The internal lead screw at the tail of the machine is easily blocked by coal slime, causing the chain at the tail of the machine to loosen. The operator needs to tighten the chain, which is extremely laborious. At present, when the slideway at the tail of the shallow trough sorter is tensioned, it needs to be tightened to prevent the chain from loosening. However, the tightening effect of the existing equipment is not good, which easily causes the lead screw 6 to rotate in the opposite direction under force.
