Description

The utility model relates to agriculture and can be used in animal husbandry for the preparation and distribution of stalked feed 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, horizontal grinding rotor. The disadvantage of this chopper-distributor is the low reliability of the working process due to insufficient tedding of material, clogging of the material of the feed conveyor and the feed mechanism.

The closest in technical essence and the achieved result is a chopper - 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 interconnected by combs and covered outside by a fixed bottom with a window. Outside the hopper there is a grinding rotor with a vertical axis of rotation, the working bodies of which interact with the material in the hopper, grind it and feed it through the discharge neck to the feeder. 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 presence of connecting combs between the cylinders in this grinder - distributor determines the movement of the crushed

material together with the hopper. This leads to unevenness of the entire grinding process, because the crushed material does not turn over during the operation of the grinder.

The proposed chopper - dispenser contains a stationary hopper, a conical wall adjacent to the hopper with a large base on the opposite side to the load, made with the possibility of independent rotation and equipped with tedders mounted on the wall cantilever along its guide. Outside the hopper, a grinding rotor is installed with the possibility of interaction of the working bodies with the material. On the opposite side from the conical wall of the side, the hopper is equipped with a loading device, and for discharging the crushed material there is an unloading device.

Installing the hopper in a stationary way allows the rotor to move deep into the ground material, which leads to an increase in the area of interaction of the working bodies of the grinder (hammers) with the ground material, thereby increasing the productivity of the machine. Also, this shredder-distributor contains tedders that are installed with the ability to level and expand the shredded material more qualitatively, and thanks to the stationary bunker mounted on the bale, friction forces act on the one hand, and on the other hand, tedders help carry it into rotational motion. All this creates the conditions for intensifying the movement of material inside the hopper.

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

The inventive chopper - distributor is illustrated in the drawing.

In figure 1. shows a side view of the chopper - distributor of feed, figure 2. front view is shown.

The chopper - feed dispenser contains a hopper 1 mounted on the frame 2. The rotor 3 with a vertical axis of rotation is installed in such a way that it can be moved along the guides into the depth of the chopped material. It consists of disks 4 on the axes 5 of which grinding elements are installed in the form of, for example, hammer working bodies 6. The guide of the housing 7 of the rotor 3 is made curved, for example, along a logarithmic spiral, along which the crushed material is fed to the animal feeders. The hopper 1 is made stationary, and its conical wall 10 is made with the possibility of rotation on the rollers 8 with variable speed. On the loading side, the conical wall 10 has feeding tedders 9 mounted cantilevered thereon along the guide cone. From axial and radial movement, the conical wall 10 is held by rollers 8 mounted on the frame 2, and the axis on which the conical wall is mounted, mounted for rotation. The loading device consists of a side 11 mounted on the frame 2 with the possibility of rotation around a horizontal axis. Opening and closing the hydraulic side 11 is carried out, for example, by means of a hydraulic cylinder. The rotor is driven, for example, by a V-belt drive 13 from a vehicle power take-off shaft. The drive of the conical wall 10 is carried out, for example, by means of a hydraulic motor 12 from the tractor hydraulic system, by means of a V-belt transmission 15.

Chopper - feed distributor operates as follows. The material to be crushed (rolls, bales or in bulk) is loaded into the hopper 1, placed on the frame 2, using the hydraulic side 11. In the loaded position, the unit moves to the feed distribution zone, where the drive of the working bodies is turned on. Rotor 3

rotates from the power take-off shaft of the vehicle through a V-belt drive 13, the material is fed into the grinding zone with a conical wall 10 and agitators 9. Hammer working bodies 6 are installed between the rotor disks 4, they separate the material from the main mass (roll, bale), capturing it, feed it into the central part of the rotor 3. Due to the kinetic energy of the rotating rotor and, partly, due to the resulting air flow, the material is ejected through the channel 14. Installing the hopper stationary allows the mouth to move ora deep into the ground material, and the presence of tedders, with a fixed bottom, creates conditions for intensifying the movement of the ground material inside the hopper. 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.
