Then the grains are discharged through the through groove and the discharge frame. While the two pressing components are working, the two lifting components work to drive the lifting platform to reciprocate on the two lifting rails, and then the lifting platform drives the agglomerated grains on the second filter net to vibrate with the reciprocating lifting, so that the two pressing components can compress all agglomerated grains.
