Background

Cereal crops are also known as "cereal crops". Belonging to the family Poaceae, except buckwheat of the family Polygonaceae. It is a crop which uses seeds to provide food for people and feed for livestock. The grain crops mainly comprise rice, wheat, barley, rye, oat, corn, sorghum, millet and the like. The grains are called 'grains' as food, the grains are called 'grains' as shell or palea, the rice is called 'rice' as shell, and the rice is one of staple food for people. The granules contain a large amount of starch and a certain proportion of protein and fat. Besides providing concentrated feed, the grain crops can be harvested as green feed or silage before the grains are mature. The straws and the sugar bran can be mostly used as feed.

The working principle of the invention is as follows: when the light impurity treatment of cereal crops is carried out, firstly, the cereal crops are poured from the feeding port 3c, then the first cover plate 3a is inserted at the top of the screening box 1, so that the cereal crops are thrown to the outside of the screening box 1 when the filtering plate 3b shakes, the design of the lifting groove can be grasped by hands, the material separating plate 3c1 provides a separating effect, and the filtering plate 3b is divided into two parts by the partition plate 3c2, so that the light impurity treatment of two different types of cereal crops can be conveniently carried out simultaneously, when the light impurity treatment of the cereal crops is carried out, the observation window 4a1 can be observed by people, so that the treatment condition can be timely checked, the treatment process is transparent, and the light impurity treatment efficiency of the cereal crops is improved.

When processing heavier impurities in cereal crops such as sand, stone and the like, firstly, the driving motor 3d is started through the controller 2, so that the driving motor 3d drives the rotating shaft 3f1 fixedly connected with the output end thereof to rotate, thereby driving the two cams 3f3 to rotate, when the two cams 3f3 rotate to be collided with the two ejector rods 3f4, the two ejector rods 3f4 are pushed upwards, and further the top plate 3f2 is pushed upwards, because one end of the filter plate 3b close to the contact pin 4c is hinged with the screening box 1, one end of the filter plate 3b far away from the contact pin 4c is shaken upwards, thereby the cereal crops are sprinkled at a certain height, because each filter hole is smaller than the cereal crops, the heavier impurities in the cereal crops such as sand, stone and the like are discharged from the filter holes, the top of the filter holes with the wedge-shaped structure is designed to be convenient for the heavier impurities to fall, when the ejector rods 3f4 are pushed, the reset spring 3f8 plays a reset role, and the jacking is completed each time, so that the ejector rod 3f4 automatically descends and rises back to wait for jacking next time, and simultaneously plays a buffering role to prevent the filter plate 3b from being jacked up to be damaged when the jacking force of the ejector rod 3f4 is too large.

When the rotating shaft 3f1 on the output end of the driving motor 3d rotates, one top plate 3f2 is forced to push up, the driving wheel 3f6 rotates, so as to drive the other driving wheel 3f6 and a plurality of driven wheels 3e4 to rotate through the belt 3e5, and further drive the other top plate 3f2 to push up, so that the filter plate 3b shakes to discharge heavier impurities, the pushing up forces of the two top plates 3f2 are matched, the cereal crop conveying function to the lower end of the screening box 1 can be achieved, simultaneously, when the plurality of driven wheels 3e4 are forced to rotate, the plurality of fans 3e3 rotate, so as to generate negative pressure, light impurities in the cereal crops are sucked out through a plurality of air inlets, the design of the air outlet is convenient for the light impurities in the cereal crops such as roots, stems and leaves or mildewed and shrunken cereal crops to enter and thus to be discharged into the protective shell 3e1, so as to provide a discharge channel for the, the first collecting plate 3e6 is used to collect the lighter impurities while the first collecting plate 3e6 can be withdrawn to facilitate the timed or periodic disposal of the lighter impurities. When heavy impurities such as sand and stone in the cereal crops fall to the lower part of the filter plate 3b from the plurality of filter holes, the heavy impurities automatically fall onto the second collecting plate 1a and then slide out from the feeding slide way 1b, so that the heavy impurities are regularly or periodically treated, and the accommodating space is provided for the accommodating groove. Because the adsorption component 3e applies the negative pressure principle, and the negative pressure principle is established, the whole circulation of air must be ensured, namely, the air is ensured to enter and be discharged without being blocked, and therefore, an air outlet is designed to allow the entered air to circulate out.

After impurity in the cereal is got rid of, start the output downwardly extending of two electric putter 4b3 through controller 2, thereby make two scraper blades 4b2 downwardly extending, until the bottom of every scraper blade 4b2 all with the top laminating of screening case 1, then first slip table 4b1 drives two electric putter 4b3 and stretches out to the one end of keeping away from filter 3b, and then discharge cereal screening case 1, contact pin 4c is used for inserting two sacks, because the discharge port is also divided into two by baffle 3c2, and then make two kinds of cereal of discharged effectively separate, further conveniently collect to two sacks.

It should be understood that the above-described embodiments are merely preferred embodiments of the invention and the technical principles applied thereto. It will be understood by those skilled in the art that various modifications, equivalents, changes, and the like can be made to the present invention. However, such variations are within the scope of the invention as long as they do not depart from the spirit of the invention.
