Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following detailed description of the present invention with reference to the accompanying drawings and embodiments is to be understood that the embodiments described herein are only used for explaining the present invention, and are not used for limiting the present invention.

As shown in fig. 1-4 a road engineering detects coring bit of usefulness, including drill bit body 1, drill bit body 1's bottom is drill bit portion 2, and drill bit body 1's top is connecting portion 3, two sets of row's core groove 4 that extend to the lower extreme by drill bit body 1 upper end have been seted up to the symmetry on drill bit body 1's the lateral wall, through setting up row's core groove 4, appear blocking the stem messenger in drill bit body 1, can follow row's core groove 4 and insert the body of rod and release the stem of card in the drill bit, because row's core groove 4 extends to the lower extreme from drill bit body upper end, the body of rod can directly push away the stem to drill bit body 1 near the place of bottom.

It is worth noting that coring bit in this embodiment has predetermine the row core structure that can follow row core groove 4 up-and-down motion in its inside, can realize pushing out the stem of card in drill bit body 1 inside through row core structure of predetermineeing to it is more convenient to operate, when the drill bit bore the core operation, because the stem gets into drill bit body 1 in, arrange the core structure and can push down to the upper end of drill bit body under the effect of stem, when needs take out the stem, will arrange the core structure and push away to the lower extreme, can withdraw from the stem.

Specifically, this arrange core structure is including setting up row core board 5 inside drill bit body 1, and the symmetry sets up the spacing pipe 6 in row core board 5 both sides, the both sides of row core board 5 are provided with the screw that is used for the spacing pipe 6 of installation, the tip of spacing pipe 6 has the screw thread, spacing pipe 6 is arranged core board 5 both sides through its spiro union, spacing pipe 6 is kept away from row core board 5 end and is inserted row core groove 4 spacingly, in order not to influence the drill bit operation, the tip of spacing pipe 6 does not stand out the surface of drill bit body 1, during the use, the body of rod passes row core groove 4 from row core board 5 upside, the stem is discharged inside drill bit body 1 when pressing the body of rod down at row core board 5 top surfaces, at this moment, owing to arrange core board 5 and stem contact, its area is bigger, thereby discharge the stem is easier.

In some embodiments, the limiting pipe 6 is a hollow pipe body, and screw holes on two sides of the battenboard 5 penetrate through the limiting pipe; the structure setting at this moment, the body of rod can be followed the spacing pipe 6 of one side and passed row core board 5 and worn out from the spacing pipe 6 of opposite side to when using, make the body of rod and row core structure group become integrative, when the stem is difficult to withdraw from, can conveniently lift up row core structure principle and keep away from the stem top and pressing to the stem, and then make things convenient for the application of force.

Unless specifically stated otherwise, the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
