Abstract
The utility model relates to a lifting mechanism, and particularly discloses a lifting mechanism of a boom sprayer. The lifting mechanism of the boom sprayer comprises a fixed stand of the boom sprayer, a spray boom fixing rack capable of moving up and down along a guide rail on the fixed stand, and a hydraulic cylinder and a cable which are fixed on the spray boom fixing rack, wherein the spray boom fixing rack is provided with a lower fixed pulley; the top of a cylinder rod of the hydraulic cylinder is provided with an upper fixed pulley; one end of the cable is fixedly arranged on the spray boom fixing rack, and the other end of the cable sequentially comes round the upper fixed pulley and the lower fixed pulley and is then fixedly arranged on the top of the stand of the boom sprayer by tension springs. The top of the stand is provided with the plurality of tension springs, the lower ends of the tension springs are connected together by a movable rod, and the cable is connected with the movable rod after coming round the lower fixed pulley. According to the lifting mechanism of the boom sprayer, the hydraulic cylinder is taken as power, the whole device is arranged on the spray boom fixing rack, and the stroke of the hydraulic cylinder is increased or decreased when a spray boom goes up or down, so that the lifting speed of the spray boom is delayed; furthermore, the hydraulic cylinder is controllable, so that the spray boom can be slowly and stably lifted.
Description
(1) technical field
The utility model relates to a kind of elevating mechanism, particularly a kind of boom sprayer elevating mechanism.
(2) background technology
Boom sprayer is a kind of for large-area crops field rotating medicine machinery, it comprises the spray boom that can slide up and down, after spray boom launches, can reach tens of rice, so it just require up and down slowly, steadily, in current elevating mechanism, also can not reach this kind of requirement.
(3) summary of the invention
The utility model, in order to make up the defect of prior art, provides a kind of boom sprayer elevating mechanism that makes slow, the steady lifting of spray boom.
The utility model is achieved by the following technical solution:
A kind of boom sprayer elevating mechanism, it is characterized in that: comprise fixed frame, the spray boom fixed mount moving up and down along the guide rail of fixed frame of boom sprayer and be fixed on hydraulic cylinder and the hawser on spray boom fixed mount, described spray boom fixed mount is provided with lower fixed pulley, the top of described hydraulic cylinder bar is provided with fixed pulley, described hawser one end is fixed on spray boom fixed mount, and the other end is successively walked around the frame top that is fixed on boom sprayer after fixed pulley and lower fixed pulley by extension spring.
Described frame top is provided with several extension springs, and the lower end of extension spring links together by motion bar, and the top of described hawser is connected with motion bar.
The beneficial effects of the utility model are:
Owing to having adopted hydraulic cylinder, be power, and whole device is arranged on spray boom fixed mount, when spray boom rises or declines, the stroke of hydraulic cylinder increases or dwindles, when the hurried increase of hydraulic cylinder travel, the power acting on hawser just increases, and the power namely acting in extension spring increases, and extension spring is extended, spray boom declines, and slows down the rising of spray boom; Otherwise power is dwindled, extension spring is shortened, and spray boom rises, and slows down the decline of spray boom, has so just delayed the rising or falling speed of spray boom, and because hydraulic cylinder has controllability, therefore can make slowly and reposefully lifting of spray boom.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is main TV structure schematic diagram of the present utility model.
In figure, 1 spray boom fixed mount, 2 fixed frames, 3 hydraulic cylinders, 4 hawsers, fixed pulley on 5,6 times fixed pulleys, 7 extension springs, 8 motion bars.
(5) embodiment
Accompanying drawing is specific embodiment of the utility model.As shown in Figure 1, this kind of boom sprayer elevating mechanism, the fixed frame 2 and the spray boom fixed mount 1 that comprise boom sprayer, fixed frame 2 is provided with guide rail, spray boom fixed mount 1 can move up and down along guide rail, on spray boom fixed mount 1, be fixed with hydraulic cylinder 3 and hawser 4, the cylinder masthead end of hydraulic cylinder 3 is provided with fixed pulley 5, on spray boom fixed mount 1, be also provided with lower fixed pulley 6, one end of hawser 4 is fixed on spray boom fixed mount 1, the other end is successively walked around fixed pulley 5 and is connected with a motion bar 8 with after lower fixed pulley 6, on motion bar 8, connect some extension springs 7, the other end of extension spring 7 is connected to frame 2 tops of boom sprayer, along with the change of hydraulic cylinder 3 strokes, drive 1 lifting of spray boom fixed mount, in this process, cushioning effect is played in extension spring 7, avoid causing 1 lifting of spray boom fixed mount too fast because hydraulic cylinder 3 output is too fast, thereby spray boom and facility have been protected.
Except technical characterictic described in specification, all the other technical characterictics are those skilled in the art's known technology.
Claims (2)
