Description

Technical Field

[0001] This utility model relates to the field of frozen meat testing, and in particular to a frozen meat sampling device. Background Technology

[0002] Volatile basic nitrogen (TVB-N) refers to the total amount of volatile amines (such as trimethylamine, dimethylamine, histamine, etc.) and alkaline nitrogenous substances such as ammonia produced by the decomposition of proteins during the spoilage process of animal foods due to bacterial action. It is one of the important indicators for evaluating the freshness of animal foods such as meat and fish. The first step in testing is sampling. Take a representative sample, chop it up, and then homogenize it with a tissue homogenizer. If it is a frozen sample, it needs to be thawed and mixed first.

[0003] In the prior art, Chinese utility model patent with authorization announcement number CN 208333915 U discloses a frozen meat sampling device, including a main body. The bottom of the main body has an opening, and a fixed cylinder is fixedly installed at the opening. The fixed cylinder is located inside the main body. The bottom inner wall of the fixed cylinder has a sample collection chamber. A telescopic cylinder is fixedly connected to the fixed cylinder through a sliding telescopic bearing. A cylindrical blade is fixedly connected to the top inner wall of the telescopic cylinder through a buckle. A power gear is fixedly fitted on the telescopic cylinder, and the power gear meshes with a transmission gear. A motor is fixedly installed on the outer wall of the main body. The power of the motor reaches the telescopic cylinder through the transmission gear and the power gear, driving the blade to rotate. The cut frozen meat passes through the cylindrical blade, the telescopic cylinder, and the fixed cylinder in sequence and falls into the sample collection chamber. The motor is turned off, and the sampling is completed in one go. This method of sampling at each sampling point reduces the workload of technicians.

[0004] However, when using the above technical solutions, on the one hand, frozen meat has a certain degree of hardness, especially the muscle part, whose surface can reach the hardness of blocky hard plastic. It is necessary to apply a lot of pressure manually at the beginning of sampling in order to allow the cylindrical blade to enter the frozen meat for sampling. This makes the use of the above devices still relatively laborious. On the other hand, the meat sample needs to pass through the cylindrical blade, the telescopic cylinder, and the fixed cylinder before falling into the sample collection chamber. The distance that the meat sample has to travel is relatively long. If the frozen meat is relatively thin, it cannot reach the sample collection chamber. Other auxiliary placement is required to remove the cut sample, which makes it inconvenient to use. Utility Model Content

[0005] To address the technical problem of laborious sampling of frozen meat in existing technologies, this utility model provides a frozen meat sampling device that can reduce the labor intensity of sampling and facilitate the removal of meat samples.

[0006] To solve the above problems, the present invention adopts a frozen meat sampling device, including a support plate with a horizontal support bar above it, and further including: a rotating screw, which is vertically mounted on the support bar and passes through the support bar and is axially movable; a heating plate, which is threadedly connected to the lower end of the rotating screw and has a resistance wire for defrosting frozen meat; and a sampling blade, which is threadedly connected to the rotating screw and has a nut that abuts against the upper surface of the sampling blade. The sampling blade has a cylindrical structure and uniformly arranged blade teeth on its lower end face.

[0007] In this design, by screwing a heating plate and a sampling knife onto the lower part of the rotating screw, the surface of the frozen meat sampling location can be heated first when the frozen meat is relatively hard, reducing the surface hardness and making it easier for the sampling knife to penetrate. This greatly avoids the need for the operator to apply a lot of pressure at the beginning to make the sampling knife penetrate, reducing labor intensity. In addition, the sampling knife also acts as a container. After sampling, the meat sample can be removed by rotating the sampling knife upwards under the pushing action of the rotating screw, making it convenient to use.

[0008] Preferably, the heating plate includes a detachable connecting cover and a plate body. The connecting cover is provided with a mounting screw hole, which can be threadedly connected to the rotating screw. The plate body is provided with a power supply and the resistance wire. The resistance wire and the power supply are electrically connected through a switch. A heat-conducting layer is provided at the bottom of the plate body. The diameter of the heat-conducting layer is not less than the diameter of the sampling blade.

