Description

Technical Field

[0001] The present application relates to the field of coal mine sorting, and in particular to a mobile support plate structure of a coal and gangue sorting device. Background Art

[0002] Currently, in the application of coal and gangue, gangue, as a by-product of coal mining, has a very wide application market. Gangue can not only be used to produce gangue bricks, cement and other building materials, but also can be used in road construction and backfilling projects. In addition, gangue can also be used to produce fertilizers, extract useful elements, etc., and has significant resource value. In order to effectively utilize these resources, the mobile pallet structure of the coal and gangue sorting device plays a vital role in the gangue processing process, which can improve the sorting efficiency and ensure product quality.

[0003] For example, the mobile support plate structure of a coal and gangue sorting assembly device in patent No. 202223427731.3, including a receiving plate, a support pipe, a position and shape holding bin, a connecting plate and a shell, still has the following shortcomings in actual use:

[0004] The above-mentioned patent discloses a movable support plate structure for a coal and gangue sorting device. In actual use, the receiving plate on the top has too little support surface. When the receiving plate needs to receive larger materials, the receiving plate cannot bear the weight of the materials due to the small support contact surface at the bottom of the receiving plate, causing damage to the middle section of the receiving plate. At the same time, since there is no buffer when the receiving plate receives the materials, it is very easy for the connection between the push rod and the receiving plate to break. When the material hits the side wall of the receiving plate, the fixing method of the receiving plate is very unstable, causing the receiving plate to twist and bend after the impact.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] An embodiment of the present application discloses a movable support plate structure for a coal and gangue sorting device.

[0035] The observation view of this device (front, back, left, right) is as follows Figure 1 For reference benchmark.

[0036] Example 1

[0037] Reference Figure 1 , 2 A mobile support plate structure for a coal and gangue sorting device includes a fixed block 1, an auxiliary cavity is opened inside the fixed block 1, a motor 101 is fixedly installed in the auxiliary cavity opened inside the fixed block 1, a gear is fixedly connected to the outer wall of the output shaft of the motor 101, the motor 101 is meshed with the tooth groove inside the inner gear ring 102 through the gear, the inner gear ring 102 is rotatably connected to the auxiliary cavity inside the fixed block 1, the teeth of the clamping block 103 are meshed in the tooth groove of the inner gear ring 102, the clamping block 103 is slidably connected to the auxiliary cavity inside the fixed block 1, one side of the telescopic rod 104 is fixedly connected to the bottom of the clamping block 103 by welding, and the telescopic rod 104 is slidably connected to the auxiliary cavity inside the fixed block 1.

[0038] The auxiliary cavity opened inside the fixed block 1 is the prior art, and the shape of the cavity will not be described in detail here. The motor 101 is the prior art and will not be described in detail here. The mounting end of the motor 101 is fixed in the auxiliary cavity of the fixed block 1, and the output end of the motor 101 is fixedly connected with a gear, which is meshed with the inner gear ring 102. The infrared sensor is connected to the control circuit of the motor 101, and the receiving pin of the infrared sensor is connected to the input signal port of the motor 101. The output signal port of the control circuit of the motor 101 is connected to the drive circuit of the motor 101.

[0039] By setting, through the infrared sensor set on the upper surface of the receiving block 207, when the infrared sensor detects an object above the receiving block 207, it starts to output and transmits a signal to the single-chip microcomputer through the wire, and the single-chip microcomputer drives and controls the motor 101, and the motor 101 is powered on and started, and the output shaft of the motor 101 starts to rotate left. When the output shaft of the motor 101 starts to rotate left, the output shaft of the motor 101 drives the gear to rotate and then drives the inner gear ring 102 to rotate, and the inner gear ring 102 rotates left in the auxiliary cavity. When the inner gear ring 102 starts to rotate left, the block 103 stuck in the tooth groove of the inner gear ring 102 starts to slide toward the outside of the auxiliary cavity opened in the fixed block 1 with the fixedly connected telescopic rod 104, and when the telescopic rod 104 slides outward, the receiving block 207 fixedly connected to the upper end of the telescopic rod 104 moves with the telescopic rod 104 to receive the material.

