Description

Bucket tooth and bucket with impact resistance

Technical Field

The utility model belongs to the technical field of mining excavator parts, and particularly relates to a bucket tooth and a bucket with impact resistance.

Background

The excavator is an earthwork machine which uses a bucket to destroy and excavate engineering materials such as soil, sand and gravel, loads a bucket middling work Cheng Wuliao into a transport vehicle or unloads the engineering materials to a storage yard, and the bucket mainly comprises a tooth base plate, a bottom plate, a side plate, a wall plate, bucket teeth, tooth bases, guard plate main body parts and the like, wherein the bucket teeth are positioned at the tip end part of the bucket and are in direct contact with and excavate the main parts of the materials. During the use process of the excavator, the bucket teeth are firstly in direct contact with engineering materials to destroy the main components of the structure of the engineering materials,

the bucket teeth are often subjected to strong impact caused by hard obstacles such as broken stones and the like in the working process, and the bucket teeth are easy to damage due to the impact. The patent application for the impact-resistant low-carbon alloy steel excavator bucket aims at the problem, the application number is 202220937195.2, the patent application is named as an impact-resistant low-carbon alloy steel excavator bucket, an elastic component is arranged between the bucket teeth and the bucket to buffer, and the impact force of the bucket teeth is reduced. However, the bucket still has the problem that the bucket teeth are easy to wear, and the bucket teeth do not have impact resistance.

Disclosure of Invention

The utility model aims at the defects that the bucket tooth with impact resistance can release impact force, has high impact resistance and effectively prolongs the service life of the bucket tooth.

The first aspect of the utility model provides a bucket tooth with impact resistance, which comprises a bucket tooth base body similar to a pyramid, wherein the bucket tooth base body is provided with a plurality of side surfaces, at least one side edge of each side surface is curved, a through hole is arranged on the bucket tooth base body, the central axis of the through hole is perpendicular to the central axis of the bucket tooth base body, and the through hole is close to the bottom surface of the bucket tooth base body.

Further, the through hole is elliptical.

Further, the side faces are wedge-like; the included angle between the side face and the central axis of the bucket tooth matrix is 25-65 degrees.

Further, the bucket tooth base body is bird beak-like.

A second aspect of the utility model provides a bucket comprising a bucket body provided with a tooth body as defined in any one of the preceding claims.

The beneficial effects are that:

the utility model reduces the resistance during excavation and improves the capability of damaging engineering materials by arranging the conical bucket tooth base body. The side edges of the side surfaces are set to be curves, so that cutting resistance during excavating materials is further reduced, the wear resistance of the surfaces of the bucket teeth is improved, and the working efficiency of the bucket teeth is improved. Through setting up the through-hole, when the bucket tooth contacted hard material, produced great impact stress, partial impact stress can transfer to through-hole department, reduces stress concentration phenomenon, makes bucket tooth itself possess impact resistance, prolongs bucket tooth's life.

Detailed Description

The technical solutions of the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, the utility model provides a bucket tooth with impact resistance, which comprises a bucket tooth base body 1 similar to a pyramid, wherein the pyramid can crush hard engineering materials, and is convenient for excavation. The tooth base 1 has a plurality of side surfaces 11, the number of the side surfaces 11 being at least 4, and the greater the number of the side surfaces 11, the smaller the surface excavation resistance of the tooth base 1. At least one side of each side 11 is curved, so that a certain curvature exists on the surface of the bucket tooth base body 1, cutting resistance is reduced during excavation, impact of materials on the bucket tooth base body 1 is reduced, a through hole 12 is formed in the bucket tooth base body 1, the central axis of the through hole 12 is perpendicular to the central axis of the bucket tooth base body 11, and the through hole 12 is close to the bottom surface of the bucket tooth base body 1.

Referring to fig. 1 and 2, in one particular embodiment, the through-hole 12 is elliptical. The oval through holes 12 can effectively release stress, and meanwhile, the structural stability of the bucket tooth base body 1 is not damaged.

Referring to FIG. 2, in one embodiment, the sides 11 are wedge-like, with the wedge-like sides 11 having high stability, making the tooth base 1 stronger. The included angle between the side face 11 and the central axis of the bucket tooth matrix 1 is 25-65 degrees, the bucket tooth matrix 1 in the range can effectively crush materials, and meanwhile, the bucket tooth matrix 1 has good stability.

Referring to fig. 1 or 2, in one embodiment, the tooth base 1 is shaped like a beak, preferably a beak like a woodpecker, and the shape is a bionic design, so that the tooth base 1 has high impact resistance.

Referring to fig. 3, the present utility model also protects a bucket including a bucket body 2, and the bucket body 2 is provided with the tooth body 1 of any one of the above. The bottom surface of the bucket tooth base body 1 is connected with the bucket base body 2, and the bucket tooth base body 1 is provided with a through hole 12 which can release impact stress and enable the bucket to have stronger impact resistance.

The foregoing disclosure is illustrative of the present utility model and is not to be construed as limiting the scope of the utility model, which is defined by the appended claims.
