Overflow valve 523,523 ', 533,533 ' is responsible for the pressure in each hydraulic pressure unit of adjustment, by banked direction control valves 522 or 532
Hydraulic oil enters support arm oil cylinder 531 or grass-cutting head dump ram 521 from right side A afterwards, is adjusted by overflow valve 523 or 533, set
The pressure of hydraulic circuit so that when the pressure higher than setting, the pressure release of the overflow valve 523 or 533;Hydraulic oil passes through banked direction control valves
Enter support arm oil cylinder 531 or grass-cutting head dump ram 521 from left side B after 522 or 532, adjusted by overflow valve 523 ' or 533 ',
The pressure of hydraulic circuit is set so that when the pressure higher than setting, the pressure release of the overflow valve 523 ' or 533 '.Via described flat
Logical the stopping of the weighing apparatus control hydraulic circuit of valve 525,535, when the banked direction control valves 522 or 532 is in middle position, with the balanced valve 525
Or 535 pairs of hydraulic circuits are protected.
As Figure 1-3, the present invention also provides a kind of mowing head controlling method of hay mover as described above, and major control is cut
The floating of toothed burclover.The described method comprises the following steps:
Hydraulic oil enters through the banked direction control valves 532 in the support arm hydraulic pressure unit 53, is adjusted by the overflow valve 533
Pressure whole, that hydraulic circuit is set.When the pressure of the hydraulic circuit is higher than the pressure for setting, let out using the overflow valve 533
Pressure, specifically, overflow valve 533,533 ' is responsible for the pressure in the adjustment support arm hydraulic pressure unit 53, by liquid after banked direction control valves 532
Force feed enters from right side A, is adjusted, set the pressure of hydraulic circuit by overflow valve 533 so that when the pressure higher than setting,
The pressure release of the overflow valve 533;Entered from left side B by hydraulic oil after banked direction control valves 532, adjusted by overflow valve 533 ', liquid is set
Press oil the pressure on road so that when the pressure higher than setting, the pressure release of overflow valve 533 '.Controlled via the balanced valve 535
The logical of hydraulic circuit is stopped, and when the banked direction control valves 532 is in middle position, is protected with 535 pairs of hydraulic circuits of the balanced valve
Shield.
Two float traps 534 can be respectively connected in the hydraulic pressure in-line and oil return line of the support arm oil cylinder 53, normally
Situation bottom spool presses the button 512 that fluctuates on the control panel 51 in " only " position, can make two float traps 534
Electromagnet be powered, the valve element of two float traps 534 that the in-line and oil return line with the support arm oil cylinder 531 are connected
Switched to " logical " by " only ", big chamber, the small chamber of the support arm oil cylinder 531 connect with oil return T-phase simultaneously, the support arm oil cylinder 531
Piston rod can stretch so that the working arm group 3 moves up and down in the presence of self gravitation or ground supports power.When described
When grass-cutting head 41 is above the ground level, can decline under self gravitation effect,;When during enforcement, front ground above-below direction is higher than
Or less than the ground being currently running, ground can provide a rear support power during enforcement makes the grass-cutting head 41 raise or drop
It is low, remain contact parallel to the ground.
As Figure 1-3, the described method comprises the following steps:
In the inclined hydraulic unit 52, hydraulic oil enters through the banked direction control valves 522, is adjusted by the overflow valve 523
Pressure whole, that hydraulic circuit is set;When the pressure of the hydraulic circuit is higher than the pressure for setting, let out using the overflow valve 523
Pressure, specifically, overflow valve 523,523 ' is responsible for the pressure in the adjustment inclined hydraulic unit 52, by liquid after banked direction control valves 522
Force feed enters from right side, is adjusted, set the pressure of hydraulic circuit by overflow valve 523 so that when the pressure higher than setting, institute
State the pressure release of overflow valve 523;Entered from left side by hydraulic oil after banked direction control valves 522, adjusted by overflow valve 523 ', hydraulic oil is set
The pressure on road so that when the pressure higher than setting, the pressure release of overflow valve 523 '.Hydraulic pressure is controlled via the balanced valve 525
The logical of oil circuit is stopped, and when the banked direction control valves 522 is in middle position, is protected with 525 pairs of hydraulic circuits of the balanced valve.
Two float traps can be respectively connected in the hydraulic pressure in-line and oil return line of the grass-cutting head dump ram 521
524, normal condition bottom spool presses the left and right floating buttons 513 on the control panel 51 in " only " position, and two can be made to float
The electromagnet of dynamic valve 524 is powered, and described two that the in-line and oil return line with the grass-cutting head dump ram 521 be connecteds are floating
The valve element of dynamic valve 524 is switched to " logical " by " only ", big chamber, the small chamber of the grass-cutting head dump ram 521 and meanwhile with oil return T-phase
Even, the piston rod of the grass-cutting head dump ram 521 can stretch so that the grass-cutting head 41 is in self gravitation or ground supports
Left rotation and right rotation in the presence of power.When the grass-cutting head 41 is above the ground level, can decline under self gravitation effect,;When exercising
Cheng Zhong, front ground left and right directions is higher or lower than the ground being currently running, and ground can provide an anti-branch during enforcement
Load rises or falls the grass-cutting head 41, remains contact parallel to the ground.
As Figure 1-3, methods described is further comprising the steps of:
The key floating buttons 513 on the control panel 51 are pressed, by the valve of all two float traps 523,524
Core is switched to " logical " by " only ", and the grass-cutting head 41 moves up and down and left-right rotary in the presence of self gravitation or ground supports power
Turn so that the grass-cutting head 41 can be realized automatically adjusting in left and right and upper and lower both direction, have not with the automatic front ground that adapts to
With the inclination of the gradient, height, by the gravity of itself of the grass-cutting head 41 during enforcement, remain parallel to the ground and connect
Touch.
Additionally, the present invention can also directly control banked direction control valves 522 or 532 in leftward position or right positions by handle 514,
The valve element of each two float trap 523 or 524 switches to " logical " by " only ", makes support arm oil cylinder 531 or grass-cutting head dump ram 521
Piston rod stretches out or shrinks, and realizes control manually, makes the rapid decrease of working arm group 3 or rising, makes the quick left rotation and right rotation of mowing.
