Detailed Embodiments

[0027] Embodiment 1

[0028] As Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, a continuous detection device for pickled duck claws soaking juice proposed in this embodiment includes a frame 1, a conveyor belt 2, a heavy metal analysis and detection instrument 7, a first collection box 8, a second collection box 9, a limit plate 33, a sampling mechanism, multiple sets of clamping components, and multiple sets of pushing components.

[0029] A driving component for driving the rotation of the conveyor belt 2 is installed on the frame 1. The driving component includes a first servo motor 301 and two transmission rollers 302. Both transmission rollers 302 are rotatably installed on the frame 1. The conveyor belt 2 is sleeved and installed on the two transmission rollers 302. The first servo motor 301 is installed on the frame 1 and its output shaft is connected to the rotating shaft of the transmission roller 302.

[0030] Multiple sets of clamping components are evenly distributed on the outer periphery of the conveyor belt 2. The clamping component includes a base 22, two first arc-shaped clamping plates 21, and two sets of elastic connecting pieces. A support rod 39 is connected between the base 22 and the conveyor belt 2. The two first arc-shaped clamping plates 21 are symmetrically arranged and both are slidably installed on the base 22. The two first arc-shaped clamping plates 21 are elastically connected through two sets of elastic connecting pieces. The elastic connecting piece includes a slide rod 25, two springs 26, and two first fixing plates 24. The two first fixing plates 24 are arranged side by side on the base 22. The slide rod 25 is connected between the two first fixing plates 24. The two springs 26 are respectively sleeved and installed at both ends of the slide rod 25. Both ends of the first arc-shaped clamping plate 21 are connected with connecting sliders 31. The two connecting sliders 31 on the same side are both slidably installed on the corresponding slide rod 25. Two limit rings 30 are arranged side by side on the slide rod 25; a limit seat 23 is arranged on the inner side wall of the first arc-shaped clamping plate 21. By setting the limit seat 23, the test tube can be limited, so that the triangular plate 27 can be smoothly inserted into the bottom between the two first arc-shaped clamping plates 21.

[0031] Multiple sets of pushing components are respectively installed on multiple bases 22. The pushing component includes a triangular plate 27, a second fixing plate 28, and a push rod 29. The second fixing plate 28 is arranged at the edge of the base 22. The push rod 29 movably penetrates through the second fixing plate 28. The triangular plate 27 is connected to the end of the push rod 29; the limit plate 33 is connected to the frame 1, and one side of the limit plate 33 is a bent structure.

[0032] Both the first collection box 8 and the second collection box 9 are arranged below the conveyor belt 2; the heavy metal analysis and detection instrument 7 is installed on the side of the frame 1; the sampling mechanism is installed on the frame 1.

[0033] The upper ends of the first arc-shaped clamping plates 21 are all inclined and connected with second arc-shaped clamping plates 32. Two adjacent second arc-shaped clamping plates 32 form a "V" structure. Place the test tube between the two second arc-shaped clamping plates 32, and then push the test tube downward. The test tube will move along the inclined surface of the second arc-shaped clamping plate 32 until the bottom of the test tube is placed between the two first arc-shaped clamping plates 21. Through the setting of the above structure, the test tube is convenient to be inserted between the two first arc-shaped clamping plates 21.

[0034] When detecting heavy metals in the soaking juices of multiple sample marinated duck claws, place the test tube containing the sample between the two first arc-shaped clamping plates 21. Under the elastic force of the elastic connection assembly, the test tube is clamped between the two first arc-shaped clamping plates 21. The driving assembly drives the conveyor belt 2 to rotate, thereby driving the movement of multiple test tubes. When the test tube moves below the sampling mechanism, the sampling mechanism sucks the sample in the test tube and drops it into the sample adding port of the heavy metal analysis and detection instrument 7 for detection. When the test tube starts to rotate downward, the excess sample in the test tube flows into the inner side of the second collection box 9. When the test tube moves close to the limit plate 33, the push rod 29 starts to contact the inclined surface of the limit plate 33, causing the push rod 29 to start moving gradually, thereby driving the triangular plate 27 to move. The triangular plate 27 moves to squeeze the two first arc-shaped clamping plates 21, thereby releasing the clamping work on the test tube. At this time, the test tube separates from between the two first arc-shaped clamping plates 21 and falls into the inner side of the first collection box 8, thus realizing the collection work of the test tube.

The turntable 4 is rotatably installed on the base. The second servo motor 37 is installed on the base and is used to drive the turntable 4 to rotate. The plurality of straw assemblies are installed on the turntable 4 in a circular array. The straw assembly includes a cylinder body 6, a thin tube 61, a sealing piston 34, and a connecting rod 35. The cylinder body 6 penetrates through the upper and lower ends of the turntable 4. The thin tube 61 is communicated with the cylinder body 6. The sealing piston 34 is movably arranged inside the cylinder body 6. The top plate 5 is located above the turntable 4. The first linear driving mechanism 18 is installed on the turntable 4 and is used to drive the top plate 5 to move up and down. The connecting rod 35 is connected between the sealing piston 34 and the top plate 5. When sampling the sample in the test tube, the second linear driving mechanism 36 drives the turntable 4 to move upward, thereby driving the plurality of straw assemblies to move upward until the straw assemblies move above the test tube. Subsequently, the second servo motor 37 is used to drive the turntable 4 to rotate until the straw assembly rotates to the position directly above the test tube. The second linear driving mechanism 36 drives the straw assembly downward so that the thin tube 61 is inserted into the test tube. The first linear driving mechanism 18 works to drive the top plate 5 to move upward, thereby driving the sealing piston 34 to move upward. The upward movement of the sealing piston 34 can suck a certain amount of sample in the test tube. Subsequently, the thin tube 61 is driven to move out of the test tube, and then the test tube assembly is driven to move to the sample injection port of the heavy metal analysis and detection instrument 7 for detection, thereby realizing the automatic sampling work of the sample.
