The invention relates to a tooth for an excavator and a dredging machine, in particular to a mechanical bucket tooth which is used for being arranged on a bucket of the excavator and the dredging machine and used for excavating soil and the like, and belongs to the technical field of the excavator and the dredging machine engineering.
Background
In many working occasions in earthwork, especially in the working occasions of river channel excavation, dredging, coastal beach embankment and the like, an excavator is needed; the excavator mainly utilizes the ultra-long arm bucket or the bucket to carry out the operation, so that the performance of the bucket or the bucket directly influences the production capacity of the excavating and dredging machine, the power consumption, the working stability and the service life of other related parts.
The bucket teeth installed on the excavator bucket or the bucket are mainly formed by a bucket tooth body and a hard alloy tool bit in an integrated mode. Because the head carbide tool bit of bucket tooth direct contact earthwork, therefore need have certain wear resistance, but current bucket tooth structure is not very reasonable, and the intensity of bucket tooth still is not enough, consequently, actual use's life-span is short, need often change, influences earthwork operation, reduction in efficiency to still can increase use cost.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide the excavator and the dredging machine tooth which are simple and reasonable in structure, convenient to use and install, high in strength and fastness, and capable of improving the wear resistance of the surface of a product and prolonging the service life and the service efficiency of the product.
The invention aims at completing the technical scheme that the tooth for the excavator and the dredging machine is composed of an installation base with a positioning hole, a prismatic middle body at the upper part of the installation base and a working block body with an inclined top end at the upper part, wherein the installation base and the middle body are integrally formed into a square frustum body, the back side surface of the middle body is integrally connected with a lateral triangular narrow strip block body which is vertically arranged, the top end of the narrow strip block body and the inclined surface at the upper end of the middle body are positioned on the same plane, and the middle body is formed; the working block body with the inclined top end is integrally connected with the same flat end surface of the upper part of the intermediate body; the top end of the working block body is a pointed cone end surface, and a plurality of hard alloy blocks are arranged on the inclined surfaces at two sides of the pointed cone end surface; and granular hard alloy layers are welded on both end sides of the top end face of the working block body and the outer surface of the intermediate body.
As preferable: the bottom surface of the mounting base is provided with a notch groove which is in the same direction as the inclined top end, the middle of the bottom surface of the mounting base is provided with an internally arranged mounting hole, and one side surface of the mounting base is provided with a transverse positioning hole which is perpendicular to the notch groove and communicated with the mounting hole; the front side surface of the middle body opposite to the back side surface is provided with a front bending edge which is larger than 90 degrees and transits to the inclined top end of the working block body, and the back side surface of the middle body is also provided with a back bending edge which is parallel to the front bending edge and transits to the inclined top end of the working block body; and the junction point of the top end plane of the triangular narrow strip block body and the upper end inclined plane of the intermediate body is positioned in the middle of the top end surface of the working block body.
The invention belongs to an improvement on the prior art, and has the characteristics of simple and reasonable structure, convenient use, high strength, high fastness, long service life and high service efficiency of the product, and the like, and the wear resistance of the surface of the product can be improved.