[0040] Reference Figure 1 , 2 , 3, 4, the sliding clamping mechanism 2 includes a square groove 201 with a path array opened on the upper surface of the fixed block 1, two sides of the connecting column 202 are fixedly connected to the middle of the two sides of the square groove 201, the inner rotation of the roller 203 is connected to the middle of the outer wall of the connecting column 202, the bottom of the extension block 204 is fixedly connected to the middle of the upper section of the fixed block 1, the trapezoidal groove 205 runs through the middle of the extension block 204, the trapezoidal block 206 is slidably connected to the upper end of the trapezoidal groove 205 and the upper end of the roller 203, the trapezoidal block 206 is simultaneously clamped in the trapezoidal groove 205, and the bottom of the receiving block 207 is fixedly connected to the top of the trapezoidal block 206 and the top of the telescopic rod 104.

[0041] By setting, when the telescopic rod 104 slides outward, the receiving block 207 slides outward with the telescopic rod 104, and through the outward sliding of the receiving block 207, the trapezoidal block 206 begins to slide outward inside the trapezoidal groove 205, and through the sliding of the trapezoidal block 206, the roller 203 begins to rotate on the outer wall of the connecting column 202.

[0042] Reference Figure 1 , 25. The buffer mechanism 3 comprises a T-slot 301 which is not penetrated through the upper surface of the receiving block 207, a long groove 302 is formed in the middle of the T-slot 301 formed in the receiving block 207, the bottom of the buffer plate 303 is fixedly connected to the surface of the long groove 302 by an adhesive, the fixing columns 304 symmetrically penetrate the two sides of the buffer plate 303 and are fixedly connected to the surface of the long groove 302, the T-slide block 305 is vertically movably connected to the inside of the T-slot 301, the lower end of the connecting block 306 is fixedly connected to the upper end of the T-slide block 305 by welding, the connecting block 306 is slidably connected to the inside of the long groove 302, the round groove 307 is symmetrically not penetrated through the lower surface of the connecting block 306, and the two ends of the spring 308 are fixedly connected to the inner wall of the round groove 307 and the upper end of the fixing column 304 by welding.

[0043] By setting, when the receiving block 207 slides outward to receive the material, the material will fall on the upper surface of the receiving block 306. When the material falls on the surface of the receiving block 306, the weight of the material itself will give the receiving block 306 a downward pressure, causing the receiving block 306 to move downward. Through the downward movement of the receiving block 306, the T-shaped slider 305 begins to slide downward inside the T-shaped slot 301, and the spring 308 begins to shrink due to the squeezing of the receiving block 306 and the fixed column 304. When the material is too heavy, the receiving block 306 will slide downward quickly, and the bottom of the receiving block 306 will directly contact the upper surface of the buffer plate 303, and the buffer plate 303 itself will be used for shock absorption.

[0044] When the material rolls from above the receiving block 306 to the material receiving area, the spring 308 begins to push the receiving block 306 to slide upward in the long groove 302 through its own elasticity. When the receiving block 306 slides upward in the long groove 302, the T-shaped slider 305 fixedly connected to the bottom of the receiving block 306 begins to slide upward in the T-shaped groove 301. When the spring 308 returns to its initial state, the receiving block 306 stops moving upward.

[0045] The implementation principle of the mobile support structure of a coal and gangue sorting device in an embodiment of the present application is as follows: the material is detected by an infrared sensor, and the signal of the infrared sensor is transmitted to the single-chip microcomputer, which controls the start motor 101, and the telescopic rod 104 is caused to slide outward through the inner gear ring 102, and the receiving block 207 fixedly connected above the telescopic rod 104 begins to slide outward, the trapezoidal block 206 begins to slide in the trapezoidal groove 205, and the roller 203 begins to rotate on the outer wall of the connecting column 202. When the receiving block 306 receives the material, the spring 308 begins to shrink in the circular groove 307 due to the weight of the material itself, and at the same time, the sensor starts the motor 101 to make the telescopic rod 104 slide inward, and slide inward through the telescopic rod 104. When the material slides out of the upper surface of the receiving block 306, the spring 308 begins to extend inside the circular groove 307, so that the receiving block 306 returns to its initial state.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
