The present invention operation principle be：
When agricultural machinery normally travel mainly based on the steering of front-wheel 3, operator switchs the front-wheel steer on instrument desk
19 move to de-energized, power off front wheel electromagnetic valve 8, and 8 valve of front wheel electromagnetic valve is opened, and front-wheel 3 is in state to be diverted,
Then rear-axle steering switch 18 is moved into on-position, trailing wheel solenoid valve 16 is made to be powered, 16 valve of trailing wheel solenoid valve is closed
Oil pressure is cut off, trailing wheel 15 is in straight travel state.
When agricultural machinery carries out various operations in farmland, in addition to being turned to using front-wheel 3, it is also necessary to assist front-wheel using trailing wheel 15
3 turn to, so the front-wheel steer switch 19 and rear-axle steering switch 18 move to de-energized, 8 He of front wheel electromagnetic valve at this time
Trailing wheel solenoid valve 16 powers off, and valve is opened, and front-wheel 3 and trailing wheel 15 are in state to be diverted.
When agricultural machinery farmland carry out various operations when, when need carry out to the right or left side move when, driver first have to by
Agricultural machinery is controlled in straight travel state, is mainly locked in the rear-axle steering driving mechanism by the pneumatic locking device
Any steering support arm 4, the keyhole for then making pneumatic locking device inflation that locking bar be made to exit locking support arm 25, trailing wheel 15, which is in, to be waited to turn
To state, while the manual reverse of direction handle 12 described in right hand moving adjusts the spool of the reversal valve 11, makes the reversal valve 11
P mouths connected with B mouthfuls, A mouthfuls connected with O mouthfuls, driver turns left steering wheel 1 at this time, drives the spool of rotary valve steering gear 2
Turn left, pressure oil is entered by the P mouths of rotary valve steering gear 2, by A mouthfuls of outputs, enters front-wheel steer driving mechanism by pipeline
7 right chamber of hydraulic cylinder, and entered in rear-axle steering driving mechanism by the road by the inflow of the P mouths of the reversal valve 11, B mouthfuls of outflows simultaneously
7 left chamber of hydraulic cylinder, make front and rear wheel turn left simultaneously realization turn left.To the right when driving, driver by steering wheel 1 to the right
Turn.
When agricultural machinery carries out various operations in farmland, when needing to from left to right racing or spot turn, driver is to the left
Or manual reverse of direction handle 12 is pulled, the O mouths of the reversal valve 11 is made to be communicated with B mouthfuls, A mouthfuls on the basis of mobile manipulation to the right
Communicated with P mouthfuls, while the steering wheel 1 that turns right, the P mouths of rotary valve steering gear 2 is made to be communicated with B mouthfuls, A mouthfuls communicated with O mouthfuls, pressure
Oil is flowed by the P mouths of rotary valve steering gear 2, B mouthfuls of 7 left chambers of hydraulic cylinder exited into front-wheel steer driving mechanism, before described
A mouth and O mouthful of the 7 right chamber oil return of hydraulic cylinder Jing Guo rotary valve steering gear 2 in wheel steering driving mechanism is back to fuel tank, and front-wheel 3 is right
Turn, while pressure oil enters the O mouths of the reversal valve 11 and by the B mouthfuls of hydraulic cylinders exited into rear-axle steering driving mechanism 7
Left chamber, trailing wheel 15 turn left, and front-and rear-wheel steer is on the contrary, so as to fulfill agricultural machinery sharp right-hand bend or spot turn purpose.
When wheel 23 in being added between front-wheel 3 and trailing wheel 15 and middle wheel steering driving mechanism, pass through middle wheel pole changer
24 power on/off of solenoid valve to be taken turns in 22 controls, valve when solenoid valve 24 powers off is taken turns in the middle and opens, middle wheel 23 is in state to be diverted,
23 steering manipulation principles of middle wheel are identical with trailing wheel 15, and the middle wheel 23 can individually control steering.
