Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling, and more specifically to a meat homogenization sampling device. Background Technology
[0002] With increasing emphasis on food safety, especially given the frequent problems with meat products in recent years—common issues such as the illegal use of veterinary drugs and clenbuterol in livestock and poultry farming, and the entry of diseased meat into the market evading quarantine—meat products constitute a significant proportion of the sampling and testing projects determined by the State Administration for Market Regulation and local authorities. Strengthening the supervision and testing of meat is a crucial task for food safety supervision and management agencies and the distribution channels.
[0003] Traditional methods for microbial testing of meat samples require personnel to carry a microbial sampling kit and strictly adhere to aseptic techniques. Samples are then homogenized using sterile scissors and a mortar. A common method used by lab instructors is to use a sterile homogenizer. The original, sterile sample is cut into approximately 10×10mm pieces and placed in a homogenization bag with a liquid or solvent. The instrument's hammer plate repeatedly strikes the sample homogenization bag, generating pressure, causing vibration, accelerating mixing, and achieving a uniform distribution of microbial components in the solution.
[0004] Meanwhile, Chinese patent number 201810429459.1, entitled "A Sterile Sampling Device for Meat Product Testing Samples," discloses a technical solution that solves the technical problem of manual sampling, but has the following defects in actual use: Existing patents use a pointed sampling head, which results in uneven samples when sampling meat tissue because the sharp sampling head will directly pierce through it. Therefore, it is not easy to distinguish between the skin, fat and muscle tissue when sampling. When sampling meat with a hard skin, existing sampling drills are difficult to break through the skin, such as some fish. Summary of the Invention

Detailed Implementation
[0016] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.
[0017] In the description of this utility model, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the terms according to the specific circumstances.
[0018] like Figure 1 As shown, the meat homogenization sampling device of this utility model includes: a sampling component 1, a connecting component 2 and a driving component 3. The front end of the driving component 3 is connected to the sampling component 1 through the driving component 3, and the driving component 3 drives the sampling component 1 to rotate and sample.
[0019] like Figure 2 As shown, the sampling assembly 1 includes: a sampling sleeve 11, a clamping nut 12, and a sampling drill bit 13. The rear end of the sampling drill bit 13 is connected to the drive assembly 3 through the connecting assembly 2, and the drive assembly 3 drives the sampling drill bit 13 to rotate. The front end of the sampling drill bit 13 is flush with the front end of the sampling sleeve 11. The rear end of the sampling sleeve 11 is fitted onto the front end of the drive assembly 3. The clamping nut 12 is connected to the front end of the drive assembly 3 through threads and fixes the sampling sleeve 11 to the outer wall of the sampling drill bit 13. There is a gap between the outer wall of the sampling drill bit 13 and the inner wall of the sampling sleeve 11. The driving component 3 provides the power for automatic rotation, and the sampling component 1 facilitates accurate sampling of different parts such as the sample surface, fat layer, and muscle layer. The connecting component 2 connects and fixes the sampling component 1.
[0020] like Figure 3 and Figure 4 As shown, the sampling drill bit 13 includes: a cutting edge 131, a body 132 and a connecting shaft 133. The cutting edge 131 is fixedly disposed at the front end of the body 132 and the connecting shaft 133 is fixedly disposed at the rear end of the body 132. The body 132 is cylindrical, and at least one spiral groove 134 is provided on the outer wall of the body 132. The connecting shaft 133 is matched and fixed with the connecting assembly 2. Samples at different depths are taken by the cutting blade 131, the samples are transported by the spiral groove 134, and the connecting shaft 133 is connected to the drive assembly 3 to provide power to the cutting blade 131.
[0021] The cutting edge 131 is a triangular cutting edge with a longitudinal cross-section that protrudes from the front end of the body 132. There are two cutting edges 131, which are symmetrically arranged at the front end of the body 132. The arrangement of the cutting edges 131 facilitates sampling of samples at different depths.
[0022] In practical implementation, the longitudinal section of the cutting blade 131 is a right-angled triangle, with the height of the right-angled side of the cutting blade 131 being 0.8mm-1.2mm and the length of the bottom of the cutting blade 131 being 0.2mm. Meanwhile, the front end of the body 132 is flat. This design facilitates sampling of different layers and depths of meat. For example, when sampling the skin of meat, simply pressing the cutting blade 131 down to the skin position will cut through the skin without mixing in other parts.
[0023] The spiral groove 134 is disposed between the two cutting blades 131; The spiral groove 134 has a "V" shaped cross-section and is spirally arranged along the outer wall of the body 132. The cut sample is transported to the discharge port 113 through the spiral groove 134, which is safer and more convenient.
[0024] In the specific implementation process, there are two spiral grooves 134. Assuming that the two cutting blades 131 are in a vertical state, the endpoints of the spiral grooves 134 are located on the left and right sides of the middle of the two cutting blades 131, and the end point of the spiral grooves 134 is located at the rear end of the body 132.
[0025] like Figure 5 As shown, the sampling sleeve 11 includes: a receiving cavity 111, an installation cavity 112 and a discharge port 113. The receiving cavity 111 is provided at the front end of the sampling sleeve 11, the installation cavity 112 is provided at the rear end of the sampling sleeve 11, and the discharge port 113 is provided on the outer wall of the sampling sleeve 11. The discharge port 113 is connected to the receiving cavity 111. The receiving cavity 111 is a cylindrical mounting hole 22, and the sampling drill bit 13 is placed inside the receiving cavity 111; The mounting cavity 112 is fitted onto the front end of the drive assembly 3. The accommodating cavity 111 is used to place the sampling drill bit 13, which is safer and more reliable, and the discharge port 113 facilitates the removal of the cut sample.
[0026] The outer wall of the rear end of the sampling sleeve 11 is provided with a limiting protrusion 114, and the clamping nut 12 fits and presses against the limiting protrusion 114 and is threadedly connected to the front end of the drive assembly 3.
[0027] The connecting component 2 includes a pad 21, a mounting hole 22, and a limiting pin 23. The mounting hole 22 is arranged radially along the connecting shaft 133. The limiting pin passes through the mounting hole 22 and connects to the output end of the drive component 3. The pad 21 is sleeved on the outer wall of the connecting shaft 133 and is located between the rear end of the body 132 and the output end of the drive component 3. The limiting pin 23 enables transmission between the output end of the drive component 3 and the sampling drill bit 13, while the pad 21 provides support to ensure smooth rotation of the sampling drill bit 13.
[0028] Drive component 3 is a straight shank drill. Setting it to a straight shank drill makes operation more convenient. Drills typically come in two types: straight shank and "gun" shaped. Using a straight shank drill, similar to holding a pen, makes sampling easier and more precise.
[0029] During sampling, fish is used as an example, but the working surface is not limited to fish. The homogenizer end is placed on the body surface of the fish to be tested. The sampling sleeve 11 has four evenly arranged triangular tips at its end. Gently press the homogenizer so that the tips of the sampling sleeve 11 press against the fish body surface, which fixes the homogenizer and prevents it from slipping during operation. Then, the drive assembly 3 is turned on to operate. The customized end has two cutting blades 131, which are used to break the skin and extract samples in layers. The fish meat sample will move towards the end closer to the drive assembly 3 through the spiral groove 134. Then, the pad 21 ensures that the sampling drill 13 rotates smoothly while confining the meat in the receiving cavity 111. The sample is extracted through the discharge port 113 on the sampling sleeve 11 by attaching the sampling test tube at the discharge port 113.
[0030] The above descriptions are merely some embodiments of this utility model. It should be noted that those skilled in the art can make other modifications and improvements without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
