Abstract
The utility model provides a rotary cultivator or a rotary sowing cultivator with long and short blades arranged at intervals. The knife shaft of the rotary cultivator or the rotary sowing cultivator is arranged with a rotary cultivation long blade and a rotary cultivation short blade, both of which are arranged at intervals. The short blade is arranged in the middle of the long blade, and the front short blade and the rear short blade are polar apart, knife points point oppositely. Besides, the short blade and the long blade are positioned with equal distance at the opposite sides of the long blade. The long blade of the utility model is special for rotary cutting of soil, and the length of the long blade as well as the rotary arc can be completely designed in line with the demand of a deep tillage. In comparison, the short blade is not involved in the rotary cutting of soil and only serves to break soil. Under the circumstance of not increasing the load of the main set, the short blade can break soil when the long blade carries the rotary cultivation of soil, just like killing two birds with one stone. The utility model only improves the knife shaft of the rotary cultivator or the rotary sowing cultivator; and has the advantages of easy operation and strong practicability.
Description
Technical field
The utility model relates to agricultural machinery technological field, the rotovator that specifically a kind of length cutter makes up alternately, rotary tillage sower.
Background technology
Now, the rotovator that China generally uses in vast rural area, the operation principle of rotary tillage sower all are the cutter shaft rotations that driven rotovator (rotary tillage sower) by engine, the rotary blade rotary tillage soil on the cutter shaft, and reaching digs inserts the purpose of planting.Usually, in order to reach certain rotary tillage degree of depth, rotary blade must have enough length; In order to make the native location after the rotary tillage have certain percentage of damage, then must increase the density that rotary blade is installed on cutter shaft.Yet the length of the rotary blade of installing and quantity are to be subjected to main engine power to limit on the cutter shaft.As the density that increases existing rotary blade can make main unit load excessive; As shortening the length of rotary blade, the rotary tillage degree of depth does not reach the requirement of plantation again, and present rotovator can't solve the conflicting problem of the rotary tillage degree of depth and garrulous soil rate.
Summary of the invention
The utility model is at the above-mentioned topic of sending one's regards to, rotovator, rotary tillage sower that long and short cutter makes up have alternately been proposed, purpose is under the prerequisite that does not increase rotovator original host load, with the rotary tillage degree of depth in rimmer knife enforcement solution soil, implements to improve the percentage of damage of soil with short sword.
Technical solution of the present utility model
The utility model is equipped with rotary tillage rimmer knife and short sword on the cutter shaft of rotovator, rotary tillage sower, and long and short cutter alternately.
The beneficial effects of the utility model:
(1) rimmer knife of the present utility model carries out the rotary-cut of soil specially, can require design cutter length and revolve arc according to deep ploughing fully; And short sword does not participate in the rotary tillage to soil, only is used for broken soil, can not increase the load of main frame again, thereby makes the rotary tillage of soil and garrulous soil rate can both reach perfect condition.
(2) the utility model only improves the cutter shaft of rotovator and rotary tillage sower, and simple, easy row can solve practical problem, and is practical.
Description of drawings
Accompanying drawing is the structural representation of long and short cutter aggregate erection alternately on the utility model cutter shaft
Embodiment
Rimmer knife 2 and short sword 3 are installed on the cutter shaft 1 of the alleged rotovator of the utility model, rotary tillage sower, short sword is installed in the centre position of rimmer knife, the pointing direction that forward and backward short sword orientation differs 180 degree, point of a knife is opposite, forward and backward short sword is again equidistant reverse each other both sides of same rimmer knife that are positioned at, in addition: described short sword can be a straight knife, also can be for revolving arc cutter (not shown).
The regular permutation and combination structure of length cutter of the present utility model as shown in the figure.
In the use of the present utility model, in rimmer knife rotary tillage soil, short sword just can broken soil, kills two birds with one stone.
Claims (2)
1. rotovator, the rotary tillage sower that the length cutter makes up alternately comprises rotary ploughing cutter shaft (1), it is characterized in that: rotary tillage rimmer knife (2) and short sword (3) are installed on the cutter shaft (1), and long and short cutter alternately.
2. rotovator, rotary tillage sower that a kind of length cutter according to claim 1 makes up alternately is characterized in that: described short sword can be a straight knife, also can be for revolving the arc cutter.
