[0015] Figure 3 for Figure 2 A cross-sectional view of one of the cavity locations. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2As shown, a multi-purpose detection system for agricultural product contaminants includes a multi-purpose detection device 2 and a support tray 3 mounted on a detection platform 1. A cuvette 4 is placed within the cavity 30 of the support tray 3 by a lid. The support tray 3 is rotatably mounted on the detection platform 1. A rotatable follower tray 5 is coaxially mounted below the support tray 3. The follower tray 5 has an upper lifting mechanism 6 corresponding to the cavity 30 of the support tray 3. The cuvette 4 within the cavity 30 is suspended by the upper lifting mechanism 6 and moves up and down within the cavity 30 under the alternating action of the upper lifting mechanism 6 and its own gravity. The rotation of the tray 3 causes the cuvette 4 on it to rotate, and the upper mechanism 6 drives the cuvette 4 to move vertically, thereby keeping the sample solution in the cuvette 4 in a homogeneous state, avoiding precipitation that could lead to lighter or faded color, improving the accuracy of diversified detection of pollutants in agricultural products, and providing good homogenization and more thorough shaking, making it suitable for large-scale promotion and application.

[0018] More specifically, the diversified detection equipment 2 for agricultural product pollutants is a pesticide residue detector or a heavy metal detector. When a pesticide residue detector is selected, it can quickly detect organophosphorus and carbamate pesticide residues in agricultural products; when a heavy metal detector is selected, it can detect heavy metal elements in agricultural products, such as lead, mercury, and cadmium.

[0019] The testing platform 1 is provided with a base 7, and the mounting plate 3 is rotatably mounted on the base 7 via a corresponding shaft 8. The base 7 is provided with a forward / reverse drive unit connected to the shaft 8, which drives the follower plate 5 to rotate alternately in both forward and reverse directions. The forward / reverse drive unit is preferably a servo motor.

[0020] like Figure 2 and Figure 3 As shown, the lifting mechanism 6 includes an elastic air cushion 10, an air guide connector 11, and an air collection box 12. The follower disk 5 has an air guide hole 50, the elastic air cushion 10 covers the air outlet end of the air guide hole 50, and the air collection box 12 is connected to the air inlet end of the air guide hole 50 via the air guide connector 11. The side of the air collection box 12 has an air collection hole 12a. When the support disk 3 is rotating, the air collection box 12 collects air through the air collection hole 12a and transports it to the elastic air cushion 10 via the air guide connector 11 and the air guide hole 50, thus pushing the elastic air cushion 10 upwards to generate an upward force on the cuvette 4. The lifting mechanism 6 adopts a purely mechanical structure, with the initial power source for generating the upward force being the support disk 3. There are no other automated or electrical components, thus eliminating the problem of messy wiring when the support disk 3 rotates. The structure is simple while meeting the power requirements for the vertical movement of the cuvette 4.

[0021] The shelf 3 is powered by air when it rotates forward and backward. The cuvette 4 is deformed and raised upward, and the cuvette 4 is moved upward. During the interval between the forward and reverse adjustment of the shelf 3, the shelf 3 will stop briefly. At this time, there is no air source, the elastic air cushion 10 automatically contracts and sinks, and the cuvette 4 moves downward.

[0022] To prevent gas from entering through the gas collecting hole 12a and escaping through other gas collecting holes 12a, thus avoiding insufficient aerodynamic power, in this utility model, such as Figure 3 As shown, the air collecting holes 12a are distributed on the side of the air collecting box 12 facing the wind when the support plate 3 is rotated forward and backward. The air collecting box 12 is provided with a vertically extending baffle 12b inside. The baffle 12b divides the internal space of the air collecting box 12 into two parts corresponding to the distribution areas of the two air collecting holes 12a on the air collecting box 12.

[0023] To prevent gas from flowing between the two spaces of the gas collection box 12, the top of the baffle 12b extends into the gas outlet port of the gas collection box 12.

[0024] More specifically, the elastic air cushion 10 has an outer connecting ring 10a, which connects the elastic air cushion 10 to the follower disk 5 and covers the air inlet end of the air guide hole 50. This utility model includes a connecting rod 13, through which the follower disk 5 is connected to the support disk 3.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