[0009] In this preferred embodiment, heat exchange can be accelerated by setting a heat-conducting layer.

[0010] Preferably, the disk body is provided with a receiving cavity, and a partition is provided in the receiving cavity to divide the receiving cavity into an upper part and a lower part. The partition is provided with wiring holes. The power supply is located in the upper part, the resistance wire is located in the lower part, and the heat-conducting layer is connected to the partition through studs and is located below the resistance wire.

[0011] In this preferred embodiment, the partition prevents the power supply from being affected by the resistance wire, thereby affecting the lifespan of the power supply.

[0012] Preferably, the lower end of the rotating screw is provided with a sampling cone, the cone surface of which is provided with threads, and the sampling cone can extend into the interior of the disc or the cavity of the sampling knife, and the sampling cone is used to pierce frozen meat.

[0013] In this preferred embodiment, by providing a threaded sampling cone at the lower part of the rotating screw, on the one hand, the sampling cone can more easily enter the frozen meat during sampling, further reducing the penetration resistance; on the other hand, the sampling cone can remain connected to the cut sample until the operator rotates it off, preventing the sample from falling off during sampling.

[0014] Preferably, the tip of the sampling cone can extend beyond the sampling blade, and the tip of the sampling cone is unthreaded.

[0015] In this preferred embodiment, by setting the sampling cone to extend beyond the sampling blade, it is convenient for the operator to test the surface hardness of frozen meat at the beginning. The operator can judge whether heating is required based on the marks left by the sampling cone on the surface of the frozen meat, thus avoiding misjudgment caused by the operator's judgment based on feeling, which would affect the sampling efficiency.

[0016] Preferably, the lower part of the blade has a conical structure, and the blade is also provided with a guide arc surface. The projection of the guide arc surface on the lower end face of the sampling blade is tangent to the outer edge of the sampling blade, and a cutting edge is provided on the side of the guide arc surface near the outer circumference of the sampling blade.

[0017] In this preferred embodiment, the guide arc surface facilitates the cutting of frozen meat by the blade when the sampling knife rotates, reducing cutting resistance.

[0018] Preferably, a limiting plate is rotatably provided at the upper end of the rotating screw, and the limiting plate can abut against the upper surface of the supporting crossbar.

[0019] In this preferred embodiment, by setting a limiting plate, the distance between the limiting plate and the support crossbar can be adjusted according to the thickness of the frozen meat, so as to avoid the sampling knife damaging the support plate under the frozen meat.

[0020] Preferably, a spring is provided between the rotating screw and the turntable on the lower surface of the supporting crossbar, the turntable is rotatably mounted on the lower surface of the supporting crossbar, and a guide hole is vertically provided on the supporting crossbar, through which the rotating screw passes.

[0021] In this preferred embodiment, by setting a spring, it is possible to ensure that when different operators turn the screw to pierce the frozen meat at the beginning of the meat sample hardness test, the operator can easily ensure that the same force is applied when different operators turn the screw. This avoids the influence of different operator forces on the judgment of hardness, and makes the hardness judgment more objective.

[0022] Preferably, the support plate is provided with a limit fence, and the inner wall of the limit fence is provided with a support boss. Multiple adjustment slots are provided on both the long side and the wide side of the limit fence. The opening of the adjustment slots faces upward. A positioning plate is inserted into the limit fence through the adjustment slots. Multiple adjustment slots are provided on the positioning plate. The opening of the adjustment slots faces upward. A positioning plate is also inserted into the limit fence through the adjustment slots and the adjustment slots. The positioning plate is perpendicular to the positioning plate.

[0023] In this preferred embodiment, by setting a limiting fence, positioning plate one, and positioning plate two, the size of the limiting area can be adjusted according to the size of the frozen meat, preventing the frozen meat from rotating during sampling and improving the flexibility of the device.

[0024] Preferably, the support plate is also provided with two support vertical rods opposite each other. The support vertical rods are provided with a plurality of adjustment holes along their height direction. Adjustment bolts are inserted through the adjustment holes and can be screwed to the end of the support horizontal rod.

