Description

Technical Field

[0001] This invention relates to the field of shellfish detection technology, specifically to a device and method for measuring the carbon content of shellfish. Background Technology

[0002] As the largest carbon sink on Earth, the ocean is a crucial link in the global carbon cycle, with marine life playing a key role. Shellfish, in particular, utilize carbonate ions from seawater and filter-feed particulate organic carbon to form shells primarily composed of calcium carbonate, thus acting as carbon sinks. Therefore, marine shellfish aquaculture is an important pathway for carbon sequestration in marine fisheries and is of great significance for research on marine biological carbon sequestration and carbon fixation.

[0003] X-ray fluorescence spectrometry can be used to detect the carbon content of shellfish. However, with traditional X-ray fluorescence spectrometry, when changing samples, staff need to manually open the instrument's top cover, remove the previous sample from the sample chamber, accurately place the next sample on the sample chamber, and then close the instrument's top cover. The whole process is very cumbersome. Furthermore, when detecting the carbon content of shellfish, there are many types of shellfish that need to be tested, which requires staff to place the samples accurately, greatly increasing the workload of the staff.

[0004] Based on this, the present invention designs a device and method for measuring the carbon content of shellfish to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a device and method for measuring the carbon content of shellfish, so as to solve the problems of the shortcomings of the prior art mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for measuring the carbon content of shellfish, comprising a body, a feeding assembly for single feeding, a transfer assembly, and a driving assembly for driving the feeding assembly and the transfer assembly. A detection chamber is formed on the upper surface of the body, and a cover is rotatably mounted at the rear end of the detection chamber. A sample chamber is formed on the lower surface of the detection chamber. The feeding assembly includes a mounting plate, a discharge plate, and a separation assembly for separating the discharge plates. A vertical groove communicating with the lower surface is formed on the upper surface of the cover. The mounting plate is vertically slidably mounted in the vertical groove. Multiple longitudinal grooves are vertically arrayed on the mounting plate. Two discharge plates are vertically slidably mounted in the longitudinal grooves. A first reset spring for resetting the discharge plates is fixedly installed between the front and rear discharge plates. The left side of the discharge plate... The first contact plate is fixedly installed at the end. The separation assembly includes a separation rod, a sliding rod for mounting the separation rod, a sliding frame for mounting the sliding rod, and a squeezing assembly for squeezing the sliding rod to move to the right. A sliding frame is fixedly installed on the left side of the lower surface of the detection chamber. Two sliding frames are symmetrically installed about the central axis of the sample chamber. Multiple sliding rods are laterally elastically slidably installed between the two sliding frames. Two separation rods are elastically rotatably installed on the right side of the sliding rod. The transfer assembly includes a rotating frame, a transfer plate, and a positioning action assembly. The rotating frame is used to rotate the transfer plate to be installed on the lower surface of the detection chamber. The positioning action assembly can place the sample above the transfer plate onto the sample chamber when the transfer plate rotates to the top of the sample chamber. The driving assembly is used to drive the squeezing assembly and the rotating frame to rotate.

[0007] As a further embodiment of the present invention, the extrusion assembly includes a rotating rod and a first cam for extruding the sliding rod. The rotating rod is rotatably mounted on the lower surface of the detection chamber, and a plurality of first cams are fixedly mounted on the rotating rod. The number of first cams is the same as the number of sliding rods.

[0008] As a further embodiment of the present invention, the two adjacent first cams have the same angular difference;

[0009] As a further embodiment of the present invention, the positioning action component includes a rotating plate, a blocking block, and a third return spring. The rotating plate is rotatably mounted on the upper side of the rotating frame. A transverse groove is formed on the front surface of the rotating plate. Two material transfer plates are slidably mounted in the transverse groove. A second return spring is fixedly mounted between the left and right material transfer plates. A second contact plate is fixedly mounted on the rear surface of the material transfer plates. A second cam is rotatably mounted in the middle of the mounting plate. A misaligned gear is fixedly mounted on the lower surface of the second cam. A misaligned rack that meshes with the misaligned gear is fixedly mounted on the front surface of the rotating frame. A third return spring is fixedly mounted on the left surface of the rotating plate. The end of the third return spring away from the rotating plate is fixedly connected to the rotating frame. An installation rod is fixedly mounted on the upper surface of the inner cavity of the machine cover. A blocking block is slidably mounted vertically on the lower end of the installation rod. A pressing slope is formed on the lower surface of the blocking block.

