Abstract
The utility model relates to a high-low speed rotary cultivator, in particular to a grading machine especially for the tractor with back power output, wherein a gear box is arranged at center, connected with a side transmission case via a universal joint, to change speed at high and low shifts, while under high speed, the utility model can rotationally cultivate on soft ground or plough stubble, and under low speed, the utility model can rotationally cultivate on hard ground. The utility model can resolve the single-speed problem of prior art, which can realize speed-variable rotary cultivation, to improve working efficiency, with better structure versatility, simple operation and easy application.
Description
Technical field
The utility model relates to the high low speed rotovator of a kind of back output, be farmland operation facility with double speed rotary tillage and stubble-cleaning, cutter shaft adopts two kinds of rotary speeies, low speed is used for the harder plot of rotary tillage soil property, be used for installing the plot of pine of cutterhead stubble-cleaning or rotary tillage soil property at a high speed, can not only finish the farmland rotary tillage and also can carry out the crop stubble-cleaning.
Background technology
At present, known back power is exported the less of the fast operation of rotary tillage function height, and, most idler gear transmission, idler gear casings of adopting.The side gearbox is installed, and makes that a side is heavier, and a side is lighter, need carry out balance, and balance weight is installed.The double speed rotovator of middle speed change transmission is also arranged, and during the rotary tillage operation, balk in the centre, though the leakproof plowing device is installed, practicality is relatively poor, can not satisfy agriculture requirement, and its purposes also has unicity.
Summary of the invention
The purpose of this utility model designs a kind of simple in structure exactly, rotary tillage machinery that can speed change, and it is that speed change gear is installed in the middle of frame, high speed and two kinds of speed of low speed are arranged, handle just energy conversion rotary tillage speed of speed change gear, easy to use, the production efficiency height, provide a kind of and can carry out farming the harder plot of soil property, the also rotary tillage machinery that can carry out farming to the softer plot of soil property, and, the stubble-cleaning cutterhead is installed, adopt top gear, also can carry out the crop stubble-cleaning.
The purpose of this utility model is achieved in that on frame, the middle gearbox of installing, dynamic power shaft, small conical gear, large conical gear, one, two in gearbox have clutch gear, transmission meshing gear respectively on one and two, high gear, low-speed gear.On middle gearbox, gear lever is arranged, the gear change speed by in the gear lever manipulation gearbox then, is connected transfer motion power by Hooks coupling universal coupling with the transmission case of side, drives the rotary ploughing cutter shaft rotation by transmission case.During work, can obtain at a high speed and two kinds of speed of low speed, be used for softer plot of soil property or stubble-cleaning at a high speed, low speed is used for the rotary tillage of hard place piece,
Owing to adopt such scheme, overcome the drawback of the speed simple function of rotovator that present back power output tractor drives or stubble cleaner, middle gearbox, side driving box has solved the speed change problem of back driving rotary cultivator, during use, only need to handle speed change gear, just can carry out velocity transformation very easily, easy to use, reliable, applicability is good, thus solved the problem of a tractor serves several purposes.
