Description
Technical field
This invention relates to a kind of pendulous device of brush saw, belongs to the brush saw technical field of agriculture and forestry machinery.
Background technology
The brush saw that is driven by the tractor outputting power mainly is made of hood, gear-box, transmission mechanism and cutter shaft assembly etc., and the tractor outputting power drives the cutter shaft rotation through gear-box and transmission mechanism, is used to cut shrub and mowing etc.Brush saw by power traction all is connected with tractor by rearmounted trifilar suspension at present.Because the hanging position up and down on the brush saw is a fixed structure, brush saw working width position in operation process is unadjustable, the working width position of causing brush saw can not lateral adjustments with respect to the hanging position of tractor, not only the brush saw working width is fixed, and the operating area also can only be some broad areas that tractor is advanced, and job area is more fixing.Common level of the cutter shaft of brush saw or vertical setting the in addition, when brush saw with after tractor is connected, brush saw is can't be tilting, so for extreme terrains such as irrigation canals and ditches, levee slope and espaliers, brush saw can't carry out operation.
Summary of the invention
The purpose of this invention is to provide a kind ofly under the fixing situation of tractor trifilar suspension, in operation process, can conveniently change and increase the working width of brush saw, and brush function deflecting slant is put the pendulous device of the brush saw that carries out the cutting operation requirement.
The present invention is that the technical scheme that achieves the above object is: a kind of pendulous device of brush saw, it is characterized in that: comprise body, deflection mechanism, swing mechanism and hanger bracket, described swing mechanism is by the left swing arm of rocker before being hinged on and rocker both sides, back and the quadric chain that right swing arm constitutes, the two ends of swing oil/cylinder are hinged on the inboard of left swing arm and right swing arm respectively, and an end of hanger bracket is connected on the preceding rocker; Described deflection mechanism comprises deflection oil/cylinder, deflection connecting rod and yawing axis, the yawing axis that biasing is fixed on the body sidepiece is rotatably installed on the rocker of back, the deflection connecting rod that is hinged on the rocker of back is connected with an end of deflection oil/cylinder, and the other end of deflection oil/cylinder is hinged on the body that is in reverse to back rocker one side.
The quadric chain of the left swing arm of rocker and rocker both sides, back and right swing arm formation before swing mechanism of the present invention adopts and is hinged on, and swing mechanism is fixedlyed connected with tractor by hanger bracket, swing mechanism is connected with the body of brush saw again by deflection mechanism simultaneously, because deflection mechanism is positioned at the body sidepiece, so when the swing oil/cylinder that is hinged on left swing arm and right swing arm inboard is longitudinally done stretching motion, meeting drives deflection mechanism and body carries out sidesway with respect to the tractor hitch point in horizontal plane, the convenient operating position that changes and adjust brush saw.Simultaneously in cutting process, by swinging the continuous flexible start of oil/cylinder, increase the working width of brush saw, so increased substantially cutting efficiency, be not only applicable to commodiously with operation, and can be in the unapproachable bending of tractor carry out operation in the narrow or barrier barrier zones such as tree, withered tree.Yawing axis and linkage in the deflection mechanism of the present invention are rotationally connected, deflection mechanism and linkage can be relatively rotated, this yawing axis is to fixedly connected with body, therefore can rotate around the center of rotation axis of back rocker by the flexible drive deflection mechanism and the body of deflection oil/cylinder, make brush saw tilting in addition can be vertical and ground carry out cutting operation, owing to can multi-facetedly carry out operation, can satisfy the job requirements of extreme terrains such as espalier, irrigation canals and ditches, levee slope.The present invention is in the brush saw operation process, can not only change and adjust the brush saw working width, and can also improve the brush saw working width, operating flexibility, convenient, can in the operating area that tractor can't arrive, carry out operation, increase substantially the brush saw operating efficiency, can satisfy the different work requirement.
