Description

Technical Field

[0001] This utility model relates to the technical field of sample extraction devices, and in particular to a sample extraction device for shrimp meat detection. Background Technology

[0002] In the field of food testing, quality inspection of aquatic products such as shrimp is crucial, and sample extraction is a key starting point in the testing process. Accurate and efficient sample extraction provides representative and pure samples for subsequent testing and analysis, thereby ensuring the reliability of test results. Sample extraction aims to obtain information from shrimp samples that truly reflects their internal components and the presence of contaminants or pathogens, enabling in-depth analysis using various testing methods. However, there are shortcomings in the traditional sample extraction methods used in practice.

[0003] When cutting and sampling shrimp, manual operation is mostly relied upon, which is not only inefficient but also makes it difficult to ensure the consistency and accuracy of each cut. For example, in batch testing, manual cutting is slow, consumes a lot of time and manpower, and the differences in the techniques of different operators can lead to deviations in the size and location of the samples, affecting the accuracy and comparability of the test results. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a sample extraction device for shrimp meat detection, which overcomes the shortcomings of the prior art and effectively solves the problems of low efficiency and difficulty in ensuring the consistency and accuracy of each cut by relying on manual operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sample extraction device for shrimp detection includes a fixed cylinder. A fixed tube is inserted and fixed to one side of the outer wall of the fixed cylinder, and a suction pump is inserted and fixed to one side of the outer wall of the fixed cylinder below the fixed tube. A limit block is welded and fixed to the inner wall of the fixed cylinder, and a hexagonal rod is inserted and movable at the top of the fixed cylinder and the top of the limit block. A telescopic spring is movably sleeved on the rod wall of the hexagonal rod. A pressing block is welded and fixed to the top of the hexagonal rod, and a ventilation tube is welded and fixed to the bottom of the hexagonal rod. A filter ring is screwed to the bottom of the fixed cylinder, and a fixed shell is sleeved and fixed to the bottom of the outer wall of the fixed cylinder. An extraction mechanism is rotatably connected to the bottom of the fixed cylinder and the fixed shell. The extraction mechanism includes a rotating tube, a connecting shell welded and fixed to the bottom of the rotating tube, a cutting component inserted into the top of the connecting shell, and a servo motor installed and fixed to the top of the fixed shell. The cutting component includes a mounting ring, an annular cutter welded and fixed to the bottom of the mounting ring, and a connecting rod welded and fixed to the top of the mounting ring at equal intervals along the ring.

[0006] Preferably, the telescopic spring is located between the top of the fixed cylinder and the bottom of the pressing block, and a pressing switch is fixedly installed on the top of the pressing block. The suction pump and the servo motor are both electrically connected to the pressing switch.

[0007] Preferably, the hexagonal rod has a collar sleeved and fixed to its wall, and the collar is located between the top of the limiting block and the top inner wall of the fixing cylinder.

[0008] Preferably, the ventilation duct has an opening facing downwards, and a ventilation hole is provided on one side of the outer wall of the ventilation duct. The fixed pipe and the suction pump are connected to the ventilation hole.

[0009] Preferably, the bottom of the outer wall of the fixed cylinder is rotatably connected to the inner wall of the rotating tube, and the bottom of the inner wall of the fixed shell is rotatably connected to the outer wall of the rotating tube. The output shaft of the servo motor and the outer wall of the rotating tube are both fitted with meshing gears.

[0010] Preferably, the top of the connecting shell has a through hole that matches the inner diameter of the rotating tube, and the top of the connecting shell has slots that are evenly distributed along the circumference. The slots and the connecting rod form an interference fit, and the outer diameter of the annular cutter matches the inner diameter of the connecting shell.

