为有效减少农村劳动力不足对茶产业发展造成的较大影响,提高农药、化肥的利用率来减少环境污染,设计了一种茶园遥控式静电喷药施肥机。主要由机架、动力、喷药系统、施肥系统、控制系统等组成,可手动式和无线遥控行走。48V直流无刷电机实施行走和施肥及12V直流叶片泵实施喷药;采用容量式调节施肥量,并完成浅施肥和覆土;采用茶树冠仿形喷杆和高压静电实施喷雾。试验结果得出该机能较好地完成施肥施药,明显提高农药叶面雾滴沉积量,是一种有发展前景的机型。

In order to decrease the more influence on tea production development for the shortage of labor, and increase the utilization of pesticide and fertilization to reduce the environmental pollution, a remote controlling machine for electrostatic spraying and fertilizing in tea garden was investigated. The machine was mainly made of frame, power, spraying system, fertilizing system and controlling system, which held the manual and remote controlling operations. The machine’s driving and fertilizing function adopted 48 Voltage direct current brushless motor and the spraying 12 Voltage direct current vane pump. It used the capacity adjustment shallow fertilization and can be soil covered. The tea plant’s profile modeling spraying pole and high voltage electrostatic electricity were utilized to realize spraying. Experimental results showed that the machine could complete the fertilization and spraying preferably, and improved the fogdrop deposition on the leaf obviously. The machine is prosperous in the future.
