anti-blocking auger

Abstract

The invention belongs to the technical field of twist drills, and particularly relates to an anti-blocking twist drill. The anti-blocking twist drill comprises a driving ring sleeve, a driving gear, afirst fixing plate, a second fixing plate, a third fixing plate, a fourth fixing plate, a fifth fixing plate, a shaft sleeve, a driving shaft, a first cone tooth combination, a second cone tooth combination, a third cone tooth combination, a fourth cone tooth combination and the like. According to the anti-blocking twist drill, repetitive dislocation movement is always kept between a first spiralsheet and a second spiral sheet through a speed-change double-crank mechanism, in this way, clay is difficult to adhere to the first spiral sheet, the situation that the twist drill is blocked by theclay is avoided accordingly, and the drilling depth of the twist drill is greatly benefited. The anti-blocking twist drill is simple in structure and has the good using effect.

Description

technical field [0001] The invention belongs to the technical field of auger drills, in particular to an anti-blocking auger drill. Background technique [0002] At present, in the process of traditional drilling, auger drills are generally used for drilling. Under the drive of the motor, the drill bit is used to drill the hole, and then the hole is enlarged under the rotation of the helical piece, and the rotation of the helical piece and the drill bit can be better. It is beneficial to drilling; but during the drilling process, due to the helical rotation of the helical flakes, the soil in the soil layer will stick to the helical flakes. As the drilling deepens, a large amount of clay is easily blocked between the spiral flakes, thus affecting To the progress of drilling, in order to prevent the clay from clogging the auger, it is necessary to design an anti-blocking auger. [0003] The present invention designs an anti-blocking auger to solve the above problems. Conten...
