Description
Technical field
The present invention relates to a kind of digging tool, more particularly to a kind of bionical excavator bucket teeth.
Background technology
Excavator, is to be excavated higher or lower than holding the material of machine side with scraper bowl, and load haulage vehicle also known as excavating machinery
Or unload to the earthmoving machinery of rickyard.Scraper bowl is excavator main energy-consuming parts in the course of the work.Bucket tooth is located at excavator
The end of scraper bowl, is its main soil-engaging component.During work, bucket tooth wedges soil at a certain angle, and destruction Soil Interface layer makes shovel
Bucket enters soil with less resistance.The performance of bucket tooth directly affects the excavation performance of power shovel or even excavator, reduces
Bucket tooth soil cutting resistance can effectively improve the digging efficiency of excavator.Bucket tooth can produce abrasion when in use, cause cutting energy
Power reduction.Abrasion is its main failure mode.The method of common several raising bucket tooth performances has improvement bucket tooth configuration, improves
Wearability, mining track of optimization bucket tooth of bucket tooth material etc..
The content of the invention
The purpose of the present invention is to solve the deficiency of above-mentioned technical problem, there is provided a kind of Bionic excavation bucket tooth, its resistance of burying
Power is greatly reduced, and wear-resistant ability is greatly enhanced, and improves operating efficiency.
The present invention by installation end and touch soil end constitute, touch soil end be located at installation end front portion, installation end be provided with upper surface,
Lower surface and cavity, there is inner side to touch soil face, the tactile soil face in outside and front end Chu Tu faces to touch soil end, and front end Chu Tu faces are a bent circular arc
Face, arc radius are 3-8mm, and soil face is touched in inner side and outside is touched soil face and is oppositely arranged, and the contour curve initiating terminal in soil face is touched in inner side
Tangent with front end Chu Tu faces circular arc upper end, the contour curve end that soil face is touched in inner side is tangent with the upper surface of installation end, and outside is touched
The contour curve initiating terminal in native face with enter that front end Chu Tu faces circular arc lower end is tangent, outside is touched the contour curve end in soil face and is installed
The lower surface at end is tangent, and described installation end has cross through hole；
The contour curve that soil face is touched in the inner side is by parametric equation y1=-9 × 10-4x3-0.0057x2+0.2347x+
3.006, it is to amplify 6 times of curved sections for drawing in 0-14mm in x spans；
The contour curve that soil face is touched in the outside is by parametric equation y2=-9 × 10-5x3-0.0057x2+0.2347x+
7.973, it is to amplify 6 times of curved sections for drawing in 0-14mm in x spans.
It is an advantage of the invention that：The bionical excavator bucket teeth, its appearance profile curve is derived from badger fore paw toe, and badger is a kind of
Be good at the troglobite of digging, forelimb pawl toe-end has strong and thick pawl long, and pawl approximate toe long is long, its claw it is elongated and
Bending, is the powerful of digging.The contour curve of fore paw toe can use least square fitting, and its shape meets drag reduction, resistance to
The bionics principle of mill.The experiment proved that the bionical bucket tooth can improve the operating efficiency of excavator, extend the life-span of bucket tooth with
And excavator energy consumption in the course of the work is reduced, reach energy-efficient purpose.

Specific embodiment
Refer to shown in Fig. 1, Fig. 2 and Fig. 3, the present embodiment is made up of installation end 1 and tactile soil end 2, touches soil end 2 and is located at and pacifies
Fill the front portion at end 1, installation end 1 is provided with upper surface 101, lower surface 102 and cavity 103, touch soil end 2 have inner side touch soil face 21,
Soil face 22 and front end Chu Tu faces 23 are touched in outside, and front end Chu Tu faces 23 are a circular arc camber, and arc radius are 3-8mm, and soil is touched in inner side
Face 21 and outside are touched soil face 22 and are oppositely arranged, and contour curve initiating terminal and the circular arc upper end of front end Chu Tu faces 23 in soil face 21 are touched in inner side
Tangent, the contour curve end that soil face 21 is touched in inner side is tangent with the upper surface 101 of installation end 1, and the profile that soil face 22 is touched in outside is bent
Line initiating terminal with enter that the circular arc lower end of front end Chu Tu faces 23 is tangent, outside is touched under the contour curve end in soil face 22 and installation end 1
