After the high-speed rotation of the hydraulic motor 42 is decelerated by the speed reducer 43, the power of the speed reducer 43 is input into the power box 44, and the rotary motion of the drilling machine during drilling is realized. And the pressurizing oil cylinder 5 pressurizes the rotary power head 4, and pressure is transmitted to the telescopic drill rod 7. Because the telescopic drill rod 7 rotates, the outer clamp 73 of the first section of drill rod 71 and the rotary power head 4 generate positive pressure, and the positive pressure generates friction force, and because the pressurization oil cylinder 5 performs pressurization action on the rotary power head 4, the friction force realizes the feeding motion of the drilling work of the telescopic drill rod 7. The connecting plate 45 is fixed with the power box 44 and guides along a guide rail when the drilling pressure and the power head pulling work conditions are met. The follow-up frame 3 is an auxiliary device for a rotary power system and a drill rod 71 to work, one end of the follow-up frame 3 is provided with a bearing 31 and is connected with the drill rod 71 through a bolt 32, and the follow-up frame plays a role in rotary support of the drill rod 71; the other end of the follow-up frame 3 is provided with a guide groove 33 which is slidably connected with the mast guide rail and is a guide part for the operation of the drill rod 71. The soil sampler 8 is a key component for determining soil sampling properties. The soil sampler 8 can be configured according to different geological conditions, so that the drilling machine can work efficiently under most geological conditions. The utility model discloses, simple structure, the action is more nimble, and the rig size is little, can adapt to the constrictive complex environment in place, has stronger stability, can take darker original state soil sample, can reduce artifical intensity of labour for reconnaissance efficiency. The problem of traditional rig drilling rod 71 carry out manual concatenation installation, because the place is restricted can only give up the drilling sample or select open place nearby, the place restricted area adaptability is weak is solved.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
