Description
Technical Field
The utility model relates to a coal mining mechanism, concretely relates to pick.
Background
In the operation of a coal mining machine and a heading machine, a cutting tooth is used as a cutter for directly cutting a coal bed or breaking rocks, the working condition is severe, so that the cutting tooth is easy to damage, most of abnormal wear failure is manifested by the cracking and abrasion of the front end of a tooth body, and an alloy cutter head loses protective support too early, so that the cutting tooth falls off. In order to solve the problems, the existing method is to weld a plurality of wear-resistant strips on the outer side, and has large welding workload and complex process.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a cutting pick aiming at the defects of the prior art.
The purpose of the utility model is realized through following technical means:
the drilling bit comprises a base body and a drilling bit arranged at the top of the base body, wherein the base body is composed of a front umbrella part and a rear mounting rod, the outer side of the front end of the umbrella part is covered with a circular truncated cone-shaped cylinder wall, and the cylinder wall is welded on the umbrella part.
In the preferred scheme, the cylinder wall is made of wear-resistant materials, and the upper end face and the lower end face of the cylinder wall are welded on the umbrella part along the circumferential direction.
Compared with the prior art, the utility model has the following obvious advantage: compared with the welding in the prior art, the welding has the advantages of multiple wear-resistant strips, small workload of welding the cylinder wall, simple process, integral stress of the cylinder wall during working and high reliability.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be described in further detail with reference to the following description and embodiments with reference to the accompanying drawings: in the figure, 1 drill, 2 cylinder wall, 3 umbrella part, 4 mounting rod.
The cutting pick comprises a base body and a drill bit 1, wherein the base body is composed of a front umbrella part 3 and a rear mounting rod 4, the front end of the umbrella part 3 is provided with a groove, the drill bit 1 is tightly embedded into the groove, the outer side of the front end of the umbrella part 3 is covered with a circular truncated cone-shaped cylinder wall 2, the cylinder wall 2 is formed by welding wear-resistant materials, and the outer side of the front end of the umbrella part 3 is welded on the outer side of the front end of the umbrella part along the circumferential direction to form a. The cutting pick is integrally stressed during working, has good wear resistance and reliable working, protects the drill bit and the base body and greatly prolongs the service life of the cutting pick. The diameter of the bottom of the umbrella part 3 is larger than that of a common cutting pick, so that the tooth sleeve part can directly contact with a coal bed, the tooth sleeve is protected, and the service life of the tooth sleeve is prolonged. Compared with the prior art in which a plurality of wear-resistant strips are welded on the outer side of the umbrella part, the umbrella part is large in size and longer in service life.
