Embodiment 1

[0016] Such as figure 1 As shown, a roadheader airborne spray power system includes a roadheader 1, a water pump 2 and an atomizer 3, the hydraulic system 5 of the roadheader 1 is connected to the high-pressure oil inlet 6 of the water pump 2, and the roadheader The hydraulic system 5 of 1 drives the high-pressure pump to work through the reciprocating motion of the plunger, converts the low-pressure water supplied to the high-pressure pump into high-pressure water, and then passes through the matching atomizer 3, which is atomized by the atomizer 3 into a high-speed atomized flow and sprayed to the dust. source to achieve effective control of dust.

[0017] Preferably, the outlet of the water pump 2 is connected to the atomizer 3, and the atomizer 3 is connected to a plurality of spray heads.

[0018] The water pump uses the piston of the hydraulic oil cylinder to push the piston of the high-pressure water pump to reciprocate, so high water pressure can be generated without ...

Embodiment 2

[0020] Such as figure 2 As shown, on the basis of Embodiment 1, the water suction port 7 of the water pump 2 is connected to the cooling water outlet 8 of the roadheader 1; the water pump 2 adopts positive pressure water supply and is directly installed at a reasonable position on the body of the roadheader 1 The water pump 2 supplies water from the cooling outlet of the roadheader 1; the cooling water outlet 8 of the roadheader 1 is provided with a filter 4.

[0021] The water consumption of this device is correspondingly reduced, and the water inlet filter equipped with the spray system can ensure the filtration of spray water and prevent impurities from entering the high-pressure pump and spray system; compared with ordinary water pumps, the output water pressure of this device can be adjusted by a pressure regulating valve or It is directly adjusted by the input power of the hydraulic system. The small and compact appearance of the water pump can be easily installed on an...

Abstract

The invention provides an airborne spray power system of a roadheader, which relates to the field of water pumps, including a roadheader, a water pump and an atomizer, the hydraulic system of the roadheader is connected to the high-pressure oil inlet of the water pump, and the hydraulic system of the roadheader The high-pressure pump is driven by the reciprocating motion of the plunger, and the low-pressure water supplied to the high-pressure pump is converted into high-pressure water, and then passed through the matching atomizer, which is atomized into a high-speed atomized flow and sprayed to the dust source to achieve effective dust removal. Control; the invention uses the hydraulic cylinder piston to push the high-pressure water pump piston to reciprocate, so high water pressure can be generated without rotating parts, the atomization effect is good, and the water consumption is correspondingly reduced. Compared with ordinary water pumps, the output water pressure can be used The pressure regulating valve can be adjusted directly by the input power of the hydraulic system. The small and compact appearance structure of the water pump can be easily installed on any load-bearing machinery.

Description

technical field [0001] The invention relates to the field of water pumps, in particular to an airborne spray pump of a roadheader. Background technique [0002] Dust exceeding the standard in coal mines is one of the main hazards, which can cause safety accidents such as explosions, and is also the cause of pneumoconiosis. The nozzle is arranged next to the pick on the cutting head. When cutting coal and rock, it rotates with the cutting head and sprays water mist to realize the functions of dust reduction, cooling and spark extinguishing. [0003] However, at present, internal spraying is often not used as the most effective means of dust reduction in excavation work. The main reason is that the existing spraying device is too waste water and the atomization effect is not good. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides an airborne spray pump of the roadheader, which has good atomization effect and corre...
