Design and experiment of cleaning mechanism for surplus grain at bungalow bottom
Due to the lack of professional cleaning equipment for collection of surplus grain at the bungalow bottom,in this article,with the limit of mechanical equipment working in the grain depot taken into consideration,efforts are made to a mechani-cal cleaning mechanism for surplus grain,which merely depends on the forward power.Based on the analysis of the current clean-ing mechanism,it is determined that a set of plate brushes should be used to gather and clean grain materials at the same time;the parameter design of key components is completed through theoretical calculation.According to the prototype test,when the material quantity is 1.25 kg/m2 and the advancing speed is 0.8 m/s,the cleaning rates of brown rice,corn kernels and soybeans are 47.2％,75.6％and 74.0％respectively.The cleaning mechanism for surplus grain works in the designed way,with the cleaning rate at the bungalow bottom more than 91％,which basically meets the requirement.This study provides reference for the research on cleaning mechanisms for grain materials.
