[0027] See also Figure 1-6As shown, a sampling device for detecting drug residues in pork comprises a shell 1, an inner wall of the shell 1 is fixedly connected with a partition 2, the partition 2 can divide the inner cavity of the shell 1 into two independent spaces, an electric push rod 3 is installed at the center of the bottom of the partition 2, the output shaft of the electric push rod 3 is bolted with a sampling shell 4, the inner cavity of the sampling shell 4 is provided with an arc-shaped blade group 5, both sides of the arc-shaped blade group 5 are fixedly connected with a rotating shaft 6, the other ends of the rotating shafts 6 on both sides penetrate to the outside of the sampling shell 4 and are rotatably connected with the penetration, the surface of the sampling shell 4 is provided with a power mechanism 7, the power mechanism 7 is used in conjunction with one side of the rotating shaft 6, when in use, the electric push rod 3 is used to push the sampling shell 4 downward to the bottom of the shell 1, so that the bottom of the sampling shell 4 can be in contact with and fit with the surface of the pork to be sampled. At this time, the power mechanism 7 can drive the arc blade group 5 to rotate in the inner cavity of the sampling shell 4 through the rotating shaft 6. When the arc blade group 5 rotates one hundred and eighty degrees in the inner cavity of the sampling shell 4, the arc blades of the arc blade group 5 can cut the pork. The arc blade group 5 includes three arc blades fixedly connected to each other. The inclination angle between the three arc blades of the arc blade group 5 is sixty degrees, so that a semicircular structure can be formed between the arc blades of the arc blade group 5, so that the cut pork can be retained in the inner cavity of the sampling shell 4 for temporary storage. Slide bars 11 are bolted on both sides of the surface of the sampling shell 4, and the slide bars 11 on both sides are symmetrically distributed with respect to the center of the sampling shell 4. Slide slot frames 12 are bolted on both sides of the inner wall of the shell 1. The slide bars 11 and the slide slot frames 12 The positions and shapes of the two are corresponding, and they are slidably connected to each other. The length of the slide bar 11 is greater than the length of the slide slot frame 12. When the electric push rod 3 pushes the sampling shell 4 to move, the slide bar 11 will slide along the inner wall of the slide slot frame 12. Under the limitation of their own shapes, the stability of the movement of the sampling shell 4 can be improved. Moreover, when the power mechanism 7 drives the arc blade group 5 to cut pork through the rotating shaft 6, under the limitation of the slide bar 11 and the slide slot frame 12, the stability of the arc blade group 5 in cutting pork can also be improved. Handles 14 are bolted on both sides of the surface of the shell 1. There are two handles 14 and they are symmetrically distributed around the center of the shell 1. The handles 14 can be used to facilitate the staff to control or carry the shell 1.

When the arc-shaped blade group 5 cuts the pork into the inner cavity of the sampling shell 4, the electric push rod 3 can drive the sampling shell 4 to retract into the inner cavity of the shell 1. At this time, the torsion spring hinge 13 can provide force through its own torsion spring, so that the sealing door 10 can automatically return to the initial position of fitting with the bottom of the shell 1 after opening, so that the lower part of the inner cavity of the shell 1 is in a closed state, thereby providing a protective effect for the pork temporarily stored in the sampling shell 4. A magnet 17 is embedded at the bottom of the inner wall of the shell 1. The material of the sealing door 10 is nickel-iron alloy. When the sealing door 10 fits with the bottom of the shell 1, it is attracted by the magnetic force between the magnet 17 and the sealing door 10.The stability of the sealing door 10 closing the bottom of the shell 1 can be further improved. The top of the partition 2 is fixedly connected with a water tank 8. Antifreeze or other liquid media can be injected into the water tank 8 when in use. The surface of the water tank 8 is provided with a cooling mechanism 9. The cooling mechanism 9 can keep the inside of the shell 1 at a low temperature. The low temperature can slow down the growth and reproduction rate of bacteria, thereby reducing the possibility of microbial contamination of the pork temporarily stored in the sampling shell 4, thereby improving the stability and reliability of the pork sample.

[0028] The power mechanism 7 includes a driving motor 71, which is bolted to the top of the sampling shell 4 through a supporting frame, and the output shaft of the driving motor 71 is fixedly connected to a rotating rod 72, and a connecting plate 75 is bolted to the surface of the sampling shell 4, and the number of connecting plates 75 is two. The bottom end of the rotating rod 72 passes through the bottom of the two connecting plates 75 and is fixedly connected to the penetration point through a bearing, and the bottom end of the rotating rod 72 is bolted with a first bevel tooth 73, and one end of the rotating shaft 6 on one side is bolted with a second bevel tooth 74, and the first bevel tooth 73 and the second bevel tooth 74 mesh with each other. When the driving motor 71 provides power to drive the rotating rod 72 to rotate, the power of the driving motor 71 can be transmitted to the rotating shaft 6 through the meshing connection of the first bevel tooth 73 and the second bevel tooth 74, so that the arc-shaped blade group 5 can be rotated around the rotating shaft 6, thereby enabling the sampling shell 4 to be rotated. 4, the pork at the bottom is automatically cut, and there is no need to manually cut the pork, which can not only improve the efficiency of pork sampling, but also reduce the chance of people contacting the pork sample, thereby reducing the potential risk of cross contamination. The rotation connection between the connecting plate 75 and the rotating rod 72 can further improve the stability of the meshing transmission between the first bevel gear 73 and the second bevel gear 74. When it is necessary to take the sampled pork out of the interior of the sampling shell 4, the electric push rod 3 can be used to push the sampling shell 4 to the bottom of the shell 1, and then the arc blade group 5 is rotated to the top of the inner cavity of the sampling shell 4 through the cooperation of the driving motor 71, the rotating rod 72, the first bevel gear 73, the second bevel gear 74 and the rotating shaft 6.

