Abstract
The utility model discloses a kind of bionical excavator bucket teeth, be made up of installation end and tactile soil end, touch the front portion that soil end is positioned at installation end, installation end is provided with upper surface, lower surface and cavity, touch soil end and there is tactile native face, inner side, native face is touched in outside and native face is touched in front end, it is a circular arc camber that native face is touched in front end, arc radius is 3-8mm, tactile native face, inner side and outside are touched native face and are oppositely arranged, it is tangent that circular arc upper end, native face is touched in the contour curve initiating terminal in tactile native face, inner side and front end, the upper surface that the contour curve end in native face and installation end are touched in inner side is tangent, to touch circular arc lower end, native face tangent with entering front end for the outside contour curve initiating terminal that touches native face, the lower surface that the contour curve end in native face and installation end are touched in outside is tangent, the experiment proved that, this bionical bucket tooth effectively reduces the soil-entering resistance of tooth, alleviates the wearing and tearing of bucket tooth tip, increases the service life, and also achieves energy-conservation object.
Description
Technical field
The utility model relates to a kind of excavating tools, particularly relates to a kind of bionical excavator bucket teeth.
Background technology
Excavator, also known as excavation machinery, is excavate higher or lower than the material holding machine side with scraper bowl, and loads haulage vehicle or unload the earth moving plant to rickyard.Scraper bowl is excavator main energy-consuming parts in the course of the work.Bucket tooth is positioned at the end of power shovel, is its main soil-engaging component.During work, bucket tooth wedges soil at a certain angle, spoiled soil boundary layer, makes scraper bowl enter soil with less resistance.The performance of bucket tooth directly affects the excavation performance of power shovel and even excavator, reduces the digging efficiency that bucket tooth soil cutting resistance effectively can improve excavator.Bucket tooth can produce wearing and tearing in use, causes cutting power to reduce.Wearing and tearing are its main failure modes.The method of common several raising bucket tooth performances has improves bucket tooth configuration, the abrasion resistance of raising bucket tooth material, the mining track etc. of optimization bucket tooth.
Summary of the invention
The purpose of this utility model is the deficiency for solving the problems of the technologies described above, and provides a kind of Bionic excavation bucket tooth, and its soil-entering resistance reduces greatly, and wear-resistant ability strengthens greatly, improves operating efficiency.
The utility model is made up of installation end and tactile soil end, touch the front portion that soil end is positioned at installation end, installation end is provided with upper surface, lower surface and cavity, touch soil end and there is tactile native face, inner side, native face is touched in outside and native face is touched in front end, it is a circular arc camber that native face is touched in front end, arc radius is 3-8mm, tactile native face, inner side and outside are touched native face and are oppositely arranged, it is tangent that circular arc upper end, native face is touched in the contour curve initiating terminal in tactile native face, inner side and front end, the upper surface that the contour curve end in native face and installation end are touched in inner side is tangent, to touch circular arc lower end, native face tangent with entering front end for the outside contour curve initiating terminal that touches native face, the lower surface that the contour curve end in native face and installation end are touched in outside is tangent,
The contour curve that native face is touched in described inner side is by parametric equation y
1=-9 × 10
-4x
3-0.0057x
2+ 0.2347x+3.006 is amplify 6 times of curved sections drawn in 0-14mm in x span;
The contour curve that native face is touched in described outside is by parametric equation y
2=-9 × 10
-5x
3-0.0057x
2+ 0.2347x+7.973 is amplify 6 times of curved sections drawn in 0-14mm in x span.
The utility model has the advantages that: this bionical excavator bucket teeth, its appearance profile curve stems from badger fore paw toe, and badger is a kind of troglobite of being good at digging, forelimb pawl toe-end all has strong and thick long pawl, the long approximate toe of pawl is long, and its claw 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, wear-resisting bionics principle.The experiment proved that this bionical bucket tooth can improve the operating efficiency of excavator, extend the life-span of bucket tooth and reduce excavator energy consumption in the course of the work, reaching energy-efficient object.
