Angle value D1It is all minimum, respectively 1500mm and 3200mm.
Ground gap adjustment process, as a example by left front suspension assembly 23, when rising high-clearance, first opens hydraulic Lock device, hydraulic oil
Liquid enters ground gap and adjusts oil cylinder 3, and the cylinder body promoting ground gap to adjust oil cylinder 3 moves up along piston rod, and ground gap adjusts oil cylinder 3
Cylinder body drives leading truck 4, and leading truck 4 drives again draft hitch 5 to move up, and the crossbeam 53 of draft hitch 5 drives again vehicle frame, enters
And driving vehicle body to move up, ground gap raises；When being increased to required ground gap height, hydraulic system fuel cut-off, and close
Locking locking apparatus, ground gap height no longer changes.
During fall low ground space, opening hydraulic Lock device, high-voltage oil liquid adjusts from ground gap under spraying locomotive body action of gravity
The hydraulic fluid port of oil cylinder 3 flows out, and the cylinder body that the minimizing of fluid makes ground gap adjust oil cylinder 3 moves down along piston rod, and ground gap adjusts
The cylinder body of oil cylinder 3 drives leading truck 4, and leading truck 4 drives again draft hitch 5 to move down, and the crossbeam 53 of draft hitch 5 drives again
Vehicle frame, and then drive vehicle body to move down, ground gap reduces；When being reduced to required ground gap height, hydraulic system stops supplying
Oil, and close hydraulic Lock device, ground gap height no longer changes.
Owing to ground clearance adjustment apparatus links together with draft hitch, when wheel is through uneven road surface, and ground is in the face of tire
Excitation can pass to draft hitch by ground clearance adjustment apparatus, after draft hitch buffer shock-absorbing, pass to vehicle frame again, disappear
Having subtracted the body vibrations caused due to ground injustice, spraying machine the most of the present invention is possible not only to ground clearance adjusting and reaches
Required height, also has good ride performance.
The ground gap of left rear suspension assembly 26, right rear suspension assembly 33 and right front suspension assembly 34 adjusts process and left front suspension
Assembly 23 is identical.Their ground gap both can be with independent regulation, it is also possible to combine regulation, to adjust the body gesture of spraying machine, made
Spraying machine has the adaptability to different terrain.Fig. 4 c show spraying machine when travelling on road surface, ramp, the two of relatively low side
The ground clearance adjustment apparatus of individual suspension assembly rises high-clearance, and the ground gap adjusting means of two suspension assemblies of higher side reduces ground
Gap, the final result that adjusts makes spraying locomotive keep level on ramp, improve the riding comfort of spraying machine with
Driving safety.
Wheelspan adjusts process by the near front wheel of front-wheel Wheel gauge regulator 35 as a example by adjustment process, when increasing wheelspan, and oil
Liquid is connected hydraulic fluid port by revolver away from the rodless cavity adjusting oil cylinder 141 and enters hydraulic jack, connects hydraulic fluid port effluent force feed from rod chamber
Cylinder, piston rod stretches out in cylinder body and drives the crossbeam 53 of draft hitch 5 to slide in and out along left sliding bearing 131, crossbeam 53
Driving left front suspension assembly 23 to slide in and out, wheelspan increases.
When reducing wheelspan, fluid is connected hydraulic fluid port by revolver away from the rod chamber adjusting oil cylinder 141 and enters hydraulic jack, from without bar
Chamber connects hydraulic fluid port effluent compressing cylinder, and piston rod retract cylinder is interior and drives the crossbeam 53 of draft hitch 5 along left sliding bearing
131 slid inward, crossbeam 53 drives left front suspension assembly 23 slid inward, and wheelspan reduces.
The off-front wheel of front tread adjusting apparatus 35 away from adjust process, rear track adjusting apparatus 32 left rear wheel away from adjustment
Process is identical away from the process of adjustment with the near front wheel of front tread adjusting apparatus 35 away from the process of adjustment with off hind wheel.Their wheelspan was both
Can be with independent regulation, it is also possible to combine regulation, make spraying machine that different rows spacing crop is had more preferable adaptability.
State when Fig. 4 b show the ground gap height of spraying machine of the present invention and Track width is adjusted to maximum, now sprays
Machine maximally gap height value H2With maximum Track width value D2It is respectively 2000mm and 4000mm.Ground gap and wheelspan range of accommodation are divided
It is not 0～500mm and 0～800mm.