[0010] As a further embodiment of the present invention, a synchronous screw is rotatably installed in the transverse groove, and the transfer plate is threadedly connected to the synchronous screw. The threaded connection between the transfer plate and the synchronous screw does not have self-locking property. At the same time, the threads of the synchronous screw rotate in opposite directions from the middle to the left and right ends, and the left and right transfer plates respectively mesh with threads of different directions.

[0011] As a further embodiment of the present invention, a discharge ring is fixedly installed on the rear surface of the rotating frame, and a discharge port is opened on the front side of the lower surface of the detection chamber, the discharge port being connected to the front surface of the machine body;

[0012] As a further embodiment of the present invention, the drive assembly includes a drive motor, an incomplete gear, a separation gear, and a separation rack. The output shaft of the drive motor is directly fixedly connected to the lower surface of the rotating frame. An installation groove is formed in the inner cavity of the machine body. The lower end of the rotating rod extends into the installation groove. The separation gear is fixedly installed on the lower surface of the rotating rod. The lower surface of the separation gear is fixedly connected to a rotation damper. The separation rack is longitudinally slidably installed in the installation groove. The incomplete gear is rotatably installed in the installation groove. The incomplete gear meshes with the separation rack. Multiple pawls are fixedly installed on the right surface of the separation rack. The separation rack meshes with the separation gear in one direction through the pawls. An energy storage spring is fixedly installed on the rear surface of the separation rack. The incomplete gear and the drive motor are driven by a synchronous belt.

[0013] As a further embodiment of the present invention, protrusions are fixedly installed at the lower ends of the front and rear surfaces of the mounting plate, a top block is vertically slidably installed on the lower surface of the detection cavity, a compression spring is fixedly installed on the lower surface of the top block, an unlocking rack is longitudinally slidably installed on the left side of the vertical groove on the upper surface of the inner cavity of the cover, a locking block is elastically slidably installed on the right surface of the unlocking rack, a locking groove is opened at the upper end of the left surface of the mounting plate, and an unlocking gear for meshing with the unlocking gear is fixedly installed on the upper surface of the rotating rod.

[0014] A method for using a device for measuring the carbon content of shellfish, the specific steps of which are as follows:

[0015] Step 1: The staff places the shell sample to be tested on the feeding plate. Each feeding plate can hold a maximum of one shell sample. Then, the mounting plate is pressed vertically downward into the vertical groove opened in the machine cover. When the locking block is engaged in the locking groove opened on the left surface of the mounting plate, the mounting plate installation is completed.

[0016] Step 2: Next, the drive assembly will drive the rotating frame to rotate 90 degrees and then stop. The transfer plate will rotate to the bottom of the bottom feeding plate. At the same time, the drive assembly will drive the rotating rod to rotate one revolution. Under the rotation of the cam, the feeding plates will open from bottom to top. The shell samples on the feeding plates will move to the next feeding plate, while the shell samples on the bottom feeding plate will fall onto the transfer plate.

[0017] Step 3: The drive assembly drives the rotating frame to rotate 270 degrees again. The transfer plate will rotate back to the initial position from below the feeding plate. The transfer plate will pass over the sample chamber. When the transfer plate rotates to the top of the sample chamber, the blocking block will block the rotating plate. The rotating frame will continue to move and separate the two transfer plates. Then the shell samples on the transfer plates will fall onto the sample chamber.

