technical field

The utility model relates to an injection-type variable-variable pesticide spraying device, in particular to a hanging-type direct-injection variable-variable pesticide spraying device.

Background technique

Plant protection is a very important link in the agricultural production process. Although the contribution of agricultural output to the world economy has been decreasing since the Industrial Revolution, the basic status of agricultural production as the basis for human survival has never been shaken.

The application of pesticides in the plant protection process has greatly reduced the damage of crops by diseases, insect pests and weeds, it can reduce the loss of food by about 15%, and has an irreplaceable role in the protection of vegetables, fruits and other economic crops. Therefore, the pesticide industry It has developed rapidly all over the world.

However, in the process of traditional agricultural pest and weed control, people mostly pay attention to how much yield can be increased by a certain agronomic measure. In order to achieve better spraying effect, farmers usually use the overall situation of the whole field to spray excessive To ensure the target area, and always blindly increase the amount of pesticides, or even mix the pesticides at will, increase the number of pesticides, so that the amount of pesticides continues to rise. This has produced a series of negative effects: (1) causing waste of resources and environmental pollution; (2) causing pesticide residues in agricultural products such as food and vegetables, and bringing huge losses to the economy; (3) causing direct or Indirect poisoning; (4) causing an increase in the resistance of pests and weeds, and at the same time reducing their natural enemies and beneficial insects, making the agricultural ecosystem face the danger of imbalance.

Variable spraying technology can accurately control the amount of pesticide spraying according to the severity of pests and weeds, which is of great significance to improving the utilization rate of pesticides, reducing the pollution of pesticides to the environment and reducing pesticide residues in agricultural products. At the same time, with the popularization and promotion of remote sensing technology (Remote sensing, referred to as RS), geographic information system (Geography information system, referred to as GIS) and global positioning system (Globa positioning system, referred to as GPS) technology, agricultural machinery can achieve precise positioning, And through the relevant software to analyze the demand for pesticides of the crops where they are located during the operation process, the analyzed demand for pesticides is then converted into control signals to control various operating mechanisms and finally realize the precise spraying of pesticides.

Moreover, with the development of China's economy and the reduction of agricultural population, the farmland collective management mode is the general trend. It has also begun to be applied all over the country, but usually the spraying amount is adjusted before the machine goes down to the ground (generally, the spraying amount is set according to the most severe area). The spraying amount does not change during the entire operation process.
