With the development and application of new technologies, drilling machines have developed rapidly in recent years. Highlighted in the following two aspects:
1. One machine
A breakthrough in structural design, as long as the drilling tool is replaced, the machine can have the functions of a spiral, a rotary bucket, a continuous wall, a long spiral and a grab grab drill.
2. Application of electronic and electro-hydraulic proportional technology
The application of electronic and electro-hydraulic proportional technology expands the functions of the machine, improves work efficiency and reduces labor intensity.
(1) Return positioning function
When the drilling machine is drilling, there is a process of drilling - lifting - turning - throwing the soil - then turning to the original orifice - alignment - drilling again. It takes a lot of time and effort in alignment, and the manual precision is low.
(2) 3 modes
Mainly used to facilitate the operator's work and to achieve monitoring of the machine work. The three modes are: basic mode, drill pipe mode and CFA mode. These three modes can be selected by the operator as needed on the machine.