[0018] Step 4: The machine examines the seashell samples in the sample chamber;

[0019] Step 5: When the drive assembly drives the rotating frame to rotate again to transport the shell sample to the sample chamber, the discharge ring located on the rear side of the rotating frame will take away the shell sample located on the sample chamber and then discharge it from the discharge port.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The operator only needs to insert the mounting plate into the vertical slot in the machine cover. The drive component can then transfer the shell samples on the feeding plate to the sample chamber through the extrusion component and the transfer component. After all the shell samples have been tested, the operator only needs to remove the mounting plate from the vertical slot, replenish the shell samples, and then insert it back into the vertical slot. The entire process does not require opening the machine cover. Furthermore, multiple feeding plates at different heights on the right side of the mounting plate can hold multiple shell samples, which reduces the frequency of sample replacement and greatly reduces the workload of the operators.

[0022] 2. Multiple first cams press the sliding rod, with the same angle difference between adjacent first cams. The contact time between the first cams at different heights and the sliding rod on their right is staggered, allowing the feeding plates to unfold sequentially from bottom to top. Thus, when the rotating rod rotates once, the shell samples on the feeding plates will descend one layer, achieving sequential feeding. The structure is simple and reliable. The positioning action component ensures that the rotating plate is accurately placed above the sample chamber before the two rotating plates separate, guaranteeing precise placement of the shell samples on the sample chamber. Simultaneously, a discharge ring is fixedly installed on the rear surface of the rotating frame, and a discharge port is opened on the front side of the lower surface of the detection chamber. When the drive component drives the rotating frame to rotate, the discharge ring located on the rear side of the rotating frame pushes the tested shell samples from the sample chamber into the discharge port, where they are then discharged. This achieves automatic discharge of tested samples, eliminating the need for personnel to open the machine cover to retrieve the materials. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 1-13This invention provides a technical solution: a device for measuring the carbon content of shellfish, comprising a body 1, a feeding assembly for single feeding, a transfer assembly, and a driving assembly for driving the feeding assembly and the transfer assembly. The device is characterized in that: a detection chamber 2 is formed on the upper surface of the body 1, a cover 3 is rotatably mounted at the rear end of the detection chamber 2, a sample chamber 4 is formed on the lower surface of the detection chamber 2, the feeding assembly includes a mounting plate 5, a discharge plate 6, and a separation assembly for separating the discharge plates 6, a vertical groove 7 communicating with the lower surface is formed on the upper surface of the cover 3, the mounting plate 5 is vertically slidably mounted in the vertical groove 7, the mounting plate 5 has multiple vertically arranged slots, two discharge plates 6 are vertically slidably mounted in the vertical grooves, a first reset spring 8 for resetting the discharge plate 6 is fixedly installed between the two discharge plates 6, a first contact plate 9 is fixedly installed at the left end of the discharge plate 6, and the separation assembly... The assembly includes a separating rod 10, a sliding rod 11 for mounting the separating rod 10, a sliding frame 12 for mounting the sliding rod 11, and a squeezing assembly for squeezing the sliding rod 11 to move to the right. The sliding frame 12 is fixedly mounted on the left side of the lower surface of the detection chamber 2. Two sliding frames 12 are symmetrically mounted about the central axis of the sample chamber 4. Multiple sliding rods 11 are laterally elastically slidably mounted between the two sliding frames 12. Two separating rods 10 are elastically rotatably mounted on the right side of the sliding rod 11. The transfer assembly includes a rotating frame 13, a transfer plate 14, and a positioning action assembly. The rotating frame 13 is used to rotate the transfer plate 14 to be mounted on the lower surface of the detection chamber 2. The positioning action assembly can lower the sample above the transfer plate 14 onto the sample chamber 4 when the transfer plate 14 rotates to the top of the sample chamber 4. The drive assembly is used to drive the squeezing assembly and the rotating frame 13 to rotate.

