Geological survey drilling rig

Abstract

The invention provides a geological survey drilling rig, and belongs to the technical field of geological survey tools. The geological survey drilling rig comprises a main drill pipe, a pneumatic impactor and a secondary drill pipe which are arranged in sequence from bottom to top, and an air passage in the secondary drill pipe, the pneumatic impactor and the main drill pipe communicates with an air compressor through an air channel. A fixing rod is arranged on the outer wall of the secondary drill pipe, a drill bit is arranged at the lower end of the main drill pipe, and a dust recovery device is arranged above the fixing rod. The geological survey drilling rig utilizes the air compressor to provide power, compressed air is blown towards the drill bit along the air passage in the secondary drill pipe, the pneumatic impactor and the main drill pipe, and the pneumatic impactor drives the drill bit to drill holes in an impact mode, so that manpower is saved. At the same time, the air compressor is discharged through the air passage, the effects of cooling the drill bit and blowing out dust are achieved, drilling is performed while punching, and the drilling efficiency is improved. The dust generated in the drilling process can be recovered by the dust recovery device, the dust is prevented from floating around and affecting the observation of operators, and the clean working environment and the personal health of the operators are ensured at the same time.

Description

technical field

[0001] The invention belongs to the technical field of geological survey tools, and more specifically relates to a geological survey drill. Background technique

[0002] In geological exploration, it is often applied to drilling equipment. The drilling equipment in the prior art mainly uses the drilling rig to drive the drilling tool to drill into the ground to break the rock at the bottom of the hole, and is used to drill cores, ore cores, cuttings, gaseous samples, and liquid samples. samples and other physical geological data to ascertain the conditions of underground geology and mineral resources. Existing drilling equipment consists of a derrick, a drilling rig, a drill pipe, a drilling tool, a water pump, etc., mainly using a rotary drilling tool and a water circulation method. The drilling process is to install the drilling tool on a hollow drill pipe, which is driven by the drilling rig through the drill pipe. The rotation of the drilling tool is com...
