Abstract
Description
Technical Field
[0001] This utility model relates to the field of solid waste resource utilization technology, specifically a mobile coal gangue aggregate screening device. Background Technology
[0002] In the field of solid waste resource utilization, coal gangue, as a large amount of solid waste generated during coal mining and washing, is of great significance for environmental protection and sustainable resource utilization through comprehensive treatment and resource utilization. Screening of coal gangue aggregate is a key link in converting it into usable resources. Through screening, aggregates of different particle sizes can be obtained.
[0003] In existing technologies, there is usually a lack of flexible mobility, making relocation difficult. When it is necessary to change the work site, a lot of manpower, material resources and time are often required for disassembly, transportation and reinstallation, which seriously affects production efficiency. Even if some devices are equipped with mobility devices, stability is difficult to guarantee when working in a fixed position. The strong vibration generated by the vibrating screen during operation may cause the raised part of the support leg to suddenly fall due to vibration, causing serious damage to the equipment, increasing equipment maintenance costs, and causing production interruption, further affecting production efficiency.
[0004] In view of the above, this application is hereby submitted. Utility Model Content
[0005] The purpose of this invention is to provide a mobile coal gangue aggregate screening device to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a mobile coal gangue aggregate screening device, including a mobile chassis. Four liftable support components are installed at the bottom of the mobile chassis. One of the liftable support components includes a support leg fixedly connected to the bottom of the mobile chassis. A toothed plate is fixedly connected to the bottom of the support leg. A fixed outer shell is slidably connected to the outer wall of the toothed plate. A support frame is fixedly connected to the inner wall of the fixed outer shell. A spiral-patterned rotating disk is rotatably connected to one side of the outer wall of the support frame. A gear is fixedly connected to the outer wall of the spiral-patterned rotating disk on the side away from the support frame. A pressure rod is rotatably connected to the middle of the gear. A traction rod is rotatably connected to one side of the top of the pressure rod. A moving wheel is fixedly connected to the bottom of the fixed outer shell.
[0007] Furthermore, two supports are installed at the top of the mobile chassis, and a screen mounting shell is fixedly connected to one side of the two supports. Three screen plates are installed on the inner wall of the screen mounting shell.
[0008] Furthermore, four sets of vibration damping components are installed on the outer wall of the screen plate. Each set of vibration damping components includes a mounting block that is fixedly connected to the outer wall of one side of the screen mounting housing. A rubber block is installed at the bottom of the mounting block, and a spring is installed at the bottom of the rubber block.
[0009] Furthermore, two vibration motors are installed on one side of the outer wall of the screen mounting housing, and one side of each vibration motor is fixedly connected to the screen mounting housing.
[0010] Furthermore, one side of the outer wall of the toothed plate is meshed with the spiral-patterned rotating disk, the bottom end of the support leg is fixedly connected to the top end of the toothed plate, one side of the inner wall of the traction rod is rotatably connected to the top end of the pressure rod, and a toothed block is installed on the outer wall of the traction rod away from the pressure rod, and one side of the outer wall of the toothed block is in contact with the gear.
[0011] Furthermore, the aperture size of the three screen plates is graded according to the particle size of the coal gangue, decreasing sequentially from top to bottom.
[0012] Furthermore, one end of the spring is fixedly connected to the bottom end of the rubber block, and the other end of the spring is fixedly connected to the top end of the bracket.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] By utilizing the adjustable support components, the support legs are locked after each adjustment, reducing the possibility of the support legs loosening and falling due to vibration. This reduces the additional impact and stress on the equipment caused by vibration, lowers the equipment failure rate, and extends the equipment's service life.
[0015] The four adjustable support components work together to quickly level the equipment when one side of the ground is higher than the other. This eliminates the need for large-scale site modifications, shortens installation time, and improves installation efficiency. Attached Figure Description

[0024] 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.
