Description

Technical Field

[0001] The present invention relates to the field of mining, and more particularly to a mining crusher. Background Art

[0002] In mining operations, ore crushing is an indispensable part. However, traditional mining crushers often produce a lot of slag and dust during operation, especially when drilling holes on irregular walls. These problems are particularly prominent. The slag scattering not only wastes resources, but also may pollute the surrounding environment; while the flying dust seriously affects the health of operators and also increases safety hazards.

[0003] In order to solve the above problems, many improvements have been made to the design and use of existing mining crushers. For example, some crushers have added water spraying and dust reduction devices during the crushing process, trying to reduce dust generation by wetting the ore. However, although this method alleviates the dust problem to a certain extent, the slag after water spraying is more difficult to collect and handle, which increases the difficulty of subsequent work.

[0004] In addition, some crushers are equipped with dust collectors at the outlet of the crushing chamber, trying to separate dust from the air by filtering. However, this type of dust collector can only handle suspended particles in the air, but is powerless against slag that has already attached to the wall or scattered on the ground.

[0005] In view of the deficiencies in the prior art, the present invention proposes a new type of mining crusher, aiming to solve the above technical problems. Summary of the invention

[0006] In order to overcome the deficiencies of the prior art, the present invention provides a mining crusher, which has the beneficial effect of being able to collect slag and block and isolate dust when drilling holes on irregular wall surfaces.

DETAILED DESCRIPTION

[0024] like Figures 1 to 5 and 10 to 11:

[0025] A mining crusher includes a base 101, a guide rod 104 and a reduction motor 102 are fixedly connected to the base 101, a top frame 105 is fixedly connected to the guide rod 104, a screw 103 is connected to the output shaft of the reduction motor 102 through a coupling, the screw 103 is rotatably connected to the top frame 105, a collar 108 is installed on the top frame 105, a plurality of mutually fitting arc baffles 201 are slidably connected around the collar 108, a plurality of dovetail blocks 109 are formed around the inner wall of the collar 108, a dovetail groove 202 is opened on the outer wall of each arc baffle 201, and each arc baffle 201 is provided with a dovetail groove 202. 01 are all slidably connected to the corresponding dovetail block 109 through the dovetail groove 202, the collar 108 and the arc baffle 201 are locked and fixed by screws, the lower end of each arc baffle 201 is fixedly connected to a grip rod, and a bracket 401 is arranged at the lower end of multiple arc baffles 201, and the bottom surface of the bracket 401 is symmetrically fixed with two brackets 402, one bracket 402 is slidably connected to the guide rod 104, and the other bracket 402 is threadedly connected to the screw 103, and a driving motor 403 is fixedly connected to the bracket 401, and a drill bit 404 is fixedly connected to the output shaft of the driving motor 403;

[0026] When the top surface is broken and drilled, the slag produced in the drilling process will fall downwards, and the dust produced will diffuse outwards, causing pollution and influence on the surrounding environment and people's sight. Therefore, when breaking and drilling, in order to overcome the above problems, when the device is used, the device is moved to the position to be broken and drilled, and the vertical positions of the plurality of arc-shaped baffles 201 are adjusted so that the plurality of arc-shaped baffles 201 are surrounded and fitted around the position to be drilled in the circumferential direction, and then the reduction motor 102 is controlled to start and drive the screw 103 to rotate, and the screw 103 drives the bracket 401 to move upward through the bracket 402, and the bracket 401 drives the drive motor 403 and the drill bit 404 to move upward, and the drive motor 403 starts The drill bit 404 is driven to rotate at high speed to contact the wall surface for drilling. The multiple arc baffles 201 surround and fit each other to block the dust generated during the drilling process, preventing the dust from spreading wantonly and entering the eyes and respiratory tract of the workers. At the same time, the bracket 401 enters the multiple arc baffles 201. The bracket 401 and the multiple arc baffles 201 form a space for receiving slag, and the slag and dust generated by the drilling are received and collected to prevent the dust from falling directly downward and polluting the environment and air. After the drilling is completed, the screw 103 is controlled to rotate in the opposite direction to drive the drill bit 404 to be retracted, and the device is removed to centrally process the slag collected in the bracket 401 and the multiple arc baffles 201.

[0027] Furthermore, the vertical position of each arc baffle 201 relative to the collar 108 can be adjusted individually, so that multiple arc baffles 201 can be pressed against an irregular wall surface to collect slag and block and isolate dust when drilling holes in the irregular wall surface.

[0028] Further:

[0029] The diameter of the bracket 401 is equal to the diameter of the inner wall of the circle formed by the plurality of arc-shaped baffles 201;

[0030] The bracket 401 entering into the plurality of arc-shaped baffles 201 can keep in contact with the inner wall of each arc-shaped baffle 201 , thereby preventing slag from falling from the gap between the bracket 401 and the arc-shaped baffle 201 .

