Abstract

The invention discloses a cutting pick with a reusable tooth holder and a combined structure, which comprises a tooth holder, a welding block and an alloy head, wherein the welding block consists of two semi-ring structures, the two semi-rings of the welding block are respectively clamped on the left outer side and the right outer side of the alloy head and then are welded and fixed, and the alloy head is fixedly welded at the top end of the tooth holder. When the cutting pick works, when the alloy head is worn to a specified size, the welding block and the alloy head assembly are cut off, and the new alloy head and the new welding block assembly and the new tooth handle can be reused by cutting off the worn welding block and the worn alloy head assembly on the cutting pick, so that the purpose of reducing the consumption cost of the cutting pick is achieved.

Description

Combined structure cutting pick with reusable tooth holder

Technical Field

The invention relates to a cutting pick, in particular to a cutting pick with a reusable tooth holder and a combined structure.

Background

The traditional process and the structure have small hard alloy and are easy to wear, lose efficacy or break; the front end of the tooth body in the traditional process participates in cutting, the abrasion is fast, hard alloy is easy to lose, the abrasion of the tooth body is accelerated, the normal operation of equipment can be ensured only by replacing a cutting tooth, and the cutting tooth in the traditional process and the structure is shown in a figure 2; the traditional process and the combination of the structural hard alloy and the tooth body adopt a brazing process, the process is complex, and in order to ensure the quality of each batch, the flow line production must be adopted; the hard alloy and the tooth body of the cutting tooth used in the current market have no recycling and reusing value; the traditional process and the structure of the cutting pick have complex processes and high equipment investment cost; the cutting teeth are frequently replaced, the labor cost is high, and meanwhile, the cutting teeth are replaced by stopping the machine, so that the production progress of a user is influenced; the cutting pick hard alloy cone in the traditional process and structure is blunt, the cutting efficiency is low, the energy consumption is high, the machine load is high, and the service life of machine equipment is shortened.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a cutting pick with a reusable tooth holder and a combined structure.

In order to solve the technical problems, the invention provides the following technical scheme:

the invention relates to a cutting pick with a reusable tooth holder and a combined structure, which comprises a tooth holder, a welding block and an alloy head, wherein the welding block consists of two semi-ring structures, the two semi-rings of the welding block are respectively clamped on the left outer side and the right outer side of the alloy head and then are welded and fixed, and the alloy head is fixedly welded at the top end of the tooth holder.

As the preferable technical scheme of the cutting pick with the reusable combined structure of the tooth holder, the welding block and the alloy head are welded to form a streamline structure.

Compared with the prior art, the invention has the following beneficial effects:

when the cutting pick works, when the alloy head is worn to a specified size, the welding block and the alloy head assembly are cut off, and the new alloy head and the new welding block assembly and the new tooth handle can be reused by cutting off the worn welding block and the worn alloy head assembly on the cutting pick, so that the purpose of reducing the consumption cost of the cutting pick is achieved.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation. Wherein like reference numerals refer to like parts throughout.

In addition, if a detailed description of the known art is not necessary to show the features of the present invention, it is omitted. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Example 1

Referring to fig. 1-4, the invention provides a cutting pick with a reusable combined structure of a tooth holder, which comprises a tooth holder 1, a welding block 2 and an alloy head 3, wherein the welding block 2 is composed of two semi-ring structures, the two semi-rings of the welding block 2 are respectively clamped on the left side and the right side of the alloy head 3 and then are welded and fixed, and the alloy head 3 is fixedly welded on the top end of the tooth holder 1.

Further, the gear shank 1, the welding block 2 and the alloy head 3 are welded to form a streamline structure.

The invention has the following advantages:

1. the cutting pick adopts a combined structure;

2. the pick shank 1 of the pick can be reused;

3. the welding block 2 is of a structure of two semi-cylinders, and the welding block 2 is a whole cylinder which is cut into two semi-cylinders; see fig. 3 and 4;

4. the alloy head 3 and the welding block 2 are made into an assembly for use;

5. after the two half cylinders of the welding block 2 are clamped with the alloy heads 3, the two half cylinders are welded;

6. the alloy head 3 and the welding block 2 are made into an assembly and welded with the gear handle 1;

7. the tooth handle 1 can be reused by cutting off the worn welding block 2 and alloy head 3 assembly on the cutting tooth;

8. when the cutting pick works, when the alloy head is worn to a specified size, the welding block 2 and the alloy head 1 assembly are cut off, a new alloy head 3 and welding block 2 assembly and the tooth handle 1 can be reused by cutting off the worn welding block 2 and alloy head 1 assembly on the cutting pick, and the purpose of reducing the consumption cost of the cutting pick is achieved (as shown in figure 1).

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention.
