Description
Technical Field
The utility model relates to a check out test set field specifically is a check out test set for food aflatoxin content.
Background
Aflatoxin is one of the most recognized carcinogenic substances in the chemical carcinogens found at present, and exists in moldy plant foods, such as peanuts, corns and the like, but is also polluted if animals eat feeds polluted by aflatoxin.
In order to detect whether the meat product contains aflatoxin, detection methods such as thin-layer chromatography and the like are generally adopted for detection, extraction equipment is used for extracting a sample in the detection process, and then the sample is subjected to steps such as elution, concentration, thin-layer separation and the like, and then detection is carried out.
The extraction equipment adopted in the detection process is generally used for scraping a part of the meat products from the outer side, and although the operation is simple, the sampling is difficult to carry out when the meat products are stored in large quantities.
SUMMERY OF THE UTILITY MODEL
The utility model aims at above problem, provide a check out test set for food aflatoxin content, can sample the nexine of meat product fast.
In order to realize the above purpose, the utility model adopts the technical scheme that: the sampling device comprises a sampling cylinder with a hollow inner part, wherein the front end of the sampling cylinder is conical, a sampling window is arranged on the side wall of the sampling cylinder, a support is arranged in the sampling cylinder, a sampling knife is arranged on the support along the axial direction of the sampling cylinder, the cutting edge of the sampling knife is arranged along the radial direction of the sampling cylinder, and the cutting edge of the sampling knife is rotated from one end to the other end of the sampling window so as to perform sampling after the sampling cylinder is inserted into meat; in order to drive the sampling cutter to rotate, the lower end of the support is provided with a rotating shaft, and one end of the rotating shaft extends out of the rear end of the sampling cylinder.
Further, in order to store samples and facilitate cleaning, the sampling cylinder is formed by splicing a front part, a middle part and a rear part which are sequentially arranged; the sampler barrel is inboard to be provided with the baffle along its radial, set up the arc hole between baffle and the sampler barrel inner wall, the sample sword passes the arc hole and extends to the sampler barrel front end.
Furthermore, in order to reduce the probability of sample pollution, the arc length of the sampling knife is greater than that of the sampling window, and the height of the sampling knife is greater than that of the sampling window, so that the sampling window can be completely closed by the side wall of the sampling knife.
Further, to facilitate assembling the front portion, the middle portion and the rear portion together, the front portion and the rear portion are respectively screw-coupled at front and rear ends of the middle portion.
Further, for preserving the sample, still include upper cover and hou gai, upper cover and hou gai detachable set up both ends around the middle part.
The utility model has the advantages that: the sampling cylinder front end is the toper to conveniently insert the sampling cylinder in the meat, then rotate the sampling sword through the rotation axis, so that the blade of sampling sword moves from sampling window one side to the opposite side, thereby scrapes a small amount of sample.
1. The sampling tube is formed by splicing the front part, the middle part and the rear part of the sampling tube in a threaded manner, a nested manner and the like, and is convenient to clean and store.
2. The sampling cutter can close the sampling window completely, so that a sample positioned in the middle of the sampling cylinder is prevented from being polluted as much as possible, and the detection accuracy is improved.
3. After the sampling is finished, the middle part is taken down, and then the upper cover and the rear cover are arranged at the front end and the rear end of the middle part, so that the samples are convenient to transport.

Detailed Description
In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.
Example 1: as shown in fig. 1-2, the specific structure of this embodiment is: the sampling device comprises a hollow sampling cylinder 1, wherein the front end of the sampling cylinder 1 is conical so as to be conveniently inserted into meat products, a sampling window 2 is formed in the side wall of the sampling cylinder 1, a support 5 is arranged in the sampling cylinder 1, a sampling knife 6 is arranged at the edge of the upper end of the support 5, the sampling knife 6 is axially arranged along the sampling cylinder 1, the radian of the sampling knife 6 is matched with the inner wall of the sampling cylinder 1, and the sampling knife 6 is tightly attached to the inner wall of the sampling cylinder 1; the support 5 lower extreme is provided with rotation axis 7, the bearing that rotation axis 7 one end passed sampler barrel 1 rear end stretches out sampler barrel 1.
During the sample, insert meat with sampling window 2 mode up with sampling cylinder 1 front end, the meat is not got into to rotation axis 7 rear end, and the meat that waits to detect this moment has some to enter into sampling cylinder 1 from sampling window 2 in, then rotates rotation axis 7 to cut the meat, thereby obtain the sample.
Example 2: as shown in fig. 1-3, the other structure of the present embodiment is the same as that of embodiment 1, but in the present embodiment, the sampling cylinder 1 is formed by splicing a front part 8, a middle part 9 and a rear part 10, wherein the front part 8 and the rear part 10 are installed at the front end and the rear end of the middle part 9 in a threaded manner, the front end of the front part 8 is conical, the rotating shaft 7 is installed on the rear part 10, and the sampling window 2 is arranged on the side wall of the middle part 9; a partition plate 3 is arranged on the inner side of the sampling cylinder 1 along the radial direction of the sampling cylinder, part of the partition plate 3 is connected with the inner wall of the middle part 9, an arc-shaped hole 4 is formed between the partition plate 3 and the inner wall of the sampling cylinder 1, the arc-shaped hole 4 is a major arc, the sampling knife 6 penetrates through the arc-shaped hole 4 and extends to the front end of the sampling cylinder 1, and meat cut by the sampling knife 6 falls on the partition plate 3; the arc length of the sampling knife 6 is larger than that of the sampling window 2, and the height of the sampling knife 6 is larger than that of the sampling window 2.
The procedure for sampling was the same as in example 1, except that after the sampling cylinder 1 was removed from the meat to be tested, the front part 8 and the rear part 10 were turned to remove the middle part 9, and then the upper cover 11 and the rear cover 12 were attached to the front and rear ends of the middle part 9, the rear cover 12 having a height such that the sampling window 2 was closed.
