Double-layer winnowing industrial hemp flower, leaf and seed separator

The invention discloses a double-layer winnowing industrial hemp flower, leaf and seed separator, relates to the technical field of agricultural machinery, and solves the problems that an existing screening machine is poor in screening effect, high in motor power, energy-wasting, the same in vibrating screen frequency, unobvious in screening effect, easy to block a feed port of the machine and the like. Small air volume corresponds to gaps of the first screen and the second screen, large air volume corresponds to gaps of the second screen and the third screen, due to the fact that the mass of the objects is different, under the blowing effect of the draught fan, the throwing effect of different distances is achieved for different objects, the multiple filter screens can save the procedure of manually selecting impurities, a large amount of manpower is saved, and the production efficiency is improved. The powder and mature grains with different diameters, such as 0.5 cm powder, finer powder, coarsely screened
