[0033] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0034] Please see Figure 1 and Figure 2 This utility model provides a filtration device for testing the quality and safety of agricultural products, comprising: a housing 1, two crushing rollers 4, and a squeezing and opening assembly 3. Two rotating shafts 2 are rotatably installed on the inner wall of the housing 1. The two crushing rollers 4 are respectively fixed on the arc surfaces of the two rotating shafts 2. A support plate 6 is fixedly connected to one side of the outer wall of the housing 1. A drive motor 7 is fixedly connected to one side of the support plate 6.

The two gears 5 mesh with each other. The squeezing and opening assembly 3 is located on the housing 1.

[0035] In the embodiments of this utility model, please refer to Figures 3 to 6The extrusion opening and closing assembly 3 includes a support platform 301 and a side plate 310. The support platform 301 is fixedly connected to the inner wall of the housing 1. The cross-section of the support platform 301 is a right trapezoid. A rectangular hole 302 is opened on one side of the support platform 301. An extrusion plate 303 is attached to the inner wall of the rectangular hole 302. A lead screw 304 is threaded through the side of the extrusion plate 303. One end of the lead screw 304 is rotatably connected to the inner wall of the housing 1. A servo motor 305 is fixedly connected to the inner wall of the rectangular hole 302. The output end of the servo motor 305 is fixedly connected to one end of the lead screw 304. A filter plate 308 is fixedly connected to the inner wall of the housing 1. A plurality of filter holes 309 are opened on the surface of the filter plate 308. The lower part of the filter plate 308... The surface and the upper surface of the extrusion plate 303 are in the same plane. The inner wall of the box 1 is equipped with a collection box 318. The side plate 310 is attached to the inner wall of the box 1. Sliding holes 311 are opened on both sides of the outer wall of the box 1. A sliding rod 312 is slidably connected to the inner wall of the sliding hole 311. One end of the sliding rod 312 is fixedly connected to the side plate 310. An adjusting ring 313 is threadedly connected to the arc surface of the sliding rod 312. By setting the extrusion opening and closing component 3, two effects are achieved: First, after the crop is crushed, the extrusion plate 303 can be automatically adjusted to extrude the slurry on the filter plate 308, thereby further squeezing out the slurry in the slurry, so that the raw material to be tested can be more fully processed, and the testing efficiency is improved.Secondly, after use, the side of the box 1 can be easily opened, facilitating cleaning and maintenance and extending the service life of the filter device for agricultural product quality and safety testing. A guide rod 307 slides through the side of the extrusion plate 303. The two ends of the guide rod 307 are fixedly connected to one side of the inner wall of the rectangular hole 302 and one side of the inner wall of the box 1, respectively. When the lead screw 304 rotates to drive the extrusion plate 303 to move, the guide rod 307 can guide and position the extrusion plate 303, thereby improving the efficiency of the extrusion plate 303's movement. To improve stability, an elastic sealing sleeve 306 is fitted onto the arc surface of the lead screw 304. The two ends of the elastic sealing sleeve 306 are fixedly connected to one side of the extrusion plate 303 and one side of the inner wall of the housing 1, respectively.

A sealing ring 317 is fixedly connected to the side of the side plate 310 away from the housing 1, with one side of the sealing ring 317 being flush with the housing 1.

The adjusting ring 313 is fixedly connected to a rubber pad on the side near the housing 1. 314. The diameter of the rubber pad 314 is larger than that of the adjusting ring 313. The rubber pad 314 can increase the friction of the adjusting ring 313 on the side close to the housing 1, so that the adjusting ring 313 can be more firmly abutted against the housing 1 with the help of the rubber pad 314. A handle 316 is fixedly connected to the arc surface of the two slide rods 312. The cross section of the handle 316 is "U". Moving the handle 316 can drive the slide rod 312 to move, and the slide rod 312 drives the side plate 310 to move, so as to achieve the effect of convenient control of the side plate 310.

[0036] The working principle of the filtration device for agricultural product quality and safety testing provided by this utility model is as follows: When it is necessary to use this device to crush and test agricultural products, the drive motor 7 is started first to drive one of the rotating shafts 2 to rotate. This rotating shaft 2 drives the other rotating shaft 2 to rotate through the gear 5. The rotating shaft 2 drives the crushing roller 4 to rotate. When the two crushing rollers 4 rotate simultaneously, the agricultural products to be crushed are placed into the box 1. At this time, the two crushing rollers 4 will crush the agricultural products. The crushed material and slurry will fall onto the filter plate 308 along the inclined surface of the support platform 301. The filter holes 309 on the filter plate 308 will filter the mixture of crushed material and slurry. The slurry will fall into the storage box at the bottom of the box 1 along the filter holes 309. During the process, the servo motor 305 is started to drive the lead screw 304 to rotate. The lead screw 304 drives the extrusion plate 303, causing the extrusion plate 303 to move along the surface of the filter plate 308 to extrude the crushed material and slurry, thereby further extracting the slurry from the crops. After the slurry is collected, the servo motor 305 is started to drive the lead screw 304 to rotate. The lead screw 304 drives the extrusion plate 303 to return to its original position. When the lead screw 304 rotates and drives the extrusion plate 303 to move, the guide rod 307 can guide and position the extrusion plate 303, thereby improving the stability of the extrusion plate 303 during the movement process. After the extrusion plate 303 returns to its original position, the adjusting ring 313 is rotated to separate the rubber pad 314 from the box 1, releasing the restriction on the side plate 310. The handle 316 is then moved to drive the slide rod 312, causing it to move along the inner wall of the sliding hole 311. The sliding hole 311 then moves the side plate 310 upwards. Once the side plate 310 is open, the personnel can remove the collection box 318 containing the slurry from inside the box 1. Solvent is then added to the collection box 318 to extract the pesticide components for testing. At this point, the mixture inside the collection box 318 can be used for agricultural product quality and safety testing. After testing, the collection box 318 is cleaned and placed back into the box 1. The debris on the filter plate 308 is removed. Then, the handle 316 is moved to drive the slide rod 312, which in turn moves the side plate 310, sealing the side of the box 1. Finally, the adjusting ring 313 is rotated to move the rubber pad 31. 4. By abutting against the housing 1, the side plate 310 is fixed. The elastic sealing sleeve 306 covers and protects the lead screw 304, preventing fiber and slurry from adhering to the arc surface of the lead screw 304 during use, thus improving its service life. Additionally, the sealing ring 317 seals the tiny gaps between the side plate 310 and the housing 1, improving the sealing at the connection. As the slide rod 312 slides along the inner wall of the sliding hole 311, the positioning rod 315 guides and positions it, improving the stability of its movement. Finally, the rubber pad 314 increases the friction of the adjusting ring 313 near the housing 1.This achieves a more stable connection between the adjusting ring 313 and the housing 1, thanks to the rubber pad 314.

[0037] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
