[0018] Figure 1 It is a schematic diagram of the overall structure of the solid powder sampling device of the utility model. DETAILED DESCRIPTION

[0019] The solid powder sampling device of the present invention will be described in more detail below in conjunction with a schematic diagram, wherein a preferred embodiment of the present invention is shown, and it should be understood that those skilled in the art can modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the present invention.

[0020] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0021] like Figure 1 As shown, an embodiment of the utility model provides a solid powder sampling device, comprising a drilling tube 1, a sampling tube 2 and a sampling handle 3.

[0022] Specifically, the drilling pipe 1 is provided with a plurality of feed ports 4 along its length direction, and the drilling pipe 1 is provided with a sealing sheet 5 near the drilling end.

[0023] The sampling tube 2 is movably arranged inside the drilling tube 1 , and the sampling tube 2 can rotate and linearly slide inside the drilling tube 1 . A plurality of sampling ports 6 matching the feed port 4 are arranged on the side wall of the sampling tube 2 .

[0024] The sampling handle 3 is fixedly disposed at one end of the sampling tube 2 away from the drilling tube 1 , and the sampling handle 3 is exposed outside the drilling tube 1 .

[0025] In this embodiment, when it is necessary to sample the solid powder, the drill tube 1 is inserted into the solid powder, and then the sampling tube 2 is rotated by the sampling handle 3 so that the sampling port 6 is aligned with the feed port 4 one by one, and then the sampling handle 3 is rotated back and forth around the feed port 4 until the powder of different depths passes through the feed port 4 and the sampling port 6 in turn and enters the sampling tube 2, and finally the sampling handle 3 is rotated to seal the sampling port 6, and the sampler is taken out to remove the powder.

[0026] In order to facilitate the insertion of the drill tube 1 into the fixed powder, a drill handle 7 is provided at one end of the drill tube 1 close to the sampling handle 3 .

[0027] Furthermore, one end of the drilling tube 1 away from the drilling handle 7 is arranged to be planar, and the sealing sheet 5 seals the planar opening.

[0028] In a specific embodiment, the feed ports 4 are distributed in a straight line, and the spacing between two adjacent feed ports 4 is equal. The feed ports 4 are evenly and linearly distributed, and when the sampling port 6 is aligned with the feed ports 4 one by one, solid powders of different depths can be fed into the sampling tube 2 by rotating the sampling tube 2.

[0029] In order to prevent solid powder from entering the gap between the sampling tube 2 and the drilling tube 1 , the sampling tube 2 is fitted and in sliding contact with the inner wall of the drilling tube 1 .

[0030] Furthermore, the sampling port 6 is configured to be circular, and the diameter of the sampling port 6 is the same as the diameter of the feed port 4 .

[0031] When sampling solid powders at different depths, in order to facilitate the rapid docking of the sampling port 6 with the feed port 4, the sampling tube 2 is rotated and adjusted, specifically:

[0032] The sampling tube 2 and the drilling tube 1 are both provided with rotation marking lines 8 on their outer side walls, and when the two rotation marking lines 8 are connected, the sampling port 6 and the feed port 4 are linearly distributed along the length direction of the drilling tube and overlap and communicate with each other.

[0033] When the sampling port 6 and the feed port 4 are on the same circumferential surface, the sampling tube 2 is rotated back and forth around the feed port 4, so that the sampling port 6 is continuously and intermittently connected with the feed port 4, and the solid powder corresponding to different depths can pass through the feed port 4 and the sampling port 6 and enter the sampling tube 2. Since the whole sampling process is constantly rotating, the samples of different depths can be fully mixed, so that the subsequent sampling test results are more representative.

[0034] Compared with the prior art, the utility model has at least the following beneficial effects:

[0035] The utility model inserts a drill tube into solid powder, and rotates the sampling tube so that the sampling port corresponds to the feed port in the drill tube one by one, thereby realizing mixed sampling operation of solid powder at different depths, greatly improving the sampling efficiency of solid powder, and fully mixing samples at different depths, making the sample sampling and detection more uniform and representative, and having the characteristics of simple structure and convenient operation.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
