Further improvement as technique scheme:
The two ends end face of described reaming bar welds with the sidewall of drilling rod and the inside wall of waistband respectively and is connected, and its solder side is inside two straight plates of described fagging and the disposed inboard of swash plate, and after reaming bar is welded and fixed, described solder side is hidden inside its end face;
The two ends of described swash plate are fixedly welded on two straight plate medial surfaces of fagging, and its solder joint is positioned at the connection corner point inside described hollow flow passage;
Described cross bar comprises three.
The beneficial effects of the utility model are as follows:
In the utility model use procedure, owing to adopting the reaming bar of triangular structure, the reaming bar of relative traditional cylindrical structure, improves the frictional force to saprolite ore, and raising blends, reaming effect; The solder side of the weld of the reaming bar of triangular structure and drilling rod and waistband and solder joint are all hidden in inside end face, avoid solder and the external world directly to contact producing rubbing, and improve the stable connection of reaming bar; Cross bar is double-decker, and is provided with alloy block, and it is equivalent to carry out secondary agitation to earth rubble and blend, and avoids bulk earth rubble to exist, compares original single support rail, greatly improves reaming efficiency and improves stable connection.
