Abstract

The invention relates to agriculture, in particular to feed production. The feed preparation line contains two parallel mounted hoppers 4 and 12. The batcher feeders 13 and 14 are adjacent to both ends of the hopper 12. The hopper 12 is divided by a partition 19 into two compartments. Under the hoppers is a rotor 16. 4 ill.

The invention relates to agriculture, in particular to feed production lines.

The purpose of the invention is to improve the quality of feed and the expansion of technological capabilities.

Figure 1 is a top view of a feed preparation line; figure 2 is a section aa in figure 1; in Fig.Z-section bB in Fig.2; figure 4 - node I in figure 2.

In the feed preparation line, a roughage feeder-feeder 1 is installed, consisting of a hydroficated tipping tray 2 and an inclined metering conveyor 3. A hopper 4 with a horizontal axis of rotation adjacent to the conveyor 3 is made of two cylinders 5 connected by blades b and mounted at a distance from each other with the possibility of rotation on the rollers 7, from the opposite side to the load, the hopper is equipped with a capacity in the form of a truncated cone 8, a large base adjacent to the hopper. The cylindrical part of the hopper is enclosed by a casing 9, which covers the free space between the cylinders and has a feed window 10 with a grill of anti-cutting elements 11. The grill is mounted on the inner surface of the casing 9 with the possibility of moving inside the hopper 4 and serves to limit the amount of feed captured by hammers .

The movement of the grate relative to the casing 9 is carried out, for example, by means of a screw-nut pair.

Next to the hopper 4, an additional hopper 12 without a conical tank is installed. To both ends of the hopper 12 are adjacent feeder-dispensers 13 and 14, respectively, of root crops and silage. Between the bunkers under the feed windows 10 and 15, a hammer rotor 16 is installed with the possibility of hammers 17 passing between the opposing elements 11 and 18 and flying them inside the bins 4 and 12 to capture the processed feed. In order to prevent silage and root crops from mixing with each other in the hopper 12, there is a partition (wall) 19 between the cylinders, which is installed in the plane of rotation of the hopper, which divides the hopper into two independent compartments. The supply windows 10 and 15 are interconnected by a curved casing 20 mounted concentrically to the rotor 16 and closing it from above. To discharge the finished product, the line is equipped with an unloading conveyor 21. The rotation speed of each hopper is changed by installing, for example, a variator on the drive mechanism. Working bodies of all

line machines are driven by known technical means.

Lini works as follows.

Coarse feed (hay, straw) in bulk, delivered in bales or rolls is delivered by the vehicle and is unloaded into the tray 2 of the metering feeder 1. When the tray 2 is put into an inclined position by means of a hydraulic jack, the straw goes to the conveyor 3, which is fed into the rotating hopper 4. Similarly, the feeder-dispenser 13 loads into one of the compartments of the hopper 12 the root crops that have been previously cleaned of dirt, and the feeder-dispenser 14 also into the hopper 1.2, but from the other end and into the other compartment, feeds silage or hay. When the bins rotate towards each other, the components located in them move to the supply windows 10 and 15 with the help of the blades 6 and fall under the influence of the hammers 17 of the rotor 16. When the rotor rotates in the direction indicated by the arrow, the hammers 17 fly out through the feed window 10 inwards

bunker 4, grab a portion of straw and move it inside the casing 20 into the bunker 12 through the feed window 15. Since the bunker 12 is divided into two compartments, part of the straw is hammered into the β-silo.

intensively mixed with it and thrown onto the unloading conveyor 21. Another group of hammers introduces the straw into the mass of root crops moving in the second compartment of the hopper cavity 12. The roots from the impact of hammers are crushed, mixed with straw and also thrown onto the conveyor 21. Both feed streams are additionally mixed on the way to the conveyor. Dosage

components is carried out by changing the rotation speed of the respective hopper, which determines the amount of feed. More accurate dosing is carried out by moving the corresponding

grilles of opposing elements inside the hopper relative to its casing. This changes the length of activity of part of the hammers and, accordingly, the amount of material to be captured. In addition, the amount of material captured by the hammers over a wide range can be adjusted using other known technical means, for example, by closing or opening the corresponding part of the supply window. By conveyor 21, the feed mixture is ready to be loaded into the feed distributor. The use of this production line allows strictly metered feeding of the three main components for mixing due to the fact that each

the component is fed independently, while all feed materials do not require preliminary grinding. In addition, the chopper in the line interacts with the feed hoppers directly, without intermediate devices. At the same time, the quality of the invention is improved. A feed preparation line comprising a feed hopper with a horizontal axis of rotation adjacent to one of the ends of each hopper, a metering feeder and a rotor located under the hopper, under which a collection conveyor is arranged, characterized in that, for the purpose of

of the produced mixture, the line design is simplified and the technological reliability of the working process is improved due to the elimination of intermediate links between the feeding and grinding working bodies during the processing of feed directly in the initial state.

To improve feed quality and expand technological capabilities, it is equipped with an additional feed hopper and two metering feeders adjacent to the ends of the additional feed hopper and dividing the latter into two compartments, with a partition installed in the plane of rotation of the hopper.
