Abstract

The invention relates to the technical field of drilling machines, in particular to a small multi-function drilling machine. The small multi-function drilling machine comprises a base, a mast and a power device are arranged on the base, a pedestal is arranged at the bottom of the power device, and a power head is arranged at the bottom of the pedestal. A clamping device is arranged at the bottom of the power head and comprises a clamping head, a plurality of first grooves are formed in the clamping head, and a second annular groove is formed in the outside of the clamping head. Inserting rods are arranged between the second annular groove and the first grooves in a communicating mode, clamping blocks matched with the first grooves are arranged in the first grooves, and the inserting rods are arranged on the backs of the clamping blocks and penetrate through inserting holes. Lantern rings are arranged at the ends of the inserting rods in a wedge-shaped matched mode, the contacting faces of the inserting rods and the lantern rings are matched in a threaded mode, and the lantern rings are arranged in the second annular groove in a sleeved mode. The inserting rods are sleeved with springs, one ends of the springs are connected with the clamping head, the other ends of the springs are connected with the bottoms of the first grooves, and a drill bit is arranged in the clamping head in an inserting mode. According to the small multi-function drilling machine, requirements of countryside well drilling are met, the clamping effect is good, and an anti-dust device is additionally arranged for avoiding flying dust.

Description

technical field [0001] The invention relates to the technical field of drilling rigs, in particular to a small multifunctional drilling rig. Background technique [0002] Due to its high degree of mechanization and automation, flexible and convenient on-site shifting, high hole forming efficiency, high axial pressure, high construction efficiency, and environmental protection, the drilling rig is suitable for the geological conditions in most areas of my country with different drilling tools, and has become a suitable construction tool. The most ideal construction machine for hole-forming operations in pile foundation engineering. In rural areas, people usually need to use drilling rigs to drill wells. Large-scale drilling rigs cannot be used, and a small drilling rig is needed. Contents of the invention [0003] The purpose of the present invention is to solve the shortcoming that large drilling rigs are not suitable for drilling wells in rural areas in the prior art, and ...