[0041] During operation, traditional X-ray fluorescence spectrometers require manual opening of the instrument's top cover for sample replacement. The previous sample must be removed from sample chamber 4, the next sample precisely placed in sample chamber 4, and then the instrument's top cover closed. This entire process is extremely cumbersome. Figure 11 As shown, this device involves creating a vertical groove 7 on the upper surface of the cover 3 that connects to the lower surface, and then vertically sliding the mounting plate 5 into the groove 7. Figure 4 As shown, a feeding plate 6 is longitudinally slidably installed on the right end of the mounting plate 5. Multiple feeding plates 6 are installed in a vertical array, allowing the operator to place a seashell sample on each feeding plate 6. Then, the mounting plate 5 is inserted vertically downwards into the vertical groove 7 in the cover 3. Next, the extrusion component is driven by the drive component. Figure 4As shown, the extrusion assembly pushes the slide bar to slide to the right between the two sliding frames 12. The spring on the left side of the slide bar will be stretched, and the separating rod 10 on the right side of the slide bar will contact the first contact plate 9 on the left side of the discharge plate 6. At this time, the separating rod 10 can no longer move to the right. If the slide bar continues to move to the right, the separating rod 10 will rotate. At this time, the distance between the right ends of the two separating rods 10 will become greater and greater. In this way, the two discharge plates 6 can be pushed apart by the two separating rods 10. Figure 5 As shown, the first reset spring 8 will be stretched, allowing the seashell sample on the feeding plate 6 to fall from the gap in the middle of the feeding plate 6 onto the next feeding plate 6. Simultaneously, the drive assembly, while driving the extrusion assembly, will also drive the rotating frame 13 to rotate. Figure 7 As shown, rotating the rotating frame 13 causes the transfer plate 14 to move in a circular motion around the rotation axis of the rotating frame 13, as follows. Figure 2 As shown, during the circular motion of the transfer plate 14, it will pass under the discharge plate 6. The shell sample falling from the lowest discharge plate 6 will land above the transfer plate 14. Then the transfer plate 14 will rotate with the shell sample to directly above the sample chamber 4. At this time, the positioning action component will control the two transfer plates 14 to separate, and then the shell sample on the transfer plate 14 will fall onto the sample chamber 4. Since there cannot be any obstructions within a certain distance above the sample chamber 4, the discharge plate 6 cannot be directly installed above the sample chamber 4. Therefore, the shell sample needs to be transferred through the rotating frame 13 and the transfer plate 14.

[0042] The operator only needs to insert the mounting plate 5 into the vertical slot 7 opened in the cover 3. The drive component can then transfer the shell samples on the feeding plate 6 to the sample chamber 4 through the extrusion component and the transfer component. After all the shell samples have been tested, the operator only needs to remove the mounting plate 5 from the vertical slot 7, replenish the shell samples, and then insert it back into the vertical slot 7. During the entire process, it is not necessary to open the cover 3. Furthermore, multiple feeding plates 6 at different heights on the right side of the mounting plate 5 can hold multiple shell samples, which reduces the frequency of sample replacement and greatly reduces the labor intensity of the operators.

[0043] As a further embodiment of the present invention, the extrusion assembly includes a rotating rod 16 and a first cam 15 for extruding the sliding rod 11. The rotating rod 16 is rotatably mounted on the lower surface of the detection cavity 2. A plurality of first cams 15 are fixedly mounted on the rotating rod 16. The number of first cams 15 is the same as the number of sliding rods 11. There is the same angle difference between two adjacent first cams 15.

[0044] At work, such as Figure 6As shown, rotating the first cam 15 pushes the sliding rod 11 to the right. At the same time, the two adjacent first cams 15 have the same angle difference. This ensures that the contact time between the first cams 15 at different heights and the sliding rod 11 on their right is staggered during the rotation of the rotating rod 16, so that the feeding plate 6 unfolds from bottom to top. Thus, when the rotating rod 16 rotates one revolution, the shell samples on the feeding plate 6 will descend one layer, realizing sequential feeding. The structure is simple and reliable.

