一种板栗自动收获剥苞机的设计

Design of a chestnut autonomic harvesting and husking machine

为解决传统板栗(Castanea mollissima BL.)生产中收集、剥苞两步人力劳动大、生产效率低、传统机械落后等问题,设计了由树莓派3B+主控板为控制核心,Arduino为开发平台,蓄电池和电机为动力,实现板栗自动收获和剥苞的板栗自动收获剥苞机。板栗自动收获剥苞机由控制系统实现在板栗园内的自动循迹行走;经鬃毛刷转动可实现板栗的捡拾收集,捡拾精度高;板栗经由双辊轮转动所带动的其上以聚四氟软管刀片的挤压实现剥苞,板栗受损率低、剥苞效率高。该整机结构简单,实用性强,以期为进一步提高板栗生产效率提供参考。

In order to solve the underlying problems of intensive manual labour,low working efficiency and backward traditional machinery in harvesting and husking process of chestnut production,a chestnut autonomic harvesting and husking machine with Raspberry Pi 3 Model B+as control core,Arduino as development platform and battery and electric motor as power was designed.The designed chestnut autonomic harvesting and husking machine can realize autonomic track walking in the chestnut orchard by the control system;the harvest of chestnut can be realized by the rotation of bristle brush with high harvesting accuracy;chestnut husk is removed by the extrusion of PTFE hoses driven by the rotation of twin rollers.The whole machine has simple structure and strong practicability,which can provide suggestions for further improving the production efficiency of chestnut.
