The invention discloses a tea green tedding machine, the structure of which is: a shaking machine driven by a power machine to shake up and down is arranged on the rack, the shaking output end of the shaking machine is fixed with a supporting plate, on which a screen unit is fixed through a plurality of springs, and a screen unit baffle is arranged around the screen unit. The shaking machine drives the supporting plate to bounce up and down and twitter the screen unit by the buffer of the spring, thus evenly dispersing the tea green all around, effectively replace manual operation, lowering the consumption of manpower and material resources and improving the working efficiency and the yield of tea green, with the tea green distributed evenly.
