Description

High wear-resisting equipment of mining pick Technical Field The utility model relates to the technical field of mining equipment, in particular to mining tooth cutting high-wear-resistance equipment. Background Mining picks are key cutting tools specifically designed for use in mining operations such as coal mines, metal mines, and the like. The structure is generally composed of a cemented carbide cutting head, an alloy steel tooth body and a connecting part, and the components together ensure high strength, high wear resistance and high impact toughness of the cutting pick. The main function of the mining pick is to cut and crush hard materials such as rock, coal beds and the like in the mining process. Through the mode of rotation or impact, the cutting pick can effectively crush materials, so that mining work is propelled. In coal mining, picks are widely used on drums of coal mining machines for cutting coal seams, and in metal mines they are commonly used in heading machines and crushers for crushing hard ores. The mining equipment provided with the cutting pick is easy to wear due to huge friction caused by contact with the coal seam. Therefore, a new solution is needed. Disclosure of utility model The utility model aims to provide mining cutting tooth high-wear-resistant equipment, which solves the problem that the mining equipment provided with cutting teeth is easy to wear due to huge friction caused by contact with a coal bed. The mining tooth cutting high-wear-resistant equipment comprises an outer disc, wherein a plurality of groups of fixing seats are arranged at the edge and the outer surface of the outer disc, pick bodies are arranged in the fixing seats, an inner disc is arranged on the surface of the outer disc, a mounting plate is arranged in the inner disc, the mounting plate is fixed between the mounting plate and the inner disc through bolts, auxiliary teeth and double-headed teeth distributed on the periphery of members are arranged on the surface of the mounting plate, a mounting seat is arranged on the side surface of the outer disc and is connected with a power executing mechanism of a coal mining machine, a mounting groove is arranged in the fixing seats, the pick bodies comprise mounting columns inserted in the mounting groove, a connecting seat is arranged on the upper portion of each mounting column, a connecting column is arranged on the upper portion of each connecting column, and smooth transition is formed between each tooth body and each connecting column in an integrated mode.
