Description

Technical Field

[0001] The utility model relates to the technical field of coal mine dust reduction equipment, in particular to a roadway sprinkler atomizing dust reduction vehicle for underground coal mines. Background Technique

[0002] During the production process in underground coal mines, a large amount of dust will be generated. When miners work in an environment full of dust, on the one hand, safety accidents may be induced due to the greatly reduced vision, and on the other hand, the risk of miners suffering from pneumoconiosis will also be increased. For a long time, high-pressure spraying has been mainly used in underground mines to achieve the purpose of dust reduction. The high-pressure spraying is installed on the circumference of the underground roadway, at a certain distance from the working face and extends forward as the working face advances. However, the frequent installation and disassembly of the spraying rack not only takes time and effort, but also the high-altitude operation required during the installation process will cause greater safety hazards. In addition, due to the close distance between the spraying rack and the working face, during the blasting process in the underground tunneling working face, the spraying rack is easily damaged by the blasting flying stones, which increases the maintenance cost of the spraying rack and also affects the dust reduction efficiency.

[0003] For example, a movable spraying dust reduction device for underground coal mines with the publication number CN205117391U is used to solve the problem that the moving range of the spraying dust reduction device is limited due to the dependence on the underground laid water pipes. The device consists of a pump, a spraying rack and a water tank that moves with the spraying rack. The water tank is detachably installed on the trolley and can be conveniently moved along the underground track according to the needs of the working face. With multiple backup water tanks for replacement, the problem that the working range of the prior art is limited by the underground water pipes is solved, and dust reduction operations can be carried out on the working face without underground water pipes laid. At the same time, the water tank that can move flexibly with the spraying rack also reduces the time required for the frequent installation and disassembly of the spraying dust reduction device, and solves the problems of untimely dust reduction and low dust reduction efficiency caused by the installation and disassembly of the connecting pipelines.

[0004] The above technical solution has some problems in practical applications. The dust reduction range in underground coal mines is limited during the use of this technical solution, and it is difficult to achieve large-area dust reduction and cleaning.

[0005] Therefore, it is very necessary to invent a roadway sprinkler atomizing dust reduction vehicle for underground coal mines to solve the above problems. Content of the Utility Model
