Abstract
The utility model relates to rock drilling machinery technology and in particular to a novel pneumatic propeller for down hole drill comprising a vane type pneumatic motor, a planetary gear train decelerator, and a brake structure, thus achieving a propeller which is tight in structure, smaller in size, and light in weight. The mechanical processing and installation of the utility model are easier than conventional propeller which is composed of a piston type pneumatic motor and gear worm, thus reducing cost of mechanism. The propeller of the utility model is disposed at the lower end of the drilling arm which lowers the center of gravity of the drilling arm. The utility model can reduce swing of drilling arm in rock drilling and boring which is equal to reducing vibration generated by shock wave. Discharged air flow can blow powder brought by the air flow discharged by an impact device from the down hole drill. The utility model can prolong service time of the down hole drill, and increase practicability and reliability of the entire drill.
