Embodiment Construction

[0011] Below with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between the various parts, the role and working principle of the various parts, etc., will be further described. detailed description of the .

[0012] Such as figure 1 As shown, the use method of the front and rear bidirectional anti-jamming drill bits is the same as that of ordinary drill bits. When using, the front and rear bidirectional drill bits are driven by the drill rod 1 to drill holes, and the front drill teeth 4 are used for drilling. When the drill bit needs to be withdrawn, the drill rod does not need to be changed. 1 rotation direction, so that the front and rear two-way drill bit rotates and exits, the drill blade on the rear drill tooth 3 grinds the fragments stuck on the drill bit, turns the fragments into powder, and uses the gap betwe...

Abstract

The invention discloses a front-back two-way anti-drill-jamming drill bit, and belongs to the technical field of underground coal mine drilling. The front-back two-way anti-drill-jamming drill bit comprises a drill rod, a drill bit seat, front drill teeth and rear drill teeth, wherein one end of the drill rod is fixedly connected to the tail of the drill bit seat, the front end of the drill bit seat is fixedly connected with the front drill teeth, and the rear part of the drill bit seat is fixedly connected with the rear drill teeth. The front-and-back two-way anti-drill-jamming drill bit effectively avoids jamming of a drill, can drill under complex geological conditions, avoids hole wall scouring caused by the jamming of the drill, effectively solves the problems of hole collapse and drill loss, and improves drilling construction quality and efficiency.

Description

technical field [0001] The invention relates to the technical field of underground drilling in coal mines, in particular, the invention relates to a front-back bidirectional anti-jamming drill bit. Background technique [0002] In the construction process of coal mine underground roadway, bolting and anchoring and grouting support technology are needed. With the popularization of bolting and grouting and anchoring technology and the wide application of directional drilling technology, drill stuck and lost drill occur in the drilling construction process. , Collapsing holes and other quality problems have been highlighted, bringing large economic losses to the enterprise every year. Especially in the drilling construction process in special areas such as geological fracture zones and abnormal ground pressure areas, the phenomena of drill stuck, lost drill and hole collapse seriously affect the progress of the project and the safety of production.
