The cross-section of the welding plate 301 is "U"-shaped. A screw rod 302 is slidably penetrated on the surface of the welding plate 301. The upper end of the screw rod 302 is rotatably connected to a scraper 303. The arc surface of the screw rod 302 is threadedly connected to a driven bevel gear 305.

The active bevel gear The wheel 304 is meshed with the driven bevel gear 305, and the other end of the rotating rod 306 is fixedly connected to the connecting plate 307. The side of the connecting plate 307 away from the rotating rod 306 is fixedly connected to the handle 308. The arc surface of the rotating rod 306 is threadedly connected to the adjusting ring 309. By setting the decontamination structure 3, after the material conveying belt conveyor used in coal mining is used, the personnel can conveniently adjust the scraper 303 to scrape the dirt on the conveyor belt 8. The timely removal of dirt and coal dust can reduce the wear of the conveyor belt 8 and other components and extend the service life of the equipment. 1 is fixedly connected to the inner wall of the baffle 312, the cross section of the baffle 312 is dovetail-shaped, and the baffle 312 is slidably connected to the screw rod 302. When the scraper 303 is used to scrape the dirt on the conveyor belt 8, the dirt on the conveyor belt 8 falls on the inclined surface of the baffle 312. The dirt will fall along the inclined surface of the baffle 312 due to its own gravity. The baffle 312 can prevent the dirt from falling on the parts on the welding plate 301. The surface of the welding plate 301 is slidably penetrated by a guide rod 311. The upper end of the guide rod 311 is fixedly connected to the lower surface of the scraper 303. The guide rod 311 is fixedly connected to the baffle. 312 is a sliding connection. When the screw rod 302 rotates to drive the scraper 303, the guide rod 311 can guide and position the scraper 303, thereby preventing the scraper 303 from rotating and deviating during its movement. A rubber pad 310 is fixedly connected to the side of the adjustment ring 309 close to the welding plate 301. One side of the rubber pad 310 abuts against the welding plate 301. The rubber pad 310 can increase the friction force of the side of the adjustment ring 309 close to the welding plate 301, thereby ensuring that the adjustment ring 309 can abut against the welding plate 301 with the help of the rubber pad 310.

[0036] In the embodiments of the present invention, please refer to Figure 6The storage structure 4 includes a storage box 41. One side of the storage box 41 is fitted with the welding plate 301.

The upper end of the short arm end of the limit rod 43 is fixedly connected to the lower surface of the welding plate 301. A pressure rod 45 is threadedly penetrated on the lower surface of the limit plate 44. One end of the pressure rod 45 abuts against the arc surface of the limit rod 43. By setting the storage structure 4, the storage box 41 can collect the dirt on the conveyor belt 8 scraped by the scraper 303 to prevent the dirt from falling on the ground and polluting the surrounding environment. The storage box 41 is conveniently disassembled and assembled by personnel, thereby facilitating the unified transportation of dirt. A handle 42 is fixedly connected to the side of the storage box 41 away from the welding plate 301. The cross section of the handle 42 is "U"-shaped. Moving the handle 42 can drive the storage box 41, thereby achieving the effect of convenient control of the storage box 41. A guide block 46 is fixedly connected to the side of the limiting rod 43 away from the welding plate 301. The guide block 46 has a conical structure. Since the guide block 46 fixed to one end of the limiting rod 43 is small in size, the limiting plate 44 can be easily sleeved on the arc surface of the limiting rod 43.

[0037] The working principle of a material conveying belt conveyor used in coal mining provided by the present invention is as follows: when it is necessary to use a conveyor belt 8 to transport coal, first start the servo motor 5 to drive the active roller 6 to rotate, the active roller drives the conveyor belt 8, and the conveyor belt 8 drives the driven roller to rotate, and then the coal to be transported is dumped on one side of the conveyor belt 8, so that the coal can be transported with the help of the belt conveyor. In the process of transporting coal by the conveyor belt 8, waste slag and other dirt are easily attached to the conveyor belt 8. When it is necessary to use the decontamination structure 3 to remove the dirt on the conveyor belt 8, first rotate the adjusting ring 309 to drive The rubber pad 310 is separated from the welding plate 301, so that it can contact the limit of the rotating rod 306, and then the servo motor 5 is started to drive the active roller 6 to rotate at a low speed, and the active roller 6 drives the belt to rotate at a low speed, and then the handle 308 is rotated to drive the connecting plate 307, and the connecting plate 307 drives the rotating rod 306 to rotate, and the rotating rod 306 drives the active bevel gear 304 to rotate, and the active bevel gear 304 drives the driven bevel gear 305 to rotate, and the driven bevel drives the screw rod 302, so that the screw rod 302 drives the baffle 312 to move in the direction close to the conveyor belt 8. When the baffle 312 contacts the conveyor belt 8, the handle 308 can be stopped. 08 rotates, at this time the baffle 312 can scrape the dirt on the conveyor belt 8. When the conveyor belt 8 is cleaned, the connecting plate 307 is rotated in the opposite direction with the help of the handle 308. The connecting plate 307 drives the rotating rod 306 to rotate in the opposite direction. The rotating rod 306 drives the active bevel gear 304. The active bevel gear 304 drives the driven bevel gear 305 to rotate in the opposite direction. The driven bevel gear 305 drives the baffle 312 to return to its original position. In the process of using the scraper 303 to scrape the dirt on the conveyor belt 8, the dirt on the conveyor belt 8 falls on the inclined surface of the baffle 312. The dirt will fall along the inclined surface of the baffle 312 due to its own gravity. The baffle 312 can prevent dirt from falling on the parts on the welding plate 301. In the process of the screw rod 302 rotating to drive the scraper 303, the guide rod 311 can guide and position the scraper 303, thereby preventing the scraper 303 from rotating and offsetting during its movement. In addition, the rubber pad 310 can increase the friction of the adjustment ring 309 close to the welding plate 301, thereby enabling the adjustment ring 309 to be firmly in contact with the welding plate 301 with the help of the rubber pad 310. Rotating the adjustment ring 309 drives the rubber pad 310 to abut against the welding plate 301, thereby limiting the rotating rod 306.

[0038] When using the scraper 303 to scrape the dirt on the conveyor belt 8, the dirt on the conveyor belt 8 will fall into the storage box 41 along the inclined surface of the baffle 312. When the storage box 41 is full, the personnel can disassemble the storage box 41 to uniformly transport the dirt. The specific steps are as follows: first, rotate the pressure rod 45 on the limit plate 44 to separate the pressure rod 45 from the arc surface of the limit rod 43, and then move the handle 42 to drive the storage box 41 so that the storage box 41 drives the limit plate 44 to separate from the limit rod 43. Then, the personnel can move the storage box 41. The box 41 uniformly transports the dirt inside it. When the dirt is dumped and recovered, the handle 42 is moved to drive the empty storage box 41, and the limit plate 44 on the storage box 41 is put on the arc surface of the limit rod 43. When one side of the storage box 41 is in contact with the welding plate 301, the pressure rod 45 is rotated to abut against the limit rod 43 to complete the installation limit of the storage box 41. Since the guide block 46 fixed at one end of the limit rod 43 is relatively small, the limit plate 44 can be easily put on the arc surface of the limit rod 43.
