As shown in figs. 3 a-3 c, continue by taking left side moving parts 6 as an example, the wheelspan hydraulic adjustment device 4 of the present embodiment is main
Including hydraulic motor 41, motor fixed plate 42, duplicate sprocket 43, chain 44, adjusting screw set sliding seat 45, thrust bearing 46,
Sliding seat mounting plate 47, adjusting screw set 48, adjusting screw 49, lead screw attachment base 410 and lead screw connecting pin 411 etc., wherein adjusting
It is integral by connection rod end 481, sprocket wheel 482, casing 483 and 484 groups of nut to save screw set 48, adjusting screw 49 includes lead screw section
491 and connector sleeve 492.There is two groups of lead screws-screw set component in every suit wheelspan hydraulic adjustment device 4, it is respectively preceding to adjust
Screw mechanism and rear adjusting screw mechanism, and 6/7 rear and front end of left/right sidesway dynamic component is located at close to the position of outer square tube
It sets.Motor fixed plate 42 and sliding seat mounting plate 47 are fixed on the stringer 83 of rack 8, and lead screw attachment base 410 is fixed on left side
On the crossbeam 621 of movable stand 62.Hydraulic motor 41 is fixed on motor fixed plate 42 by bolt, nut, and 43 sets of duplicate sprocket
Torque is transmitted on the output shaft of hydraulic motor 41, and through key joint, the hydraulic oil of hydraulic motor 41 derives from spraying machine
Hydraulic system 5；The both ends pin shaft of adjusting screw set sliding seat 45 is inserted into the connecting hole of two sliding seat mounting plates 47, can
Around connection axially bored line rotation；The two sides that adjusting screw covers sliding seat 45 are equipped with thrust bearing 46, increase or subtract in adjustment wheelspan
Hour reduces the rotary resistance of adjusting screw set 48.The connection rod end 481 of adjusting screw set 48 is interspersed in adjusting screw set activity
In the hole of seat 45 and thrust bearing 46, the end of thread is secured with nuts；Nut 484 and adjusting screw 49 on adjusting screw set 48
Lead screw section 491 connect；The lead screw section 491 of adjusting screw 49 is connect with the nut 484 on adjusting screw set 48, the company of the other end
Female connector 492 is fixed on lead screw attachment base 410 by lead screw connecting pin 411, and one end of lead screw connecting pin 411 is equipped with resilient key,
It is fallen to prevent anti-avulsion.Two pieces chain 44 is connected between the sprocket wheel 482 on duplicate sprocket 43 and adjusting screw set 48, for passing
Pass pulling force.
Continue by taking left side moving parts 6 as an example, the course of work of the present embodiment wheelspan hydraulic adjustment device 4 is as follows: when need
When increasing the wheelspan of Self-walking sprayer with spraying rod, the connection bolt of interior square tube clamping plate 14 is first unscrewed, is in interior square tube 66
Relaxed state.Forward direction connects the hydraulic output of spraying machine hydraulic system 5 to 41 fuel feeding of hydraulic motor, makes hydraulic motor 41 is positive to turn
It is dynamic, drive adjusting screw set 48 to rotate forward by duplicate sprocket 43 and chain 44.Due to the limitation of lead screw connecting pin 411,
Adjusting screw 49 cannot be rotated around lead screw axis, and therefore, when adjusting screw set 48 rotates forward, adjusting screw 49 is by outward
Ejection pushes left side moving parts 6 to be displaced outwardly, and the wheelspan of spraying machine increases (referring to Fig. 5).Due to two on duplicate sprocket 43
The number of teeth, the size of a sprocket wheel are identical, and the number of teeth, the size of the sprocket wheel 482 on two pieces adjusting screw set 48 are also identical, therefore when hydraulic
When motor 41 drives adjusting screw 48 rotation of set by duplicate sprocket 43, chain 44 and sprocket wheel 482, front and back two pieces adjusting screw set
48 velocity of rotation is identical, and the speed that front and back two pieces adjusting screw 49 ejects outward is also identical, and front and back tire is mobile
Speed it is fully synchronized, avoid because front and back wheel movement of the foetus make it is asynchronous caused by speed is uneven, even wheelspan adjustment can not carry out
The problem of.After wheelspan adjusts, screws interior square tube clamping plate 14 and connect bolt.
When needing to reduce the wheelspan of Self-walking sprayer with spraying rod, the reversed hydraulic output for connecting spraying machine hydraulic system 5
To 41 fuel feeding of hydraulic motor, hydraulic motor 41 and duplicate sprocket 43 are rotated backward, is driven by duplicate sprocket 43 and chain 44
Adjusting screw set 48 rotates backward, and retracts adjusting screw 49 inwardly, pulls left side moving parts 6 to move inward, sprays
The wheelspan of mist machine reduces (referring to fig. 4).
Wheelspan adjustment process carries out under Self-walking sprayer with spraying rod low speed travel condition, and spraying machine tire is slowly rotating
While, outward or move inward, to reduce resistance when wheelspan adjustment.
Wheelspan hydraulic adjustment device of the invention, wheelspan is easy to adjust, practical, quick, and manufacturing cost is low, big-and-middle
Type Self-walking sprayer with spraying rod can be installed and used conveniently.
Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripe
It knows those skilled in the art and makes various corresponding changes and modifications, but these corresponding changes and change in accordance with the present invention
Shape all should fall within the scope of protection of the appended claims of the present invention.
