Problems solved by technology

[0003] In the prior art, jumping often occurs when a rock drill is used to cut off a stone, that is, due to inaccurate positioning of the stone, although the drill bit is already on the stone, the drill bit will slip off the stone when the drill bit is driven to rotate. Test the operating level of the operator, and at the same time greatly increase the working hours of the operation, which is not conducive to the principle of economy

Abstract

The invention discloses a drill head structure for a knapping machine. The drill head structure for the knapping machine comprises a main drill head, a sleeve surrounding the main drill head and a power mechanism which drives the main drill head. The free end of the main drill head is provided with a positioning drill head. The diameter of the positioning drill head is smaller than the diameter of the main drill head. The free end of the positioning drill head is in a cone shape. According to the technical scheme, a groove which serves as a work station can be obtained on the surface of stone in advance, the main drill head can work on the work station, the working efficiency is improved, and the operating labor hours are greatly decreased.

Description

technical field [0001] The invention relates to the field of road leveling mechanical equipment, in particular to a drill bit structure of a stone drilling machine. Background technique [0002] A stone drill is a common mechanical device used to level the ground covered with stones or hard objects when laying foundations. Usually, the stone drill divides the stone into stones of different sizes through the rotation and power drive of its own drill bit, so as to achieve Requirements for flat laying of the foundation. [0003] In the prior art, jumping often occurs when a rock drill is used to cut off a stone, that is, due to inaccurate positioning of the stone, although the drill bit is already on the stone, the drill bit will slip off the stone when the drill bit is driven to rotate. Test the operating level of the operator, but also greatly increase the man-hours of operation, which is not conducive to the principle of economy. Contents of the invention [0004] In vie...
