The utility model has the advantages of reasonable design, have the benefit of the drill core that conveniently changes the drill bit and conveniently ejecting blocking.
However, in the prior art, the problems that the noise is large during operation and the joint still makes abnormal sound due to the lack of shock absorption and noise reduction measures at the joint of the coring pipe and the handle part exist.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a highway road surface detects coring bit for solve the current junction of coring bit and stalk portion and lack the measure of making an uproar of bradyseism, lead to the noise too big, the junction still sends the problem of abnormal sound.
In order to solve the problem, the utility model provides a highway road surface detects coring bit, stalk portion and cylindric core taking pipe including the cylinder tube-shape, the upper end of stalk portion is provided with the flange, be provided with the lug between the interior edge of stalk portion and the flange, the lug shape is cellular, the lower extreme of core taking pipe is provided with the concave edge corresponding with the flange, be provided with concave block between interior edge of core taking pipe bottom and the concave edge, first pinhole has been seted up on the flange, the second pinhole has been seted up on the concave edge, first pinhole passes through the pivot and is connected and make core taking pipe and stalk portion be connected as an organic wholely with the second pinhole.
The utility model provides a highway road surface detects coring bit still has following technical characteristic:
furthermore, a drill bit is arranged on one side, away from the handle, of the coring pipe.
Furthermore, a thread groove is arranged on the coring pipe.
Further, the shape and the size of the convex block and the concave block are matched.
Further, the lug is annularly arranged around the flange.
Further, the concave blocks are annularly arranged around the concave edge.
The utility model discloses following beneficial effect has: evenly be provided with lug and concave piece on the flange through at the stalk portion and the concave edge of coring, can be so that link up more firmly between the two to lug and concave piece are cellular, utilize cellular strong stability that possesses, and the bearing capacity is strong and the thermal-insulated advantage of sound insulation, slow down the problem of vibrations and noise between coring and the stalk portion.
