Self-propelled compensating return stroke sweeper for conveying belt

Abstract

The invention discloses a self-propelled compensating return stroke sweeper for a conveying belt, and the self-propelled compensating return stroke sweeper for the conveying belt comprises a base, a bottom plate, a lower carrier roller seat, a sweeper framework, an upper carrier roller seat, a self-propelled compensating return stroke mechanism and an alarming mechanism, wherein the bottom plate is arranged on the base; one end of the bottom plate is bent upwards to form a limiting stop dog; the lower carrier roller seat is fixed on the bottom plate; the sweeper framework comprises a sweepingrubber eraser, an upper splint, a lower splint and a bolt; the lower splint is bent downwards to form a synchronous shifting stop dog; the upper carrier seat is positioned on the upper splint of the sweeper framework; the self-propelled compensating return stroke mechanism comprises a counterweight, a buffering spring, a hanging steel wire and a fixed pulley; the fixed pulley is fixed on the base; the buffering spring is connected with the counterweight; the other end of the buffering spring is connected with the hanging steel wire; the other end of the hanging steel wire is wound on the fixed pulley and is connected with the fixing part of the upper splint; the alarming mechanism comprises the bottom plate, a fixing bracket connected with the pivot shaft of the bottom plate, a proximity switch fixed on the fixing bracket, and an alarm connected with the proximity switch. The self-propelled compensating return stroke sweeper for the conveying belt has a self-propelled compensation function for the sweeping rubber eraser, the sweeping rubber eraser can be flexibly adjusted when the conveying belt has an uneven surface, and equal pressure is guaranteed to be applied to the surface of the running conveying belt.

Description

technical field [0001] The invention relates to a transportation machine, in particular to a self-propelled compensation conveyor belt reverse cleaning device for a belt conveyor. Background technique [0002] The mineral materials conveyed by the bulk mineral conveyor belt are often viscous when the climate is humid; such as mud, powdery materials, etc., some of which will stick to the working surface of the conveyor belt and cannot be removed during unloading, and the sticky materials will enter (Reverse travel) The lower idler roller in the empty section, dirty the idler roller and make it enter the idler body. The adverse consequences are to increase the radial load and axial load on the bearing seat, causing rapid wear of the bearing, and the surface glue of the conveyor belt will be torn and roughened by the material sticking to the idler shell, which will accelerate the wear of the conveyor belt. If the sticky matter enters the tail reversing roller, it will stick to...

AI Technical Summary

Problems solved by technology

[0004] 1. There is no automatic compensation for cleaning the rubber;

[0005] 2. The cleaning rubber is not flexible enough to adjust the elasticity of the "fluctuating" conveyor belt surface;

[0006] 3. The limit state of the cleaning rubber in the prior art cannot be predicted in time, and manual cycle inspection and monitoring are required
