Embodiment Construction

[0024] In view of the above problems, the object of the present invention is to provide a rotary drill with multiple sub-drills. On the basis of traditional rotary drills, a plurality of sub-drills are added. The number, installation position and orientation of the sub-drills can be adjusted according to actual conditions, greatly improving Provides the convenience and versatility of a rotary drill.

[0025] In order to achieve the above object, the present invention adopts the following technical solutions

[0026] A rotary drill with multiple sub-drills, which includes a drill shank 1, a drill neck 2, a cutter head 3, a main cutting edge 4, a base 5, a sub-drill 6, a nozzle 7, a sub-drill neck 61, a sub-drill shank 62, and a sub-drill edge 63.

[0027] The drill shank 1 is fixedly connected to the drill neck 2, the drill neck 2 is fixedly connected to the cutter head 3, the center of the surface of the cutter head 3 is provided with a main cutting edge 4, and the surface of...

Abstract

The invention relates to the field of mining equipment, in particular to a rotating drill bit with multiple drill sub-bits. According to the rotating drill bit with the multiple drill sub-bits, the multiple drill sub-bits are added on the basis of a traditional rotating drill bit, the number, the installation positions, the directions of the drill sub-bits can be adjusted according to actual conditions, so that convenience and versatility of the rotating drill bit are greatly improved. The drill bit is diversified; due to the arrangement of the main and sub drill bits, the rotating drill bit is suitable for various geologic conditions; the cutting area is increased, and the mining efficiency is improved; the number of nozzles is increased, so that the dust generation amount in the mining process can be effectively decreased.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a rotary drill with multiple sub-drills. Background technique [0002] In mining equipment, the drill bit is a very important component, and the drill bit is the tool on the drill, drilling machine, and drilling machine. Can create holes in workpiece or rock. Existing drill bits mainly include twist drills, flat drills, deep hole drills, reaming drills, center drills, hollow drills, etc. [0003] During the use of the drill bit, when drilling steel parts, please ensure sufficient cooling capacity and use metal cutting fluid; good drill pipe rigidity and guide rail clearance can improve the drilling accuracy and the life of the drill bit; ensure that the magnetic base and the workpiece When drilling a thin plate, the workpiece should be reinforced, and when drilling a large workpiece, please ensure that the workpiece is stable; at the beginning and end of drilling, the feed rate ...
