Abstract

The utility model discloses a pick of dentate shank repeatedly usable's integrated configuration, including dentate shank, welding piece and alloy head, wherein the welding piece comprises two semi-ring structures, and two semi-rings of welding piece block respectively and weld fixedly after the alloy head left and right sides two outsides, and the alloy head is fixed to be welded on the top of dentate shank. The utility model discloses in at pick during operation, treat that the alloy head wearing and tearing to the specification size, cut off welding block and alloy head subassembly, new alloy head and welding block subassembly, the toothholder can realize used repeatedly through the welding block and the alloy head subassembly that have worn and torn on the excision pick, reaches the purpose that reduces pick consumption cost.

Description

Combined structure cutting pick with reusable tooth holder

Technical Field

The utility model relates to a pick, in particular to but pick of shank reuse's integrated configuration.

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 to-be-solved technical problem of the utility model is overcome prior art's defect, provide a pick of shank reuse's integrated configuration, the utility model discloses in at pick during operation, treat that the alloy head wearing and tearing to the specified size, cut off welding block and alloy head subassembly, new alloy head and welding block subassembly, the shank can realize used repeatedly through the welding block and the alloy head subassembly that have worn and torn on the excision pick, reaches the purpose that reduces pick consumption cost.

In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model relates to a pick of dentate shank repeatedly usable's integrated configuration, including dentate shank, welding piece and alloy head, wherein the welding piece comprises two semi-ring structures, two semi-rings of welding piece block respectively and weld fixedly after the alloy head left and right sides two outsides, the fixed top of welding in the dentate shank of alloy head.

As the utility model discloses a preferred technical scheme of pick of shank repeatedly usable's integrated configuration, shank, welding piece and alloy head welding form streamlined structure.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses in at pick during operation, treat that the alloy head wearing and tearing to the specification size, cut off welding block and alloy head subassembly, new alloy head and welding block subassembly, the toothholder can realize used repeatedly through the welding block and the alloy head subassembly that have worn and torn on the excision pick, reaches the purpose that reduces pick consumption cost.

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

As shown in fig. 1-4, the utility model provides a pick of dentate shank repeatedly usable's integrated configuration, including dentate shank 1, welding block 2 and alloy head 3, wherein welding block 2 comprises two semi-ring structures, and two semi-rings of welding block 2 block respectively and weld fixedly behind the two outsides of alloy head 3 left and right sides, and alloy head 3 fixed welding is on the top of dentate shank 1.

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

The utility model has the advantages of it is following:

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).
