| 摘 要： | 随着化学农药成本的上涨及对环境问题的日益关注,要求生产出更加先进的喷雾设备以提高喷雾均匀性。喷杆式喷雾机在田间作业时,为保证施药效果,喷杆与作物冠层之间始终保持近似平行保持距适当距离,以避免喷杆倾斜刮伤作物,因而设计了一套喷杆式喷雾机喷杆高度在线调控系统。该系统采用超声波测距传感器和角度传感器相结合的方法,利用超声波测距传感器实时检测喷杆两端与植株冠层的距离并与系统设定的高度值进行比对来控制油缸的伸缩,角度传感器控制喷杆与水平面的倾斜角。本文给出了喷杆式喷雾机样机的总体结构,介绍了喷杆高度液压调节系统的组成和工作原理,并对喷杆高度在线调控系统的调节性能进行了场地和田间试验。

| Abstract: | The cost of chemicals and increasing concern with environmental pollution demand more sophisticated spraying-machines which are able to spray the liquid as uniformly as possible.In order to ensure the application effect and avoid spray boom scratching crops in the work process,spray boom and plant canopy need to be maintained approximately parallel and proper distance.An online control system of spray boom height was designed.The system adopts ultrasonic distance measuring sensor and angle sensor.The ultrasonic sensors detect the height from ground to spray boom and the controller calculates the direction and speed of hydraulic cylinders by comparing the set spray boom height with the actual spray boom height which was detected by ultrasonic sensors and the angle sensor is used to control the tilt angle of the spray boom.Then the controller sends out control signals of hydraulic cylinders to adjust spray boom height.The structure of boom sprayer and the composition and working principle of spray boom height hydraulic system were described The online control system of spray boom height was tested by ground test and field test. |
