Abstract

The invention relates to a reamer belt structure with a reaming function. The reamer belt structure comprises a belt of an annular structure, multiple welding grooves are symmetrically arranged in the inner wall of the belt, multiple reaming strips are arranged on the outer wall of the belt, water leading grooves are arranged in the belt and on two sides of each reaming strip along the reaming strip, an alloy block group is arranged between every two adjacent reaming strips, and each alloy block group comprises multiple alloy blocks arranged along the corresponding reaming strip. The reamer belt structure is simple in structure, and has the advantage that reaming efficiency is improved highly due to the fact that the reaming strips are combined with the alloy blocks as compared with a traditional reamer belt; by the welding groove structure, welding with a connecting rod is facilitated, and connection strength is improved; flow guide grooves arranged in the reaming strips are combined with the water leading grooves of the belt, so that reaming resistance is reduced while reaming efficiency is improved.

Description

technical field [0001] The invention relates to the field of geological exploration equipment, in particular to a hole reamer. Background technique [0002] The reamer is a tool for reaming holes in geological exploration, including a belt and a drill pipe. The drill pipe is set in the center of the belt, and the two are connected by a connecting rod. The belt is a ring structure, and the connecting rod is welded to the inner wall of the belt. . The disadvantages of the belt in the prior art are: the welding operation between the inner wall of the belt and the connecting rod is inconvenient, and the connection stability is not high; The reaming resistance of the waist belt is relatively high. Contents of the invention [0003] The applicant researches and improves the above-mentioned shortcomings in the prior art, and provides a reamer belt structure with a reaming function, which is firmly connected with the connecting rod, has a reaming function, and improves the reame...
