Description

Technical Field

[0001] This utility model relates to the technical field of coal mine crushing and processing equipment, and in particular to a coal mine crushing device that is easy to clean. Background Technology

[0002] In coal mining operations, because the raw ore extracted is large in volume and inconvenient for subsequent processing and use, it is often necessary to crush the coal into smaller pieces to facilitate transportation and subsequent processing. Coal crushing equipment is used to crush large pieces of coal or coal gangue extracted during the coal mining process into smaller particles.

[0003] To this end, patent CN219424568U discloses a coal mine crushing device, including a crusher. A base is provided at each of the four corners of the crusher's bottom. A protective sleeve is fitted over the base. A movable wheel is provided at the bottom of the base. A sliding rod is provided on the inner wall of the protective sleeve. A sliding groove is formed inside the base. The sliding rod extends through the side wall of the base into the sliding groove. This invention allows the crusher to move via the movable wheel, eliminating the need for vehicles or other tools and facilitating personnel handling. The protective sleeve protects the movable wheel and ensures contact between the bottom of the protective sleeve and the ground, limiting movement around the bottom of the crusher and preventing it from shifting during operation.

[0004] The existing technical solutions described above have the following drawbacks: Although the crusher can be moved, it is inconvenient to clean the crushing rollers, resulting in crushed coal slag adhering to the rollers. Current cleaning methods mostly rely on manual labor, which is not only inefficient but also requires personnel to work in environments with inherent safety risks, making it difficult to adequately guarantee their personal safety. The long-term accumulation of slag not only affects the normal operation of the crushing rollers and reduces crushing efficiency but may also lead to accelerated equipment wear, shortening the equipment's service life and negatively impacting the overall efficiency of coal mining. Utility Model Content

[0005] The purpose of this invention is to provide a coal mine crushing device that is easy to clean, in order to solve the problem that existing coal mine crushing devices are inconvenient to clean the crushing rollers.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a coal mine crushing device that is easy to clean, including a crusher body;

[0007] A first guide plate is fixedly connected to the inner wall of the crusher body, a second guide plate is fixedly connected to the inner wall of the crusher body, and a crushing roller is installed inside the crusher body.

[0008] A cleaning mechanism is fixedly connected to the outer wall of the crusher body, and a guide plate is fixedly connected to the outer wall of the crusher body;

[0009] The cleaning mechanism includes a frame plate fixedly installed on one side of the crusher body, a drive motor fixedly connected to the outer wall of the frame plate, and a support rod movably installed inside the crusher body, with a cleaning brush fixedly connected to one end of the support rod.

[0010] The output shaft of the drive motor is fixedly connected to a rotating rod via a coupling. A gear is fixedly connected to the outer wall of the rotating rod. A rack is movably connected to the outer wall of the gear. A support frame is fixedly connected to the outer wall of the rack. A support plate is fixedly connected to the outer wall of the support frame. The support plate is welded to the other end of the supporting rod.

[0011] Preferably, the gear forms a rotating structure with the frame plate via a rotating rod, and the gear meshes with the rack.

[0012] Preferably, the rack and guide plate form a sliding structure, the guide plate is L-shaped, the receiving rod and crusher body form a sliding structure, and the receiving rod is symmetrically arranged about the central axis of the cleaning brush.

[0013] Preferably, the first guide plate and the second guide plate are arranged in parallel, and the second guide plate is arranged symmetrically about the central axis of the crusher body.

[0014] Preferably, a limiting mechanism is installed on the outer wall of the crusher body, a threaded groove is opened inside the crusher body, a threaded column is movably connected inside the threaded groove, a limiting block is fixedly connected to the outer wall of the threaded column, and a collection box is movably installed inside the crusher body.

[0015] Preferably, the threaded column is threadedly connected to the crusher body through a threaded groove, the limiting block forms a rotating structure with the crusher body through the threaded column, the crusher body and the collecting box form a sliding structure, and the collecting box and the limiting block are movably connected.

[0016] The coal mine crushing device provided by this utility model is easy to clean, and its advantages are as follows:

[0017] The crusher body, first guide plate, second guide plate, crushing roller, and cleaning mechanism are configured. By starting the drive motor, the rotating rod can be rotated, which in turn drives the gear to rotate. Since the gear meshes with the rack, the rack can slide along the guide plate, which in turn moves the support plate fixedly connected to the outer wall of the receiving frame. This causes the cleaning brush fixedly connected to one end of the receiving rod to move and come into contact with the crushing roller. Starting the crusher body can rotate the crushing roller, which in turn drives the cleaning brush to clean the coal dust attached to the gaps in the crushing roller, thus facilitating the cleaning of the crushing roller.

[0018] Furthermore, the first guide plate prevents the cleaned dust from escaping from the feed inlet of the crusher body, while the second guide plate allows the cleaned coal fragments to fall onto the second guide plate and slide into the collection box, thus collecting the cleaned coal fragments.

