Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a coal and rock crushing device for mining. Background Technology

[0002] A coal mine is an area where humans extract coal resources in coal-rich mining areas. It is generally divided into underground coal mines and open-pit coal mines. A coal mine is a reasonable space excavated by humans when excavating geological layers rich in coal. It usually includes roadways, shafts, and mining faces. During the coal mining process, the large volume of coal and rock is not conducive to transportation and subsequent reprocessing. Therefore, coal and rock crushing devices are often used to crush coal and rock during coal mining.

[0003] A search revealed a coal mining crushing device in patent publication number CN222000051U, which states that "after crushing by crushing rollers, qualified coal blocks flow out through a filter screen, while some unqualified coal blocks are piled on the filter screen. The drive motor works, driving the belt to rotate through the transmission mechanism, which in turn drives the brush plate to sweep the coal blocks on the filter screen into the circulation inlet. The screw feeder then feeds the coal blocks back into the crushing box through the circulation outlet for secondary or multiple crushing until they are qualified, which then passes through the filter screen and flows out through the discharge port. This eliminates the need for manual sorting, further improving the overall crushing efficiency and performance."

[0004] However, the above-mentioned solutions still have certain shortcomings in actual use. During the feeding process of coal mines, a large amount of dust will be filled in the air, and the coal blocks will cause large-scale dust during the stirring process, which can easily affect the health of the surrounding workers to a certain extent.

[0025] 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.

[0026] Please see Figure 1-5 This utility model discloses a coal and rock crushing device for mining, including an installation mechanism 1. A crushing device 2 is fixedly installed at the top of the installation mechanism 1, and a dustproof device 3 is movably connected to the feed inlet of the crushing device 2.

[0027] The installation mechanism 1 includes a placement frame 101, a feeding channel 102 is fixedly installed on the inner side of the placement frame 101, a receiving tray 103 and a guide ramp 104 are fixedly installed on the inner wall of the feeding channel 102, and the guide ramp 104 is located below the receiving tray 103.

[0028] The crushing device 2 includes a housing 201, a transmission device 202 is provided on the outer side of the housing 201, and a crushing roller 203 is rotatably connected to the inner side of the housing 201. The transmission device 202 is connected to the crushing roller 203.

[0029] The transmission device 202 includes a built-in motor and a transmission disc, which are connected to each other by a transmission belt.

[0030] The dustproof device 3 includes a sealing plate 301. An exhaust fan 303 and a purification structure 305 are fixedly installed on the inner wall of the sealing plate 301. An air inlet pipe 304 is fixedly installed at the air inlet end of the exhaust fan 303, and a purification structure 305 is fixedly installed at the air outlet end of the exhaust fan 303.

[0031] The purification structure 305 includes a purification box 306. A partition 307 is fixedly installed inside the purification box 306. The partition 307 divides the inner cavity of the purification box 306 into a dust settling chamber 308 and a filter chamber 309. A communication port is opened inside the partition 307, and the dust settling chamber 308 and the filter chamber 309 are connected through the communication port. An air outlet pipe 310 is fixedly installed at the top of the purification box 306.

[0032] An external water tank 311 is fixedly installed on the outside of the purification box 306. A nozzle 312 is fixedly connected to the bottom of the external water tank 311. The nozzle 312 extends into the interior of the dust settling chamber 308. A dust settling box 313 is movably engaged inside the dust settling chamber 308.

[0033] A plug-in block 314 is fixedly installed inside the filter chamber 309, and a filter plate 315 is movably plugged into the plug-in block 314.

[0034] The sealing plate 301 can close the feed inlet of the crushing device 2. In conjunction with the exhaust fan 303, the generated dust is drawn into the purification box 306 through the air inlet pipe 304. The nozzle 312 sprays water from the external water tank 311 onto the gas in the dust settling chamber 308, which helps to settle large particles of impurities in the gas. In addition, the multi-layer filter plate 315 can purify the gas after dust settling. This design not only improves the dust purification efficiency, but also greatly reduces the potential safety hazards caused by dust, ensuring a safe and clean working environment.

[0035] Specifically, the top of the sealing plate 301 is movably latched with an inspection cover 302, the specifications of which are adapted to the size of the feed inlet of the crushing device 2.

