振动输送机主要用来输送粒状物料,它们利用许多弹簧支承着或者悬挂起来。振动槽通过一些连杆、偏心重或电磁铁产生一种小振幅的高频振动,由轻微的跳动输送物料。按照振动槽的长度、输送速度和振动的特征对比了不同的驱动方式。振动输送机设计的特征值是动物料系数。这系数表明槽体最大垂直加速度与重力常数之比。振动系统一般调谐在接近共振的低于临界状态,因此变化槽体负荷对于输送速度只有轻微的影响。输送速度决定于激振频率、槽体运动角度、抛掷时间与接触时间之比,同时兼顾物料性质、加载高度及槽体倾角。正确的输送机设计还应根据操作条件确定阻尼常数和荷载的物料结合系数。
Vibratory conveyors are mainly used to transport granular materials, which are supported or suspended by a number of springs. Vibrating slots produce a low-amplitude, high-frequency vibration through links, eccentric weights or electromagnets that convey material with slight jerks. In accordance with the length of the vibration tank, conveying speed and vibration characteristics compared to different driving methods. The characteristic value of vibration conveyor design is the coefficient of animal feed. This coefficient shows the maximum vertical tank acceleration and gravity ratio. Vibratory systems are generally tuned to sub-critical conditions close to resonance, so changing the tank load has only a slight effect on transport speed. Transmission speed depends on the excitation frequency, tank movement angle, throwing time and contact time ratio, taking into account the nature of the material, loading height and tilt angle. Correct conveyor design should also be based on operating conditions to determine the damping coefficient of the load constant and the material combination.
