The spray lance lifting control system course of work is as follows: the control stick on operation tractor 49, hydraulic oil is flowed out from oil pump, enters the first hydraulic lock 36, then flow into the first raise-lower hydraulic oil cylinder 34 and the second raise-lower hydraulic oil cylinder 35 respectively, ejected by piston rod, spray boom rises; During decline, manipulation bar, hydraulic oil circuit is opened, and under gravity, compression piston bar, hydraulic oil flows back in fuel tank spray boom, and whole spray boom just have dropped.
It is as follows that spray boom launches the control system course of work, only for while: during beginning, first travel switch 46 is in open mode with third trip switch 45, second travel switch 42 is in closed condition, hydraulic oil from oil pump pressurization flow out laggard enter the second hydraulic lock 38, balanced valve 41 is flowed into again from the second hydraulic lock 38, enter the cavity of this end from the tail end of an arm oil cylinder 12 after flowing out from balanced valve 41, the piston rod promoting an arm oil cylinder 12 stretches out, now, the tail end of one arm oil cylinder 12 is pressurized state, head end is depressurization phase, after the piston rod of an arm oil cylinder 12 stretches out completely, hydraulic oil flows out from the tail end of an arm oil cylinder 12 tail end entering two arm upper cylinders 311 to be released the piston rod of two arm upper cylinders 311, the rear end of oil cylinder 312 under oil part inflow two arms in the cavity of the head end of two arm upper cylinders 311, a part is refluxed by third trip switch 45 and three arm oil cylinder 321 head end releases, along with the release of two arm upper cylinder 311 piston rods, second section spray boom slowly launches, first travel switch 46 slowly cuts out, second travel switch 42 is slowly opened, when the exhibition of second section spray boom is to assigned address, second travel switch 42 is opened completely, from the hydraulic oil that two arm upper cylinder 311 tail ends flow out, under a part flows into two arms, the piston rod of front end is released by oil cylinder 312 front end, second section spray boom is locked in assigned address, the piston rod of three arm oil cylinders 321 is released by the tail end that another part enters three arm oil cylinders 321, section three, spray boom slowly launches, third trip switch 45 slowly cuts out, after Section of three spray boom launches completely, the hydraulic oil flowed out from three arm oil cylinder 321 tail ends enters from the head end of four arm oil cylinders 331 and is regained by its piston rod, section four, spray boom launches, now, whole spray boom launches completely, launch operation to stop, finally, then pressure oil pump, hydraulic oil enters the head end of balancing cylinder 25 by the second threeway 39, and the piston rod of balancing cylinder 25 is regained, and opens spray boom lockable mechanism, makes spray boom be in centrally axis free swing state.When spray boom folds, its course of work is contrary to the above, does not repeat them here.
Lockable mechanism 8 course of work is as follows: when spray boom stretches, the cylinder bar of balancing cylinder 25 is for stretching out shape, locking rod 27 falls into pit 19, pit 19 is pinned, make it can not swing around gravity axis 11, realize the lock-out state of spray boom, it is made not swing, prevent owing to stretching asynchronous and causing the damage of spray boom and facility, until spray boom both sides are opened all completely, now two lateral balances, spray boom center of gravity and gravity axis 11 axis coinciding, due to the rising of hydraulic pressure, balancing cylinder 25 cylinder bar shrinks, locking rod 27 departs from pit 19, fixing spray boom 9 can swing around gravity axis 11, rocking of walking machine is down to minimum on the impact of spray boom, when spray boom folds, the cylinder bar of balancing cylinder 25 extends, and locking rod 27 falls into spray boom pit 19, is pinned by fixing spray boom 9, makes it can not swing around gravity axis 119, realizes the lock-out state of spray boom.
Course of work when spray boom launches is as follows: the output of an arm oil cylinder 12 stretches out, distance between the top of output and the tail end of an arm oil cylinder 12 is elongated, two ends due to an arm oil cylinder 12 are all fixing, therefore the output of an arm oil cylinder 12 rotates around the pin joint of itself and fixing spray boom 9 with regard to driving the first folding spray rod 30, when the first folding spray rod 30 is the level of state, in fold mechanism between first folding spray rod 30 and the second folding spray rod 31, the output of two arm upper cylinders 311 stretches out, its output drives the active summit 202 of set square 20 to circle around fixed vertices 201, drive passive summit 203 also to circle around fixed vertices 201 simultaneously, passive summit 203 drives the second folding spray rod 31 to circle around the tie point of the second folding spray rod 31 and the first folding spray rod 30 by connecting rod again, meanwhile, under two arms, the output of oil cylinder 312 stretches out, card column 314 is stuck in draw-in groove 313, like this, second folding spray rod 31 just expands, by that analogy, 3rd folding spray rod 32 launches with the direction contrary with the second folding spray rod 31, 4th folding spray rod 33 launches with the direction contrary with the 3rd folding spray rod 32 again, whole spray boom just presents deployed condition.
Course of work when packing up spray boom is contrary to the above, does not repeat them here.
Boom sprayer is in operation process, if the 4th folding spray rod 33 encounters barrier when advance or retrogressing, the constraint being subject to the hydraulic jack 10 of fold mechanism due to rotating shaft 13 can not rotate, now the 4th folding spray rod 33 will drive fixed block 15 to rotate, groove 18 is separated with transverse bar 14 simultaneously, transverse bar 14 contacts with fixed block 15 lower surface, fixed block 15 raises, when barrier is removed, under the action of the spring 16, 4th folding spray rod 33 revert to deployed condition again, such structure just slow down the impact of barrier, boom sprayer is made to obtain protection, also barrier is made to obtain protection, particularly when barrier is people.
Except technical characteristic described in specification, all the other technical characteristics are those skilled in the art's known technology.
