Conveying belt sweeping device

Abstract

The invention discloses a conveying belt sweeping device. The conveying belt sweeping device comprises a fixing frame and a scraping plate, wherein the fixing frame is composed of a left support, a right support and a connecting plate for connecting the left support and the right support together; and the left support and the right support are sleeved with sleeves fixedly connected to the two ends of the connecting plate; and the sleeves are connected with the left support and the right support in a sliding mode. The scraping plate is fixedly connected to the connecting plate, the part, below the corresponding sleeve, of the left support is sleeved with a spring; the part, below the corresponding sleeve, of the right support is sleeved with a spring; and adjusting screw caps are connected with the lower end of the part, below the corresponding spring, of the left support and the lower end of the part, below the corresponding spring, of the right support in a screw joint mode. The scraping plate is arranged between the connecting plate and a clamping plate, and the clamping plate and the scraping plate are fixed to the connecting plate through screws. Friction force between the scraping plate and a conveying belt can be adjusted through adjusting bolts. By the utilization of elasticity of the old conveying belt and elasticity of the springs, the friction force between the scraping plate and the conveying belt can be automatically adjusted, in this way, abrasion to the belt can be effectively reduced, the sweeping effect can be improved, and the service life of the conveying belt is prolonged.

Description

technical field [0001] The invention relates to the technical field of conveying equipment, in particular to a conveyor belt cleaner. Background technique [0002] When the belt conveyor is running, the conveyor belt cleaner is installed on the back side of the return conveyor belt, close to the head, the roller at the tail of the machine or the vertical tension device to the roller, mainly used to clean the coal slime and coal dust on the conveyor belt , to prevent it from being brought into the tail drum. At present, underground raw coal transportation is mainly carried by belt conveyors. Each belt conveyor needs to be equipped with a belt cleaner. The triangular friction belt cleaner is currently used. Because of the large friction between the conveyor belt cleaner and the conveyor belt, it is difficult to The wear of the conveyor belt is relatively serious, which reduces the life of the belt, and the cleaning effect is not good, requiring workers to frequently clean the...

Problems solved by technology

At present, underground raw coal transportation is mainly carried by belt conveyors. Each belt conveyor needs to be equipped with a belt cleaner. The triangular friction belt cleaner is currently used. Because of the large friction between the conveyor belt cleaner and the conveyor belt, it is difficult to The wear of the conveyor belt is relatively serious, which reduces the life of the belt, and the cleaning effect is not good, requiring workers to clean the slime on the conveyor belt frequently

Now there are many kinds of cleaners on the market, such as: electric cleaners, brush cleaners, and rolling cleaners, which have disadvantages to varying degrees: poor practicability, good environment requirements, high precision requirements, and high investment funds.

[0003] Although the standard belt conveyor is equipped with a cleaner, the cleaning effect is not satisfactory due to the relatively high water content in the coal. The belt sticks to the slime more seriously, and the belt is prone to deviation.
