Description
Technical field
The utility model belongs to agriculture and forestry machinery technical field, more particularly to a kind of ground profiling scythe.
Background technology
Grass in orchard generally wants periodic cleaning, weeding to need to ensure the height for the stubble left, is both avoided that weeds and fruit tree in this way
Nutrient is fought for, is also avoided that the soil erosion caused by weeding, nutriment reduction and ecological balance problem etc..
It is general using 5~10cm of mechanical mowing mode toothing in order to avoid orchard soil erosion problem.Due to China various regions
The difference of topography and geomorphology, some regional soils are more smooth, and the very smooth orchard of landform, toothing is simple, and general grass trimmer can win
Appoint.For when the poor hillside orchard of those flatness is mowed, common grass trimmer is then helpless, does not adapt to these
The place of hypsography, operation effectiveness is very poor, and efficiency is not also high.Although there is some profiling grass trimmers, that can only be a certain
Imitative landform is carried out on direction, and it is higher, relatively low or cut not clean problem to be easy to cause toothing.For this reason, it may be necessary to a kind of profiling effect
Grass trimmer more thoroughly goes to improve these situations.
Some citrus orchards are exactly to be in gentle slope landform and hilly country, and common grass trimmer is difficult to effectively mow.Backpack is cut
Careless machine is semi-mechanization, and people is needed to bear operation, and mowing efficiency is relatively low with respect to direct-connected mower, and is unable to high intensity work
Make, is not suitable for the production of large area orchard.Although pesticide weeding saving of work and time, side effect is also very big, on the one hand be easy to cause water
Fruit pesticide residue, on the other hand will also result in ecological problem.So still needing a kind of grass trimmer of mechanization, it is allowed to adapt to one
The not high landform of a little flatness, such as Yichang citrus orchard landform.
Utility model content
The utility model provides a kind of limitation breaking through topography and geomorphology, can not only cut off the grass of low relief area, also can
The landform of some fluctuatings is adapted to, and makes the profiling that cutterhead can not only be in one direction, it also can be imitative on the ground of surrounding profiling
Shape scythe.
