Abstract
The utility model discloses an integrated coal mining inter-support spray device, comprising a support and its hydraulic transmission gear. The hydraulic transmission gear is provided with a quick-moving maneuvering valve and a quick-moving hydraulic oil cylinder, and several spray rods mounted on the support. Each spray rod is provided with several nozzles, the quick-moving maneuvering valve is also connected to a hydraulically controlled water valve, which is connected in parallel with the quick-moving hydraulic oil cylinder in the hydraulic transmission gear and communicated with the spray rods and a water pump via a spray pipe respectively. The utility model is characterized in that since the hydraulically controlled water valve and the quick-moving hydraulic oil cylinder are connected in parallel in the hydraulic transmission gear, the high pressure during the operation of the hydraulic support is used to drive the hydraulically controlled water valve, realizing automatic spray settling and inter-support combined spraying settling when the hydraulic support of the integrated mining working surface in a coal mine opens the window to discharge coal, reducing the dust concentration. The utility model is of simple structure, ease of use, excellent environmental friendship and easy application.
Description
Technical field
The utility model relates to winning equipment, atomization mechanism between particularly a kind of performing comprehensive coal mining frame.
Background technology
At present, in the mining of fully-mechanized mining working, the environmental protection condition of operating environment is still relatively poor under coal mine, window when putting coal at hydraulic support, and the dust concentration height, the workman is healthy to be subjected to very big influence, also has influence on and combines the safety of adopting.Simple in structure now, dependable performance, the practical ideal product that is used for the coal-face depositing dust also lacks very much.
The utility model content
The purpose of this utility model provides and a kind ofly can reduce atomization mechanism between good, simple in structure, the easy to use performing comprehensive coal mining frame of operating environment dust concentration, environment protecting.
For achieving the above object, atomization mechanism between the utility model performing comprehensive coal mining frame, comprise support and hydraulic transmission thereof, hydraulic transmission is provided with and moves the frame control valve and move the frame hydraulic jack, also comprise rack-mount some spray booms, each spray boom is provided with plurality of nozzles, moves the frame control valve and also links to each other with a hydraulic control water valve, the hydraulic control water valve with move the frame hydraulic jack and be connected in the hydraulic transmission, and be interconnected respectively by jet pipe and spray boom and water pump.
Atomization mechanism between the utility model performing comprehensive coal mining frame, the wherein said frame control valve that moves is a three-position valve, wherein is provided with the operation gear that is used for " moving the frame spraying " and " stopping ".
The advantage of atomization mechanism is between the utility model performing comprehensive coal mining frame: since the hydraulic control water valve with move the frame hydraulic jack and be connected in the hydraulic transmission, high pressure when utilizing the hydraulic support operation is as power, drive the hydraulic control water valve, can the auto spraying depositing dust when fully-mechanized mining working surface hydraulic support is windowed and put coal under coal mine and and frame between connection spray depositing dust, reduced dust concentration, it is simple in structure, easy to use, environment protecting is good, helps promoting the use of.
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, deep understanding arranged with purpose, feature and advantage to atomization mechanism between the utility model performing comprehensive coal mining frame.
Description of drawings
Fig. 1 is the schematic diagram of atomization mechanism between the utility model performing comprehensive coal mining frame.
The specific embodiment
With reference to Fig. 1, atomization mechanism comprises support and hydraulic transmission thereof between the utility model performing comprehensive coal mining frame, hydraulic transmission is provided with and moves frame control valve 1, moves frame hydraulic jack 7 and hydraulic control water valve 2, hydraulic control water valve 2 with move frame hydraulic jack 7 and be connected in the hydraulic transmission.A plurality of spray booms 3 are housed on the support, and each spray boom 3 is provided with a plurality of nozzles 4.Hydraulic control water valve 2 is interconnected respectively by jet pipe 6 and spray boom 3 and water pump 5.Move frame control valve 1 and be three-position valve, wherein be provided with the operation gear that is used for " moving the frame spraying " and " stopping ".
Use atomization mechanism between the utility model performing comprehensive coal mining frame, be high pressure when utilizing the hydraulic support operation as power, drive hydraulic control water valve 2, with the break-make water source and with support synchronous operation, spraying is opened when promptly moving frame, moves frame and finishes, spraying stops.When moving frame control valve 1 and place on " move frame spraying " gear, hydraulic transmission drives simultaneously and moves frame hydraulic jack 7 and hydraulic support is windowed put coal and hydraulic control water valve 2 is opened, and water pump 5 is sprayed by hydraulic control water valve 2 to spray boom 3 and each nozzle 4.When on the gear that places " stopping ", move frame hydraulic jack 7 hydraulic support is stopped, hydraulic control water valve 2 cuts out, spraying stops.Like this, can join the spray depositing dust when fully-mechanized mining working surface hydraulic support is windowed and put coal under coal mine, reduce dust concentration, improve the operating environment of coal-face.
Atomization mechanism can be formed different series according to rack form is different between the performing comprehensive coal mining frame, and apparatus structure is simple, and dependable performance is practical, is the ideal product of colliery depositing dust, helps promoting the use of.
