Abstract

The solution relates to a sorting device for agricultural products, especially onions, berries and fruits. It can sort material of various sizes and shapes. The sorting device consists of a frame in which sorting ellipsoids are rotatably mounted, between which sorting gaps are created. The sorting ellipsoids are rotated by 90° relative to each other. Their directions of rotation are identical, including peripheral speeds. The sorting ellipsoids can be grouped into sorting fields, where the spacing between the sorting ellipsoids is the same, but different in each field, or they can form a continuous sorting area in which the spacing between the sorting ellipsoids gradually increases.

Description

The invention relates to a sorting device for agricultural products, in particular onions, berries and fruits.

In the known sorting machines, material sorting is most often ensured by a set of conveying elements such as belts, chains, ropes, etc., whose mutual distances gradually increase continuously · For maximum assurance of sorting effect, the driving speed of some elements is different when the diameters of the individual cylinders are graduated, their axes of rotation are always parallel and inclined at a certain angle to the horizontal plane ·

Sorting of material on machines constructed on the principle of gradually increasing gaps between the driving elements has drawbacks · Using different driving speeds of individual elements, damaging brittle material, its undesirable orientation when passing through the machine and last but not least due to inappropriate orientation for mixing of individual fractions · machines with cylindrical sorting elements, due to the rotation of these rollers, the sorted material is drawn in, crushed or deformed, as well as microscopic damage to the surface layer · All known ee screeners are characterized by high energy consumption and high demands on the areas where these machines are installed.

The aforementioned drawbacks are eliminated by a sorting device according to the invention consisting of a frame in which a system of sorting ellipsoids is arranged. The sorting ellipsoids are rotatably mounted in the frame and their directions of rotation are identical to each other, including the peripheral speeds.

256 468 separating fields where the spacing between sorting ellipsoids is the same, but different in each sorting field · Longer the sorting ellipsoids can form a continuous sorting area in which the spacing between sorting ellipsoids gradually increases · However, in both cases the sorting ellipsoids are so that the main ellipsoid axes make a 90 ° angle to each other · The sorting ellipsoids are rotated to each other · So when the sorting ellipsoids rotate, the sorting gaps remain constant between them, only the position of the sorting gaps relative to the ellipsoid axis changes. ellipsoids are attached rubber diaphragm ·

The sorting material ee moves along the sorting ellipsoids perpendicular to their oey rotation, while the elliptical shape of the sorting elements increases their transport effect · The speed of moving the sorting material along the sorting surface can be influenced by changing the inclination of the sorting area or sorting field ellipsoids and through the sorting gaps between them and depending on the size of the sorted material, it gradually falls through the sorting gaps. · The sifted gaps and thus the sorted material is further transported to the appropriate size class containers. The surfaces of the sorting ellipsoids are rubberized or covered with a plastic layer. · Above the sorting ellipsoids, a rubber screen prevents rotation of the sorting material as it moves along the sorting surface. or sorting field and directs its linear movement ·

The design principle of the sorting device according to the invention consists in that sorting ellipsoids are rotatably mounted in the frame, between which sorting gaps are formed and the sorting ellipsoids are rotated relative to each other.

The sorting system according to the invention can be used for sorting berries and fruits in addition to onion, ie material not only of different dimensions but also shapes · The sorting system is characterized by its versatility · The sorting unit equipped with this sorting system is very efficient and low energy consumption in small dimensions · · * 3 * ·

The sorting device according to the invention consists of a frame JL attached to the machine frame 2. In the frame JL, sorting ellipsoids 4 are arranged at intervals x ^ ··· χ _ρ by means of bearings 3, thereby forming sorting gaps 5. The bevel gears 7 of the gear 8 are mounted on the axes 6 of the sorting ellipsoids 4. Above the sorting ellipsoids 4, a rubber screen 9 is attached to the machine frame 2.

The sorting device according to the invention operates as follows. Sorting ellipsoids 4 are rotated by the bevel gears 7 through the bevel gears 7. The sorting material rolling over the sorting ellipsoids 4 gradually sinks, depending on its size, through the respective sorting gaps 5 into the containers in the figures not shown.
