Abstract

The invention relates to animal feed production. The purpose of the invention is to simplify the design, reduce energy and metal consumption. In the concentrated feed production line, a screw conveyor is arranged above the bottom of the combined hoppers for various feed components, which is made with a diameter in each subsequent hopper larger than in the previous one. 2 ill.

The invention relates to agriculture, in particular to equipment for the preparation of animal feed and can be widely used in the construction and food industries.

The aim of the invention is to simplify the design by combining the functions of the conveyor-doeator-mixer by the screw conveyor, reducing energy and metal consumption.

In FIG. 1 is a side view of a flow chart of a concentrated feed preparation line; figure 2 is a longitudinal section of the combined bins.

The concentrated feed preparation line comprises combined hoppers 1 with loading hatches and dispensers (not shown) for various components. At the base of the hoppers 1, a feed screw conveyor batcher-mixer 2 is installed, which passes above the feed hopper of the feed crusher 3. Under the discharge hatch of the feed crusher 3, a feed conveyor 4 is installed, transporting the finished concentrated feed (material) to the feeders.

At the base of the combined hoppers 1, a sectional 5-7 screw 2 is installed, each subsequent 6.7 section of which has a diameter larger than the diameter of the previous section 5.6.

The holes 8 for passage of the screws are in the form of a cylindrical surface.

The line works as follows.

In the bunker A.B.V., (see Fig. 2), pre-determined feed components (material with appropriate additives) are loaded. From the first hopper A section

screw screw 5 with a diameter of di, transports a certain amount of feed component (material) into the second hopper B. In the second hopper B, the screw auger section 6 is due to the fact that its diameter d2 is larger than di, in addition to the feed (material) components coming from hopper A, it captures some more feed components (material) coming into the hopper B from above and mixing them on throughout the hopper B feeds them into the hopper B. In the hopper B section of the screw 7 due to the increase in the diameter da, in comparison with the diameter da, in turn captures a certain amount of feed component, and mixing all three components throughout the length of the hopper B gives ready mixture in proportions depending on the difference between the diameters of the sections of the screw, etc.

In order to prevent swelling of the mixed materials at the places where the screw exits from the hoppers, these exits have the shape of a cylindrical surface 8, covering the exit screw.

The resulting mixture of grain components (material) falls into feed mill 3, where it is ground. Then the finished concentrated feed (mother /

a) by means of an unloading conveyor 4 is transported directly to the place of consumption. .

The proposed design of combined hoppers with a feeding screw screw conveyor-doser-mixer located inside them allows, by changing the diameters of the screws empirically or by calculation, to obtain a mixture with a different composition of the starting materials. This eliminates the need for a dispenser-mixer under each hopper.

Formulas and inventions A concentrated feed preparation line comprising combined hoppers with loading hatches for various components, a screw conveyor, a feed chopper and an unloading conveyor, in order to simplify the construction by combining screw conveyor functions conveyor-dispenser-mixer. To reduce energy and metal consumption, the screw conveyor is located inside the combined hoppers above their bottom and is made with a screw diameter in each subsequent hopper larger than in the previous one.