[0045] As a further embodiment of the present invention, the positioning action assembly includes a rotating plate 17, a blocking block 25, and a third reset spring 23. The rotating plate 17 is rotatably mounted on the upper side of the rotating frame 13. A transverse groove is provided on the front surface of the rotating plate 17. Two material transfer plates 14 are slidably mounted in the transverse groove. A second reset spring 18 is fixedly mounted between the left and right material transfer plates 14. A second contact plate 19 is fixedly mounted on the rear surface of the material transfer plates 14. A second cam 20 is rotatably mounted in the middle of the mounting plate 5. A misaligned gear 21 is fixedly mounted on the lower surface of the second cam 20. A misaligned rack 22 that meshes with the misaligned gear 21 is fixedly mounted on the front surface of the rotating frame 13. A third reset spring 23 is fixedly mounted on the left surface of the rotating plate 17. One end of the third reset spring 23 away from the rotating plate 17 is fixedly connected to the rotating frame 13. An mounting rod 24 is fixedly mounted on the upper surface of the inner cavity of the machine cover 3. A blocking block 25 is slidably mounted vertically on the lower end of the mounting rod 24. A pressing slope 26 is provided on the lower surface of the blocking block 25.

[0046] At work, such as Figure 7 As shown, a rotating plate 17 is rotatably mounted on the upper side of the rotating frame 13. The rotating plate 17 is connected to the rotating frame 13 by a third return spring 23. Then, a transfer plate 14 is slidably mounted laterally on the front end of the rotating plate 17. During the rotation of the rotating frame 13, the rotating plate 17 can be driven to rotate synchronously. When the transfer plate 14 rotates to directly above the sample chamber 4, as shown... Figure 8 As shown, the blocking block 25 located on the upper surface of the cover 3 will contact the front end face of the rotating plate 17 through the pressing inclined surface 26. Since the third return spring 23 is in its natural state at this time, the rotating plate 17 will be blocked by the blocking block 25, while the rotating frame 13 will continue to rotate. At this time, an angle difference will appear between the rotating plate 17 and the rotating frame 13, and the third return spring 23 will be stretched. Figure 9 As shown, the misaligned gear 21 is rotatably mounted below the rotating plate 17, while the misaligned rack 22 is fixedly connected to the rotating frame 13. Therefore, a displacement difference will occur between the misaligned gear 21 and the misaligned rack 22, causing the misaligned rack 22 to drive the misaligned gear 21 to rotate. When the misaligned gear 21 rotates, it will drive the second cam 20 above it to rotate synchronously. Figure 10As shown, the rotation of the second cam 20 pushes the second contact plate 19 on the rear side of the transfer plate 14, thus separating the two transfer plates 14. The second return spring 18 will be stretched, and the shell sample on the transfer plate 14 can fall onto the sample chamber 4. As the angle difference between the transfer plate 17 and the transfer frame 13 increases, the third return spring 23 will be continuously stretched, and the elastic force of the third return spring 23 will continue to increase. When the elastic force of the third spring is sufficient to push the blocking block 25 upward, the transfer plate 17 will push the blocking block 25 upward by squeezing the inclined surface 26. Then, under the action of the elastic force of the third return spring 23, the transfer plate 17 will reset. At the same time, the second cam 20 will also rotate and reset to the initial state. The second return spring 18 will pull the two transfer plates 14 to reset. This allows the two transfer plates 14 to separate after the transfer plate 17 stops, ensuring that the shell sample can be accurately placed on the sample chamber 4.

[0047] As a further embodiment of the present invention, a synchronous screw 27 is rotatably installed in the transverse groove, and the transfer plate 14 is threadedly connected to the synchronous screw 27. The threaded connection between the transfer plate 14 and the synchronous screw 27 does not have self-locking property. At the same time, the threads of the synchronous screw 27 from the middle to the left and right ends are opposite, and the left and right transfer plates 14 respectively mesh with threads of different directions.

