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 drag bit. A plurality of scraper blades are arranged on the bottom of a cutter head of the drag bit; each scraper blade is provided with a cutting edge; a plurality of cutting blocks are arranged at the edge of the cutter head; and each cutting block is provided with a plurality of impregnated teeth. The invention provides a diversified bit. By the new added bit, various geological conditions can be met well; cutting area is increased; mining efficiency is improved; and the quantity of dust generated in a mining process is reduced.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a scraper drill bit. Background technique [0002] A cutting bit with fins commonly used in oil drilling in upper soft formations. There are two wings, three wings, and four wings (there are also more than a dozen wing scraper bits), and the most commonly used is the three-wing scraper bit. There are two types of fin bottoms: stepped and non-stepped (divided into three types: inner step, outer step, and flat bottom), and the blade is welded with carbide or diamond. According to the needs, the scraper bit is divided into two types: coring and non-coring. Applicable formations: extremely soft, soft, medium hard. [0003] Drag bit is the earliest drill bit used in rotary drilling. It has simple structure, convenient manufacture and low cost. It is used for drilling soft formations such as mudstone and shale with drillability up to 4 grades. Due to the large pressure-bearing area ...
