The grinding assembly is set on the mounting frame 1 and includes two support plates 2. The two support plates 2 are fixedly connected to the front and rear inner walls inside the mounting frame 1, and a protective tank 3 is fixedly connected to the opposite sides of the two support plates 2.

[0028] Among them, the inner wall of the protective tank 3 is fixedly connected to the fixing sleeve 6, the inner wall of the fixing sleeve 6 is fixedly connected to the grinding tank 5, the lower surface of the grinding tank 5 is provided with multiple through holes 20 communicating with its interior, and the lower surface of the grinding tank 5 is fixedly connected to the mounting sleeve 19.

[0029] The inner wall of the mounting sleeve 19 is rotatably connected to a connecting shaft 13. The lower end of the connecting shaft 13 rotatably passes through the lower surface of the protective tank 3. A rotating plate 16 is fixedly connected to the front surface of the connecting shaft 13. Multiple hard brushes are provided on the upper surface of the rotating plate 16.

[0030] Among them, the front surface of the connecting shaft 13 is fixedly connected to the push plate 17, and the lower surface of the push plate 17 is in contact with the inner wall of the protective tank 3.

[0031] Furthermore, an L-shaped mounting rod 15 is fixedly connected to the lower surface of the protective tank 3, and a servo motor 14 is fixedly mounted on the rear surface of the L-shaped mounting rod 15;

[0032] The output end of the servo motor 14 is fixedly connected to the drive shaft 18, and the upper end of the drive shaft 18 is rotatably connected to the lower surface of the protective tank 3.

[0033] Furthermore, gears 12 are fixedly sleeved on both the outer wall of the drive shaft 18 and the outer wall of the mounting sleeve 19, and the two gears 12 mesh together.

[0034] Furthermore, a protective cover 10 is fixedly connected to the lower surface of the protective tank 3, and the two gears 12, the servo motor 14, the L-shaped mounting rod 15, and the connecting shaft 13 are all located inside the protective cover 10;

[0035] The lower surface of the protective tank 3 is fixedly connected to a discharge box 9 that communicates with the interior.

[0036] Furthermore, a cylinder mounting box 7 is fixedly mounted on the upper surface of the mounting bracket 1, and a cylinder is fixedly mounted inside the cylinder mounting box 7. The telescopic end of the cylinder slides through the interior of the mounting bracket 1.

[0037] Furthermore, a protective box 11 is fixedly connected to the telescopic end of the cylinder, and a drive motor is fixedly installed inside the protective box 11. A drive shaft is fixedly connected to the output end of the drive motor.

[0038] Furthermore, the lower end of the drive shaft rotates through the lower surface of the protective box 11, and a grinding block 8 is fixedly installed at the lower end of the drive shaft. The grinding block 8 and the grinding jar 5 are arranged vertically and vertically. The bottom of the mounting frame 1 is fixedly connected to an inclined receiving plate 4, and the receiving plate 4 and the discharge box 9 are arranged vertically and vertically.

[0039] Furthermore, when using this pretreatment equipment for solid food testing, the staff first puts the solid food to be tested into the grinding tank 5, and then starts the cylinder inside the cylinder mounting box 7 to drive the grinding block 8 into the grinding tank 5.

[0040] The drive motor inside the protective box 11 is started, and the output end of the drive motor drives the drive shaft and the grinding block 8 to rotate at high speed. The protruding structure of the grinding block 8 cooperates with the inner wall of the grinding tank 5 to perform preliminary crushing and grinding of solid food.

[0041] Meanwhile, the servo motor 14 is started. The output end of the servo motor 14 drives the gear 12 to rotate through the transmission shaft 18. Since the two gears 12 mesh with each other, the mounting sleeve 19 and the connecting shaft 13 rotate synchronously. The connecting shaft 13 drives the rotating plate 16 and the push plate 17 to rotate around the axis of the grinding jar 5.

[0042] Among them, the hard brush on the rotating plate 16 will penetrate into the inner wall of multiple through holes 20 at the bottom of the grinding tank 5, thereby cleaning the multiple through holes 20, preventing the multiple through holes 20 from becoming blocked, and then stopping the machine for cleaning, thus improving the practicality of the pretreatment equipment for solid food testing.

[0043] Among them, the lower surface of the push plate 17 is in contact with the inner wall of the protective tank 3. When it rotates with the connecting shaft 13, it pushes the ground food particles from the through hole 20 at the bottom of the grinding tank 5 to the discharge box 9, and finally falls on the receiving plate 4, realizing the synchronous operation of grinding and feeding.

[0044] During the grinding process, the rotation speed of the grinding block 8 can be adjusted by the drive motor (usually 1000-3000 r / min), while the rotation speed of the servo motor 14 can be adjusted according to the grinding particle size requirements (50-200 r / min) to ensure that solid foods of different hardness (such as grains, meat, etc.) can be fully crushed. The aperture of the through hole 20 is designed to be 2-5 mm, which can control the size of the grinding particles and meet the sample preparation requirements of different testing items.

[0045] When grinding is complete, the cylinder retracts and drives the grinding block 8 to reset. The protective cover 10 protects the internal transmission components and prevents food residue from entering moving parts such as the gear 12.

[0053] Push plate 17: fan-shaped structure (central angle 270°), the lower surface is in contact with the inner wall of the protective tank 3 (gap ≤ 0.3mm), and when it rotates with the connecting shaft 13, it generates centrifugal force to push the ground particles (particle size ≤ 5mm) from the through hole 20 to the discharge box 9 (pushing speed 0.2-0.5m / s) to avoid material residue (residual amount ≤ 5g / time).

[0054] Mounting sleeve 6 and mounting sleeve 19: Mounting sleeve 6 fixes the grinding jar 5 to the inner wall of the protective jar 3. It is made of polytetrafluoroethylene (PTFE) to reduce vibration transmission (vibration attenuation rate ≥40%). Mounting sleeve 19 supports the rotation of the connecting shaft 13 and has a built-in deep groove ball bearing (life ≥10,000 hours) to ensure smooth rotation without jamming.

[0055] Discharge box 9: Connected to the bottom of the protective tank 3, made of 304 stainless steel, with an internal inclined guide plate (30° inclination) to guide the grinding particles into the receiving plate 4, with a volume of 500mL and a discharge port size of 50mm×50mm, which can meet the sample feeding requirements of subsequent testing equipment.

[0056] Material receiving plate 4: Inclined (15° angle), smooth surface (roughness Ra≤0.8μm), made of food-grade polypropylene (PP), guides the material to the collection container to avoid accumulation (accumulation height≤10mm), and facilitates subsequent weighing and sample preparation.

[0057] Protective cover 10: Encloses transmission components such as gear 12 and servo motor 14. Made of transparent acrylic (5mm thick), with an IP54 protection rating, it prevents food residue from entering the gear meshing area (residue intrusion rate ≤0.01%) and facilitates observation of the internal transmission status.