[0048] At work, such as Figure 10 As shown, since the threaded connection between the synchronizing screw 27 and the rotating plate 14 is not self-locking, the movement of one of the two rotating plates 14 can drive the synchronizing screw 27 to rotate. When the synchronizing screw 27 rotates, the other rotating plate 14 will also move synchronously. Since the threads of the synchronizing screw 27 turn in opposite directions from the middle to the left and right ends, the two rotating plates 14 will move in opposite directions when the synchronizing screw 27 rotates. In this way, the second cam 20 only needs to push one of the two rotating plates 14 to move, so as to achieve the opposite synchronous movement of the two rotating plates 14, reducing the length required for the second cam 20 and reducing the overall size of the device.

[0049] As a further embodiment of the present invention, a discharge ring 28 is fixedly installed on the rear surface of the rotating frame 13, and a discharge port 29 is opened on the front side of the lower surface of the detection chamber 2, and the discharge port 29 is connected to the front surface of the machine body 1.

[0050] At work, such as Figure 2 As shown, when the drive assembly drives the rotating frame 13 to rotate, the discharge ring 28 located on the rear side of the rotating frame 13 will push the shell samples that have been tested on the sample chamber 4 into the discharge port 29. Then the shell samples will be discharged from the discharge port 29. This can realize the automatic discharge of the tested samples without the need for staff to open the cover 3 to take out the materials.

[0051] As a further embodiment of the present invention, the drive assembly includes a drive motor 30, an incomplete gear 31, a separating gear 32, and a separating rack 33. The output shaft of the drive motor 30 is directly fixedly connected to the lower surface of the rotating frame 13. An installation groove is opened in the inner cavity of the body 1. The lower end of the rotating rod 16 extends into the installation groove. The separating gear 32 is fixedly installed on the lower surface of the rotating rod 16. The lower surface of the separating gear 32 is fixedly connected to the rotation damper 34. The separating rack 33 is longitudinally slidably installed in the installation groove. The incomplete gear 31 is rotatably installed in the installation groove. The incomplete gear 31 meshes with the separating rack 33. Multiple pawls 35 are fixedly installed on the right surface of the separating rack 33. The separating rack 33 meshes with the separating gear 32 in one direction through the pawls 35. An energy storage spring 36 is fixedly installed on the rear surface of the separating rack 33. The incomplete gear 31 and the drive motor 30 are driven by a synchronous belt.

[0052] During operation, the seashell samples are cut from seashells, so their size and shape cannot be exactly the same. Furthermore, the seashell samples cannot be perfectly centered when placed on the feeding plate 6. Therefore, the timing and position of the seashell samples falling from the feeding plates 6 when the two feeding plates 6 separate cannot be accurately controlled. Figure 3 As shown, we need to drive the rotating frame 13 to rotate 90 degrees first via the drive motor 30, so that the transfer plate 14 is rotated below the feeding plate 6. Then, during the process of the drive motor 30 driving the rotating frame 13 to rotate 90 degrees, the incomplete gear 31 will also rotate 90 degrees, as shown... Figure 6 As shown, the incomplete gear 31 will push the separating rack 33 forward, and the energy storage spring 36 will be stretched. Since the right side of the separating rack 33 is engaged with the separating gear 32 through the pawl 35, the separating gear 32 will not rotate during the forward movement of the separating rack 33. When the incomplete gear 31 rotates exactly ninety degrees, the incomplete gear 31 disengages from the separating rack 33. At this time, the transfer plate 14 is just below the discharge plate 6. The stretched energy storage spring 36 will pull the separating rack 33 backward, and the separating rack 33 will drive the separating rack 33 through the pawl 35 on the right side. When the separating gear 32 rotates, it drives the rotating rod 16 above it to rotate. The rotation damper below the separating gear 32 is to reduce the rotation speed of the separating gear 32 and prevent it from rotating too fast. The subsequent drive assembly will drive the rotating frame 13 and the incomplete gear 31 to rotate another 270 degrees. However, the incomplete gear 31 will not mesh with the energy storage rack. When the transfer plate 14 rotates to the bottom of the discharge plate 6, the rotating rod 16 will rotate again, so that the shell sample on the discharge plate 6 can be accurately placed on the transfer plate 14, ensuring the stability of the overall device.

