Description
Technical field
The present invention relates to a kind of subsoiling colters on agricultural machinery, and in particular to a kind of bionical drop resistance visbreaking colter of coupling,
Belong to agricultural machinery technological field.
Background technique
Plough be with dig loosen the soil for major function and having, the soil cultivating machine of hack effect.Colter is the most important of plough
Component part decides the depth and effect loosened the soil.Existing colter is taken a fancy to from the appearance is substantially similar to spade shovel head, generally
The defects of excessive, colter serious wear that there are tractive resistances, slowly drained soil adherency are seriously, subsoiling effect is undesirable.Tradition is improved
Method is mainly to increase the quantity of colter, to increase Subsoiler efficiency；Subsoiling active traction is improved, to overcome colter to be held
The resistance received；A part of area among colter is removed, to reduce adherency of the slowly drained soil to colter.Though the above tradition improved method
So reduce colter resistance to a certain extent, reduce the adherency of slowly drained soil, but there is also some problems: operating cost
Greatly, economy is bad；It loosens the soil not exclusively, subsoiling effect is unobvious；Colter service life substantially reduces.Therefore, one kind is designed
Operation resistance can be effectively reduced, the colter of reduction soil adhesion has a very important significance.
Summary of the invention
The object of the present invention is to provide a kind of bionical drops of coupling to hinder visbreaking colter, for digging in agricultural tillage, loosens the soil
And hack.
Soil animal (earthworm, mole cricket, dung beetle, ant etc.) passes through evolution in 1 years, creates it and adapts to the excellent of environment
Elegant ability not only makes it obtain minimum excavating resistance in soil mining process, and has the function of excellent de- soil drop resistance,
Always agricultural machinery improves performance, improved method imitates object.Research shows that soil animal (has including pangolin etc.
Have other animals of stronger soil data mining duty) have the function of very strong reducing adhesion resistance mainly due to following one or more factors
Coupling forms: (1) animal body surface has the specific forms such as Non-smooth surface, dense cilium；(2) animal body surface soil-engaging component has
Particular geometries are conducive to drag reduction；(3) animal body surface has stronger hydrophobic substance or low-surface-energy feature；(4) animal
Body surface can secrete special liquid, play lubricating action etc..
Mentality of designing of the invention derive from Oriental burmeister front foot pawl toe, according to front foot pawl toe geometry and function,
Devise the bionical touching soil pawl toe of colter.On this basis, the colter surface with bionical pawl toe is coated into one layer of polytetrafluoroethyl-ne
Ene coatings.
The present invention includes colter main body and bionical pawl toe, and colter surface coats one layer of polytetrafluorethylecoatings coatings, bionical pawl toe
Monomer cross-sectional profiles are made of three curves, and wherein x is abscissa, and y is ordinate:
First curve meets: y=0.09375x2-0.125x+3；Wherein: 0≤x≤8；
Second curve meets: y=0.125x2-x+8；Wherein: 0≤x≤8；
Third curve meets: x=0；Wherein: 3≤y≤8.
The bionical pawl toe monomer thickness be 50mm, bionical pawl toe equidistantly distributed in the vertical center line of colter concave surface,
It is divided into 50mm, most common cast steel in bionical pawl toe material selection agricultural machinery, bionical pawl toe and colter concave surface on-link mode (OLM) are welding.
The polytetrafluorethylecoatings coatings are coated with a thickness of 30 μm using chemical vapour deposition technique (CVD).Polytetrafluoroethylene (PTFE) is typical
Super-hydrophobic coat, adhesiveness is good, it only at high temperature (usually 200 degrees Celsius or more), can just volatilize noxious material.This
The operating environment temperature of invention is 30 degrees Celsius hereinafter, so the case where there is no coating volatilization noxious materials.Both will not
Pollution is generated to soil constituent, subsequent crop cultivation will not be had an impact.
The beneficial effects of the present invention are:
It is imitative that the present invention is designed and processed a kind of novel coupling using bionical pawl toe and polytetrafluoroethylene (PTFE) super-hydrophobic coat
Raw drop resistance visbreaking colter, the present invention are a kind of optimization and improvement to traditional colter.The present invention can efficiently reduce colter touching
The resistance obtained when native, further, the super-hydrophobic coat substantially reduce the adherency of viscous wet soil earth, avoid colter because making
Industry resistance is excessive or soil adhesion seriously reduces efficiency, and then reduces its service life.The bionical colter technique letter of coupling
It is single, low in cost, effect is obvious, to improve colter service efficiency be of great significance.

Specific embodiment
It please refers to shown in Fig. 1 to Fig. 7, the present invention is made of colter main body 1 and bionical pawl toe 2, colter surface coating one
Layer polytetrafluorethylecoatings coatings 6, bionical 2 monomer cross-sectional profiles of pawl toe are made of three curves, and wherein x is abscissa, and y is vertical sits
Mark:
First curve 3 meets: y=0.09375x2-0.125x+3；Wherein: 0≤x≤8；
Second curve 4 meets: y=0.125x2-x+8；Wherein: 0≤x≤8；
Third curve 5 meets: x=0；Wherein: 3≤y≤8.
Bionical 2 monomer thickness of pawl toe is 50mm, and bionical pawl toe 2 is equidistant in 1 concave surface vertical center line of colter main body
Distribution is divided into 50mm, and bionical 2 material of pawl toe is cast steel, and it is to weld that bionical pawl toe 2, which connect the mode of connecing with 1 concave surface of colter main body,.
The polytetrafluorethylecoatings coatings 6 with a thickness of 30 μm, coated using chemical vapour deposition technique (CVD).It is described
Polytetrafluorethylecoatings coatings 6 will not volatilize in the present embodiment operation process noxious material the case where.
Working process and principle of the invention:
The present invention is digging, in operation of loosening the soil, and it is the bionical pawl toe monomer that colter touches native position at first, acts on class
The pawl toe being similar on Oriental burmeister front foot can effectively be split soil along the smallest point of penetration of resistance, be digged, and be completed first
Secondary touching soil, and then the concave surface of entire colter main body carries out secondary touching soil, soil at this time has had been provided with certain porousness,
The resistance that can thus make to loosen the soil suffered by colter main body greatly reduces.Further, the polytetrafluoro of entire colter surface coating
Ethylene super-hydrophobic coat is difficult to adhere to knife colter surface, efficiently reduces soil and weeds to colter table so that gluing wet soil
The adherency in face.In conclusion passing through the coupling of colter surface shape and character, the digging that colter is born in operation process
Digging resistance significantly reduces, and soil adhesion situation weakens significantly, and colter working efficiency is improved obviously, and service life is increased
Add, to achieve the purpose that initially to invent.