[0025] In this preferred embodiment, the height of the support crossbar can be adjusted by setting adjustment holes, thereby adjusting the relative distance between the lower end of the rotating screw and the frozen meat. This avoids the frozen meat being too thick and interfering with the sampling knife, making it difficult to install into the limiting area. It is suitable for frozen meat of various thicknesses.

[0026] As can be seen from the above technical solutions, the advantages of this utility model are as follows: By screwing a heating plate and a sampling knife separately to the lower part of the rotating screw, when the frozen meat is relatively hard, the surface of the sampling location of the frozen meat can be heated first using the heating plate to reduce the surface hardness, making it easier for the sampling knife to penetrate. This greatly avoids the need for the operator to apply a large amount of pressure to penetrate the sampling knife at the beginning, reducing labor intensity. In addition, the sampling knife acts as a container. After sampling, the meat sample can be removed by rotating the sampling knife upwards under the pushing action of the rotating screw, making it convenient to use. The heat-conducting layer can accelerate heat exchange. The partition plate avoids the power supply being affected by the resistance wire, thus affecting the service life of the power supply. By setting a threaded sampling cone at the lower part of the rotating screw, on the one hand, the sampling cone can easily enter the frozen meat during sampling, further reducing the penetration resistance. On the other hand, the sampling cone can remain connected to the cut sample until the operator rotates it to remove it, preventing the sample from falling out during sampling. By setting the sampling cone to extend beyond the sampling knife, it is convenient for the operator to test the surface of the frozen meat at the beginning. The hardness testing system uses the marks left by the sampling cone on the frozen meat surface to determine whether heating is necessary, avoiding misjudgments caused by operator intuition and affecting sampling efficiency. The guide arc surface facilitates the cutting of the frozen meat by the sampling blade during rotation, reducing cutting resistance. The limiting plate allows adjustment of the distance between the limiting plate and the support crossbar according to the thickness of the frozen meat, preventing damage to the support plate below the frozen meat by the sampling blade. The spring design ensures that different operators apply the same force to pierce the frozen meat when initially testing its hardness, preventing variations in operator strength from affecting hardness judgment and making the assessment more objective. The limiting fence, positioning plate one, and positioning plate two allow adjustment of the limiting area size according to the size of the frozen meat, preventing rotation during sampling and improving the device's flexibility. The adjustment hole allows adjustment of the height of the support crossbar, thereby adjusting the relative distance between the lower end of the rotating screw and the frozen meat, preventing interference between the frozen meat and the sampling blade due to excessive thickness, making it suitable for frozen meat of various thicknesses.

Detailed Implementation

[0035] To make the objectives, features, and advantages of this utility model / invention more apparent and understandable, the technical solutions of this utility model / invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model / invention, and not all embodiments. Based on the embodiments in this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0036] like Figure 1 and Figure 2As shown in the figure, this specific embodiment provides a frozen meat sampling device, including a support plate 1, a support crossbar 3, a rotating screw 11, a heating plate 14, and a sampling knife 10. The support crossbar 3 is horizontally arranged above the support plate 1, and the rotating screw 11 is vertically arranged on the support crossbar 3. A guide hole is vertically arranged on the support crossbar 3, through which the rotating screw 11 passes and is axially movable. The heating plate 14 is threadedly connected to the lower end of the rotating screw 11, and the heating plate 14 is equipped with a resistance wire 1403 for defrosting frozen meat. The sampling knife 10 is threadedly connected to the rotating screw 11, and the rotating screw 11... A nut 20 is provided, the lower surface of which can abut against the sampling knife 10. The sampling knife 10 has a cylindrical structure, and the lower end face of the sampling knife 10 is evenly provided with blade teeth 12. The sampling knife 10 can move along the rotating screw 11 in the direction of the supporting crossbar 3. When sampling, for frozen meat with high hardness that is difficult for the sampling knife 10 to sample, the heating plate 14 can be installed first to heat the meat sample. After heating for a set time, the heating plate 14 can be removed and the sampling knife 10 can be installed. The sampling is performed by rotating the rotating screw 11. After sampling, the meat sample is located inside the sampling knife 10. By rotating the sampling knife 10 upward, the meat sample is pushed out of the sampling knife 10 by the rotating screw 11.

