Return stroke blank cleaning system of belt conveyor

Abstract

The invention relates to belt conveyors, in particular to a return stroke blank cleaning system of a belt conveyor. The system comprises an intermediate rack, upper and lower carrier rollers, a head drum, an adhesive tape, first and second sweepers, third and fourth sweepers, a blank recovery device and a heavy punch type sweeper, wherein the heavy punch type sweeper comprises a counterweight supporting seat placed on one side of the intermediate rack, and a counterweight is mounted on the counterweight supporting seat; the upper end of the counterweight supporting seat is hinged to the left end of a T-shaped lever, the lower end of the lever is hinged to a lug seat of a rectangular frame, and the rectangular frame is connected to the intermediate rack through a vertical beam; the right end of the lever is hinged to the upper end of a connecting rod, the lower end of the connecting rod is hinged to the upper end of a vertical rod, the lower end of the vertical rod is connected to a cross beam below a return stroke adhesive tape through a connecting plate, the cross beam is fixedly connected to a third polyurethane scraper, and two sides of the heavy punch type sweeper are of symmetrical structures. The halt cleaning time is shortened, the labor intensity of workers is alleviated, damage of cargoes and flying dust are reduced, and service lives such as the carrier rollers, the belt and a bent roller are prolonged.

Description

technical field [0001] The invention relates to a belt conveyor, in particular to a belt conveyor return blanking cleaning system. Background technique [0002] At present, belt conveyors are suitable for conveying various granular, powdery and other bulk materials. These materials contain moisture, especially in humid environments, and their viscosity is particularly high. If the materials attached to the working surface of the conveyor belt When it is not cleaned in time, it will enter the drive roller, increase the friction on the roller, and cause damage to the conveyor belt surface rubber and the roller cover. When the tape surface attached to the material runs to the return roller, due to continuous contact, part of it will stick to the roller. When the material accumulates to a certain extent, the return roller will run out radially, which increases the load on the bearing and the axial load. , This will accelerate the wear of the roller, and sometimes cause the roll...

AI Technical Summary

Problems solved by technology

The material adheres to the idler roller, and the rotation resistance of the idler roller after freezing will increase, which will lead to increased wear of the idler roller and even wear of the tape. In severe cases, it will cause major safety accidents such as fire; Falling off, causing damage to the roller, leading to deviation of the tape, tearing the tape accident

[0004] The accumulated material spilled along the belt conveyor is cleaned manually by power-off of the belt system, which not only increases the labor intensity of workers, reduces the working efficiency of the conveyor, but is also prone to accidents
