  • Publication number: 20180334329
    Abstract: A guide that fits over a paddle link in a paddle-type elevator in a harvester combine grain elevator. The plastic guide provides a wide, low-friction surface that rides on the intermediate wall of a grain elevator, thereby keeping the paddle links from rubbing against and causing wear to the intermediate wall. The guide also serves to inhibit the paddle from tipping back, thereby preventing the concentration of force by one corner of a paddle link against the intermediate wall. The guide also helps maintain the correct orientation of flexible paddle against the inside of the elevator housing, thereby inhibiting the paddle from tipping back and leaking grain back into the upward path of the conveyor. The plastic guide also reduces noise caused by the metal parts of a paddle-type elevator from coming into contact.
