Embodiment 1
A kind of powder sampler, as shown in Figure 1-Figure 3, including outer probe tube 1 and interior probe tube 2, interior probe tube 2 are plugged in
In outer probe tube 1.Outer probe tube 1 and interior probe tube 2 be one end closing, one end open hollow cylindrical tube, 1 He of outer probe tube
Multiple sampling grooves 3 are offered in the outside wall surface of interior probe tube 2, sampling groove 3 includes the first sampling groove being set on outer probe tube 1
31 and the first sampling groove 32 on interior probe tube 2, shape, the size of the first sampling groove 31 and the first sampling groove 32 are equal
It is identical, and be arranged at equal intervals along the axis direction of outer probe tube 1 or interior probe tube 2, sampling groove 3 allows powder to enter outer sampling
Inside pipe 1 or interior probe tube 2, sampling groove 3 can be opened or be closed to interior probe tube 2 and outer probe tube 1 when relatively rotating.
Probe tube 2 and outer probe tube 1 close sampling groove 3 in being rotated in advance when sampling, are then taken by interior probe tube 2 and outside
The blind end of sample pipe 1 is inserted into along certain angle in the packaging bag equipped with material, and the interior probe tube 2 of rotation is opened after reaching designated depth
Sampling groove 3 is rotated further by interior probe tube 2 and closes sampling groove 3, then extract sampler out after material is full of interior probe tube 2, and
Taken material is poured into sample container, primary sample is completed.
Since sampling groove 3 is all closed before sampling and after sampling, sampling groove 3 is in the open state when only sampling, in this way
It avoids when toward packaging bag interpolation sampler, material enters in sampler in advance, ensure that same in sampler
The material of height can be corresponding with the material of sustained height in packaging bag, to ensure that the uniformity of material in sampler,
Increase precision when sample survey.
Outer probe tube 1 and interior probe tube 2 are made of stainless steel, and the blind end of the two be it is coniform, it is coniform
Blind end is conducive to probe tube and is inserted into packaging bag in sampling, and the length of interior probe tube 2 is more than the length of outer probe tube 1,
Outer probe tube 1 and interior probe tube 2 easy to disassemble；The open end of interior probe tube 2 is equipped with handle 4, handle 4 relatively in probe tube 2
Axis is vertically arranged, handle 4 so that the taking of sampler, put it is more convenient.
In conjunction with Fig. 4, the end of the open end of outer probe tube 1 is equipped with notch 11, notch 11 on outer probe tube 1 with sampling groove
3 alignment, in probe tube 1 outward in grafting when probe tube 2, notch 11 is conducive to the grafting of interior probe tube 2.
Fig. 2 and Fig. 3 are reviewed, as a preferred mode, the groove width of the first sampling groove 31 or the first sampling groove 32 is small
In outer probe tube 1 or the diameter of interior probe tube 2, it can ensure that the area of the wall surface for not opening up sampling groove 3 of probe tube is more than and take
The notch of sample slot 3 can completely enclose sampling when to ensure that probe tube 2 or outer probe tube 1 close sampling groove 3 in rotation
Slot 3.
Embodiment 2
In conjunction with Fig. 5, difference lies in the differences of outer probe tube 1 with embodiment 1 for embodiment 2.
The open end of the present embodiment China and foreign countries probe tube 1 is equipped with end cap 5, and end cap 5 includes the open end screw thread with outer probe tube 1
The integrally formed hand in lid portion 51 and 51 both sides of lid portion of connection holds portion 52, and hand holds the axis of the outer probe tube 1 relatively of portion 52
It is vertically arranged.End cap 5 is not only convenient to rotate outer probe tube 1, but also when taking out the material in probe tube, directly backs out end
Lid 5, it is easy to use.
In conjunction with Fig. 6, as another preferred mode, the tube wall of the open end of outer probe tube 1 is equipped with first identifier line
6, the position on 2 tube wall of interior probe tube close to the open end of outer probe tube 1 is equipped with second identifier line 7, first identifier line 6 and second
Tag line 7 is arranged along the axis of outer probe tube 1 or interior probe tube 2, and first identifier line 6 and second identifier line 7 are protrusion
Fin；When first identifier line 6 is aligned with second identifier line 7, the first sampling groove 31 is aligned with the first sampling groove 32.
The height of the lower end of second identifier line 7 can prevent interior higher than the height where the end of the open end of interior probe tube 2
When probe tube 2 is mutually rotated with outer probe tube 1, second identifier line 7 and the open end of interior probe tube 2 interfere.
When sampler is inserted into packaging bag, it is difficult to judge whether the first sampling groove 31 is aligned with the first sampling groove 32.
Therefore first identifier line 6 contributes to user preferably to judge the first sampling groove 31 and the first sampling groove 32 with second identifier line 7
Whether it is aligned, to ensure that the first sampling groove 31 is fully aligned with the first sampling groove 32 so that the use of sampler is more square
Just.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
As long as all being protected by Patent Law in the right of the utility model.
