Description
Technical field
The utility model is specifically related to a kind of construction work drill, belongs to building engineering construction technical field of tools.
Background technology
In Building Construction, often need to carry out bore operation, such as: when construction of buildings, need to hole in ground; Substantially all adopt drill to complete bore operation in current engineering, but current drill is when carrying out bore operation, as drilling depth is excessively dark, when silt in ground cannot be discharged in time, a large amount of silt can increase the load of drill, be easy to cause the ossified of drill, even can damage the driving mechanism driving drill to rotate.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind ofly can discharge unnecessary silt in time when holing, thus reduces the load of drill, the construction work drill avoiding driving mechanism to damage.
Construction work drill of the present utility model, comprise sleeve pipe, be rotatably connected to the drilling rod in sleeve pipe and be fixedly connected on the drill bit of drilling rod lower end, the through hole having and arrange along casing length direction is run through in the middle part of described sleeve pipe, described drilling rod grafting in through-holes, bearing is provided with between described drilling rod and the inwall of through hole, described drill bit internal is provided with the cavity of a lower ending opening, the lower surface of described drill bit is provided with the sawtooth of circumference distribution, described sawtooth is arranged on the outside of cavity, the lower end of described drilling rod extend into cavity inside and is positioned on the periphery wall of the drilling rod of cavity inside and is provided with auger, discharge opening is provided with in the drill bit of described cavity top, tapping channel is provided with in described sleeve pipe.
Construction work drill of the present utility model, wherein, from top to bottom expansion formation is round table-like gradually for the external diameter of described drill bit.
Construction work drill of the present utility model, wherein, the inwall of described its lower end is provided with the inclined-plane matched with drills outer circumference wall.
Construction work drill of the present utility model, wherein, described discharge opening is in oblique setting from inside to outside.
The utility model beneficial effect: of the present utility model a kind of hole time unnecessary silt can be discharged in time, thus reduce the load of drill, the construction work drill avoiding driving mechanism to damage, during use, sleeve pipe is connected on the pedestal of driving mechanism, drilling rod is connected on the clutch end of driving mechanism, during work, driven the rotation of drill bit by the rotation of drilling rod, drill bit realizes the bore operation to ground, by arranging cavity in drill bit, the drilling rod of cavity inside arranges auger, discharge opening is set in the drill bit of cavity top and tapping channel is set in sleeve pipe, when drill bit rotational, auger realizes the lifting to silt in ground, discharged by discharge opening by the silt promoted, the silt of discharging from discharge opening is then discharged by tapping channel, by the setting of said structure, silt unnecessary in ground can be discharged in time, thus effectively can reduce drill bit, the load of drilling rod and driving mechanism, avoid the damage of the driving mechanism of the utility model and driving utility model works.
