Description

Technical Field

[0001] This utility model relates to the field of stone crushing equipment technology, specifically to a stone crushing machine for mining. Background Technology

[0002] Mines include coal mines, metal mines, non-metal mines, building material mines, and chemical mines, etc. During the mining process, many production processes and procedures, such as drilling, blasting, ore extraction, and rock loading, require the use of stone crushers to completely break down the rocks in the mine to meet the needs of production and processing. Stone crushers, also known as crushers, are crushing machines used in the processing of metal and non-metal ores. They are crushing machines that can break down the mined raw ore into small particles through compression and bending. When crushing ores, a type of mining stone crushing machinery is required.

[0003] In existing crushing equipment, the ore is typically screened before crushing. However, this screening process also generates a significant amount of dust and other impurities. Existing crushing equipment can only effectively filter the dust and other impurities generated during crushing, not those generated during screening, leading to continued environmental pollution. Furthermore, existing crushing equipment cannot effectively disassemble and replace the filter plates. After prolonged use, the filter plates inevitably become clogged. If these are not replaced, they will fail to effectively absorb and filter dust and other impurities, reducing the overall practicality of the equipment.

[0004] Compared with Chinese Patent Publication No. CN221656806U, this utility model discloses a mining crushing device with good dust prevention effect. The device includes a crusher and a feed hopper. The feed hopper is fixedly installed on the top of the crusher, and a dust removal component is also fixedly installed on the top of the crusher. The dust removal component includes a limiting pin, a water tank, a water tank cover, and a fan. The limiting pin is fixedly installed on the top of the crusher, and the water tank is slidably installed on the top of the crusher. A water tank cover is slidably embedded in the top of the water tank, and a fan is fixedly installed on the top of the crusher. The dust removal component also includes an air pipe, a water injection box, a drain pipe, and a valve. Compared with the prior art, the beneficial effect of this utility model is that the dust generated during ore crushing is easily absorbed and treated through the dust removal component, avoiding the possibility of workers developing illnesses due to dust, and improving the safety and cleanliness of the production environment.

[0005] The above solution can effectively filter out dust and other impurities generated during the crushing process of crushed stone. However, the above solution still cannot effectively filter out impurities generated during the screening process of ore. Furthermore, the above solution cannot effectively disassemble and replace the filter plate, thus failing to solve the problems mentioned in the background art.

[0006] Therefore, those skilled in the art have provided a crushing machine for mining to solve the problems mentioned in the background art. Utility Model Content

[0028] 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.

[0029] Please see Figure 1 - Figure 6 As shown, this embodiment provides a crushing machine for mining, including a conveying device 1, and further comprising:

[0030] The crushing device 2 is located above the conveying device 1. The upper surface of the crushing device 2 is connected to the first feed hopper 3, and the rear end surface of the crushing device 2 is fixedly connected to the conveying channel 5. The upper surface of the conveying channel 5 is connected to the second feed hopper 4.

[0031] The screening component is located above the second feed hopper 4;

[0032] A filter assembly is disposed on the upper surface of the pulverizing device 2;

[0033] An adjustment component is provided on the front surface of the first feed hopper 3;

[0034] The mounting components are symmetrically arranged on both sides of the outer wall of the filter assembly.

[0035] The working principle described above is as follows: When ore needs to be crushed, simply place the ore inside the screening assembly. The screening assembly then begins operation, effectively screening the ore. Smaller pieces will fall naturally into the second feed hopper 4, and then be conveyed to the conveying channel 5, finally falling onto the conveying equipment 1. Larger pieces, however, will be shaken off the incline of the screening assembly into the first feed hopper 3, and then conveyed to the crushing equipment 2 for crushing. During the screening and crushing process... A large amount of dust and other impurities will be generated. At this time, the filter component starts to operate and can effectively adsorb and filter dust and other impurities, thereby effectively protecting the environment. By adjusting the settings of the component, the height position of the internal parts of the filter component can be effectively adjusted. When it is necessary to disassemble and replace the internal parts of the filter component, it is only necessary to install the component to easily disassemble the internal parts of the filter component, so as to facilitate the replacement of the internal parts of the filter component by the staff, effectively improving the filtration effect of the filter component, saving time and effort.

[0036] To effectively screen the ore, the screening assembly includes a screening frame 6 located above the second feed hopper 4. Side plates 7 are fixedly connected to both sides of the outer wall of the screening frame 6. Connecting rods 24 are symmetrically arranged at the bottom of each side plate 7. Abutment discs 23 are fixedly connected to the bottom ends of the connecting rods 24. Multiple support plates 8 are fixedly connected to the outside of the conveying channel 5. A rotating rod 21 is rotatably connected between every two support plates 8. A limit disc 10 is fixedly connected to one end of each rotating rod 21. A first motor 9 is fixedly connected to the outside of one of the support plates 8. The output shaft of the first motor 9 is fixedly connected to the other end of one of the rotating rods 21 via a coupling. The two rotating rods 21 are connected by a synchronous belt 11 and a pulley. Cams 22 are symmetrically arranged on the outside of each of the two rotating rods 21. Guide grooves for the movement of the cams 22 are opened at the bottom of the multiple abutment discs 23. When screening of the ore is required... Simply place the ore inside the screening frame 6. At this time, the first motor 9 starts running, driving one of the rotating rods 21 to rotate synchronously. Since the two rotating rods 21 are connected by a synchronous belt 11 and a pulley, they rotate synchronously, driving the cam 22 to rotate synchronously. During the rotation of the cam 22, it drives the contact plate 23 to move up and down synchronously. The contact plate 23 then drives the connecting rod 24 to move synchronously, and the connecting rod 24 then drives the side plate 7 and the screening frame 6 to move synchronously. At this time, the ore can be effectively screened by the up and down reciprocating movement of the screening frame 6. Smaller ore will fall directly into the second feed hopper 4, while larger ore will fall into the first feed hopper 3 due to the shaking of the screening frame 6 and the inclination inside the screening frame 6. This effectively screens the ore.

