存仓闭锁器用于开闭粉粒状物料存仓的排料孔以及调节卸出的物料流量,目前我国最常用的是平面式闭锁器,即螺旋闸门。它是通过丝杠传动来开启和关闭底板,从而控制卸料。它存在的缺点是:1.由于是人工转动手轮来调节丝杠,工人劳动强度较大,时间一长,粉尘进入丝母,转动起来更加困难; Locking device used to open and close the storage of silo granular material discharge hole and adjust the discharged material flow, the most commonly used in our country is a planar stopper, the screw gate.
