Rainproof chute mechanism and movable pouring trolley device

The utility model discloses a rainproof chute mechanism and a movable pouring trolley device, two ends of one side of a concrete chute are connected with support columns, the other side of the concrete chute is provided with a rainproof assembly, and the lower end of the concrete chute is provided with a traction assembly. When the forward and reverse motor rotates forwards, the winding reel can wind the steel wire rope and rewind the steel wire rope on the winding reel, meanwhile, the steel wire rope pulls down and unfolds the rainproof cloth through the hook at one end to cover the upper end of the concrete chute for shielding rain, and the roller rotates forwards synchronously so that the roller can lay down the rainproof cloth synchronously. When the rainproof cloth does not need to be used for preventing rain, the forward and reverse motor can be rotated reversely, the same roller and winding reel can rotate reversely synchronously, the winding reel can release the steel wire rope outwards, the roller re
