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

Embodiment Construction

[0020] In view of the above problems, the purpose of the present invention is to provide a raised bar drill bit, which is provided with several bar-shaped projections on the cutting edge surface of the conical drill bit, which increases the cutting area, and has a better use effect with the improved sleeve.

[0021] In order to achieve the above purpose, the present invention adopts the following technical solutions

[0022] A raised strip drill bit, which includes a drill 1, a shank 2, a mounting hole 3, a protrusion 4, a cutting edge 5, a sleeve 6, a first limit hole 7, a second limit hole 8, and the outer edge of the sleeve 9. Drill handle 10, press ball 11, drill tail 12, lift plate 13, spring 14, drill neck 15.

[0023] The drill 1 is integrated with the handle 2, the top of the cutting edge 5 is provided with a mounting hole 3, the handle 2 is fixedly connected with the cutting edge 5 through the mounting hole 3, and the cutting edge 5 is provided with a number of protru...

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 strip drill bit. Background technique [0002] Mining engineering is divided into coal mines and non-coal mines. Mining (English name: ore mining) is the technology and science of mining mineral resources from the crust or the surface. Generally refers to the mining of metal or non-metallic deposits, and mining in a broad sense also includes the mining and beneficiation of coal and oil. Its essence is a selective collection and handling process of materials. The mining industry is an important raw material extraction industry. For example, metal ores are the main raw materials of the metallurgical industry, non-metallic ores are chemical raw materials and building materials, and 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] Mining science and technology are based o...
