Therefore, the wind power in the light impurity winnowing channel 33 is larger closer to the light impurity outlet 37, so that the light impurity sieve plate 312 pushes the slightly heavy impurities such as short stalks, small weeds and the like which are not sieved by the large impurity sieve plate 311 to the light impurity outlet 37 under the synergistic action of the airflow and the small impurity sieve plate 312 in the vibrating process, and the wind power is larger closer to the light impurity outlet, so that the impurities can be separated and blown out, and the winnowing effect of the winnowing machine is better. Similarly, in order to conveniently discharge the impurities such as the heavier stones screened on the specific gravity screening table, the cross-sectional area of the end of the specific gravity screening table connected with the stone outlet is gradually reduced from inside to outside. Referring to fig. 4, the small trash screen 312 is a fish scale hole screen, and the fish scale holes 3121 are disposed toward the light trash outlet 37. Compare ordinary sieve like this, the vibration of fish scale hole sieve is selected separately the effect better, and can guide the wind current direction.
