Mining equipment and spraying system thereof

Abstract

The invention discloses a spraying system used for mining equipment, comprising a joint component (21) installed in the transmission cavity of the mining equipment, wherein the joint component is provided with an effluent path (22), one end of the effluent path (22) is communicated with the outer part of the transmission cavity, and the other end of the effluent part is communicated with a water inlet path (23) communicated with a water source; sealed components (24) are installed between the water inlet path and the transmission cavity; at least two sealed components are arranged along the axial direction of the joint component; and an isolated component (25) communicated with the outside of the transmission cavity is arranged between the two sealed components. When at least one of the two sealed components fails, water penetrates out of the transmission cavity by the isolated component so as to perform the early warning function for the failed sealed component. When the sealed component is damaged, the damaged component can be observed from outside so as to protect the transmission cavity when the sealed component fails. The invention also discloses mining equipment comprising the spraying system.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a spray system for coal mining equipment. The present invention also relates to a coal mining equipment comprising the above-mentioned spraying system. Background technique [0002] With the rapid development of my country's economic construction, the coal industry continues to develop in the direction of mechanization and automation, and comprehensive mechanized coal mining equipment is more and more widely used in coal production under various geological conditions. [0003] Coal mining equipment will generate a large amount of dust during the coal mining process, and with the continuous increase of the power of the coal mining machine, although the stepping speed of the coal mining face has been significantly increased, it has also resulted in a large increase in dust. In coal mine production, the dust production of the fully mechanized mining face is very large, acc...

AI Technical Summary

Problems solved by technology

[0006] But because in the working process of coal mining equipment, sealing ring 15 may be damaged, when sealing ring 15 is damaged, high-pressure water will enter in the transmission cavity of coal mining equipment, and because the sealing ring 15 cannot be observed outside the coal mining equipment Whether the ring 15 is damaged, often when the sealing ring 15 is found to be damaged, a large amount of water has entered the multiple transmission chambers of the coal mining equipment, which not only affects the effect of spraying and dust removal, but also causes the mechanism in the transmission chamber to fail to work normally due to water ingress , which seriously affects the working performance of coal mining equipment
