Problems solved by technology

However, during the rotation of the ball, the scraper will produce resistance to the rotation of the ball, and after the rolling element is installed on the scraper, the impurities scraped by the scraper will be stored inside the shell, and the rolling element needs to be disassembled frequently to discharge the impurities from the opening. Otherwise, impurities will be gradually compacted in the housing, causing the balls to be stuck in the housing and difficult to rotate

Abstract

The invention belongs to the technical field of material conveying devices, and particularly relates to a scraping plate. The scraping plate comprises a scraping plate body and a rolling body, and a dirt storage cavity and a fixing hole which communicate with each other are formed in the scraping plate body; and the rolling body is mounted in the fixing hole and comprises a shell, a mounting cavity is formed in the shell, the rolling body further comprises a ball mounted in the mounting cavity, a part of the ball extends out of the lower side of the shell, and the shell is provided with a dirt discharging hole communicating with the mounting cavity and the dirt storage cavity. According to the scraping plate, impurities in the mounting cavity of the rolling body can enter and be stored in the dirt storage cavities, so that the impurities are prevented from being continuously accumulated in the mounting cavity to be compacted, the resistance of the impurities to the rotation of the ball is reduced, and the phenomenon that the balls are locked by the compacted impurities is reduced.

Description

technical field [0001] The invention relates to the technical field of material conveying devices, in particular to a scraper. Background technique [0002] A scraper conveyor is a conveying device for transporting coal and materials, usually including a chain and a scraper mounted on the chain, and the chain can drive the scraper to slide on the conveying surface of the scraper conveyor. In order to reduce the friction loss between the scraper and the conveying surface, there is a rolling body installed at the bottom of the existing scraper. The rolling body includes a shell and balls that can roll in the shell. Some of the balls protrude from the bottom side of the shell, so that they can Rolling on the surface to change the sliding friction between the scraper and the conveying surface into rolling friction, thereby reducing the running resistance of the scraper and reducing wear. [0003] However, scraper conveyors are usually used in coal mines and other environments w...
