Geological exploration reamer

Abstract

The invention relates to a geological exploration reamer. The geological exploration reamer comprises a waistband and a drill rod, wherein the drill rod is fixedly connected to the waistband through cross rods; two adjacent reaming rods are fixedly connected with each other via connection rods located at the middle positions of the reaming rods; fixing rods are connected with the drill rod via support rods; alloy blocks are arranged on the outer side walls of the reaming rods, the lower side wall of the waistband, the lower side walls of the connection rods and the lower side walls of the support rods. The geological exploration reamer has the beneficial effects that a plurality of reaming rods are connected together via the connection rods, so that the force applied to one reaming rod can be distributed to other reaming rods; the force applied to each reaming rod can be reduced; the support rods are used for supporting the reaming rods; the drill rod support the reaming rods to a certain degree; the reaming rods is further supported; meanwhile, the alloy blocks are arranged on the connection rods and the support rods, the soil cutting effect is improved.

Description

technical field [0001] The invention relates to the technical field of geology, in particular to a hole reamer for geological exploration. Background technique [0002] The reamer used for geological exploration in the prior art includes a belt and a drill pipe. The drill pipe is a hollow structure, which is fixed to the center of the belt by means of a cross bar support. The set reaming rod, the reaming rod is also a hollow structure, the outer wall of the reaming rod and the lower end surface of the belt are evenly distributed with alloy blocks, the reaming rod is connected with the drill rod, and when the reamer rotates at high speed to ream the hole, the The upper end is injected with clear water, and the clear water flows out from the lower end of the drill pipe and the side wall of the reaming rod to reduce the resistance of the gravel and soil. This reamer for geological exploration has the following disadvantages: the reaming rod has a cylindrical structure, and its...

Problems solved by technology

This reamer for geological exploration has the following disadvantages: the reaming rod has a cylindrical structure, and its friction with soil and gravel is small, and the chopping force for soil and gravel is insufficient, and the friction of the alloy block alone is not enough to dislodge the soil. All chopped, that is, there are large pieces of soil and gravel that are easy to get stuck between the belt and the cross bar, causing damage to the reamer and other parts, resulting in low feeding efficiency; the end of the reaming rod with a cylindrical structure and the drill The connection area between the outer wall of the rod and the inner wall of the belt is small, and can only be fixed by welding the outer surface, that is, the solder is exposed on the outside. When rotating at high speed, the solder rubs against the soil and gravel, and its wear resistance is poor. The welding area is small, so the reaming rod is easy to fall off, so it needs to be repaired in time, which reduces the engineering efficiency
