DETAILED DESCRIPTION

(5) It should be understood that orientations or positional relationships indicated by the terms “length”, “width”, “upper”, “lower”, “front”, “rear”, “left”, “right”, “vertical”, “longitudinal”, “horizontal”, “top”, “bottom”, “inside”, “outside”, etc. are the orientations or positional relationships shown based on the accompanying drawings, and are merely for facilitating describing the present disclosure and simplifying the description, rather than indicating or implying that the devices or elements must have particular orientations, and be constructed and operated in particular orientations. Thus, it cannot be construed as a limitation to the present disclosure.

Embodiment 1

(6) As shown in FIG. 1 to FIG. 3, a spiral impact drilling machine applicable to rock and soil includes a power distribution system, an air compression system, a rock chiseling part, a soil drilling part, a gear 9, a drill rod 8, and a drill bit at the bottom of the drill rod. The rock chiseling part includes a rock chiseling shell, an air cylinder 1. An air pipe 2 is arranged at the top of the air cylinder 1. A hole is formed in the bottom of the air cylinder 1. A piston 3 is arranged in the air cylinder 1. The top of the piston 3 is fixedly connected with to a shaft of a turbine fan blade 4. The bottom of the piston 3 is fixedly connected to a force transferring component 5. The soil drilling part includes a soil drilling shell and a motor 6. The force transferring component 5 is arranged in the soil drilling shell, and the motor 6 is arranged in the force transferring component 5. The inner part of the gear 9 is in nested connection with the drill rod 8. The outer part of the gear 9 is in engaged connection with the bottom of the force transferring component 5 and the motor 6. The bottom of the gear 9 is fixedly connected to the drill rod 8 through a stress component. The drill bit includes a spiral drill bit 11. The bottom of the spiral drill bit 11 is connected to a high-strength rock drilling drill bit 12.

(7) The drill rod is connected and lengthened through screw threads 10. The drill rod is combined and assembled according to a drilling depth, so as to meet a requirement on hole depth.

(8) The bottom of the drill rod 8 is connected to the drill bit 11 through the screw threads 10. The drilling machine further includes a dismounting device matched with the drill bit. The spiral drill bit 11 is engaged with the dismounting device, and the drill rod and the drill bit are automatically dismounted by controlling the drill rod to rotate in an opposite direction.

(9) The rock chiseling shell is connected to the soil drilling shell by bolts.

(10) During work, when the high-strength rock chiseling drill bit 12 is in contact with a soil stratum, the motor 6 is started. The motor 6 drives the spiral drill bit 11 and the high-strength rock chiseling drill bit 12 to rotate through the rotation of the drill rod 8, so as to drill a hole. When the high-strength rock chiseling bit 12 is in contact with a rock stratum, the air compression system (pumping in or pumping out air) controls the turbine fan blade 4 to drive the piston 3 to rotate through the air pipe 2, and simultaneously controls the piston 3 to move up and down, so that the force transferring component 5 drives the drill rod 8 to rotate, drives the spiral drill bit 11 and the high-strength rock chiseling drill bit 12 to rotate, and simultaneously transfers an impact load to the stress component 7. The high-strength rock chiseling drill bit 12 is driven to rotate and chisel the rock through the drill rod 8.
