Straight-line directional hole digger

Abstract

The invention discloses a straight-line directional hole digger. The straight-line directional hole digger comprises a loader body and a hole digging device, wherein the hole digging device comprises a connecting support, a fixed sleeve, a telescopic oil cylinder, a sliding sleeve, a hydraulic motor, a supporting drum base, a connecting shaft assembly and a drill bit, the connecting support is connected with the loader body through a hinge pin, the connecting support is welded to the fixed sleeve, a sliding sleeve is arranged in the fixed sleeve, the telescopic oil cylinder is arranged in the sliding sleeve, the base of the telescopic oil cylinder is connected with an oil cylinder fixing base of the fixed sleeve through a hinge pin, the rod end of the telescopic oil cylinder is connected with the sliding sleeve through a hinge pin, the sliding sleeve is fixedly connected with the supporting drum base, the supporting drum base is fixedly connected with the connecting shaft assembly, and the connecting shaft assembly is fixedly connected with the hydraulic motor. The straight-line directional hole digger solves the problem that when the hole digger is used for digging a hole, the hole is oval and not a straight line and the problem that the drill bit and a drill stem are prone to being bent if the hole digging depth is too large, the service life of the drill steam is greatly prolonged, and the quality of the hole and the hole drilling and digging efficiency are improved.

Description

technical field [0001] The invention relates to a hole digging (pit) machine, in particular to a linear directional hole digging machine. Background technique [0002] At present, the old-fashioned hole-digging machines powered by loaders are not oriented in a straight line. When digging holes, the drill bit descends in a curve. As a result, the drill bit and drill rod are easily bent under the influence of bending force during hole-digging, which greatly reduces its life. , and the hole dug out is elliptical, which is neither practical nor beautiful; and because the force on the drill rod affects the rotation speed of the drill bit, the working time is greatly increased, and the drilling efficiency of the hole is seriously reduced. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a linear orientation hole digging machine, which fills the domestic gap that the current hole digging machine p...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a linear orientation hole digging machine, which fills the domestic gap that the current hole digging machine powered by a loader cannot be oriented in a straight line when digging holes, and solves the problem of this type of hole digging machine. The problem that the pit is elliptical and not straight when digging the hole solves the problem that the drill bit and the drill pipe are easily bent if the depth of the hole is too deep, and greatly improves the life of the drill pipe, the quality of the pit and the drilling efficiency
