Problems solved by technology
[0003] In order to solve the above technical problems, this application provides a rolling element with good sealing performance. Under the sealing effect of the wear-resistant ring, impurities are not easy to enter the installation cavity, and the impurities that enter the installation cavity can be stored in the dirt storage cavity. , and discharged to the outside through the sewage outlet and sewage hole, thereby preventing impurities from accumulating in the installation cavity, reducing the phenomenon that the ball is stuck in the installation cavity and making it difficult to rotate, improving the rolling performance of the ball, and effectively solving the existing problems in the prior art. The problem

The invention relates to the technical field of material conveying, in particular to a rolling body with good sealing performance, which comprises a shell, a ball and an elastic sealing piece. A mounting hole is formed in the bottom wall of the mounting cavity; the balls are mounted in the mounting cavities and partially extend out of the mounting holes; the elastic sealing piece comprises a wear-resisting ring, the wear-resisting ring is installed in the installation cavity and abuts against the outer surface of the ball, a dirt storage cavity is formed between the inner side of the wear-resisting ring and the outer side of the ball, a dirt outlet communicated with the dirt storage cavity is formed in the cavity wall of the dirt storage cavity, and a dirt discharging hole communicated with the dirt outlet is formed in the bottom wall of the installation cavity. Under the sealing effect of the wear-resisting ring, impurities are not prone to entering the mounting cavity, and the impurities entering the mounting cavity can be stored in the dirt storage cavity and discharged to the outside through the dirt outlet hole and the dirt discharging hole, so that the impurities are prevented from being accumulated in the mounting cavity, the phenomenon that the ball is clamped in the mounting cavity and is difficult to rotate is reduced, and the rolling performance of the ball is improved.
Description
technical field [0001] The present application relates to the technical field of material conveying, and in particular, to a rolling body with good sealing performance. Background technique [0002] The applicant has developed a rolling body, which includes a casing and balls, the casing has an installation cavity inside, the balls are installed in the installation cavity, and the balls partially protrude from the bottom side of the casing and can roll in the installation cavity. The rolling element can be applied to material conveying devices, for example, the rolling element can be applied to scraper conveyor, scraper conveyor is a conveying device for conveying coal and materials, usually including a chain and a scraper mounted on the chain, the chain can Drive the scraper to move along the chute, and the rolling elements can be installed at the bottom of the scraper to reduce the running resistance of the scraper. However, scraper conveyors are usually used in scenes wi...
