Portable pneumatic drilling rig for soil investigation of transmission line engineering
The invention relates to the technical field of electric transmission and distribution circuit buildings, in particular to a portable pneumatic drilling rig for soil investigation of transmission line engineering. According to the portable pneumatic drilling rig, the upper end of a cutting ring shovel head is connected with the lower end of an air hammer through threads, the upper end of the air hammer is connected with the lower end of a drill rod through threads, the upper end of the drill rod and the lower end of a joint are connected together through threads, the upper end of the joint is in threaded connection with an air cock through the bottom of a handheld handle, and an air compressor is connected with the inlet end of the air cock through a rubber tube. The portable pneumatic drilling rig for soil investigation of the transmission line engineering is simple in structure, low in weight and easy to operate. In the drilling and sampling process, soil samples can be taken out easily from a cutting ring, flushing fluid is of no need, and the natural moisture content of the soil samples is prevented from being changed. All parts are connected through threaded connectors, dismounting is convenient, and big advantages for investigation of traffic inconvenience areas such as transmission line engineering mountainous areas are achieved.
