Multi-functional slide valve 2 collects safety valve, overflow valve, ceding of Taiwan control valve 23, steering control valve 24 and hydraulic control one-way valve 25
The compound hand-operated valve being integrally formed.
In the present embodiment, the ceding of Taiwan oil cylinder 3 for controlling taiwan cut off and landing includes two ceding of Taiwan oil cylinders in parallel.
A kind of synchronous valve concrete operating principle for controlling harvester steering and taiwan cut off and landing of the invention is described below：
1 high-voltage oil liquid of oil sources can reach the P mouth of ceding of Taiwan control valve 23 and the P1 mouth of steering control valve 24 simultaneously, and the ceding of Taiwan is returned
Road and steering circuit are independent of each other, and work normally.Safety valve 21 is an overflow valve in fact, for guaranteeing the pressure of hydraulic system
13.5MPa is not exceeded, overflow valve 22, which is for ensuring that, turns to the operating pressure in circuit not higher than 7-8MPa, two overflow valves
Pressure can be set.
When ceding of Taiwan control valve 23 is in middle position, P and T1 are communicated, and high pressure oil reaches steering control valve 24 by P and T1
P ' mouth, the high pressure oil of oil liquid 1, which fully enters, at this time turns to circuit, and elevating loop, which will not influence, turns to circuit.When ceding of Taiwan control valve
24 be in left position when, T1 be closing mouth, do not have oil liquid influence turn to circuit.High-voltage oil liquid passes through P mouthfuls, A mouthfuls and fluid-control one-way
Valve 25 enters the rodless cavity of ceding of Taiwan oil cylinder 3, and ceding of Taiwan oil cylinder 3 is two single-acting cylinders in parallel, and ceding of Taiwan cylinder piston rod is stretched at this time
Out, the ceding of Taiwan is risen.When ceding of Taiwan control valve 23 is in right position, T1 is closing mouth, and not having oil liquid influences to turn to circuit.High pressure oil
Liquid is by the control mouth of P mouthfuls and B mouthfuls arrival hydraulic control one-way valves 25, and hydraulic control one-way valve 25 is opened at this time, and ceding of Taiwan oil cylinder 3 is due to the ceding of Taiwan
Self weight or other external force, cause piston rod to retract, and rodless cavity oil liquid is into 25 oil return of hydraulic control one-way valve opened is crossed, through A mouthfuls and T mouthfuls
Oil return box.In summary the function narration of three positions of ceding of Taiwan control valve, no matter ceding of Taiwan switching valve is in any position, not
It influences whether to turn to circuit.
When steering control valve 24 is in middle position, communicated with oil return fuel tank 6 due to A mouthfuls, B mouthfuls, B1 mouthfuls, P mouthfuls and T mouthfuls,
High-voltage oil liquid passes through the direct oil return box of P ' and T ', and steering cylinder will not act.
When steering control valve 24 is in the first from left position, A ', P1 and P ' are communicated, and oil liquid reaches the rodless cavity of left steering oil cylinder 4,
4 piston rod of left steering oil cylinder stretches out at this time.B1 arrival was passed through in the slow oil return of the rod chamber of left steering oil cylinder and right turn oil cylinder
T ' mouth, then arrive oil return fuel tank 6.The rodless cavity of right turn oil cylinder 5 passes through B ' and T ' it is directly connect with fuel tank, pressure zero, still,
Due to the presence of the throttling channel between B1 and T, it will lead to 5 rod chamber pressure of right turn oil cylinder slightly larger than rodless cavity pressure, turn right
It can slightly be retracted to the piston rod of oil cylinder 5.The piston rod outreach of left steering oil cylinder 4 is greater than right turn cylinder piston rod at this time
Distance is retracted, the two collective effect causes harvester to turn to the left.
When steering control valve is in the second from left position, A ', P1 and P ' are communicated, and oil liquid reaches left steering oil cylinder rodless cavity, at this time
4 piston rod of left steering oil cylinder stretches out.Since the B1 that the rod chamber of left steering oil cylinder 4 and right turn oil cylinder 4 is connected is closing mouth,
It will lead to pressure to be continuously increased, the piston rod of driving right turn oil cylinder 5 retracts.The piston rod of left steering oil cylinder 4 stretches out at this time
Distance is equal to the retraction distance of 5 piston rod of right turn oil cylinder, and the two collective effect leads to harvester pivot stud to the left.
When steering control valve is in right one, B ', P1 and P ' are communicated, and oil liquid reaches the rodless cavity of right turn oil cylinder 5, this
When right turn oil cylinder 5 piston rod stretch out.The slow oil return of the rod chamber of left steering oil cylinder 4 and right turn oil cylinder 5, reaches by B1
T ' mouth, then arrive oil return fuel tank 6.The rodless cavity of left steering oil cylinder 4 passes through B ' and T ' it is directly connect with oil return fuel tank 6, pressure zero,
But due to B1 and T ' between throttling channel presence, will lead to 4 rod chamber pressure of left steering oil cylinder slightly larger than rodless cavity pressure
The piston rod of power, left steering oil cylinder 4 can be retracted slightly.The piston rod outreach of right turn oil cylinder 5 is greater than left steering oil cylinder 4 at this time
Piston rod retraction distance, the two collective effect causes harvester to turn to the right.
When steering control valve is in right two, B ', P1 and P ' are communicated, and oil liquid reaches the rodless cavity of right turn oil cylinder 5, this
When right turn oil cylinder 5 piston rod stretch out.Since the B1 that the rod chamber of left steering oil cylinder 4 and right turn oil cylinder 5 is connected is envelope
It is silent, it will lead to pressure and be continuously increased, the piston rod of driving left steering oil cylinder 4 retracts.The piston rod of right turn oil cylinder 5 at this time
Outreach is equal to the retraction distance of the piston rod of left steering oil cylinder 4, and the two collective effect leads to harvester pirouette to the right
To.
It should be appreciated that described above, the specific embodiments are only for explaining the present invention, is not intended to limit the present invention.By
The obvious changes or variations that spirit of the invention is extended out are still in the protection scope of this invention.
