To achieve these goals, the technical solution of the utility model is as follows:

A kind of grain cleaning unit, comprise screening plant, pneumatic separation device and two belts promote conveyer, it is characterized in that first belt promotes the feed hopper of the blanking termination screening plant of conveyer, described screening plant is a drum type brake cleaning sieve, drum type brake cleaning sieve one end top is provided with feed hopper, in the drum type brake cleaning sieve drum sieve is housed, drum sieve one termination feed hopper, the other end is connected to big assorted outlet, there is discharging opening the drum sieve below, the discharging opening of drum type brake cleaning sieve connects second belt and promotes the conveyer feed end, second belt promotes the feeding hopper of the blanking termination pneumatic separation device of conveyer, described pneumatic separation device is electronic air blast winnowing machine, the mouth of putting out cereal below the electronic air blast winnowing machine, and the sidepiece of winnowing machine has little assorted blow-off outlet.

Described drum type brake cleaning sieve, electronic air blast winnowing machine and two belts promote conveyer road wheel all are installed, and each equipment can be walked mobile.

When the utility model uses, promote the grain lifting input drum type brake cleaning sieve that conveyer will be mixed with impurity by first belt, at first cleaning is big assorted separately by drum type brake cleaning sieve, in the drum type brake cleaning sieve drum sieve is housed, its screen cloth is a woven wire, and mesh is greater than grain, and drum sieve rotates during work, the grain grain passes the discharging opening that screen cloth enters the drum sieve below, and big mixing from big assorted outlet discharged; Remove excessive assorted grain and promote the feeding hopper that conveyer promotes the electronic air blast winnowing machine of input by second belt again, little assorted by electronic air blast winnowing machine cleaning, start electric blower, open the adjustable plate of feeding hopper, allow grain grain and foreign material slowly fall, in the process that falls, little assorted being blown discharged from blow-off outlet, and grain falls into the mouth of putting out cereal, the grain of clearing up is by mouthful discharge of putting out cereal, warehouse-in.

With prior art now than, advantage of the present utility model is:

(1) cleaning efficiency height reaches 0.5-0.9% through cleaning with rear impurity, meets into library standard the utility model cleaning efficiency fully: big by assorted＞90%; Little assorted＞50%, getting a foothold contains grain less than 1%; And the box-like cleaning efficiency of former two drum type brakes cleaning screen banks: big mixing is 85%, and little mixing is 40%, and it is 3% that leftover bits and pieces contains grain;

(2) energy savings, power consumption is low; The power of the box-like cleaning of former 2 drum type brakes cleaning screen banks is 15KW, and the power of a whole set of unit of the utility model of same disposal ability only is 2.7 kilowatts.

Can change corresponding sieve mesh according to cereal-granules volume size when (three) using, can clean different cereal;

(4) production capacity height, treating capacity is big, and stream time is long;

(5) a whole set of unit low price, the price of the box-like cleaning of former 2 drum type brakes cleaning screen banks is 100,000 yuan, and 1.5 ten thousand yuan of the price deficiencies of a whole set of unit of the utility model of same disposal ability;

(6) price for repairing and running cost are low.
