The invention discloses a kind of bionical shovel head, has inner surface, outer surface and shovel head tip, and for inner surface into inner concave shape, inner surface is to be scanned to form along the second curve by the first curve, and the middle crestal line tendency of inner surface and outer surface meets the second curve；Shovel head tip pattern meets the 3rd curve；Three end points of the first curve two-end-point and the 3rd curve project the contour curve for being connected to form spade；First curve：Y=0.0007x2+ 0.1518x+55.294, wherein：5<x<215；Second curve：Y=12.812e0.0667x, wherein：10<x<45；3rd curve：Y=2 × 10‑6x4+0.0003x3+0.0234x2‑1.7435x+54.859；Wherein：‑35<x<95；It is of the invention compared with traditional spade：Soil-entering resistance reduces by 86%, and anti-wear performance significantly improves.
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..However, in use, shovel head exist excavating resistance it is big,
Easy to wear, easy clay, the problems such as service life is short.At present, people be mostly by shovel head is smeared spray painting, Surface hardened layer etc. come
Improve the above situation.But these methods all can not fundamentally solve these problems well.
The content of the invention
The mesh 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, is related in spade
The design at surface tendency, outer surface pattern, shovel head tip etc., to solve the problems such as excavating resistance of spade is big, easily wears.
Sane, lasting high speed ability to run that ostrich has, continue about 50~60 kilometers/hour of running speed, and can hold
Renew a contract 30 minutes.Ostrich toes first as one of husky position is mainly touched, play fix the sand, current limliting and increase thrust.From ostrich
The structure of toes first, which can be seen that ostrich toes first, four obvious architectural features, including toe point plane domain, inner groovy area
Domain, back inverted triangle structure and side recess region.Forward plane region is similar to a triangle, and when touching husky, triangle is put down
Face region has compaction to sandy soil；During entering sand, triangular tip is reduced into husky resistance, is easy into sand；It is husky after entering sand
Soil active force can be formed on this plane forward make a concerted effort, be advantageous to increasing traction.Inner groovy region is in tactile Sha Shike
So that sandy soil fastening is gathered in this, interim " induration " is produced, is fixed the sand, current limliting and anti-skidding effect.Back inverted triangle structure table
Face is smooth, and has special arc structure, can make the entrance sandy soil that toes first is smooth, reduce the disturbance to sandy soil, reduce
Soil-entering resistance.In addition, ostrich tarsometatarsus bone and the IIIth dorsal surface of toes individual layer overlapping arrange scale, scale surface longitudinal texture is bright
It is aobvious, it is easy to improve the resistance to husky polishing machine of scale；The IIIth toe that toe back of the body scale makes to penetrate in sand ground plays anti-slip positioning by toenail
Effect.
The present invention has inner surface, outer surface and shovel head tip, and for inner surface into inner concave shape, inner surface is by the first curve edge
The second curve and scan and form, the middle crestal line of inner surface and outer surface meets the second curve；Shovel head pointed edge contour line is expired
The 3rd curve of foot；Three end points of the two-end-point of the first curve and the 3rd curve are attached, form spade contour curve；It is bent
Line equation meets respectively：
First curve：Y=-0.0007x2+ 0.1518x+55.294, wherein：5<x<215；
Second curve：Y=12.812e0.0667x, wherein：10<x<45；
3rd curve：Y=-2 × 10-6x4+0.0003x3+0.0234x2-1.7435x+54.859；Wherein：-35<x<95；
From middle crestal line to both sides contour line, the linear reduction of shovel head thickness.
The middle crestal line both sides of outer surface are uniformly distributed width, depth, the groove of equal length.
The width of each groove and side close to outer surface width ratio be 1:3.
The invention has the advantages that：
1st, shovel head tip is beneficial to set, anti-slip positioning, improves spade penetration performance；The easily solid soil of inner surface, improves spade
Bag soil nature energy；Outer surface pattern is beneficial to the excavating resistance for reducing spade, and equally distributed groove is advantageous to improve spade
Anti-wear performance, reduce the degree of wear.
2nd, it is of the invention compared with traditional spade：Soil-entering resistance reduces by 86%, and anti-wear performance significantly improves.

Embodiment
Refer to shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the present embodiment has inner surface 1, outer surface 4 and shovel head tip
2, inner surface 1 is into inner concave shape, and inner surface 1 is to be scanned to form along the second curve 7 by the first curve 3, inner surface 1 and outer surface 4
Middle crestal line meet the second curve 7；2 edge wheel profiles of shovel head tip meet the 3rd curve 5；By the two-end-point of the first curve 3
It is attached with three end points of the 3rd curve 5, forms spade contour curve；Curvilinear equation meets respectively：
First curve 3：Y=-0.0007x2+ 0.1518x+55.294, wherein：5<x<215；
