Description

Technical Field

[0001] The present application belongs to the technical field of coal mining spraying, and in particular relates to a spraying device for coal mining equipment. Background Art

[0002] Coal mining machine is one of the important equipment for realizing the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, and achieve the goals of high output, high efficiency and low consumption. However, a large amount of smoke will be generated in the process of coal mining and transportation. At this time, a spray device is needed to reduce the dust.

[0003] The existing utility model with authorization announcement number CN217300573U discloses an external spray device for a coal mining machine, including a coal mining machine, with a first spray module and a second spray module respectively arranged on both sides of the coal mining machine. The first spray module includes a first steel plate welded to the outer surface of the coal mining machine, the first steel plate is hollow, and multiple groups of first spray components are evenly distributed therein, and the first spray component is connected to a first drive component that drives it to operate; the second spray module includes a second steel plate welded to the outer surface of the coal mining machine, the second steel plate is hollow, and multiple groups of second spray components are evenly distributed therein, and the second spray component is connected to a second drive component that drives it to operate.

[0004] With the above technical solution, when the first nozzle and the second nozzle spray liquid outward, the rotating nozzle rotates and sprinkles the spray, and the spray is sprayed outward under force, and the diffusion radius is large, which increases the area of ​​the spray floating in the air, increases its contact area with the dust, and enhances the effect of atomization and dust reduction. However, the above technical solution installs the spray equipment inside the coal mining machine, but it is not convenient for maintenance. Once a problem occurs, it is difficult to repair quickly. In addition, it is easy to adjust the spray angle when installed inside the coal mining machine, and the spray can only be carried out according to the angle of the coal mining machine. If it is too close to the coal mine, a large amount of dust can easily block the nozzle outlet.

[0005] Therefore, we propose a spray device for coal mining equipment to solve the above problems. Utility Model Content
