Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a vehicle-mounted plant protection watering system. Background Technology

[0002] A vehicle-mounted plant protection sprinkler system refers to a sprinkler system installed on a vehicle for agricultural plant protection and irrigation. This system typically includes components such as a water tank, pump system, spray system, and control system. Such systems can significantly improve the efficiency of agricultural plant protection and irrigation, reduce manual labor intensity, and can be adapted to different crops by adjusting spraying parameters.

[0003] However, ordinary vehicle-mounted plant protection sprinkler systems are limited to simple watering functions, resulting in a relatively single function. Furthermore, in actual use, to effectively control pests and diseases and protect crop health, pesticides are often added to the sprinkler system for auxiliary spraying. The pesticide addition method in ordinary vehicle-mounted plant protection sprinkler systems is simple, and the large water tank volume makes it difficult to ensure the uniformity of pesticide addition. Considering the need to ensure stable operation and energy efficiency, we have developed a vehicle-mounted plant protection sprinkler system. Utility Model Content
