The course of work of the present utility model is: seed to be selected is put into feed hopper, under the effect of charging blower fan, in the referred bucket of all seeds, during by the charging air channel, wherein all light assorted air inlets by the selection by winnowing blower fan are drawn onto light assorted outlet and discharge at seed; Seed in the bucket flows to earlier on the pore sieve plate of screening washer by the discharging opening of its bottom, the pore sieve plate is driven by motor, eccentric wheel, spring and does upper and lower vibration, seed rolls on the pore sieve plate from top to bottom, wherein differs bigger carefully mixing with seed sizes and is separated under the pore sieve plate; Seed on the inflow gross porosity sieve plate falls into the seed export under the compass screen surface, because the gross porosity sieve plate is covered by the gravity preparation air channel, wind passes the material on the compass screen surface from the compass screen surface below, with seed more approaching useless material on size, weight, as bud paddy, infected seed etc., suction by the gravity preparation blower fan holds, and accompanys or follow big impurity, stone etc. and progressively rolls in the groove on sieve plate both sides and the low side frame, and discharge through sediment flushing outlet, impurity outlet.

As further improvement of the utility model,, can observe the seed selection process in charging air channel, the gravity preparation air channel, to adjust the wind-force size of each blower fan on the charging air channel, on the gravity preparation air channel and be provided with corresponding window on the shell;

As further improvement of the utility model, base plate in light assorted outlet, seed export, impurity exit all is obliquely installed, in outlet, be provided with valve, the upper end of valve is installed on the biside plate of outlet by rotating shaft, the lower end contacts with the base plate of outlet, and with the angle of base plate less than 90 °, when seed or impurity are accumulated in the exit when a certain amount of, weight by himself is backed down valve, automatically discharging outward.

In sum, seed purifier of the present utility model combines selection by winnowing, screening, gravity preparation together, has good impurity removing effect, takes up an area of less, operating personnel are few and advantage of high production efficiency.
