Description

Technical Field

[0001] This utility model relates to a portable pesticide spraying device, belonging to the technical field of pesticide spraying equipment. Background Technology

[0002] As a key link in agricultural production and industrial processing, spraying technology has evolved from simple to complex and from extensive to precise.

[0003] The earliest spraying equipment typically used a single nozzle, relying on manual hand-held operation or simple mechanical transmission. Such equipment was simple in structure and inexpensive, but it had drawbacks such as low operating efficiency, uneven application of pesticides, and high manual labor intensity, making it difficult to meet the needs of large-scale, high-quality operations.

[0004] To improve efficiency, boom sprayers with multiple nozzles have emerged. These devices typically mount multiple nozzles equidistantly on a rigid crossbar and are towed by a tractor or autonomous platform. This significantly improves operational efficiency and reduces labor costs per unit area, making it one of the mainstream spraying methods today. However, these traditional multi-nozzle sprayers are mostly complex in structure, expensive, and difficult to popularize in many impoverished areas. Furthermore, they are bulky, poorly adaptable, and ill-suited for operation on rugged, mountainous terrain. Utility Model Content
