Sweeper with rubber torsion spring alloy for conveyor belt

Abstract

The invention discloses a sweeper with rubber torsion spring alloy for a conveyor belt. The sweeper comprises a fixing and adjusting assembly, a scraper frame and scraper units, wherein the fixing andadjusting assembly is mounted on conveyor belt intermediate frame channel steel; the two ends of the scraper frame are mounted on the fixing and adjusting assembly; the scraper frame comprises a scraper rod, a long shaft sleeve and a short shaft sleeve; the long shaft sleeve and the short shaft sleeve are perpendicular to the direction of an axial line of the scraper rod and are alternately arranged on the same plane of the same side of the scraper rod; and the scraper units are arranged on one side of the scraper rod in a staggering and overlapping manner. According to the sweeper with the rubber torsion spring alloy for the conveyor belt disclosed by the invention, the scraper driven by adopting rubber torsion spring elastic elements has excellent dynamic compensation performance, the scraper has better tracking performance on a conveyor belt, and materials are difficultly squeezed into the scraper and an adhesive belt so that materials are difficultly accumulated on a cutter head;the top surface of the scraper contact the belt, so that equal contact force of the scraper and the belt is realized, material scraping from all scraper surfaces can be realized, and the service lifeis longer; the scraper units are arranged through adoption of vertical scraper rods and the parallel surface of the adhesive belt, and therefore, the sweeper can be used in narrow and small mounting positions, and the application range is wider.

Description

technical field [0001] The invention relates to the technical field of belt conveying in power stations, ports, mines, etc., in particular to a conveyor belt rubber torsion spring alloy cleaner, which is used for cleaning high-viscosity and easy-to-stick coal slime, ore slime, foreign matter, etc. on the conveyor belt. Background technique [0002] Belt conveyor is the main way to transport bulk materials in power stations, ports, mines and other industries, and the conveyor belt is the most widely used conveying device in the process of material transportation and transshipment. [0003] The traditional cleaner scraper is made of elastic polyurethane. The scraper is prone to frictional heat and internal heat during the cleaning process, which affects the hardness of the polyurethane elastomer. When the hardness of the scraper is reduced, the high-viscosity and sticky material particles will penetrate into the conveyor belt and the scraper In the middle, the scraper is separ...

AI Technical Summary

Problems solved by technology

[0003] The traditional cleaner scraper is made of elastic polyurethane. The scraper is prone to frictional heat and internal heat during the cleaning process, which affects the hardness of the polyurethane elastomer. When the hardness of the scraper is reduced, the high-viscosity and sticky material particles will penetrate into the conveyor belt and the scraper In the middle, the scraper is separated from the conveyor belt, and the material stuck on the conveyor belt cannot be effectively removed. The sticky material layer will cause material accumulation on the roller and idler roller, the roller is not round, the belt is slipping, and the capacity cannot meet the design requirements

When the belt is dry, as the belt runs, the viscous material layer falls off in fragments, making it difficult to scatter and clean the conveyor belt along the way.

At the same time, the scraper of the traditional cleaner is worn out. In order to ensure the life of the scraper, the scraper has a large volume, and it is often impossible to install and use the cleaner due to insufficient space for installation.
