A portable rotary drilling rig

Abstract

This utility model relates to a portable rotary drilling rig, including a fixed plate. A mounting frame and a side plate are fixedly installed on one side of the fixed plate. A lifting assembly is provided between the mounting frame and the side plate. A slider is provided between the mounting frame and the side plate through the lifting assembly. A fixed frame is fixedly installed on the top side of the slider. The fixed frame is U-shaped. A collection box is fixedly installed on the top side of the fixed frame. Two base plates are fixedly installed on the bottom side of the mounting frame. When dust generated by the threaded drill bit needs to be absorbed, the fan is started. The operation of the fan will drive two suction nozzles to transport the dust generated by drilling to the collection box through two hoses. Each suction nozzle is equipped with a filter screen on one side. The filter screen can block dirt and other impurities, thereby preventing dirt from entering the hose and causing the hose to become clogged. By using the two suction nozzles to absorb dust during the drilling process, the dust content in the air can be effectively reduced, reducing the risk of operators inhaling dust.
