A spray dust suppression device for a fully mechanized coal mining face and its working method

Abstract

The invention discloses a spraying dust suppressing device for a fully mechanized coal mining face coal mining machine and a working method of the spraying dust suppressing device. The spraying dust suppressing device comprises bases, supporting plates, a spraying mechanism and a guide rail mechanism, wherein two bases are arranged, the two bases are arranged in parallel, the tops of the two basesare slidably connected with the supporting plates, the two supporting plates are arranged in parallel, the supporting plates are slidably connected with ejecting rods, and the tops of the ejecting rods are fixedly provided with a moving plate. According to the device and the method, by means of a third servo motor, a spraying box is driven to rotate, and then rotating spraying is carried out, sothat the angle is conveniently adjusted, and the use is convenient; a fourth gear is in meshing connection with teeth, so that a first spraying pipe, a second spraying pipe and a third spraying pipe are driven to rotate to perform spraying; and the first spraying pipe, the second spraying pipe and the third spraying pipe rotate in a triangular manner, so that in the rotating spraying process, thespraying range is larger, and the dust removing effect is better.

Description

technical field [0001] The invention relates to the technical field of coal mining machines, in particular to a spray dust suppression device for coal mining machines in a fully mechanized mining face and a working method thereof. Background technique [0002] Shearer is one of the main equipment of fully mechanized mining equipment. The coal shearer evolved from the coal cutter. The coal shearer is a large complex system integrating machinery, electricity and hydraulic pressure, and the working environment is harsh. If a failure occurs, the entire coal mining work will be interrupted, resulting in huge economic losses. Shearer is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, and achieve high output, high efficiency, and low consumption. In the longwall coal mining face, the coal is broken down from the coal body by the working mechanism (broken coal)...

AI Technical Summary

Problems solved by technology

[0003] In the patent No. CN204511442U, a kind of coal mining machine external spray dust-proof device has been announced, but the spray dust-proof device also has the following defects, 1, it is not convenient to adjust the height and horizontal position of the equipment, and cannot make it wider in use , strong practicability, and simple operation; 2. The spray tube cannot be rotated, so that it cannot have the functions of wide spraying range and good dust removal effect
