Description

Technical Field

[0001] This utility model belongs to the technical field of gangue crushing devices, and more specifically, it relates to a crushing and processing device for solid waste in mining. Background Technology

[0002] Solid waste crushing equipment is a device used to mechanically crush solid waste materials. It has been widely used in waste treatment, resource recycling, construction and demolition projects, medical waste treatment and other fields. It aims to process large pieces of waste into granules and powders to facilitate subsequent transportation and resource recovery, so as to solve waste management problems and environmental challenges. Especially in the mining industry, crushed gangue is used for filling goaf areas and slowing down the secondary subsidence of the overlying strata after coal mining.

[0003] Based on the above, the following problems were found: Although the existing roller crushing structure is powerful enough to crush a large amount of solid waste, the volume of the crushed waste is usually fixed, while different solid wastes require different crushing sizes, which leads to situations where the crushing is overdone at times and insufficiently fine at other times. At the same time, there will be gaps during crushing, which will cause some waste that does not meet the crushing standards to be discharged together, resulting in crushing results that do not meet the standards.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a mining solid waste crushing and processing device in order to achieve a more practical value. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a mining solid waste crushing and processing device, which solves the problem that the waste produced by existing roller crushing structures is usually of a fixed volume, resulting in over-crushing at times and insufficient fineness at other times.

[0006] This utility model provides a crushing and processing device for solid waste in mining, which is achieved by the following specific technical means:

[0007] A mining solid waste crushing and processing device includes an outer shell. Support legs are fixed at the four corners of the bottom of the outer shell. A first servo motor is fixed on one side of the outer wall of the outer shell. The power output end of the first servo motor passes through the outer wall of the outer shell and is fixed to a first crushing roller. Slide grooves are opened through both sides of the outer wall of the outer shell. A slider is slidably connected inside each of the two slide grooves. A second servo motor is fixed on one side of one of the sliders. The power output end of the second servo motor passes through the slider and is fixed to a second crushing roller. A connecting rod is fixed on one side of both sliders. A distance adjustment mechanism is provided on the side of the outer shell near the connecting rod.

[0008] Furthermore, the distance adjustment mechanism includes a threaded rod, which is threadedly connected to the middle of the connecting rod, and one end of the threaded rod is rotatably connected to the outer wall of the outer casing, while the other end of the threaded rod is fixed with a knob.

[0009] Furthermore, a second baffle plate is fixed on each of the two sliders on opposite sides, and the length of the second baffle plate is greater than the length of the chute.

[0010] Furthermore, a first filter screen is fixed to the bottom of the inner wall of the outer shell. The first filter screen is inclined. A rectangular through hole is opened above the end of the outer shell near the first filter screen. A second filter screen is slidably connected inside the rectangular through hole. A first connecting block is fixed to one end of the second filter screen. A second connecting block is fixed to the outer wall of the outer shell near the middle of the rectangular through hole. A limit bolt is threaded through the top of the second connecting block.

[0011] Furthermore, a side outlet is provided through the outer shell near the bottom of the first filter screen, and the bottom of the side outlet is at the same level as the top of the second filter screen.

[0012] Furthermore, guide rails are fixed at both ends of the outer wall of the outer shell near the side outlet, and a first baffle plate is slidably connected inside the two guide rails. A handle is fixed in the middle of one side of the first baffle plate.

[0013] Furthermore, guide plates are fixed at both ends of the top of the inner wall of the outer shell. The two guide plates are arranged in a V-shape, and the bottom of one of the guide plates is located on the same vertical plane as the middle of the first crushing roller.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, the distance between the first crushing roller and the second crushing roller is adjusted according to the size of the solid waste after crushing. Rotating the knob drives the threaded rod to rotate, thereby adjusting the position of the connecting rod, so that the slider slides inside the groove, thereby changing the position of the second servo motor and the second crushing roller, thus changing the distance between the first crushing roller and the second crushing roller, thereby achieving the effect of adjusting the size of the crushed waste as needed.

[0016] 2. In this utility model, small-volume waste materials after crushing move directly downwards through the first and second filter screens. The second and first filter screens work together to screen the waste materials, leaving some large-volume solids on top of the second filter screen. When too many large-volume solid waste materials accumulate on top of the second filter screen, the handle is lifted upwards to move the first baffle plate along the guide rail, allowing the large-volume solid waste materials on top to be removed from the side discharge port for secondary crushing. This achieves the effect of screening the crushed waste materials according to the corresponding standards, thereby improving the screening qualification rate. Attached Figure Description

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a mining solid waste crushing and processing device, including an outer shell 1. Support legs 2 are fixed at the four corners of the bottom of the outer shell 1. A first servo motor 11 is fixed on one side of the outer wall of the outer shell 1. The power output end of the first servo motor 11 passes through the outer wall of the outer shell 1 and is fixed to a first crushing roller 12. Slide grooves 7 are opened through both sides of the outer wall of the outer shell 1. Sliding blocks 8 are slidably connected inside the two slide grooves 7. A second servo motor 13 is fixed on one side of one of the sliding blocks 8. The power output end of the second servo motor 13 passes through the sliding block 8 and is fixed to a second crushing roller 14. A connecting rod 10 is fixed on one side of the two sliding blocks 8. A distance adjustment mechanism is provided on the side of the outer shell 1 near the connecting rod 10. The first servo motor 11 drives the first crushing roller 12 to rotate, and the second servo motor 13 drives the second crushing roller 14 to rotate in the opposite direction. The first crushing roller 12 and the second crushing roller 14 cooperate to crush the solids thrown into the outer shell 1.

