Description

Technical Field

[0001] The utility model relates to the technical field of coal mine equipment, in particular to a spray device for coal mines. Background Art

[0002] Coal mining mostly uses coal mining machines and multi-purpose excavators. Mechanical coal mining is highly efficient, but it also produces a lot of dust. These dusts not only pollute the environment, but also affect the health of workers and may even cause safety accidents. Therefore, the prevention and control of coal mine dust is particularly important. Spray dust removal technology is widely used in coal mine production as a simple and effective way to control dust. Water mist is sprayed into the air through a spray device, so that the suspended dust particles combine with the water mist, condense into larger particles and then settle, thereby achieving the purpose of dust reduction. In summary, the technical background of coal mine spray devices is based on the problem of coal mine dust pollution and its serious impact on the working environment and workers' health. Developed. By adopting advanced technology and optimizing manufacturing processes, modern coal mine spray devices have been able to achieve efficient and intelligent dust reduction effects, providing important safety guarantees for coal mine production.

[0034] On the basis of the first embodiment, this embodiment describes one of the implementable structures of the driving component, the driving component includes a hydraulic rod 8 symmetrically fixedly arranged on the fixed base 1, the hydraulic rod 8 is fixedly connected to the lower fixed plate 4 by a connecting plate 9, an upper limit ring 10 is fixedly arranged at the bottom of the upper fixed plate 3, a lower limit ring 11 is fixedly arranged at the top of the lower fixed plate 4, and moving grooves 12 are equidistantly provided on the upper limit ring 10 and the lower limit ring 11, the moving grooves 12 on the upper limit ring 10 and the lower limit ring 11 are relatively staggered, the moving rod 5 is movably sleeved in the upper limit ring 10 and the lower limit ring 11, and a linkage component for cooperating with the moving groove 12 to move is provided on the moving rod 5;

[0035] The linkage assembly includes a moving round block 13 fixedly and symmetrically arranged on the outer wall of the moving rod 5, a straight rod 14 fixedly arranged at the bottom of the moving rod 5, a rotating block 15 fixedly arranged on the straight rod 14, and the rotating block 15 and the moving round block 13 are made of wear-resistant and smooth materials;

[0036] In this embodiment, the hydraulic rod 8 can drive the lower fixed plate 4 to rise and fall on the support rod 2. The upper limit ring 10 and the lower limit ring 11 are movably sleeved with a moving rod 5. The moving groove 12 is arranged in an arc shape, and the upper and lower moving grooves 12 are relatively staggered. When the hydraulic rod 8 drives the lower fixed plate 4 to descend, the rotating block 15 will intermittently contact the fixed base 1 at the bottom, press the fixed base 1 downward, so that the moving rod 5 is fixed.

The same is true when rising. Because the moving grooves 12 are staggered, the moving rod 5 can be rotated in only one direction.

[0037] Embodiment three:

[0038] On the basis of the first embodiment, this embodiment describes one of the implementable structures of the rotating assembly, the rotating assembly is provided with a mounting groove 16 symmetrically on the mounting block 6, a plurality of fixed grooves 17 are provided in the mounting groove 16 at equal intervals, a water pump 18 is fixedly provided on one side of the atomizing nozzle 7, the atomizing nozzle 7 is equidistantly provided on the water pump 18, a rotating rod 19 is symmetrically provided on the water pump 18, a clamping block 20 is fixedly provided on one end of the rotating rod 19, the clamping block 20 is provided corresponding to the fixed groove 17, the rotating rod 19 is provided corresponding to the mounting groove 16, and an adjusting rod 21 is fixedly provided on one side of the rotating rod 19;

[0042] Working principle: When spraying operation is required in the coal mine, the operator turns on the water pump 18, and the atomizing nozzle 7 can spray water mist on one side. The upper and lower angles of the atomizing nozzle 7 can be adjusted by rotating the adjusting rod 21;

[0043] When automatic spraying is required, the hydraulic rod 8 is controlled to perform timed reciprocating extension and retraction. When the hydraulic rod 8 drives the lower fixed plate 4 to descend, the rotating block 15 will intermittently contact the fixed base 1 at the bottom, pressing down the fixed base 1, so that the moving rod 5 is fixed.

The same is true when rising. Because the moving grooves 12 are staggered, the moving rod 5 can be rotated in only one direction, thereby realizing the fully automatic lifting and rotating spraying of the atomizing nozzle 7, and improving the spraying range and effect.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
