Description
Technical field：
The present invention relates to a kind of grain selection knot screen, belong to mechanical equipment technical field.
Background technology：
Cereal is inevitably mixed into dust, broken rod stamen, leaf, chaff shell, flat grain, bad seed, stone etc. during harvesting
The various impurity mixed in grain, existing cereal removal of impurities typically use winnowing machine, and blower fan crosses wind dedusting, by whirlpool wind
Gather goes out the lighter impurity and dust contained in grain, and is discharged first by suction channel, is produced when mitigating grain screening
Excessive dust pollution, selection by winnowing can effectively remove the lighter impurity and dust that cereal contains, but for big of stone etc.
The impurity of grain can not effectively be removed by selection by winnowing.
In order to solve the above problems, Chinese patent CN201521133713.1 discloses a kind of cereal knot screen, and has
Body discloses following technical characteristic, the device include filtering cabin, feeding chamber, conveyer belt, shield, material retaining hood, actuating unit,
Support bar；Support bar is fixedly installed on filtering cabin bottom, is characterised by that filtering cabin is fixedly mounted on shield, it is integrally located at defeated
Send the bottom of band；Feeding chamber is fixedly mounted on shield, and it is integrally located at the top of conveyer belt；Motor is provided with feeding chamber；
Shield is fixedly mounted at left and right sides of conveyer belt；Material retaining hood is fixedly mounted on conveyer belt side, and it is located at feeding chamber rear end.The dress
Put and mainly cleaned by way of filtering, and device structure it is complicated, it is necessary to setting height(from bottom) it is higher, the capital construction requirement to factory building
Compare high, practicality is not strong.
The content of the invention：
The purpose of the present invention is to provide a kind of grain selection knot screen for above-mentioned problem, and device structure is simple
And the various impurity such as the dust for being mixed into cereal, broken rod stamen, leaf, chaff shell, flat grain, bad seed, stone can be removed effectively.
Above-mentioned purpose is realized by following technical scheme：
Grain selection knot screen, including hopper, the side on described hopper top are provided with blanking funnel, described material
The side of case is provided with blower fan close to the position of described blanking funnel, and described hopper bottom is set below described blower fan
Vibratory sieve is equipped with, net cereal outlet is provided with below described vibratory sieve, described hopper bottom is away from described blower fan
Side be provided with impurity collection bucket, described hopper top is provided with exhaust outlet, be provided with described exhaust outlet dedusting dress
Put.
Described grain selection knot screen, one group of dividing plate slot is provided with inside described hopper, described in one of them
Dividing plate slot inside be provided with dividing plate.
The air outlet of described blower fan and described blanking funnel are arranged to strip, and its length is consistent and described