[0037] In this specific embodiment, by screwing the heating plate 14 and the sampling knife 10 to the lower part of the rotating screw 11 respectively, when the frozen meat is relatively hard, the surface of the sampling location of the frozen meat can be heated by the heating plate 14 first, reducing the surface hardness and making it easier for the sampling knife 10 to penetrate. In this way, it can greatly avoid the need for the operator to apply a lot of pressure at the beginning to make the sampling knife 10 penetrate, reducing labor intensity. In addition, the sampling knife 10 has the function of a container. After sampling, the meat sample can be taken out by rotating the sampling knife 10 upward under the pushing action of the rotating screw 11, which is convenient to use.

[0038] like Figure 4As shown, in this specific embodiment, the heating plate 14 can adopt the following specific structure: The heating plate 14 includes a connecting cover 1401 and a plate body 1402 that are detachably connected by bolts. A mounting screw hole is provided in the middle of the connecting cover 1401, which can be threadedly connected to the rotating screw 11. In this specific embodiment, a nut is welded onto the connecting cover 1401, and the inner hole of the nut is the mounting screw hole, communicating with the hole on the connecting cover 1401. The plate body 1402 is provided with a power supply and a resistance wire 1403. The resistance wire 1403 is electrically connected to the power supply via a switch. Specifically, a container is provided inside the plate body 1402. The cavity contains a partition that divides it into an upper and lower section. The partition has wiring holes. The power supply is located in the upper section, and the resistance wire 1403 is located in the lower section. A heat-conducting layer 1404 is connected to the partition via studs and is located below the resistance wire 1403. The switch is a toggle switch, and the connecting cover 1401 has a corresponding hole through which the toggle switch lever extends. Preferably, the lower part of the disc 1402 has an opening and a heat-conducting layer 1404. The diameter of the heat-conducting layer 1404 is not less than the diameter of the sampling blade 10. The heat-conducting layer 1404 is made of copper alloy, and its placement accelerates heat exchange.

[0039] like Figure 3 and Figure 5 As shown, in order to reduce cutting resistance, in this specific embodiment, the lower part of the blade tooth 12 has a conical structure, and the blade tooth 12 is also provided with a guide arc surface 1201. The projection of the guide arc surface 1201 on the lower end surface of the sampling knife 10 can be tangent to the outer edge of the sampling knife 10. The side of the guide arc surface 1201 near the outer circumferential surface of the sampling knife 10 is provided with a cutting edge 1202. The guide arc surface 1201 facilitates the cutting edge 1202 of the sampling knife 10 to cut frozen meat when it rotates, thereby reducing cutting resistance.

[0040] like Figure 3 As shown, for easier operation, in this specific embodiment, a sampling cone 13 is provided at the lower end of the rotating screw 11. The sampling cone 13 has threads on its conical surface. The sampling cone 13 can extend into the interior of the disc body 1402 or the cavity of the sampling knife 10. The sampling cone 13 is used to pierce the frozen meat. The sampling cone 13 and the rotating screw 11 are an integral structure. By providing a threaded sampling cone 13 at the lower part of the rotating screw 11, on the one hand, the sampling cone 13 can more easily enter the frozen meat during sampling, further reducing the cutting resistance. On the other hand, the sampling cone 13 can remain connected to the cut sample until the operator rotates it to remove it, preventing the sample from falling off during sampling.

