It is a continuous and efficient mechanical slag removing equipment, and is often used in sorting or solid-liquid separation occasions. For example, boiler slag removal system, river sand excavation system and the like. In chain transmission, because the chain transmission load is large, the chain is prone to stretch and deformation in use, and chain slack phenomenon is caused, which is prone to cause repeated wear of the chain, and even chain jump and the like. In order to prevent the chain from appearing slack or derailing, workers often set a tensioning wheel on the side of the chain, and keep the chain tension by manually adjusting the tensioning wheel to ensure the stability of the chain transmission, but workers need to pay attention to the running status of the chain at all times, which increases the labor intensity.
