Description

Изобретение относится к сельскохозяйственному машиностроению, в частности, к машинам для уборки картофеля и корнеплодов.The invention relates to agricultural machinery, in particular, to machines for harvesting potatoes and root crops.

Недостатком их является уменьшение ’ в процессе работы просветов между роликами из-за налипания почвы на боковые плоскости роликов.Their disadvantage is a decrease ’during the operation of the gaps between the rollers due to soil sticking to the lateral planes of the rollers.

Наиболее близок к изобретению ро- ¹⁵торный сепаратор машин для уборки корнеклубнеплодов, содержащий параллельные и последовательно расположенные вращающиеся в одну сторону валы _мс закрепленными на них лопастными роликами, причем ролики каждого последующего вала установлены между роликами каждого предыдущего вала, а одна из лопастей каждого ролика удлинена [2]. ,The most close to the invention Po- separator ¹⁵ torny machines for harvesting root crops, comprising parallel and sequentially disposed in one side of the rotating shafts of _vehicles with fixed thereon blade rollers wherein the rollers of each successive roller shaft mounted between each previous shaft, and one of the blades of each roller lengthened [2]. ,

Однако в таком сепараторе форма удлиненных лопастей не позволяет эффективно очищать зазоры и соседние валики от налипшей почвы и предохранять их от наматывания ботвы, вследствие чего производительность сепаратора снижается.However, in such a separator, the shape of the elongated blades does not allow to effectively clean gaps and adjacent rollers from adhering soil and to protect them from winding tops, as a result of which the performance of the separator decreases.

С целью повышения эффективности сепарации почвы путем очистки боковых плоскостей роликов от налипшей почвы в предлагаемом роторном сепараторе концы удлиненных лопастей роликов выполнены лопатообразной формы шириной равной расстоянию между боковыми плоскостями роликов.In order to increase the efficiency of soil separation by cleaning the lateral planes of the rollers from adhering soil in the proposed rotary separator, the ends of the elongated roller blades are made in a spade-like shape with a width equal to the distance between the lateral planes of the rollers.

Рабочие поверхности удлиненных лопастей изогнуты по радиусу в сторону, противоположную направлению их вращению, а рабочие поверхности лопастей выполнены эластичными.The working surfaces of the elongated blades are curved along the radius in the direction opposite to the direction of their rotation, and the working surfaces of the blades are made elastic.

На фиг. 1 изображена секция предлагаемого роторного сепаратора машин для уборки корнеплодов, вид сбоку; на фиг. 2 - то же, вид сверху.In FIG. 1 shows a section of the proposed rotary separator of machines for harvesting root crops, side view; in FIG. 2 - the same, top view.

Секция роторного сепаратора содержит несколько параллельных и последовательно расположенных валов 1, на $ которых закреплены ролики 2, например, шестигранной формы; причем ролики каждого последующего вала установлены между роликами каждого предыдущего. Ролики имеют удлиненные ло- to пасти 3. Концы 4 лопастей имеют лопатообразную форму и изогнуты радиально в сторону, противоположную направле нию их вращения.The rotary separator section contains several parallel and sequential shafts 1, on $ of which rollers 2 are fixed, for example, in a hexagonal shape; moreover, the rollers of each subsequent shaft are installed between the rollers of each previous one. The rollers have elongated bones of the mouth 3. The ends of the 4 blades have a spade-shaped shape and are curved radially in the direction opposite to the direction of their rotation.

Роторный сепаратор работает еле- 15 дующим образом.The rotary separator works in the most efficient way.

Корнеклубненосная масса вместе с ботвой поступает на секцию роторного сепаратора и под воздействием вращающихся лопастных роликов интенсивно 20 рыхлится и транспортируется в направлении вращения роликов, при этом мелкая почва просеивается через просветы между роликами.The root-bearing mass together with the tops enters the rotary separator section and, under the influence of the rotating blade rollers, is intensively loosened and transported in the direction of rotation of the rollers, while fine soil is sifted through the gaps between the rollers.

Удлиненные лопасти роликов, прохо- 25 дя между боковыми плоскостями роликов, закрепленных на последующих валах, очищают их от налипшей земли и препятствуют наматыванию растительности на валики.The elongated roller blades, passing between the lateral planes of the rollers, mounted on subsequent shafts, clean them of adhering earth and prevent winding of vegetation on the rollers.

Предложенный роторный сепаратор улучшает просеивание почвы, повышает производительность машин для уборки корнеклубнеплодов и дает возможность применять их для уборки на влажных почвах.The proposed rotary separator improves screening, increases the productivity of machines for harvesting root crops and makes it possible to use them for harvesting on moist soils.

Claims

(5) ROTARY SEPARATOR OF CLEANING MACHINES The invention relates to agricultural machinery, in particular, to machines for harvesting potatoes and root crops. Rotary separators are known, comprising parallel shafts rotating in one direction with the oolics of various configuration 1 mounted on them in a staggered manner with overlap. Their disadvantage is a decrease in the process of work of the gaps between the rollers due to soil sticking to the side surfaces of the rollers. Closest to the invention is a rotary separator for harvesting root and tuber crops containing parallel and sequentially rotating in one direction shafts with paddle rollers attached to them, with the rollers of each subsequent shaft installed between the rollers of each previous shaft, and the CORNE blades of each roller are elongated 2 However, in such a separator, the shape of the elongated blades does not effectively clean the gaps and adjacent rollers from sticking soil and prevent them from winding. haulm, so that the performance of the separator decreases. In order to increase the efficiency of soil separation by cleaning the juice planes of the rollers from sticking soil in the proposed rotary separator, the ends of the elongated blades of the rollers are made with a spade-shaped width equal to the distance between the side planes of the rollers. The working surfaces of the elongated blades are bent radially in the direction opposite to the direction of their rotation, and the working surfaces of the blades are made elastic. FIG. 1 shows a section of the proposed rotor separator of the machines 390 for harvesting root crops, side view; in fig. 2 - the same, top view. The section of the rotor separator contains several parallel and successive shafts 1, on which the rollers 2 are fixed, for example, of hexagonal shape; moreover, the rollers of each subsequent shaft are installed between the rollers of each previous one. The rollers have elongated blades 3. The ends of the L blades have a spatulate shape and are bent radially in the direction opposite to the direction of their rotation. Rotary separator works as follows. The root-stock mass together with the tops is supplied to the section of the rotary separator and under the influence of the rotating blade rollers is intensively loosened and transported in the direction of rotation of the rollers, while the fine soil is sifted through the gaps between the rollers. The elongated blades of the rollers, the passage between the side planes of the rollers fixed on the subsequent shafts, clean them of the stuck earth and prevent the winding of vegetation on the rollers. The proposed rotary separator improves screening of the soil, increases the productivity of machines for harvesting root and tuber crops and makes it possible to use them for harvesting on wet ones. soils. Claim 1. Rotary separator for harvesting root and tuber crops containing parallel and sequentially rotating in one direction shafts with paddle rollers fixed to them, rollers of each subsequent shaft are installed between the rollers of each previous shaft, and one of the vanes of each roller is elongated, differing in that, in order to increase the efficiency of soil separation by cleaning the side planes of the rollers from the adhering soil, the ends of the elongated blades of the rollers are made with a shovel-like shape s width equal to the distance between the side planes of the rollers. 2.