[0041] like Figure 2 and Figure 3As shown, further, the tip of the sampling cone 13 can extend beyond the sampling knife 10. The tip of the sampling cone 13 is unthreaded. A spring 8 is provided between the rotating screw 11 and the turntable 7 on the lower surface of the supporting crossbar 3. The turntable 7 is rotatably mounted on the lower surface of the supporting crossbar 3 via a bearing. Specifically, a pressure plate 9 is provided on the rotating screw 11, and a spring 8 is provided between the pressure plate 9 and the limiting plate. The two ends of the spring 8 are connected to the pressure plate 9 and the turntable 7, respectively. With this configuration, before sampling, the operator pulls the rotating screw 11 upward until the spring 8 is compressed by the pressure plate 9 and the turntable 7, and then releases it. The spring 8 extends, causing the rotating screw 11 to move downward, so that the tip of the sampling cone 13 pierces the frozen meat. The operator judges the hardness by observing the mark, and then decides whether heating is needed. With this configuration in this specific embodiment, the operator can test the hardness of the frozen meat, avoiding misjudgment caused by the operator's judgment based on feeling, which affects the sampling efficiency.

[0042] The sampling blade 10 has sufficient depth to sample most frozen meats available on the market. Since frozen meats vary in thickness, to avoid piercing the support plate 1, such as... Figure 2 As shown, a limiting plate 6 is rotatably installed at the upper end of the rotating screw 11, and the limiting plate 6 can abut against the upper surface of the support crossbar 3. With this setting, the position of the limiting plate 6 can be adjusted according to the thickness of the frozen meat. When the rotating screw 11 is rotated downward, after the limiting plate 6 abuts against the upper surface of the support crossbar 3, it cannot continue to rotate downward, thereby limiting the position of the sampling knife 10 and preventing the knife teeth 12 from damaging the support plate 1.

[0043] like Figure 1 , Figure 2 and Figure 6 As shown, to limit the size of frozen meat of various sizes, a limiting fence 16 is provided on the support plate 1. A supporting boss 18 is provided on the inner wall of the limiting fence 16. The supporting boss 18 keeps the frozen meat at a certain distance from the support plate 1. This distance is not less than the length of the blade teeth 12, leaving space for the sampling knife 10 to cut through the frozen meat, ensuring that the meat sample is cut through. Multiple adjustment grooves 17 are provided on both the long and wide sides of the limiting fence 16. The adjustment grooves 17 pass through the supporting boss 18 and the openings of the adjustment grooves 17 face upwards. A positioning plate 4 is inserted into the limiting fence 16 through the adjustment grooves 17. The positioning plate 4 is provided with... Multiple adjustment slots are provided, with the openings of the adjustment slots facing upwards. Through the adjustment slots and adjustment slots, a positioning plate 2 5 is also provided between the limiting fence 16 and the positioning plate 4. The positioning plate 2 5 is perpendicular to the positioning plate 4. A secondary boss 19 is also provided on the side of the positioning plate 4 and the positioning plate 2 5 at the same height as the supporting boss 18, so as to achieve stable support for the frozen meat after the position is adjusted. By adjusting the positioning plate 4, the positioning plate 2 5, and the limiting fence 16, the operator can avoid fixing the frozen meat by hand. At the same time, by adjusting the adjustment slots 1 17 and adjustment slots 2, the size of the limiting area can be adjusted according to the size of the frozen meat to prevent the frozen meat from rotating and affecting the sampling.

[0044] like Figure 1 and Figure 2 As shown in this specific embodiment, two support vertical rods 2 are also arranged opposite each other on the support plate 1. Multiple adjustment holes are provided on the support vertical rods 2 along their height direction. Adjustment bolts are inserted through the adjustment holes. The adjustment bolts can be screwed to the end of the support horizontal rod 3. By setting the adjustment holes, the height of the support horizontal rod 3 can be adjusted, thereby adjusting the relative distance between the lower end of the rotating screw 11 and the frozen meat. This avoids the frozen meat being too thick and interfering with the sampling knife 10, making it difficult to install into the limiting area. It is suitable for frozen meat of various thicknesses.

[0045] To facilitate rotation, a steering wheel 15 is mounted on the top of the rotating screw 11.