[0029] The cooling mechanism 9 includes a semiconductor cooling sheet 91, which is located above the water tank 8. The cooling side of the bottom of the semiconductor cooling sheet 91 is bolted to the top of the water tank 8, and the heating side of the top of the semiconductor cooling sheet 91 is installed with heat dissipation fins. When the semiconductor cooling sheet 91 is running, the cooling surface at the bottom can cool the liquid medium in the water tank 8. An exhaust grille 15 is provided on the top of the shell 1, and air inlet holes 16 are provided on the upper sides of the shell 1. Through the arrangement of the exhaust grille 15 and the air inlet holes 16, air above the semiconductor cooling sheet 91 can flow, so that the heating surface of the semiconductor cooling sheet 91 can be dissipated. A fan 18 is installed in the inner cavity of the shell 1 and located above the semiconductor cooling sheet 91 through a support frame. The fan 18 can accelerate the flow of air, thereby further enhancing the heating of the semiconductor cooling sheet 91. In order to achieve the heat dissipation effect on the surface, a circulation pump 92 is bolted on one side of the top of the partition 2, the water inlet end of the circulation pump 92 is communicated with the water tank 8, and the water outlet end of the circulation pump 92 is connected with a water pipe 93, the other end of the water pipe 93 passes through the bottom of the partition 2, the water pipe 93 is serpentine in design, and it fits along the four surfaces of the inner wall of the shell 1, the other end of the water pipe 93 passes through the top of the partition 2 and is communicated with the water tank 8, when the circulation pump 92 is running, the low-temperature liquid in the water tank 8 can be pumped through the water pipe 93 along the inner wall of the shell 1 for transportation, and finally the water pipe 93 discharges the liquid to the inside of the water tank 8 to form a closed loop, so that the temperature of the inner cavity of the shell 1 can be rapidly reduced, the temperature of the pork sample in the sampling shell 4 can be effectively reduced, the growth rate of microorganisms can be slowed down, thereby reducing the risk of microbial contamination, thereby improving the stability and reliability of pork quality.

[0030] Working principle: first, lift the device through the handle 14 and place it above the pork to be sampled, then start the electric push rod 3 to extend its output end to push the sampling shell 4 to the bottom of the shell 1. During this process, the slide bars 11 on both sides of the sampling shell 4 will slide in the inner wall of the slide frame 12, and the bottom end of the slide bar 11 will first contact the sealing door 10 to push it to an open state, then the sampling shell 4 is fitted with the surface of the pork to be sampled, and then the drive motor 71 is started to drive the rotating rod 72 to rotate, and through the meshing transmission of the first bevel gear 73 and the second bevel gear 74, the rotating shaft 6 can drive the arc blade group 5 to rotate one hundred and eighty degrees in the inner cavity of the sampling shell 4, so that the pork can be cut, and the cut pork can be temporarily stored in the sampling shell 4 under the action of the shape of the arc blade group 5, and then the stroke of the electric push rod 3 is retracted to shrink the sampling shell 4 to the inner cavity of the shell 1, and then the sampling shell 4 is retracted to the inner cavity of the shell 1. Under the action of the torsion spring hinge 13, the sealing door 10 can automatically return to the state of being in contact with the bottom of the shell 1, so as to protect the pork sample in the sampling shell 4. The pork can be automatically cut, which can not only improve the efficiency of pork sampling, but also reduce the chance of people contacting the pork sample. When it is necessary to cool and preserve the pork in the sampling shell 4, the semiconductor refrigeration chip 91 and the circulation pump 92 are started first. The semiconductor refrigeration chip 91 can reduce the temperature of the liquid in the water tank 8, and the circulation pump 92 pumps the low-temperature liquid in the water tank 8 through the water pipe 93, which can quickly reduce the temperature of the inner cavity of the shell 1. Finally, the liquid in the water pipe 93 is discharged into the water tank 8 to form a closed loop effect, so that the pork sample in the sampling shell 4 can be placed in a lower ambient temperature, which can reduce the risk of microbial contamination, thereby improving the stability and reliability of the quality of the pork to be inspected.
