[0002] The belt pear-type coal scraper is also called coal plow for short. It mainly includes a belt conveyor and a pear-type coal scraper component. The coal to be unloaded is transported through the belt on the belt conveyor. Through the pear-type coal scraper component, with a cylinder or other energy as the power source, the telescopic rod of the cylinder extends to drive the plow head to descend, which can scrape the coal on the belt. It is widely used in power plants, coal-fired plants and other places.

[0003] Existing belt pear-type coal scrapers can basically meet the needs of use. However, during use, the belt pear-type coal scraper has only one pear-type coal scraper component. When the material on the belt of the conveyor belt passes through the pear-type coal scraper component, it cannot be completely unloaded. It is often necessary to set a belt conveyor device on the side of the belt pear-type coal scraper to transport the remaining coal to the belt conveyor for coal return. Therefore, the belt conveyor device needs to be started at the same time when the belt pear-type coal scraper is working, which increases the maintenance cost of the equipment to a certain extent. In addition, the belt pear-type coal scraper is often unable to scrape the coal on the belt cleanly, and the coal unloading effect needs to be improved. Based on this, the utility model provides a belt pear-type coal scraper with reduced maintenance costs. Utility Model Content

[0004] The technical problem solved by the utility model is that when the belt pear-type coal scraper is working, the belt conveyor device on one side thereof needs to be started simultaneously, which increases the maintenance cost of the equipment. The belt pear-type coal scraper is often unable to scrape the coal on the belt clean, and the coal unloading effect needs to be improved.

[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a belt pear-type coal scraper with reduced maintenance costs, including a belt conveyor, the belt conveyor including a bracket, a belt arranged between the brackets, a pear-type coal scraping component is provided on one side of the top of the bracket, and a coal scraping and sweeping component is provided on the top of the bracket and is placed on one side of the pear-type coal scraping component, the coal scraping and sweeping component includes a support plate, a mounting plate is provided on the top of the support plate, a cylinder is provided at the four corners of the top of the mounting plate, a lifting plate is provided between the ends of the telescopic rod of the cylinder, V-shaped scraping plates are symmetrically provided on both sides below the lifting plate, L-shaped plates are symmetrically provided on both side walls of the lifting plate, a cleaning roller placed between the V-shaped scraping plates is rotatably connected between the L-shaped plates, and a motor for driving the cleaning roller to rotate is provided on the outer wall of the L-shaped plate on one side.

[0006] Furthermore, both ends of the cleaning roller are provided with a rotating rod rotatably connected to the side wall of the L-shaped plate, and the output end of the motor is fixedly connected to one end of the rotating rod.

[0007] Furthermore, the support plate is symmetrically fixed on the top of the bracket, and the end of the telescopic rod of the cylinder passes through the mounting plate and is fixedly connected to the top of the lifting plate.

[0008] Furthermore, support rods are symmetrically provided between the bottom of the lifting plate and the top of the V-shaped coal scraper plate.

[0009] Furthermore, the V-shaped coal scraper and the cleaning roller are both placed above the belt, and the roller body of the cleaning roller is provided with a cleaning brush strip that fits the belt surface.

[0010] Beneficial effects of the utility model:

[0011] The V-shaped coal scraper is raised and lowered to fit the upper surface of the belt through the coal scraping and sweeping components. At this time, the cleaning brush is in contact with the belt surface. The motor is started to rotate the cleaning roller and the cleaning brush, thereby sweeping away the fine particles of coal slag adhering to the belt surface. When the belt is being conveyed, the belt that has been scraped off the coal by the pear-shaped coal scraper is further scraped off by the V-shaped coal scrapers on both sides, which can further scrape off the residual and adhering coal on the belt. There is no need to add a belt conveyor for coal return work, which can effectively reduce the maintenance cost of the equipment to prevent residual coal from entering the belt conveyor. The coal on the belt can be scraped clean, and the coal unloading effect is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS
