Preferably, the curvature of the baffle is matched with the curvature of the arc-shaped plate, connecting holes are formed in the baffle and the arc-shaped plate, and two ends of the central rotating shaft are installed in the connecting holes.

According to the utility model, the rolling assembly arranged on the slideway base changes the sliding friction between the ore conveying chain structure and the sliding into rolling friction, so that the abrasion condition of the contacted structure caused by the sliding friction is reduced, and the service life of the whole structure is prolonged. The slideway base is of an arc-shaped structure, so that the contact area between a plurality of rolling assemblies and a chain is increased, and the stability of support is improved. The bearing increases the stability of rotation and prolongs the service life of the structure. The baffle that sets up carries out the quick connect shutoff to the tip of rolling element, convenient to detach.
