苏联某钾盐矿采用一种具有下部运载分支的皮带运输机,避免了物料的撒溶,其效果显著。附图所示为该种皮带运输机的卸载和装载系统。其改造方式如下:驱动装置、驱动辊筒、第一偏转轮、拉紧轮和拉紧锤以及框架和工作托辊都保留不变,加装了第二、第三、第四偏转轮以及犁形清料刮板。之后,重新拉紧皮带,安装集料袋和环状漏口。该皮带运输机工作方式:物料落到下部运载皮带分支上,并由该皮带分支送往卸载漏口。皮带绕过辊简,使物料落向卸载漏口,并以漏口卸到下一个皮带运输机上。由于各偏转轮的作用,使皮带表 A potassium salt mine in the Soviet Union uses a belt conveyor with a lower carrying branch to avoid spreading of the material, which has a significant effect. The drawings show the system for unloading and loading the belt conveyor. The transformation is as follows: the driving device, the driving roller, the first deflection wheel, the tensioning wheel and the tensioning hammer as well as the frame and the working roller remain the same, the second, the third and the fourth deflection wheels are added, and the plow Shape clear scraper. After that, re-tension the belt, install the bag and the annular leakage. The belt conveyor work: the material fell on the lower part of the carrying belt, and by the belt branch to the unloading leak. The belt is passed around the roller so that the material falls into the unloading port and is unloaded to the next belt conveyor. As a result of the deflection wheel, make the strap table
