The screening shell 1, the lower screen 8 and the upper screen 9 are made of light aluminum alloy material, and the spring piece 25 is made of high-strength and elastic material.

[0033] Working principle and use process of the utility model: after the utility model is installed, first pour an appropriate amount of corn seeds through the top of the screening shell 1 into the interior of the upper screen 9, and then start the first motor 4 to rotate and drive the two sets of rotating shafts 5 to rotate, the rotating shafts 5 rotate and drive the rotating plate 6 to rotate, the rotating plate 6 rotates and drives the long swing rod 7 to swing through the pin shaft, because there are multiple sets of spring pieces 25 between the lower screen 8 and the upper screen 9, and there are also multiple sets of spring pieces 25 between the upper screen 9 and the screening shell 1, at this time, the long swing rod 7 moves through the pin shaft to pull the lower screen 8 to shake, and the lower screen 8 drives the upper screen 9 to shake through the spring pieces 25, so that the corn seeds can be screened, and the solid impurities contained in the seeds can be filtered, which is convenient for subsequent drying treatment;

[0034] When the rotating shaft 5 is started to rotate, the second motor 10 is started to drive the rotating rod 11 to rotate. The rotating rod 11 rotates and slides in the slide groove inside the fixed slide groove 12 through the lever, which can drive the fixed slide groove 12 to move left and right. The movement of the fixed slide groove 12 can drive the rack 13 to reciprocate left and right. The meshing transmission of the rack 13 drives the gear 14 to perform forward and reverse rotation. The rotation of the gear 14 can stir the corn seeds that have fallen into the stirring bin 17 through the stirring blades 16 on the surface of the stirring rod 15. At the same time, the dryer 26 can dry the seeds being stirred in the stirring bin 17. Since the stirring rod 15 is in forward and reverse motion, the seeds will not be continuously stirred, which can avoid damage to the epidermis of the seeds and affect the quality of seed drying.

[0035] While the stirring rod 15 rotates forward and backward, it can drive the fixed rod 21 to rotate. The rotation of the fixed rod 21 can drive the fixed block 24 at one end to rotate. The rotation of the fixed block 24 can intermittently push the sliding column 22 to move back and forth inside the stirring bin 17. The movement of the sliding column 22 can drive multiple groups of dial plates 23 to move inside the stirring bin 17. At this time, the movement of the dial plates 23 can assist the stirring blades 16 to shake the corn seeds inside the stirring bin 17, which can prevent the seeds from caking during the drying process, affecting the drying quality, and the drying efficiency is high;

[0036] At the same time, when the lower sieve 8 and the upper sieve 9 screen the seeds, the rotation of the stirring rod 15 will drive the belt 18 to rotate through the pulley. The belt 18 drives the fan blade 20 to rotate forward and backward through the pulley. When the fan blade 20 rotates forward, it can blow up the dust and impurities in the seeds being screened, and then the two adsorption nets 2 adsorb them. When the fan blade 20 rotates backward, it can discharge part of the hot air generated during the drying of the internal seeds through the through holes on the surface of the exhaust plate 19, preventing the temperature inside the screening shell 1 from being too high and affecting the drying effect of the seeds.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
