Wherein, it includes to unload bin gate motion control oil circuit: the hydraulic control system comprises a first hydraulic oil tank, a first hydraulic pump, a first one-way valve, a first overflow valve, a first pressure gauge, a first electromagnetic directional valve and a second electromagnetic directional valve.
A first hydraulic pump 102 is installed on a first hydraulic oil tank 101, the outlet of the pump is connected with a first one-way valve 103 through a pipeline, one end of the outlet of the one-way valve is connected with a first overflow valve 104, and the overflow outlet is directly connected back to the oil tank 101; the other end of the outlet of the one-way valve is respectively connected with 105 a first pressure gauge, 106 a first electromagnetic directional valve and 107 a second electromagnetic directional valve. 105, displaying the actual working pressure of the corresponding oil way of the 106 or 107 second electromagnetic directional valve by a first pressure gauge; 106, controlling the action of a feeding door cover by a first electromagnetic directional valve; 107 the second solenoid directional valve controls the discharge door action.
Two oil pipes are led out from a first electromagnetic directional valve 106, wherein one oil pipe is divided into two parts: the first part is firstly connected 111 with a first one-way sequence valve, then connected 112 with a balance valve through a pipeline, and finally connected 113 to an oil port at one end of the swing oil cylinder of the feeding door through an outlet of the balance valve. The second part is connected with a first hydraulic lock 115 through a pipeline and then connected with a middle rodless cavity of a double-piston rod bolt oil cylinder 116 through a pipeline. The other path is also divided into two parts: the first part is connected 114 to the second one-way sequence valve, then connected 115 to the first hydraulic lock via a line, and finally connected 116 from the hydraulic lock to the double-piston rod bolt cylinder with rod cavities at both ends. The second part is connected with a balancing valve 112 and then is connected to an oil port at the other end of the swing oil cylinder of the feeding door 113 through a pipeline.
Two oil pipes are led out from a 107 second electromagnetic directional valve, wherein one oil pipe is divided into two parts after passing through a 108-1 stop valve: the first section is connected to the 123-1/2 discharge latch cylinder rodless chamber via 122 second and 124 hydraulic locks, respectively. The second section is connected 131 to the fourth one-way sequence valve, then passes 133 through the third hydraulic lock and 135 through the fourth hydraulic lock, and then is connected 134-1/2 to the discharge gate cylinder rod chamber. The other path of the gas also is divided into two parts after passing through a 108-2 stop valve: the first section is connected to the 123-1/2 discharge gate latch cylinder rod chamber after passing through 121 a third one-way sequence valve and then 122 a second hydraulic lock and 124 a hydraulic lock, respectively. The second part passes through 132 a first one-way throttle valve, then respectively passes through 133 a third hydraulic lock and 135 a fourth hydraulic lock, and then respectively connects to 134-1/2 discharge gate cylinder rodless chambers.
Based on the above description: the vehicle-mounted hydraulic system is powered by a 24V storage battery pack, and a driving motor is a 24V direct current motor. 102 the first hydraulic pump is started. The hydraulic oil starts to work through 103 the first check valve, 104 the first spill valve.
When 106 the first electromagnetic directional valve coil c is electrified, the hydraulic oil is divided into two paths: one path reaches 116 the rod cavity of the double-piston rod bolt oil cylinder through 114 a second one-way sequence valve and 115 a first hydraulic lock, and the other path reaches 113 one end of the feed gate swing oil cylinder through 112 a balance valve. Because the set pressure of a 111 first one-way sequence valve on an oil return path of a 113 feeding door swing oil cylinder is larger than the set pressure of a 112 balance valve and the opening pressure of a 115 first hydraulic lock, hydraulic oil firstly flows into a rod cavity of a 116 double-piston-rod bolt oil cylinder, after the bolt is retracted to the bottom, the system pressure is increased to the set pressure of the 111 first one-way sequence valve, the sequence valve is opened, and the 113 feeding door swing oil cylinder drives a feeding door cover to be completely opened. When 106 first electromagnetic directional valve coil d gets electricity, hydraulic oil divides two ways: one path reaches the other end of the swing oil cylinder of the feeding door 113 through a first one-way sequence valve 111 and a balancing valve 112. The other path enters 116 a middle rodless cavity of the double-piston rod bolt oil cylinder through a first hydraulic lock 115. The second one-way priority valve set pressure on the cylinder return line 114 is greater than 112 the balance valve set pressure due to the dual piston rod pin 116. At this time, the 113 feeding gate swinging oil cylinder drives the feeding gate cover to be completely closed, the system pressure is increased to 114 second one-way sequence valve set pressure, the sequence valve is opened, and the 116 double-piston rod bolt oil cylinder extends out to lock the feeding gate cover.

The second path is connected with a rod cavity of a bolt oil cylinder of a 123-1/2 discharging door through 122/124 hydraulic locks respectively after passing through a 121 third one-way sequence valve. The third path is connected with a rodless cavity of a 134-1/2 discharge door oil cylinder through a 133/135 fourth hydraulic lock after passing through a 132 first one-way throttle valve. The fourth one-way priority valve set pressure is greater than the 122/124 hydraulic lock open pressure due to 131. Therefore, hydraulic oil firstly flows into a rod cavity of the 123-1/2 discharge door bolt oil cylinder, the bolt retracts to the bottom, the system pressure is increased to 131 the pressure set by the fourth one-way sequence valve, the sequence valve is opened, and the 134-1/2 discharge door oil cylinder extends to open the discharge door. When a coil b of a 107 second electromagnetic reversing valve is electrified, hydraulic oil is divided into three paths after passing through a 108-1 stop valve: the first path is used as a standby power interface and is connected with a 208-1L-shaped high-pressure internal thread three-way ball valve in an on-site hydraulic system through a 212-1 one-way throttle valve. The second path is connected with a rodless cavity of a 123-1/2 discharging door latch oil cylinder through an 122/124 hydraulic lock. The third path is connected with a rod cavity of a 134-1/2 discharge door oil cylinder through a 133/135 fourth hydraulic lock after passing through a 131 one-way throttle valve. As the set pressure of the 121 third one-way sequence valve is higher than the 133/135 fourth hydraulic lock opening pressure, hydraulic oil firstly flows into 131 the fourth one-way sequence valve, then respectively flows into 134-1/2 discharge door oil cylinders through 133/135 fourth hydraulic locks to form rod cavities, and the discharge door oil cylinders retract to the bottom. The system pressure is increased to 121, the third one-way sequence valve sets the pressure, the sequence valve is opened, the 123-1/2 discharge door bolt oil cylinder extends out, and the discharge door is locked.

The second pressure gauge 205 displays 206 actual working pressure of a corresponding oil way of the third electromagnetic directional valve; 206 the third electromagnetic directional valve controls the action of the pushing multistage oil cylinder. Two oil pipes are led out from a third electromagnetic reversing valve 206, wherein one oil pipe is divided into two parts after passing through a 207-1 double self-sealing quick joint and a 208-1L-shaped high-pressure internal thread three-way ball valve: one part of the hydraulic cylinder passes through a 209-1 one-way throttle valve and a 210 fifth hydraulic lock and is connected with 211 to push a rod cavity of the multistage cylinder.

In a further embodiment, the discharge hydraulic unit further comprises: and the standby power unit is arranged to provide standby power for the discharging assembly. Because the vehicle-mounted hydraulic system is arranged in the vehicle-mounted box body and moves along with the vehicle. When a fault occurs, a maintenance worker is difficult to timely arrive at the site for maintenance. The garbage can be retained in the box body for a long time and can not be unloaded.
