Technical field
The utility model relates to a kind of hydraulic system, is specifically related to a kind of hydraulic system of concrete sprayer.
Background technique
When mine working or tunnel construction, often to use concrete sprayer, concrete sprayer is injected into tunnel lateral wall and top board with the concrete materials in the hopper, high productivity, and the resilience degree is low, and can greatly reduce the dust concentration that machine is other and nozzle is outer, eliminate the harm to workers ' health.The at present commutation of the employed concrete sprayer in colliery action is finished by mechanical device, poor reliability, and complex operation has increased workman's the amount of labour greatly, and working efficiency is very low.
The model utility content
The purpose of this utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of hydraulic system of concrete sprayer is provided, and is the all-hydraulic control system of concrete sprayer, transports steadily, simple to operate, has effectively solved the Explosion-Proof under the mine.
The utility model is the deficiency that solves the problems of the technologies described above, the technological scheme that adopts is: a kind of hydraulic system of concrete sprayer, comprise that fuel tank, plunger pump A, plunger pump B, stirring motor, turning motors, running motor, pump feed oil cylinder and tilt cylinder, also comprise agitator tank multiple directional control valve, running motor multiple directional control valve and spray tank multiple directional control valve, connect by oil pipe between the each several part;
The filler opening of plunger pump A connects fuel tank, the fuel-displaced pipeline of plunger pump A connects agitator tank multiple directional control valve and running motor multiple directional control valve successively, two selector valves of agitator tank multiple directional control valve connect respectively stirring motor and turning motors, and two selector valves of running motor multiple directional control valve connect respectively left and right running motor;
The filler opening of plunger pump B connects fuel tank, the oil outlet of plunger pump B is connected to the oil pipe between agitator tank multiple directional control valve and the running motor multiple directional control valve, also be in series with the spray tank multiple directional control valve on the fuel-displaced pipeline of plunger pump B, the oil outlet of spray tank multiple directional control valve is divided into two bye-passes, is connected to pump by hydraulicchange-over valve respectively and feeds oil cylinder and tilt cylinder;
The oil outlet of agitator tank multiple directional control valve, running motor multiple directional control valve and concrete pump multiple directional control valve is connected to fuel tank by return line.
Beneficial effect is: the hydraulic system of concrete sprayer of the present utility model, be the all-hydraulic control system of concrete sprayer, and transport steadily, simple to operate, effectively solved the Explosion-Proof under the mine.
