Abstract
The utility model provides a coal miner rocker arm external spray device, which comprises a closed box. Three nozzles are welded to the front side of the box in a communication manner, a high-pressure air hose joint and a high-pressure water hose joint are welded to the rear side of the box, and a magnet is attached to the lower side of the box. When in work, dustproof water in a dustproof pipe is accessed through the high-pressure water hose joint, pressure air in a pressure air pipe is communicated via the high-pressure air hose joint, the pressure air and the dustproof water enter the box at the same time, the dustproof water is sprayed out through the three nozzles in a mist manner under power of the pressure air, and the ideal effect of unit external spray under lower water pressure conditions is realized.
Description
Technical field
The utility model relates to the synthesis dust prevention device for reducing dust of comprehensive mechanical coal mining machine.
Background technology
Present coal-winning machine all is being equipped with the unit internal spraying and attached to 3 shower nozzle external spraying devices on the coal machine rocking arm on the coal-winning machine when dispatching from the factory.Its operating principle is: be utilized as the dustproof pipeline of coal-face service or atomizing pump pipeline and provide pressure and dustproof water for unit inner sprayer unit and external spraying device, by hydraulic pressure water is formed through shower nozzle vaporific, thereby reach depositing dust, catch the purpose of dirt.But owing to be subjected to the down-hole influence of hydraulic pressure, it is vaporific to be difficult to formation, and result of use is very undesirable.
Summary of the invention
At the deficiency of above-mentioned technology, the utility model provides a kind of rocker arm of coal mining machine external spraying device of pressing wind to mix with water that utilizes.
The technical scheme that the utility model is taked is: it comprises the box body of a sealing, the welding of box body dead ahead is communicated with three shower nozzles, be welded to connect a high-pressure blast hose coupling and a high-pressure water hose joint in the box body dead astern, magnet of box body attached below so that with the rocker arm of coal mining machine adhesive.
The utility model has the advantages that: during work, dustproof water in the dustproof pipe is communicated with by the high-pressure water hose joint, pressure wind in the pressure ventilation pipe is communicated with by the high-pressure blast hose coupling, press wind and dustproof water to enter in the box body simultaneously, dustproof water is under the power of pressing wind, by three vaporific ejections of shower nozzle, realized the desirable effect of unit external spraying under lower hydraulic condition.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Marginal data: 1-φ 10mm high-pressure water hose joint; 2-φ 19mm high-pressure blast hose coupling; The 3-box body; 4-φ 10mm shower nozzle; 5-magnet.
The specific embodiment
As shown in Figure 1, the utility model embodiment is that welding is communicated with three φ 10mm shower nozzles 4 in box body 3 dead aheads, be welded to connect a φ 19mm high-pressure blast hose coupling 2 and a φ 10mm high-pressure water hose joint 1 in box body 3 dead asterns, magnet 5 of box body 3 attached below is so that shake the wall adhesive with coal-winning machine.
