Description

Technical Field

[0001] This invention relates to the field of food sampling device technology, specifically to a multi-point food sampling device and sampling method. Background Technology

[0002] As people pay more and more attention to food safety, it is essential to take regular and fixed-point samples of food materials during the food production process to test the composition, trace elements, pesticide residues and impurities of the materials.

[0003] Existing multi-point sampling devices typically involve repeatedly sampling with the same device or resampling after moving the device, simultaneously sampling from multiple locations or even materials of different textures. For example, in food production, the upper layer of material is fluid while the lower layer has poor flowability. Sampling materials at different depths requires changing different sampling equipment, which is inconvenient.

[0004] For example, Chinese Patent Publication No. CN216284344U discloses a multi-point sampling device for food testing, comprising a chassis. A first motor is bolted to the top of the left side of the chassis cavity. The output shaft of the first motor is bolted to a first lead screw. The right side of the first lead screw is rotatably connected to the top of the right side of the chassis cavity via a bearing. Through the cooperation of the first motor, the first lead screw, the movable threaded sleeve, and the first cylinder, manual sampling is avoided, reducing the labor intensity of the user. Through the cooperation of a second motor, a rotating shaft, a driving gear, a driven gear, a second lead screw, an extended threaded sleeve, and a sampling frame, the user can easily move the sampling frame out of the sampling box to sample the food. In this application, the sampling depth can be changed by operating the first cylinder, but the device can only sample from a single location at a time, which is inconvenient to use.

[0005] Therefore, this application provides a food multi-point sampling device and sampling method to solve the problem that the sampling devices in the prior art can only sample materials from a single location or with a single texture, resulting in low efficiency. Summary of the Invention

[0006] To address the above problems, the present invention provides a food multi-point sampling device and sampling method.

[0007] The technical solution adopted by the present invention to solve its technical problem is: a multi-point sampling device for food, including an operating rod for inserting into the food for sampling, a plurality of sampling components rotatably connected to the side of the operating rod, the sampling components being rotatably open away from the operating rod, the sampling components being able to sample liquids or non-flowing materials, the sampling components having a guide blade in the length direction, an openable and closable solid sampling port on the side opposite to the guide blade, and an openable and closable liquid sampling port at the outer end of the sampling components; The adjustment assembly includes a first telescopic rod and a connecting rod. The outer end of the connecting rod is connected to the sampling assembly, and the other end of the connecting rod is connected to the movable part of the first telescopic rod. The connecting rod is a flexible rod.

[0008] As an optimization, the sampling assembly includes a connecting seat and a sampling tube. The connecting seat is rotatably connected to the side of the operating lever. A drive motor is installed inside the connecting seat, and the output shaft of the drive motor is connected to the axis of the sampling tube.

[0009] As an optimization, a second telescopic rod is provided inside the sampling tube, and a sealing piston is connected to the extended end of the second telescopic rod; A sealing plug is provided on the inner side of the liquid sampling port, and the inner diameter of the sampling tube is larger than the inner diameter of the liquid sampling port.

[0010] As an optimization, a sealing plate is provided on the inner side of the solid sampling port, and an electromagnet is provided on the side of the sealing piston opposite to the sealing plate. When the electromagnet is energized, it can be magnetically connected to the sealing plate.

[0011] As an optimization, the operating rod is provided with a first receiving cavity and a second receiving cavity. The fixed part of the first telescopic rod is located inside the first receiving cavity. A connecting hole is provided between the first receiving cavity and the second receiving cavity. The extended part of the first telescopic rod passes through the first receiving cavity and then through the connecting hole to extend into the second receiving cavity.

[0012] As an optimization, a plurality of the sampling components are arranged in an array along the circumferential direction of the operating lever, forming a first sampling part and a second sampling part on the outside of the operating lever, the first sampling part being located at the upper part of the operating lever and the second sampling part being located at the lower part of the operating lever; A first connecting plate is provided on the upper part of the extended portion of the first telescopic rod, and the sampling component of the first sampling part is connected to the first connecting plate through the connecting rod.

[0013] As an optimization, a second connecting plate is provided inside the second receiving cavity, and a drive rod is connected to the second connecting plate. A connecting rack is provided at the lower part of the first telescopic rod, and a connecting gear is provided between the connecting rack and the drive rod. When the first telescopic rod extends or retracts, the drive rod is moved through the connecting gear. The sampling component of the second sampling section is connected to the second connecting plate via a connecting rod.

[0014] As an optimization, the outer recess of the operating lever forms a receiving groove for accommodating the sampling component; The first sampling section rotates upward to open, and the second sampling section rotates downward to open.

