智能控制马铃薯精密播种机的研制
Research on the Intelligent Control of Potato Precision Planter
摘要
Abstract
In order to solve the problems of low seeding precision,difficult row spacing and amplitude adjustment of potato planter,this experiment installed intelligent row spacing devices on existing potato planter.The device of intelligent row spacing would auto-correct the electro-hydraulic servo valve to correct speed of hydraulic motor,when it detected the change in planter speed,etc.messages,so as to assure the qualification rate of row spacing within a permissible range.When the device detected more than one potato seed message or did not detect any message,it would adjust the conveyor belt and vibration intensity of potato seed bowl classifler.The result showed the actual missing rate ξls was 6.4％ ～7.9％ and resetting rate ξcs was 8.2％～ 10.1％,and the better allowed missing rate ξly was 6.0％～ 8.0％.This intelligent controlled potato precision drill could effectively improve the seeding accuracy and operation efficiency.At the same time,it also improved its adaptability to different areas and different potato varieties.关键词
