Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figure 1-Figure 5 This invention provides a technical solution: a fruit and vegetable pesticide residue detection device, comprising a sedimentation tank 1 and a homogenization frame 5. The sedimentation tank 1 and the homogenization frame 5 are vertically distributed and a connecting plate 11 is provided between them. The side wall of the connecting plate 11 is connected to the sedimentation tank 1 and the homogenization frame 5 respectively through a side connecting frame 10. The side connecting frame 10 is foldable. When the side connecting frame 10 is in the folded state, the connecting plate 11 can be stored in the sedimentation tank 1 and the homogenization frame 5 is snapped onto the upper surface of the connecting plate 11. A homogenization assembly is provided inside the homogenization frame 5, and the homogenization assembly includes: The internal fixed partition 6 is provided in multiple sets and is installed at equal intervals inside the homogenizing frame 5. The internal fixed partition 6 divides the homogenizing frame 5 into multiple rectangular processing chambers. The inner movable partition 7 is slidably connected inside the rectangular processing chamber, dividing the rectangular processing chamber into two homogenization chambers in the middle. The bottom of each homogenization chamber is equipped with a homogenization collection component.
[0019] During operation, before homogenization, the collection component is introduced into the homogenization chamber. Then, the fruit and vegetable samples to be tested are placed into each homogenization chamber. The inner movable partition 7 moves back and forth, repeatedly squeezing the fruit and vegetable samples on both sides until the fruit and vegetables are broken to achieve homogenization (the samples are squeezed by the inclined curved surface 701, which can reduce the splashing of fruit and vegetables out of the homogenization frame 5 during the squeezing process). After homogenization is completed, the collection component moves down and automatically removes the homogenized fruit and vegetables from the homogenization chamber, reducing sample loss. There are multiple sets of homogenization chambers, which can perform homogenization processing of multiple sets of fruit and vegetables at the same time, achieving efficient processing of fruit and vegetable samples. In this invention, the sedimentation tank 1, the connecting plate 11, and the homogenizing frame 5 are connected by a foldable side connecting frame 10. When not in use, the side connecting frame 10 is folded so that the connecting plate 11 is snapped onto the upper end of the sedimentation tank 1, and the homogenizing frame 5 is snapped onto the upper surface of the connecting plate 11. The collection components and the like can be stored inside the sedimentation tank 1, thus making the device a whole, saving space and reducing the number of instruments that need to be unloaded, which is convenient for transportation and carrying for on-site detection of pesticide residues in fruits and vegetables. When homogenization is required, the side connecting frame 10 is opened so that the connecting plate 11 and the homogenizing frame 5 can be unfolded above the sedimentation tank 1.
[0020] As a further embodiment of the present invention, a processing base plate 4 is fixedly installed on the lower surface of the homogenizing frame 5. A movable chamber 21 is provided in the middle of the processing base plate 4. The movable chamber 21 is rotatably connected to a limiting shaft 20 via a spring rod. In its natural state, the lower surface of the inner movable partition 7 is engaged with the limiting shaft 20. A through groove is provided on the processing base plate 4 at the position corresponding to the homogenizing chamber.
[0021] During operation, in the conventional transition state of this invention, the inner movable partition 7 is located in the middle of the rectangular processing chamber, and its lower end is engaged with the limiting shaft 20. When the inner movable partition 7 slides, its lower surface presses against the limiting shaft 20, causing the spring rod to contract, thereby eliminating the limiting effect on the inner movable partition 7 and allowing the inner movable partition 7 to move back and forth. After the movement, the limiting shaft 20 pops out again and is always in the middle of the rectangular processing chamber. The limiting shaft 20 acts as a barrier between the two homogenizing chambers, reducing the possibility of mutual penetration of the homogenized slurry on both sides.
[0022] As a further embodiment of the present invention, the homogenization collection assembly includes a homogenization collection plate 2, which is slidably disposed on the upper surface of the connecting plate 11. Multiple sets of telescopic rods 13 are fixedly installed on the homogenization collection plate 2 at positions corresponding to the homogenization chamber. An inlet plate 18 is fixedly installed at the upper end of the telescopic rods 13. Multiple sets of adsorption holes 19 are opened on the upper surface of the inlet plate 18. A negative pressure fan is provided at the bottom of the inlet plate 18. After the inlet plate 18 moves up into the homogenization frame 5, it can fit against the bottom of the processing base plate 4 and cover the through groove. A sleeve bag 17 is sleeved on the outside of the inlet plate 18. The negative pressure fan can make the sleeve bag 17 stick tightly to the surface of the inlet plate 18.
