Description

Technical Field

[0001] The invention relates to the technical field of agricultural pest control, and in particular to a pesticide spraying device for agricultural pest control. Background Art

[0002] Agricultural modernization refers to the process and means of transformation from traditional agriculture to modern agriculture. In this process, agriculture is increasingly armed with modern industry, modern science and technology, and modern economic management methods, so that agricultural productivity is increasingly transformed from traditional agriculture to the world's advanced level of agriculture. Crops are often attacked by various diseases, insects, and weeds during their growth, threatening the healthy growth of crops, as well as their yield and quality. In serious cases, there may even be no harvest. Pest and disease control has become an indispensable and important part of the agricultural production process. At present, the main methods of pest and disease control include biological control, physical control, and chemical control. Among them, chemical pesticide control is the fastest and most effective method. Chemical pesticide control mainly relies on pesticide dilution spray, and pesticide spraying is an effective means of plant protection.

[0003] There are many kinds of pesticide spraying equipment currently in use, mainly drones, large mechanical equipment, small sprayers, etc. Drones are more suitable for use in places with wide areas and group prevention and control. The advantage is high efficiency, but the disadvantage is high initial investment cost, the liquid drift is relatively far, and it is easy to cause pesticide pollution to crops in adjacent plots. However, drones, large mechanical equipment, small sprayers, etc. all spray on the upper surface of crops, and cannot spray on the roots and stems of crops, resulting in incomplete spraying, especially when using drugs to kill insects, it is impossible to kill insects on the roots and stems or below the leaves.
