喷水施药一体化农用智能小车的设计

Design of an Integrated Spraying and Medication Agricultural Smart Cart

摘要: 随着农业装备现代化的发展，效率较低的人工作业方式已不适用于大规模生产的需要。针对上述现象，设计了一款喷水施药一体化农用智能小车。首先设计了智能农用小车的整体结构，采用减震弹簧和直流电机结合实现在崎岖土地的正常行走。同时，基于离心泵抽水技术设计了涡轮增压喷枪，可以自动调节喷洒范围，实现远距离喷射。其次，基于连杆结构和丝杆传动与升降机结合设计了可自主折叠、抬升的农药喷洒机构，可增大农药喷洒范围，提高施药效率。最后通过传感器等传感元件收集数据，结合PID控制算法和32 ARM单片机技术，实现小车自动驾驶，提高了农作物浇灌与施药的灵活性和便利性。喷水施药一体化农用智能小车作为一种实现自主规划路线、完成喷水、施药工作的农用小车，具有良好的应用前景和广泛的市场需求。

Abstract: With the development of agricultural equipment modernization, less efficient human work meth-ods are no longer suitable for the needs of mass production. In response to the above phenomenon, an integrated agricultural intelligent trolley with water spray and pesticide application is designed. Firstly, the overall structure of the intelligent agricultural trolley is designed, and the shock ab-sorption spring and DC motor are used to achieve normal walking on rough land. At the same time, a turbocharged spray gun is designed based on centrifugal pumping technology, which can auto-matically adjust the spraying range to achieve long-distance spraying. Secondly, based on the con-necting rod structure and the screw drive combined with the lift, the pesticide spraying mechanism that can be folded and lifted autonomously is designed, which can increase the range of pesticide spraying and improve the efficiency of pesticide application. Finally, the data is collected through sensors and other sensing components, combined with PID control algorithm and 32 ARM micro-controller technology, to realize the autonomous driving of the trolley, which improves the flexibil-ity and convenience of crop watering and pesticide application. As an agricultural trolley that real-izes independent planning of routes, completes water spraying and pesticide application, it has good application prospects and wide market demand.
