Technical Field
[0001] The utility model relates to the technical field of pesticide spraying devices, in particular to a pesticide spraying device with a nozzle having both movement and rotation functions. Background Art
[0002] China has a large population, and the area of cultivated land is decreasing year by year. In the future, the demand for food will gradually increase. It is necessary to increase the per-acre yield of cultivated land and minimize the losses caused by pests and diseases to ensure the country's food supply. In addition, the labor force in rural areas is getting smaller and smaller. In order to improve the production efficiency of agricultural operations, agricultural mechanization has become the most respected research hotspot. Due to the late start of agricultural operation machinery research in my country, complete mechanization and automation have not been achieved, and the lack of efficient and labor-saving agricultural equipment and technology has restricted the development of agricultural mechanization technology in my country. With the continuous expansion of my country's farmland planting area, the requirements for large-scale development and standardized management of farmland are increasing, and the importance of agricultural mechanization is becoming increasingly prominent. Improving the production efficiency of agricultural operations, promoting sustainable agricultural development, and liberating productivity have become issues that we need to actively solve.
[0003] Insect pests in my country have great migration and mobility, and pest control is relatively complicated. At present, due to the lack of relevant knowledge of pesticide spraying by many farmers, the effect of pesticide spraying is not ideal, and if farmers do not clean in time after spraying pesticides, it will cause harm to the body and pose a safety hazard. Traditional pesticide spraying technology is mainly handheld spray, which is inefficient, harmful to operators, and difficult to meet the needs of large-scale operations. Traditional pesticide spraying uses pressure to change the amount of pesticide sprayed. When the pressure changes, the droplet particle size will change, resulting in uneven pesticide spraying. In addition, the previous pesticide configuration was mainly based on the observation of crops by the pesticide applicator and was set by itself, lacking certain scientific support. Spraying with aircraft or large equipment requires a large amount of pesticide and a single coverage area, which will lead to waste of pesticides and pollution of surrounding land. People are increasingly aware of the negative impact of pesticide spraying on the environment, and urgently need new technologies and methods to reduce the impact of pesticide spraying on the environment, so as to increase agricultural product output and reduce input losses. The development of regionalization, specialization and socialization of agriculture has played a great role in the rational use of natural resources, the adoption of advanced science and technology and the improvement of production efficiency.
