Description

Technical Field

[0001] This utility model relates to the field of pulverizing devices. More specifically, this utility model relates to a pulverizing device for meat veterinary drug testing. Background Technology

[0002] In the field of meat veterinary drug testing, efficient and accurate sample pretreatment is crucial for obtaining reliable test results. Patent publication number CN220912789U discloses a meat pulverizing device for veterinary drug testing. The control mechanism is located outside the main body, and the feeding mechanism is located at the bottom of the main body. The main body includes a pulverizing chamber with a lid hinged to its top. A rotary motor is fixedly connected to the top of the lid, and a rotating shaft is fixedly connected to the output end of the rotary motor. A mounting plate is fixedly connected to the surface of the rotating shaft. This invention, by setting a cleaning scraper, specifically places the meat into the pulverizing chamber, starts the rotary motor, and drives the rotating shaft to rotate. Simultaneously, the pulverizing blade assembly and the cleaning scraper rotate. While the pulverizing blade assembly pulverizes the meat, it scrapes off the meat adhering to the inner wall of the pulverizing chamber, facilitating pulverization, increasing the uniformity of meat pulverization, and improving the ease of cleaning the inner wall of the pulverizing chamber. However, this meat pulverizing device has gradually revealed some problems during processing. For example, during the pulverizing process, the temperature of the meat easily rises due to the biological characteristics of the meat itself and the heat generated by mechanical friction. Higher temperatures accelerate the growth and reproduction of microorganisms and changes in enzyme activity in meat, which can not only lead to meat spoilage and affect the accuracy of subsequent veterinary drug residue testing, but also alter the physical and chemical properties of the meat, changing its texture and viscosity, thus affecting the grinding effect and uniformity. Therefore, developing a device with cooling capabilities that can effectively grind meat is of significant practical importance for ensuring the accuracy and efficiency of veterinary drug testing in meat. Utility Model Content

[0003] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0004] Another objective of this invention is to provide a pulverizing device for veterinary drug testing of meat, which can cool the meat during the pulverizing process to prevent the heat generated by friction between the meat and the pulverizing structure from raising the temperature of the meat and affecting the accuracy and reliability of veterinary drug residue detection.

[0005] To achieve these objectives and other advantages according to the present invention, a meat pulverizing device for veterinary drug testing is provided, comprising:

[0006] The crushing box has a cylindrical structure, and a lid is provided on the top of the crushing box. The lid is snapped to the top of the crushing box.

[0007] A cooling structure is installed on the outside of the grinding chamber to cool the chamber walls.

[0008] The crushing structure is located on the lid of the container.

[0009] When the lid is closed on top of the grinding chamber, the grinding structure extends into the grinding chamber to grind the meat inside.

[0010] Preferably, the cooling structure is a semiconductor refrigeration chip, and the cooling end of the semiconductor refrigeration chip is attached to the wall of the crushing chamber.

[0011] Preferably, the outer side of the crushing box is provided with a shell component, which together with the upper part of the crushing box wall forms a water storage tank. The shell component and the middle and lower part of the crushing box together define a receiving cavity, which is filled with water-retaining cotton. A drain hole is provided at the bottom of the receiving cavity, and a through hole is provided at the bottom of the water storage tank to allow the water storage tank to communicate with the receiving cavity.

[0012] Preferably, the pulverizing structure includes:

[0013] The motor is fixedly mounted on the cover of the enclosure.

[0014] A rotating shaft, which is connected to the output shaft of the motor;

[0015] A shredder assembly is mounted on the rotating shaft.

[0016] Preferably, it also includes a scraper structure, the scraper structure comprising:

[0017] The mounting plate is fixedly connected to the rotating shaft;

[0018] A plurality of cleaning plates are arranged in a circular array at equal intervals along the circumference below the mounting plate.

[0019] Preferably, the edge of the cleaning plate that contacts the inner wall of the pulverizing chamber is designed to be wavy, with a wave height of 2-5 cm and a wavelength of 5-10 cm. At each peak and trough of the wave, sharp serrations are provided, with a serration height of 1-2 cm and a serration tip angle of 30-60°.