[0036] In this embodiment, the inspection cover 302 facilitates the inspection and maintenance of the dustproof device 3 by personnel, ensuring its normal operation. Simultaneously, the inspection cover 302 is compatible with the feed inlet size of the crushing device 2, allowing for a tight fit and preventing dust from escaping through gaps, further improving the dustproof effect.

[0037] Specifically, an external handle 316 is fixedly connected to the side of the filter plate 315 away from the plug block 314, and the external handle 316 extends to the outside of the purification box 306.

[0038] In this implementation scheme, the external handle 316 facilitates the replacement or cleaning of the filter plate 315 by staff, ensuring the filtration effect of the filter plate 315 and improving the ease of operation for staff. During use, after prolonged use, a certain amount of dust and impurities will accumulate on the surface of the filter plate 315, leading to a decrease in filtration efficiency. At this time, staff can pull the external handle 316 to remove the filter plate 315 from the insertion block 314 for replacement or cleaning, making the operation simple and quick.

[0039] In use, first, the coal and rock to be crushed are put into the housing 201 of the crushing device 2. The transmission device 202 is started, the built-in motor works, and the transmission disc is driven to rotate through the transmission belt, which in turn drives the crushing roller 203 to rotate inside the housing 201 to crush the coal and rock.

[0040] During the coal and rock crushing process, the dustproof device 3 is placed over the feed inlet of the housing 201, causing the sealing plate 301 to seal the feed inlet of the crushing device 2, preventing dust leakage. Simultaneously, the exhaust fan 303 starts, drawing the generated dust into the purification box 306 through the air intake pipe 304. The nozzles 312 inside the purification box 306 spray water from the external water tank 311 onto the gas in the dust suppression chamber 308, thus suppressing large particles in the gas. The dust-suppressed gas enters the filter chamber 309 through the connecting port on the partition 307, undergoes purification treatment by multiple layers of filter plates 315, and is finally discharged from the exhaust pipe 310, ensuring a clean and safe working environment.

[0041] After being crushed, the coal and rock will eventually enter the feeding channel 102 and be discharged outward along the guide plate 104 and the receiving plate 103.

[0042] Furthermore, when the dust control device 3 needs inspection or maintenance, simply open the inspection cover 302. Similarly, when the filter plate 315 needs replacement or cleaning, workers can easily pull the filter plate 315 out of the insertion block 314 by pulling the external handle 316. The design of this mining coal and rock crushing device not only improves the dust purification efficiency but also greatly enhances the convenience and safety of operation.

[0043] Furthermore, the purification box 306 is made of a corrosion-resistant and high-temperature-resistant alloy material. In this embodiment, since the interior of the purification box 306 needs to withstand the scouring of high-temperature gases and liquids, and also needs to be corrosion-resistant, selecting a corrosion-resistant and high-temperature-resistant alloy material as the material for the purification box 306 can ensure its service life and stability. At the same time, the alloy material also has good mechanical properties and processing performance, facilitating manufacturing and processing.

[0044] The dust collection box 313 is designed to collect the dust and water droplets deposited in the dust collection chamber 308, facilitating regular cleaning by staff and maintaining the cleanliness and unobstructed flow of the dust collection chamber 308. The dust collection box 313 and the dust collection chamber 308 are connected by a snap-fit ​​mechanism, which facilitates disassembly and installation, improving operational convenience.

[0045] In summary, this mining coal and rock crushing device utilizes a sealing plate 301 to close the feed inlet of the crushing device 2. Combined with a blower 303, the generated dust is drawn into the purification box 306 through the air inlet pipe 304. This causes the nozzle 312 to spray water from the external water tank 311 onto the gas in the dust suppression chamber 308, thus reducing large particles in the gas. Furthermore, the multi-layer filter plate 315 further purifies the dust-suppressed gas. This design not only improves dust purification efficiency but also significantly reduces potential safety hazards caused by dust, ensuring a safe and clean working environment.

[0046] It should be noted that the model and specifications of the transmission equipment 202, exhaust fan 303 and nozzle 312 in the coal and rock crushing device for mining need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0047] Furthermore, the power supply and operating principle of the transmission device 202, the exhaust fan 303, and the nozzle 312 in the mining coal and rock crushing device are clear to those skilled in the art and will not be described in detail here.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
