Abstract
The utility model discloses a kind of double disk opener to be coupled bionical disc structure, it arranges wedge shape projection and spherical convex closure in the disc surfaces of double disk opener, wedge shape projection and spherical male wrap in disc surfaces and distribute alternately ringwise, total multilayer, the wedge shape of adjacent layer is protruding relative with spherical convex closure; In the process of plough trench digging, wedge shape projection of the present utility model and spherical convex closure coupling biomimetic features can break the continuity of the moisture film formed when soil contacts with disc surfaces, lower the cohesive force of soil, thus reduce soil to the adhesion of disk, reduce soil to the resistance of plough, improve trench digging quality, reduce the consumption of fuel.
Description
Technical field
The utility model belongs to agricultural mechanical field, total double disk opener after relating to, and particularly a kind of double disk opener is coupled bionical disc structure.
Background technology
Double disk opener is widely used in the soil-engaging component on grain seeder and intertillage crop precision planter, and it is poor to go for whole ground condition, the high-speed job that soil moisture is large.But due to reasons such as adhesions in cultivating procedure, cause that working resistance is large, soil disturbance is large, therefore optimize the structure of plough, reduce farming and adhere to, reduce soil resistance the trench digging lifting of quality, the reduction of energy consumption are significant.
The disk of common double disk opener is plane, can capillary force and viscous force be caused due to contact interface continuous print water ring or moisture film and cause adhesion when contacting with soil, the disturbance of soil can be increased like this, reduce the quality of trench digging, affect the output of crop, cause the increase of tractive resistance simultaneously to a certain extent.
Be that the Morphology and structure of the design soil-engaging component of research means makes a breakthrough to reduce soil to the adhesion of soil-engaging component and resistance with bionics.The ejector dozer gone out with the Non-smooth surface form Design of soil organisms surface and bionics plow moldboard, have the effect well reducing soil adhesion, reduce soil resistance through experimental verification.Field test results shows that bionics plow moldboard can reduce plowing resistance 15% ~ 18%, saves oil consumption 5.6% ~ 12.6%, and has good de-soil nature energy.
Summary of the invention
The purpose of this utility model is to provide a kind of double disk opener and is coupled bionical disc structure, and the bionical disc structure of this coupling can reduce soil adhesion, reduces trench digging resistance, reduces fuel consumption, reach energy-conservation object.
The carinate protuberance of pangolin scale and the head of dung beetle these two kinds of structures protruding, belong to Geometric nonsmooth surface, reduce adhesion when these surface textures can make pangolin and dung beetle move in soil, even do not adhere to, but also its resistance moved in soil can be reduced.The utility model is according to bionics principle, and the two kinds of structures that are coupled are designed to a kind of Novel ditching device disk.
The utility model arranges wedge shape projection and spherical convex closure in the disc surfaces of double disk opener, and wedge shape projection and spherical male wrap in disc surfaces and distribute alternately ringwise, total multilayer, and the wedge shape of adjacent layer is protruding relative with spherical convex closure; T is the thickness of disk; H1 is the height of wedge shape projection, and the spherical crown height of L1 to be the length of wedge shape projection: H2 be spherical convex closure is the spherical crown diameter D2 of spherical convex closure; A is the angle between directions of rays two projection; Wherein H1=T, L1=D2, H2=7% ~ 13%D2, A=7.2 ° ~ 12 °.
The utility model passes through the vibrational power flow of wedge shape projection and spherical convex closure and wedge shape is protruding and the combination of spherical convex closure parameter, and disk would not produce adhesion, reduces the trench digging resistance of double disk opener.
The beneficial effects of the utility model are: when double disk opener ditching operation, disk and soil close contact, protruding and the spherical convex closure of wedge shape due to disc surfaces makes the contact surface of soil and disk not easily form continuous print moisture film, such adhesion strength will keep lower level, and disk would not produce adhesion.Meanwhile, so also can reduce the resistance of trench digging, improve the quality of work, reduce the consumption of fuel.
