On, the suspention connecting seat of the flexible draw piece of connection tractor is arranged on the support with transmission case movement.It is the utility model above
Basic technical scheme.
To make transmission case form the topology layout of more rational stress and smooth movement in frame, the utility model is in machine
Two slide bars of setting on frame, one is located on front side of frame flat-topped ridge slide bar before title, a slide bar after frame flat-topped ridge rear side title,
Sliding sleeve is fixed at the forward and backward edge for carrying the board-like seat of transmission case.
The preferable transmission case intermediate solid drive shaft drive gear of the utility model and the assembly method of casing and power transmission shaft are：Transmission
Power transmission shaft drive gear in case, which is fixed on one, to be had on the axle sleeve of internal splined hole, and axle sleeve both ends are arranged on casing with bearing,
Axle sleeve and the dynamic cooperation of power transmission shaft, realize power transmission shaft drive gear and the overall slidable fit on power transmission shaft of casing.
For energy control accurate stubble cleaner embedded depth, further improving for stubble cleaner of the present utility model is at frame both ends
Set by adjusting deep hydraulic cylinder and limiting deep sledge plate（Slide plate）The knife of composition rolls into native depth adjustment mechanism, therein to adjust on deep hydraulic cylinder
End is hinged in frame, and lower end and one end of the deep sledge plate of limit are hinged, and the other end for limiting deep sledge plate is hinged on hinged block in frame
On.
Good effect of the present utility model is：
1st, by setting up being slidably matched between the slide bar in frame, relative transmission case fixation sliding sleeve, frame and sliding sleeve
Between hydraulic cylinder it is flexible, stretch out the dynamic cooperation of the power transmission shaft and drive gear and casing in its transmission case of transmission case, it is real
Stubble cleaner is showed（Knife rolls）Transverse shifting and positioning with respect to tractor, change conventional tractor and drawn with stubble cleaner centering
Unique position relationship.By adjusting stubble cleaner with respect to tractor lateral attitude relation, it can realize and be ploughed in different hillside fields
In, keep tractor body need not tiltedly advance the steady traction between stubble cleaner, tractor, power waste is eliminated, without ploughing
The constantly observation of author and the direction of adjustment tractor, reduce physical demands, obtain hillside fields and level land identical farming efficiency.
, 2 adjust deep hydraulic cylinder and sledge plate realizes the accurate adjustment that knife rolls embedded depth by rack-mounted, and
And embedded depth does not change because of local relief, ensure that stubble-cleaning quality.
