Description
Technical field:
The utility model relates to the technical field of spiral drilling machine, more specifically to the drilling rod of structure optimization on a kind of spiral drilling machine.
Background technology:
Spiral drilling machine, as the term suggests be a kind of auger with helical blade, it is generally applied to building site boring and uses.During spiral drilling machine, take the earth of cutting out of bottom surface by the helical blade on drilling rod.And front spiral drilling machine be generally dry drilling, easily cause helical blade to be out of shape during dry drilling, simultaneously large with the frictional force of earth, more easily wear and tear.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provides the drilling rod of structure optimization on a kind of spiral drilling machine, and the helical blade of its drilling rod forms muscle groove, intensity is larger, carry water-supply-pipe simultaneously, dry drilling is changed into wet boring, the wearing and tearing of helical blade can be reduced.
Technology solution of the present utility model is as follows:
The drilling rod of structure optimization on a kind of spiral drilling machine, comprise the body of rod, the body of rod is by splined shaft, drill bit and stud composition, drill bit and stud are molded over the two ends up and down of splined shaft respectively, splined shaft is plugged with spline housing, the outer wall of spline housing is welded with helical blade, helical blade forms the muscle groove prolonging helical blade helix and extend, spiral helicine water-supply-pipe is welded with in the muscle groove of helical blade, the upper end of water-supply-pipe is fixedly connected with water pipe head, the lower end of water-supply-pipe is welded with spiral helicine guiding round bar, guiding round bar is weldingly fixed in the muscle groove of helical blade lower end, the bottom of guiding round bar bottom and helical blade all forms the guide angle of inclination, the tube wall of water-supply-pipe lower end forms several weep holes.
The top of described body of rod stud is bolted with rig connector, and stud is inserted with spacer and is bolted with clamp nut, and the upper and lower end face of spacer is resisted against on clamp nut and spline housing respectively.
The external diameter of the diameter of described guiding round bar etc. and water-supply-pipe, on helical blade, the cross section of muscle groove is circular arc, and the arc radius of muscle groove equals the external diameter of water-supply-pipe.
The beneficial effects of the utility model are:
It is rectified and improved the helical blade of existing spiral drilling machine, set up the intensity that muscle groove strengthens helical blade, resistance to deformation intensity increases, helical blade is provided with efferent duct simultaneously, efferent duct can use at spiral drilling machine water spray, thus dry drilling is changed into wet boring, the wearing and tearing of helical blade can be reduced.
