Description

Technical Field

[0001] This utility model relates to the field of rotary drilling tooth technology, and in particular to a wear-resistant alloy rotary drilling tooth. Background Technology

[0002] Wear-resistant alloy rotary drilling teeth are the core cutting components of rotary drilling rigs. Made of high-strength wear-resistant alloy materials, they are primarily used for drilling operations under various geological conditions. Through a specially designed tooth structure and carbide cutter head, they achieve cutting and breaking of rock and soil layers under the power of the drilling rig. This component possesses excellent wear resistance and impact resistance, effectively meeting the drilling needs of rock layers of varying hardness, significantly improving construction efficiency and extending service life. It is widely used in foundation treatment operations in fields such as building pile foundations, bridge engineering, and mining. However, existing rotary drilling teeth still suffer from low strength, inability to achieve efficient progressive breaking, and the inability to replace damaged parts locally.

[0003] Therefore, it is essential to invent a wear-resistant alloy rotary drilling tooth. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a wear-resistant alloy rotary drilling tooth, solving the issues of low strength, inability to achieve efficient progressive crushing, and inability to partially replace damaged rotary drilling teeth. A wear-resistant alloy rotary drilling tooth includes a connecting support body, a stabilizing tooth seat, a mounting connection groove, a mounting support base, a crushing tooth body, and a rock-breaking tooth tip. The stabilizing tooth seat is fixedly installed on the top of the connecting support body, and the mounting connection groove is formed on the surface of the connecting support body. The mounting support base is fixedly installed below the connecting support body. The crushing tooth body is slidably installed on the outside of the mounting support base, and the rock-breaking tooth tip is fixedly installed on the bottom of the crushing tooth body.

[0005] The mounting support base includes a supporting steel ingot, a connecting seat, and a positioning mounting body. The connecting seat is fixedly installed on the top of the supporting steel ingot, and the connecting support body is fixedly installed above the connecting seat. The positioning mounting body is fixedly installed below the supporting steel ingot, and a crushing tooth body is slidably installed on the outer side of the positioning mounting body.

[0006] The crushing tooth body includes a rock-crushing tooth, a splitting tooth, a crushing tooth, and a mounting and connecting base, with the splitting tooth located above the rock-crushing tooth and the crushing tooth located above the splitting tooth; the mounting and connecting base is fixedly installed inside the crushing tooth and the rock-crushing tooth, splitting tooth, and crushing tooth are connected as a whole by bolts.

[0007] The supporting steel ingot inside the mounting base is a cylindrical tungsten-cobalt hard alloy, and the diameter of the positioning mounting body is the same as that of the supporting steel ingot, and it is connected to the supporting steel ingot as a whole; the positioning mounting body adopts several mutually parallel trapezoidal grooves.

[0008] The rock-crushing teeth, splitting teeth, and crushing teeth inside the crushing tooth body are all made of tungsten-cobalt hard alloy blocks, and the internal design of the splitting teeth and crushing teeth has several parallel trapezoidal protrusions; the outer sides of the rock-crushing teeth, splitting teeth, and crushing teeth are all provided with ridges, and the ridges of the rock-crushing teeth are relatively gentle, the ridges of the splitting teeth are moderate, and the ridges of the crushing teeth are the sharpest.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. The installation support base of this utility model provides high-strength support through the support steel ingot, and uses the connecting seat to achieve a stable connection with the connecting support body to transmit drilling pressure and torque; the trapezoidal groove design of its positioning installation body not only provides precise sliding guidance for the crushing tooth body, but also absorbs the impact force of rock strata through buffer displacement, while the hard alloy material effectively resists wear; in addition, the modular structure design facilitates quick disassembly and maintenance, and is a key component to ensure efficient crushing and long service life of the rotary drilling tooth.

[0011] 2. The crushing tooth body of this utility model achieves efficient and progressive crushing through a three-stage gradient hard alloy tooth body design consisting of rock crushing teeth, splitting teeth, and pulverizing teeth. Its sliding fit structure with the mounting support base can dynamically buffer the impact of rock strata. At the same time, the modular mounting connection base design facilitates the quick replacement of worn parts, and has the comprehensive performance advantages of impact resistance, wear resistance, and easy maintenance.
