Description
Technical field
The present invention relates to a kind of rotary blade more particularly to a kind of micro- coulters；Belong to agricultural machinery.
Background technique
Rotary tillage cutter can be divided into mini-tiller rotary blade and large-scale rotary cultivator rotary blade, the two installation according to equipment size
Mode is different.Mini-tiller rotary blade（Referred to as micro- coulter）Generally it is installed on six square shafts by two bolts hole, and large-scale rotation
The machine of ploughing usually adopts single bolt hole installation with rotary blade；As it can be seen that micro- coulter and rotary blade are equal in terms of applicable situation and manufacturing process
It is distinct.Therefore, the rotary blade that large-scale rotary cultivator uses does not adapt to mini-tiller substantially.
It is improved currently, micro- coulter is widely used and is substantially according to incision nineties section formula rotary blade, although structure
It is fairly simple（Knife face uses planar structure）, but hack effect is poor；It is big, easy to harden to be difficult to adapt to viscosity, based on yellowish soil
Hills or mountain soil.For this purpose,
Authorization Notice No. discloses entitled " a kind of for gasoline engine type mini-tiller for the patent of invention of " 102090165 B of CN "
Dry land blade " the micro- coulter in nonirrigated farmland, which is substantially the micro- coulter product of existing market mainstream.Due to the knife face of the patented product
For two-dimensional space curved surface, thus for its hack effect of clayed soil, throw native effect not yet be improved significantly.
Summary of the invention
In view of the above defects of the prior art, the present invention is intended to provide a kind of nonirrigated farmland clayed soil curved surface is micro- cultivated
Knife, micro- coulter can obviously improve the hack of clayed soil and throw native effect.
To achieve the goals above, the present invention uses following technical scheme：It includes flat knife handle, and the one of the knife handle
End extends forward and forms the cutter hub that side has single side sword, and the single side sword is the curvilinear structures being bent outwardly；The cutter hub
Space curved surface structure made of being successively smoothly connected as positive dissection, changeover portion, lateral incision section, single side sword successively by with positive dissection pair
The corresponding transitional edges of the positive cutting blade and changeover portion answered, lateral incision sword corresponding with lateral incision section are smoothly connected；Cutter hub is along length side
To be gradually curved tilt and form the curved surface that angle is β, cutter hub in the direction of the width along cutter hub length trend gradually crimp and
Form the curved surface that angle is α.
Cutter hub is bent to the side knife surface for offering single side sword, and curved angle β is 121~124 °；Cutter hub is to opening up
There is a side knife surface of single side sword to crimp, curling angle α is 10~30 °；Cutter length is 280~330mm, knife face width is 30
~40mm, knife face are 225~245mm with a thickness of 5~6mm, cutter radius of gyration R.
Compared with the prior art, the present invention is by adopting the above-described technical solution, be changed to three-dimension curved surface structure for knife face；
Therefore the advantages that native effect and hack effect are good, tilling depth is big, long service life is thrown.It makes a concrete analysis of as follows：
1）When cutter hub cuts soil, soil can face up flowing relative to cutter hub；And cutter hub front is three-dimensional space introversion
Face structure, therefore soil will receive the centripetal force of negative camber offer and form lateral sliding, curling, thus a more hack
Process improves the hack effect of clayed soil.
2）Due to increasing cutter radius of gyration R（The radius of gyration of conventional tool is 195mm）, therefore soil can be increased and hit
Hit initial velocity.In addition, due to the knife face for using three-D space structure, although cutter total length greatly increases, cutter revolution
The incrementss of radius are only 30~50mm（If cutter radius of gyration incrementss are more than 50mm, the matched power of mini-tiller is obvious
It is insufficient；If cutter radius of gyration incrementss are less than 30mm, hack is effect improved unobvious）
3）Due to knife face use three-dimensional space curved surface structure, and bending curvature and curling curvature with cutter the radius of gyration increase
It incrementally increases greatly（Bending degree increases）, therefore the centrifugal force that not only soil can be made to be subject to also is stepped up, but also can
It avoids cutter from causing stress and the moment of resistance increased dramatically because of unexpected bending, be broken, extends cutter life.

In figure：Knife handle 1, positive cutting blade 2, transitional edges 3, cutter hub front 4, lateral incision sword 5, the cutter hub back side 6, lateral incision section 7, changeover portion 8, just
Dissection 9, knife spine 10, bolt hole 11, mounting hole 12.
Specific embodiment
The invention will be further described with specific embodiment with reference to the accompanying drawing.
As shown in Fig. 1~7：Knife handle 1 is in plane tabular structure, offers semicircular mounting hole 12, the installation on knife handle 1
Respectively there are a bolt hole 11 in the two sides in hole.One end of knife handle 1 extends forward and forming side has knife with single side sword, the other side
The cutter hub of back 10, the single side sword are the curvilinear structures being bent outwardly, and knife spine 10 is aduncate curved-surface structure.The cutter hub
Space curved surface structure made of being successively smoothly connected as positive dissection 9, changeover portion 8, lateral incision section 7, single side sword successively by with tangent
9 corresponding positive cutting blades 2 of section and the corresponding transitional edges 3 of changeover portion 8, lateral incision sword 5 corresponding with lateral incision section 7 are smoothly connected.Knife
Body is gradually curved tilting along its length and forms the curved surface that angle is β（I.e. for cutter hub also closer to knife handle 1, bending curvature is smaller；
Further away from knife handle 1, bending curvature is bigger）, cutter hub gradually crimps along the length trend of cutter hub in the direction of the width and forms angle
For the curved surface of α（I.e. it is smaller to crimp curvature also closer to knife handle 1 for cutter hub；Further away from knife handle 1, it is bigger to crimp curvature）.Wherein, it presss from both sides
Angle beta is 121~124 °, angle α is 10~30 °, and cutter length is 280~330mm, knife face width is 30~40mm, knife face is thick
Degree is that 5~6mm, cutter radius of gyration R are 225~245mm.
In order to improve centrifugal force that soil is subject to, increase and get rid of soil and hit initial velocity, improve hack effect, cutter hub is along length side
Two-dimensional Surfaces are formed to being bent to the side knife surface for offering single side sword（I.e. cutter hub front 4 is negative camber, the cutter hub back side 6 is
Positive camber）；For the ease of soil lateral sliding, curling, hack effect is improved, cutter hub is in width direction to offering single side sword
One side knife surface crimps and forms three-dimension curved surface（I.e. cutter hub front 4 is negative camber, the cutter hub back side 6 is positive camber）.
