Description

A kind of wind sweeper for gangue belt conveyor

technical field

The utility model relates to the technical field of belt cleaning of belt conveyors, in particular to a wind cleaner for gangue belt conveyors.

Background technique

The cleaner of the existing gangue belt conveyor belt is a traditional scraper cleaner made of polyurethane board. This kind of cleaner is easy to stick to fine particle materials, and the cleaning effect is not good, resulting in a bad working environment and increasing the labor intensity of maintenance personnel. The existing cleaner directly rubs against the belt, which aggravates and speeds up the wear of the belt, reduces the service life of the belt, and is easy to stick to other sundries, causing accidental damage to the belt, such as belt tearing and scratches. And damage the belt joints, easy to tear the old belt with slight cracks, causing the belt to peel, etc., affecting production. At the same time, the residual fine particle material on the belt will easily damage the roller, shorten the service life of the roller, cause the rubber surface of the roller to wear faster, and cause the belt to slip. And the accumulation of fine particle materials under the idler roller will increase the wear of the roller and the belt, and affect the belt transportation efficiency.

Utility model content

The embodiment of the utility model provides a wind cleaner for gangue belt conveyors, which aims to solve the wear and tear on the belt and the drum of the existing cleaner, reduce the service life of the belt and the drum, reduce the transport efficiency of the belt, and be prone to accidents accidents and increase the labor intensity of maintenance personnel.

The embodiment of the utility model provides a wind cleaner for gangue belt conveyors, including a main pipe and a pressure air pipe.
