The invention relates to a light-gathering tedding device for tea. The light-gathering tedding device comprises a tedding support plate, wherein a mounting cylinder is welded to the middle of the upper end surface of the tedding support plate; an annular limiting groove is mounted on the upper end surface of the tedding support plate; four limiting columns are uniformly mounted inside the annular limiting groove along the axial direction in a slide fit manner; a fixing ring is welded to the top ends of the four limiting columns; an inner gear ring is arranged on the inner wall of the fixing ring, and meshed with four drive branched chains along the axial direction; the lower ends of the four drive branched chains are all mounted on the tedding support plate; the four drive branched chains are uniformly meshed with the inner gear ring, so that the transmission force of the four drive branched chains on the inner gear ring is uniform, the transmission effect is good, the inner gear ring is driven by the four drive branched chains to rotate, and the fixing ring is driven by the inner gear ring to rotate; and under the limiting and supporting assistant action of the four drive branched chains and the annual limiting groove, the fixing ring can rotate stably. By adoption of the light-gathering tedding device provided by the invention, the automatic tea tedding function can be achieved.
