[0032] Refer to Figures 1 to 4 The present invention provides a powder sample sampler 100.

[0033] In the embodiments of the present invention, the powder sample sampler 100 includes:

[0034] A first sampling housing 10 and a second sampling housing 20, the first sampling housing 10 is connected to the second sampling housing 20 and has a feeding position and a sampling position relative to the second sampling housing 20;

[0035] In the feeding position, the first sampling housing 10 and the second sampling housing 20 enclose to form a plurality of sample storage grooves 100a and a feeding channel 100b communicating with the plurality of sample storage grooves 100a. The central axis of the sample storage groove 100a is perpendicular to the central axis of the feeding channel 100b, and the lower end of the feeding channel 100b is open;

[0036] In the sampling position, the second sampling housing 20 opens the plurality of sample storage grooves 100a and the feeding channel 100b;

[0037] A plurality of pushing members 30 are connected to the first sampling housing 10. One pushing member 30 corresponds to one storage sample groove 100a. The pushing member 30 can move relative to the first sampling housing 10 to push the powder sample into the feeding channel 100b.

[0038] Specifically, the first sampling housing 10 and the second sampling housing 20 can be made of transparent plastic material, which is convenient for production and molding, and also convenient for inspectors to observe the samples therein. A connecting shaft hole 10b is formed at the edge of the first sampling housing 10, and a rotating shaft 21 is correspondingly formed on the second sampling housing 20. The rotating shaft 21 is rotatably sleeved in the connecting shaft hole 10b to rotatably connect the first sampling housing 10 and the second sampling housing 20.

[0039] At the feeding position, the first sampling housing 10 and the second sampling housing 20 are mutually attached to jointly enclose a plurality of storage sample grooves 100a and a feeding channel 100b. At the sampling position, the second sampling housing 20 can rotate relative to the first sampling housing 10 to open the plurality of storage sample grooves 100a and the feeding channel 100b, and put the powder sample therein. That is, a plurality of storage sample grooves 100a and the feeding channel 100b are partially located in the first sampling housing 10 and partially located in the second sampling housing 20.

[0040] In actual use, the first sampling housing 10 and the second sampling housing 20 can be placed at the sampling position, and the taken powder sample is poured onto the surfaces of the first sampling housing 10 and the second sampling housing 20 at one time. Then, the first sampling housing 10 and the second sampling housing 20 are adjusted to the feeding position. At this time, the powder sample is placed in a plurality of storage sample grooves 100a and the feeding channel 100b. The powder sample is placed vertically. The powder sample in the feeding channel 100b is removed under the action of gravity, and the remaining powder sample is placed in the storage sample grooves 100a. When detecting the powder sample, only need to push the pushing member 30 in the horizontal direction, and the powder sample in the storage sample groove 100a can be pushed into the feeding channel 100b in the horizontal direction. Under the action of gravity, the powder sample falls onto the detection device, and so on. In this application, by setting a plurality of storage sample grooves 100a and a plurality of pushing members 30, the sample can be fed in multiple times after collecting the powder sample once. At the same time, by separately setting the first sampling housing 10 and the second sampling housing 20, it is more convenient to put the powder items into the storage sample grooves 100a in the open state, thus greatly improving the sampling and detection efficiency.

[0041] Please refer to again Figure 2 and Figure 3, in one embodiment, the pusher member 30 includes a connecting rod 31 and a pusher plate 32 connected to the end of the connecting rod 31. The cross-section of the pusher plate 32 is adapted to the size and shape of the cross-section of the sample storage groove 100a. The first sampling housing 10 is provided with a connection hole 10a communicating with the sample storage groove 100a. The connecting rod 31 extends into the sample storage groove 100a through the connection hole 10a, and the pusher plate 32 is accommodated in the sample storage groove 100a. Under the action of an external force, the pusher plate pushes the powder sample into the delivery channel 100b.

[0042] Further, the pusher member 30 includes a spring 33, and the spring 33 is elastically connected to the first sampling housing 10 and the pusher plate 32. In the natural state, the spring 33 provides a pulling force to pull the pusher plate 32 toward the side of the connection hole 10a, that is, away from the delivery channel 100b. When delivering the powder sample, the user pushes the connecting rod 31, thereby overcoming the pulling force of the spring 33 and pushing the pusher plate 32 toward the delivery channel 100b. After delivering the powder sampler, under the action of the spring 33, the pusher plate 32 returns to the initial position. In this way, the use of the powder sample sampler 100 is more convenient.

[0043] Furthermore, the pusher member 30 further includes an assisting handle 34, and the assisting handle 34 is integrally formed and connected to the end of the connecting rod 31 away from the pusher plate 32. By providing the assisting handle 34, it is convenient for the user to operate the pusher member 30.

[0044] Please refer to again Figure 3 and Figure 4 , in the present application, the first sampling housing 10 is further provided with an arc-shaped limiting hole 10c, and the second sampling housing 20 is provided with a limiting protrusion 22. After the first sampling housing 10 and the second sampling housing 20 are installed, the limiting protrusion 22 is accommodated in the arc-shaped limiting hole 10c. In the present application, when the first sampling housing 10 and the second sampling housing 20 are in the sampling position, the two are arranged in parallel. Therefore, in order to prevent the second sampling housing 20 from rotating excessively, by reasonably setting the radian of the arc-shaped limiting hole 10c, the limiting protrusion 22 abuts against the hole side wall of the arc-shaped limiting hole 10c, so as to further facilitate the user to take samples.

[0045] In one embodiment of the present application, in the delivery position, the first sampling housing 10 is detachably connected to the second sampling housing 20. Such a setting ensures that on the one hand, when delivering the sample, the two will not rotate relative to each other and spill the powder sample, and on the other hand, it is also convenient for the user to open the sample storage groove 100a and the delivery channel 100b.

[0046] Specifically, the first sampling housing 10 is provided with a first magnetic member 11, and the second sampling housing 20 is provided with a second magnetic member 23. Among them, one of the first magnetic member 11 and the second magnetic member 23 is a permanent magnet, and the other is a metal that can be magnetically attracted by the permanent magnet, such as iron, steel, etc., or both are permanent magnets. The first magnetic member 11 and the second magnetic member 23 are respectively connected to the first sampling housing 10 and the second sampling housing 20 through glue or hot melting processes. Through the magnetic attraction of the two, it is more labor-saving for the user to open the sample storage tank 100a and the feeding channel 100b. Of course, the first sampling housing 10 and the second sampling housing 20 can also be connected through a snap structure, which is not limited herein.

[0047] In this embodiment, the lower part of the feeding channel 100b is tapered, so that when the powder sample is fed, its flow rate is more uniform and the placement position of the sample is easier to control.

[0048] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
