Description

Technical Field

[0001] This invention belongs to the technical field of pesticide experimental equipment, and in particular relates to a pesticide selection instrument for pests. Background Technology

[0002] Traditional farmers' pesticide application habits are no longer compatible with current standards. The overuse of chemical pesticides and the persistent use of a single pesticide in the same field year after year are difficult to curb. This situation not only damages the field's ecological environment but also limits production profits due to low control efficiency and wasted funds from repeated applications. This leads to a progressively increasing problem of pest resistance, even creating a vicious cycle of "the more pesticides used, the harder it is to control; the harder it is to control, the more pesticides are used." Therefore, precise pesticide selection is urgently needed. Traditional pesticide screening methods—indoor bioassays and field efficacy trials—have shortcomings in terms of timeliness and accuracy, require significant time investment from professionals, and the subjective judgment of the results cannot be guaranteed. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a pesticide selection device that fills the research gap in pesticide screening throughout the entire process of precision pesticide application. Through intelligent, convenient, and high-throughput design concepts, it achieves targeted pesticide screening, improves pesticide utilization, and reduces economic losses caused by repeated pesticide use by growers while taking into account environmental protection, thereby improving the effectiveness of pest control in the production process from the root.

The acquired image data is transmitted to the background through the external network interface, and the mortality rate is statistically analyzed by the pest identification model, thereby completing the pesticide screening.

[0024] In this embodiment, the front and rear drive motors and the up and down drive motors 18 are stepper motors. The purpose of the stepper motors is to accurately control the position of the dispensing needle and the nozzle, and to prevent positional deviations.

[0025] like Figure 4 As shown, in this embodiment, the original liquid plunger pump 8 is connected to the dispensing needle 19 via a pipeline to provide pressure for the dispensing needle 19 to extract the original pesticide liquid from the pesticide placement area. The pesticide dilution area includes a dilution tank and an inlet tank. The original liquid extracted by the dispensing needle 19 first enters the dilution tank. The dilution plunger pump 9 and the mixing plunger pump 10 are connected to a pure water bottle via pipelines. The dilution plunger pump 9 extracts pure water from the pure water bottle and enters the dilution tank to complete the first dilution of the pesticide liquid. The mixing plunger pump 10 extracts pure water from the pure water bottle and enters the inlet tank to perform a second dilution of the pesticide liquid. The two-stage gradient dilution can achieve a dilution ratio of 10-1000 times. After the two dilutions, the pesticide is sprayed into each test tank of the insect test plate 15 through a nozzle. The cleaning pump 11 is connected to a pure water bottle to clean the pipeline with the extracted clean water. Under the action of the waste liquid pump 7, the waste liquid is discharged into the waste liquid tank through the waste liquid pipe.

[0027] In this embodiment, a light source 16 is provided at the bottom of the insect testing board 15. The light source 16 can be an LED light-emitting panel. Since the insect testing board 15 is also made of acrylic material, the light source generated by the LED light-emitting panel can illuminate the transparent acrylic material and provide a light source for the ultra-high-definition camera 20 to take pictures.

[0028] In this embodiment, the nozzle is an ultrasonic atomizing nozzle. The diluted pesticide solution is driven to the corresponding test tank by a drive device for spraying. A 0.1mm-0.2mm liquid film is formed at the bottom of the test tank, ensuring full contact between the pesticide and the insects and preventing drowning. The liquid path also supports the special experimental requirement of adding undiluted concentrate for direct spraying. After the experiment, pure water is pumped to clean the pipeline and nozzle, and the waste liquid is discharged into a waste liquid tank.

[0029] like Figure 5 As shown, the working process of this invention is as follows: First, parameters are set via touchscreen 3. Then, the pipeline is cleaned with pure water drawn by cleaning pump 11. Next, pesticide is drawn by liquid plunger pump 8. Then, the pesticide is diluted a second time by dilution plunger pump 9 and mixing plunger pump 10. Then, the diluted pesticide is sprayed into each test cell of test plate 15 through nozzle. Finally, ultra-high-definition camera 20 takes photos at regular intervals. The collected image data is then used by pest recognition model to calculate mortality rate and complete pesticide screening.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
