Description
The utility model is the overhead Height Adjustable Miniature cultivator used on higher of a kind of frame, belongs to agricultural machinery technological field.
In recent years, the tiller that people use is owing to adopt single-row walking, the tooth of the driving and driven gear on the crawler belt and track chain are clearance meshing, poor stability during the farming walking, easily lodging, tractor driver's labour intensity is big, other parts ground clearances on engine and the frame are little, and can not adjust, be unsuitable for paddy-field-working, be difficult for popularizing.
The purpose of this utility model provides a kind of good stability, the adjustable Miniature cultivator used on higher of frame ground clearance.
The purpose of this utility model is achieved in that engine places the preceding upper end of frame, flywheel on the engine links to each other with clutch by belt, the friction plate internal spline of clutch and transmission input shaft spline engagement, the speed changer output wheel links to each other by driving chain with sprocket wheel on the driving gear shaft, the tooth of driving gear and the engagement of the roller on the crawler belt, before preceding driven gear and back driven gear place crawler belt, the rear end, roller engagement on its tooth and the crawler belt, an end of driven gear adjusting yoke before preceding driven gear is fixed on, before the other end of driven gear adjusting yoke be fixed in the lifting garden arc groove on the frame, back driven gear is fixed on an end of back driven gear adjusting yoke, the other end of back driven gear adjusting yoke is fixed in another lifting garden arc groove on the frame, left righting wheel and right righting wheel are equipped with in preceding driven gear and driven gear both sides, back, ploughshare is contained in the body front end, rotary blade can be contained in the body front end also can be contained in the speed changer back lower place, and operating mechanism is contained in the body back upper place.
Before the both sides of driven gear and back driven gear can be respectively or left righting wheel and right righting wheel be housed simultaneously;
Have two bar shape trench holes on the forward and backward driven gear adjusting yoke, its groove width and each tie down screw external diameter sliding fit;
Lifting garden arc groove on the frame is two, its groove width and each tie down screw external diameter sliding fit.
Left and right righting wheel can directly be fixed on the forward and backward driven gear shaft, also can be installed on the forward and backward driven gear shaft by bearing.
The utility model compared with prior art has following advantage:
1. adorned left and right righting wheel owing to increasing in the driven gear both sides, made it the good stability of farming walking, be difficult for lodging, tractor driver's labour intensity reduces.
2. increased elevator, made frame, be suitable for paddy field and different farmland operations overhead apart from adjusting.
3. this body is long-pending little, in light weight, cost is low, is applicable to the use of rural area patch farming and ungetable mountain area, is convenient to popularize.
