Abstract
The utility model discloses a bionic excavating bucket tooth which comprises an installation end; and the installation end is provided with an upper slope, a lower slope and a concave cavity. The bionic excavating bucket tooth is also provided with an inner-side soil contacting surface, an outer-side soil contacting surface and a soil-digging front end surface, wherein the soil-digging front end surface is a circular-arc curved surface; the radius of the circular arc is 4-10mm; the inner-side soil contacting surface and the outer-side soil contacting surface are arranged in a face-to-face way; the starting end of the outline curved surface of the inner-side soil contacting surface is tangent with the upper end of a projection circular arc of the soil-digging front end surface; the tail end of the outline curved surface is tangent with the upper slope of the installation end; the starting end of the outline curved surface of the outer-side soil contacting surface is tangent with the lower end of the projection circular arc of the soil-digging front end surface; and the tail end of the outline curved surface of the outer-side soil contacting surface is tangent with the lower slope of the installation end. Experiments prove that the abrasion resistance capability and the abrasion resistance strength of the bionic bucket tooth are superior to the bucket tooth at the present market. The abrasion resistance capability and the abrasion resistance strength of the bionic bucket tooth are greatly improved, the working efficiency is improved, and a purpose of saving energy is realized.
Description
Technical field
The utility model relates to the tooth that a kind of excavator is used, and especially relates to a kind of bionical excavation bucket tooth.
Background technology
Excavator is a kind of engineering machinery of extensive use, and it touches native parts mainly is bucket, at the front end of bucket the excavation bucket tooth is installed all.Excavating bucket tooth has the function of breaking ground, and helps scraper bowl and buries, and therefore excavating bucket tooth is one of consumable accessory on the excavator.Under normal conditions, the failure mode of excavation bucket tooth is wearing and tearing or fracture.The general structure of existing excavation bucket tooth is very simple, in order to cast and easy to process, employing be simple curve modeling, the flank of tooth is that several sections circular arc cambers constitute.The structure of conventional bucket tooth receives an outside tangential force when causing bucket tooth to bury, and bucket tooth has bandy trend, and strength failure takes place easily; In long-term operation process, the degree inequality that bucket tooth front end both sides are frayed, interior lateral wearing is big, and outer lateral wearing is little, and bucket tooth can be more prone to take place strength failure.
The utility model content
The purpose of the utility model is to be the deficiency that solves the problems of the technologies described above, and a kind of bionical excavation bucket tooth is provided, and its wear-resistant ability and intensity strengthen greatly, have improved operating efficiency.
The utility model is the deficiency that solves the problems of the technologies described above, and the technical scheme that is adopted is: a kind of bionical excavation bucket tooth comprises installation end; Installation end is provided with top incline and bottom incline and cavity, also is provided with the inboard and touches that native face, the outside touch native face, the front end face that buries, and the front end face that buries is a circular arc camber; Arc radius is 4-10mm; The inboard is touched native face and the outside and is touched native face and be oppositely arranged, and it is tangent with the front end face projection circular arc upper end of burying that the contour curve initiating terminal of native face is touched in the inboard, and terminal top incline with installation end is tangent; It is tangent with the front end face projection circular arc lower end of burying that native facial contour curve initiating terminal is touched in the outside, and terminal bottom incline with installation end is tangent;
The contour curve that native face is touched in described inboard be by parametric equation
in the x span is 1580-4160 μ m and amplify 20 times of curved sections that draw;
The contour curve that native face is touched in the described outside be by parametric equation
in the x span is 1580-4160 μ m and amplify 20 times of curved sections that draw.
The beneficial effect of the utility model is: this bionical excavation bucket tooth; Its appearance profile parameter of curve derives from the east mole cricket and excavates the second toe; The east mole cricket is a kind of soil fauna of being good at excavating; It excavates pawl toe is hollow structure, and its contour curve can be used the Gauss equation match, its shape meets bionics principle high-strength, drag reduction.The bionical bucket tooth of development is in the process of burying, and flank of tooth both sides are stressed evenly, and the gear tooth friction resistance is less; In the process of wearing and tearing, the uniform wear of flank of tooth both sides, its contour shape is almost constant.Antiwear property and intensity through experiment showed, this bionical bucket tooth all are superior to present bucket tooth on the market.Its wear-resistant ability and intensity strengthen greatly, have improved operating efficiency, have also realized purpose of energy saving.

The specific embodiment
As shown in the figure, a kind of bionical excavation bucket tooth comprises installation end 1; Installation end 1 is provided with top incline 101, bottom incline 102 and cavity 103, and the cavity of installation end is connected with scraper bowl through fixing pin, cooperates more convenient; Also be provided with the inboard and touch that native face 2, the outside touch native face 3, front end face 4 buries; The front end face 4 that buries is a circular arc camber, and arc radius is 4-10mm, and the inboard is touched native face 2 and touched native face 3 with the outside and be oppositely arranged; The contour curve initiating terminal that native face 2 is touched in the inboard is tangent with the front end face 4 projection circular arcs upper end of burying and be connected; Terminal top incline 101 with installation end is tangent, that is to say and constitutes smooth joint face in the junction, and it is tangent with the front end face 4 projection circular arc lower ends of burying and be connected that native face 3 contour curve initiating terminals are touched in the outside; Terminal bottom incline 102 with installation end is tangent; And constitute smooth joint face in the junction, and the installation end in the utility model is identical with conventional bucket tooth front end, and the angle of its top incline and bottom incline is touched the contour curve that native face and the outside touches native face according to the inboard and is limited and curve assurance junction slyness;
The contour curve that native face 2 is touched in described inboard be by parametric equation
in the x span is 1580-4160 μ m and amplify 20 times of curved sections that draw;
The contour curve that native face 3 is touched in the described outside be by parametric equation
in the x span is 1580-4160 μ m and amplify 20 times of curved sections that draw.
This bionical excavation bucket tooth; Its appearance profile parameter of curve derives from the east mole cricket and excavates the second toe, and the east mole cricket is a kind of soil fauna of being good at excavating, and it excavates the pawl toe is hollow structure; Its contour curve can be used the Gauss equation match, its shape meets bionics principle high-strength, drag reduction.The bionical bucket tooth of development is in the process of burying, and flank of tooth both sides are stressed evenly, and the gear tooth friction resistance is less; In the process of wearing and tearing, the uniform wear of flank of tooth both sides, its contour shape is almost constant.Prove through experiment: its wear-resistant ability and intensity strengthen greatly, have improved operating efficiency, have also realized purpose of energy saving.
