Speed and steering, such as, turn over barrel oil cylinder 10 and stretch out lifting refuse receptacle, and the output fluid of two-way quantitative pump/motor 4 is big to barrel oil cylinder 10 is turned over
Chamber, due to loculus oil return, the flow-rate ratio oil-feed of loculus oil return is little, therefore 5 tapping of accumulator and loculus collaborate to two-way quantitative pump/
4 fuel feeding of motor；When turning over the retraction of barrel oil cylinder 10, variable speed electric motors, particularly 1 is turned to and is changed, now oil cylinder loculus feed liquor, and liquid is returned in big chamber, returns liquid stream
More than 4 necessary flow of two-way quantitative pump/motor, redundance is stored amount into accumulator 5, therefore accumulator 5 can play stream
Flux matched effect.
When 11 action of elevating ram, the second 2/2-way reversal valve VD2, the 6th 2/2-way reversal valve VD6 obtain conductance
It is logical, the first 2/2-way reversal valve VD1, the 3rd 2/2-way solenoid directional control valve VD3 ~ the 5th 2/2-way solenoid directional control valve VD5,
7th 2/2-way solenoid directional control valve VD7 ~ the 8th 2/2-way solenoid directional control valve VD8 dead electricity is closed, when elevating ram 11 stretches out
Similar with barrel oil cylinder 10 is turned over, when retraction transfers compression mechanism, now the gravity of compression mechanism causes two-way quantitative pump/motor 4
Motor operating conditions are operated in, now motor is in generating state, so gravitional force can be converted into power storage in power current
Chi Zhong.
When scraper plate 12 action of oil cylinder, the 3rd 2/2-way reversal valve VD3, the 7th 2/2-way solenoid directional control valve VD7 are obtained
Conduct, the first 2/2-way solenoid directional control valve VD1 ~ the second 2/2-way solenoid directional control valve VD2, the 4th 2/2-way electromagnetism are changed

12 operating modes for extending and retracting are similar with elevating ram 11.
When 13 action of skateboard tank, the 4th 2/2-way solenoid directional control valve VD4, the 8th 2/2-way solenoid directional control valve
VD8 must be conducted, the first 2/2-way solenoid directional control valve VD1 ~ the 3rd 2/2-way solenoid directional control valve VD3, the 5th 2/2-way
Solenoid directional control valve VD5 ~ the 7th 2/2-way solenoid directional control valve VD7 dead electricity is closed, when skateboard tank 13 is retracted, when second pressure is passed
When 19 measuring pressures of sensor are less than setting value Ps, 152 dead electricity of solenoid directional control valve in counterbalance valve 15, when pressure is more than or equal to setting value
During Ps, then the solenoid directional control valve 152 obtains electric, makes push pedal oil cylinder 17 retract, completes rubbish loading process.
When dumper is in dumping ground, master controller 14 makes reversal valve dead electricity in electromagnetic relief valve 8, starts auxiliary hydraulic pump
7, control 16 left side electric magnet of three-position four-way electromagnetic directional valve obtain it is electric make valve in left position, such push pedal oil cylinder 17 stretches out, completes
Refuse-unloading process.
