The invention discloses a door-shaped movable spraying frame. The door-shaped movable spraying frame comprises a door-shaped frame body, bottom rails and rotary connection frames. The top surface of each rotary connection frame is provided with a connection screw joint portion which is screwed to the bottom surface of a top crossbeam of the door-shaped frame body, and the rotary connection frames are uniformly distributed on the bottom surface of the top crossbeam of the door-shaped frame body. Moving blocks are fixed to the bottom surface of the door-shaped frame body and mounted in the bottom rails, moving racks are fixed to the outer side walls of the bottom guide rails, moving motors are fixed onto the moving blocks respectively, a transverse moving gear is fixed to an output shaft of each moving motor and meshed with a transmission gear hinged to the side wall of the corresponding moving block, and each transmission gear is meshed with the corresponding moving rack. A connection pipe is fixed to the top surface of the top crossbeam of the door-shaped frame body. The door-shaped movable spraying frame is capable of moving horizontally along the bottom rails, a plurality of nozzles arranged on the door-shaped movable spraying frame are capable of rotating horizontally and adjustable in vertical angle, and accordingly different spraying requirements can be met, and spraying effects are improved.
