Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model is carried out it is clear,
It is fully described by.Following examples are only used for clearly illustrating the technical solution of the utility model, and can not be limited with this
Make protection domain of the present utility model.
As shown in figure 1, being a kind of rock chisel bit, including drill body, drill body includes sampling portion 1, sampling portion 1
It is connected with hand-held water drilling by connecting portion 2；Sampling portion 1 includes cylindrical sampling sleeve 10, and sampling sleeve 10 is near rock
The bottom border of stone is evenly equipped with several and bores pawl 100；As shown in figure 3, connecting portion 2 includes sample holding part 20 and sample holding
The drilling rod 22 that portion 20 is connected away from the connected locating piece 21 in the top of rock and positioned at the opposite side of locating piece 21 with hand-held water drilling；
Wherein, sample holding part 20 is removably plugged in sampling sleeve 10, and sample holding part 20 is matched somebody with somebody with the sampling inwall of sleeve 10
Close the face of cylinder formed for sampling.
Specifically, with reference to shown in Fig. 2, sampling sleeve 10 includes first branch 101 and the second branch 102 of one；First
The inner surface of branch 101 is smooth；Second branch 102 caves inward and along the axle of sleeve compared to the inner surface of the first branch 101
To offering several grooves 103, and the second branch 102 is provided near the bottom of rock and is put down with the first branch 101 inner surface
Neat positive stop lug boss 104, the top of groove 103 is open, bottom and the integrally connected of positive stop lug boss 104.Also, the first branch 101
With the second branch 102 with the median plane of sleeve as separating surface.
As shown in figure 3, sample holding part 20 includes the support shell 201 of arc, it is convexly equipped with and groove on the support outer surface of shell 201
The fin 203 of the equivalent amount of 103 adaptations；As shown in figure 4, the branch 102 of support shell 201 and second is by groove 103 and fin 203
Form corresponding plug to coordinate, and hold in the palm the radial thickness at the arbitrary place of shell 201 and the radial thickness sum of the corresponding position of the second branch 102
Equal to the radial thickness of the first branch 101, so as to after insertion sampling sleeve 10 of shell 201 are held in the palm, hold in the palm the inner surface and first of shell 201
Branch 101 is concordant, and asks the inner surface of shell 201 and the inner surface of the first branch 101 to cooperatively form the face of cylinder for sampling.
Support shell 201 length vertically is the height of positive stop lug boss 104 and sampling sleeve 10 between the top of drilling rod 22
Degree is poor.
Wherein, groove 103 is set to uniform 3 along the second branch 102；Accordingly, fin 203 is set to hold in the palm the appearance of shell 201
Face is evenly spaced 3；Locating piece 21 is cylindrical, and the diameter of locating piece 21 is less than the external diameter for sampling sleeve.
Structural principle of the present utility model is further detailed below in conjunction with the accompanying drawings.
As shown in figure 4, this utility model when hold in the palm shell 201 insertion sampling sleeve 10 after, hold in the palm shell 201 inner surface and first point
Portion 101 is concordant, and asks the inner surface of shell 201 and the inner surface of the first branch 101 to cooperatively form the face of cylinder for sampling；Together
When, the length for holding in the palm shell 201 is top and the difference in height on the top of positive stop lug boss 104 for sampling sleeve, after being sampled, uses weight
Beaing the top of sampling sleeve 10 makes it to depart from connecting portion 2 be obtained cylinder standard specimen.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, some improvement and deformation can also be made, these change
Enter and deform also to should be regarded as protection domain of the present utility model.
