Problems solved by technology

[0005] Although there are many types of drill bits, the actual situation in the mining process is also varied. The existing drill bits can no longer meet the diverse needs of mining work. In addition, when the drill bit is damaged, stopping the equipment to replace the drill bit also reduces the mining capacity to a certain extent. s efficiency

Abstract

The invention relates to the field of mining equipment, in particular to a projected bar drill bit; multiple strip-shaped projections are arranged on a cutting edge surface of a conical drill bit to increase a cutting area; and the projected bar drill bit comprises a drilling tool, a shank, a mounting hole, a projection, a cutting edge, a sleeve, a first limiting hole, a second limiting hole, a sleeve outer edge, a drilling handle, a pressing ball, a drill bit tail, a lifting plate, a spring and a drill bit neck. The projected bar drill bit increases the cutting area, reduces the damage degree, and guarantees the connecting firmness and the positioning accuracy.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a raised bar drill bit. Background technique [0002] Mining engineering is divided into coal mines and non-coal mines. Mining (English name: oremining) is the technology and science of mining mineral resources from the earth's crust or surface. Generally refers to the mining of metal or non-metallic deposits. In a broad sense, mining also includes the mining and beneficiation of coal and oil. Its essence is a selective collection and handling process of materials. Mining industry is an important raw material extraction industry, such as metal ore is the main raw material of metallurgical industry, non-metallic ore is chemical raw material and building materials, coal and oil are important energy sources. Most ores need to be enriched by beneficiation before they can be used as industrial raw materials. [0003] The basis of mining science and technology is the theory of rock c...