[0020] Preferably, the corrugated structure of the cleaning plate is made of fluororubber material.

[0021] Preferably, the wavy structure on two adjacent cleaning plates is configured such that the crests and troughs are opposite each other.

[0022] This invention offers at least the following advantages: First, by incorporating a cooling structure, such as a semiconductor cooling chip, on the outside of the grinding chamber, the chamber walls are cooled, preventing the meat from overheating due to friction during grinding. This helps maintain the original characteristics of the meat, preventing spoilage and changes in the veterinary drug components, thereby improving the accuracy and reliability of veterinary drug testing. Second, the motor in the grinding structure drives the rotating shaft and grinding blade assembly to grind the meat, while the scraper structure further enhances the grinding effect. The cleaning plate on the rotating shaft scrapes away meat adhering to the inner wall of the grinding chamber, allowing the meat to re-participate in the grinding process, increasing the uniformity of grinding, reducing meat residue, and improving grinding efficiency. Third, the outer shell of the grinding chamber forms a water storage tank and a receiving cavity. The water storage tank can store a certain amount of water. When cooling of the semiconductor cooling chip is needed, water flows through the through-hole into the water-storing cotton in the receiving cavity, using the water flow to cool the semiconductor cooling chip and enhance its cooling effect. The drainage hole at the bottom of the housing facilitates the discharge of excess water, so that water flow can be formed in the housing to carry away the heat generated by the semiconductor cooling chip.

[0023] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0030] like Figure 1 As shown, this utility model provides a pulverizing device for meat veterinary drug testing, which includes:

[0031] The crushing box 1 has a cylindrical structure, and a box cover 2 is provided on the top of the crushing box 1. The box cover 2 is snapped to the top of the crushing box 1.

[0032] A cooling structure is provided on the outside of the crushing chamber 1 to cool the walls of the crushing chamber 1.

[0033] The crushing structure is located on the box cover 2;

[0034] When the lid 2 is closed on top of the crushing box 1, the crushing structure penetrates into the crushing box 1 to crush the meat inside the crushing box 1.

[0035] In this technical solution, the crushing box 1 is made of stainless steel, with an inner diameter of approximately 30 cm and a height of approximately 40 cm. It possesses good corrosion resistance and strength, capable of withstanding certain mechanical impacts and pressures. The box wall thickness is approximately 3 mm to ensure it will not deform due to external forces during the crushing process. The top edge of the crushing box 1 has a snap-fit ​​groove for a tight connection with the lid 2, preventing the lid from rotating relative to the crushing box 1 when closed. The lid 2 is also made of stainless steel with a thickness of approximately 5 mm to ensure sufficient strength. A mounting base is located at the center of the lid 2 to secure the crushing structure. The edge of the lid 2 is machined with snap-fit ​​protrusions that match the top of the crushing box 1. Rotating the lid 2 allows for a secure snap-fit ​​connection with the crushing box 1, ensuring that the lid 2 will not loosen or leak during the crushing process. The refrigeration structure can use a TEC1-12706 semiconductor cooling chip 3, with its cooling end tightly attached to the outer wall of the crushing chamber 1. The heating end of the semiconductor cooling chip 3 can be equipped with a heat sink made of aluminum alloy, which has a large heat dissipation area to ensure that the cooling chip can work continuously and efficiently. During the refrigeration process, the temperature inside the chamber can be stably controlled at about 5 ℃ by an external temperature controller to prevent meat spoilage and changes in veterinary drug components from interfering with the test results. The pulverizing structure includes a motor 7, a rotating shaft 8, and a pulverizing blade assembly 10. The motor 7 can be selected with a power of 500 W, which has a high speed and torque to meet the requirements for pulverizing meat. The motor 7 is fixed to the mounting base on the cover 2 with bolts to ensure that it will not shift during operation. The rotating shaft 8 can be made of stainless steel, with a diameter of 2 cm and a length of 35 cm, which can stably transmit the power of the motor 7. The rotating shaft 8 and the output shaft of the motor 7 are connected by a coupling to ensure tightness and concentricity of the connection. The pulverizing blade assembly 10 can be composed of 6 high-speed steel pulverizing blades. The blades are spirally distributed on the rotating shaft 8, with an included angle of approximately 60° between adjacent blades. The blade edges are specially treated to be sharp and wear-resistant, which can effectively cut and pulverize meat. The motor 7 and the cooling structure can be powered by an external power source.

