Ground gap adjusts process by taking left front suspension assembly 23 as an example, when rising high-clearance, first opens hydraulic Lock device, high pressure oil Liquid enters ground gap adjustment oil cylinder 3, pushes the cylinder body of ground gap adjustment oil cylinder 3 to move up along piston rod, ground gap adjusts oil cylinder 3 Cylinder body drives leading truck 4, and leading truck 4 drives draft hitch 5 to move up again, and the crossbeam 53 of draft hitch 5 drives vehicle frame again, into And vehicle body is driven to move up, ground gap increases;Required for being increased to when ground gap height, hydraulic system fuel cut-off, and close It is latched locking apparatus, gap height in ground is no longer changed.
When dropping low ground space, hydraulic Lock device is opened, high-voltage oil liquid adjusts under spraying machine vehicle body gravity from ground gap The hydraulic fluid port of oil cylinder 3 flows out, so that the cylinder body of ground gap adjustment oil cylinder 3 is moved down along piston rod, ground gap is adjusted for the reduction of oil liquid The cylinder body of oil cylinder 3 drives leading truck 4, and leading truck 4 drives draft hitch 5 to move down again, and the crossbeam 53 of draft hitch 5 drives again Vehicle frame, and then vehicle body is driven to move down, ground gap reduces;Required for being reduced to when ground gap height, hydraulic system stops supplying Oil, and hydraulic Lock device is closed, gap height in ground is no longer changed.
Since ground clearance adjustment apparatus links together with draft hitch, when wheel passes through uneven road surface, ground faces tire Excitation can pass to draft hitch by ground clearance adjustment apparatus, pass to vehicle frame again after draft hitch buffer shock-absorbing, disappear The body vibrations due to caused by the injustice of ground are subtracted, gap reaches spraying machine of the present invention not only adjustablely Required height also has good ride performance.
The ground gap adjustment process of left rear suspension assembly 26, right rear suspension assembly 33 and right front suspension assembly 34 and left front suspension Assembly 23 is identical.Their ground gap both can be separately adjustable, can also combine adjusting, to adjust the body gesture of spraying machine, makes Spraying machine has the adaptability to different terrain.Fig. 4 c show spraying machine on the road surface of ramp when driving, and the two of lower side The ground clearance adjustment apparatus of a suspension assembly rises high-clearance, and the ground gap regulating device of two suspension assemblies of higher side reduces ground Gap, final adjustment result make spraying locomotive keep horizontality on ramp, improve spraying machine riding comfort and Driving safety.
Wheelspan adjusts process so that the near front wheel of front-wheel Wheel gauge regulator 35 is away from adjustment process as an example, when increasing wheelspan, oil Liquid enters hydraulic cylinder away from the rodless cavity connection hydraulic fluid port of adjustment oil cylinder 141 by revolver, flows out hydraulic oil from rod chamber connection hydraulic fluid port Cylinder, piston rod stretch out out of cylinder body and the crossbeam 53 of draft hitch 5 are driven to slide in and out along left sliding bearing 131, crossbeam 53 Left front suspension assembly 23 is driven to slide in and out, wheelspan increases.
When reducing wheelspan, oil liquid enters hydraulic cylinder away from the rod chamber connection hydraulic fluid port of adjustment oil cylinder 141 by revolver, from no bar Chamber connects hydraulic fluid port and flows out hydraulic cylinder, and piston rod retract cylinder is interior and drives the crossbeam 53 of draft hitch 5 along left sliding bearing 131 slid inwards, crossbeam 53 drive left front 23 slid inward of suspension assembly, and wheelspan reduces.
The off-front wheel that front tread adjusts device 35 adjusts the left rear wheel of device 32 away from adjustment away from adjustment process, rear track Process and off hind wheel are identical away from adjustment process away from adjustment process and the near front wheel of front tread adjustment device 35.Their wheelspan was both Can be separately adjustable, adjusting can also be combined, make spraying machine that there is better adaptability to different line space crops.
State when the ground gap height and Track width that Fig. 4 b show spraying machine of the present invention are adjusted to maximum, it is spraying at this time Machine maximally gap height value H2With maximum Track width value D2Respectively 2000mm and 4000mm.Ground gap and wheelspan adjustable range point It Wei not 0~500mm and 0~800mm.
