The saddle with inclined-plane is distributed with, the inclined-plane is equipped with sliding slot, is equipped with sliding block in sliding slot, sliding block is matched with interior bar, and inclined-plane
Be oriented and prevent interior bar with respect to outer bar to the direction of downslide；It further include pushing out ring, sliding block and interior bar is isolated in the pushing out ring.
One kind above-mentioned is filled in material compactness detection sampler, and the interior bar is equipped with axial scale.
One kind above-mentioned is filled in material compactness detection sampler, and the surface that the sliding block is contacted with interior bar is equipped with rubber
Layer.
One kind above-mentioned is filled in material compactness detection sampler, and the outer bar is equipped with outer handle, in the interior bar
Equipped with Internal handle, rubber sleeve is all provided on outer handle and Internal handle.
Compared with prior art, the utility model controls the shape tested pits by outer drill bit, recycles interior drill bit to drill through and fills out
Material, the volume tested pits can be calculated according to the depth of interior drill bit.What the utility model was dug out as a result, tests pits as the cylinder of rule
Body, calculating volume is very convenient, the step of filling sand can be saved, to greatly simplify measuring process.The utility model sampling
Operation it is not only quick but also laborsaving, thus the water-cut variation of sample will not be too big, guarantee the levels of precision of measurement result.Not only
In this way, the utility model can lock interior bar by the structure of bearing, saddle and sliding block, allow to rotate still relative to outer bar
It will not continue to dig in the axial direction deeply, after rotating several circles in the case where interior drill bit is not fed axially, testing pits for digging out can guarantee
It is a cylindrical body, guarantees the levels of precision of measurement result.
Further, scale is arranged in the utility model in interior bar, facilitates reading, improves detection speed.
To sum up, the utility model has auxiliaring effect good, and sampling efficiency is high, and detection accuracy can be improved and simplify detection step
Rapid feature.

Specific embodiment
Below with reference to embodiment, the utility model is described in further detail, but be not intended as to the utility model limit according to
According to.
Embodiment: one kind filling material compactness and detects sampler, the outer drill bit 10 including cylindrical shape, under outer drill bit 10
Along cutter head is equipped with, the upper end of outer drill bit 10 is connected with hollow outer bar 11；Interior bar 21 is equipped in the outer bar 11, under interior bar 21
End is equipped with spiral helicine interior drill bit 20, and interior drill bit 20 is arranged in outer drill bit 10；Bearing 30, bearing are additionally provided in the outer bar 11
30 inner ring annular spread has the saddle 31 with inclined-plane 32, and the inclined-plane 32 is equipped with sliding slot, is equipped with sliding block 33, sliding block in sliding slot
33 match with interior bar 21, and the surface that the sliding block 33 is contacted with interior bar 21 is equipped with rubber layer, and the sliding block 33 connects with interior bar 21
The surface of touching is equipped with rubber layer and being oriented for inclined-plane 32 prevents the opposite outer bar 11 of interior bar 21 to the direction of downslide；It further include pushing out ring
34, sliding block 33 and interior bar 21 is isolated in the pushing out ring 34.The outer diameter of interior drill bit 20 and the internal diameter of outer drill bit 10 are equal.
