Anti-bend drill

Abstract

The invention discloses an anti-bending ground auger. The anti-bending ground auger comprises an auger rod. The anti-bending ground auger is characterized in that a power mechanism making the auger rod rotate is arranged at the upper end of the auger rod; an auger bit is arranged at the lower portion of the auger rod; an auger rod tip for fixed point positioning and guiding is arranged at the lower end of the auger bit; a compression ring is arranged at the position, close to a pull ring, of the auger rod; an ejection ring is arranged at the portion, at the lower portion of the compression ring, of the auger rod; a breast board capable of increasing bearing pressure due to increase of the contact area with soil is arranged between the ejection ring and the compression ring; an auger rod blade is arranged at the position, between the auger rod and the ejection ring, of the auger rod. In the ground drilling process, the direction of the ground auger can be adjusted through an adjusting handle on the breast board, it is guaranteed that the direction of the ground auger and the direction of a pull line are kept consistent, and the ground auger is prevented from being bent. The anti-bending ground auger is easy and convenient to operate in the ground press-in and ejection processes. Damage to the ground auger is low. The service life of the ground auger is long. The ground auger is more firmly fixed underground due to the effect of the breast board.

Description

technical field [0001] The invention relates to the technical field of power transmission line erection engineering equipment, in particular to an anti-bending ground drill. Background technique [0002] In the prior art, the ground drills used in power transmission line engineering are all vertical structures. When in use, they are drilled vertically into the ground. The annular part of the ground drill exposed on the ground is used to fix the guy wires. The specification requires an angle of 45° to the ground. After the part of the ground drill exposed to the ground is pulled by the cable, the drill pipe will bend, which reduces the service life of the drill and the safety of construction. At the same time, the drill in the prior art is under pressure It is time-consuming and labor-intensive when entering and ejecting the ground, and it is easy to cause damage to the drill pipe, and the drill pipe is not firmly fixed underground.
