生物菌剂自动喷洒装置设计及定时控制系统研究

Research on the Design and Timed Control System of a Biological Bactericide Automatic Spraying Device

摘要: 为解决传统人工喷洒生物菌剂的诸多弊端，设计了一款生物菌剂自动喷洒装置。该装置结构，以架板与支撑架构成基础，移位机构与喷洒机构构成核心，储液箱与水泵等为辅助组件，以及以STM32单片机为核心的定时控制系统，可预设喷洒时间与间隔周期自动启停。通过移位与旋转喷洒协同，实现多方位无死角均匀喷洒，既提升了喷洒效率与菌剂利用率，又降低人工成本、避免人员受伤害，适用于农作物培育等农业自动化场景。

Abstract: To address the numerous drawbacks of traditional manual spraying of biological agents, an automatic biological agent spraying device was designed. The device features a structural framework composed of a base plate and support frame, with a core mechanism consisting of a shifting mechanism and a spraying mechanism. Auxiliary components include a liquid storage tank and a water pump, along with a timing control system centered on an STM32 microcontroller. It enables preset spraying schedules and automatic start-stop intervals. Through coordinated movement and rotation spraying, it achieves multi-directional, gap-free, and uniform application. This not only enhances spraying efficiency and agent utilization but also reduces labor costs and prevents personnel injuries, making it suitable for agricultural automation scenarios such as crop cultivation.
