The invention discloses a sun-drying frame for tea leaf withering. The sun-drying frame comprises connecting frames and ceilings, wherein the ceilings are movably connected to the top ends of the connecting frames; the connecting frames comprise connecting rods I, connecting rods II, connecting rods III, connecting rods IV and supporting rods; two connecting rods I and two connecting rods II are correspondingly arranged on the left and right sides of each connecting frame; and the connecting rods III and the connecting rods IV are movably connected in a crossed manner. The sun-drying frame disclosed by the invention has the beneficial effects of being simple in structure and convenient to use; when in use, the sun-drying frame is clean and sanitary; fresh leaves of a tea tree are preventedfrom falling to the ground, and then domestic animals such as chickens and dogs are prevented from treading on the tea leaves; spreading and sun-drying nets are high in ventilation performance and air permeability, and then the tea leaf withering process is uniform and fast; under the situation of strong light, the ceilings can be lowered to a certain extent and used for blocking the sun; and when the tea leaves cannot be timely taken into a room in the weather of sudden rain, the ceilings can be lowered so as to keep out the rain, and then the fresh leaves of the tea tree can be effectivelyprevented from being withered excessively or getting wet in the rain.
