[0004] In order to solve the above technical problems, the utility model discloses a high-strength spiral groove cable drill rod, comprising: a rod body; a cable is arranged inside the rod body; a reinforcement part is arranged around the outer surface of the rod body, a spiral groove is arranged on the reinforcement part, and the ends of the spiral groove extend to the ends of the reinforcement part respectively, and at least two groups of cutting grooves are also arranged on the reinforcement part, and the cutting groove extends along the central axis of the rod body to the end of the reinforcement part, and the edge of one side wall of the cutting groove forms a cutting edge, and crushing teeth are also arranged in the cutting groove, and multiple groups of crushing teeth are arranged in the front part of the cutting edge.

[0005] Furthermore, the cross-sectional shape of the cutting groove is in the shape of a "check mark", and one side wall is tangent to the surface of the rod body.

[0006] Furthermore, the front portion of the cutting edge is provided with at least three linearly spaced crushing teeth.

[0007] Furthermore, the above-mentioned crushing teeth are in a pointed shape, and the head thereof is higher than the surface of the reinforcement portion.

[0008] Furthermore, the side length of the above-mentioned crushing tooth facing the cutting edge is longer than the side length of the opposite surface.

[0009] Furthermore, the height of the cutting edge is equal to the height of the crushing tooth.

[0010] Compared with the prior art, the present application can obtain the following technical effects:

[0011] The utility model provides a reinforcement part on the outer surface of the rod body, the reinforcement part improves the strength of the rod body, and a cutting groove and a spiral groove are provided on the reinforcement part. The cutting edge and the crushing teeth further drill and crush the hole wall to remove slag, so as to avoid the slag blocking and wearing the drill rod surface, and the spiral groove plays the role of slag removal.

[0012] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
