PURPOSE: A drilling device for tree injection using a grass eliminator is provided to bore a hole for tree injection by using a drill exposed through the through hole on a cap member and rotated in high speed. CONSTITUTION: A drilling device for tree injection using a grass eliminator comprises a drill holder(110), a guide pipe(120), a cap member(130), and a spring member. The drill holder is mounted on the outer casing(222) of a power transmission unit(220) and the drill of the drill holder is rotated by the torque transferred from the rotary shaft of the power transmission unit. The guide pipe is assembled with the outer surface of the drill holder to be reciprocated. The cap member is assembled with the opened front end of the guide pipe. The spring member supports the guide pipe elastically. |
