Abstract

The invention is intended to sort agricultural crops and to separate other bulk materials. The purpose of the invention is to improve the quality of separation of multicomponent seed mixtures by eliminating the rolling of elongated seeds across the vibration paths (VD) and ensuring the possibility of separating different mixtures by changing the orientation of the electromagnetic field. The vibroseparator includes an inclined OBD with a friction working surface, a feeder and receivers of separation products. Under the database, the system of isolated paraplel electrodes (E) 2 is installed in the same plane (P) parallel to it. Moreover, 32 are installed at an angle to the longitudinal axis of the VD. This allows the particles to be oriented along the line of the largest slope of the surface, which prevents them from rolling. In parallel, the locations of the main 32 are installed in several P additional E2s. They are parallel to each other in each P and inclined at different angles to the longitudinal axis of the VD. Depending on the particular seed mixture, the voltage is applied to that pair of alternating main and additional 32, the slope of which to the longitudinal axis of the VD is the best. 1 hp f-ly, 2 ill.

 The invention relates to maps for cleaning and sorting belts of agricultural crops, preferably vegetable, bast, medicinal and flower plants, and can also be used to separate other bulk materials.

The aim of the invention is to improve the quality of separation of multicomponent seed mixtures by eliminating the rolling of elongated seeds across the vibration tracks, as well as ensuring that different mixtures can be separated by changing the orientation of the electromagnetic field. ,one

Fig. 1 shows the arrangement of the electrodes; figure 2 is a structural diagram of the separator.

With the ratio of the transverse 3 and the longitudinal ot of the inclination angles pfd 1, the angle h (the angle of inclination of the electrodes) should be equal to 45 °, and at p / о С, i.e. in the absence of lateral tilt, the angle .h must be equal to 90 °. This is explained by the fact that with pM 1, i.e. with equal angles of transverse р and longitudinal ot. the slopes of the largest slope of the surface are located at an angle of 45 ° to the longitudinal axis of the plane, at (3 °, i.e., in the case where the deck is tilted only in the longitudinal direction, the line of the largest slope coincides with the longitudinal axis of the plane or parallel to the latter. In the case of Ы 0;

/ 3 f Oh, i.e. when tilted only, the line of the largest slope is oriented perpendicular to the longitudinal axis. To prevent the elongated particles from rolling, they must be oriented along the line of the largest slope of the surface, and this can be ensured when the alternating polarity electrodes are perpendicular to the line of the largest slope (elongated particles are oriented along the lines of force5, i.e., perpendicular to electrodes).

Vibroseparator includes a working body in the form of one or several non-perforated vibrodeck 1, reinforced from below by a system of intersecting intersecting polarity electrodes 2, parallel to the plane of the vibroject. These electrodes are located under various angles to the longitudinal

axis vibrodeki ,. Vibrodeki are installed on the vibration table 3, to which vibration exciter 4 is attached. The vibration table rests on an elastic suspension in the form of compression springs 5 mounted on the frame 6. To supply the initial mixture, there is a feeder 7, and receivers 8 for collecting the separated fractions. slope in the longitudinal direction at an angle ci and in the transverse direction at an angle p, for adjustment (the mechanisms of which are mechanisms 9 and 10, respectively

Vibroseparator works as follows.

The initial seed mixture from the feeder 7 enters the working friction surface of the vibrodeck 1, which is brought into: an oscillating motion by the exciter 4. Under the influence of vibrational influences on an inclined plane, the mixture separates; elongated, rougher particles are transported along more aligned trajectories, and smoother rounded particles along trajectories of greater curvature. This is because the elongated particles

stronger than round ones are attracted by the electric field and therefore the difference in friction forces acting on the particles increases. Under the influence of vibrations, rougher particles have a greater ability to be transported upwards along an inclined plane than smooth ones.

The voltage is not applied to all electrodes at the same time. Since each pair of alternating main and additional electrodes has its own angle of inclination to the longitudinal axis of the separator, and it depends on the particular seed mixture and is determined by the ratio of the transverse and longitudinal oi of the angle of inclination of the working device, the voltage is applied to that pair of alternating electrbds, the angle which, the outcome of these conditions is the best.

As shown by experimental studies, for most seeds of vegetable, bast, medicinal, and flower crops, the ratio of the transverse (3 and longitudinal angles of inclination of the working body of the separator is such that the line of the largest slope is at an angle of 11 10-30 to the longitudinal axis of the separator).

In this case, the elongated particles of seed mixtures are oriented along the line of the largest slope of the working surface, which prevents them from rolling.
