Utility model content
The purpose of this utility model is just to provide one and had both met operator custom, handles the lightest, comfortable land leveller operating mechanism.
Solution of the present utility model is such that
A kind of land leveller operating mechanism, including rocking bar and valve rod, the rocking bar on each road includes steel bushing, the nonmetal axle sleeve being arranged in steel bushing hole, described steel bushing surface is radially provided with the body of rod and rocking arm, described nonmetal axle sleeve inner hole sleeve is connected to horizontally disposed transverse axis and forms swinging structure, and the rocking bar of multichannel is socketed on transverse axis side by side；The fixing axle parallel with transverse axis it is provided with below described transverse axis, described fixing axle is socketed with the shifter of multichannel side by side, the shifter on each road has been radially arranged master arm and passive arm, its master arm passes through pull bar, oscillating bearing connecting rocker arm, and its passive arm is connected with valve rod by oscillating bearing；Being fixed with the first nonmetal axle sleeve in described shifter hole, the first nonmetal axle sleeve inner hole sleeve is connected to fixing axle and forms swinging structure.
More specifically technical scheme also includes: the described rocking bar body of rod is bending structure, and the plane that two bending axis are formed is vertical with steel bushing axis.
Further: described rocking bar body of rod length is more than rocking arm length, constitute reinforcement structure.
Further: adjacent rocking bar body of rod wrap direction is the most in the same direction so that after assembling, between the adjacent rocking bar body of rod, shape is at a certain angle.
Further: described pull bar two ends are provided with bending section, its two ends bending section axis is parallel to each other, and three sections of straightway axis are the most at grade.
Further: to have screwed hole on rocking arm free end, screwed hole axis is parallel with steel bushing axis.
Further: between master arm and the passive arm of described shifter, shape is at a certain angle.
Further: the master arm of shifter and passive arm have screwed hole, and screwed hole axis is parallel with shifter steel bushing axis.
Further: described rocking bar body of rod upper end connects handle ball.
The utility model has the advantages that each independent rocking bar distance Relatively centralized, the health of driver is made without bigger action just can operate each rocking bar, it is also possible to handles simultaneously and does not interfere with each other mutually between several rocking bar and each rocking bar.Owing to rocking bar is force-increasing mechanism and fall friction design, driver is when handling, and manipulation dynamics is obviously reduced, and reduces the manipulation fatigue strength of driver so that human engineering is well embodied.
