The interior of the rotary cultivator does not need to be improved, and the rotary tillage stubble cleaner is high in universality, flexible in using and capable of reducing using cost.
Description
Technical field
The utility model relates to a kind of rotary tillage stubble-cutting machine of supporting hand tractor, belongs to hand tractor technical field.
Background technology
The rotovator of walking tractor matching is to be directly anchored on hand tractor with bolt, the connected left support arm of rotary blade roll shaft becomes a frame shape rectangle frame with right arm housing with chain case, change gear box and left arm housing, the moment producing to bear rotary tillage process.And the chain and sprocket driving device that engine power reaches side by transfer gear box drives rotary tillage rotor to rotate, at tractor, move ahead in process, be arranged on rotary blade on rotary tillage rotor and rotate and carry out operation.Although most rotovator can doublely be made stubble cleaner, but rotovator can only be applicable to the few field of weeds root stubble, and for the more field of weeds root stubble, rotovator is difficult for weeds root stubble to smash, and cause arable land resistance larger, even cause rotovator to occur stuck phenomenon.And be mostly connected with chain case with the stubble cleaner of walking rotary cultivator configuration, by power drive stubble cleaner, rotated and carried out stubble-cleaning, the stubble cleaner of this structure need to improve rotovator inside, not only complex structure, and versatility is poor, can increase user's use cost.
Summary of the invention
The purpose of this utility model is to provide that a kind of versatility is good without rotovator inside is improved, and uses flexibly, can reduce the rotary tillage stubble-cutting machine of the supporting hand tractor of use cost.
The utility model is that the technical scheme achieving the above object is: a kind of rotary tillage stubble-cutting machine of supporting hand tractor, it is characterized in that: comprise stationary knife mechanism and the rotary tillage rotor that rotary blade is housed, stationary knife mechanism comprises the connection end plate at two ends and is connected the fixing crossbeam of end plate with two, two connect end plate is arranged on respectively on the left support arm and transmission case body of rotovator by securing member, and on crossbeam, interval is fixed with three above perpendicular stubble-cleaning tool rests of putting, each stubble-cleaning knife is arranged on corresponding stubble-cleaning tool rest by securing member, stubble-cleaning knife and rotary blade all have square toothed cutting edge, and each stubble-cleaning knife and each the self-corresponding rotary blade formation sheared edge that matches.
The utility model is by two connection end plates, crossbeam and stubble-cleaning tool rest are connected to an overall structure, its stubble-cleaning knife is arranged on the perpendicular stubble-cleaning tool rest of putting, therefore can two connection end plates be arranged on respectively on the left support arm and transmission case body of rotovator by bolt, or remove from left support arm and transmission case, facilitate the installation of stationary knife mechanism, without existing rotovator interior is improved, versatility is good, when hand tractor previous operation, by power drive rotary blade, rotate and as knife section, and stubble-cleaning knife is done running and fixed blade, when ploughing, stubble-cleaning knife and the rotary blade formation sheared edge that matches is cut off weeds root stubble, solve rotovator arable land and occurred stuck phenomenon, be highly suitable for the more field of weeds root stubble, flexible and convenient to use, can reduce customer using cost.
