Abstract
The utility model relates to a crawler tractor part, concretely relates to crawler tractor turns to and goes up and down to merge operating device. A crawler tractor turns to and goes up and down to merge operating device, includes the control handle, pitches axle, supporting seat, steering arm, switching valve, lift control rod, lifting mechanism, supporting seat, switching valve, lifting mechanism fixed mounting are in the frame, fork axle swing joint is in the supporting seat, and the end of control handle is caught to the one of which end hinge, and other end fixed connection the lift control rod, the lift control rod links to each other with the lifting mechanism, the control handle middle part links to each other with the steering arm is articulated, the steering arm links to each other with the switching valve. The utility model discloses make and felt originally that busy the edge of a field operation became free and relaxed, do in an expert way, still improved farm work efficiency and farming effect to can reduce fuel consumption.
Description
Technical field
This utility model relates to a kind of crawler tractor parts, is specifically related to a kind of crawler tractor and turns to lifting union operation mechanism.
Background technology
The handling maneuver handle of the agricultural machinery such as existing crawler tractor and agricultural machinery and implement lifting control crank are all provided separately, each duty of each department.Machine, when farm work runs to the edge of a field, generally requires to simultaneously complete and turns to and agricultural machinery and implement two kinds of Job Operations of lifting, and tractor driver needs quickly to change between two control cranks, nervous and act hurriedly in a messy situation；Yi Fashengyin operation not in time and the agricultural machinery and implement that cause damage or the problem such as farming roughness descent.
Utility model content
The purpose of this utility model is in that to provide the crawler tractor of a kind of convenient and flexible operation to turn to lifting union operation mechanism.
For achieving the above object, this utility model provides following technical scheme: a kind of crawler tractor turns to lifting union operation mechanism, including control crank, fork shaft, supporting seat, steering arm, switching valve, lift control lever, lifter, described supporting seat, switching valve, lifter are fixedly mounted in frame, described fork shaft is movably connected in supporting seat, the end of the articulated control crank in its one end, the other end is fixedly connected lift control lever, and described lift control lever is connected with lifter；Being hinged and connected with steering arm in the middle part of described control crank, described steering arm is connected with switching valve.
As further technical scheme of the present utility model, described fork shaft is splined shaft, is connected by spline with supporting seat inside.
This utility model is by a set of non-interference link gear, original agricultural machinery and implement lift control lever and steering arm two bar are complex as a control crank, the horizontal fork shaft of level (fork shaft axial line and jaw hole axial line be 90 degree) is fixed in frame by supporting seat, and control crank employing bearing pin is arranged on the jaw on the right side of fork shaft.Control crank both can rotate before and after fork shaft axial line is made, and also can swing around the axial line of fork shaft jaw upper pin.When control crank seesaws, namely control lifting or the decline of agricultural machinery and implement；When control crank swings, namely control the left and right turn motion of machine.When farmland operation, the right hand of operator of farm machinery only need to handle an one control lever, do not need frequently hand-off between two one control lever parts, significantly reduce operation tensity and the labor intensity of tractor driver, the edge of a field operation making originally to feel busy becomes free and relaxed, handy, also improve field operation efficiency and farming effect, and fuel oil consumption can be lowered.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, this utility model provides a kind of technical scheme: a kind of crawler tractor turns to lifting union operation mechanism, including control crank 1, fork shaft 2, supporting seat 3, steering arm 4, switching valve 5, lift control lever 6, lifter 7, described supporting seat 3, switching valve 5, lifter 7 are fixedly mounted in frame, described fork shaft 2 is movably connected in supporting seat 3, the end of the articulated control crank 1 in its one end, the other end is fixedly connected lift control lever 6, and described lift control lever 6 is connected with lifter 7；Being hinged and connected with steering arm 4 in the middle part of described control crank 1, described steering arm 4 is connected with switching valve 5.
Described fork shaft 2 is splined shaft, is connected by spline with supporting seat 3 inside.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, being appreciated that when without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, amendment, replacement and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
