Description
Art
The invention belongs to agricultural machinery technological field, and in particular to a kind of matched curve type deep soil loosing shovel.
Background technology
Subsoiling is one of core technology of conservation tillage, and soil can break hard plough sole by subsoiling, improve
Efficiency of water application, reduce soil erosion, enhancing water and soil conservation ability, improve crop root growth environment, being advantageous to crop root
Grow, therefore the yield of root system crop can be increased considerably.Deep soil loosing shovel be subsoiling machinery critical component, existing depth
The problems such as tillage resistance is excessive, and topsoil disturbance quantity of being ploughed after subsoiling is excessive often be present when carrying out Subsoiler in pine shovel.
Therefore by the rational design and optimization to deep soil loosing shovel structure, to reduce tillage resistance and topsoil disturbance quantity, for machinery
Energy-saving consumption-reducing and retaining and conserveing soil moisture for soil have important meaning.
The content of the invention
The purpose of the present invention is by simulation analysis and optimization design, designs a kind of matched curve type deep soil loosing shovel, is solved deep
Deep soil loosing shovel tillage resistance and the problem of excessive topsoil disturbance quantity in loose operation process.
To solve above-mentioned technical problem, the present invention can be realized by following scheme：A kind of matched curve moldeed depth
Loose spade, including spade and the linkage section of frame (L), spade active section (II), spade and spear linkage section (R).Its feature exists
It is made respectively by following three sections of fit curve equations in spade blade curve OP, PQ, QR section：
Y=-0.3845x4-700.4x3-4.785×1010x2-1.453×108x-1.654×1010；
Y=8.951 × 10-5x5-0.02656x4+3.148x3-186.2x2+5496x-6.52×104；
Y=1.702 × 10-7x7+1.718×10-5x6+7.024×10-5x5+0.01474x4
+0.1653x3+0.944x2+2.342x-442.6
The matched curve QR main functions be undertake plough sole upturned soil on turn over, curve PQ main function is upturned soil
Broken, curve OP effect is that upturned soil is crushed to and reduced topsoil disturbance again.To keep uniform force, spade active section
Interior directrix (FG) and spade active section outer directrix (MN) it is consistent with blade curve, OR, MN are highly H0；To reduce farming
Resistance, cutting edge cutting edge angle (α) is selected 40 °, and penetrating angle (W) is selected 21 °；To increase cutting edge strength, tooth shape line BC, CD are used
Spirogyrate curve.
The beneficial effect of the invention is：To design deep soil loosing shovel spade shape, choose influence of the spear to soil and carry out
Discrete element simulation analysis, spade are designed as after spear effect the matched curve of necromancer earth particle trajectories thereon, shoveled by deep soil loosing shovel
The track of shank shape adapted soil reduces the impact momentum of soil and deep soil loosing shovel spade, and cutting edge cutting edge angle and penetrating angle
It is selected.Tillage resistance and topsoil disturbance quantity can be effectively reduced, reaches the effect that energy-saving mechanical subtracts consumption and soil is retained and conserved soil moisture.
Brief description of the drawings
Fig. 1 is the schematic diagram of structure of the present invention.
Fig. 2 is Fig. 1 of the present invention left view.
Embodiment
The invention is further illustrated with reference to the accompanying drawings and examples.A kind of matched curve type deep soil loosing shovel, by shoveling
Handle and the linkage section of frame (L), spade active section (II), spade and spear linkage section (R) three parts form.Wherein spade and machine
The linkage section (L) of frame has 6 a diameter of 12mm pit (I)；Spade active section (OR, MN) and spade and the linkage section of frame
(L) connected using arc transition, blade (OR, FG) Quenching Treatment, the matched curve QR main functions are to undertake plough sole soil
Turned on turning up soil, curve PQ main function is the broken of upturned soil, and curve OP effect is that upturned soil is crushed to and reduced top layer again
Soil disturbance；Spade is connected with spear linkage section (R) with spade active section (OR, FG) tangent-line transition, the folder between horizontal plane
Angle is 21 °.
By the research to subsoiling principle, and the application of traditional deep soil loosing shovel, to tillage resistance during subsoiling and top layer
The summary for the problems such as soil disturbance amount is larger.Moved, obtained in soil using discrete meta software (EDEM) simulation deep soil loosing shovel spear
The matched curve of soil particle movement locus and fit equation above spear are obtained, using line element design method to wiresizing optimization, is obtained
Spade active section (OR) curve.Devise tooth shape line (BC, CD), cutting edge angle (α), penetrating angle (W) simultaneously.A large amount of soil boxs pair
Show that matched curve type deep soil loosing shovel effectively reduces soil disturbance amount and tillage resistance, simultaneously than experiment and field comparison test
Plough sole can be broken, reduce the soil weight of plough sole, meet the requirement of Subsoiler.
The matched curve type deep soil loosing shovel material of the present invention is 65Mn steel, is worked by spade and the linkage section of frame (H), spade
Section (II), spade and spear linkage section (R) three parts form.Spade and the linkage section of frame (H) are cuboid, and width is
60mm, length 310mm, thickness 25mm, tilling depth scope are 200mm -300mm, and normal embedded depth (H) is 300mm.Shovel
Handle and the linkage section of frame (H) have 6 a diameter of 12mm pit (I), are fixed for bolt.At blade (OR, FG) quenching
Reason, spade blade curve OP, PQ, QR section are made by following three sections of fit curve equations respectively：
Y=-0.3845x4-700.4x3-4.785×1010x2-1.453×108x-1.654×1010；
Y=8.951 × 10-5x5-0.02656x4+3.148x3-186.2x2+5496x-6.52×104；
Y=1.702 × 10-7x7+1.718×10-5x6+7.024×10-5x5+0.01474x4
+0.1653x3+0.944x2+2.342x-442.6
The matched curve QR main functions be undertake plough sole upturned soil on turn over, curve PQ main function is upturned soil
Broken, curve OP effect is that upturned soil is crushed to and reduced topsoil disturbance again.To keep uniform force, spade active section
Interior directrix (FG) and spade active section outer directrix (MN) it is consistent with blade curve, OR, MN height H0For 280mm；To reduce
Tillage resistance, cutting edge cutting edge angle (α) is selected 40 °, and penetrating angle (W) is selected 21 °；To increase cutting edge strength, tooth shape line BC, CD are adopted
With spirogyrate curve.
In use, the pit (I) of spade and the linkage section of frame (H) and subsoiling frame bolt are fixed.Pass through soil box pair
Show that matched curve type deep soil loosing shovel effectively reduces soil disturbance amount and tillage resistance, than traditional broken-line type deep soil loosing shovel than experiment
Soil disturbance amount reduces 53.60%, and tillage resistance reduces 36.23%；Subtract than traditional circular arc type deep soil loosing shovel soil disturbance amount
Lack 66.18%, tillage resistance reduces 29.18%.Shown by field comparison test, matched curve type deep soil loosing shovel is than tradition
Broken-line type deep soil loosing shovel returns native area and adds 81.03%, and the native area that returns than traditional circular arc type deep soil loosing shovel adds 146.95%.
Therefore, soil box and field test demonstrate that matched curve type deep soil loosing shovel soil disturbance amount is smaller, and tillage resistance is smaller, meet protection
The requirement of property farming.
