A kind of separating sieve

Technical field

The present invention relates to technical field of agricultural machinery, specifically a kind of separating sieve.

Background technology

Soybean, generally all refer to its seed, nutritious, various bean product are very popular, the nutritional labeling that the soybean of different cultivars contains is also different, in food processing factory, be not that the soybean of results is all used for doing a kind of food, the operation that when selecting according to the size of the particle of soybean, before processing one is important, the main purpose of this operation is to remove the impurity mixed with soybean, in addition, also will by soybean not of uniform size separately, thus the object reached soybean purification and classification, there is a lot of soybean separator in the market, but its separating effect is poor, inefficiency, and often cause soybean particle broken, so it is simple to be badly in need of a kind of structure, good separation effect, the soybean separating sieve that operating efficiency is high.

Summary of the invention

Technical problem to be solved by this invention be to provide a kind of reasonable in design, lower-cost, operating efficiency is high, the quick sorting of soybean can be realized and the separating sieve of soybean appearance can not be destroyed, i.e. a kind of separating sieve.

Technical problem to be solved by this invention realizes by the following technical solutions:

A kind of separating sieve, comprise sieve nest, top sieve, lower sieve, driving section and conveying device, described sieve nest sidewall is provided with sliding way and glide path, described sieve nest sidewall is provided with deflector, and deflector is positioned at below glide path, bottom described sieve nest, shifting roller is installed, and the quantity of shifting roller is four, described top sieve is arranged in sliding way, described lower sieve is positioned at below top sieve, and lower sieve is arranged in glide path, described driving section is arranged on bottom sieve nest, described conveying device is positioned at lower sieve below, be connected bottom conveying device and sieve nest, and conveying device is connected with driving section.Top sieve and lower sieve are under the drive of driving section, reciprocal quick return is done in sieve nest, relative rolling is there is with the ground of top sieve and lower sieve in top sieve and the soybean in lower sieve under the effect of inertia, thus soybean is screened, after top sieve and twice screening of lower sieve, foreign material and the less soybean of particle drop down onto on conveying device, and conveying device is exported sieve nest.

Be provided with a discharging opening on the right side of described top sieve, the described top sieve left and right sides is all provided with a guide wheel, and the quantity of a guide wheel is six, is provided with a sieve aperture in the middle part of described top sieve, and the quantity of a described sieve aperture is no less than two.

Described lower sieve right side is provided with No. two discharging openings, and the described lower sieve left and right sides is all provided with No. two guide wheels, and the quantity of No. two guide wheels is six, and described lower sieve middle part is provided with No. two sieve apertures, and the quantity of described No. two sieve apertures is no less than two.

Described driving section comprises motor, driven pulley and belt, described motor is arranged on bottom sieve nest, described motor output shaft end is connected with driving pulley by flat key, described motor output shaft end is connected with conveying device again, described belt is arranged between driving pulley and driven pulley, and described driven pulley is fixed with driving crank, and described driving crank one end is hinged with a rocking bar and No. two rocking bars, a described rocking bar and top sieve one end are hinged, and described No. two rocking bars and lower sieve are hinged.

The internal diameter of a described sieve aperture is 3.5 ~ 4.5mm, and the internal diameter of described No. two sieve apertures is 2 ~ 3mm, because the internal diameter of a sieve aperture is larger than the internal diameter of No. two sieve apertures, so can according to the large young pathbreaker soybean classification of the particle of soybean through twice sorting.

The invention has the beneficial effects as follows: the present invention has the lower and operating efficiency advantages of higher of reasonable in design, cost, the quick sorting of soybean can be realized and the appearance of soybean can not be destroyed, easy to operate, use safety.