[0023] During operation, before homogenization, the homogenization collection plate 2 is slidably connected to the connecting plate 11, and the sleeve bag 17 is reversed and fitted onto the surface of the inlet plate 18. A negative pressure fan is activated to ensure that the sleeve bag 17 is tightly attached to the upper surface of the inlet plate 18. Then, the telescopic rod 13 extends, causing the inlet plate 18 to move upward and be sent into the homogenization chamber. The inner movable partition 7 slides on the surface of the inlet plate 18 to crush the fruits and vegetables. The crushed fruit and vegetable homogenate accumulates on the sleeve bag 17 on the surface of the inlet plate 18. After the homogenization and crushing are completed, the inlet plate 18 moves downward, causing the sleeve bag 17 to move downward as well. The sleeve bag 17 is then removed from the inlet plate 18 to obtain the fruit and vegetable homogenate that has been individually packaged, which facilitates subsequent detection liquid extraction and improves experimental efficiency.
[0024] As a further embodiment of the present invention, a linkage frame 8 is provided between the upper ends of multiple sets of internal movable partitions 7. Both sides of the internal movable partitions 7 are provided as inclined curved surfaces 701 that gradually widen from bottom to top. A mounting frame 22 is fixedly installed on one side of the homogenizing frame 5. Telescopic cylinders 9 are fixedly installed at both ends of the mounting frame 22. The output end of the telescopic cylinder 9 is fixedly connected to both ends of the linkage frame 8. The telescopic cylinder 9 can drive the internal movable partitions 7 to reciprocate within the rectangular processing chamber.
[0025] During operation, the telescopic cylinder 9 reciprocates, driving the linkage frame 8 to reciprocate. The linkage frame 8 drives multiple sets of internal movable partitions 7 to slide back and forth within the rectangular processing chamber, thereby achieving the goal of homogenizing multiple sets of fruits and vegetables simultaneously within a limited equipment volume without the slurries adhering to each other. The inclined curved surface 701 squeezes the sample, which reduces the splashing of fruits and vegetables out of the homogenization frame during the squeezing process.
[0026] As a further embodiment of the present invention, the side connecting frame 10 includes two sets of end connectors 1001, an intermediate connector 1002, and a locking nut 1003. The two sets of end connectors 1001 are rotatably connected to both ends of the intermediate connector 1002. The ends of the two sets of end connectors 1001 away from the intermediate connector 1002 are fixedly connected to the side walls of the sedimentation tank 1 and the processing bottom plate 4, respectively. Locking nuts 1003 are provided at the connection points of the end connectors 1001 and the intermediate connectors 1002.
[0027] In operation, the present invention connects the sedimentation tank 1 and the connecting plate 11, and the connecting plate 11 and the homogenizing frame 5 respectively through the side connecting frame 10. Loosening the locking nut 1003 of the side connecting frame and the folding device can store the connecting plate 11, the homogenizing frame 5, etc., reducing the space occupied.
[0028] As a further embodiment of the present invention, a cleaning plate 3 is slidably disposed on the upper surface of the connecting plate 11. A central groove 301 is provided in the middle position of the cleaning plate 3. Inclined grooves 302 inclined towards the central groove 301 are symmetrically disposed on the upper surface of the cleaning plate 3. A telescopic rod 13 is also fixedly installed on the cleaning plate 3 at the position corresponding to the homogenization chamber. A spraying component 12 is fixedly installed on the upper end of each telescopic rod 13. A disinfectant tank 303 is fixedly installed on one end of the cleaning plate 3. A main connecting pipe 16 is fixedly installed on each disinfectant tank 303. The main connecting pipe 16 passes through the middle of the telescopic rod 13. Multiple sets of pump suction devices 14 are fixedly installed on the main connecting pipe 16. A connecting conduit 15 is fixedly installed on the pump suction device 14. The other end of the connecting conduit 15 is fixedly connected to the spraying component 12. Multiple sets of transverse seepage grooves are provided on the connecting plate 11.
[0029] During operation, after homogenization and sampling, the homogenization collection plate 2 on the connecting plate 11 is replaced with the cleaning plate 3. The telescopic rod 13 on the cleaning plate 3 extends to insert the spraying component 12 into the homogenization chamber. The disinfectant is introduced into the spraying component 12 through the connecting conduit 15 by the pump 14. The water is sprayed out by the spraying component 12, thereby completing the cleaning of the equipment and avoiding the trouble of manual cleaning. The cleaning wastewater flows into the sedimentation tank 1 for collection through the middle groove 301 of the cleaning plate 3 and the seepage groove on the cleaning plate 11.
[0030] As a further embodiment of the present invention, both the homogenization collection plate 2 and the cleaning plate 3 can be housed inside the sedimentation tank 1, the connecting plate 11 can be snapped onto the upper end of the sedimentation tank 1, the edges of the connecting plate 11 are provided with snapping protrusions, and the lower surface of the processing base plate 4 is provided with snapping grooves corresponding to the positions of the snapping protrusions.
[0031] During operation, the homogenization collection plate 2 and cleaning plate 3 of this invention are stored in the sedimentation tank 1 for easy carrying.
[0032] As a further embodiment of the present invention, a sealing cap is snapped onto the upper end of the homogenizing frame 5, and a limiting protrusion is fixedly installed on the lower surface of the homogenizing collection plate 2 and the cleaning plate 3. A limiting groove is opened on the upper surface of the connecting plate 11, and the limiting protrusion is slidably connected to the limiting groove.
