Efficient scraper conveyer with chain jumping prevention function

Abstract

The invention relates to an efficient scraper conveyor with a chain jumping prevention function. The efficient scraper conveyor comprises a power device, a machine groove, a chain and two driving chain wheels, further comprises a supporting mechanism and at least two coal scraping mechanisms; the supporting mechanism comprises a first sliding rod, a reinforcing sleeve, a lifting rod, a supporting chain wheel, two mounting plates and two power assemblies, and each coal scraping mechanism comprises a mounting seat, a second transmission rod, a scraper, a second sliding rod, a second spring and a movable sleeve pipe. According to the efficient scraper conveyor with the chain jumping prevention function, the chain is in a tightening state through the supporting effect of the supporting mechanism on the chain, the pressure between the chain and a driving chain wheel is increased, the probability of chain jumping between the chain and the driving chain wheel is reduced, the practicability of the scraper conveyer is improved, the passing rate of the coal briquettes between the coal scraping mechanism and the inner wall of the machine groove is reduced through the coal scraping mechanism, the coal scraping effect of the coal scraping mechanism is improved, and the conveying efficiency of the scraper conveyer is improved.

Description

technical field [0001] The invention relates to the field of coal mining equipment, in particular to a high-efficiency scraper conveyor with the function of preventing chain skipping. Background technique [0002] The scraper conveyor is pulled by a scraper chain, and the conveyor that transports bulk materials in the groove is called a scraper conveyor. The adjacent middle trough of the KS scraper conveyor can be flexed to a limited extent in the horizontal and vertical planes, which is called a bendable scraper conveyor. Among them, the working face conveyor whose fuselage is bent at 90 degrees at the intersection of the working face and the transportation roadway is called "corner scraper conveyor". In the current coal mining face, the role of the scraper conveyor is not only to transport coal and materials, but also the running track of the coal mining machine, so it has become an indispensable main equipment in the modern coal mining process. [0003] In the process o...

Problems solved by technology

[0003] In the process of using the scraper conveyor in the prior art, the chain is subjected to relatively large resistance, which causes chain skipping between the chain and the sprocket, which reduces the practicability of the scraper conveyor. Not only that, the prior art During the use of the scraper conveyor, the scraper pushes the coal to move along the machine groove. During this process, the scraper is prone to tilt, causing the coal to pass under the scraper, which reduces the scraper conveyor. transmission efficiency
