Embodiment Construction

[0027] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] see Figure 1-6 As shown, a dry-type internal powder discharge drill bit includes a drill bit 1, a cutting edge 3, a drill rod 6 and a through hole 2. The drill bit 1 is externally connected with several helical cutting edges 3, and the drill bit 1 is externally connected to several cutting edges 3. Several through holes 2 are arranged between them. When the drill bit 1 rotates, the cutting edge 3 can increase the working efficiency of the drill bit 1. Dust can enter the drill bit 1 and the drill pipe 6 through the t...

Abstract

The invention discloses a drill bit with dry internal drillings discharge and is intended to solve the problem that an existing drillings-discharge drill bit with simple structure is low in drillingsdischarging efficiency, cannot provide dry discharging for drillings, is not convenient enough to change during use and is high in post-damage maintenance cost. The drill bit comprises a bit body, a plurality of cutting edges in spiral shape, a shank and a plurality of through holes; the cutting edges are connected to the outer side of the bit body; the through holes are arranged in the outer sideof the bit body between the cutting edges; one end of the bit body is fitted with a top cap; the top cap is fixedly connected with the bit body via a screw hole and a screw; a plurality of conical protrusions are evenly connected to the edge, close to grooves, of the top cap. The middle of the other end of the bit body is connected with a fixing terrace; the bit body is connected with the shank via the fixing terrace; the outside of the other end of the shank is connected with a hex terrace; a second inner tube is connected to the middle of the inside of the end, close to the hex terrace, ofthe shank; an inner ring is connected to each inner side of the second inner tube.

Description

technical field [0001] The invention relates to a drill bit, in particular to a dry internal powder discharge drill bit. Background technique [0002] A drill is a tool used to drill through holes or blind holes in solid materials and to ream existing holes. Commonly used drills mainly include twist drills, flat drills, center drills, deep hole drills and casing drills. Although reaming drills and countersinking drills cannot drill holes in solid materials, they are also customarily classified as drill bits. At the same time, in the mining industry, drill bits are often used to mine various ores, improve the mining efficiency of ores, and save mining costs. There are various kinds of drill bits used in ore, and there are many kinds of drill bits, which are indispensable equipment in the ore industry. [0003] But existing powder discharge drill still has certain deficiency in use. The existing powder discharge drill bit has a simple structure, and the efficiency of powde...