[0015] The sampling method, including the food multi-point sampling device described in any one of the above, specifically includes the following steps: The operating lever is inserted into the food material, and the first telescopic rod is rotated to drive the first sampling part and the second sampling part to rotate outward and open. When sampling liquid materials through the first sampling section and / or the second sampling section, the second telescopic rod operates to open the liquid sampling port for sampling. Solid materials are sampled through the first sampling section and / or the second sampling section. The electromagnet is energized, and the second telescopic rod moves the sealing plate to open the solid sampling port for sampling.

[0016] As an optimization, the first sampling unit and the second sampling unit can simultaneously perform sampling operations on materials of the same or different textures.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-5 As shown, a multi-point sampling device for food includes an operating rod 1 for inserting into the food to take samples. Several sampling components are rotatably connected to the side of the operating rod 1. The sampling components can rotate and open away from the operating rod 1. The sampling components can sample liquids or non-flowing materials. The sampling components are provided with a guide blade 2 along their length. An openable solid sampling port 3 is provided on the side opposite to the guide blade 2. An openable liquid sampling port 4 is provided at the outer end of the sampling components. The adjustment assembly includes a first telescopic rod 5 and a connecting rod 6. The outer end of the connecting rod 6 is connected to the sampling assembly, and the other end of the connecting rod 6 is connected to the movable part of the first telescopic rod 5. The connecting rod 6 is a flexible rod.

[0026] according to Figure 1 It can be seen that when the sampling component located on the upper side is rotated upward, the material at the top can be pushed away by the guide blade 2, making it easier for the sampling component to be released outward. When the sampling component located on the lower side is rotated downward, the guide blade 2 is located on the lower side of the sampling component, while the sampling component can be rotated so that the guide blade 2 is located on the upper side of the sampling tube 8; in actual use, the sampling component can be rotated according to the sampling direction.

[0027] The upper end of the operating lever 1 is connected to a handle, which can be any shape that is easy to grip. The operating lever 1 contains a power supply and controller, and correspondingly, a control button is located on the handle. The lower end of the operating lever 1 is a pointed tip, making it easy to insert the operating lever 1 into the material.

[0028] like Figure 3 As shown, the sampling assembly includes a connecting seat 7 and a sampling tube 8. The connecting seat 7 is rotatably connected to the side of the operating rod 1. A drive motor 9 is installed inside the connecting seat 7, and the output shaft of the drive motor 9 is connected to the axis of the sampling tube 8.

[0029] The outer end of the sampling tube 8 is open, while the end of the sampling tube 8 connected to the connecting seat 7 is closed. The sampling tube 8 and the connecting seat 7 can be cylindrical. When the sampling assembly extends outward, the connecting rod 6 is arc-shaped, and the connecting rod 6 can support the sampling tube 8, keeping the sampling tube 8 perpendicular to the operating rod 1.

[0030] like Figure 3 and Figure 4 As shown, a second telescopic rod 10 is provided inside the sampling tube 8, and a sealing piston 11 is connected to the extended end of the second telescopic rod 10; A sealing plug 21 is provided on the inner side of the liquid sampling port 4, and the inner diameter of the sampling tube 8 is larger than the inner diameter of the liquid sampling port 4.

[0031] The sampling tube 8 has a guide block on its inner wall and a guide rod on the inner side of the sealing plug 21. When the second telescopic rod 10 retracts, a negative pressure chamber is formed between the sealing piston 11 and the sealing plug 21. Under pressure, the external liquid can push the sealing plug 21 into the sampling tube 8, thus achieving liquid material sampling. During sampling, the guide block can limit the sealing plug 21, preventing it from moving further into the sampling tube 8. When the second telescopic rod 10 can no longer retract, it quickly extends outward a certain distance, causing the sealing plug 21 to return to the liquid sampling port 4 under pressure, sealing the liquid sampling port 4.

[0032] like Figure 4 As shown, a sealing plate 12 is provided on the inner side of the solid sampling port 3, and an electromagnet 13 is provided on the side of the sealing piston 11 opposite to the sealing plate 12. When the electromagnet 13 is energized, the electromagnet 13 can be magnetically connected to the sealing plate 12.

[0033] When solid material sampling is required, the electromagnet 13 is energized, and the second telescopic rod 10 drives the sealing plate 12 to move away from the solid sampling port 3.

[0034] like Figure 3 and Figure 5As shown, the operating lever 1 has a first receiving cavity 14 and a second receiving cavity 15 inside. The fixed part of the first telescopic rod 5 is located inside the first receiving cavity 14. A connecting hole is provided between the first receiving cavity 14 and the second receiving cavity 15. The extended part of the first telescopic rod 5 passes through the first receiving cavity 14 and then through the connecting hole to extend into the second receiving cavity 15.