[0011] The beneficial effects of this utility model are as follows: To improve cutting efficiency and accuracy, a servo motor drives the rotating tube, which in turn drives the annular cutter connected to the bottom of the shell to rotate at high speed. Compared to manual cutting, this allows for faster and more uniform cutting of shrimp, significantly improving cutting efficiency. Furthermore, due to the structural design of the cutting assembly, the position and cutting path of the annular cutter are relatively fixed, ensuring consistency in each cut and improving the accuracy of the sample taken. This contributes to the accuracy and reliability of subsequent testing results. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0015] Reference Figure 1-4 A sample extraction device for shrimp detection includes a fixed cylinder 1, a fixed tube 2 inserted and fixed to one side of the outer wall of the fixed cylinder 1, a suction pump 3 inserted and fixed to one side of the outer wall of the fixed cylinder 1 below the fixed tube 2, a limit block 4 welded and fixed to the inner wall of the fixed cylinder 1, a movable hexagonal rod 5 inserted and fixed to the top of the fixed cylinder 1 and the top of the limit block 4, a telescopic spring 6 movably sleeved on the rod wall of the hexagonal rod 5, a pressing block 7 welded and fixed to the top of the hexagonal rod 5, a ventilation tube 9 welded and fixed to the bottom of the hexagonal rod 5, and a filter ring 1 screwed to the bottom of the fixed cylinder 1. 0. A fixed shell 11 is fitted and fixed to the bottom of the outer wall of the fixed cylinder 1. The bottom ends of the fixed cylinder 1 and the fixed shell 11 are rotatably connected to the extraction mechanism 12. The extraction mechanism 12 includes a rotating tube 13, a connecting shell 14 welded and fixed to the bottom of the rotating tube 13, a cutting assembly 15 inserted into the top of the connecting shell 14, and a servo motor 19 installed and fixed to the top of the fixed shell 11. The cutting assembly 15 includes a mounting ring 16, an annular cutter 17 welded and fixed to the bottom of the mounting ring 16, and a connecting rod 18 welded and fixed to the top of the mounting ring 16 at equal intervals along the ring. The telescopic spring 6 is located between the top of the fixed cylinder 1 and the bottom of the pressing block 7, which serves as the operation trigger. When the device needs to be started for sample extraction, the operator presses down on the pressing block 7. A press switch is fixedly installed on the top of the pressing block 7, which is the key trigger point for the entire device's circuit control. Both the suction pump 3 and the servo motor 19 are electrically connected to the press switch, so when the pressing block 7 is pressed, the press switch closes, the circuit is connected, and the suction pump 3 and the servo motor 19 start working simultaneously. After the suction pump 3 starts working, it creates a negative pressure in the ventilation cylinder 9, providing power for subsequent sample extraction; after the servo motor 19 starts, it drives the gear on its output shaft to rotate, which in turn meshes with the gear fixed to the outer wall of the rotating tube 13, driving the rotating tube 13 to start rotating. A collar 8 is fixedly fitted onto the wall of the hexagonal rod 5. The collar 8 is located between the top of the limiting block 4 and the top inner wall of the fixed cylinder 1. The main function of the collar 8 is to limit and guide the hexagonal rod 5. Due to the special shape of the hexagonal rod 5, it can only move vertically within the fixed cylinder 1. The collar 8 further ensures the uniformity of the movement path of the hexagonal rod 5 during movement, preventing deviation of its movement path. When the pressing block 7 is pressed down, the hexagonal rod 5 moves downward under the action of the pressing block 7. The collar 8 moves downward along with the hexagonal rod 5. Under the restriction of the limiting block 4, it ensures that the hexagonal rod 5 descends stably along a fixed path, thereby ensuring that the ventilation cylinder 9 can accurately reach the position where the sample needs to be extracted. The ventilation cylinder 9 has its opening facing downwards, and a ventilation hole is provided on one side of its outer wall. Both the fixed pipe 2 and the suction pump 3 are connected to the ventilation hole. When the suction pump 3 starts, the generated negative pressure is transmitted to the ventilation hole of the ventilation cylinder 9. Because the ventilation cylinder 9 has its opening facing downwards, when it approaches the cut shrimp sample, the sample is sucked into the connecting shell 14 under the action of negative pressure. The design of the ventilation hole position ensures that the negative pressure can effectively act inside the ventilation cylinder 9, allowing the sample to be smoothly sucked in, while also avoiding excessive interference from outside air, ensuring the efficiency and purity of sample suction. When the ventilation hole is connected to the fixed pipe 2, it ensures that the pressure inside and outside is consistent, facilitating the removal of the sample from the connecting shell 14. The bottom outer wall of the fixed cylinder 1 is rotatably connected to the inner wall of the rotating tube 13, and the bottom inner wall of the fixed shell 11 is rotatably connected to the outer wall of the rotating tube 13. This double rotatable connection allows the rotating tube 13 to rotate stably between the fixed cylinder 1 and the fixed shell 11. The output shaft of the servo motor 19 and the outer wall of the rotating tube 13 are both fitted with meshing gears. When the servo motor 19 starts, its output shaft drives its own gears to rotate, and through the meshing transmission between the gears, it drives the rotating tube 13 to start rotating. The rotation of the rotating tube 13 drives the connecting shell 14 and the cutting assembly 15 to rotate together, thereby realizing the cutting operation of the shrimp. This structural design ensures the stability and smooth rotation of the cutting assembly 15 during operation. The top of the connecting shell 14 has a through hole that matches the inner diameter of the rotating tube 13. The rotating tube 13 can be tightly connected to the connecting shell 14 through this through hole, ensuring that the rotating tube 13 can stably drive the connecting shell 14 to rotate together when rotating. The top of the connecting shell 14 has equally spaced slots arranged in a ring shape, and the slots form an interference fit with the connecting rod 18. When the cutting component 15 needs to be installed, the connecting rod 18 is inserted into the slot. Due to the interference fit, the stability of the cutting component 15 within the connecting shell 14 is ensured, preventing loosening or displacement during rotation. The outer diameter of the annular cutter 17 matches the inner diameter of the connecting shell 14. This allows for maximum utilization of the space in the connecting shell 14 when the annular cutter 17 rotates to cut shrimp, ensuring cutting effect and efficiency.

