Description

The invention relates to the sorting of bulk materials, and more specifically to the 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, where it is necessary to separate the mixtures by specific weight.

The purpose of the invention is to increase the productivity and quality of the separation process of difficult-to-separate bulk mixtures by adjusting the number of rows of ripper spikes acting on the mixture depending on the content of the light and heavy fractions.

Figure 1 presents the structural diagram of the proposed machine; Fig. 3 shows the arrangement of the ripper studs at their relative displacements; in FIG. 3 a rotor with rings with studs mounted on it, sectioning in axonometry.

The machine contains a vertical cylindrical non-perforated rotor 4 located in the casing 1 rotating from the pulley 2 and oscillating from the vibrator 3. Adjusting rings 5 with rippers 6 are fixed to the inner surface of the rotor. To secure the rings to the rotor, grooves 7 are provided in which the entrance There are 8 studs. At the top of the machine there is a spreader 9, at the bottom there is a separator 10 with unloading by scrapers: 11 for a light fraction and 12 for a heavy one. To collect the light and heavy fractions, trays 13 and 14 are respectively installed.

Grain cleaning-sorting machine works as follows.

The mixture coming from the spreader 9 onto the inner surface of the rotor 4 of the grain is pressed against it due to its rotation, and due to axial oscillations it moves from top to bottom, interacting with the rippers 6, which also prevent the mixture from rapidly sliding on the rotor heavy and light fraction. At the bottom

The parts of the redistributed machine with the separator 10 are divided into light and heavy fractions, which are sent to the chutes 13 and 14 by scrapers 11 and 12.

Movable rings located on the inner surface of the rotor 4

5, with the rippers 6 fixed on them, enable the latter to be displaced one relative to the other due to the relative rotations of the rings 5 around the axis of the rotor 4. The movements and fastening of the rings S on the rotor 4 are adjusted

by means of adjusting fixing pins 8, which extend outside the rotor 4 and are able to move relative to its surface due to the presence of slots 7 therein.

The installation of all rings 5, for example, in the initial zero position means that all shigal-rippers 6 are located one under the other, i.e. vertical rows. And the range will be as much as the types of rippers

6 has on one ring 5, i.e. the least amount. It is advisable to work with such a position of spiked rippers when separating easily separable mixtures, i.e. mixtures in which the particles have a low roughness and the percentage of the fraction is almost constant.

At. processing of difficult-to-separate mixtures with high roughness of seeds and with large differences in the percentage of the fraction it is necessary to move the rings one relative to the other, and hence the rippers, i.e. increase the number of spikes acting on the mixture being mixed.

So the rippers are rippers,

mounted on movable rings with the possibility of relative movement, allow changing the degree of impact of rippers to establish the most optimal mode

redistribution in each individual; This improves the quality of the separation process and increases the productivity of the machine.
