Description

Technical Field

[0001] The invention belongs to the technical field of crushing devices, and in particular relates to a mountain-breaking and wall-breaking machine. Background Art

[0002] Mining is the process of extracting metal ores, coal, oil and other mineral resources from the surface or underground and processing them into industrial raw materials. Because most minerals are closely combined with the surrounding rocks in nature, they need to be exposed by breaking the walls. At the same time, open-pit mining requires stripping off the topsoil and rock layers, and underground mining requires excavating tunnels through the rock layers, both of which require wall breaking operations.

[0003] However, in mining operations, when faced with hard rock mountains, traditional crushing devices such as impact drills and electric hammers can achieve a certain crushing effect. However, when faced with large-scale mountain excavation projects, there are often problems such as low power transmission efficiency and poor crushing uniformity, which makes the operation process time-consuming and labor-intensive, seriously affecting mining efficiency.

[0004] To this end, we provide a mountain-breaking machine to solve the above problems. Summary of the Invention

[0031] Example 1 See also Figures 1 to 6The present invention is a mountain-breaking wall-breaking machine, comprising a power motor 100; a reduction chamber 200 is fixedly connected to the front end of the power motor 100, a driving chamber 300 is fixedly connected to the front end of the driving chamber 300, an end cover 400 is fixedly connected to the front end of the end cover 400, a wall-breaking knife 600 is installed at the front end of the end cover 400, and a flushing assembly 700 is provided on the top of the end cover 400. The power motor 100, the reduction chamber 200, the driving chamber 300 and the end cover 400 are connected in sequence to form a complete power transmission and working structure, so that the power of the power motor 100 is stably transmitted to the wall-breaking knife 600, laying a power foundation for the wall-breaking operation; the flushing assembly 700 provided on the top of the end cover 400 can cool the wall-breaking knife 600 during the wall-breaking process and reduce dust at the same time; The center of the reduction chamber 200 is rotatably connected to a drive shaft 202, one end of the drive shaft 202 facing the power motor 100 is fixedly connected to a gear seat 203, and the other end of the drive shaft 202 is fixedly connected to a driving bevel gear 307. The front end of the reduction chamber 200 is fixedly connected to a lubrication chamber 301, and the interior of the lubrication chamber 301 is rotatably connected to a horizontal rotating shaft 308 and a first fixed shaft 311 symmetrically distributed on both sides. The outside of the rotating shaft 308 is fixedly connected to two symmetrically distributed driving gears 310 and a driven bevel gear 309 meshing with the driving bevel gear 307. The outsides of the two first fixed shafts 311 are rotatably connected to driven gears 312 meshing with the corresponding driving gears 310. The two driven gears A second fixed shaft 314 is fixedly connected to the edge of each side opposite to 312. Two parallel guide rods 302 are fixedly connected between the deceleration chamber 200 and the end cover 400. The outside of the two guide rods 302 is slidably connected to a sliding seat 303. The inside of the sliding seat 303 is fixedly connected to a connecting rod 304. The outside of the connecting rod 304 is fixedly connected to a fixed block 313. A connecting rod 315 is rotatably connected between the fixed block 313 and the two second fixed shafts 314. The rotation of the two driven gears 312 can drive one end of the connecting rod 315 to rotate around the circumference, so that the other end of the connecting rod 315 can drive the connecting rod 304 to reciprocate at a high frequency, thereby achieving efficient crushing of the mine wall. The end cover 400 is fixedly connected to the inside of the shaft sleeve 401, and the inside of the shaft sleeve 401 is movably connected to the movable rod 402, and the connecting rod 304 is fixedly connected to one end of the movable rod 402 located inside the drive chamber 300, and the wall-breaking knife 600 is detachably fixed to the other end of the movable rod 402. The wall-breaking knife 600 is detachably connected, which is convenient for replacement when worn or damaged, thereby reducing equipment maintenance costs and extending equipment service life.

[0032] Specifically, the interior of the reduction chamber 200 is fixedly connected to an inner gear ring 201, the output end of the power motor 100 is fixedly connected to a central gear 205, and the interior of the gear seat 203 is rotatably connected to two symmetrically distributed planetary gears 204, and the planetary gears 204 are meshed with the central gear 205 and the inner gear ring 201. The transmission structure of the planetary gear 204 can achieve a large transmission ratio, while ensuring power transmission, effectively reducing the speed and increasing the torque, meeting the high torque demand of the mountain breaker operation and improving the working performance of the equipment; The wall-breaking knife 600 includes a knife body 601 fixedly connected to the movable rod 402 at one end outside the end cover 400, and a plurality of crushing teeth 605 are fixedly connected to the bottom of the knife body 601. A placement groove 602 is provided at the top of the knife body 601, and a water outlet 603 connected to the placement groove 602 is provided at the free end of the knife body 601. The crushing teeth 605 enhance the material crushing ability of the knife body 601 and improve the wall-breaking effect; the placement groove 602 and the water outlet 603 provide installation space and liquid outflow channel for the liquid guide tube 702 of the flushing component 700.

