[0002] Food testing is for food safety. Food samples are taken for testing to determine whether the content in the food is harmful to the human body. During the testing, food samples need to be taken. For some harder foods, such as fruits with cores or frozen foods, they need to be crushed first, and then the powder is taken for relevant chemical testing to detect the internal ingredients and whether there are any food safety issues.

[0003] There are many food crushing and sampling devices in the prior art, some of which use blenders for crushing and sampling, and some use meshing teeth for crushing and sampling. However, when these devices are used, some foods with cores or frozen foods cannot be crushed thoroughly due to insufficient crushing force of the blender. Using meshing teeth for crushing is not convenient to carry and cannot be crushed and sampled in time.

A groove is provided on the bottom edge of the feed chamber 8 so that the crushing chamber 4 can be plugged into the feed chamber 8. The split design is adopted to facilitate carrying and convenient cleaning of the interior to prevent residues from mixing in when different foods are crushed in sequence, resulting in inaccurate detection. A through groove 11 is provided on the crossbeam of the support frame 2. A movable column 12 is provided on the opposite surface of the vertical bracket of the support frame 2. A slide groove 13 is provided on the movable column 12. A linear gear plate 14 is slidably connected to the slide groove 13. A support arm 15 is fixed on the side of the linear gear plate 14 away from the crushing chamber 4. A crushing column 16 is provided at one end of the support arm 15 away from the linear gear plate 14. The driving gear 7 is engaged with the linear gear plate 14 to drive the crushing column 16 to move downward, thereby preliminarily crushing the food. The active crushing teeth 5 and the driven crushing teeth 6 are then used to crush the food for the second time to improve the crushing effect.

[0022] Among them, an inclined plate 9 is fixed inside the feeding chamber 8. The inclined plate 9 is inclined downward, and the opening position is opposite to the meshing center of the active crushing teeth 5 and the driven crushing teeth 6. During the secondary crushing, the sample can fall directly from the inclined plate 9 between the active crushing teeth 5 and the driven crushing teeth 6 to prevent the sample from leaking from the edges of the active crushing teeth 5 and the driven crushing teeth 6, thereby further improving the crushing effect. Bearing seats 10 are provided on both the feeding chamber 8 and the crushing chamber 4 to facilitate the stability of the active crushing teeth 5 and the driven crushing teeth 6 on the crushing chamber 4.

[0023] Among them, a discharge hopper 23 is fixedly provided below the crushing chamber 4, and the discharge hopper 23 is inclined toward the center. On the base 1, a storage limit seat 17 is fixedly provided just below the discharge port 23. The storage is an iron circular container and can be directly placed on the storage limit seat 17 for easy sampling and storage.

[0024] Among them, a limiting support column 19 is provided on the side of the movable column 12 facing the vertical bracket of the support frame 2. One end of the limiting support column 19 is fixedly connected to the movable column 12, and the other end is slidingly connected to the support frame 2. A movable control rod 18 is provided on the same surface of the support frame 2 as the limiting support column 19. The movable control rod 18 passes through the support frame 2. One end of the movable control rod 18 is rotatably connected to the movable column 12, and the other end is threadedly connected to the support frame 2. By moving the control rod 18 forward or backward, the movable column 12 is controlled to move forward and backward, which facilitates the engagement of the linear gear plate 14 with the driving gear 7 to connect and move the rolling column 16.

[0025] Among them, the limiting support column 19 is provided with a corresponding hole on the support frame 2, the length of the limiting support column 19 is smaller than the moving control rod 18, and the limiting support column 19 is located inside the support frame 2 and is provided with a limiting block. The diameter of the limiting block is larger than the diameter of the limiting support rod 19, which prevents the moving column 12 from detaching from the support frame 2, and also enables the limiting support column 19 to provide support for the moving column 12 to improve stability.

[0026] Among them, a transmission rod 20 is fixedly provided at the center of the active crushing teeth 5 and the driven crushing teeth 6. The transmission rod 20 on the active crushing teeth 5 is fixedly connected to the center of the driving gear 7. A rotating bearing 21 is provided on the transmission rod 20. A rotating rod 22 is fixedly provided at the end of the transmission rod 20 on the active crushing teeth 5 away from the driving gear 7. By manually rotating the rotating rod 22, the active crushing teeth 5 are driven to rotate to crush the food.

[0027] The teeth on the linear gear plate 14 are of the same size as the teeth on the drive gear 7 , and when in contact, they mesh with each other, making it convenient to connect the linear gear plate 14 and the drive gear 7 , and to use the drive gear 7 to complete the driving action.

[0028] Among them, the crushing column 16 is provided with a hole in the same direction as the support arm 15. The support arm 15 is bent downward and inserted into the hole on the crushing column 16. The support arm 15 is used to stay away from the drive gear 7 to prevent it from hindering the movement of the drive gear 7. Secondly, the support arm 15 drives the crushing column 16 to move downward, increasing the pressure to crush the food.

[0029] Among them, the storage is placed on the storage limit seat 17, the center position of the discharge hopper 23 is a circular structure, and the circular structure is tilted and designed to correspond to the storage inlet. The storage is made of iron, which is convenient for receiving materials.

[0030] Among them, ejectors are evenly distributed on the bottom surface of the crushing column 16, and the ejectors are used to position and crush the food so that the food can be crushed thoroughly.

[0031] Specifically, when in use, first place the active crushing teeth 5 on the crushing chamber 4, then move the moving control rods 18 on both sides of the support frame 2 to drive the moving column 12 to move in the direction of the driving gear 7, so that the linear tooth plate 14 is meshed with the driving gear 7. At this time, the support arm 15 and the crushing column 16 are plugged in, and the food is placed in the storage so that the opening of the storage corresponds to the crushing column 16. Then, rotate the rotating rod 22 to make the driving gear 7 drive the linear tooth plate 14 to move downward, driving the crushing column 16 to squeeze the food, and the thimble on the crushing column 16 will crush the food. Fix and crush the food to perform preliminary crushing. After the preliminary crushing, move the movable control rods 18 on both sides of the support frame 2 to disconnect the driving gear 7 from the linear tooth plate 14, and then install the driven crushing teeth 6 on the crushing chamber 4 to engage the active crushing teeth 5 and the driven crushing teeth 6. Then install the feeding chamber 8 on the crushing chamber 4, place another storage on the storage limit seat 17, and then pour the preliminary crushed food from the feeding chamber 8. Rotate the rotating rod 22 to crush the food for the second time. The crushed food will be output from the discharge hopper 23 and enter the storage to complete the sampling.
