Abstract
The invention provides a shunting and uniform distribution device used for a roll screen, and relates to shunting and uniform distribution devices. The device comprises a coal conveying system (1), the roll screen (5) and a shunting and uniform distribution device body. The shunting and uniform distribution device body comprises a rolling shaft (2), a motor (6), thrust bearings (3), a flow guide blade A (4) and a flow guide blade B (9). The flow guide blade A rotating leftwards or rightwards is arranged on the outer circumference between the center of the rolling shaft and one end of the rolling shaft. The flow guide blade B rotating opposite to the flow guide blade A is arranged on the outer circumference between the center of the rolling shaft and the other end of the rolling shaft. The motor is fixedly connected with one end of the rolling shaft through a coupler (7). One thrust bearing (3) is arranged in the position, close to the coupler, on the rolling shaft. The other thrust bearing is arranged at the other end of the rolling shaft. The phenomenon that coal is little or no coals exist on the two sides of a screen bed is avoided, conveyed coal is evenly distributed on the roll screen, and screening efficiency is effectively improved.