[0053] As a further embodiment of the present invention, protrusions 37 are fixedly installed on the lower ends of the front and rear surfaces of the mounting plate 5, a top block 38 is vertically slidably installed on the lower surface of the detection cavity 2, a compression spring 39 is fixedly installed on the lower surface of the top block 38, an unlocking rack 40 is longitudinally slidably installed on the left side of the vertical groove 7 on the upper surface of the inner cavity of the cover 3, a locking block 41 is elastically slidably installed on the right surface of the unlocking rack 40, a locking groove 42 is opened on the upper end of the left surface of the mounting plate 5, and an unlocking gear 43 for meshing with the unlocking gear is fixedly installed on the upper surface of the rotating rod 16.

[0054] At work, such as Figure 11 As shown, when the mounting plate 5 slides downward in the vertical groove 7, the protrusions 37 on its front and rear sides will contact the upper surface of the top block 38. Then, the compression spring 39 under the top block 38 will be compressed. By engaging the locking block 41 on the right side of the unlocking rack 40 with the locking groove 42 on the left side of the mounting plate 5, the mounting plate 5 can be locked in the vertical groove 7. Then, when the rotating rod 16 rotates, it will push the unlocking rack 40 forward through the unlocking gear 43. When the unlocking rack 40 moves forward, it will drive the locking block 41 forward as well. When the locking block 41 disengages from the locking groove 42, the locking of the mounting plate 5 by the locking block 41 will disappear. The compressed spring 39 will push the mounting plate 5 upward. The forward movement distance of the locking block 41 is related to the rotation angle of the rotating rod 16. In this way, after all the shell samples on the feeding plate 6 have left, the locking block 41 will just separate from the locking groove 42, and then the mounting plate 5 will spring up. This allows the staff to more quickly and intuitively determine whether there are still shell samples on the mounting plate 5.

[0055] As a further aspect of the present invention, a method for using a device for measuring the carbon content of shellfish is provided, the specific steps of which are as follows:

[0056] Step 1: The staff places the shell sample to be tested on the feeding plate 6. Each feeding plate 6 can hold a maximum of one shell sample. Then, the mounting plate 5 is pressed vertically downward into the vertical groove 7 opened in the machine cover 3. When the locking block 41 is locked into the locking groove 42 opened on the left surface of the mounting plate 5, the mounting plate 5 is installed.

[0057] Step 2: Next, the drive assembly will drive the rotating frame 13 to rotate 90 degrees and then stop. The transfer plate 14 will rotate to the bottom of the bottom feeding plate 6. At the same time, the drive assembly will drive the rotating rod 16 to rotate one revolution. Under the rotation of the cam, the feeding plate 6 will open from bottom to top. The shell samples on the feeding plate 6 will move to the next feeding plate 6, while the shell samples on the bottom feeding plate 6 will fall onto the transfer plate 14.

[0058] Step 3: The drive assembly drives the rotating frame 13 to rotate 270 degrees again. The transfer plate 14 will rotate back to the initial position from below the discharge plate 6. The transfer plate 14 will pass over the sample chamber 4. When the transfer plate 14 rotates to the top of the sample chamber 4, the blocking block 25 will block the rotating plate 17. The rotating frame 13 will continue to move and separate the two transfer plates 14. Then the shell samples on the transfer plates 14 will fall onto the sample chamber 4.

[0059] Step 4: The machine body 1 tests the seashell samples on the sample chamber 4;

[0060] Step 5: When the drive assembly drives the rotating frame 13 to rotate again to transport the shell sample to the sample chamber 4, the discharge ring 28 located behind the rotating frame 13 will take away the shell sample located on the sample chamber 4 and then discharge it from the discharge port 29.
