[0002] Crusher equipment is a crucial tool in the process of mining and processing in mines. It is mainly used to crush large pieces of ore or other materials mined out for further processing and utilization. The crusher equipment uses a high-speed rotating hammer head to strike the materials, causing them to be crushed along natural planes such as cracks and joint surfaces. When crushing sticky and wet materials, it is easy to block the screen slots of the grizzly bar, thus easily causing the machine to stop (the water content of the materials should not exceed 10%). Due to the easy occurrence of coal sticking and coal accumulation in the inner cavity of the crusher in the related art, the crusher is prone to blockage problems, resulting in a reduction in production capacity.

[0030] A cleaning device for a slime crusher, as Figure 1 shown, includes a cleaning structure, a driving mechanism, and a cylinder structure; the cleaning structure is arranged inside the cylinder structure, the driving mechanism is arranged outside the cylinder structure, and the driving mechanism is used to rotate the cleaning structure;

[0031] The cleaning structure includes a scraper assembly 101, a transmission structure, a first support plate 103, and a second support plate 105. The scraper assembly 101 is a cylindrical structure. The first support plate 103 and the second support plate 105 are symmetrically arranged on the front and rear sides of the scraper assembly 101, and the driving mechanism drives the scraper assembly 101 to rotate through the transmission structure; the cleaning structure and the cylinder structure are coaxially arranged.

[0032] As Figure 2As shown in the figure, the scraper assembly 101 includes a first flange plate 1012, a second flange plate 1013, and a plurality of scrapers 1011. The first flange plate 1012 and the second flange plate 1013 are symmetrically arranged up and down. The plurality of scrapers 1011 are evenly arranged in a circular pattern between the first flange plate 1012 and the second flange plate 1013. The upper and lower ends of the scraper 1011 are fixedly connected to the flange plates. Both the first flange plate 1012 and the second flange plate 1013 are connected to the transmission structure. The scraper 1011 is used to clean the coal slime adhering to the inner wall of the cylindrical structure. The scraper 1011 rotates in a circular motion along the circumference, and can scrape off the coal slime adhering to the inner wall of the cylinder. The movement trajectory of the scraper 1011 is slightly smaller than the circumference of the inner wall of the crusher cylinder. When rotating, it can scrape off the coal slime adhering to the inner wall. At the same time, the coal slime accumulated at the bottom of the cylinder is scraped to the discharge port by the rotating bottom cleaning frame 106, effectively ensuring the stable operation of the crusher.

The contact quantity is large and the coverage area is wide, ensuring that the coal slime adhering to the inner wall of the cylinder is removed in all directions without dead angles. This is an efficient cleaning method. Through the rotation of the scraper assembly 101, the cleaning device can effectively clean the coal slime and other adhesions on the inner wall of the cylindrical structure, keep the inside of the equipment clean, and ensure the smoothness of the crushing process. Through the continuous operation of the cleaning structure, it is possible to prevent the accumulation of coal slime and other materials in the cylinder, reduce the occurrence frequency of blockages, and improve the operation efficiency and stability of the equipment. Regularly cleaning the materials accumulated on the inner wall and bottom of the cylinder can reduce wear and corrosion, play a positive role in the maintenance of the equipment, and thus extend the service life of the equipment.
