Abstract

The invention provides an excavation drill high in precision and efficiency. The excavation drill comprises a connecting device, a fixed bolt, a drilling structure, an installing groove, a heat dissipation window, a center drill, a main drill and an auxiliary drill. The connecting device is installed on the upper portion of the drilling structure through the fixed bolt, the installing groove is disposed in the upper portion of the outer side of the drilling structure, the heat dissipation window is arranged on the lower portion of the installing groove, the center drill is installed at the bottom of the drilling structure, and the main drill or the auxiliary drill is installed on the outer side of the drilling structure. By arrangement of the connecting device, the drilling structure and the center drill, the installation stability of the drilling structure can be improved, the fastness degree in drilling work is enhanced, the failure rate of the drilling structure is reduced, drilling excavation precision and working efficiency are improved, and the excavation drill is flexible to install and dismantle, convenient and swift to maintain and long in service life.

Description

Technical field [0001] The invention belongs to the technical field of drilling equipment, and particularly relates to an excavating bit with high precision and high efficiency. Background technique [0002] At present, with the continuous development of my country's economy, in the field of construction engineering, in order to improve work efficiency and reduce the labor intensity of workers in the construction of power systems, tunnels, drilling, excavation and underground building systems, most of them use excavation and drilling for construction. The specific operation, especially in oil drilling, mountain road construction has a greater application. However, most of the existing excavation and drilling tools in use use integrated rock drilling bits, which are simple in structure, short in service life, need to be replaced frequently, and have high operating costs. If they are used for a long time, they will be reduced due to wear. Work efficiency. [0003] Therefore, technol...
