The utility model discloses a combined cleaning
sieve, including box body and
sieve, the inside parallel installation of box body has two slide rods, and the top of two slide rods is provided with
sieve, in the utility model, through first
motor drive main shaft rotation, main shaft helps
transmission belt synchronous drive two auxiliary shafts rotation, makes main shaft and auxiliary shaft bottom's stirring
impeller simultaneously rotates on the screen of sieve, carries out stirring, and turns over to the grain, makes the upper layer and lower layer grain constantly exchanges position, lets all grain can receive
screening effect evenly, avoided the screening
lag that grain accumulation caused, simultaneously, second motor drives disc
cam rotation, and disc
cam and sieve left side wall's concave resistance block interact, and cooperate the spring's elastic reset force on sieve right side wall guide rod, makes sieve through slide sleeve on two slide rods reciprocating sliding, and sieve's reciprocating sliding has increased the
relative motion frequency of grain and screen, and the speed of
small particle sundries through screen has been accelerated.
