[0001] The utility model relates to the technical field of food detection, in particular to a sampling device for detecting powdery food. Background Art

[0002] Food safety detection is to detect harmful substances in food according to national standards, mainly the detection of some harmful and toxic indicators, such as heavy metals, aflatoxins, etc. An important aspect of food science and engineering is to introduce and apply chemical engineering unit operations and develop them into food engineering unit operations, so as to promote the development of the food industry towards large-scale, continuous and automated directions.

[0003] For example, the Chinese patent with the publication number CN219532529U discloses a sampling device for food detection, which includes a control handle. The lower end of the control handle is fixedly connected with a second electric push rod. The output end of the lower part of the second electric push rod is provided with a fixed seat. The lower end of the fixed seat is provided with a ramp seat through a support rod. The outer side of the fixed seat is fixedly installed with a rotating frame arranged at intervals. A connecting rod is hinged on the rotating frame. The lower end of the connecting rod is hinged with a clamping rod. The lower side of the ramp seat is fixedly installed with a first electric push rod arranged at intervals. The output end of the first electric push rod is rotatably connected with the clamping rod. One end of the inner side of the clamping rod is fixedly installed with a wrapping shell. During the use of the utility model, for powdery food with large-volume packaging, during the sampling process, it can avoid the contamination of the sampling sample, ensure the objective accuracy of subsequent detection, and avoid the phenomenon of pouring the powdery food with large-volume packaging first and then sampling the poured part, thus avoiding the existence of waste phenomenon and being beneficial to popularization and use.

[0004] After using this sampling device for food detection, it is found that although this sampling device for food detection can perform sampling, the resistance received by the clamping rod during clamping is relatively large, and it will receive a large resistance from the powdery food during sampling, making it inconvenient to use. Content of the Utility Model

[0011] Preferably, the inner wall of the lower end of the material taking cylinder is an arc surface, and the outer wall of the rotating piece is an arc surface.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Please refer to Figures 1-6 , the present utility model provides a technical solution: a powder food detection sampler, including an outer cylinder 1. When in use, hold the outside of the outer cylinder 1 by hand. A material taking cylinder 2 is slidably connected inside the outer cylinder 1. The material taking cylinder 2 moves up and down and drills into the powder food. A drill bit 201 is fixedly connected to the bottom of the material taking cylinder 2. The drill bit 201 can drill into the powder food with very little resistance. A first rotating shaft 401 is rotatably connected to the middle of the outer cylinder 1. The first rotating shaft 401 penetrates through the upper part of the outer cylinder 1. A telescopic sleeve 404 is fixedly connected to the bottom of the first rotating shaft 401. When the first rotating shaft 401 rotates, the telescopic sleeve 404 can be rotated. A spline shaft 405 is slidably connected inside the telescopic sleeve 404. When the telescopic sleeve 404 rotates, the spline shaft 405 can be rotated. The spline shaft 405 can move up and down inside the telescopic sleeve 404 without detachment to transmit the rotational force. A second rotating shaft 406 is fixedly connected to the bottom of the spline shaft 405. When the spline shaft 405 rotates, the second rotating shaft 406 can be rotated. A rotating piece 407 is fixedly connected to the bottom of the second rotating shaft 406. When the second rotating shaft 406 rotates, the rotating piece 407 can be rotated. The rotating piece 407 contacts the material taking cylinder 2. There are openings on the outside of the material taking cylinder 2. During the downward movement of the material taking cylinder 2, the rotating piece 407 blocks the openings, and the powder food will not enter the inside of the material taking cylinder 2. After the lower part of the material taking cylinder 2 reaches the designated position, the rotating piece 407 rotates 90 degrees, and the powder food enters the inside of the material taking cylinder 2 and stays above the drill bit 201. Reset the rotating piece 407, and then move the material taking cylinder 2 upward. During the upward movement, the internal powder food will not overflow, and the external powder food will not enter the inside. An electric motor 3 is fixedly installed at the top of the inner wall of the outer cylinder 1. A screw 301 is fixedly installed on the output shaft of the electric motor 3. The screw 301 is threadedly connected to the material taking cylinder 2. When the electric motor 3 rotates, the screw 301 rotates, and the material taking cylinder 2 descends. When the electric motor 3 rotates in the reverse direction, the material taking cylinder 2 ascends.

[0023] Among them, a rotating handle 4 is fixedly connected to the top of the first rotating shaft 401. By rotating the rotating handle 4, the first rotating shaft 401 can be rotated, which is more convenient to use and can only be rotated by 90 degrees.

[0024] Among them, a limiting groove 403 is opened at the top of the outer cylinder 1. A convex block 402 is fixedly connected to the outer wall of the first rotating shaft 401. The convex block 402 is matched with the limiting groove 403. The overall shape of the limiting groove 403 is a quarter circle. The convex block 402 moves inside the limiting groove 403 and can only be rotated by 90 degrees, so that the material taking cylinder 2 will not be mixed with the powdery food at different depths when collecting powdery food.

[0025] Among them, handles 101 are fixedly connected to both sides of the outer cylinder 1, making it more convenient to hold the outer cylinder 1.

[0026] Among them, the first rotating shaft 401 and the second rotating shaft 406 are on the same central axis. When the first rotating shaft 401 rotates, the telescopic sleeve 404 rotates, the spline shaft 405 rotates, and the second rotating shaft 406 rotates.

[0027] Among them, the inner wall of the lower end of the material taking cylinder 2 is an arc surface, and the outer wall of the rotating piece 407 is an arc surface. The material taking cylinder 2 is matched with the rotating piece 407. The rotating piece 407 is in close contact with the material taking cylinder 2, but the material taking cylinder 2 does not affect the rotation of the rotating piece 407.

[0028] Working principle: When in use, hold the outside of the outer cylinder 1 by hand. The motor 3 rotates, the screw 301 rotates, and the material taking cylinder 2 descends. After the lower part of the material taking cylinder 2 reaches the designated position, rotate the rotating handle 4. The first rotating shaft 401 rotates, the telescopic sleeve 404 rotates, the spline shaft 405 rotates, the second rotating shaft 406 rotates, and the rotating piece 407 rotates by 90 degrees. The powdery food enters the inside of the material taking cylinder 2. After sampling is completed, reset the rotating piece 407. The motor 3 rotates in the reverse direction to move the material taking cylinder 2 upward. During the upward movement, the powdery food inside will not overflow, and the powdery food outside will not enter the inside. After taking it out, rotate the rotating piece 407 again to take out the powdery food.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes and modifications can be made to these embodiments without departing from the principle of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
