Abstract

The invention discloses a portable core sampling drill. The portable core sampling drill comprises a handle, wherein a power supply device is mounted in the handle and electrically connected with a transmission clutch through a wire, a power switch is arranged below the right side of the handle, a power head is mounted on the right side of the transmission clutch, a drill pipe is arranged on the right side of the power head, a bellows is mounted on the right side of the drill pipe, vent holes are formed in the right side in the bellows which is fixedly connected with a core barrel, dust removal holes are formed above and below the core barrel, a rock breaking drill bit is mounted on the right side of the core barrel and movably connected with the core barrel, and a chromium-manganese tooth head is arranged on the right side of the rock breaking drill bit. The portable core sampling drill is reasonable in structure, easy to operate, small in size, portable, high in drilling efficiency and suitable for field work, guarantees high rock pillar forming rate and has good marketing value.

Description

technical field [0001] The invention belongs to the technical field of sampling drills, in particular to a portable core sampling drill. Background technique [0002] The core is a cylindrical rock sample taken out of the hole by using an annular core drill bit and other coring tools according to the needs of geological exploration work or engineering. The ore-bearing rock or ore taken from the ore body or bed of a solid mineral is called a core. Cores are important physical geological data for studying and understanding underground geology and mineral conditions. Drilling in a complete rock formation, because the cores taken out are relatively complete, and there is no difference between the core recovery rate and the complete rate, so it is generally not paid much attention to. However, when drilling in weak and broken complex formations, it is very important to distinguish recovery rate and integrity rate. [0003] Existing core sampling rigs are often relatively large...
