Abstract
The utility model relates to a coal pick, including the base member with set up in the drill bit at base member top, the base member comprises preceding umbrella portion and hou mian installation pole, the front portion of umbrella portion is through thermal treatment's high strength round platform portion, the outside at the rear portion of umbrella portion is equipped with the wear-resisting strip of a plurality of slopes, is the shrink waist between the front portion and the rear portion of umbrella portion. The coal cutting pick has high integral hardness, good wear resistance and reliable work, and the wear-resistant strips participate in cutting coal, thereby improving the coal mining efficiency.
Description
Technical Field
The utility model relates to a coal mining mechanism, concretely relates to coal 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 problem, the prior method is to weld a plurality of wear strips on the outer side, wherein the wear strips are only limited at the front end, and other parts are not protected.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a coal cutting pick aiming at the defects of the prior art.
The purpose of the utility model is realized through following technical means:
the base body is composed of a front umbrella part and a rear mounting rod, the front part of the umbrella part is a high-strength circular table part subjected to heat treatment, a plurality of inclined wear-resistant strips are arranged on the outer side of the rear part of the umbrella part, and a contraction waist part is arranged between the front part and the rear part of the umbrella part.
Preferably, the wear strips are welded to the outside of the rear portion of the umbrella portion.
Preferably, the bottom surface of the umbrella part is provided with a plurality of grooves.
Compared with the prior art, the utility model has the following obvious advantage: the coal cutting pick has high integral hardness, good wear resistance and reliable work, the wear-resistant strips participate in cutting coal, and the coal mining efficiency is improved.
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, a drill bit, 2 circular table parts, 3 umbrella parts, 4 wear-resistant strips, 5 mounting rods and 6 grooves.
The coal 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 5, the front end of the umbrella part 3 is provided with a groove, the drill bit 1 is tightly embedded into the groove, the front part of the umbrella part 3 is a high-strength circular table part 2 which is subjected to heat treatment, the process is to harden the front part of the base body by using a heat treatment technology, a wear-resistant layer is formed, the wear resistance is improved, the outer side of the rear part of the umbrella part 3 is provided with a plurality of inclined wear-resistant strips 4, the wear-resistant strips are welded on the umbrella part 3, the umbrella part is protected, and a contraction waist part is arranged. The bottom surface of the umbrella part 3 is provided with a plurality of grooves, so that the installation rod is conveniently pried down from the pick box.