[0037] Considering the need to improve the stability of the screening frame 6 during its movement, both sides of the outer wall of the second feed hopper 4 are fixedly connected to a C-shaped plate 26 by support rods 25. Guide rods 27 are symmetrically arranged inside the C-shaped plate 26, with their ends fixedly connected to the top and bottom of the C-shaped plate 26, respectively. L-shaped plates 28 are fixedly connected to the bottom of both side plates 7, and guide grooves for the guide rods 27 are provided inside each L-shaped plate 28. Multiple guide rods 27 are fitted with a composite... The return springs 29 and multiple return springs 29 abut against the L-shaped plate 28 and the U-shaped plate 26. During the movement of the screening frame 6, the side plate 7 will move synchronously, and the side plate 7 will then drive the L-shaped plate 28 to move synchronously outside the guide rod 27. At this time, the stability of the screening frame 6 during the movement can be effectively improved by the cooperation between the L-shaped plate 28 and the guide rod 27. By setting the return springs 29, the screening frame 6 can be automatically reset, which effectively improves the screening effect of the screening frame 6.

[0038] To effectively adsorb and filter dust and other impurities, the filter assembly includes a filter box 12 and an air pump 17 respectively installed on the upper surface of the crushing device 2. An air suction hood 20 is installed above the screening frame 6. The air inlet of the air pump 17 is connected to a branch pipe 18, with the two inlets of the branch pipe 18 connected to the air suction hood 20 and the interior of the crushing device 2, respectively. The air outlet of the air pump 17 is connected to the interior of the filter box 12 via a pipe. Activated carbon filter plates 14 are symmetrically arranged inside the filter box 12. A top plate 15 is fixedly connected to the upper surface of each of the two activated carbon filter plates 14. A handle is fixedly connected to the upper surface of the top plate 15. Insert plates 16 are symmetrically arranged at the bottom of the top plate 15. Fixing frames 34 are symmetrically arranged on both sides of the outer wall of the filter box 12. Each fixing frame 34 has an opening on its upper surface for supplying air to the filter. The guide groove of the insert plate 16 is connected to the outside of the filter box 12 via an exhaust pipe 13. During the screening and crushing of ore, a large amount of dust and other impurities are generated. At this time, the suction pump 17 starts to run. The suction pump 17 draws the dust and other impurities into the interior of the filter box 12 through the branch pipe 18 and the suction hood 20. When the gas containing dust and other impurities enters the interior of the filter box 12, the activated carbon filter plate 14 can effectively filter and purify the gas containing dust and other impurities. The purified gas will be discharged through the exhaust pipe 13. At this time, the dust and other impurities generated during the screening and crushing of ore can be effectively adsorbed and filtered, thereby effectively protecting the environment and the health of the staff, and effectively improving the overall practicality of the device.

[0039] To effectively adjust the height of the suction hood 20, the adjustment assembly includes an adjustment plate 30 fixedly connected to the front surface of the first feed hopper 3. A second motor 19 is fixedly connected to the upper surface of the adjustment plate 30. The output shaft of the second motor 19 is fixedly connected to a threaded rod 31 via a coupling. The other end of the threaded rod 31 is rotatably connected to the inner bottom end of the adjustment plate 30. A threaded block 32 is threadedly connected to the outside of the threaded rod 31. A guide groove for the threaded block 32 to move is provided on the front surface of the adjustment plate 30. The front surface of the threaded block 32 is fixedly connected to... There is a connecting frame 33, the bottom of which is fixedly connected to the upper surface of the suction hood 20. When the height of the suction hood 20 needs to be adjusted, the second motor 19 starts to run. At this time, the second motor 19 will drive the threaded rod 31 to rotate synchronously, and the threaded block 32 will move synchronously outside the threaded rod 31, driving the connecting frame 33 to move synchronously. The connecting frame 33 then drives the suction hood 20 to move synchronously. At this time, the height of the suction hood 20 can be adjusted according to actual needs, further improving the overall practicality of the device.

[0040] In addition, to facilitate the fixed installation of the activated carbon filter plate 14, the installation assembly includes a fixed plate 35 fixedly connected to the outside of the fixed frame 34. A fixed rod 36 is provided inside the fixed plate 35, with a pull ring fixedly connected to one end of the fixed rod 36. An abutment plate 37 is fixedly connected to the outside of the fixed rod 36, and an abutment spring 38 is sleeved on the outside of the fixed rod 36, abutting between the abutment plate 37 and the fixed plate 35. Guide grooves for the movement of the fixed rod 36 are provided on the contact surfaces of the fixed plate 35 and the fixed frame 34. A guide groove for the movement of the fixed rod 36 is also provided inside the insert plate 16. When the activated carbon filter plate 14 needs to be fixedly installed, simply pull the pull ring, which will then move the fixed rod 36. The fixed rod 36 moves synchronously, and the contact plate 37 moves synchronously. During the movement of the contact plate 37, the contact spring 38 is compressed. At this time, the insert plate 16 is inserted into the inside of the fixed frame 34, and then the pull ring is released. At this time, the contact spring 38 returns to its original position, and the contact plate 37 and the fixed rod 36 move synchronously. When the fixed rod 36 is inserted into the guide groove inside the insert plate 16, the insert plate 16 and the fixed frame 34 can be fixed. At this time, the activated carbon filter plate 14 can be fixedly installed, and it is also convenient for the staff to disassemble and replace the activated carbon filter plate 14, which effectively improves the filtration effect and efficiency of the filter assembly.
