Abstract
The invention discloses a bionic spade head which comprises an interior surface, an external surface and a spade head tip, wherein the interior surface is in inner concave shape; the interior surface is formed in the way that a first curve sweeps along a second curve; the trend of ridge wires in the middle of the interior surface and the external surface satisfies the second curve; the morphology of the spade head tip satisfies a third curve; the projection of two end points of the first curve and three end points of the third curve are connected to form a contour curve of the spade; the first curve meets the formula: y=-0.0007x<2>+0.1518x+55.294, wherein 5<x<215; the second curve meets the formula: y=12.812e<0.0667x>, wherein 10<x<45; and the third curve meets the formula: y=-2*10<-6>x<4>+0.0003x<3>+0.0234x<2>-1.7435x+54.859, wherein -35<x<95. Compared with traditional spades, the bionic spade head has the advantages that the feed resistance is lowered by 86%, and the wear resistance is substantially improved.
Description
Technical field
The present invention relates to a kind of bionical shovel head.
Background technology
Spade, a kind of farm implements, for ploughing, shoveling soil etc.But in use, there is the problems such as large, easy to wear, the easy clay of excavating resistance, service life is short in shovel head.At present, mostly people are to spray paint by smearing shovel head, Surface hardened layer etc. improves above-mentioned situation.But these methods all can not fundamentally well address these problems.
Summary of the invention
Order of the present invention is to provide a kind of bionical shovel head, and the present invention starts with from the exterior appearance of spade, relates to the design at spade inner surface tendency, outer surface pattern, shovel head tip etc., solves the problems such as large, the easy wearing and tearing of excavating resistance of spade.
Ostrich has sane, lasting high speed ability to run, lasting running speed about 50 ~ 60 kilometers/hour, and sustainable about 30 minutes.Ostrich toes first touches one of husky position as main, play fix the sand, current limliting and increase thrust.As can be seen from the structure of ostrich toes first, ostrich toes first has four obvious architectural features, comprises toe point plane domain, inner groovy region, back inverted triangle structure and side recess region.Forward plane region is similar to a triangle, and when touching husky, triangle projective planum region has compaction to sandy soil; Enter in husky process, triangular tip reduces into husky resistance, is easy to into sand; After entering sand, the active force of sandy soil can form making a concerted effort forward on this plane, is conducive to increasing traction.Inner groovy region tactile husky time can make that sandy soil are fastening is gathered in this, produce interim " induration ", fix the sand, current limliting and anti-skidding effect.Back inverted triangle body structure surface is smooth, and has special arc structure, can make toes first level and smooth enter sandy soil, reduce the disturbance to sandy soil, reduce soil-entering resistance.In addition, ostrich tarsometatarsus bone and the IIIth dorsal surface of toes individual layer is superimposed arranges scale, scale surface longitudinal texture is obvious, is easy to improve the resistance to husky polishing machine of scale; Toe back of the body scale makes the IIIth toe penetrated in sand ground play anti-slip positioning by toenail.
The present invention has that inner surface, outer surface and shovel head are most advanced and sophisticated, and inner surface becomes inner concave shape, and inner surface to be scanned along the second curve by the first curve to form, satisfied second curve of middle crestal line tendency of inner surface and outer surface; The most advanced and sophisticated pattern of shovel head meets the 3rd curve; Three end points of the first curve two-end-point and the 3rd curve project and are connected to form the contour curve of spade; Curvilinear equation meets respectively:
First curve: y=-0.0007x
2+ 0.1518x+55.294, wherein: 5<x<215;
Second curve: y=12.812e
0.0667x, wherein: 10<x<45;
3rd curve: y=-2 × 10
-6x
4+ 0.0003x
3+ 0.0234x
2-1.7435x+54.859; Wherein :-35<x<95;
From middle crestal line to both sides outline line, the linear reduction of shovel head thickness.
The crestal line both sides of outer surface are uniformly distributed width, the degree of depth, groove that length is equal.
The outer surface width ratio that width and the side of each groove are close to is 1:3.
The effect that the present invention is useful is:
1, shovel head tip is beneficial to set, anti-slip positioning, improves spade penetration performance; Inner surface is solid soil easily, improves the bag soil nature energy of spade; Outer surface pattern is beneficial to the excavating resistance reducing spade, and equally distributed groove is conducive to the anti-wear performance improving spade, reduces the degree of wear.
2, the present invention is compared with traditional spade: soil-entering resistance reduces by 86%, and anti-wear performance significantly improves.
