Abstract
A kind of runner boot belongs to agricultural machinery category, relate to the machinery of trench digging when a kind of agricultural fertilizer, sowing, which solves the acute angle plough amount of breaking ground that current agricultural machinery generally adopts large, dry wet soil easily mixes, be unfavorable for the realistic problem that preserves soil moisture, also overcomes disk coulter compared with shortcoming hard stratum needing enough vertical loads and just can bury simultaneously.Its technical scheme is: a kind of runner boot is primarily of applicator boot seam (1), fulcrum bar of the spring seam (2), straight pin seam (3), fixed handle seam (4), spring pressure pad (5), Compress Spring (6), bearing pin (7), spring catch (8) composition.Compress Spring (6) plays safeguard protection effect, is damaged when preventing plough from running into the hard object such as stone.A kind of runner boot amount of breaking ground is little, and dry wet soil not easily mixes, and it is good to enter soil nature, and required vertical load of burying is little, can be applicable on light-duty no-tillage seeding machine, is with a wide range of applications.
Description
Technical field
A kind of runner boot belongs to agricultural machinery.
Background technology
Plough is the key operation parts of sower, fertilizer distributor, can be divided into acute angle plough and obtuse angle plough by penetrating angle difference.The former comprises shovel formula, core share type and boots shoe etc., and the latter is representative is disc type.Although it is good that acute angle plough enters soil nature, the amount of breaking ground is large, and dry wet soil easily mixes; be unfavorable for soil moisture conservation, greatly developing in recent years along with conservation tillage, the especially in the ranks continuous application of seeding technique; in northern Dryland, acute angle plough has gradually by trend that obtuse angle plough replaces.Wherein for disk coulter, it is more that people pay close attention to, and practical application is also comparatively extensive, but the architecture quality relation of its operation effectiveness and facility is very large, compared with hard stratum needing enough vertical loads, this makes its application on light-duty no-tillage seeding facility be very limited.
Summary of the invention
The object of the present invention is to provide a kind of runner boot, this plough belongs to obtuse angle plough, and the amount of breaking ground is little, dry wet soil not easily mixes, and is beneficial to soil moisture conservation, and compared with disk coulter, it is good that this plough enters soil nature, and required vertical load of burying is little, can be applicable on light-duty no-tillage seeding machine.
Above-mentioned purpose of the present invention realizes like this.Accompanying drawings is as follows:
A kind of runner boot is primarily of applicator boot seam (1), fulcrum bar of the spring seam (2), straight pin seam (3), fixed handle seam (4), spring pressure pad (5), Compress Spring (6), bearing pin (7), spring catch (8) composition.It is characterized in that said applicator boot seam (1) is hingedly fixed in fixed handle seam (4) by straight pin seam (3), split pin, by the fulcrum bar of the spring installing hole of fulcrum bar of the spring seam (2) through fixed handle seam (4), fulcrum bar of the spring seam (2) is hingedly fixed in applicator boot seam (1) by bearing pin (7), spring catch (8), fulcrum bar of the spring seam (2) and fixed handle seam (4) is linked together by spring pressure pad (5), Compress Spring (6), nut.Sliding cutter (11) is the part in applicator boot seam (1), also be a kind of workpiece of runner boot, the effect of sliding cutter to soil is sliding cutting, and the structural factor affecting this Sliding cutting action mainly contains blade curve, slip cutting angle θ and sliding cutter thickness δ.Sliding cutting is more laborsaving than impact cutting, and Cutting Drag reduces along with the increase of slip cutting angle, increases along with the increase of angle of friction.Obviously, for sliding cutter, cutting edge is that curve is more laborsaving than straight line.In design, select exponential function curve, and set up coordinate system as shown in Figure 1.Make L
aC=b, A point coordinates is (X
a, Y
a), then B, C two point coordinates be respectively B (X
a+ BC, Y
a+ b), C (X
a, Y
a+ b).Cross the tangent line that A, B make blade curve AB respectively at 2, if the plough direction of motion is along X-axis forward, then θ in figure
a, θ
bfor the slip cutting angle of A, B 2.B point is the peak of blade curve, θ
bfor initial slip cutting angle.The equation of curve A B is y=a
x(a > 1) differentiates
y′＝ylna (1)
The derivative at A, B 2 place is respectively

A′＝y
Alna＝tanα
A＝tan(π/2-θ

B′＝y
Blna＝tanα
B＝tan(π/2-θ

Simultaneous formula (2) ~ (4) arrange and can obtain
So the equation that can obtain curve A B is
For making plough have good versatility, can be used for sowing and can be used for again fertilising, in equation, parameter b should determine according to maximum fertilization depth.For corn, its maximum fertilization depth is generally about 100mm, and ditching depth suitably should be greater than fertilization depth, therefore gets parameter b=150mm.If initial slip cutting angle θ
btoo small, then the action of sliding cutting can not complete smoothly, and sliding cutter increases the disturbance of soil, and soil easily upwards stirs, and causes dry wet soil to mix, only has and work as θ
bsliding cutting action could be produced during > φ.Actually record angle of friction φ=23 ° on field trial ground, therefore get θ
b=23 °.Clearly, from B point, on blade curve AB, the slip cutting angle of each point increases gradually, and the structure principal element of the tractive resistance and soil-entering resistance that affect runner boot is slip cutting angle θ
a, sliding cutter thickness δ is secondary cause.As initial slip cutting angle θ
bsliding cutting action could be produced during > φ.At θ
bwhen identical, slip cutting angle θ
atime within the scope of 35 ° ~ 55 °, plough tillage resistance and soil-entering resistance less, the integrated performance index of sliding cutter is more satisfactory, especially better in comparatively hard stratum effect of burying, and can be used as the applicator boot of light-duty no-tillage seeding machine and rowmiddle seeder.
In the overall structure of runner boot except sliding cutter, also to there be plough handle and defeated fertilizer (kind) device.For reducing the adverse effect of these two parts to plough transaction capabilities as far as possible; the bottom cutting edge angle of plough handle gets 45 °, and clearance angle of burying should meet γ > φ, actually gets γ=30 °; Compress Spring plays safeguard protection effect, damages sliding cutter when preventing from running into the hard object such as stone.
Beneficial effect
The utility model patent provides a kind of runner boot, this apparatus structure is novel, simply compact, adjustment operation is simple and easy, quick and easy, solve the acute angle plough amount of breaking ground that current agricultural machinery generally adopts large, dry wet soil easily mixes, be unfavorable for the realistic problem of soil moisture conservation, also overcome disk coulter compared with hard stratum needing enough vertical loads, the shortcoming just can buried.This runner boot belongs to obtuse angle plough, and the amount of breaking ground is little, and dry wet soil not easily mixes, be beneficial to soil moisture conservation, and compared with disk coulter, it is good that this plough enters soil nature, required vertical load of burying is little, can be applicable on light-duty no-tillage seeding machine, is with a wide range of applications.
