螺旋输送机俗称绞龙，适用于颗粒或粉状物料的水平输送，倾斜输送，垂直输送等形式。输送距离根据畸形不同而不同，一般从2米到70米。
Spiral conveyor, commonly known as winch, is suitable for horizontal, inclined and vertical transportation of granular or powdery materials. Transport distance varies according to deformity, generally from 2 meters to 70 meters.
输送原理：旋转的螺旋叶片将物料推移而进行螺旋输送机输送。使物料不与螺旋输送机叶片一起旋转的力是物料自身重量和螺旋输送机机壳对物料的摩擦阻力。
Conveying Principle: Rotating screw blade pushes material to convey by screw conveyor. The force that makes the material not rotate with the blade of the screw conveyor is the weight of the material itself and the friction resistance of the shell of the screw conveyor to the material.
结构特点：螺旋输送机旋转轴上焊有螺旋叶片，叶片的面型根据输送物料的不同有实体面型、带式面型、叶片面型等型式。螺旋输送机的螺旋轴在物料运动方向的终端有止推轴承以随物料给螺旋的轴向反力，在机长较长时，应加中间吊挂轴承。双螺旋输送机就是有两根分别焊有旋转叶片的旋转轴的螺旋输送机。说白了，就是把两个螺旋输送机有机的结合在一起，组成一台螺旋输送机。螺旋输送机旋转轴的旋向，决定了物料的输送方向，但一般螺旋输送机在设计时都是按照单项输送来设计旋转叶片的。当反向输送时，会大大降低输送机的使用寿命。
Structural characteristics: spiral blades are welded on the rotating shaft of the screw conveyor. The blade surface types are solid surface, belt surface and blade surface according to the different materials conveyed. The screw shaft of screw conveyor has thrust bearing at the end of the material movement direction to give the axial reaction force to the screw along with the material. When the length is long, choufangg.89ix.comchuwuqit.37ix.com.cnbiaozhiz.37ix.com.cnqima.37ix.com.cnchuwuqi.37ix.com.cn chuguo.37ix.com.cnthe bearing should be suspended in the middle. Double screw conveyor is a screw conveyor with two rotating axes respectively welded with rotating blades. To put it plainly, it is to combine two screw conveyors organically to form a screw conveyor. The rotating direction of the rotating shaft of the screw conveyor determines the direction of material conveying, but the general design of the screw conveyor is based on the single conveyor to design the rotating blade. When conveying in reverse, the service life of conveyor will be greatly reduced.
