The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-4As shown, this utility model provides a food testing and sample preparation mixing device, including a mixing cylinder 1 and a cover 2. The cover 2 covers the top opening of the mixing cylinder 1. A fastening mechanism 3 is provided on the outer wall of the mixing cylinder 1. Support blocks 4 are symmetrically fixedly installed on the outer wall of the cover 2. The fastening mechanism 3 and the support blocks 4 are fastened together to achieve a tight seal between the cover 2 and the mixing cylinder 1, ensuring the accuracy of sample preparation. The support block 4 is a Z-shaped structure, including a first connecting part horizontally fixed to the outer wall of the cover 2, a second connecting part perpendicular to the first connecting part and extending upward, and a third connecting part perpendicular to the second connecting part and extending outward. The end of the third connecting part is connected to the second connecting part. The top of the cover 2 is connected to the stirring cylinder 1. The inner wall of the fastening ring 9 is provided with a groove that matches the outer wall of the second connecting part and the bottom contour of the third connecting part. The groove is provided with a limiting protrusion for limiting the engagement with the outer wall of the support block 4, thereby firmly fixing the cover 2 to the stirring cylinder 1 and achieving a tight sealing effect. The top of the cover 2 is fixedly installed with a stirring motor 5. The output shaft of the stirring motor 5 is connected to a stirring roller 6 that extends into the stirring cylinder 1. Several stirring rods 7 are evenly distributed on the outer circumference of the stirring roller 6. When the stirring motor 5 is started, its output shaft rotates, which drives the stirring roller 6 to rotate inside the stirring cylinder 1, thereby performing stirring, shearing and turning functions on the food sample inside the stirring cylinder 1.

[0022] like Figure 1-4 As shown, the fastening mechanism 3 includes a support 8 fixedly installed on the outer wall of the mixing cylinder 1, a fastening ring 9 fastened to the support block 4, and a connecting rod 10 hinged to the support 8 via a rotating shaft. A connecting assembly 11 is connected to the end of the fastening ring 9, and the end of the fastening ring 9 is rotatably connected to the connecting rod 10 via the connecting assembly 11. The connecting assembly 11 allows the fastening ring 9 to rotate flexibly relative to the connecting rod 10 while connected to it, ensuring smooth movement of the fastening ring 9 during fastening and opening, thus achieving the fastening and disengagement actions with the support block 4. The connecting rod 10 has a U-shaped structure, with its two ends rotatably connected to the support block 4 via rotating shafts. Handles 12 are fixedly provided on the middle of the outer side wall of the connecting rod 10 on both sides of the support 8, so that the operator can apply force. By pulling the handle 12, the connecting rod 10 is driven to rotate around the pivot, thereby realizing the operation of the fastening ring 9. The connecting component 11 includes a rotating rod 13 fixedly connected to the end of the fastening ring 9 and a fixed rod 14 horizontally fixed through both sides of the connecting rod 10. The rotating rod 13 is rotated and sleeved on the fixed rod 14. After the cover 2 is closed on the stirring cylinder 1, the operator pulls the connecting rod 10, so that the fastening ring 9 rotates around the fixed rod 14 of the connecting component 11. The fastening ring 9 gradually approaches the support block 4 and finally fastens on the support block 4.

[0023] like Figure 1-4As shown, the edge of the cover 2 is provided with an annular groove 15. When the cover 2 is closed, the ends of the support 8 and the connecting rod 10 are located in the groove. The groove plays a role in positioning and accommodating, so that the fastening mechanism 3 can be housed inside the edge of the cover 2, ensuring the neatness of the overall appearance of the device. The contact surface between the cover 2 and the stirring cylinder 1 is provided with an annular sealing rubber ring, which is used to fill the tiny gap between the cover 2 and the stirring cylinder 1 to form a sealing effect, which helps to prevent sample leakage and external contamination.

[0024] In practical use, first, cover the top opening of the mixing drum 1 with the cover 2. At this time, the annular groove 15 on the edge of the cover 2 accommodates the support 8 and the end of the connecting rod 10, which serves as a positioning function. Then, pull down the handle 12, and the connecting rod 10 rotates around the axis of the support 8, which drives the fastening ring 9 to rotate around the fixing rod 14, so that the groove in the fastening ring 9 is fastened to the Z-shaped support block 4, realizing the tight seal between the cover 2 and the mixing drum 1. At the same time, the annular sealing rubber ring on the contact surface between the cover 2 and the mixing drum 1 is squeezed and deformed to fill the gap. To prevent leakage, start the stirring motor 5 to stir, shear, and turn the food sample to complete the sample preparation. After the sample preparation is completed, manually pull the handle 12 upwards to drive the connecting rod 10 to rotate around the support 8. The fastening ring 9 cooperates with the fixed rod 14 through the rotating rod 13, rotates around the fixed rod 14, and disengages from the support block 4. When the fastening ring 9 is completely released, the cover 2 can be removed and the sample can be taken out. Then, clean the inside of the stirring cylinder 1, the cover 2, the stirring roller 6, the stirring rod 7, and the fastening mechanism 3.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
