Description
Technical field
The invention belongs to agricultural machinery technological field, and in particular to a kind of wear-resisting potato digger plow of bionic, drag-reducing.
Background technology
It is to excavate potato wedges and under rib thrust by potato wedges and subsidiary mud that the main task of potato digger plow is
Soil is transported to separation grading plant and is for further processing.Excavation performance is one of evaluation potato harvester performance important
Index, and digger blade is the principal element that performance and potato picker overall performance are excavated in influence.China is vast in territory, potato
The soil texture in class producing region is different with plantation agronomic conditions, such as China's In Soils of Northeastern it is viscous weigh, many stones of the Northwest's soil with
And southern area soil chiltern, overseas equipment do not adapt to the complicated regional condition of China, it is difficult to large-scale popularization application at home.
Compared to external potato type harvesting machinery, domestic type can't completely adapt to the demand of production development, be primarily present three aspects
Problem：One is poor reliability.Potato type harvesting machinery soil environment is complicated, and single type digging mechanism is less efficient, it is impossible to reach
Use basic demand.Two is bad adaptability.The potato type harvesting machinery excavation portion under the conditions of different soil and different plants
Part can not effectively solve that excavating resistance is big, soil adhesion serious, sandstone abrasion shovel face the problems such as.Three is not enough power reserve.
Excavating depth increases and the big plot operation of soil specific resistance, it is difficult to meet the power needs that potato wedges is excavated and be separate.
Existing potato picker digger blade form is single, simple structure, and it is mostly grafter (triangle to excavate shovel face shape
Shovel, bar shaped shovel), concave surface shovel, flute profile shovel, these traditional potato digger plows are characterised by that the shape of its cross section is trapezoidal
Or it is near trapezoidal, this kind of shape of cross section cause digger blade when potato wedges is excavated because the real contact area of soil and shovel face is big and
Clay seriously causes excavation soil-entering resistance big, and then resistance is big when causing digger blade operation, high energy consumption, breaks ground, hack ability
Difference, potato-damaging rate is higher, under the conditions of complicated ground condition, there is bad adaptability, the low problem of reliability.Therefore, the present invention is wanted
The technical problem of solution is to design a kind of bionic, drag-reducing potato digger plow of wavy cross-section to solve current potato harvest
Machine excavating resistance is big, high energy consumption, hack ability of breaking ground, and takes off the technical problems such as soil effect difference, improves the whole machine of potato picker
Transaction capabilities and efficiency.
The content of the invention
It is an object of the invention to provide a kind of bionic, drag-reducing digger blade of potato picker wavy cross-section, can be effectively
Turn up soil and potato wedges, good with penetration performance, it is good to take off soil effect, breaks ground, strong hack ability and the features such as small excavating resistance,
The operating efficiency and potato picker overall performance for excavating potato wedges can be improved.To achieve these goals, the present invention is taken
Technical scheme be：
The present invention is made up of shovel face 1 and spade 2, it is characterised in that：The front end trigonum of burying of the shovel face 1 is provided with buries
The excavation surface edge of shovel 5；Spade 2 is provided with 2 counterbores 4, the lower end of spade 2 and the upper end rounding off of shovel face 1；The two ends of spade 2 are transition
Circular arc, in longitudinal central axis line 3, transition arc radius are in the center of circle of transition arc：90-120mm；Spade 2 is planar structure, shovel
The shape in face 1 is on the symmetrical distribution of longitudinal central axis line 3；Shovel face 1 has cross-sectional profiles curve A and Xray films bent

The bionical Inverse seeking design of line.Wherein bionical matrix arcuate structure is respectively provided with the geometry of specific curvature, by 3-D scanning,
The fit equation of digger blade matrix arcuate structure outboard wheel profile is obtained through least square method and two-dimensional Cartesian coordinate system again.This is imitated
Raw structure can imitate Oriental burmeister front foot digging mechanism, be conducive to digger blade fast power-saving to bury, so as to reduce soil-entering resistance.
The digger blade shovel face of wavy cross-section of the invention is the base blood clam bionical Inverse seeking design of cross-sectional outer contour line,
Wherein bionical shovel face has the geometry of specific curvature, by 3-D scanning, then through least square method and two-dimentional rectangular co-ordinate
System obtains the fit equation of shovel face cross-sectional profiles line.Imitate the housing profile of Chlamys farreri, Ke Yiti in the bionical section of waveform
The wearability of shovel face high.Due to the wavy cross-section structure of shovel face, the bionic geometric structure can not only change soil with shovel
The motion state in face, moreover it is possible to change the contact angle of soil and shovel face.The bulge-structure for for example going up shovel face is conducive to breaking ground and hack,
It is provided simultaneously with guiding the effect of soil block shunting, is conducive to the conveying of soil particle and separates, reduces the adhesion of soil and shovel face
With frictional force, so as to play drag-reduction effect.Meanwhile, lower tactile mamoty face advantageously reduces soil particle with lower tactile mamoty face surface
Real contact area, reach the adhesion and frictional resistance for reducing soil and lower tactile mamoty face, soil is shoveled along digger blade
The forms of motion in face is changed into by original sliding contact and is in rolling contact, and largely reduces friction resistance of the soil to shovel face
Power.Above-mentioned the reason for, will all reduce the adhesion and resistance that up and down touch mamoty face surface of the soil to whole digger blade matrix, make
Shovel face is integrally presented wearability advantage high.
Bionic arc digger blade matrix of the present invention is combined design with wavy cross-section shovel face, effectively fast power-saving can be buried
And turn up soil and potato wedges, solving existing digger blade and have that soil-entering resistance is big, shovel face clay phenomenon is serious, breaks ground, hack energy
Power is poor, the problems such as potato-damaging rate is higher, with penetration performance it is good, break ground, hack ability is strong, de- soil effect is good, wear-resisting and traction resistance
The characteristics of power is small, can improve potato digging efficiency and potato picker overall performance.
The beneficial effect of patent of the present invention is:One, the geometry present invention improves existing potato digger plow face,
It is bionical prototype by the geometry of the contour line of blood clam cross-sectional outer, devises the bionical digger blade of wavy cross-section, so
Structure be conducive to the digger blade can smoothly to be broken ground in digging, hack, reach wear-resisting effect, and be conducive to guiding to shunt
Shovel face soil to transfer separation device below, so as to improve de- soil nature energy.The cross section of whole shovel face is waveform, this
The structure of sample can reduce the contact area of soil and tactile mamoty face, and the soil stress point when can improve digger blade digging
Cloth, the soil shape that change is mined reduces soil adhesion and friction, so as to reduce excavating resistance, wearability is improved, through experiment
Checking, more than 15% is improved than traditional existing potato digger plow drag-reducing abrasion-resisting.
Secondly, that the design of digger blade matrix of the invention longitudinal direction arcuate structure is based on Oriental burmeister front foot pawl toe outline is bent
The bionical reverse of line and obtain, using the digging performance that Oriental burmeister front foot pawl toe is excellent, improve digger blade penetration performance.
