It refer to the signal that Fig. 3-4, Fig. 3 is folding process on the right side of spraying machine spray lance fold mechanism of the present invention
Figure；Fig. 4 is the structural representation of folded state on the right side of spraying machine spray lance fold mechanism of the present invention.Below in conjunction with
Fig. 3-4 illustrates the course of work of spraying machine spray lance fold mechanism of the present invention.As shown in Figure 3-4, folding is worked as
Stacked group part need from the job state of expansion be changed into the travel position of folding when, spraying machine pilot control liquid
Pressure system makes the piston rod 1222 of hydraulic jack 122 retract (length of oil cylinder shortening), drives first to fold
The back flap hinge carrier bar 1242 of flap 1241 and second is acted together, by inner side spray boom truss 1211, first
The double leval jib of back flap hinge carrier bar 1241, the second back flap hinge carrier bar 1242 and the middle composition of spray boom truss 1212
Mechanism produce relative motion, make middle spray boom truss 1212 with rotating pin 133 be axis relative to inner side
Spray boom truss 1211 is rotated clockwise, between inner side spray boom truss 1211 and middle spray boom truss 1212
Angle progressively reduced by 180 degree.Now, by spray boom link 11, inner side spray boom truss 1211, folding
The quadric chain of folded push rod 123 and the middle composition of spray boom truss 1212 produces relative motion, promotes inner side
Spray boom truss 1211 is that axis is rotated counterclockwise relative to spray boom link 11 with rotating pin 134.
Middle spray boom truss 1212 is that axis is made clockwise relative to inner side spray boom truss 1211 with rotating pin 133
During rotation, by inner side spray boom truss 1211, folding pull rod 126, revoliving arm 12121 and middle spray boom truss
1212 composition quadric chains produce relative motions, promote revoliving arm 12121 using its center hole a as
Axis is rotated counterclockwise relative to middle spray boom truss 1212, by turning round pull bar 127, bidirectional modulation
Screw rod 128, tensioning extension spring 129, the pulling of chain 1251, band movable sprocket 125 and outside spray boom link
1213 and outside spray boom truss 1214 together with rotating pin 131 be axis relative to middle spray boom truss
1212 rotate counterclockwise, the angle between middle spray boom truss 1212 and outside spray boom link 1213
Progressively reduced by 180 degree.When the piston rod 1222 of hydraulic jack 122 is fully retracted into, (length of oil cylinder is most short
When), between inner side spray boom truss 1211 and middle spray boom truss 1212, the middle and of spray boom truss 1212
The angle of outside spray boom link 1213 is changed into 0 degree, and spray boom truss is folded into travel position position simultaneously
(see accompanying drawing 4).
Expansion process and folding process when foldable assembly needs to be changed into job state from travel position is suitable
Sequence is interior on the contrary, spraying machine pilot control hydraulic system stretches out the piston rod 1222 of hydraulic jack 122
Side spray bar truss 1211, middle spray boom truss 1212 and outside spray boom link 1213 are in a hydraulic oil
Cylinder 122, three groups of foregoing quadric chains and revolution pull bar 127, bidirectional modulation screw rod 128, tensioning
Under the collective effect of extension spring 129, chain 1251 and sprocket wheel 125, while being launched into job position.
In addition, outside spray boom link 1213 and outside spray boom truss 1214 are constituted into outside bar spray assembly,
Acted together in spray boom folding, expansion and spraying operation；In operation process, when outside spray boom truss 1214
When encountering the barriers such as trees, electric pole, the pressure of compression spring 14 can be overcome around 132 turns of rotating pin
Move to get around barrier, it is to avoid spray boom is damaged；After the 1214 cut-through thing of spray boom truss of outside, outside
Spray boom truss 1214 under gravity, can rotate back into original position again, be pressed in outside spray boom and connect
Connect on frame 1213.Thrust bearing 1210 is arranged on middle spray boom truss 1212 and outside spray boom link 1213
Between, to reduce the resistance (frictional force) during the bar spray assembly revolution of outside.In revolution pull bar 127 and chain
The tensioning extension spring 129 set between bar 1251, the influence to eliminate foozle, makes chain 1251 begin
Impact when being in tensioning state eventually, and absorbing outside bar spray assembly action, the size of its pre-tensioning can be with
It is adjusted by bidirectional modulation screw rod 128.
The spraying machine spray lance fold mechanism of the present invention, by a hydraulic jack and three groups of quadric chains
Collective effect, folds or deploys while realizing inner side, middle and outside spray boom truss, reduce folding
Or duration of run, also save spraying machine manufacturing cost.
Presently preferred embodiments of the present invention is above are only, not for limiting the scope that the present invention is implemented,
In the case of without departing substantially from spirit of the invention and its essence, those skilled in the art work as can be according to the present invention
Various corresponding changes and deformation are made, but these corresponding changes and deformation should all belong to appended by the present invention
