SU1282917A1 - Grain cleaning and sorting machine - Google Patents

Abstract

This invention relates to the field of sorting solid materials by specific gravity. The purpose of the invention is to improve the quality of the process of redistribution of difficult-to-separate mixtures by creating spatial oscillations of the rippers in the mixture layer. For this purpose, the rippers are made in the form of rings 6, freely mounted on the inner surface (VP) of a cylindrical non-perforated rotor 4 by means of brackets. Each of the clips is installed with the ability to move in the slots made on the VP of the rotor 4. Grain mixture (L of the CX) tsD;

from the spreader 8, installed in the upper part of the rotor 4, goes to the VP of the rotor 4. Under the action of centrifugal forces, gravity and oscillatory movements of the rotor 4 along its vertical axis, the mixture moves down to the separator 9. Under the action of inertia forces from the rotor oscillations 17

4 rings 6 also begin to swing from top to bottom. As a result of the oscillations of the rings 6, the intensity of their effect on the layer of the mixture, and consequently, the intensity of movement of the particles inside the layer, increases. This is a way for CTBveT to more quickly redistribute particles. 1 hp f-ly, 3 ill.

The invention relates to the sorting of solid materials, for example, seeds of agricultural crops, namely, grain cleaning and sorting machines, and can be used in agriculture in the mill and large industry, as well as in other branches of the national economy. Properties where it is necessary to separate the mixtures by specific weight.

The aim of the invention is to improve the quality of the process of redistributing difficult-to-separate mixtures by creating a spatial channel of the research institute of rippers in the mixture layer.

Fig. 1 schematically shows a grain cleaning-sorting tire, section; in fig. 2 - ring ripper; in fig. 3 - position of the ripper ring at different angles ot of its position relative to the direction of oscillation of the rotor.

The machine contains a casing 1 rotating from the pulley 2 and oscillating from the vibrator 3, a vertical cylindrical rotor 4 with brackets 5 placed on its inner surface and freely mounted with ripper rings 6, a vertical shaft 7. In the upper part of the rotor 4 there is a spreader 8 , and in the bottom - a separator 9 with discharge scrapers 10 and 11, respectively, for a light and heavy fraction, as well as corresponding trays 12 and 13. On the inner surface of the rotor there are grooves 14, in which one of the legs of the brackets 5 is installed.

The grain mixture from the spreader 8 enters the inner surface of the rotor 4. Under the action of centrifugal forces, gravity and oscillatory movements of the rotor 4, the mixture moves down to the separator 9. Under the action of inertial forces from the vertical oscillations of the rotor 4, the rings also start to swing downwards. the location of the ring-rippers 6 on the inner surface of the rotor 4, i.e. when the angle csf between the plane of the ring 6 and the direction of oscillation of the rotor 4 is not equal to zero or 90, the ring 6 makes spatial variations like the figure eight. When d 0, ring 6 performs vertical swings, which are partial spatial. When o (90 the ring 6 will also perform vertical swings, only now its plane will be horizontal when passing the neutral position. By changing the angle o (. The location of the ring 6 on the inner surface of the rotor 4 due to the rotation of one of the legs of the bracket 5 in the grooves 14, On the rotor 4, the magnitude and direction of the amplitudes of the spatial oscillations can be controlled. As a result of the oscillations of the ripper rings 6, the intensity of their effect on the layer increases, and consequently, the intensity of movement of the particles inside three layers, which contributes to their more rapid redistribution.
