Abstract
The utility model discloses a kind of sanitation cart brush stepless speed regulation hydraulic system, it includes hydraulic oil container, hydraulic pump, overflow valve, operated proportional flow control valve, hydraulic motor；The inlet port of the hydraulic pump is connected with hydraulic oil container, and oil inlet, the oil inlet of operated proportional flow control valve and the oil inlet of hydraulic motor of the oil-out of hydraulic pump again respectively with overflow valve are connected；The oil-out of the oil-out of overflow valve, the oil-out of operated proportional flow control valve and hydraulic motor takes back hydraulic oil container after being connected in parallel.The sanitation cart brush stepless speed regulation hydraulic system of the structure possesses simple in construction, convenient and reliable operation, with brush function of stepless speed regulation the characteristics of.
Description
Technical field
The utility model is related to a kind of hydraulic system, particularly sanitation cart brush stepless speed regulation hydraulic system.
Background technology
At present, the brush of domestic environmental sanitation vehicles generally uses fluid motor-driven, general to set high speed, middling speed, low speed three
Individual rotating speed pattern；Two one-way throttle valves are installed in hydraulic system, by the way of bypass throttle, different apertures are adjusted to,
Change the input flow rate of motor；Hydraulic oil is set to pass through different one-way throttle valves by three-position four-way electromagnetic directional valve, it is possible to
Obtain the middling speed or lower-speed state of different rotating speeds, i.e. brush；When without one-way throttle valve, whole flows will supply horse
Reach, now as fast state.By there is corresponding button to control solenoid directional control valve to commutate on control panel in driver's cabin,
To switch the rotary regimes of brush.The defect of presence is：Brush can only work under three fixed rotating speeds, the scope of application compared with
Small, flexibility is poor, influences operating efficiency.
The content of the invention
The purpose of this utility model is to provide a kind of simple in construction, convenient and reliable operation, with brush function of stepless speed regulation
Sanitation cart brush stepless speed regulation hydraulic system, solve existing sanitation cart brush and there was only fixed several rotating speeds without stepless-adjustment
The problem of fast function effect operating efficiency.
To realize object above, the utility model sanitation cart brush stepless speed regulation hydraulic system includes hydraulic oil container, hydraulic pressure
Pump, overflow valve, operated proportional flow control valve, hydraulic motor；The inlet port of the hydraulic pump is connected with hydraulic oil container, and hydraulic pump goes out
Oil inlet, the oil inlet of operated proportional flow control valve and the oil inlet of hydraulic motor of hydraulic fluid port again respectively with overflow valve are connected；Overflow
The oil-out of the oil-out of valve, the oil-out of operated proportional flow control valve and hydraulic motor takes back hydraulic oil container after being connected in parallel.
The sanitation cart brush stepless speed regulation hydraulic system of said structure has following technical characterstic and beneficial effect：
Passing ratio flow control valve can adjust the flow of its oil-out, without being influenceed by system working pressure, with
The increase of the electric current in magnetic valve, the output flow of operated proportional flow control valve also will increase；Because operated proportional flow control valve enters
Hydraulic fluid port and motor oil inlet are connected in parallel, a part of flow can the preferential direct oil return of passing ratio flow control valve oil-out,
Remaining flow can just pass through hydraulic motor.So, just ratio can be changed by potentiometer knob on driver's cabin control panel
Electromagnetic valve current size in flow control valve, so as to can just change the input flow rate size of motor to change turning for motor in real time
Speed, realizes the stepless speed regulation of brush.In addition, the hydraulic system structure is simple and convenient to operate reliably.
Brief description of the drawings
Fig. 1 is the utility model sanitation cart brush stepless speed regulation hydraulic system structure schematic diagram.
Reference：Hydraulic oil container 1, hydraulic pump 2, overflow valve 3, operated proportional flow control valve 4, hydraulic motor 5.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model sanitation cart brush stepless speed regulation hydraulic system is made into
One step is described in detail.
As shown in figure 1, the utility model sanitation cart brush stepless speed regulation hydraulic system include hydraulic oil container 1, hydraulic pump 2,
Overflow valve 3, operated proportional flow control valve 4, hydraulic motor 5；The inlet port of the hydraulic pump 2 is connected with hydraulic oil container 1, hydraulic pump 2
Oil-out oil inlet again respectively with overflow valve 3, the oil inlet phase of the oil inlet of operated proportional flow control valve 4 and hydraulic motor 5
Even；The oil-out of the oil-out of overflow valve 3, the oil-out of operated proportional flow control valve 4 and hydraulic motor 5 takes back after being connected in parallel
Hydraulic oil container 1.
When the systems are operating normally, the output flow of hydraulic pump 2 is stable, and now proportional flow control valve 4 can adjust it
The flow of oil-out, without being influenceed by system working pressure, so a part of flow preferentially passing ratio flow valve 4 will be returned
Hydraulic oil container 1 is returned, remaining flow can just pass through hydraulic motor 5；Pass through the controllable ratio of the knob on control panel in driver's cabin
Electromagnetic valve current changes in certain scope in example flow control valve 4, it is possible thereby to make the rotating speed of hydraulic motor 5 in a model
Interior change is enclosed, that is, realizes the function of stepless speed regulation of brush.Overflow valve 3 can ensure that whole system works under suitable pressure.
