Изобретение относитс к щеточным очистител м корнеклубнеплодов.BACKGROUND OF THE INVENTION The invention relates to brush sweepers for root and tuber crops.

Известен очиститель корнеклубнеплодов от загр знений, содержащий выполненный в виде упругой спирали барабан с приспособлением дл измерени шага витка спирали l.A well-known cleaner of root crops from soils, containing a drum made in the form of an elastic helix, with a device for measuring the pitch of the helix l.

В этом очистителе при обработке корнеплодов конической формы (свеклы моркови, турнепса и т.д.) в основном очищаютс только верхн и средн их части, а хвостова часть не попадает под действие щеток, в результате чего снижаетс степень очистки.When treating root crops of conical shape (carrot, turnip, etc.), this cleaner mainly cleans only the upper and middle parts, and the tail part is not affected by the brushes, as a result of which the degree of cleaning is reduced.

Известен также очиститель корнеклубнеплодов от загр знений, включающий решетчатый барабан, со стороны выходного отверсти которого жестко закрепленно кольцо, а внутри эксцентрично установлена цилиндрическа щетка 2.Also known is the cleaner of root crops from soils, including a lattice drum, on the side of the outlet of which the ring is rigidly fixed, and a cylindrical brush 2 is installed eccentrically.

С целью повышени качества очистки корнеклубнеплодов от загр знений в предложенном очистителе решетчатый барабан снабжен изогнутыми прутковым пальцами, одни концы которых жестко прикреплены к кольцу по его окружности , а другие отогнуты внутрь барабан и составл ют с его продольной осью острый угол.In order to improve the quality of cleaning of root crops from soil in the proposed cleaner, the trellis drum is equipped with curved rod fingers, some ends of which are rigidly attached to the ring around its circumference, while others are bent inside the drum and form an acute angle with its longitudinal axis.

На фиг.1 изображен предложенный очиститель, общий вид; на фиг.2 разрез А-А на фиг.1.Figure 1 shows the proposed cleaner, a General view; in Fig.2 a section aa in Fig.1.

Очиститель состоит из установленного на раме 1 и заключенного в кожух 2 решетчатого вращающегос барабана 3, со стороны выходного отверсти которого жестко закреплено кольцо 4 с изогнутыми прутковыми пальцами 5, а внутри барабана эксцентрично установлена цилиндрическа щетка 6.The cleaner consists of a lattice rotating drum 3 mounted on a frame 1 and encased in a casing 2, on the side of the outlet of which a ring 4 with bent rod fingers 5 is rigidly fixed, and a cylindrical brush 6 is installed eccentrically inside the drum.

Дл фиксации витков спирали в определенном положении свободно установлена спиральна обрешетка 7, котора расположена на продольных стержн х 8. В зоне загрузки корнеклубнеплодов к опорной раме и диску каркаса жестко прикреплен бункер 9.In order to fix the turns of the spiral in a certain position, the spiral sheathing 7 is freely mounted, which is located on the longitudinal rods 8. In the loading zone of the root and tuber crops, the bunker 9 is rigidly attached to the support frame and the frame disk.

Очиститель работает следующим образом .The cleaner works as follows.

Claims

Roots from the hopper 9 enter the inner cavity of the drum and are affected by the rotating brush 6. As a result of the action of the brush tool mounted eccentrically and the counter-rotating drum, they receive a rotational movement, and the elongated roots and tubers are oriented along the length of the drum. The roots and tubers, placed in the eccentric gap between the brush 6 and the spiral crate 7, are moved to the side to unload in the cleaner casing 2 under the action of the helical winding of the helix and in the result of the tilt of the screen. From the zone through the bunker 9, the root crops fall under the influence of fingers 5, which, as a result of the oncoming movement in the direction of rotation of the brush 6, pull the product into the zone where the gap between the brush and the screen is minimal, this results in more intensive cleaning of root crops from soil, better cleaning the mode of operation of the cleaner is also improved due to the provision of conditions for unloading the product from the screen. Claims of the root crop cleaner for dirt, including a lattice drum, on the side of the outlet of which the ring is rigidly fixed, and a cylindrical brush is installed inside the eccentric, characterized in that, in order to improve the quality of cleaning of root and straw berries, it is provided with curved bar fingers rigidly attached to the ring around its circumference, while others are bent inward of the drum and form an acute angle with its longitudinal axis.