[0036] In practical use, the meat to be tested is first placed into the grinding chamber 1, then the lid 2 is closed, ensuring the latches are securely fastened. The cooling system is then activated to lower the temperature inside the grinding chamber 1 to the set value. Next, the motor 7 is started, driving the rotating shaft 8 and the grinding blade assembly 10 to rotate at high speed, grinding the meat. During the grinding process, the cooling system continues to operate, maintaining a low-temperature environment. After grinding is complete, the motor 7 and the cooling system are turned off, the lid 2 is opened, and the ground meat is removed for subsequent veterinary drug testing. This meat veterinary drug testing grinding device can effectively achieve low-temperature grinding of meat, improving the accuracy and reliability of veterinary drug testing.

[0037] In another technical solution, a shell component 6 is provided on the outside of the crushing box 1. The shell component 6 and the upper part of the box wall of the crushing box 1 together form a water storage tank 4. The shell component 6 and the middle and lower part of the crushing box 1 together define a receiving cavity 5. The receiving cavity 5 is filled with water storage cotton. A drain hole is provided at the bottom of the receiving cavity 5. A through hole is provided at the bottom of the water storage tank 4 to allow the water storage tank 4 to communicate with the receiving cavity 5.

[0038] In this technical solution, the shell part 6 can be made of engineering plastic material, such as ABS plastic, which has good molding performance and certain mechanical strength, as well as good corrosion resistance and insulation; its shape is slightly larger than the crushing box 1 so as to form an annular water storage tank 4 and a receiving cavity 5 between the shell part 6 and the crushing box 1; the water storage tank 4 can store a certain amount of water for cooling. A water inlet is provided at the top of the water storage tank 4 for easy water addition. The water inlet is equipped with a sealing cap to prevent water from splashing out during crushing. An air pressure balance hole is provided in the middle of the sealing cap. The receiving cavity 5 is defined by the shell part 6 and the lower middle part of the crushing box 1. The receiving cavity 5 is filled with water-retaining cotton with a thickness of 5 cm. The water-retaining cotton is made of a material with strong water absorption and a certain water retention, such as polyester fiber cotton. The water-retaining cotton is tightly arranged in the receiving cavity 5 to ensure that it can fully absorb the water flowing in from the water storage tank 4. There are 4 through holes evenly distributed at the bottom of the water storage tank 4, each with a diameter of 5 mm. The through holes are designed at an angle of 45 degrees to the horizontal direction so that water can flow smoothly into the receiving cavity 5 under the action of gravity and be evenly distributed on the water-retaining cotton. A drain hole with a diameter of 10 mm is provided at the bottom of the receiving cavity 5. The drain hole can be connected to a drain pipe to remove the heat generated by the semiconductor cooling chip 3 through the discharge of water.

[0039] In another technical solution, the cooling structure is a semiconductor cooling chip 3, and the cooling end of the semiconductor cooling chip 3 is attached to the wall of the crushing box 1.