[0019] Furthermore, once the cleaning is complete, the drive motor is started to reverse the gears, causing the cleaning brush to separate from the crushing roller, thus not affecting the normal crushing operation of the coal mine.

[0020] By setting up a crusher body, a collection box, and a limiting mechanism, by pulling the limiting block, under the action of the threaded column, the limiting block can be rotated 90° along the crusher body and the limiting of the collection box can be released. Pulling the collection box allows it to slide out along the crusher body, which can remove the cleaned coal mine debris.

[0021] Furthermore, after the collection box slides into the crusher body, the limiting block is rotated. Since the threaded column is threadedly connected to the crusher body through the threaded groove, the limiting block can rotate back 90° and block and limit the outer wall of the collection box.

[0030] Please see Figures 1-6 The present invention provides a coal mine crushing device that is easy to clean, including a crusher body 1.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first guide plate 2 is fixedly connected to the inner wall of the crusher body 1, and a second guide plate 3 is fixedly connected to the inner wall of the crusher body 1. A crushing roller 4 is installed inside the crusher body 1. The first guide plate 2 and the second guide plate 3 are arranged parallel to each other, and the second guide plate 3 is symmetrically arranged about the central axis of the crusher body 1. A cleaning mechanism 5 is fixedly connected to the outer wall of the crusher body 1, and a guide plate 6 is fixedly connected to the outer wall of the crusher body 1. The cleaning mechanism 5 includes a frame plate 51 fixedly installed on one side of the crusher body 1, and a drive motor 52 is fixedly connected to the outer wall of the frame plate 51. The cleaning mechanism 5 also includes a receiving rod 58 movably installed inside the crusher body 1, and one end of the receiving rod 58 is fixed. A cleaning brush 59 is connected to the output shaft of a drive motor 52, which is fixedly connected to a rotating rod 53 via a coupling. A gear 54 is fixedly connected to the outer wall of the rotating rod 53, and a rack 55 is movably connected to the outer wall of the gear 54. A support frame 56 is fixedly connected to the outer wall of the rack 55, and a support plate 57 is fixedly connected to the outer wall of the support frame 56. The support plate 57 is welded to the other end of the support rod 58. The gear 54 forms a rotating structure with the frame plate 51 via the rotating rod 53. The gear 54 meshes with the rack 55, and the rack 55 forms a sliding structure with the guide plate 6. The guide plate 6 is L-shaped. The support rod 58 forms a sliding structure with the crusher body 1. The support rod 58 is symmetrically arranged about the central axis of the cleaning brush 59.

[0032] By starting the drive motor 52, the rotating rod 53 can be rotated, which in turn drives the gear 54 to rotate. Since the gear 54 is meshed with the rack 55, the rack 55 can slide along the guide plate 6, which drives the support plate 57 fixedly connected to the outer wall of the receiving frame 56 to move. This causes the cleaning brush 59 fixedly connected to one end of the receiving rod 58 to move, so that the cleaning brush 59 contacts the crushing roller 4. Starting the crusher body 1 can make the crushing roller 4 rotate, which drives the cleaning brush 59 to clean the coal mine dust attached to the gap of the crushing roller 4. Under the action of the first guide plate 2, the cleaning dust can be prevented from being scattered from the feed port of the crusher body 1. Under the action of the second guide plate 3, the cleaned coal mine dust can fall onto the second guide plate 3 and slide into the collection box 7. After cleaning is completed, starting the drive motor 52 causes the gear 54 to reverse, which drives the cleaning brush 59 to separate from the crushing roller 4, so as not to affect the normal crushing operation of the coal mine.

[0033] Reference Figure 1 , Figure 5 and Figure 6 As shown, a limiting mechanism 8 is installed on the outer wall of the crusher body 1. A threaded groove 81 is opened inside the crusher body 1. A threaded column 82 is movably connected inside the threaded groove 81. A limiting block 83 is fixedly connected to the outer wall of the threaded column 82. A collection box 7 is movably installed inside the crusher body 1. The threaded column 82 is threadedly connected to the crusher body 1 through the threaded groove 81. The limiting block 83 forms a rotating structure with the crusher body 1 through the threaded column 82. The crusher body 1 and the collection box 7 form a sliding structure. The collection box 7 is movably connected to the limiting block 83.

[0034] By pulling the limiting block 83, under the action of the threaded column 82, the limiting block 83 can be rotated 90° along the crusher body 1 and the limiting of the collection box 7 can be released. Pulling the collection box 7 can make it slide out along the crusher body 1, so that the cleaned coal mine dust can be removed. When the collection box 7 slides into the crusher body 1, rotating the limiting block 83, since the threaded column 82 is threadedly connected to the crusher body 1 through the threaded groove 81, can make the limiting block 83 rotate back 90° and block and limit the outer wall of the collection box 7.

[0035] Although the present invention 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 make equivalent substitutions for some of the technical features.
