8. The grain winnowing device with the buffering function according to claim 1, characterized in that supporting legs (3) are installed at the corners of the lower surface of the mounting plate (4).
9. The grain winnowing device with the buffering function according to any one of claims 1 to 8, characterized in that the use method thereof is as follows:
a. grains are fed into a pre-screening box (15) through a feeding hopper (14), and the grains are pre-screened through the work of a vibration motor (16);
b. after the pre-screening is finished, the pre-screening box (15) is rotated through the rotary air cylinder (13), and then the electric control door (11) and the feeding door (55) are opened, so that the pre-screened grains enter the winnowing box (6);
c. 2-3 minutes before the electric control door (11) and the feeding door (55) are opened, the air pump (53) is started to enable the air nozzle (54) to give out air, air flow blown out by the air nozzle (54) is used for winnowing the pre-screened grains, and the grain winnowing quality is improved;
d. the grains after winnowing fall into the grain receiving funnel (76), and the impact force between the grains and the grain receiving funnel (76) can be buffered through the deformation of the spring (72), so that the impact force on the grains is reduced, the probability of crushing the grains is reduced, and the use reliability of the device is improved; the silica gel pad (73) can also play a role in buffering, so that the probability of breakage of grains is further reduced;
e. after falling into the grain receiving funnel (76), the grains are discharged through the discharge pipe (75).
