Abstract
The invention discloses an anchor retrograding device drill bit capable of safely recovering an anchor rod. The drill bit comprises a drill body and drill teeth, a through hole is formed in the center of the drill body, the upper portion of the drill body is in a horn shape, the lower portion of the drill body is a round pipe and provided with an internal thread, and the drill teeth are located on the upper portion of the drill body and uniformly distributed in a concentric circle shape. The through hole is formed in the center of the drill body, the upper portion of the drill body is in the horn shape, when the anchor retrograding device drill bit is used, the anchor rod penetrates out of the through hole and is not prone to collision with the drill teeth as the upper portion of the drill body is in the horn shape, and operation safety is further improved.
Description
Technical field
The present invention relates to a kind of instrument, in particular for dismantling the drill bit of anchor pole.
Background technology
Anchor pole is one of basic firmware of reinforcing of the conventional auxiliary security in colliery.It is typically made into shaft-like by steel wire strand strand, first punches in bearing time fixing, then injects adhesive glue in hole, then is inserted by anchor pole, and after adhesive glue solidification, anchor pole is bonded as one with bonding part.Anchor pole is the biggest in down-hole usage amount, in order to reduce expenses, reclaim anchor pole and realize the important conservation measures that recycling becomes current, owing to anchor pole is difficult to separate with bonding part, extremely it is difficult to when reclaiming anchor pole, currently mainly use hollow boring bit, the adhesive of anchor pole surrounding is destroyed, finally transfer to anchor pole.Owing to core drill is straight tube, during misoperation, it is easy to making anchor pole collide with boring tooth, the lighter breaks drill bit or burns out anchor restorer motor, severe one generation security incident.
Summary of the invention
It is an object of the invention to provide the anchor restorer drill bit of a kind of energy safe retrieving anchor pole.
The technical scheme is that and include drill body and bore tooth, described drill body center is through hole, and drill body top is horn-like, and drill body bottom is pipe and is provided with female thread, bores tooth and is positioned at drill body top uniform in concentric circular.
The present invention uses drill body center to be through hole, and drill body top is trumpet-shaped structure, and during use, anchor pole passes from through hole, and owing to drill body top is horn-like, anchor pole is difficult to and bores tooth and collide, and therefore, the safety of operation is further enhanced.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the present invention.
Fig. 2 is the sectional view of Fig. 1.
Detailed description of the invention
With embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings, but does not constitute any limitation of the invention.Shown in Fig. 1 and Fig. 2, the present invention includes drill body 1 and bores tooth 2, and described drill body 1 center is through hole, and drill body 1 top is horn-like, and drill body 1 bottom is pipe and is provided with female thread, bores tooth 2 and is positioned at drill body 1 top uniform in concentric circular.During operation, the anchor restorer drill bit of the present invention is spirally connected with anchor restorer and is integrated, and make anchor pole pass from the through hole of anchor restorer drill bit, switch on power, adhesive glue and the coal body of anchor pole surrounding are bored by anchor restorer bit, make anchor pole separate with coal body, the most easily take off anchor pole.Owing to drill body 1 top is horn-like, anchor pole is difficult to and bores tooth 2 and collide, and therefore, the safety of operation is further enhanced.