[0031] like Figures 6 to 8 As shown:

[0032] It also includes a plurality of fan-shaped plates 204, each of which is formed with a dovetail block II 208 on the inner side, and the plurality of fan-shaped plates 204 are slidably connected to the dovetail grooves 202 on the plurality of arc-shaped baffles 201 through the dovetail blocks II 208, and a cone tip 205 is fixed to the bottom surface of each fan-shaped plate 204;

[0033] When the arc baffle 201 is against the vicinity of the position to be punched, the cone tip 205 is held by hand to push the fan plate 204 upward, so that the fan plate 204 fits around the position to be punched, and then supports the vicinity of the position to be punched. The arc baffle 201 also increases the contact area between the arc baffle 201 and the wall surface, thereby providing support in a larger range, avoiding collapse around the punching position due to vibration, or preventing gravel from falling off the wall surface and injuring workers due to vibration, thereby protecting the safety of workers.

[0034] Furthermore, the position of each sector plate 204 relative to the arc-shaped baffle 201 can be adjusted individually, so that a plurality of sector plates 204 can also be attached to an uneven wall surface to support and stabilize the uneven wall surface;

[0035] Furthermore, in the initial state, the fan-shaped plate 204 is located at the lower end of the arc-shaped baffle plate 201 and will not block the upper end of the arc-shaped baffle plate 201. This is to expose the upper ends of multiple arc-shaped baffle plates 201, so as to facilitate accurate finding and alignment of the positions to be drilled, and then adjust the multiple fan-shaped plates 204 to move upward and fit against the wall surface for further support and stability.

[0036] like Figure 1 As shown:

[0037] The plurality of sector plates 204 on the same plane form a circular ring;

[0038] The plurality of sector plates 204 form a closed loop in the circumferential direction, which can support and stabilize the wall surface more comprehensively in the circumferential direction around the punching position, and at the same time can provide safer protection for the workers under the sector plates 204.

[0039] like Figure 7 As shown:

[0040] The upper end of each arc-shaped baffle 201 is provided with an insertion hole 203, and the bottom surface of each fan-shaped plate 204 is provided with a card that can be inserted into the insertion hole 203;

[0041] The cone tip 205 is held by hand and the sector plate 204 is pushed upward. When the clamp is aligned with the insertion hole 203, the clamp will be automatically inserted into the insertion hole 203 to lock the position of the sector plate 204.

[0042] like Figures 8 to 9 As shown:

[0043] The clamping member includes a vertical plate 207 fixed to the bottom surface of the fan-shaped plate 204, a plug rod 301 is slidably connected to the vertical plate 207, a compression spring 305 is sleeved on the plug rod 301, and two ends of the compression spring 305 are respectively fixed to the plug rod 301 and the vertical plate 207;

[0044] When the fan-shaped plate 204 moves upward, the inner side of the insertion rod 301 slides upward against the surface of the dovetail groove 202, and the compression spring 305 is in a compressed state. When the insertion rod 301 is aligned with the insertion hole 203, the elastic force of the compression spring 305 pushes the insertion rod 301 to automatically insert into the insertion hole 203, thereby locking the position of the fan-shaped plate 204.

[0045] like Figures 7 to 9 As shown:

[0046] The clamping member further comprises a bevel block 302 fixedly connected to the outer end of the insertion rod 301, and a handle 304 slidably connected to the cone tip 205, and a pressing rod 303 fixedly connected to the handle 304 and attached to the bevel of the bevel block 302;

[0047] When it is necessary to adjust the fan-shaped plate 204 to slide downward, the finger hooks the handle 304 and moves downward, the handle 304 drives the pressure rod 303 to move downward, the pressure rod 303 presses the inclined surface block 302 downward, so that the inclined surface block 302 slides outward relative to the pressure rod 303, the inclined surface block 302 drives the insertion rod 301 to slide outward and be pulled out of the insertion hole 203, and then the handle 304 continues to be pressed downward, the handle 304 fits on the cone tip 205 and drives the cone tip 205 and the fan-shaped plate 204 to slide downward, so that the position of the fan-shaped plate 204 is unlocked.

[0048] like Figure 6 As shown:

[0049] Each of the sector plates 204 is fixedly connected with a plurality of cone tips 205;

[0050] The multiple cone tips 205 enable the multiple sector plates 204 to be better embedded in the gaps of the wall, so that the sector plates 204 fit better with the wall.

[0051] like Figure 3 As shown:

[0052] Ear plates 107 are fixedly connected to both sides of the collar 108, two electric push rods 106 are fixedly connected to the top frame 105, and the telescopic ends of the two electric push rods 106 are respectively fixedly connected to the two ear plates 107;

[0053] The two electric push rods 106 are started to drive the collar 108 to move up and down, and the collar 108 drives the multiple arc-shaped baffles 201 to move up and down, so that the multiple arc-shaped baffles 201 are further accurately fitted on the wall surface around the hole to be punched.

[0054] like Figure 3 As shown:

[0055] The four corners of the base 101 are provided with round holes for installing universal wheels or for passing bolts to fix the base 101 on the robot arm.
