The invention relates to devices for separating the grain size of grain mixtures or by-products of grain processing, as well as components of animal feeds, and can be used in mill, large, and formula-feeding enterprises, as well as grain storages.

The purpose of the invention is to increase the productivity of the machine by expanding the zone of contact of the material moving from the feeder with the surface of the sieve drum.

On goig. 1 is a schematic diagram of the proposed machine; in fig. 2 is a section A-A in FIG. 1j in FIG. 3 section b-b in FIG. one; in fig. h - section BB in FIG. one.

The vibrating centrifugal screening machine contains a vertical sieve drum 1 rigidly fixed to the shaft 2. A cylindrical or other casing 3 is located coaxially with it, containing the bottom of the h with elastic supports 5. The bottom bearing 7 of the shaft 2 of the grate drum 1 mounted on the bottom of the h, and the top 8 on the cover 9 of the casing 3- The casing 3 contains slopes 10, mounted on a screw line, sieve cleaners 11. On the shaft 2 of the drum 1 there is a conical spreader 12 and a sieve feeder made in the form of the spacing of the sockets 13 and 1h with blades 15 and 1b radially mounted on their upper surface. The blades 15 of the upper outlet 13 are attached to the end rim of the sieve drum 1.

Between the 13 and 1h sockets there is a socket 1 / with blades 1 &. Sockets 13 and 17 are symmetrically located relative to the shaft 2 bore

from (the grain size in the underlying P 1h is less than that of the overlying P 17. The grain with impurities is distributed by the conical spreader evenly around the circumference, falls on L 15 and partially through the apertures of P 13 and 17, respectively, flows on P G / and 1 h. Under the action the centrifugal forces, the mixture is supplied to the inner surface of the RB 1 at different levels in height, which reduces the thickness of the product layer on RB 1..2 cp, f-ly, h il.

ti, and the total area of the hole in the underlying outlet 17 is smaller than in the overlying outlet 13. Outlets 13, 1 / and 1h are mounted on the shaft with the possibility of moving them in height.

The rotation of the sieve drum 1 is carried out from the electric motor by means of a V-belt transmission. Electrovibrators b provide the oscillation of the system: the casing 3 and the sieve drum 1 in the vertical direction. In order to withdraw the product fractions, the blades 19 and 20 and the outlet pipes 21 and 22, respectively, are provided for the aisle and converging fraction.

Sifting machine works as follows.

Grain with impurities (flour with impurities) is fed to a conical spreader 12, which distributes the mixture evenly around the circumference. Then it falls onto the vanes 15 and partially through the holes of the socket 13 to the socket 17. A part of the product from the socket G / enters through its holes to the socket 1h.

Under the action of centrifugal energy, the mixture is supplied to the inner surface of the sieve drum 1 at three levels of the sockets 13, 1h and 17. The feed levels can be changed by repositioning the sockets 1h and 17 on the shaft 2 relative to the sockets 13.

When the sieve drum 1 oscillates in the vertical direction and rotates it, the mixture under the action of centrifugal inertial forces presses against the surface of the sieve and moves downwards. The grain passes through the sieve holes and is removed from the machines through the outlet 21 with the help of slopes 10 and vanes 19. Large impurities move 6-5
