[0008] As a preferred solution of the present invention, the outer structure of the earth-breaking tooth piece is a triangular pyramid structure design, and the earth-breaking tooth piece and the bucket tooth head are an integrally formed structure design.

[0009] As a preferred solution of the present invention, the bucket tooth head and the earth-breaking tooth piece are made of metal tungsten, and the bucket tooth head, the earth-breaking tooth piece and the bucket tooth body are formed by hot-melt forging.

[0010] As a preferred solution of the present invention, the top side surface of the bucket tooth body is designed as an arc-shaped structure, and.

[0011] As a preferred solution of the present invention, the bucket tooth external cavity and the bucket tooth body are designed as an integrally formed structure.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. In the present invention, the bucket tooth head and the earth-breaking tooth piece are made of metal tungsten, thereby increasing the hardness of the bucket tooth breaking end and preventing the bucket tooth from being worn and broken due to long-term work. In addition, the outer structure of the bucket tooth head is a quadrangular pyramid structure, and the outer structure of the earth-breaking tooth piece is a triangular pyramid structure. Therefore, when the bucket tooth is used for excavating earth, the bucket tooth is inserted into the soil like a blade or an arrow. In summary, the bucket tooth is sharper and the earth-breaking and excavation effects are better. BRIEF DESCRIPTION OF THE DRAWINGS

However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0020] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0023] A sharp bucket tooth comprises a bucket tooth external cavity 1, a connecting hole 2 is opened on the side wall of the bucket tooth external cavity 1, a bucket tooth body 3 is arranged on the front of the bucket tooth external cavity 1, a bucket tooth head 4 is arranged on the front of the bucket tooth body 3, and earth-breaking tooth pieces 5 are arranged on the left and right sides of the bucket tooth head 4.

[0024] In this embodiment, the outer structure of the bucket tooth head 4 is a quadrangular pyramid structure design, and the front end of the bucket tooth head 4 is a flat arc structure design, the outer structure of the earth-breaking tooth piece 5 is a triangular pyramid structure design, and the earth-breaking tooth piece 5 and the bucket tooth head 4 are an integrally formed structure design, the bucket tooth head 4 and the earth-breaking tooth piece 5 are all made of metal tungsten material, and the bucket tooth head 4, the earth-breaking tooth piece 5 and the bucket tooth body 3 are hot-melt forged, the top side surface of the bucket tooth body 3 is an arc structure design, the bucket tooth external cavity 1 and the bucket tooth body 3 are an integrally formed structure design, the bucket tooth head 4 and the earth-breaking tooth piece 5 can be made of metal tungsten material, thereby increasing the hardness of the bucket tooth breaking end and preventing the bucket tooth from wear and breakage due to long-term work, and the outer structure of the bucket tooth head 4 is a quadrangular pyramid structure design, and the outer structure of the earth-breaking tooth piece 5 is a triangular pyramid structure design, so that when the bucket tooth is breaking the soil with an excavator, the bucket tooth can be inserted into the soil like a blade or an arrow.

[0025] The working process of the present invention is as follows: first, the bucket tooth external cavity 1 is installed with the excavator's digging claw. When the digging claw digs and breaks the soil, the bucket tooth head 4 will break the soil first, and then the breaking tooth piece 5 will break the soil on both sides of the bucket tooth head 4. Then the bucket tooth body 3 also enters the soil, and the soil breaking work is completed at this time. The bucket tooth head 4 and the breaking tooth piece 5 can be made of metal tungsten material, thereby increasing the hardness of the bucket tooth breaking end and preventing the bucket tooth from being worn and broken due to long-term work. The outer structure of the bucket tooth head 4 is a four-sided pyramid structure design, and the outer structure of the breaking tooth piece 5 is a three-sided pyramid structure design, so that when the bucket tooth is used to break the soil by the excavator, the bucket tooth can be inserted into the soil like a blade or an arrow. In summary, the bucket tooth can be sharper and the soil breaking and excavation effects are better.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