[0040] In this technical solution, the semiconductor cooler 3 can be a TEC1-12706 model. This cooler measures 40 mm × 40 mm × 3.4 mm and has high cooling power and efficiency, making it suitable for use in this meat veterinary drug testing pulverizer. The heating end of the semiconductor cooler 3 is equipped with a heat sink assembly. The heat sink is made of aluminum alloy with a wave-shaped fin structure to increase the heat dissipation area. The fin thickness is 0.5 mm, and the spacing between adjacent fins is 3 mm. During actual operation, an external power supply provides the semiconductor cooler 3 with a 12 V operating voltage, connected to a temperature controller. The temperature sensor of the temperature controller is installed inside the pulverizing chamber 1 and can automatically adjust the working state of the semiconductor cooler 3 according to a preset temperature value (e.g., 4-5 ℃). When the temperature inside the pulverizing chamber 1 is higher than the set temperature, the cooler increases its cooling power; when the temperature approaches or reaches the set temperature, the cooler reduces its power or stops working, thereby achieving precise temperature control inside the pulverizing chamber 1 and providing a stable low-temperature pulverizing environment for meat veterinary drug testing.

[0041] In another technical solution, the crushing structure includes:

[0042] Motor 7 is fixedly mounted on the cover 2;

[0043] Rotating shaft 8 is connected to the output shaft of motor 7;

[0044] The shredder assembly 10 is mounted on the rotating shaft 8.

[0045] In this technical solution, the rotation of motor 7 drives the pulverizing blade assembly 10 to rotate, thereby pulverizing the meat in the pulverizing box 1. The pulverizing structure can be designed with reference to the pulverizing blade assembly (pulverizing blade assembly 107 in the patent) in Chinese Patent Publication No. CN220912789U.

[0046] In another technical solution, a scraper structure is also included, the scraper structure comprising:

[0047] Mounting plate 9 is fixedly connected to rotating shaft 8;

[0048] A plurality of cleaning plates 11 are arranged in a circular array at equal intervals along the circumference below the mounting plate 9.

[0049] In this technical solution, the cleaning plate 11 is used to scrape off the meat adhering to the inner wall of the pulverizing box 1. This structure can be designed with reference to the pulverizing blade assembly (pulverizing blade assembly 107 in the patent) in Chinese Patent Publication No. CN220912789U.

[0050] In another technical solution, the edge of the cleaning plate 11 that contacts the inner wall of the pulverizing chamber is designed as a wave-like structure. The height of the wave is 2-5 cm and the wavelength is 5-10 cm. Sawtooth 14 is provided at each peak and trough of the wave. The height of the sawtooth 14 is 1-2 cm and the angle of the tooth tip is 30-60°.

[0051] In this technical solution, when the motor 7 drives the rotating shaft 8 to rotate, the wavy serrated scraper 14 rotates accordingly. When it comes into contact with the meat adhering to the inner wall of the crushing chamber 1, the wavy edge contacts the meat first. Due to the undulation of the waves, the contact angle and force between the scraper and the meat at different positions constantly change, increasing the scraping effect. At the same time, the serrated structure further enhances the ability to cut and peel the meat, enabling more effective scraping of stubborn, adhered meat from the inner wall. Moreover, this shape of scraper also generates a certain agitation effect on the meat during rotation, making the meat more evenly distributed within the crushing chamber 1, which is beneficial for the crushing blade assembly 10 to more thoroughly crush the meat.

[0052] In another technical solution, the corrugated structure of the cleaning plate is made of fluororubber. During the frequent scraping of the inner wall of the grinding chamber by the cleaning plate, the high elasticity of the fluororubber allows it to adhere tightly to the inner wall, effectively removing adhering meat material. It is also less prone to damage from friction, maintaining a long-term stable scraping effect, ensuring the cleanliness of the grinding chamber and the uniformity of meat grinding, reducing meat residue, and improving grinding efficiency.

[0053] In another technical solution, the wavy structure on two adjacent cleaning plates is configured with crests and troughs facing each other. Driven by a motor, the rotating shaft causes the cleaning plates to rotate. This design of opposing crests and troughs increases the contact area and range of action between the cleaning plates and the inner wall of the grinding chamber and the meat. Compared to conventional arrangements, this structure can apply force from more angles and positions when scraping off adhering meat, resulting in more thorough scraping. It also enhances the agitation of the meat, promoting a more uniform distribution within the grinding chamber, improving grinding efficiency and uniformity, ensuring thorough grinding, and facilitating the acquisition of consistent veterinary drug test samples.

[0054] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
