The single control oil circuit that hydraulic system uses in self-discharging trailer, can not control the stretching speed of hydraulic cylinder；This hydraulic pressure
It is impossible to meet the hydraulic controls of modernization for system.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of simple in structure, design conjunction is provided
Reason, self-discharging trailer power unit easy to use, it using the cooperation of two bilateral one way stop peturn valves and adjustable throttling come
The hydraulic system for controlling self-discharging trailer can ensure that hydraulic cylinder carries out rapid increase, while can also adjust hydraulic cylinder and let out
The speed declined when pressure avoids pressure release is too fast from causing self-discharging trailer that accident occurs, more securely and reliably.
To achieve the above object, the technical solution adopted in the utility model is：It include driving motor, gear pump, fuel tank,
Check valve, overflow valve, adjustable throttling, two bilateral one way stop peturn valves；The driving motor and gear pump are coaxially connected, and
Gear pump lower end is connect by strainer with fuel tank, and the upper end of the gear pump is connect with check valve and overflow valve respectively, overflow
In valve refluxing opening and fuel tank；The outlet end of the check valve is connect with oil circuit interface, two bilateral one way stop peturn valves respectively, and
Two bilateral one way stop peturn valves are connected to fuel tank by adjustable throttling.
Preferably, be attached by transition valve plate between the driving motor and fuel tank, and transition valve plate is outer
Side is connected with overflow valve, adjustable throttling, two bilateral one way stop peturn valves.
Preferably, the input end of two bilateral one way stop peturn valves is provided with filter screen.
With the above structure, the utility model has the beneficial effect that：A kind of self-discharging trailer described in the utility model is used dynamic
Power unit, it controls the hydraulic system of self-discharging trailer, energy using the cooperation of two bilateral one way stop peturn valves and adjustable throttling
Enough ensure that hydraulic cylinder carries out rapid increase, while the speed declined when hydraulic cylinder pressure release can also be adjusted, avoids pressure release
Cause self-discharging trailer that accident occurs soon, more securely and reliably.The utility model has simple in structure, and setting is reasonable, cost of manufacture
Low advantage.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the mounting structure schematic diagram of the utility model.
Reference sign：
Driving motor 1, gear pump 2, fuel tank 3, transition valve plate 4, check valve 5, overflow valve 6, adjustable throttling 7, two are double
Logical one way stop peturn valve 8.
Specific implementation mode
Below in conjunction with the accompanying drawings, the utility model is further described.
Referring to as shown in Figure 1 and Figure 2, present embodiment adopts the following technical scheme that：It includes driving motor 1, gear
7, two pump 2, fuel tank 3, check valve 5, overflow valve 6, adjustable throttling bilateral one way stop peturn valves 8；The driving motor 1 and tooth
Wheel pump 2 is coaxially connected, and 2 lower end of gear pump is connect by strainer with fuel tank 3, the upper end of the gear pump 2 respectively with unidirectionally
Valve 5 and overflow valve 6 connect, in overflow valve refluxing opening and fuel tank 3；The outlet end of the check valve 5 respectively with oil circuit interface P,
Two bilateral one way stop peturn valves 8 connect, and two bilateral one way stop peturn valves 8 are connected to fuel tank 3 by adjustable throttling 7.
Wherein, it is attached by transition valve plate 4 between the driving motor 1 and fuel tank 3, and transition valve plate 4 is outer
Side is connected with 7, two overflow valve 6, adjustable throttling bilateral one way stop peturn valves 8；Two bilateral one way stop peturn valves 8 into
Mouth end is provided with filter screen.
The working principle of this specific embodiment:：Pass through cooperation the adding hydraulic oil of driving motor 1, gear pump 2 first
Pressure conveying, overflow valve 6 can ensure that hydraulic oil is climbed to setting pressure, and be conveyed to oil circuit interface P by check valve 5,
At this point, two bilateral one way stop peturn valves 8 are in closed state, the pressure release stage controls hydraulic oil circulation speed by adjustable throttling 7
The speed that rate carrys out control cylinder decline even stops at designated position, more securely and reliably.
With the above structure, the utility model has the beneficial effect that：It is using two bilateral one way stop peturn valves and is adjusted
Stream valve coordinates to control the hydraulic system of self-discharging trailer, can ensure that hydraulic cylinder carries out rapid increase, while can also adjust
The speed declined when hydraulic cylinder pressure release is saved, avoids pressure release is too fast from causing self-discharging trailer that accident occurs, more securely and reliably.
The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the right of the utility model.
