Elastic drum cleaning device of belt-type conveyor

Abstract

The invention discloses an elastic drum cleaning device of a belt-type conveyor. The elastic drum cleaning device comprises a base, a supporting frame used for supporting a drum, and a scraping plate contacting with the surface of the drum and utilizing friction force to clean, the supporting frame is fixedly mounted on the upper side of the base, a rolling shaft is rotatably mounted on the supporting frame, the drum which freely rotates along with the rolling shaft is arranged on the rolling shaft, a step rotating shaft is rotatably mounted on the supporting frame, a rolling bearing is arranged between the step rotating shaft and the supporting frame, the scraping plate is fixedly mounted on the step rotating shaft, and a torsion spring used for tightly pressing the scraping plate on a non-working face of the drum is arranged between the scraping plate and the supporting frame. The elastic drum cleaning device has the advantages of reasonable design, freeness of rigid impact during use, long service life, simple structure, small size, light weight, convenience in mounting and demounting, low producing and using cost and convenience for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of belt conveyors, and in particular relates to an elastic cleaning device for belt conveyor rollers. Background technique [0002] At present, belt conveyors are widely used to transport granular objects such as coal, limestone, and iron ore. However, due to various reasons such as unclean unloading of materials, some materials will always stick to the tape after the tape is unloaded from the machine head. When the tape passes through the roller, it sticks to the surface of the roller, accumulates more and more, and finally causes the tape to deviate. The most commonly used method for cleaning the roller is to fix a scraping angle iron close to the roller, and scrape off the accumulated material on the roller by the angle iron, but there is a certain gap between the roller and the angle iron, and often small stones will enter it , causing damage to the drum and angle iron, greatly shortening the practical ...

AI Technical Summary

Problems solved by technology

The device needs to use a stepping motor to provide power during the working process, so that the screw nut pair drives the slider to reciprocate and linearly move back and forth, and drives the scraper installed on the scraper frame to reciprocate and linearly move back and forth on the non-working surface of the drum to realize the smoothness of the surface of the drum. Cleaning of stickies, so there are problems such as complex structure, high production cost and high operating cost
