Description

Technical Field

[0001] The invention relates to the technical field of spraying effect testing, and in particular to a spraying effect testing device of a soybean-corn composite planting spraying plant protection machine. Background Art

[0002] Plant protection operations can effectively prevent and control pests and diseases, and are an important means to ensure my country's food security and improve the quality and yield of agricultural products. Traditional ground plant protection equipment has disadvantages such as low operating efficiency and large amount of pesticides. There are many types of plant protection machines. Due to the different dosage forms and crop types of pesticides, as well as different spraying methods, plant protection machines are also diverse; among them, drug spraying drones are a type of plant protection machine. The use of plant protection drones for aerial spraying can greatly increase the operating speed and reduce the amount of pesticides used. In the soybean-corn strip composite planting, it has the advantages of not being restricted by the growth of corn crops and being able to operate at the right time. However, the uncontrollable random wind field in the environment, the rotor downwash flow field, and the mutual coupling between crops make it easy for light-weight and small-size droplets to move to non-target areas and deposit, resulting in droplet drift and uneven distribution of droplets in the operating field and crops.

[0003] For example, the variable spraying effect test device for agricultural spraying equipment disclosed in the patent with announcement number CN113252379B can test the spraying effect by spraying paint on white paper. However, during the test, since the white paper is fixed, when there is too much paint on the white paper, the white paper is completely soaked with paint, and it is impossible to accurately judge the amount of paint, and further, it is impossible to judge the uniformity of the spraying, which reduces the accuracy and effect of the test. Therefore, it is urgent to design a spraying effect test device for a soybean-corn composite planting sprayer. Summary of the invention
