[0002] With the continuous development of science and technology, sampling inspection, also known as sampling inspection, is a statistical method and theory that randomly selects a small number of products (samples) from a batch of products for inspection to determine whether the batch of products is qualified. There are three methods of sampling inspection: simple random sampling, systematic sampling, and stratified sampling.

[0003] An existing multifunctional grain sampling device can refer to the Chinese utility model patent with authorization announcement number CN219416857U, which discloses a multifunctional grain sampling device, "including a negative pressure adsorption structure, the negative pressure adsorption structure and the material taking pipe are connected by a material guide pipe, the inner wall of the lower end of the material taking pipe is connected with a middle pipe by a thread, the inner wall of the lower end of the middle pipe is connected with a sampling head by a thread, the outer wall of the negative pressure adsorption structure is clamped with a support assembly, the bottom end of the negative pressure adsorption structure is equipped with a support assembly, and the bottom of the support assembly is equipped with a screening assembly. The head of the replacement rod is designed to be replaceable, so that the entire sampling device is suitable for various scenarios, and the middle pipe in the middle of the sampling rod can adjust the length of the sampling rod to facilitate the sampling of deep grain, and the bottom of the sampling negative pressure adsorption structure is equipped with a screening device, so that the sampling device can directly screen the grains when sampling various grain mixtures for easy inspection by sampling personnel. When there are too many impurities in the sampled grains, the impurities can also be screened to ensure the cleanliness of the sampled samples."

[0004] When the above device is in use, it is designed to be replaceable by replacing the head of the rod, so that the entire sampling device is suitable for various scenarios, and the middle tube in the middle of the sampling rod can adjust the length of the sampling rod to facilitate the sampling of deep grain. The above device is not convenient for sampling grains at different depths at the same time, so multiple samplings are required, which increases the time for sampling. For this reason, we propose a rapid grain sampling device. Utility Model Content

The first feeding port 2 is opened to facilitate the entry of grain into the inner wall of the feeding tube 3. Since the outer wall of the feeding tube 3 is provided with a second feeding port 4, grain sampled from different positions can be stored, and then the fixed baffle 5 can be used to place the stored grain. At the same time, the first discharge port 6 is opened to allow the connecting block 10 to be rotated to adjust the position of the connecting baffle 8, thereby preventing grain from leaking out.

[0022] A limiting groove 11 is provided at the top of the insert tube 1, a limiting block 12 is inserted into the inner wall of the limiting groove 11, and the limiting block 12 is fixedly connected to the outer wall of the material taking tube 3. The limiting groove 11 makes it convenient to use the limiting block 12 to limit the position of the material taking tube 3 so that the material taking tube 3 can only be raised and lowered.

[0023] A second discharge port 13 is formed on the outer wall of the insert tube 1, and a sealing block 14 is threadedly connected to the inner wall of the second discharge port 13. When the sealing block 14 is rotated out, a connecting pipe 15 is threadedly connected to the inner wall of the second discharge port 13, a rotating tube 16 is threadedly connected to the outer wall of the connecting tube 15, and a material guide tube 17 is threadedly connected to the inner wall of the rotating tube 16. The sealing block 14 can be used to seal the material taking pipe 3 at the opened second discharge port 13, thereby preventing leakage of grain when the grain is sampled.

[0024] The other end of the material guide pipe 17 is fixedly connected to the outer wall of the negative pressure adsorption device 18, the bottom of the negative pressure adsorption device 18 is fixedly connected to the separation device 19, and the inner wall of the separation device 19 is fixedly connected to the partition plate 20.

[0025] An electric telescopic rod 21 is fixedly connected to the side of the separation device 19, and a push plate 22 is fixedly connected to the output end and the outer wall of the electric telescopic rod 21. A discharge trough 23 is provided on the front of the separation device 19, and a receiving plate 24 is inserted into the inner wall of the discharge trough 23.

[0026] There are three partition plates 20, which are evenly fixedly connected to the inner wall of the separation device 19, and the connection heights of the three partition plates 20 are different. Separation openings are opened on the tops of the three partition plates 20, and the diameters of the separation openings opened by the three partition plates 20 are different. Due to the number of partition plates 20, different grains and impurities can be screened, and the separation openings opened by the higher partition plates 20 welded to the inner wall of the separation device 19 have a smaller diameter, so that the impurities can be screened out first, so as to facilitate subsequent random inspections.

[0027] Working principle: during operation, when sampling grain, through the coordinated use of the insert tube 1 and the first material taking port 2, after the insert tube 1 is inserted into the grain, the material taking pipe 3 is pulled, so that grains of different depths enter the top of the fixed baffle 5 through the second material taking port 4, so as to facilitate stratified sampling. After sampling, the material taking pipe 3 is pressed downwards, so that the insert tube 1 can be easily pulled out, and at the same time, the first discharge port 6 and the second discharge port 13 are opened, and then the connecting block 10 can be rotated to drive the connecting baffle 8 to move, so that the connecting pipe 15 is threadedly connected to the inner wall of the first discharge port 6 and the second discharge port 13, so as to facilitate sampling at different depths. The next step of random inspection of grain is to use the negative pressure adsorption device 18 and the guide tube 17 in coordination, and use the rotating tube 16 and the connecting tube 15 to facilitate the extraction of grain on the inner wall of the feeding tube 3, and then to draw the extracted grain to the inner wall of the separation device 19, and to screen the grain through the connected partition plate 20. After screening the grain, the electric telescopic rod 21 and the push plate 22 can be used to push the screened grain to the top of the next partition plate 20, and the connected receiving plate 24 can be used to allow the screened grain to enter the inner wall of the receiving plate 24, so as to facilitate distinction, and at the same time, the connecting partition plate 25 is used to separate them.
