[0033] The cleaning mechanism 3 is arranged at the bottom of the conveying mechanism 2 and the inner top of the fixing mechanism 1 and is used for cleaning the conveying mechanism 2 .

[0034] In order to conveniently clean the surface of the conveying mechanism 2 so that the conveying mechanism 2 can stably convey the coal, Figure 2-3 and Figure 5 As shown, the cleaning mechanism 3 includes a mounting plate 301 and a rotating shaft 304, both ends of one side of the bottom of the mounting plate 301 are fixedly mounted with movable racks 302, the rotating shaft 304 is arranged on an inner wall of one side of the inner side of the fixing mechanism 1, one end of the rotating shaft 304 is provided with a second motor 305, both ends of the outer walls of the rotating shaft 304 are fixedly sleeved with rotating gears 306, the two rotating gears 306 are respectively meshed with the two movable racks 302, two traction springs 308 are arranged on the inner walls of both ends of the top of the mounting plate 301, and a clamping plate 309 is fixedly mounted on the end of the traction spring 308 away from the inner wall of the mounting plate 301, and the clamping plate 309 is close to the traction spring A fastening bolt 310 is arranged between one end of 308 and the inner wall of the mounting plate 301, a cleaning brush 311 is arranged on the inner side of the four clamping plates 309 at one end, and a scraper 312 is arranged on the inner side of the four clamping plates 309 at the other end. The clamping plates 309 can clamp the cleaning brush 311 or the scraper 312 under the elastic force of the traction spring 308, and the rotating shaft 304 is rotated by the operation of the second motor 305. Through the meshing action between the rotating gear 306 and the movable rack 302, the height of the cleaning brush 311 and the scraper 312 can be adjusted, so that the cleaning brush 311 and the scraper 312 can clean the surface of the conveying mechanism 2.

[0035] In order to keep the cleaning brush 311 and the scraper 312 stable during the height adjustment process, Figure 2 and Figure 4-5As shown, the fixing mechanism 1 includes a fixing frame 101, and mounting seats 102 are fixedly installed on both sides of the top of the fixing frame 101. Limiting grooves 103 are opened on the inner walls at both ends of the inner side of the fixing frame 101. Limiting plates 303 are fixedly installed on one side of the two ends of the bottom of the mounting plate 301 away from the movable rack 302. The outer wall of the limiting plate 303 is movably connected to the inner wall of the adjacent limiting groove 103. The limiting groove 103 can limit the movement of the limiting plate 303, so that the mounting plate 301 remains stable during the height adjustment process, and the cleaning brush 311 and the scraper 312 can stably clean the conveying mechanism 2.

[0036] In order to conveniently install the conveying mechanism 2, Figure 2 and Figure 4 As shown, the conveying mechanism 2 includes two rotating rollers 201, and the two rotating rollers 201 are rotatably mounted on the two ends of the inner side of two mounting seats 102 respectively. A conveying belt 203 is arranged on the outer side of the two rotating rollers 201. A first motor 202 is fixedly mounted on the outer wall of one side of one of the mounting seats 102. The first motor 202 is connected to one of the rotating rollers 201 through an output shaft transmission connection. The mounting seat 102 can install and fix the rotating rollers 201 and the first motor 202. The operation of the first motor 202 causes the adjacent rotating rollers 201 to rotate, thereby allowing the conveying belt 203 to transport the coal.

[0037] In order to keep the clamping plate 309 stable during the adjustment process, Figure 2-3 and Figure 5 As shown, movable grooves 307 are provided on the inner walls at both ends of the top of the mounting plate 301, and the two ends of the inner wall of the movable groove 307 are respectively fixedly connected to the two adjacent traction springs 308, and the two ends of the inner wall of the movable groove 307 are respectively movably connected to the bottom outer walls of the two adjacent clamping plates 309, and the inner walls at both ends of the movable groove 307 are respectively threadedly connected to the two adjacent fastening bolts 310, and the end of the fastening bolt 310 away from the inner wall of the movable groove 307 is abutted and connected to the adjacent clamping plate 309, and the fastening bolt 310 is movably inserted into the inner side of the adjacent traction spring 308. The movable groove 307 can limit the movement of the clamping plate 309, so that the clamping plate 309 remains stable during the adjustment process, so that the clamping plate 309 can stably clamp and fix the cleaning brush 311 and the scraper 312, and the setting of the fastening bolt 310 can reinforce the clamping of the clamping plate 309.

[0038] In order to make the cleaning of the conveying mechanism 2 more thorough, Figure 2As shown, a cleaning brush 311 is arranged at the bottom of the feed end of the conveyor belt 203, and a scraper 312 is arranged at the bottom of the discharge end of the conveyor belt 203. The tops of the cleaning brush 311 and the scraper 312 are connected to the bottom of the conveyor belt 203. The scraper 312 first removes coal slag from the surface of the conveyor belt 203, and then the cleaning brush 311 can be used to clean the conveyor belt 203 after preliminary cleaning, so that the cleaning of the conveyor belt 203 is more thorough.

[0039] The specific implementation method is as follows: when transporting coal, the cleaning brush 311 and the scraper 312 are respectively placed at the two ends of the top of the mounting plate 301, so that the cleaning brush 311 can be at the feeding port of the conveying mechanism 2, and the scraper 312 is at the discharging port of the conveying mechanism 2. The cleaning brush 311 and the scraper 312 will squeeze the clamping plate 309, so that the clamping plate 309 moves toward the two ends along the inner wall of the movable groove 307, thereby causing the adjacent traction spring 308 to contract. When the cleaning brush 311 and the scraper 312 are placed, the four ends of one end The clamping plate 309 clamps the cleaning brush 311 under the elastic force of the traction spring 308, and the four clamping plates 309 at the other end clamp the scraper 312, and then the clamping of the clamping plate 309 can be reinforced by the fastening bolt 310 penetrating the inner wall of the movable groove 307 and contacting and connecting the adjacent clamping plates 309, and then the adjacent rotating roller 201 is rotated by the operation of the first motor 202, so that the conveying belt 203 can convey the coal mine. When conveying the coal mine, the surface of the conveying belt 203 will adhere to There is coal slag, and the second motor 305 is operated to make the rotating shaft 304 rotate, so that the two rotating gears 306 rotate, and through the meshing action between the gear parts, the two movable racks 302 move upward, and then the mounting plate 301 can be driven to move upward. At the same time, the limiting groove 103 can limit the movement of the limiting plate 303, so that the mounting plate 301 remains stable during the height adjustment process, so that the cleaning brush 311 and the scraper 312 can contact the bottom of the conveyor belt 203, and then as the conveyor belt 203 is conveyed, the scraper 312 can scrape off the coal slag on the surface of the conveyor belt 203. After the scraped conveyor belt 203 passes the position of the cleaning brush 311, the cleaning brush 311 can clean the scraped conveyor belt 203, so that the surface of the conveyor belt 203 remains tidy, and the cleaning of the conveyor belt 203 is more thorough, which can avoid the situation where a large amount of coal slag remains on the surface of the conveyor belt 203 and causes the conveyor belt to deviate. This embodiment specifically solves the problem in the prior art that the surface of the coal conveyor belt cannot be fully cleaned, resulting in the coal slag residue causing the belt to deviate.

[0040] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