[0033] Furthermore, the crushing teeth 605 are inverted teeth, and the multiple crushing teeth 605 are arranged in three staggered rows. The inverted teeth 605 increase the friction and crushing force with the material, and the three staggered rows expand the crushing range, improve the crushing uniformity and efficiency, so that the mountain breaking machine can better handle various hard materials. The lubrication chamber 301 is filled with lubricating oil. A refueling port 301a and an oil drain port 301c are respectively provided at the top and bottom of the lubrication chamber 301. A sealing plug 301b is threadedly sleeved on the interior of the refueling port 301a, and a sealing cap 301d is threadedly sleeved on the bottom of the oil drain port 301c. The lubricating oil lubricates the components inside the lubrication chamber 301, reducing friction and wear and extending the service life of the components. The refueling port 301a and the oil drain port 301c facilitate the addition and replacement of lubricating oil, maintain good lubrication effect, and ensure stable operation of the equipment. The power motor 100 is an explosion-proof motor. In dangerous environments such as mountaineering operations where flammable and explosive gases or dust are present, the explosion-proof motor can effectively prevent dangerous accidents such as explosions caused by electric sparks generated by the motor operation, thereby improving the safety of equipment use. The top of the blade body 601 is fixedly connected to a top cover 604 , and the liquid guiding tube 702 is located inside the top cover 604 . The top cover 604 protects the liquid guiding tube 702 and prevents it from being damaged.

[0034] The operation process of this embodiment is as follows: when it is necessary to break the mountain wall, the explosion-proof power motor 100 is first started to drive the central gear 205 to rotate, and then the planetary gear 204 is driven to rotate. The planetary gear 204 is meshed with the inner gear ring 201, and the power is transmitted to the drive shaft 202 through the gear seat 203. After that, the driving bevel gear 307 at the end of the driving shaft 202 is meshed with the driven bevel gear 309 in the lubrication chamber 301, and the power is transmitted to the rotating shaft 308. The driving gear 310 on the rotating shaft 308 drives the driven gear 312 to rotate. The second fixed shaft 314 on the edge of the driven gear 312 is connected to the connecting rod 315 pushes the sliding seat 303 to slide back and forth on the guide rod 302, and then drives the movable rod 402 to perform reciprocating linear motion in the sleeve 401 through the connecting rod 304, so that the wall-breaking knife 600 generates high-frequency vibration. Combined with the inverted tooth shape and three-row staggered structure of the crushing teeth 605, it can enhance the crushing ability of hard materials, expand the crushing range and improve uniformity. This structure realizes efficient power transmission through the combination of planetary gears 204 and driving bevel gears 307, which is adapted to the high-intensity requirements of mountain blasting and wall breaking; the special design of the crushing teeth 605 and the composite motion mode improve the crushing efficiency and uniformity.

[0035] Example 2 See also Figure 1 、 Figure 2 and Figure 5 On the basis of the specific embodiment 1, the flushing assembly 700 includes a water pump 701 fixedly connected to the top of the end cover 400 and a liquid guide tube 702 installed inside the placement groove 602. A connecting pipe 703 is connected between the output end of the water pump 701 and the liquid guide tube 702. The input end of the water pump 701 is installed with a water inlet pipe 704 for absorbing water. The water pump 701, the liquid guide tube 702, the connecting pipe 703 and the water inlet pipe 704 cooperate with each other to transport water and other cleaning liquids to the wall-breaking knife 600, thereby cooling the knife body 601, reducing dust, and flushing out debris.

[0036] The operating process of this embodiment is as follows: during the wall breaking process, the water pump 701 is first started, and then water is sucked through the water inlet pipe 704, and transported to the liquid guide pipe 702 installed in the placement groove 602 of the knife body 601 through the connecting pipe 703. The liquid is sprayed out from the water outlet 603. When the wall breaking knife 600 is running at high speed, the knife body 601 can be cooled in real time to avoid damage to the tool due to overheating due to friction. At the same time, the water flow can suppress the dust generated during the crushing process, improve the working environment, and flush the crushed debris out of the working area, reduce the accumulation of debris, and improve the wall breaking efficiency.
