Bottom-chain-free right-angle scraper conveyor for mining

Abstract

The invention provides a bottom-chain-free right-angle scraper conveyor for mining. The scraper conveyor comprises a machine head, a tail, a scraper chain and a conveying groove, the machine head is located at one end of the conveying groove, the tail is located at the other end of the conveying groove, the scraper chain is located on the upper surface of the conveying groove, the shape of a first variable-angle middle groove is a right trapezoid, the shape of a second variable-angle conveying groove is also a right trapezoid, the right-angle side of the first variable-angle middle groove is in pin joint with one end of the second variable-angle conveying groove, the bevel edge of the first variable-angle middle groove is in pin joint with the bevel edge of the second variable-angle conveying groove, the bevel edge of the first variable-angle middle groove and the bevel edge of the second variable-angle conveying groove form an angle of 90 degrees, and the right-angle side of the second variable-angle middle groove is connected with a transition groove. According to the scraper conveyor, when a mine hole is at the angle of 90 degrees, the first variable-angle middle groove and the second variable-angle middle groove are provided at the position where turning is needed, and the first variable-angle middle groove and the second variable-angle middle groove are rotated by 90 degrees through a turning assembly, so that the scraper conveyor can be arranged.

Description

technical field [0001] The invention relates to the technical field of scraper conveyors, in particular to a bottomless chain right-angle scraper conveyor for mining. Background technique [0002] As we all know, the underground fully mechanized mining face of coal mine is the first production site of coal, and in the process of underground fully mechanized mining, the mine is often not straight and there are some angles. In the prior art, the scraper conveyor is usually straight , when the mine is at right angles, it cannot be applied. Contents of the invention [0003] In view of this, the present invention provides a bottomless chain right-angle scraper conveyor for mining to solve the technical problem that the scraper conveyor is usually straight and cannot be applied when the mine is at a right angle. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A bottomless chain right-angle scraper conveyor for mini...
