Description

Technical Field

[0001] The utility model belongs to the technical field of pesticide detection, and in particular relates to a rapid detection device for pesticide residues. Background Art

[0002] The rapid pesticide residue detection device is an instrument used to detect pesticide residues in vegetables, fruits, grains, tea, and soil. Its technical principles are primarily based on enzyme inhibition and photoelectric colorimetry. This method indirectly determines the amount of pesticide residue in a sample by detecting the inhibitory effect of pesticides on specific enzymes. The rapid pesticide residue detection device plays a vital role in ensuring food safety. It can quickly and accurately detect pesticide residues in agricultural products, preventing substandard food from entering the market and protecting consumer health. Furthermore, the device helps agricultural producers and processors promptly understand the pesticide residue status of their products, enabling them to adjust production and processing strategies and improve product quality and safety.

[0003] Chinese Patent Publication No. CN214539502U relates to the field of pesticide detection technology and discloses a rapid detection device for pesticide residues in agricultural products, comprising a housing, legs provided at the four corners of the bottom of the housing, a first motor provided above the housing, a feed port provided above one side of the housing, a stirring chamber provided above the interior of the housing, a water inlet provided on one side of the stirring chamber, a distilled water tank provided at the bottom end of the water inlet pipe, and a first stirring shaft provided inside the stirring chamber. This utility model provides heating plates on both sides of the detection chamber to facilitate heating the detection chamber, allowing the liquid in the detection chamber to react quickly. A second stirring shaft is provided inside the detection chamber to facilitate starting the second motor to drive the second stirring shaft to rotate continuously, thereby uniformly heating the liquid inside the detection chamber, accelerating the reaction speed of the pesticide, and improving the quality and efficiency of detection.

[0004] In actual use, the utility model can quickly screen pesticide residues in crops. It is necessary to fully mix the crop sample to be tested with a specific liquid so that the pesticide components in the mixed liquid can be effectively analyzed later. However, after completing a detection task, the existing rapid detection device for pesticide residues needs to wait for the detection device to be cleaned before the next detection can be carried out to ensure the accuracy of the next detection and avoid cross contamination. However, this process requires waiting for a certain amount of time, thereby interrupting the smoothness of the continuous detection operation, resulting in a reduction in overall detection efficiency, and making the use of the rapid detection device for pesticide residues less efficient.

[0034] Specifically, such as Figure 2 As shown, a plurality of cleaning brushes 13 are provided on the outside of the mounting shaft 8 , and the plurality of cleaning brushes 13 are all against the inner wall of the barrel 3 on one side.

[0035] Through its design, when the mounting shaft 8 rotates, it can drive multiple cleaning brushes 13 to rotate simultaneously, so that the residual crop samples or solutions to be tested in the placement barrel 3 can be cleaned conveniently and thoroughly, avoiding affecting the next pesticide residue detection, thereby ensuring the accuracy of the use of the pesticide residue rapid detection device.

[0036] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, a drive motor 14 is provided on one side of the upper end of the mounting plate 7.

When detecting them, the discharge hole 11 can be opened by moving the clamping plate 12, so that the liquid to be detected can enter the detection device body 2 through the feed pipe 25 for detection. When other crops need to be detected, the servo motor 17 needs to be started, and the output end of the servo motor 17 will drive the driving wheel 18 to rotate, and the driving wheel 18 will drive the outer gear ring 16 and the multiple placement barrels 3 to rotate, so that the crops after detection can be detected. The placement bucket 3 is rotated to the other side of the detection bucket 1, and the clean placement bucket 3 is rotated to the bottom of the first water inlet pipe 9. When cleaning the placement bucket 3, it is necessary to start the cylinder 6 to move the installation shaft 8 into the placement bucket 3 after use, and then start the drive motor 14. The output end of the drive motor 14 will drive multiple cleaning brushes 13 to rotate to clean the inner wall of the placement bucket 3.
