Abstract

The invention relates to a spray lance lifting device of a pesticide spraying vehicle. The spray lance lifting device comprises: a, a left chain wheel base and a right chain wheel base (3 and 11) respectively connected at two ends of a main machine frame (9), wherein a second chain wheel (12) and an oil cylinder (10) are connected on the right chain wheel base (11), a group of movable chain wheels (6) connected onto a chain wheel base (7) are connected on the oil cylinder (10), a first chain wheel (4), a third chain wheel (15), a left chain and a right chain (5 and 13) are connected onto the left chain wheel base (3), and the left chain and the right chain respectively extend downward after being connected with the corresponding movable chain wheels (6), the first chain wheel (4), the second chain wheel (12) and the third chain wheel (15); and b, a lifting frame (8) and lifting rods (1) connected on two sides of the lifting frame (8), wherein two ends of the lifting frame are respectively connected with the extending ends of the left chain and the right chain, and the lighting rods (1) are in matching connection with a stand column (2). By adopting the technical scheme, the spray lance lifting device of the pesticide spraying vehicle is wide in using range, easy, convenient and practical in structure, time-saving, energy-saving and the like.

Description

A kind of pesticide spray car spray boom lifting device

Technical field:

The present invention relates to a kind of farmland spray machine tool, particularly a kind of pesticide spray car spray boom lifting device.

Background technology:

At present, spray insecticide in the large tracts of land farmland adopts the modes of mechanical spray medicines more, and present mechanical spray technique, generally to use agricultural machine to carry out, the spray boom height of agricultural machine is all fixed, due to the difference of variety of crops and the variation of growth time, the height of crops also changes occuring, so the use of agricultural machine is restricted.

Summary of the invention

The purpose of this invention is to provide a kind of scope of application wide, features simple structure is practical, time saving and energy saving novel spraying machine.

To achieve these goals, the present invention has adopted following technical scheme:

The present invention relates to a kind of scale insecticide sprayer spray boom lifting device, mainly comprise:

Column, left chain pulley seat, right chain pulley seat that a, mainframe and two ends connect, be connected with sprocket wheel on left and right chain pulley seat, also be connected with oil cylinder on mainframe, be connected with chain pulley seat on the piston rod of the oil cylinder other end, be connected with one group of coaxial sprocket wheel on chain pulley seat, be fixedly connected with respectively left chain and right chain on left chain pulley seat, left and right chain connects respectively the backward downward-extension of corresponding sprocket wheel;

The guide post that b, hoisting frame and both sides connect, two ends, hoisting frame left and right are fixedly connected with the end of right chain to downward-extension with left chain respectively, and guide post and column are connected;

Owing to having adopted technique scheme, make the present invention have the scope of application wide, the advantage such as features simple structure is practical, and is time saving and energy saving.

For more detailed explanation the present invention, following accompanying drawing provides a most preferred embodiment.

Description of drawings:

Fig. 1 is spray boom minimum state view of the present invention:

Fig. 2 is the high state view of spray boom of the present invention:

Fig. 3 is A to view:

Fig. 4 is the B-B view.

Embodiment:

As Fig. 1, Fig. 3, shown in Figure 4, the present invention relates to a kind of spray boom lifting device, it comprises:

a, the column 2 that mainframe 9 and two ends connect, mainframe 9 two ends are connected with respectively right chain pulley seat 11, left chain pulley seat 3, be connected with the second sprocket wheel 12 and oil cylinder 10 on right chain pulley seat 11, be connected with chain pulley seat 7 on the piston rod of oil cylinder 10 other ends, be connected with coaxial one group on chain pulley seat 7 and move sprocket wheel 6, be connected with the first sprocket wheel 4 on left chain pulley seat 3, the 3rd sprocket wheel 15 and the left chain 5 that is fixedly connected with, right chain 13, left chain 5 and mobile sprocket wheel 6, the 3rd sprocket wheel 15 connects backward downward-extension, right chain 13 moves sprocket wheel 6 with another, the first sprocket wheel 4, the second sprocket wheel 12 connects backward downward-extension,

The elevating lever 1 that b, hoisting frame 8 and both sides connect, the two ends of hoisting frame 8 are fixedly connected with to an end of downward-extension with left chain 5, right chain 13 respectively, and the roller 14 on elevating lever 1 and column 2 is connected.

As seen from Figure 2, by 10 work of HYDRAULIC CONTROL SYSTEM oil cylinder, the piston rod of oil cylinder 10 is retracted, coaxial one group is moved sprocket wheel 6 and is strained and fixed and is connected to left chain 5, right chain 13 on left chain pulley seat 3, the other end that synchronous rotation by the first sprocket wheel 4, the second sprocket wheel 12, the 3rd sprocket wheel 15 drives left and right chain is pulled upwardly hoisting frame 8, make hoisting frame 8 two ends synchronously increase by the guiding of roller 14 and elevating lever 1, the distance that is connected to spray boom on hoisting frame 8 and ground changes, and can spray insecticide to the crops of differing heights.

Owing to having adopted technique scheme, make the present invention have the scope of application wide, simple and practical, the advantage such as time saving and energy saving.
