Underground coal mine height-adjustable spraying dust falling device

Abstract

The invention discloses an underground coal mine height-adjustable spraying dust falling device. The underground coal mine height-adjustable spraying dust falling device comprises a movable mounting plate, a water storage tank and a first mounting box are correspondingly and fixedly mounted on the upper surface of the movable mounting plate, a first water pump is fixedly mounted on the inner wall of the first mounting box, a connecting pipe is fixedly connected to the water outlet end of the first water pump, the end, away from the first water pump, of the connecting pipe extends into the water storage tank, the water inlet end of the first water pump communicates with an external water source through a water pipe, and a two-way motor and a protection box are correspondingly and fixedly mounted on the upper surface of the water storage tank. According to the underground coal mine height-adjustable spraying dust falling device, by arranging the water storage tank, the two-way motor, the protection box, a vertical threaded column, an internal thread adjusting cylinder, a first bevel gear and a second bevel gear, in the actual use process of the underground coal mine height-adjustable spraying dust falling device, the two-way motor can be started according to the actual situation of an underground coal mine, so that the height of an atomizing nozzle is adjusted, and the practicability of the underground coal mine height-adjustable spraying dust falling device is improved.

Description

technical field [0001] The invention relates to the technical field of dust suppression devices, in particular to a height-adjustable spray dust suppression device for underground coal mines. Background technique [0002] During the production process of coal mines, because coal mines are usually set underground and produced in a relatively closed environment, a large amount of dust will be generated during the production process, and people working in dusty environments for a long time will seriously affect people's health. [0003] Most of the existing dust suppression devices used in underground coal mines are fixed structures, which cannot adjust their height according to the actual situation, and have poor practicability, and most of them can only spray dust in one direction, although a small part can spray dust in all directions. Spraying is carried out, but on the one hand, the distance of spraying is limited, and on the other hand, multiple atomizing nozzles need to ...

Problems solved by technology

[0002] In the production process of coal mines, because coal mines are usually set underground and produced in a relatively closed environment, a large amount of dust will be generated during the production process, and people working in dusty environments for a long time will seriously affect people's health

[0003] Most of the existing dust suppression devices used in underground coal mines are fixed structures, which cannot adjust their height according to the actual situation, and have poor practicability, and most of them can only spray dust in one direction, although a small part can spray dust in all directions. Spraying, but on the one hand, the distance of spraying is limited, on the other hand, multiple atomizing nozzles are required, resulting in a serious waste of water resources per unit time
