Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, and particularly relates to a coal mine crushing device for coal mine machinery. Background Art

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. Generally, it is divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally, tunnels are dug underground to mine coal. When the distance between the coal seam and the surface is very close, generally, the surface soil layer is directly stripped to mine coal. The crushing device will crush the coal mine into different sizes. It is necessary to perform secondary crushing on larger coal mines, and after discharging, it is also necessary to screen the ore particles.

[0003] Publication No. CN215029354U discloses a coal mine crushing device for coal mine machinery, including a main body, a feed inlet and a box door. The feed inlet is integrally connected to the middle of the top of the main body. A first motor and a second motor are fixedly installed on the outer surface of the main body. A first main gear is movably connected inside the first motor. A crushing gear is rotatably connected outside the first main gear. A crushing roller is fixedly connected inside the crushing gear. A second main gear is movably connected inside the second motor. A pointed knife gear is rotatably connected outside the second main gear. A pointed knife roller is fixedly connected inside the pointed knife gear.

[0004] The above device can completely crush coal particles into smaller blocks, and the crushed coal particles will be filtered by a filter screen. When filtering, a small amount of large particle coal will stay on the upper surface of the filter screen. As the use time increases, a large amount of large particle coal will accumulate on the upper surface of the filter screen, and it is necessary for the staff to open the box door for cleaning, which is inconvenient to use.

Detailed Embodiment

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Such as Figure 1 Figure 2As shown in the figure, a coal crushing device for coal mining machinery includes a main body 2. At the upper end of the main body 2, a feed inlet 1 is fixedly installed. On the side wall of the main body 2, a device motor 3 is fixedly installed. At the bottom of the main body 2, a discharge outlet 5 is fixedly installed. Inside the main body 2, above the discharge outlet 5, a filter screen 4 is provided. Inside the main body 2, above the filter screen 4, an auxiliary mechanism 6 is provided. The auxiliary mechanism 6 includes a synchronous motor 601 fixed to the back of the main body 2. The output end of the synchronous motor 601 is connected to a trapezoidal lead screw 605. On the trapezoidal lead screw 605, a lead screw slider 603 is provided. Inside the main body 2, between the lead screw sliders 603, a cleaning mechanism 7 is provided. By the synchronous motor 601 on the auxiliary mechanism 6, the cleaning mechanism 7 can be driven to move forward. When the cleaning mechanism 7 moves forward, the cleaning brush 703 will rotate, thus quickly cleaning the large-particle coal on the filter screen 4 instead of manual labor, which is convenient for users to use.

[0024] As Figure 3 shown in the figure, the auxiliary mechanism 6 includes a synchronous motor 601 fixed to the back of the main body 2. The output end of the synchronous motor 601 is connected to a trapezoidal lead screw 605. On the trapezoidal lead screw 605, a lead screw slider 603 is provided. The auxiliary mechanism 6 further includes a waste outlet 607 opened on the front surface of the main body 2. Inside the waste outlet 607, a sealing side plate 606 is movably installed, and a sealing gasket is provided at the edge of the sealing side plate 606. Inside the main body 2, above the trapezoidal lead screw 605, a blocking plate 602 is fixedly installed. On the lead screw slider 603, a connecting through hole 604 is opened.

[0025] Specifically, after starting the synchronous motor 601, it will drive the trapezoidal lead screw 605 to rotate. After the trapezoidal lead screw 605 rotates, it will drive the lead screw slider 603 to move back and forth. After the lead screw slider 603 moves back and forth, it will drive the cleaning mechanism 7 to move forward. After the cleaning mechanism 7 moves forward, it will push the large-particle coal blocks swept up to the waste outlet 607, quickly cleaning the large-particle coal on the filter screen 4 out of the main body 2 instead of manual labor.

[0026] As Figure 4 shown in the figure, the cleaning mechanism 7 includes a first positioning seat 701 and a second positioning seat 704 fixed to the lead screw slider 603. Between the first positioning seat 701 and the second positioning seat 704, a drive shaft 702 is movably installed. On the drive shaft 702, a cleaning brush 703 is fixedly installed. The cleaning mechanism 7 further includes a drive motor 705 fixed to the second positioning seat 704. The output end of the drive motor 705 is fixedly installed with a first bevel gear 706. Bearings 708 are provided on both the first positioning seat 701 and the second positioning seat 704. One end of the drive shaft 702 is fixedly installed with a second bevel gear 707, and the first bevel gear 706 and the second bevel gear 707 are engaged together.

[0027] Specifically, the drive motor 705 drives the first helical gear 706 to rotate. After the first helical gear 706 rotates, it drives the second helical gear 707 to rotate. After the second helical gear 707 rotates, it drives the cleaning brush 703 on the drive shaft 702 to rotate. After the cleaning brush 703 rotates, it can automatically clean the surface of the filter screen 4.

[0028] It should be noted that the present utility model is a coal mine crushing device for coal mine machinery. During actual use, first, the sealing side plate 606 is opened, and then the drive motor 705 can be started. Since the first helical gear 706 and the second helical gear 707 are engaged together, both ends of the drive shaft 702 are movably installed on the first positioning seat 701 and the second positioning seat 704 through bearings 708 respectively. The cleaning brush 703 is movably installed above the filter screen 4 through the drive shaft 702, and the bristles on the cleaning brush 703 are in contact with the filter screen 4. Therefore, after the drive motor 705 is started, it drives the cleaning brush 703 to rotate. After the cleaning brush 703 rotates, it can automatically clean the surface of the filter screen 4. When the cleaning brush 703 rotates, the synchronous motor 601 can be started. Since there are bolts in the connecting through holes 604, the first positioning seat 701 and the second positioning seat 704 are respectively fixed on the screw rod sliders 603 on both sides through bolts. Therefore, after the synchronous motor 601 is started, it drives the cleaning mechanism 7 to move forward. After the cleaning mechanism 7 moves forward, it pushes the large coal blocks swept up to the waste outlet 607, replacing manual labor to quickly clean the large coal particles on the filter screen 4 outside the main body 2. After the large coal particles are cleaned outside the main body 2, the cleaning brush 703 can be controlled to reset, and the sealing side plate 606 can be closed.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
