Description

The utility model relates to agriculture and can be used in animal husbandry for the preparation and distribution of stalk feeds and for laying litter during their grinding, for example straw, regardless of their harvesting technology: bales, rolls, in bulk.

Known chopper-distributor of feed [1], containing a hopper mounted on the frame, feeding conveyor in its bottom, loading and unloading device, feed feed mechanism, grinding rotor with a vertical axis of rotation. The disadvantage of this grinder-distributor is the low reliability of the working process due to insufficient tedding of the material, clogging of the material of the feed conveyor and the feed mechanism.

The closest in technical essence and the achieved result is a grinder-distributor of roughage [2], containing a frame with a horizontal rotating hopper mounted on it, made in the form of two hollow cylinders, which are located at some distance from each other and are covered outside by a fixed bottom with a window . Outside the hopper, a grinding rotor with a vertical axis of rotation is located in the window zone, the working elements of which interact with the material in the hopper, grind it and feed it into the feeder through the discharge neck. The hopper is equipped on one side with a flat wall with a fork grip for loading feed, and on the other hand with a conical wall, a large base adjacent to the cylinder to intensify the process of moving the material in the hopper.

The use of a rotor with a vertical axis in this grinder-dispenser leads to unevenness of the whole process of grinding and distribution due to the inconsistent supply of material to the working bodies. Inconsistency of supply is due to the fact that the rotor with a vertical axis is structurally impossible to locate in the place of the greatest accumulation of material. The use of a rotor with milk of equal length in this grinder-dispenser leads to uneven process due to uneven loading of hammers. When feeding material to the rotor, the first rows of hammers come into operation, and the subsequent ones work idle. When distributing the crushed material into animal feed or bedding, there are cases of clogging of the discharge deflector by the crushed material due to the low kinetic energy of the particles and low air flow.

The proposed chopper-distributor of feeds contains a horizontal hopper made in the form of two coaxially arranged cylinders, interconnected and covered by a bottom with a window, a conical wall adjacent to the hopper with a large base from the opposite loading side, a grinding rotor with hammers mounted outside the hopper in the window area, loading and unloading devices located hardly on axes parallel to the axis of the rotor, while the rotor axis is perpendicular to the axis of the hopper, its hammers are made of different lengths, increasing vayuschiesya in the direction from the center of the hopper, in addition, provided with blades hammers, and at the bottom inside the hopper mounted visor disposed in front of the window in the direction of rotation of the hopper.

This arrangement and design of the rotor allows the separation of the material from the monolith at different levels, and in this case, all hammers interact with the material in the process. The simultaneous operation of the hammers ensures a uniform grinding process. Part of the hammers with attached blades creates the air flow necessary to remove material from the rotor, which prevents the discharge deflector from clogging with crushed material.

Thus, the presence of distinctive features from the prototype, the usefulness and the possibility of implementing the proposed technical solution show that it meets the criteria of an inventive step and industrial applicability.

The inventive chopper-distributor of feed is illustrated in the drawing. In figure 1. shows a chopper-dispenser, figure 2. - view A in figure 1, figure 3. - view BB in figure 2, figure 4 - view In figure 3, figure 5 - view G in figure 2.

The feed chopper contains a hopper 1 mounted on the frame 2. A rotor 3 with hammers is located in the lower part of the hopper with the possibility of grinding and dispensing of material. It consists of disks 4, on the axes 5 of which grinding elements are placed in the form of, for example, hammer tools 6 of various sizes, increasing in length from the center of the hopper. The guide body 7 of the rotor 3 is made curved, for example, along a logarithmic spiral, through which the crushed material is displayed in the feeder animals. The hopper 1 is made of two cylinders 8 and 9 interconnected by elements 10. From axial and radial movement, the hopper is held by support rollers 11 mounted on the frame, and by the axis on which the conical wall 12 of the cylinder 9 is fixed and which allows it to rotate. The loading device consists of a bead 13 mounted on the frame with the possibility of rotation around a horizontal axis and forks. Opening and closing the hydraulic side is carried out, for example, by means of a hydraulic cylinder. The rotor drive is carried out, for example, by means of a V-belt transmission 15 from a tractor power take-off shaft. The drive of the hopper 1 is carried out, for example, by means of a hydraulic motor 14 from the tractor hydraulic system. Performance adjustment is carried out by raising or lowering the adjustable visor 16 with a screw 17. To prevent clogging of the discharge deflector with crushed material, part of the hammers 6 is equipped with blades 18.

Chopper-distributor of feeds is as follows. The material to be crushed (rolls, bales or in bulk) is loaded into the hopper 1, placed on the frame 2, using a hydraulic side with a fork grab 13. In the loaded position, the unit moves to the feed distribution zone, where the drive of the working bodies is turned on. The rotor 3 rotates from the tractor power take-off shaft through a V-belt drive 15, the material is fed into the grinding zone by the hopper 1 with elements 10. Hammer working bodies 6, made increasing in length from the center of the hopper, are installed between the rotor disks 4. They separate the material from the bulk (roll, bale) at different levels, capturing and grinding it. Due to the kinetic energy of the rotating rotor and partly due to the resulting air flow, the material is ejected through the guides of the rotor body 7. Installing the rotor in the lower part of the hopper perpendicular to its axis to increase the area of interaction of the working bodies of the grinder (hammers) with the crushed material, thereby increasing machine performance and uniformity of the grinding process. The capacity of this unit can be controlled by the speed of the hopper or the length of the hammers. The latter is changed by raising or lowering the adjustable visor 16 with the adjustable screw 17.

Using the proposed chopper-distributor of feed will fully mechanize and efficiently perform the process of grinding and distribution of feed, as well as the introduction of litter.
