Description

Technical Field

[0001] This utility model belongs to the field of smart agriculture technology, specifically, it relates to a new type of intelligent spraying vehicle for field management. Background Technology

[0002] The efficiency and precision of field management are increasingly important for agricultural production. Spraying, as a crucial part of field management, suffers from numerous drawbacks due to traditional manual methods. These include high labor intensity, harsh working conditions, significant health risks, low efficiency, and substantial pesticide waste. Furthermore, reliance on experience leads to uneven spraying, ultimately hindering crop yields. For taller crops such as corn, sorghum, and tall beans, commonly used sprayers cannot achieve even coverage. The large leaves, or the need for scaffolding, also make it difficult for workers to move around, impacting efficiency and making the work arduous. The spraying process itself is entirely dependent on human experience, easily resulting in uneven application.

[0003] Existing methods mostly employ semi-automatic or fully automatic spraying devices to replace manual spraying. Chinese utility model patent CN220211613U discloses an intelligent pesticide spraying robot, which solves the problems of uneven pesticide mixing, small spraying range, low work efficiency, and certain dangers to the health of spraying personnel caused by manual spraying. It can control the pesticide mixing ratio on-site by a lower-level machine or remotely by a higher-level machine, and carry out spraying operations according to a planned path. However, this spraying robot uses a tracked movement, which may damage crops when dealing with crops with narrow row spacing or tall seedlings. Furthermore, this spraying robot cannot mix solid and liquid pesticides, resulting in poor adaptability. Therefore, there is a need for a new type of intelligent pesticide spraying vehicle for field management that is highly adaptable and has high spraying efficiency. Utility Model Content

The liquid tank 2 is connected to the interior of the mixing tank 1 via a servo metering pump 9 and corresponding conveying pipes.
