Abstract

 A feed chopper-distributor containing a feed hopper, outside of which there is a chopper rotor housing made in the form of a disk with chopper elements located on it along concentric circles, a loading and unloading device, the rotor axis of rotation being perpendicular to the hopper rotation axis, characterized in that the rotor blades are installed, and the grinding elements are fixed at an angle to the tangent to the concentric circle and are arranged in a spiral.

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 frame with a horizontal rotating hopper mounted on it. 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 disadvantage of this grinder-distributor is the high energy consumption for the grinding process and the complexity of the rotor drive.

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, which is covered outside by a fixed bottom with a window. Outside the hopper there is a grinding rotor with a horizontal axis of rotation, the working bodies of which interact with the material in the hopper, grind it and feed it into the feeder through the discharge neck.

The installation of grinding elements in this grinder-distributor does not provide the removal of material from the center to the periphery of the rotor, which leads to clogging of the grinding zone.

The blades located on the side of the rotor opposite from the grinding elements do not have a hurling effect on the material, but create a significant air flow, which leads to dustiness of the premises.

The proposed chopper-distributor contains a horizontal feed hopper mounted for rotation and made in the form of two coaxially arranged cylinders, a bottom with a window covering the hopper from the outside, a conical wall adjacent to the hopper with a large base on the opposite side. Outside the hopper, perpendicular to its axis, a grinding rotor housing is installed with the possibility of interaction of the working bodies with the material. The rotor is made in the form of a disk with grinding elements located on it along concentric circles. The rotor knives are mounted at an angle to the tangent to the concentric circle and are arranged in a spiral, and the discharge blades are installed on the periphery of the rotor disk. 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. Thanks to this design, there is a free removal of material from the grinding zone, without clogging.

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. - view A in figure 1.

The feed chopper contains a hopper 1 mounted on the frame 2, a rotor 3 with a horizontal axis of rotation, consisting of a disk 4, on which the chopping elements 5 are installed in the form of, for example, segmented working bodies. Unloading blades are fixed on the periphery of the disk 6. The guide of the housing 7 of the rotor 3 is made curved, for example, along a logarithmic spiral. In the final part of the housing 7 there is a deflector. In the raised state of the deflector, the material is fed to the litter, in the lowered state - to the animal feeder. The hopper 1 is made of two coaxially arranged cylinders and mounted rotatably. From axial and radial movement, the hopper is held by rollers 9, mounted on the frame 2, and the axis on which the conical wall is fixed. The outer surface of the cylinders has spikes and grooves through which rotation is transmitted from the rollers 8. The loading device consists of a side 10 mounted on a frame with the possibility of rotation around a horizontal axis. The opening and closing of the hydraulic side 10 is carried out, for example, by means of a hydraulic cylinder 11. The rotor is driven, for example, by a V-belt transmission 12 from a vehicle power take-off shaft. The hopper is driven, for example, by a hydraulic motor from the tractor hydraulic system through one of the drive rollers.

Chopper-distributor of feeds is as follows. The material to be crushed (in rolls, bales or in bulk) is loaded into the hopper 1, placed on the frame 2, using the hydraulic side 10. In the loaded position, the unit moves to the feed distribution zone, where the rotor drive 3 is turned on. The rotor rotates from the transport power take-off shaft funds through a V-belt drive 12, the material is fed into the grinding zone by the hopper 1. Knives 5 of the rotor 3 separate the material from the main mass (roll, bale), grind it and move it to the periphery of the rotor, which is ensured by the installation angle and location knives in a spiral. From the periphery, the material due to the hurling effect of the blades 6 and, in part, due to the arising air flow is thrown out through the deflector.

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.
