摘　　要：阐述了双直溜槽与双螺旋溜槽连接式装粮器的结构设计原理和原则。绘出了双直溜槽与双螺旋溜槽连接式装粮器结构示意图,依据摩擦理论和功能原理,由给定的粮食入口速度、出口速度、粮食流量,粮食与溜管的摩擦系数,设计出直溜槽、螺旋溜槽与水平面倾角α,直溜槽、螺旋溜槽的长度S1、S2,直溜槽、螺旋溜槽半圆截面半径γ。Principle on grain loading device of connection mode of double straight chutes and double spiral chutes are stated. Diagrammatic sketch of the grain loading device of connection mode of double straight chutes and double spiral chutes are drawn. According to frictional theory and principle of work and power, under given condition on entrance velocity of grain, outlet velocity of grain, rate of flow of grain and coefficient of friction of the chutes and grain, dip angle of the straight chute and the spiral chute for horizontal plane , length of the straight chute , length of the spiral chute s2 and radius of semi--circular section of the straight chute and the spiral chute γ are designed.
