The conveying chain in the inner part adopts a double-plate chain structure, so that the defects that the chain is deviated due to uneven distribution of materials when the materials are conveyed in an inclined mode, and the abrasion of an inner wear-resistant layer is large can be effectively overcome.
The bottom plate of equipment is detachable construction, connects into the maintenance dismantlement of the later stage of being convenient for of a whole through bolt, nut, gasket and sealed glue.
The scraper and the chain-removing cutter at the head of the equipment are combined into a whole and are designed into adjustable devices. The position of the chain releasing component 24 can be adjusted on site according to actual needs, and continuous and stable operation of the equipment is guaranteed. Because of considering that the operational environment of equipment is mostly wet material, and has certain adhesion, this novel equipment has increased rubber material's cleaning device 27 at its head, and this design is easily changed and can effectively prevent the long-pending material problem of equipment that the material caused by reverse back-carrying.
Chain drives typically require a tensioner in order to avoid poor meshing and chain vibration due to excessive chain free length, as well as to increase the meshing wrap angle of the chain and sprocket in a chain drive.
Because the conveying chain is always under the action of tension in the operation process, after the conveying chain runs for a period of time, the length of the chain can be lengthened, and thus hidden troubles such as chain dropping and conveying efficiency reduction of the scraper conveyor can be caused.
The equipment is provided with a screw type tension device in the tail mechanism 5 to ensure continuous and stable operation of the equipment. The screw tensioning method comprises the following operation steps: after the equipment runs for a period of time, if the floating chain of the equipment is found, the screws on two sides need to be adjusted to move uniformly, so that the axis of the tail shaft is vertical to the central line of the conveyor. The time interval between tensioning the chain twice before and after can be determined empirically based on the use of the scraper conveyor. The surface of the adjusting screw rod should be kept clean, oiled and lubricated.
