[0020] Lifting mechanism 8: It includes a rack plate 804, a mounting rod 805, and a gear 806. The mounting rod 805 is rotatably connected to the middle of the front wall of the protective cover 3. The gear 806 is provided in the middle of the outer arc surface of the mounting rod 805. The left and right sides inside the protective cover 3 are respectively provided with rack plates 804, and the rack plates 804 are meshed with the gears 806. The lifting mechanism 8 also includes a hexagonal sliding column 801, a lifting plate 802, and a mounting plate 803. The hexagonal sliding column 801 is slidably connected to the sliding holes opened on the left and right sides of the top wall of the housing 1. The lifting plate 802 is provided on the lower side of the outer arc surface of the hexagonal sliding column 801. The upper end of each of the two hexagonal sliding columns 801 is provided with a mounting plate 803. The upper end of each of the two mounting plates 803 is fixedly connected with a rack plate 804. The lifting mechanism 8 also includes an adjusting plate 80. 7. Connecting rod 808, central wheel 809, and adjusting rod 810. Adjusting plate 807 is located on the lower side of the rear end of rack plate 804 on the right side. Adjusting groove is provided on the left side of the rear end of adjusting plate 807. Connecting rod 808 is rotatably connected to the middle of the rear wall of protective cover 3. Central wheel 809 is provided on the front side of the outer arc surface of connecting rod 808. Adjusting rod 810 is provided on the lower side of the front end of central wheel 809. The front end of adjusting rod 810 is located inside the adjusting groove. Through the cooperation of rack plate 804 and gear 806, lifting plate 802 can be driven to perform vertical reciprocating motion, further increasing the contact area between food sample and crushing blade 7, preventing food sample from sinking to the bottom, reducing crushing dead angles, ensuring the crushing effect of food sample, and improving the accuracy of subsequent testing work.

[0021] It also includes a control switch group 2, which is located at the right end of the housing 1. The input terminal of the control switch group 2 is electrically connected to an external power supply and can regulate the electrical components inside the equipment.

[0022] Among them, a motor 9 is set in the middle of the rear end of the protective cover 3. The front end of the output shaft of the motor 9 is fixedly connected to the rear end of the connecting rod 808. The input end of the motor 9 is electrically connected to the output end of the control switch group 2. During the rotation of the crushing blade 7, the motor 9 starts to run through the control switch group 2. The output shaft of the motor 9 will drive the central wheel 809 to rotate through the connecting rod 808. The output shaft of the motor 9 and the central axis of the central wheel 809 are the same. When the central wheel 809 rotates, it will drive the adjusting rod 810 to rotate around the axis of the central wheel 809. Since the axis of the adjusting rod 810 does not coincide with the axis of the central wheel 809, the adjusting rod 810 will have lateral and vertical displacements during the circular motion.

[0023] The output rod 6 is rotatably connected to the middle of the top wall of the box 1. The lower side of the outer arc surface of the output rod 6 is respectively provided with crushing blades 7. The lower end of the output shaft of the drive motor 10 is fixedly connected to the upper end of the output rod 6. The input end of the drive motor 10 is electrically connected to the output end of the control switch group 2. By adjusting the control switch group 2, the drive motor 10 starts to run. The output shaft of the drive motor 10 drives the crushing blades 7 to rotate through the output rod 6, thereby crushing the food sample through the crushing blades 7.

[0024] Among them, the observation port at the middle of the front end of the box 1 is equipped with an observation window 11. During the crushing process, the operator can observe the actual situation inside the box 1 in real time through the observation window 11.

[0025] The working principle of the rapid sample preparation device for food testing provided by this utility model is as follows: During the use of the rapid sample preparation device for food testing, first open the door 4, then place the food sample into the interior of the chamber 1, and then close the door 4 again. At this time, through the control switch group 2, the drive motor 10 starts running. The output shaft of the drive motor 10 drives the pulverizing blade 7 to rotate through the output rod 6, thereby pulverizing the food sample through the pulverizing blade 7. During the rotation of the pulverizing blade 7, through the control switch group 2, the motor 9 starts running. The output shaft of the motor 9 drives the central wheel 809 to rotate through the connecting rod 808. The output shaft of the motor 9 and the central axis of the central wheel 809 are the same. The central wheel 809 rotates... When the adjusting rod 810 rotates around the axis of the central wheel 809, it will cause the adjusting rod 810 to rotate. Since the axis of the adjusting rod 810 and the central wheel 809 do not coincide, the adjusting rod 810 will have lateral and vertical displacements during its circular motion. At this time, the adjusting rod 810 will slide and rotate relative to each other inside the adjusting groove. When the adjusting rod 810 rotates downward, it will drive the right rack plate 804 to move downward through the adjusting plate 807. The right rack plate 804 will drive the right hexagonal slide column 801 to move downward through the right mounting plate 803. The right hexagonal slide column 801 will drive the right lifting plate 802 to move downward. At the same time, the right rack plate 804 will drive the right lifting plate 802 to move downward through the meshing connection during its downward movement. When gear 806 rotates, it meshes with the left rack plate 804, causing it to move upwards. The left rack plate 804, through the left mounting plate 803, moves the left hexagonal slide 801 upwards. The left hexagonal slide 801 then moves the left lifting plate 802 upwards. When adjusting rod 810 rotates upwards, it meshes with the adjusting plate 807, causing the right rack plate 804 to move upwards. The right rack plate 804, through the right mounting plate 803, moves the right hexagonal slide 801 upwards. The right hexagonal slide 801 then moves the right lifting plate 802 upwards. Simultaneously, as the right rack plate 804 moves upwards, it meshes with the left rack plate 802. The gear 806 rotates via a meshing connection. During rotation, the gear 806, through meshing, moves the left rack plate 804 downwards. The left rack plate 804, via the left mounting plate 803, moves the left hexagonal slide column 801 downwards. The left hexagonal slide column 801 then moves the left lifting plate 802 downwards, while the right side moves the lifting plate 802 vertically in a reciprocating motion. During this movement, the lifting plate 802 continuously tumbles the food sample, reducing dead zones in the crushing process. During crushing, the operator can observe the actual situation inside the chamber 1 in real time through the observation window 11. Once the food sample is crushed, the discharge valve is opened, and the crushed food sample is discharged through the discharge pipe 5.Food samples are pulverized into fine particles to facilitate subsequent chemical analysis or physical testing.

[0026] It is worth noting that the motor 9 disclosed in the above embodiments can be ECMA-C20604RS, the drive motor 10 can be 5IK200A-AF, and the control switch group 2 is provided with control buttons corresponding to the motor 9 and the drive motor 10 for controlling their switching.

[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