[0025] Please see Figures 1-7This utility model provides a technical solution: a mobile coal gangue aggregate screening device, including a mobile chassis 1. The mobile chassis 1 serves as a support platform for the components, providing installation positions for other parts and ensuring the overall structural stability and integrity of the components. Four liftable support components are installed at the bottom of the mobile chassis 1. These four liftable support components are individually adjustable in height to adapt to uneven working sites, ensuring the components remain horizontally stable under various terrain conditions, thus improving the versatility and adaptability of the device. One of the liftable support components includes a support leg 2 fixedly connected to the bottom of the mobile chassis 1. A toothed plate 3 is fixedly connected to the bottom of the support leg 2. A fixed outer shell 4 is slidably connected to the outer wall of the toothed plate 3, providing a good guiding environment for the sliding of the toothed plate 3 and ensuring the stability of the support leg. 2. Smooth lifting and lowering movement: A support frame 5 is fixedly connected to the inner wall of the fixed outer shell 4. A spiral patterned rotating disk 6 is rotatably connected to one side of the outer wall of the support frame 5. The support frame 5 provides an installation position for the spiral patterned rotating disk 6 and ensures the stability of the spiral patterned rotating disk 6 during rotation. A gear 7 is fixedly connected to the outer wall of the spiral patterned rotating disk 6 away from the support frame 5. A pressure rod 8 is rotatably connected to the middle of the gear 7. A traction rod 9 is rotatably connected to the top of the pressure rod 8. By pressing the pressure rod 8, the traction rod 9 is rotated, thereby driving the gear 7 to rotate. Because the gear 7 is fixedly connected to the spiral patterned rotating disk 6, when the gear 7 rotates, the spiral patterned rotating disk 6 will rotate synchronously, thereby driving the toothed plate 3 that meshes with it to lift and lower. A movable wheel 10 is fixedly connected to the bottom end of the fixed outer shell 4.
[0026] See Figure 1 , Figure 6 Two supports 11 are installed at the top of the mobile chassis 1. A screen mounting shell 12 is fixedly connected to one side of the two supports 11. The two supports 11 provide stable support for the screen mounting shell 12, so that the screen mounting shell 12 can maintain a suitable height and position for easy screening. Three screen plates 13 are installed on the inner wall of the screen mounting shell 12. The screen mounting shell 12 provides a stable mounting base for the screen plates 13, ensuring the stability and accuracy of the screening process. The three screen plates 13 are installed on the inner wall of the screen mounting shell 12 from top to bottom according to the size of the screen holes. Under the vibration generated by the vibrating motor 17, the input coal gangue aggregate is graded and screened. Aggregates of different particle sizes are collected by passing through screen plates 13 with different screen hole sizes.
[0027] See Figure 7Four sets of vibration damping components are installed on the outer wall of the screen plate 13. Each set of vibration damping components includes a mounting block 14 that is fixedly connected to one side of the outer wall of the screen mounting shell 12. The mounting block 14 is fixedly connected to one side of the outer wall of the screen mounting shell 12, connecting the vibration damping component and the screen mounting shell 12 into a whole. A rubber block 15 is installed at the bottom of the mounting block 14, and a spring 16 is installed at the bottom of the rubber block 15. The rubber block 15 has a certain elasticity and can undergo elastic deformation when the screen plate 13 is subjected to vibration and impact, absorbing part of the vibration energy and playing a preliminary vibration damping and buffering role. When the screen plate 13 is subjected to a large vibration and impact, the spring 16 is compressed and stores elastic potential energy. When the vibration and impact force decreases, the spring 16 recovers its deformation, releases elastic potential energy, and pushes the screen plate 13 to move upward, further buffering the vibration and ensuring the stable operation of the screen plate 13.
[0028] See Figure 1 Two vibrating motors 17 are installed on one side of the outer wall of the screen mounting housing 12. One side of each vibrating motor 17 is fixedly connected to the screen mounting housing 12. The vibrating motors 17 generate high-frequency vibration to provide power for the screening process, causing the screen plate 13 to vibrate, thereby realizing the screening of coal gangue aggregate.
[0029] Working principle: When no external force is applied to the pressure rod 8, the assembly is stationary. The liftable support assembly maintains its current height, the positions of the support leg 2 and the toothed plate 3 are fixed, the spiral textured rotating disk 6 and the toothed plate 3 are in a stationary meshing state, the gear 7 is also stationary, and the contact position between the traction rod 9 and the gear 7 is stable. When a downward pressing force is applied to the pressure rod 8, the pressure rod 8 rotates around the rotating connection point in the middle of the gear 7. Since one side of the top of the pressure rod 8 is rotatably connected to the traction rod 9, the rotation of the pressure rod 8 will drive the traction rod 9 to rotate. As the traction rod 9 rotates, the toothed block and the gear 7 move relative to each other. The toothed block pushes the gear 7 to rotate, thereby driving the spiral textured rotating disk 6 and the toothed plate 3 to mesh and rotate, causing the toothed plate 3 to slide on the inner wall of the fixed housing 4, thereby driving the support leg 2 to move and realize the adjustment of the support leg 2.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
