Abstract

The hand-held excavator was particularly designed for artificial excatating pile drilling. It consisted of a motor, a gear reducer, a drill stem, a frame and a drill bit. The drill stem was an important component of the hand-held excavator. In order to improve the drilling speed of the excavator, the structure of the drill stem was designed, besides, the forces on the leaf blade, the pressure losss and the best conveying speed of the pneumatic conveying and so on were calculated, and the fan was selected. The research indicates that the drill stem can suitable for the hand-held excavator.
