, while smaller particles can pass through the screen holes and fall to the lower layer of the screen surface, becoming the undersize product. After screening, the oversize product and the undersize product are discharged from both ends of the screen surface respectively.

[0004] However, in the screening process of traditional vibrating screens, the screen is easily blocked by fine particles in the materials, affecting the screening efficiency and screening accuracy. Therefore, it is necessary to stop the machine regularly for cleaning, which not only increases the maintenance cost but also reduces the production efficiency. For this reason, a mining vibrating screen with a cleaning function is proposed to solve the above problems. Content of the Utility Model

Detailed implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Refer to Figure 1 - Figure 3 , an embodiment provided by the present invention: a mine vibrating screen with a cleaning function, including an outer shell 1, a feed pipe 2 fixedly connected inside the outer shell 1, a discharge pipe 3 fixedly connected to the bottom of the outer shell 1, a cylinder 4 fixedly connected inside the outer shell 1, a pusher block 5 fixedly connected to the output end of the cylinder 4, a connecting block 7 slidably connected inside the outer shell 1, a first slide post 6 fixedly connected inside the connecting block 7, the outer wall of the first slide post 6 slidably connected inside the pusher block 5, cylinders 8 fixedly connected to both sides of the outer wall of the connecting block 7, a slide groove 9 opened inside the outer shell 1, the outer wall of the cylinder 8 slidably connected inside the slide groove 9, a screening mesh 10 arranged inside the outer shell 1, a first motor 11 fixedly connected inside the connecting block 7, a rotating brush 12 fixedly connected to the output end of the first motor 11, a third motor 26 fixedly connected inside the connecting block 7, a driving sprocket 27 fixedly connected to the output end of the third motor 26, a driven sprocket 28 rotatably connected inside the connecting block 7, a chain 29 arranged between the driving sprocket 27 and the driven sprocket 28, cleaning hoops 30 fixedly connected to both sides of the outer wall of the chain 29, the rotating brush 12 slidably connected inside the cleaning hoops 30, a discharge port 31 opened inside the outer shell 1, a base 13 fixedly connected to the bottom of the outer shell 1, a guiding component arranged inside the base 13, and the guiding component is used for guiding the lifting component to move along a preset route;

[0026] Specifically, when using the mining vibrating screen with a cleaning function, first start the cylinder 4. The start of the cylinder 4 will push the push block 5 to move to the lower right side. This action is the starting point of the entire cleaning process. As the push block 5 moves, it will drive the connecting block 7 to move accordingly. The movement of the connecting block 7 will further drive the cylinder 8 to move along the slide 9. During the movement of the connecting block 7, it will first move significantly to the lower right. This action enables the roller brush 12 and the connecting block 7 to contact the screening net 10, thereby cleaning the screening net 10. After the cleaning work is completed, the cleaned material on the screening net 10 will be discharged from the discharge port 31. Next, start the motor three 26. The operation of the motor three 26 will drive the active chain The wheel 27 rotates, and at this time, the driven sprocket 28 also starts to rotate driven by the chain 29. During the rotation process, the chain 29 will drive the cleaning hoop 30 to clean the surface of the roller brush 12 to ensure the cleanliness of the surface of the roller brush 12 so as to facilitate the next cleaning work. Finally, through the contraction action of the cylinder 4, the cleaning component is retracted and raised a certain distance to ensure that the cleaning component will not hinder the normal operation of the screening net 10. In this way, the entire cleaning process is completed, and the mining vibrating screen can continue to perform screening operations to maintain screening efficiency and screening quality. Through this design, the mining vibrating screen can not only efficiently complete the screening task, but also reduce manual intervention through the automated cleaning mechanism, thereby improving operating efficiency and safety.

[0027] Reference Figure 3 - Figure 5 The guide assembly includes a slide post 14 and a slider 15, the outer wall of the slide post 14 is slidably connected to the inside of the slider 15, and the bottom of the slide post 14 is fixedly connected to the inside of the base 13;

[0028] Specifically, in the mining vibrating screen with a cleaning function, the slide column 14 can strictly limit the moving direction and path of the lifting plate 25, so that it can be accurately lifted and lowered along a preset route, avoiding deviation, shaking or irregular movement, thereby ensuring its operating accuracy.

