Description
Technical field
The utility model belongs to the technical field of farm machinery, and in particular to a kind of rice field folding rotary cultivator.
Background technique
Rotary cultivator is the cultivation machinery for completing to plough, harrow operation with tractor.Because it is strong with hack ability, ploughs rear ground
The features such as table is flat, and be widely used；It can shred simultaneously and be embedded in earth's surface root stubble below, make convenient for seeder
Industry provides good kind of bed for later period sowing.
Currently, the workpiece of rotary cultivator mainly includes rotary tillage rotor and uniformly configures by bull helical several on the market
Native blade is cut, driven by tractor motive power output shaft by transmission device, normal revolution is 190~280 revs/min.Wherein, knife
The direction of rotation of roller is usually consistent with the direction of tractor wheels rotation, cuts native blade and cuts soil layer from the front to the back, and by soil block
It throws on housing and planker rearwardly and upwardly, is allowed to further be crushed.When rotor cuts soil and throws soil, reaction force of the soil to rotor
Help that unit is pushed to advance, thus required tractive force very little when horizontal rotary tiller operation, it can even be pushed sometimes by rotor
Unit advances；Scalpriform knife, tulwar, right angle knife and curved knife can be divided by cutting native blade.Wherein, scalpriform knife front end is relatively narrow, has preferably
Ability of burying, energy consumption is small, but easily twines grass, is chiefly used in the few vegetable garden of weeds and garden；The curved cutting edge of tulwar has sliding cutting
Grass roots and straw winding are easily cut off in effect, are suitable for paddy field farming.
And following problems are primarily present for current rotary cultivator:
(1) existing rotary cultivator rear portion is typically equipped with plate, and field face of the plate for rice field is smooth, but loads onto plate
Afterwards, on the one hand, the folding of plate is inconvenient, and plate is caused to will affect the normally travel of rotary cultivator, and on the other hand, plate is to field
Face carry out support it is flat during, plate is easy to damage by larger frictional force, and plate is also bad to the flat effect of the support in field face；
(2) front end of existing rotary cultivator is respectively arranged with colter, and colter is used to scoop up in soil, then cooperates on rotary tillage rotor
Native blade is cut to cut off soil, to achieve the purpose that loosen the soil, but since the soil that often colter scoops up is higher and thicker,
Native blade cannot be usually cut in rotary cultivator cultivating procedure sufficiently to cut off, it is therefore, ineffective to loosening the soil for soil, need rotary tillage
Machine carries out farming repeatedly, and farming efficiency is lower.
Utility model content
In order to solve the above problems existing in the present technology, the utility model aim is to provide a kind of rice field with foldable
