便携式双刀片电动果园采收装置设计

目的]解决华南丘陵山区水果摘采机械化难度大的问题。方法]采用计算机模拟设计了一款便携式双刀片电动果园采收机具。首先通过建立力学模型的方式，论证了方案的可行性，排除了一次剪切不成功的情况；其次对机具的硬件选择和电路控制，计算机工作程序等进行了设计。结果]设计的双刀片机械辅助果园采收机具，由两片切割刀片，两台直流伺服电机、可伸缩支架杆等组成，工作时刀片始终在水果筐范围内移动，不会出现因为刀片移动到筐外而损伤其余未摘水果的情况，可有效降低因采收机具而产生的产量损失。结论]该设计方案通过切割力分析验证，不存在一次切割不成功的情况；该机具搭栽的直流电机，选用12V／6AH电池，每次可工作10h，可满足山地工作需求。

Design of Portable Double Blade Electric Orchard Recovery Device

Objective ] To solve the problems in fruit picker mechanization in the hilly region of southern China. Method ] A portable double blade electric orchard recovery device was designed using computer simulation. First, we set up a model of physics to prove the feasibility of this project and also prove that the blade can cut off the branch in one time. Then we discuss the design of circuitry and software with this project. Result] The designed recovery device consists of double blades, two DC servo motor, the telescopic support rod. Conclusion] The design scheme was verified by cutting force; the DC motor used 12V/6AH battery, which can work 10 h each time and satisfy mountain work demands.