[0029] Reference Figure 3 - Figure 5 The base 13 is slidably connected with a slider 23 inside, and the slider 23 is rotatably connected with a transmission rod 22 inside. The bottom of the slider 15 is fixedly connected with a lifting plate 25, and one side of the outer wall of the transmission rod 22 is fixedly connected with a gear 21. The lifting plate 25 is slidably connected with a transmission plate 19, and the top of the transmission plate 19 is fixedly connected with a toothed plate 20, and the toothed plate 20 is meshed with the gear 21. The lifting plate 25 is fixedly connected with a motor 21, and the output end of the motor 16 is fixedly connected with a gear 17. One side of the outer wall of the transmission plate 19 is fixedly connected with a toothed plate 18, and the gear 17 is meshed with the toothed plate 18. The bottom of the lifting plate 25 is rotatably connected with a walking wheel 24;

[0030] Specifically, when it is necessary to move the mining vibrating screen device with cleaning function, first start the second motor 16. The second motor 16 serves as the power source of the moving mechanism. Its operation drives the first gear 17 to start rotating. The rotation of the first gear 17 transmits power to the transmission plate 19 through the transmission of the first toothed plate 18 meshing with it. The transmission plate 19 moves to the left under the drive of the first gear 17. This moving action is further transmitted to the two second toothed plates 20. Under the action of the transmission plate 19, the second toothed plates 20 rotate in opposite directions respectively. Due to the different positions of the second toothed plates 20, their rotation directions are opposite. This design ensures the balance and stability of the transmission. The rotation of the second toothed plates 20 drives the rotation of the transmission rod 22. The rotation of the transmission rod 22 transmits force to the lifting plate 25 through the second slider 23. The lifting plate 25 is forced to descend under the action of the transmission rod 22. This descending action causes the lifting plate 25 to drive the traveling wheels 24 to descend. When the traveling wheels 24 descend to contact the ground, the entire device is lifted, so that the weight of the device no longer directly acts on the ground, but is borne by the traveling wheels 24. At this time, the movement of the device becomes easy, and the operator can easily push or pull the device to adjust or move its position. This design not only improves the moving efficiency of the device, but also ensures the stability and safety during the movement. Through this automated and mechanized moving method, the convenience and efficiency of the operation are greatly improved.

[0031] Working principle: When using the mine vibrating screen with cleaning function, first start the cylinder 4. The cylinder 4 pushes the push block 5 to move towards the lower right side. When the push block 5 moves, it drives the connecting block 7 to move, and the connecting block 7 drives the cylinder 8 to move. The cylinder 8 moves along the chute 9. Therefore, when the connecting block 7 moves, it first moves significantly towards the lower right side, causing the rotary brush 12 and the connecting block 7 to contact the screening mesh 10, clean it, and discharge it from the discharge port 31. After the cleaning is completed, start the motor three 26. The motor three 26 drives the driving sprocket 27 to rotate. At this time, the driven sprocket 28 is driven by the chain 29 and also rotates. During this process, the chain 29 drives the cleaning hoop 30 to clean the surface of the rotary brush 12, facilitating the next cleaning. Finally, through the contraction of the cylinder 4, the cleaning assembly is retracted and raised a certain distance without interfering with the work of the screening mesh 10. When the device needs to be moved, the motor two 16 can be started. Subsequently, the motor two 16 drives the gear one 17 to rotate. Through the transmission of the toothed plate one 18, the transmission plate 19 moves to the left. The movement of the transmission plate 19 drives the two toothed plates two 20 to move respectively, causing the two gears two 21 to be forced to rotate. It should be noted that because the positions of the two toothed plates two 20 are different, the rotation directions of the two toothed plates two 20 are opposite. When the toothed plate two 20 rotates, it drives the transmission rod 22 to rotate, and then the slider two 23 moves away from each other, causing the lifting plate 25 to descend under the action force. At this time, the lifting plate 25 drives the walking wheel 24 to descend until the walking wheel 24 touches the ground and jacks up the device. Subsequently, the device can be easily moved.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
