Self-propelled mine multidirectional spraying and dust falling device for coal mining

Abstract

The invention discloses a self-propelled mine multidirectional spraying and dust falling device for coal mining. The self-propelled mine multidirectional spraying and dust falling device comprises a mine body, a water storage chamber, a water injection port and a water supply mechanism. A first mounting shell is arranged on the inner side of the mine body, and a second mounting shell is arranged on the left side of the first mounting shell. Connecting anchor rods are arranged at the upper ends of the first mounting shell and the second mounting shell in a penetrating mode, the connecting anchor rods are located in the mine body, a winding shaft is arranged in the first mounting shell, and a blocking disc is embedded in the surface of the winding shaft. The self-propelled mine multidirectional spraying and dust falling device for coal mining is provided with the first mounting shell, the second mounting shell and a walking rope, the walking rope can be mounted through the first mountingshell and the second mounting shell, a follow-up device can move on the walking rope and is not affected by the ground environment at the bottom of the mine body, and follow-up walking is stable; andthe device is mounted on the upper part of the mine body, spraying and dust falling are carried out from top to bottom, and the dust falling effect is better.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a self-propelled coal mine mining multi-directional spray dust suppression device. Background technique [0002] Coal, as one of the important fuels, plays an important role in our country. At the same time, with the development of social industry, the consumption of coal is gradually increasing. During the mining process of coal mines, because there will be more dust and harmful Substances need to be subjected to dust reduction treatment before subsequent entry. At present, most of the dust reduction methods are spray dust reduction, but there are still some shortcomings in the use of existing spray dust reduction devices: [0003] 1. For example, the public number CN210239737U discloses a sprinkler and dust suppression device for underground coal mines. Aiming at the problem of excessive dust in existing mines, the following scheme is proposed, which includes a sprinkler fl...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of self-propelled coal mine mining multi-directional spray dust suppression device for mining, to solve the problem that the existing dust suppression devices on the market need to be pushed and walked in the mine when the above-mentioned background technology is used. The ground environment in the mine is relatively complex, it is difficult for the device to move smoothly, and the dust suppression effect of the device on the upper side of the mine is poor, and most of the nozzles of the existing spray dust suppression devices are fixed structures, which generally require multiple nozzles to cooperate with each other to achieve Spraying dust in different directions reduces the problem of the device's use of the nozzle
