Abstract

The present invention relates to an elastic scraper for a conveyance belt cleaner, comprising a scraper and an elastomer arranged at the lower side of the scraper, and a positioning member arranged at the lower side of the elastomer. The elastomer comprises separated upper and lower combination parts, formed between which are a concave part and a convex part spaced therefrom. With the elastic bending and recovery property of the elastomer, the shape of the elastomer enables, in the event of collision caused when using the scraper to remove residues on the conveyance belt surface, the tip of the blade constantly and elastically abutting against the conveyance belt surface, so as to perform complete cleaning and scraping operations on the residues on the conveyance belt surface. In addition, since the blade of the scraper and the elastomer are easily assembled and disassembled, convenient replacement of the blade and the elastomer parts can also be achieved.

Description

Elastic scraper for conveyor cleaners 【0001】

The present invention relates to an elastic scraper for a conveyor belt cleaner, and more particularly to an elastic scraper structure which has good abutment elasticity and is easy to replace and replace the combined components, and is more suitable for scraping the residue on the conveyor belt.

【0002】

In the process of transporting bulk cargo such as gravel, concrete or coal mine, the conveyor belt often adheres to some residues on the surface. If these residues are not removed properly, it will affect the conveying effect of the conveyor belt and shorten the service life of the conveyor belt. . For this reason, the first cleaner is usually installed at the corner of the conveyor belt, and the second cleaner is usually installed below the conveyor belt return, with the scraper for the first and second cleaners. Abutting on the surface of the conveyor belt, it is possible to perform scraping and cleaning operations on the surface residue during the operation of the conveyor belt conveying cargo.

[0003]

Due to the poor elasticity of the scraper used in the conventional conveyor cleaner, especially the scraper for the first cleaner, the buffering effect of the buffer on the surface of the conveyor belt is often only caused by the buffering effect of the two side springs. The blade is beaten due to the strong pushing, which results in poor scraping effect, so that the residue sticks to the surface of the conveyor belt and hits the scraper, which causes the scraper to wear easily and has a gap with the surface of the conveyor belt. When the scraper wears and loses its effect, it stops replacing. The operation of the blade is difficult to replace the blade because of the positioning of the blade, which makes the replacement operation time-consuming and troublesome.

[0004]
