Description
Technical field
It is a kind of for mounted on excavator and dredger the present invention relates to a kind of excavator and dredging scheme tooth
On bucket, it is used for the mechanical bucket tooth such as mining clay, belongs to excavator and dredging scheme field of engineering technology.
Background technology
Many different areas of activity in earth work especially carry out channel excavation, dredging, Coastal beach fill etc.
Different areas of activity is required to use excavator；Operation mainly is carried out using overlength arm bucket or scraper bowl on this excavator, because
The performance quality of this bucket or scraper bowl directly affects excavation and the performance of dredging scheme production capacity, the consumption of power, work
The service life of stationarity and other related components.
The bucket tooth being installed on bucket or scraper bowl is mainly integrally formed by bucket tooth body and carbide bit.Due to bucket tooth
Head carbide bit be in direct contact the earthwork, thus need certain wear-resisting property, but existing Tooth structure is not
Quite reasonable, not enough, therefore, the short life of actual use needs to be replaced frequently the intensity of bucket tooth, influences earth work operation,
Efficiency is reduced, to can also increase use cost.
Invention content
It is an object of the invention to overcome the shortcomings of the prior art, and offer is a kind of simple and reasonable for structure, uses peace
Dress is convenient, can increase the wearability of product surface, and intensity is big, fastness is high, improves the excavation of product service life and service efficiency
Machine and dredging scheme tooth.
The purpose of the present invention is by following technical solution to complete, and a kind of excavator and dredging scheme tooth, it is
The operation block on oblique top is carried by the prism-shaped intermediate of mounting seat, mounting seat top with location hole and top
Shape body integrally forms, and the intermediate on the mounting seat and top is integrally formed a square cone table, in top intermediate
Back side be integrally connected to the fillet blocks of lateral triangle, perpendicular arrangement, top and the intermediate
Upper end inclined-plane be in same plane, and constitute the prism-shaped intermediate；It is same flat on the top of the prism-shaped intermediate
The work blocks with oblique top is integrally connected on end face；The work blocks top end face is in tip cone end
Face, and the both sides inclined-plane of pointed cone end face is provided with more hard alloy blocks；Separately at the both ends of the work blocks top end face
Side and the outer surface of prism-shaped intermediate, which are welded, is connected with graininess hard alloy layer.
As preferred：The bottom surface of the mounting seat is provided with one and is in unidirectional concave lacking groove with oblique top,
The mounting hole set in being provided among the bottom surface of mounting seat, the one side of the mounting seat be provided perpendicular to concave lacking groove,
And the located lateral hole being connected to mounting hole；The top intermediate is provided with respect to the leading flank of back side more than 90 degree
Preceding bending edges and the oblique top for being transitioned into work blocks, equally the back side of the top intermediate also have one with before
The parallel rear bending edges of bending edges and the oblique top for being transitioned into work blocks；The fillet blocks of the triangle, top
The point of interface on the upper end inclined-plane of transverse plane and intermediate is in the centre of work blocks top end face.
The invention belongs to a kind of improvement to the prior art, have it is simple and reasonable for structure, it is easy to use, product can be increased
The wearability on surface, intensity is big, fastness is high, the features such as capable of improving product service life and service efficiency.

Fig. 2 is the overlooking structure diagram of the present invention.
Fig. 3 is the present invention looks up structural representation of the present invention.
Fig. 4 is the A direction views of Fig. 1.
Fig. 5 is the B direction views of Fig. 1.
Specific implementation mode
Below in conjunction with attached drawing, the present invention will be described in detail：Shown in Fig. 1-5, a kind of excavator of the present invention and
Dredging scheme tooth, it be by mounting seat 2,2 top of mounting seat with location hole 1 prism-shaped intermediate 3 and on
Work blocks 5 one composition of the portion with oblique top 4, the mounting seat 2 and the intermediate 6 on top are one integrally formed
Square cone table, on top the back side 7 of intermediate 6 be integrally connected to lateral triangle, perpendicular arrangement fillet
Blocks 8, top 9 and the upper end inclined-plane 10 of the intermediate 6 are in same plane, and constitute the prism-shaped intermediate 3；
It is blocky that the work with oblique top 4 is integrally connected on the same planar end surface in top of the prism-shaped intermediate 3
Body 5；4 top end face of oblique top of the work blocks 5 is in pointed cone end face, and is provided on the both sides inclined-plane of pointed cone end face more
Grain hard alloy blocks 11；Separately in two end sides 12 of 5 top end face of work blocks and the outer surface of prism-shaped intermediate 3
Weldering is connected with graininess hard alloy layer 13.
As shown in the figure, the bottom surface of the mounting seat 2 is provided with one and is in unidirectional concave lacking groove with oblique top 4
14, be provided among the bottom surface of mounting seat 2 in the mounting hole 15 that sets, the one side of the mounting seat 2 is provided perpendicular to
Concave lacking groove 14 and the located lateral hole 1 being connected to mounting hole 15；Leading flank 16 of the top intermediate 6 with respect to back side 7
It is provided with the preceding bending edges 17 more than 90 degree and is transitioned into the oblique top 4 of work blocks 5, equally in the top intermediate
Also there are a rear bending edges 18 parallel with preceding bending edges 17 in 6 back side 7 and are transitioned into the oblique top 4 of work blocks 5；
The point of interface 19 of the fillet blocks 8 of the triangle, top plan and the upper end inclined-plane of intermediate 6 is in work blocks
The centre of 5 top end faces.
The present invention using more hard alloy blocks and forms V-shape working face on the top of working face, and is set on periphery
Graininess hard alloy layer is set, the wearability working efficiency and service life of product are substantially increased, by stating the improvement of structure,
Using the design of back reinforcing rib and prism-shaped intermediate, integrally-built intensity is greatly strengthened.
