Description

Technical Field

[0001] This utility model relates to the field of seafood testing, and in particular to a seafood testing sample extraction device. Background Technology

[0002] Seafood safety testing, as a crucial means of ensuring seafood safety, is playing an increasingly important role. Currently, there are two main development trends in international seafood safety testing technology: one is laboratory testing, with increasingly sophisticated equipment, gradually shortening test times, and lowering detection limits; the other is rapid on-site testing, with continuously improving rapid testing techniques and increasingly portable equipment, resulting in a large number of rapid testing technologies and products. When testing seafood, sample extraction devices are required to collect samples.

[0003] When testing existing canned seafood, the testing personnel usually open the lid first and then pour the product from the can into the testing dish.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1 to 6 The illustrated seafood testing sample extraction device includes a base 1 for placing a can of seafood 16. The base 1 consists of a horizontal base plate and a vertically placed inverted L-shaped mounting plate. The mounting plate is fixed to the top of the base plate, and the can of seafood 16 is placed on the base 1.

[0025] A horizontal push plate 2 is slidably mounted on the mounting plate, and a power mechanism is provided between the push plate 2 and the mounting plate to drive the push plate 2 to slide in the vertical direction.

[0026] Specifically, the power mechanism includes a motor 6, which is fixedly mounted on the top of the push plate 2. An intermediate shaft 17 is rotatably mounted on the push plate 2, and the output shaft of the motor 6 is connected to the intermediate shaft 17 for transmission.

[0027] A first pulley 9 is fixedly mounted on the output shaft of motor 6, and a second pulley 10 is fixedly mounted on intermediate shaft 17. The first pulley 9 and the second pulley 10 are driven and connected within the same belt 5.

[0028] A gear compartment is opened inside the push plate 2, and a first gear 7 and a second gear 13 are installed in the gear compartment.

[0029] The intermediate shaft 17 extends downwards into the gear compartment, and the second gear 13 is fixedly mounted on the intermediate shaft 17. The first gear 7 is rotatably connected to the push plate 2 via a bearing 18, that is, the first gear 7 is coaxially and fixedly connected to the outer ring of the bearing 18, and the inner ring of the bearing 18 is fixedly connected to the push plate 2. The second gear 13 meshes with the first gear 7.

[0030] A lead screw 4 and a guide rod 3 are vertically placed between the top of the mounting plate and the bottom plate. The top ends of the lead screw 4 and the guide rod 3 are fixedly connected to the top of the mounting plate, and the bottom ends of the lead screw 4 and the guide rod 3 are fixedly connected to the bottom plate.

[0031] Both the lead screw 4 and the guide rod 3 pass through the push plate 2, and the push plate 2 is in sliding engagement with the lead screw 4 and the guide rod 3. The push plate 2 does not contact the lead screw 4, and the push plate 2 is in a limiting sliding engagement with the guide rod 3.

[0032] The lead screw 4 coaxially passes through the first gear 7 and the bearing 18. The first gear 7 is threadedly connected to the lead screw 4, and the bearing 18 is sleeved on the outside of the lead screw 4.

[0033] A vertically mounted conical rod 12 is rotatably installed on the push plate 2. The conical rod 12 penetrates downward through the push plate 2, and its bottom end is a cone. A matching drill bit 20 is fixedly installed at the bottom end of the cone. The seafood can 16 is located below the drill bit 20.

[0034] The cone rod 12 is driven by the second gear 13 of the power mechanism through a linkage. Specifically, the linkage includes a third gear 14, which is fixedly sleeved on the cone rod 12 and located in the gear compartment. The third gear 14 meshes with the second gear 13.

[0035] A connecting ring 11 is fixedly sleeved at the top of the tapered rod 12, and the inner curved surface of the connecting ring 11 is threaded. The connecting ring 11 is coaxially threaded to the sampling tube 8. In this embodiment, the sampling tube 8 is a needleless syringe.

[0036] The cone rod 12 is hollow inside, and the sampling tube 8 is connected to the hollow part inside the cone rod 12. An opening is opened at the top of the cone rod 12, which connects the hollow part of the cone rod 12 and the inside of the connecting ring 11. The sampling tube 8 blocks the opening.

[0037] Multiple sampling ports 21 are opened on the rod body of the cone rod 12 located below the push plate 2, and each sampling port 21 is connected to the hollow part inside the cone rod 12.

[0038] Multiple sampling ports 21 are evenly distributed in layers on the cone rod 12 to reduce the probability of the sampling ports 21 being blocked.

[0039] A horizontal pressure plate 15 is fixedly installed at the bottom of the push plate 2. A circular through hole is opened in the middle of the pressure plate 15, and the cone rod 12 passes through the circular through hole. A silicone gasket 19 is fixedly installed at the bottom of the pressure plate 15. The silicone gasket 19 is sleeved on the outside of the cone rod 12 and coaxially connected with the circular through hole.

[0040] Working principle: When it is necessary to test the seafood inside the canned seafood 16, this extraction device is used to sample the seafood inside the canned seafood 16. First, place the canned seafood 16 on the bottom plate of the base 1, so that the canned seafood 16 is directly below the cone rod 12. Next, screw the sampling tube 8 onto the connecting ring 11 until the sampling tube 8 is tightened.

[0041] Next, motor 6 is started. The output shaft of motor 6 drives the first pulley 9 to rotate, and the first pulley 9 drives the second pulley 10 to rotate via belt 5. The second pulley 10 drives the intermediate shaft 17 to rotate, and the intermediate shaft 17 drives the second gear 13 to rotate. The second gear 13 simultaneously drives the first gear 7 and the third gear 14 to rotate.

[0042] Since the first gear 7 is threadedly connected to the lead screw 4, when the first gear 7 rotates, it moves downward and drives the push plate 2 to slide down. The push plate 2 drives the cone rod 12 to move downward and approach the seafood can 16.

[0043] When the third gear 14 rotates, it drives the cone rod 12 to rotate, and the cone rod 12 drives the drill bit 20 to rotate.

[0044] When the drill bit 20 at the bottom of the cone rod 12 contacts the seafood can 16, the inspector holds the seafood can 16. At this time, the drill bit 20 drills a hole in the seafood can 16 and simultaneously penetrates into the seafood can 16. Subsequently, the cone at the bottom of the cone rod 12 enlarges the drill hole until the drill hole matches the cone rod 12. Then, the cone rod 12 is inserted into the seafood can 16 along the drill hole.

[0045] When the silicone gasket 19 comes into contact with and is squeezed against the seafood can 16, all sampling ports 21 are submerged in the seafood. At this time, the motor 6 is turned off. The inspector removes their hands from the seafood can 16 and simultaneously pulls the lever on the sampling tube 8 upwards. During this process, the liquid inside the seafood can 16 is sequentially drawn into the sampling tube 8 through the sampling ports 21 and the hollow part of the cone rod 12.

[0046] After extracting the specified amount of sample, simply unscrew the sampling tube 8 from the connecting ring 11.

[0047] After sampling, the sampling personnel hold the seafood can 16 again, while the output shaft of the motor 6 reverses, the push plate 2 slides upward, and the cone rod 12 drives the drill bit 20 upward and finally slides out of the seafood can 16. During this process, the seafood on the cone rod 12 can be scooped off by the can body of the seafood can 16.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
