A helical drill machine is a drill with helical blades, including a drill frame with guides, a reduction box that slides up and down the guides, the reduction box connected to the power input and output shafts, the other end of the power input shaft connected to a hydraulic motor, and the other end of the power output shaft connected to the drill rod, with the drill bit at the lower end of the drill rod.
The main components of the spiral drill rig are the drill mast column, which features a track and a sliding speed reducer that can move up and down. The reducer connects to the power input and output shafts, with the power input shaft connected to a hydraulic motor at one end and the power output shaft connected to the drill rod at the other, which in turn connects to the drill bit at its lower end. The vertical movement of the drill rod is achieved through a drive mechanism that operates the speed reducer, facilitating rapid downward force and drilling. The speed reducer can slide up and down along the tracks of the drill rig frame to ensure the perpendicularity of the borehole. The drill rod is a spiral blade type, allowing soil to be returned to the ground along the blades during drilling. The power output shaft is a hollow shaft, with the top opening capable of connecting to concrete pouring equipment for concrete pouring.
