The eccentric disk 42 is axially connected to the output shaft of the adjustment motor 41, and the drilling motor 31 is eccentrically fixed to the eccentric disk 42.

[0024] Reference Figure 1 , 2A slag discharge structure 5 is provided on one side of the drill bit 32, and the slag discharge structure 5 includes a slag extraction pipe 51, a blower 52, a lifting slider 53 and a latch 54. The slag extraction pipe 51 is accommodated in the inner side of the drill tube 1 and is staggered with the drill bit 32. The lifting slider 53 is fixed to the slag extraction pipe 51 and is lifted and connected to the drill tube 1; the latch 54 is penetrated through the drill tube 1 and can be respectively penetrated through the upper and lower ends of the lifting slider 53; the blower 52 is fixed to the drill tube 1, and an exhaust duct 9 extending toward both sides is provided on the blower 52, one side of the exhaust duct 9 is located above the slag extraction pipe 51, and the slag extraction pipe 51 is lifted and connected to the exhaust duct 9 of the blower 52, and the air outlet of the blower 52 faces the exhaust duct 9 opposite to the slag extraction pipe 51; when the slag extraction pipe 51 descends and approaches the drill bit 32, the blower 52 uses the siphon principle to drive the soil to rise and discharge.

[0025] Reference Figure 2 , 3 A control structure 6 close to the drill bit 32 is provided at the bottom of the slag extraction pipe 51, and the control structure 6 includes a slag extraction hose 61, a limit joint plate 62 and a driving pull wire 63. The slag extraction hose 61 is fixed and connected to the bottom of the slag extraction pipe 51, and an anti-friction port 8 is fixed at the bottom of the slag extraction hose 61; the limit joint plates 62 are rotatably connected to each other, and one end of the limit joint plate 62 is fixed to the slag extraction pipe 51, and the other end is fixed to the side wall of the slag extraction hose 61, the side walls of the limit joint plate 62 abut against each other, the side walls of the limit joint plate 62 are inclined, and the extended planes intersect on the side close to the drill bit 32; the driving pull wire 63 is fixed to the side of the slag extraction hose 61 opposite to the limit joint plate 62, and the driving pull wire 63 is lifted and lowered and connected to the outer wall of the slag extraction pipe 51.

[0026] Reference Figure 1 , 2 The slag extraction pipe 51 is connected to a grouting pipe 7, which is fixed to a lifting slider 53 and connected to the lower end of the slag extraction pipe 51, so that the slag extraction hose 61 at the bottom of the drill tube 1 has a larger diameter. At the same time, the grouting pipe 7 is close to the bottom of the slag extraction pipe 51, so that the cleaning distance of the mud is short and the cleaning is convenient.

[0027] The working process of the present application is as follows: the drill barrel 1 is hoisted by the lifting ear 2, the rotary control handle 10 is pushed to rotate the drill barrel, and the rotating drill bit 32 digs the ground to form a circular hole. The hole diameter can be changed by controlling the adjustment motor 41 to adapt to drill barrels 1 of different sizes and closely match the size of the drill barrel 1, so that the drill barrel 1 stably supports the side wall of the borehole.

[0028] When the slag needs to be discharged, the lifting slider 53 is moved and the positioning pin 54 is positioned to lower the slag extraction pipe 51, and then the driving pull wire 63 is pushed downward. The driving pull wire 63 drives the slag extraction pipe 51 to bend inward, thereby achieving a larger range of operation of the slag extraction pipe 51. At the same time, the limiting node plate 62 limits the slag extraction hose 61 to prevent it from contacting the drill bit 32.