[0028] The distance adjustment mechanism includes a threaded rod 15, which is threadedly connected to the middle of the connecting rod 10. One end of the threaded rod 15 is rotatably connected to the outer wall of the outer casing 1, and the other end of the threaded rod 15 is fixed with a knob 16. By rotating the knob 16, the threaded rod 15 is rotated, thereby adjusting the position of the connecting rod 10, so that the slider 8 slides inside the slide groove 7, thereby changing the position of the second servo motor 13 and the second crushing roller 14, and thus changing the distance between the first crushing roller 12 and the second crushing roller 14.

[0029] Each of the two sliders 8 has a second baffle plate 9 fixed on one side opposite to the other. The length of the second baffle plate 9 is greater than the length of the slide groove 7. The second baffle plate 9 blocks the slide groove 7 to prevent solid waste inside the outer shell 1 from entering the slide groove 7 and affecting the movement of the sliders 8.

[0030] The outer casing 1 has a first filter screen 17 fixed to the bottom of its inner wall. The first filter screen 17 is inclined. A rectangular through hole 21 is opened above the upper part of the outer casing 1 near the first filter screen 17. A second filter screen 18 is slidably connected inside the rectangular through hole 21. A first connecting block 181 is fixed to one end of the second filter screen 18. A second connecting block 19 is fixed to the outer wall of the outer casing 1 near the middle of the rectangular through hole 21. A limit bolt 20 is threadedly connected to the top of the second connecting block 19. After the distance between the first crushing roller 12 and the second crushing roller 14 is adjusted, the position of the second filter screen 18 is then adjusted so that the size of the overlap between the meshes of the second filter screen 18 and the first filter screen 17 matches the distance between the first crushing roller 12 and the second crushing roller 14. Then, the limit bolt 20 is rotated to fix the first connecting block 181 and the second connecting block 19, thereby limiting the position of the second filter screen 18.

[0031] The outer shell 1 has a side outlet 4 through it on the side near the bottom of the first filter screen 17. The bottom of the side outlet 4 is at the same level as the top of the second filter screen 18. The second filter screen 18 and the first filter screen 17 work together to screen the solids, and some of the larger solids remain on the top of the second filter screen 18.

[0032] Among them, the outer wall of the outer shell 1 is fixed with guide rails 5 at both ends near the side discharge port 4. The two guide rails 5 are slidably connected with the first baffle plate 6. A handle 61 is fixed in the middle of one side of the first baffle plate 6. When too much large solid waste accumulates on the top of the second filter screen 18, the handle 61 is lifted upward to move the first baffle plate 6 along the guide rail 5, so that the large solid waste on the top can be removed from the side discharge port 4.

[0033] The outer shell 1 has guide plates 3 fixed at both ends of the top of the inner wall. The two guide plates 3 are arranged in a V-shape, and the bottom of one of the guide plates 3 is located on the same vertical plane as the middle of the first crushing roller 12. The solid waste poured into the top of the outer shell 1 is guided by the guide plates 3 to the middle of the first crushing roller 12 and the second crushing roller 14.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, the distance between the first crushing roller 12 and the second crushing roller 14 is first adjusted according to the size of the solid waste to be crushed. Rotating the knob 16 drives the threaded rod 15 to rotate, thereby adjusting the position of the connecting rod 10, causing the slider 8 to slide inside the groove 7. This changes the position of the second servo motor 13 and the second crushing roller 14, thus altering the distance between the first crushing roller 12 and the second crushing roller 14. Then, the position of the second filter screen 18 is adjusted so that the overlap between the meshes of the second filter screen 18 and the first filter screen 17 matches the distance between the first crushing roller 12 and the second crushing roller 14. Next, the limiting bolt 20 is rotated to fix the first connecting block 181 and the second connecting block 19, limiting the position of the second filter screen 18. Finally, the solid waste is poured into the outer casing. At the top of body 1, solid waste poured into the top of the outer shell 1 is guided by the guide plate 3 to the middle of the first crushing roller 12 and the second crushing roller 14. The first servo motor 11 drives the first crushing roller 12 to rotate, and the second servo motor 13 drives the second crushing roller 14 to rotate in the opposite direction. The first crushing roller 12 and the second crushing roller 14 cooperate to crush the solid inside. After crushing, the small waste directly moves down from the first filter screen 17 and the second filter screen 18. It is screened by the cooperation of the second filter screen 18 and the first filter screen 17. Some of the large solids remain on the top of the second filter screen 18. When too much large solid waste accumulates on the top of the second filter screen 18, the handle 61 is lifted upward to move the first baffle plate 6 up along the guide rail 5, so that the large solid waste on the top can be removed from the side outlet 4.
