Description

Conveying mechanism of scraper conveyor

Technical Field

The invention relates to the technical field of scraper conveyors, in particular to a conveying mechanism of a scraper conveyor.

Background

In recent years, as the production volume is increasing, the weight of the cast stone scraper conveyor is rapidly increasing and the cast stone scraper conveyor is rapidly increasing. The cast stone scraper conveyor adopts a side double-chain structure as one of key accessories, and the mechanical property and the product quality of the scraper directly influence the safety and the benefit of coal production. The slide way and the bottom of the box body of the cast stone scraper conveyor are paved by cast stones, the round-link chain and the scraper slide on the slide way when in operation, the contact parts of the two ends of the scraper and the slide way are seriously abraded, the local friction is realized, and the replacement state is reached in advance; in addition, the scraper is required to bear a large static load and transmit a large dynamic load during operation, and the scraper is also required to have a dynamic load during normal operation besides the dynamic load generated by starting or braking, wherein the former load is easy to generate strong damage, and the latter load is small but acts repeatedly for a long time and is a main cause of fatigue damage.

Therefore, the patent specification with the publication number of CN107140378B discloses a combined scraper for a cast stone scraper, which comprises an end head and a beam plate, wherein one side of the end head is provided with a T-shaped clamping groove from the upper end to the lower end, the depth of the clamping groove is less than the height of the end head, the other side of the end head is provided with a through groove penetrating through the upper end and the lower end, the middle parts of two wall plates of the through groove are provided with arc-shaped convex blocks, and the center of each arc-shaped convex block is provided with a; the both ends of beam slab are equipped with L type dop, and the dop combination back of two beam slabs cooperates with the draw-in groove, has seted up the mounting groove on the outside terminal surface of beam slab, is fixed with wear-resisting piece in the mounting groove, and the height of beam slab equals the degree of depth of draw-in groove. But the combined scraper for the cast stone scraper machine has the disadvantages of large replaced plate, resource waste and increased use cost; secondly, due to the adoption of a clamping installation mode, the disassembly is difficult.
