Description
Technical field
The utility model relates to a kind of environmental sanitation refuse collector, particularly relates to rubbish container push pedal hydraulic efficiency pressure system.
Background technology
At present, the compression of the rubbish in the known hydraulic garbage case is driven by multistage hydraulic cylinder and realizes.
The patent No. is the hydraulically buried rubbish container of CN200620097663.0, is made up of rubbish casing, connecting rod mechanism, hydraulic efficiency pressure system, electric control system and underground hole groove.Hydraulic efficiency pressure system is the double pump open circuit, one of them oil pump links by oil pipe and solenoid directional control valve, push pedal oil cylinder, another oil pump also links with hoist cylinder, door opening or closing oil cylinder and chamber door locking cylinder respectively by three solenoid directional control valves of oil pipe and other are in parallel, the push pedal oil cylinder is a multi-stage oil cylinder, and the effect of push pedal oil cylinder is to provide propulsive effort for the rubbish compression.
When compressed garbage, the rodless cavity oil-feed rod chamber oil return of multi-stage oil cylinder, otherwise, when push pedal is return, the oil return of rod chamber oil-feed rodless cavity, at this moment, the annulus area of oil suction chamber has only oil-out area 1/8th, that is to say, 8 times of flow oil sump tanks that are equivalent to oil inlet quantity are arranged when push pedal is return, at this moment, not only flow is big and pressure is high oil return just to occur, and return oil system does not satisfy the speed of oil return, and speed is extremely slow or creep when push pedal just occurring and returning, and puncture the oil return filter screen easily, and increased the operation pressure when returning.
Summary of the invention
The purpose of this utility model provides a kind of rubbish container push pedal hydraulic efficiency pressure system, and this hydraulic efficiency pressure system is moved smooth and easy when push pedal is return, and speed is fast, no creeping phenomenon.
In order to achieve the above object, rubbish container push pedal hydraulic efficiency pressure system of the present utility model comprises multi-stage oil cylinder, Hydraulic Pump, change-over valve and fuel tank, it is characterized in that: also comprise hydraulic control one-way valve;
Hydraulic Pump connects with change-over valve by oil pipe, change-over valve connects with multi-stage oil cylinder by oil pipe, the rodless cavity of multi-stage oil cylinder connects with hydraulic control one-way valve, the control end of hydraulic control one-way valve connects with the rod chamber of multi-stage oil cylinder, the oil inlet end of Hydraulic Pump is connected with oil filter, the oil filter oil inlet end connects with fuel tank, and hydraulic control one-way valve and change-over valve connect with fuel tank by oil pipe.
Between the oil outlet end of Hydraulic Pump and fuel tank by pass valve is installed, the effect of by pass valve is to guarantee that hydraulic system working pressure is no more than the pressure of setting.
Oil outlet end at Hydraulic Pump also is equipped with oil pressure indicator, is used for showing the operation pressure of hydraulic efficiency pressure system.
When compressed garbage, hydraulic pump works makes hydraulic oil enter the rodless cavity of multi-stage oil cylinder from change-over valve, and the hydraulic oil in the rod chamber of multi-stage oil cylinder directly flows back to fuel tank through change-over valve, because at this moment the pressure of rod chamber is very low, hydraulic control one-way valve can not be opened; When push pedal is return, hydraulic pump works makes hydraulic oil enter the rod chamber of multi-stage oil cylinder from change-over valve, at this moment the pressure of rod chamber is exactly the operation pressure of hydraulic efficiency pressure system, under the effect of operation pressure, hydraulic control one-way valve just is opened, hydraulic oil in the rodless cavity of multi-stage oil cylinder flows back to fuel tank through hydraulic control one-way valve, make the pressure in the rodless cavity very low, multi-stage oil cylinder with regard to smooth and easy, rapidly the push pedal that is installed on it is return, and, because the spill pressure of system is low, has also guaranteed the safe and reliable to operation of system.
Rubbish container push pedal hydraulic efficiency pressure system of the present utility model, smooth and easy when push pedal is return, speed is fast, and no creeping phenomenon is safe and reliable.
Description of drawings
Fig. 1 is the system schematic of the utility model embodiment.
The specific embodiment
Fig. 1 description of symbols: Hydraulic Pump 1, multi-stage oil cylinder 2, change-over valve 3, hydraulic control one-way valve 4, fuel tank 5, by pass valve 6, oil filter 7, oil pressure indicator 8.
Referring to Fig. 1, rubbish container push pedal hydraulic efficiency pressure system of the present utility model mainly is made up of multi-stage oil cylinder 2, Hydraulic Pump 1, change-over valve 3, fuel tank 5 and hydraulic control one-way valve 4.
Hydraulic Pump 1 connects with change-over valve 3 by oil pipe, change-over valve 3 connects with multi-stage oil cylinder 2 by oil pipe, the rodless cavity of multi-stage oil cylinder 2 connects with hydraulic control one-way valve 4, the control end of hydraulic control one-way valve 4 connects with the rod chamber of multi-stage oil cylinder 2, the oil inlet end of Hydraulic Pump 1 is connected with oil filter 7, oil filter 7 oil inlet ends connect with fuel tank 5, and hydraulic control one-way valve 4 and change-over valve 3 connect with fuel tank 5 by oil pipe.
Between the oil outlet end of Hydraulic Pump 1 and fuel tank 5 by pass valve 6 is installed, the effect of by pass valve 6 is to guarantee that hydraulic system working pressure is no more than the pressure of setting.
Oil outlet end at Hydraulic Pump 1 also is equipped with oil pressure indicator 8, is used for showing the operation pressure of hydraulic efficiency pressure system.
When compressed garbage, Hydraulic Pump 1 work makes hydraulic oil enter the rodless cavity of multi-stage oil cylinder 2 from change-over valve 3, hydraulic oil in the rod chamber of multi-stage oil cylinder 2 directly flows back to fuel tank 5 through change-over valve 3, because at this moment the pressure of rod chamber is very low, hydraulic control one-way valve 4 can not be opened.
When push pedal is return, Hydraulic Pump 1 work makes hydraulic oil enter the rod chamber of multi-stage oil cylinder 2 from change-over valve 3, at this moment the pressure of rod chamber is exactly the operation pressure of hydraulic efficiency pressure system, under the effect of operation pressure, hydraulic control one-way valve 4 just is opened, hydraulic oil in the rodless cavity of multi-stage oil cylinder 2 flows back to fuel tank 5 through hydraulic control one-way valve 4, make the pressure in the rodless cavity very low, multi-stage oil cylinder 2 with regard to smooth and easy, rapidly the push pedal that is installed on it is return, and, because the spill pressure of system is low, has also guaranteed the safe and reliable to operation of system.