[0046] The method of using this device is as follows:

[0047] Adjust the support crossbar 3 upwards to a suitable position, then remove positioning plate 4 and positioning plate 5, and place the frozen meat. After placing the frozen meat, move it to one corner of the limiting fence 16, insert positioning plate 4, and then insert positioning plate 5. Positioning plate 4 and positioning plate 5 should be in contact with the edge of the frozen meat or have a small gap with it to prevent the frozen meat from rotating. Adjust the height of the support crossbar 3 so that the sampling cone 13 is 2cm to 3cm away from the surface of the frozen meat. To test the hardness of the frozen meat, the operator lifts and rotates screw 11 until spring 8 is fully compressed, then releases it. The sampling cone 13 pierces the surface of the frozen meat. Observe the penetration depth of the sampling cone 13. If it is greater than the set position, then... No heating is required; the screw 11 can be rotated directly to take a sample. If the penetration depth is small, heating is required. Install the heating plate 14, set the heating time, and after heating, replace and install the sampling blade 10, tighten the nut 20, and then rotate to take a sample. When the limiting plate 6 abuts against the upper surface of the support crossbar 3, the blade teeth 12 of the sampling blade 10 are just located at the lower part of the frozen meat, achieving a thorough cut through the meat sample. The sampling cone 13 is screwed onto the cut meat sample. Move the sampling screw 11 upward, and the sampling blade 10 will lift the cut meat sample together. Then, rotate the abutting nut 20 upward and the sampling blade 10 to expose the cut meat sample. Remove the meat sample from the sampling cone 13.

[0048] Based on the above description, it can be seen that this specific implementation method has the following advantages:

[0049] 1. By screwing the heating plate 14 and the sampling knife 10 to the lower part of the rotating screw 11 respectively, when the frozen meat is hard, the surface of the sampling position of the frozen meat can be heated by the heating plate 14 first, reducing the surface hardness and making it easier for the sampling knife 10 to penetrate. This can greatly avoid the need for the operator to apply a lot of pressure at the beginning to make the sampling knife 10 penetrate, reducing labor intensity. In addition, the sampling knife 10 has the function of a container. After sampling, the meat sample can be taken out by rotating the sampling knife 10 upward under the pushing action of the rotating screw 11, which is convenient to use.

[0050] 2. Heat exchange can be accelerated by setting a thermally conductive 1404 layer;

[0051] 3. The partition is used to prevent the power supply from being affected by the 1403 resistor wire, which would affect the lifespan of the power supply.

[0052] 4. By setting a threaded sampling cone 13 at the lower part of the rotating screw 11, on the one hand, the sampling cone 13 can more easily enter the frozen meat during sampling, further reducing the penetration resistance; on the other hand, the sampling cone 13 can remain connected to the cut sample until the operator rotates it off, preventing the sample from falling off during sampling.

[0053] 5. By setting the sampling cone 13 to extend beyond the sampling knife 10, it is convenient for the operator to test the surface hardness of frozen meat at the beginning. The operator can judge whether heating is required based on the marks left by the sampling cone 13 on the surface of frozen meat, thus avoiding misjudgment caused by the operator's judgment based on feeling and affecting the sampling efficiency.

[0054] 6. The guide arc surface 1201 facilitates the cutting of frozen meat by the blade of the sampling knife 10 when it rotates, reducing cutting resistance;

[0055] 7. By setting the limiting plate 6, the distance between the limiting plate 6 and the support crossbar 3 can be adjusted according to the thickness of the frozen meat, so as to avoid the sampling knife 10 from damaging the support plate 1 under the frozen meat.

[0056] 8. By setting spring 8, it is possible to ensure that when different operators turn screw 11 to pierce frozen meat at the beginning of meat sample hardness test, the operator can easily ensure that the operator can pierce frozen meat with the same force. This avoids the influence of different operator forces on the judgment of hardness, making the hardness judgment more objective.

[0057] 9. By setting the limiting fence 16, positioning plate one 4 and positioning plate two 5, the size of the limiting area can be adjusted according to the size of the frozen meat, so as to prevent the frozen meat from rotating during sampling and improve the flexibility of the device.

[0058] 10. The height of the support crossbar 3 can be adjusted by setting the adjustment hole, thereby adjusting the relative distance between the lower end of the rotating screw 11 and the frozen meat, avoiding interference between the frozen meat and the sampling knife 10 due to its thickness, making it difficult to install into the limit area. It is suitable for frozen meat of various thicknesses.
