Shield constructs machine band conveyer's inclined to one side device of preventing

The utility model discloses a shield constructs machine band conveyer's inclined to one side device of preventing, preventing inclined to one side edger roll and the no material gyration belt that sets up in nos material gyration belt both sides including the material conveyor belt who sets up in material conveyor belt both sides and preventing inclined to one side edger roll, material conveyor belt prevents inclined to one side edger roll and installs on the fixed steel sheet of edger roll that the fixed steel sheet of edger roll is fixed on belt feeder frame ear seat, and no material turns round the belt to be prevented inclined to one side edger roll and install in the belt feeder frame. In case band conveyer's belt off tracking, material conveyor belt prevent inclined to one side edger roll and nos material gyration belt and prevent inclined to one side edger roll and will rectify a deviation, its radial thrust is that material conveyor belt prevents inclined to one side edger roll and nos material gyrati
