Description

External spraying block assembly for rocker arm of coal mining machine

Technical Field

The utility model relates to the technical field of coal mining machines, in particular to an outer spraying block assembly of a rocker arm of a coal mining machine.

Background

The coal mining machine is a large complex system integrating machinery, electricity and hydraulic pressure, the working environment is severe, if a fault occurs, the whole coal mining work can be interrupted, and huge economic loss is caused.

Can set up the spraying subassembly on the current coal-winning machine and spray water smoke in order to reach the purpose of dust fall, and because the spraying subassembly is independent direction mostly, lead to carrying out the during operation in the pit, owing to do not have a large amount of circulation of air, the spraying that leads to independent direction can not play fine dust fall effect, has caused the puzzlement to going on of staff's coal mining work.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects in the prior art and provides an outer spray block assembly of a rocker arm of a coal mining machine.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a coal-winning machine rocking arm outer spraying block group spare, includes outer atomizer and inlet tube, the water course has been seted up to outer atomizer inner wall, evenly be equipped with a plurality of nozzles on the water course inner wall, the nozzle is equipped with the packing ring with the water course junction, water course tip fixedly connected with sprue, outer atomizer both sides are equipped with the mounting, outer atomizer bottom is equipped with the water inlet with inlet tube looks adaptation, the inlet tube tip is equipped with sealing mechanism.

Preferably, the fixing piece comprises a threaded nail in threaded connection with the inner wall of the outer sprayer, and the outer sprayer is connected with the coal mining machine through the threaded nail.

Preferably, the sealing mechanism comprises two sealing nuts in threaded connection with the outer side wall of the water inlet pipe, and a rubber sealing semi-ring is arranged at the end part of each sealing nut and matched with the water inlet.

Compared with the prior art, the utility model has the beneficial effects that:

1. the nozzles with a large number are concentrated on one outer sprayer, the water spraying effect is good, the water spraying direction is divided into three directions, the underground dust falling effect can be greatly achieved, and the trouble caused by coal mining work of workers is avoided.

2. Through setting up sealing mechanism for when advancing water inlet and water piping connection, through screwing up gland nut, alright press from both sides tight water inlet with two rubber seal semi-rings, thereby seal water inlet and inlet tube junction, avoid producing the gap because high-pressure rivers's reason in the course of the work.
