自动移栽机双臂式取苗机构运动学试验分析研究

摘要

提出了一种双臂式取苗机构，简述了该机构的组成及工作原理，并介绍了其结构特点。为验证机构的工作稳定性，对其进行了运动学试验分析。试验结果表明：该机构在较低取苗速率情况下，机构工作稳定，能够满足自动取苗要求；但在较高取苗速度情况下，机构晃动较为明显，需对其进行进一步优化设计。%Presented a double arm picking seedling mechanism , sketched the constitution and working principle of this picking seedling mechanism , also introduced the structural features of this picking seedling mechanism .Did the kinemat-ic test to verify the working performance of this picking seedling mechanism .The test result shows:under the low picking seedling rate , the machine worked stabilized , the success rate of picking seedling was high , could satisfy the automatic picking seedling demanding .But under the high picking seedling rate , the machine waggled obviously , the optimal de-sign was needed .
