Цель изобретени - повышение раз- дел ющей способности устройства.The purpose of the invention is to increase the separation capacity of the device.

На фиг. 1 представлена схема устройства , вид сбоку; на фиг. 2 - схема взаимодействи участков горки.FIG. 1 shows a diagram of the device, side view; in fig. 2 - diagram of the interaction of sections of the hill.

Устройство содержит транспортирующуюThe device contains a transport

растительных примесей с пальчатой поверхностью контура 2 при переходе их с контура 3 способствует то, что при огибании ленты контура 2 нижнего вала пальцы 4 расход тс по радиусу, а затем на плоском участке между валами пальцы 4 сближаютс . При облегании ленты верхнего вала контура 2 пальцы 4 вновь расход тс , что способствует более быстрому сходу растительных примесей с контура 2.vegetable impurities with a finger-like surface of the contour 2 when they are transferred from the contour 3 contributes to the fact that when the ribbon of the contour 2 of the lower shaft envelops the fingers 4 diverge radially and then in a flat area between the shafts the fingers 4 approach each other. When the ribbon of the upper shaft of the contour 2 is tightened, the fingers 4 are re-consumed, which contributes to a more rapid descent of vegetable impurities from the contour 2.

горку 1 с движущейс вверх пальчатой 10 Пальцы 4 также выталкивают из раститель- поверхностью, имеющей верхний 2 и нижнийных примесей застр вшие в них корнеклубнеплоды , которые вновь скатываютс по контуру 3 вниз. На сходный конец 6 участка 3 поступает ворох со значительно меньшим содержанием растительных и почвенных примесей, поэтому верхние участки корнеклубнеплодов всегда выступают над примес ми, тем более-это имеет место потому, что обычно минимальный размер корнеклубнеплода больше, чем раз- сто нии меньшем суммы длин пальцев 4 20 мер примесей, лежащих на пальчатой по- и 5. Пальцы 4 и 5 выполнены, напри-верхности. В св зи с этим щетка 7, возмер из резины, и жесткость пальцев 4 вы-действу только на корнеклубнеплоды, снимает их со сходного конца 6 горки 1, ускор процесс разделени обрабатываемого потока на составные компоненты.slide 1 with an upward-moving palmate 10 Fingers 4 are also pushed out of a plant with a surface having upper 2 and lower impurities, the roots and roots stuck in them, which again roll down along contour 3 downwards. A heap with a much lower content of plant and soil impurities arrives at the similar end 6 of section 3, therefore the upper sections of the root crops always protrude over the impurities, all the more so because usually the minimum size of the root crops is larger than the sum of the smaller fingers 4 20 measures of impurities lying on the finger-like and 5. Fingers 4 and 5 are made, on the surface. In connection with this, the brush 7, made of rubber, and the stiffness of the fingers 4, acting only on the roots and tubers, removes them from the similar end 6 of the slide 1, has accelerated the process of dividing the treated stream into its constituent components.

Направление движени пальчатой поверхности противоположно направлению движени ворса щетки 7, поэтому корнеклубнеплоды , проход под щеткой 7 и взаимодейству с пальцами 5 и ворсом щет3 участки, расположенные под разным углом к горизонту (он, «2). Верхний 2 и нижний 3 участки горки 1 выполнены из отдельных транспортерных контуров, причем 15 рабоча поверхность верхнего участка 2 расположена под большим углом к горизонту , чем рабоча поверхность нижнего участка 3, т. е. . В местах прилегани контуров основани их расположены на располнена большей, чем жесткость пальцев 5. Привод транспортерных контуров 2 и 3 (не показан) выполнен обеспечивающим верхним участкам большую скорость, чем нижним . Над сходным концом 6 нижнего участка 3 горки 1 установлена встречно вращающа с щетка 7. Устройство оснащено транспортерами 8-10 соответственно дл загрузки и выведени корнеклубнеплодов Зо и примесей и снабжено шторками 11.The direction of movement of the finger surface is opposite to the direction of movement of the pile 7 of the brush, therefore the roots and tubers, the passage under the brush 7, and interact with the fingers 5 and the pile of the brush 3 areas located at different angles to the horizon (he, 2). The upper 2 and lower 3 sections of the slide 1 are made of separate conveyor contours, with 15 the working surface of the upper section 2 is located at a greater angle to the horizon than the working surface of the lower section 3, i.e. In the places where the contours of the base lie, they are located on a wider than the stiffness of the fingers 5. The conveyor contours 2 and 3 (not shown) are driven to provide the upper sections with greater speed than the lower ones. Over the similar end 6 of the lower section 3 of the slide 1, a counter-rotating brush 7 is installed. The device is equipped with conveyors 8-10, respectively, for loading and removing Z20 root crops and impurities and equipped with shutters 11.

Устройство работает следующим образом .The device works as follows.

ки 7, дополнительно очищаютс от налипших примесей, которые вынос тс контуром 3 на транспортер 10.ki 7, are additionally cleaned of adhering impurities that are carried by loop 3 to conveyor 10.

Claims

1. A device for separating root and nourishment crops from impurities, containing a conveying slide with a finger-like surface, having upper and lower portions located at different angles to the horizon, characterized in that, for the purpose of the conveyor, so that the separating ability does not fall; - whether on the conveyor 9. In the upper section and the lower sections of the slide are made of

ke 2 part of the impurities is allocated to the conveyor 10, and the root crops and the remaining impurities enter the lower section 3, where the components of the mixture are rolled to different lengths: impurities to a smaller length and return to the upper section 2, the roots and tubers roll out to a greater length and a greater part slides off the slide 1 from the similar end 6. The roots and tubers remaining in section 3 arrive at section 2. Soil impurities that have fallen between fingers 5 descend from circuit 3 through the gap to the conveyor K). Vegetative impurities are combed out by more rigid pal45

2. The device according to claim 1, characterized in that the stiffness of the fingers of the upper portion 50 is made greater than the stiffness of the fingers of the lower portion of the slide, and the drive of the conveyor contours is made providing the upper portion with greater speed than the lower ones.

3. The device according to claim 1, characterized by

4 contour 2 from the fingers 5 contour 55 in that the counter rotating brush is mounted over the similar end of the lower par 3 and directed through the upper shaft part of the hill.

vegetable impurities with a finger-like surface of the contour 2 when they are transferred from the contour 3 contributes to the fact that when the ribbon of the contour 2 of the lower shaft envelops the fingers 4 diverge radially and then in a flat area between the shafts the fingers 4 approach each other. When the ribbon of the upper shaft of the contour 2 is tightened, the fingers 4 are re-consumed, which contributes to a more rapid descent of vegetable impurities from the contour 2.

ki 7, are additionally cleaned of adhering impurities that are carried by loop 3 to conveyor 10.