[0016] Working principle: When sample extraction is required, the operator presses down on the pressing block 7. A pressure switch is installed on the top of the pressing block 7. As the pressing block 7 is pressed, the pressure switch closes, and the suction pump 3 and servo motor 19, electrically connected to the pressure switch, start simultaneously. After the servo motor 19 starts, the gear fixed to its output shaft begins to rotate. Since this gear meshes with the gear fixed to the outer wall of the rotating tube 13, it drives the rotating tube 13 to rotate. The rotation of the rotating tube 13, in turn, drives the connecting shell 14 welded to its bottom and the cutting assembly 15 installed inside the connecting shell 14 to rotate together. The annular cutter 17 in the cutting assembly 15 cuts the shrimp below during rotation. At the same time, the downward pressure of the pressing block 7 causes the hexagonal rod 5, which is welded and fixed to it, to move downward. A collar 8 is fixedly fitted onto the wall of the hexagonal rod 5. The collar 8 moves between the top of the limiting block 4 and the inner top wall of the fixed cylinder 1, ensuring the stability of the ventilation cylinder 9's movement path within the fixed cylinder 1. Therefore, the ventilation cylinder 9 moves downward along with the hexagonal rod 5, gradually approaching the shrimp being cut. After the suction pump 3 is started, a negative pressure is formed between the suction pump 3 and the ventilation tube 9. Since the opening of the ventilation tube 9 faces downward and a ventilation hole is provided on one side of the outer wall, the suction pump 3 and the ventilation hole are connected and cooperated. Therefore, when the ventilation tube 9 is close to the cut shrimp, the cut shrimp sample is sucked into the connecting shell 14 under the action of negative pressure. During the process of the sample being drawn into the connecting shell 14, the filter ring 10 screwed to the bottom of the fixed cylinder 1 plays a role. The filter ring 10 can block the drawn-in sample, preventing shrimp from entering the interior of the fixed cylinder 1, thus ensuring the purity of the environment inside the fixed cylinder 1. After sample extraction is complete, releasing the pressing block 7 causes the telescopic spring 6 to push the pressing block 7 upwards, resetting it. The hexagonal rod 5 and the ventilation tube 9 also move upwards back to their initial positions. Simultaneously, the servo motor 19 and the suction pump 3 stop operating. The ventilation holes on the ventilation tube 9 are connected to the fixed tube 2, ensuring normal pressure within the fixed tube 1 compared to the outside environment. At this point, the sample can fall downwards from the connecting shell 14, allowing for further analysis and testing of the extracted sample. Through the coordinated operation of its components, the entire device achieves efficient and accurate extraction of shrimp samples, providing a reliable sample source for shrimp testing.