[0035] The first receiving cavity 14, the second receiving cavity 15, and the connecting hole are all coaxially arranged with the operating rod 1.

[0036] like Figure 1 and Figure 3 As shown, a plurality of the sampling components are arranged in an array along the circumferential direction of the operating lever 1, forming a first sampling part and a second sampling part on the outside of the operating lever 1. The first sampling part is located at the upper part of the operating lever 1, and the second sampling part is located at the lower part of the operating lever 1. A first connecting plate 16 is provided on the upper part of the extended portion of the first telescopic rod 5, and the sampling component of the first sampling part is connected to the first connecting plate 16 through the connecting rod 6.

[0037] The first connecting plate 16 is located inside the first receiving cavity 14. The first connecting plate 16 can move up and down inside the first receiving cavity 14. When the first connecting plate 16 moves to the bottom of the first receiving cavity 14, the connecting rod 6 can push the first sampling part to a horizontal state.

[0038] like Figure 3 and Figure 5 As shown, a second connecting plate 17 is provided inside the second receiving cavity 15. The second connecting plate 17 is connected to a drive rod 19. A connecting rack is provided at the lower part of the first telescopic rod 5. A connecting gear 18 is provided between the connecting rack and the drive rod 19. When the first telescopic rod 5 extends or retracts, the drive rod 19 is moved by the connecting gear 18. The sampling component of the second sampling section is connected to the second connecting plate 17 via the connecting rod 6.

[0039] Several second connecting plates 17 are arranged in an array along the circumference of the first telescopic rod 5. A rack is also provided along the length of the drive rod 19. The drive rod 19 and the connecting rack are arranged opposite each other on both sides of the connecting gear 18. When the first telescopic rod 5 extends, it drives the drive rod 19 to extend upward, which in turn pushes the second sampling part outward through the connecting rod 6.

[0040] like Figure 1 As shown, the outer recess of the operating lever 1 forms a receiving groove 20, which is used to receive the sampling component; The first sampling section rotates upward to open, and the second sampling section rotates downward to open.

[0041] The sampling method, including the food multi-point sampling device described in any one of the above, specifically includes the following steps: Before sampling, the sampling component is retracted inside the receiving groove 20, and the length direction of the sampling component is parallel to the length direction of the operating rod 1; The staff member holds the handle and inserts the operating lever 1 into the food material to a specified depth; The first and second sampling sections are controlled according to sampling requirements; When solid material sampling is required, the first telescopic rod 5 is operated to drive the sampling component to rotate outward a certain distance, and the driving motor 9 drives the sampling tube 8 to rotate, so that the solid sampling port 3 opens in a direction away from the operating rod 1. Solid materials are sampled through the first sampling section and / or the second sampling section. The electromagnet 13 is energized, and the second telescopic rod 10 drives the sealing plate 12 to move, thereby opening the solid sampling port 3. When the electromagnet 13 is de-energized, the second telescopic rod 10 drives the sealing piston 11 to continue moving to the end of the sealing plate 12 away from the solid sampling port 3, increasing the sampling space inside the sampling tube 8. When the electromagnet 13 is energized, the sealing piston 11 and the sealing plate 12 are reconnected, and sampling begins. As the first telescopic rod 5 continues to operate, it drives the first sampling part and the second sampling part to rotate outward and open. When the sampling tube 8 rotates open, the solid material is pressed into the sampling tube 8 to achieve sampling of the solid material. When the sampling tube 8 is rotated to be perpendicular to the operating rod 1, the sampling of solid material is completed. The second telescopic rod 10 extends, and the sealing piston 11 drives the sealing plate 12 to close the solid sampling port 3.

[0042] When sampling liquid materials through the first sampling section and / or the second sampling section, the first telescopic rod 5 is operated to position the guide blade 2 on the side away from the operating rod 1, and the first telescopic rod 5 drives the first sampling section and the second sampling section to rotate outward and open. When liquid material sampling is required, the electromagnet 13 is de-energized, and the solid sampling port 3 is sealed by the sealing plate 12. The second telescopic rod 10 is shortened, so that a negative pressure space is formed between the sealing piston 11 and the sealing plug 21. Under the pressure, the external liquid material pushes the sealing plug 21 into the sampling tube 8. The second telescopic rod 10 is shortened again, so that the liquid material enters the sampling tube 8. After the liquid material is sampled, the second telescopic rod 10 is quickly extended a certain distance, causing the liquid material to push the sealing plug 21 back into the liquid sampling port 4, thus sealing the end of the sampling tube 8.

[0043] The first and second sampling units can simultaneously sample liquid or solid materials at different heights, or they can sample fixed or liquid materials separately without affecting each other.
