水下收草装置的设计

Design of the Harvesting Aquatic Weed Device

比较了几种水草收割方式,确认机械治理是最理想的方式。通过仿人手设计"手爪",利用凸轮实现"手爪"的抓紧和放松,分析链传动的多边形效应,通过振动抖落水草实现收割。与其他类似的水草收割装置进行了性能分析和比较。结果表明,水下收草装置效率高、成本低、减轻人体劳动,能够实现水草的连根拔起,但又不破坏环境,大大降低了次年该类水草的疯长。

The mechanical management is the best way to manage aquatic weed through comparisons of some managing methods. In order to harvest aquatic weed, claw is designed by imitating human＇s hands, The claw can grasp aquatic weed tightly and loosen easily through the cam gear. In order to shake off aquatie weed from the claw, the chain polygon effect is analyzed. By analyzing and discussing with other similar plants harvesting device, the results show that the efficiency of the device is high and the cost is low. In addition, the device can harvest aquatic weed with its roots which reduces the number of weeds growing in the next year.
