Grain conveyor with hidden take-up device
ActiveCN224198481Uprevent slidingFlexible adjustment of extension lengthConveyorsControl theoryMechanical engineering
The grain conveyor with the hidden take-up device comprises a grain conveyor body, and a plurality of take-up mechanisms used for winding power lines are arranged on one side of the grain conveyor body at intervals in the length direction of the grain conveyor body. The take-up mechanism comprises a fixing base fixedly connected with the grain conveyor body, a plurality of positioning rings arranged at the top of the fixing base at intervals in the width direction of the grain conveyor body, and a winding rod slidably connected into the positioning rings. A locking assembly is arranged at the top end of the fixing base, a plurality of locking parts matched with the locking assembly are arranged at the bottom of the winding rod in the length direction of the winding rod at intervals, and the locking assembly can be locked with the locking parts to limit sliding of the winding rod. The winding rod can be contained in the grain conveyor body in a sliding mode, the risk that people are stumbled and injured by collision is avoided, and the extending length of the winding rod can be adjusted according to the length of a power line.
