Abstract
The utility model provides an excavator bucket tooth with a convex pointed layer. The excavator bucket tooth comprises a bucket tooth main body and a protective layer, wherein the protective layer is formed on the outer edge of the bucket tooth main body; the upper end of the bucket tooth main body is provided with a protective bump; the protective bump is arranged on the bucket tooth main body in an inverted trapezoid form; the bucket tooth main body is provided with a convex pointed layer; the convex pointed layer is provided with a projecting spine; and the length of the convex pointed layer decreases in sequence from top to bottom. The utility model aims to design the excavator bucket tooth with the convex pointed layer; the service life of the bucket tooth is protected effectively via the protective layer on the bucket tooth main body, so that the bucket tooth has higher wear resistance; the bucket tooth can be kept in a sharp state via the convex pointed layer on the bucket tooth main body; and the excavator bucket tooth is simple in structure, and has a long service life.
Description
Technical field
The utility model relates to a kind of excavator accessory, particularly a kind of excavator bucket teeth that has the spur layer.
Background technology
Excavator bucket teeth is the vitals on the excavator, no matter building, construction of the highway, the construction of water conservancy works aspect all plays an important role, force analysis bucket tooth work plane excavates thing with quilt and contacts, different its stressing conditions difference of working stage in a complete mining process, when the crown position at first contacts the material surface, because speed is very fast, the bucket tooth nose part is subjected to stronger impact, if the intensity of bucket tooth is low, will produce plastic strain in the tip, along with the increasing of excavation depth, the bucket tooth stressing conditions can change to some extent, when bucket tooth cutting material, bucket tooth and material generation relative motion produce very big forward extrusion power on the surface, thereby produce bigger frictional force between bucket tooth work plane and material, if material is harder rock piece, concrete etc., frictional force will be very big, and the result that this process acts on repeatedly is at bucket tooth work plane generation surface abrasion in various degree, and then the bigger ditch dug with a plow of the generation degree of depth.
Bucket tooth commonly used inserts difficulty of material, and perhaps insertion is not dark, and digging efficiency is low when excavating; and energy consumption is bigger in the use, and efficient is also lower, and the increase of crack conditions usually causes equipment downtime to increase; add the expense of changing bucket tooth, make use cost increase greatly.
Summary of the invention
For addressing the above problem; the utility model discloses a kind of excavator bucket teeth that has the spur layer, be arranged on the overcoat on the bucket tooth main body, effectively protect the application life of bucket tooth; make it more wear-resistant, the spur layer that is arranged on the bucket tooth main body can make bucket tooth keep sharp state.
The utility model provides a kind of excavator bucket teeth that has the spur layer; comprise the bucket tooth main body; be arranged on the overcoat of described bucket tooth main body outer rim; be provided with the protection projection in described bucket tooth main body upper end; described protection projection is down trapezoidal and is arranged on the described bucket tooth main body; described bucket tooth main body is provided with the spur layer, is provided with bur at described spur layer, and the length of described spur layer from top to bottom reduces successively.A kind of excavator bucket teeth that has the spur layer of the purpose of this utility model design; be arranged on the overcoat on the bucket tooth main body; effectively protect the application life of bucket tooth; make it more wear-resistant; the spur layer that is arranged on the bucket tooth main body can make bucket tooth keep sharp state, and this utility model is simple in structure, and long service life; in the process of using, the bucket tooth tip keeps sharp state.
The utility model discloses a kind of a kind of improvement that has the excavator bucket teeth of spur layer, described spur layer is at least 3 layers.This improvement spur layer is set at least 3 layers, does not very fewly have a good excavation effect, and the spur layer that is arranged on the bucket tooth main body can make bucket tooth keep sharp state, makes that the destructive power to soil layer increases greatly.
The utility model discloses a kind of a kind of improvement that has the excavator bucket teeth of spur layer, described bur is inverted triangle.This improvement bur is set to inverted triangle, makes bucket tooth guarantee sharp state, the resistance when reducing to excavate.
A kind of excavator bucket teeth that has the spur layer of the purpose of this utility model design; be arranged on the overcoat on the bucket tooth main body; effectively protect the application life of bucket tooth; make it more wear-resistant, the spur layer that is arranged on the bucket tooth main body can make bucket tooth keep sharp state, and arranging of protection projection prevents that effectively hard thing from damaging bucket tooth; this utility model is simple in structure; and long service life, in the process of using, the bucket tooth tip keeps sharp state.
