Изобретение относитс к сельскохоз йственному производству, в част ности к области сепарации зерновых материалов и может быть использовано в пневмосепараторах дл очистки сем н сельскохоз йственных культур от сорных примесей.The invention relates to agricultural production, in particular to the field of separation of grain materials and can be used in pneumatic separators for cleaning seeds of agricultural crops from weed impurities.

Известны пневмрсепараторы, содержащие колеблющуюс воздухопроницаемую деку, на которой происходит разделение материала til .Pneumatic separators are known, containing an oscillating air-permeable deck, where material separation til occurs.

Однако использование таких устройств не позвол ет повышать эффект очистки и удельную зерновую нагрузку .However, the use of such devices does not allow to increase the cleaning effect and the specific grain load.

Известен также пневмосепаратор, включающий воздушную камеру, iвиброплощадку , пористую плиту с регулирующим приспособлением и патрубки дл загрузки исходного материала и разгрузки продуктов разделени t2 .A pneumatic separator is also known, including an air chamber, an i-site, a porous plate with a regulating device and nozzles for loading the source material and discharging separation products t2.

Недостатком известного сепаратора вл етс неравномерное распределение воздушного потока ввиду того, чтоA disadvantage of the known separator is the uneven distribution of the air flow due to the fact that

воздух а воздушную камеру подаетс через боковое отверстие. Это не позвол ет стабилизировать эффект очистки.air and the air chamber are supplied through a side opening. This does not stabilize the cleaning effect.

Цель изобретени - повышение прои.зводительмости сепаратора.The purpose of the invention is to increase the separator production.

Эта цель достигаетс тем, что воздушна камера установлена над пористой плитойj регулирующее приспособление выполнено в виде й1тырей, This goal is achieved by the fact that the air chamber is installed above the porous plate; the regulating device is made in the form of

10 установленных с возможностью изменени формы и высоты, а также обечайка (установлена с возможностью регулировани ее высоты.10 installed with the possibility of changing the shape and height, as well as the shell (installed with the ability to adjust its height.

На чертеже схематично изображе15 но предложенное устройство.In the drawing a schematic view of an image 15 but the proposed device.

Воздушный сепаратор имеет основание 1, виброплиту 2 и закрепленную на ней пористую плиту 3, через которую проход т штыри ;А. Пориста The air separator has a base 1, a vibrating plate 2 and a porous plate 3 fixed on it, through which the pins pass; A. Porous

Claims

20, the plate can be moved and fixed in the vertical direction. A shell 5 is fixed on the porous plate, which can adjust the height of the plate. On the side there is an outlet device 6 with knives 7 for separating the granular mixture, separating it and bringing it out. Air sweat comes from chamber 8, which can have a different shape and is adjustable both in height and in the direction of air supply to the stove. The pneumatic separator works as follows. The grain from the hopper enters the porous plate 3, which oscillates at a certain frequency and amplitude. The air flow, the output from the air chamber 8, runs onto the porous plate and spreads along. her. This forms a thin air film with increased pressure. The grain material on such a non-oscillating surface stratifies. By varying the height of the pins, the resistance to the air flow is changed, and thereby the air pressure is changed. The shape of the pins is changed by replacing the round pins with an elliptical. Then, when the pins are spared on the vertical axis, their resistance to the air film changes, which is formed when the air flow reflects from the plate and falls on the pins. This increases the flow rate, which makes it possible to increase the height of the bed of the loose mixture. Changing the position of the shell, and thereby adjusting the flow of air from the stove, you can increase or decrease the grain layer on the stove. Along with this, the degree of delamination of the grain material varies. When the grain material moves along the vibroplate and as it separates, the layers are cut by the knives 7 and withdrawn through the discharge device 6. The use of the proposed air separator to clean the grain reduces the metal consumption and increases the productivity by 1.5 times compared to the known pneumatic separators. Claim 1. Air separator, which includes an air chamber, a porous plate with a regulating device, a vibrating plate, a shell, loading and unloading devices,. . characterized in that, in order to increase the separator performance, the air discharge chamber is installed above the porous plate, 2. Separator according to claim 1, 1, which is made in the form of rods installed in the With the possibility of changing the height and shape. 3. Separator according to claim t, which is based on the fact that the shell is installed with the possibility of adjusting its height.
