The invention discloses tea production equipment and particularly relates to a tea carding machine capable of realizing tea discharge conveniently. The tea carding machine comprises a rack, a pot rack reciprocating on the rack and a grooved pot mounted on the pot rack, wherein the grooved pot comprises a plurality of U-shaped grooves, each U-shaped groove comprises two side plates and two arc plates hinged to the lower ends of the side plates, and the two arc plates are closed to constitute the bottom of the U-shaped groove; a control mechanism for controlling opening and closing of the arc plates is arranged on the rack and comprises Y-shaped support columns and hydraulic columns connected with lower parts of the Y-shaped support columns, each Y-shaped support column comprises three supports, the three supports of each Y-shaped support column are hinged to the same hinged point, two upward supports of each Y-shaped support column are hinged with two opposite arc plates respectively, and the length sum of the two upward supports is larger than an interval between the adjacent hinged points when the arc plates are in the closed state. When the tea carding machine is used for tea discharge, the arc plates at the bottom of the U-shaped grooves are opened, tea drops on a conveying belt below the arc plates, and accordingly, the tea discharge is realized.
