Problems solved by technology

Replacing scrapers due to loss of polyurethane coating is expensive and difficult
If it is not rare that the scraper loses its urethane covering, it is uneconomical to repair the chain and the entire chain must be replaced

Embodiment Construction

[0014] figure 1 A conveyor 10 including a chain 14 and a scraper 18 is shown in FIG. The scraper 18 comprises sound-attenuating material in the form of a polyurethane cladding 20; and a metal support 22 in the form of an embedded steel plate core, which is in figure 2 shown in . In other embodiments, other less preferred forms of metal supports, such as blocks (not shown), can be used.

[0015] More specifically, as figure 1 As shown in , the chain 14 includes two rotating links 26 connected by two side plates 30 . Although only two rotating links 26 are shown connected by two side plates 30 , the chain 14 is typically an end-to-end chain (not shown) with scrapers 18 attached at spaced locations along the chain 14 .

[0016] Two spaced-apart pins 34 extend perpendicularly to the direction of chain travel, the pins 34 extending outwardly from each side plate 30 . As explained further below, each scraper 18 is attached to spaced apart pins 34 . Such as figure 1 As shown ...

Abstract

The invention relates to a replaceable sound-absorbing conveyor chain scraper. A conveyor scraper for a chain comprising at least two spaced apart links and two side plates connecting the links, each side plate comprising two spaced apart extension pin. The scraper includes a metal support including two spaced apart cylindrical portions adapted to receive the two spaced apart extension pins. The scraper also includes a flexible housing surrounding the metal support.

Description

technical field [0001] The present invention relates to a chain scraper conveyor for conveying materials in the mining industry, and in particular to an improved design of a chain scraper conveyor. More specifically, the present invention relates to conveyor chains for continuous mining machines and chain pull units. Background technique [0002] Conveyor scrapers with various coatings have been tried in the past. The main reason for using these claddings is noise control. Although cladding has been shown to reduce conveyor noise by 5-10dBA, these materials wear out relatively quickly for scrapers and it was determined that these materials are not sufficiently commercially viable on continuous or longwall mining equipment. use value. The cladding was compressed beyond its working limit and began to crack and fall off. One cause of this failure is that the coating is too thin. There is only a finite amount of space available on the conveyor for the scraper bar, so the in...
