Description

The invention relates to the field of agriculture, and in particular to devices for grinding feed.

A device for grinding coarse feed of a roll billet is known, comprising a hopper with a chopping tool and an unloading conveyor on a frame with a chassis, characterized in that the hopper is cylindrical, vertical, at the bottom of which is a chopping tool made in the form of a disk along the axes of which alternately located vertical and inclined knives installed at an angle of not more than 45 degrees to the horizontal surface of the disk, and in the axial space horizontal knives are radially located, in pepper diamond-shaped section which are arranged grooves (RF patent №2530811, 13.05.2013).

A disadvantage of the known device is the lack of a uniform, oriented feed roll into the hopper.

Known distributor-grinder roll bales, which contains a working chamber with a drive shaft, on which are located the disk and the additional disk, moved relative to each other, gear grinding elements and the unloading element. The optional drive has an optional drive. Drive shafts with discs are mounted opposite each other with the possibility of oncoming movement and have needles for fixing the roll bales. The disks have radial through diamond-shaped holes, next to which gear grinding elements are parallelly arranged at an angle of 45 degrees to the surface of the disk. A conveyor located under the working chamber was used as an unloading element (RF patent No. 2542120, 10/22/2013).

A disadvantage of the known distributor-grinder of roll bales is difficult to provide pricking of the roll strictly in the center on both sides of the roll, which causes poor-quality grinding of feed material.

A low-energy roll distributor-grinder is known, comprising a hopper located on a frame with a running gear, inside of which there is a cone-type working body with two-bladed grinding segments, in the lower part of which there are blades creating an air flow for transporting the crushed material through the air duct. When the working body rotates, the feed to be crushed, falling on the horizontal and vertical cutting edges of the segment blades, is first compacted, and then, due to sliding, it is cut in the longitudinal-transverse direction. The crushed portions of feed are pushed through the gap into the storage tank, where under the influence of the air flow created by the blades, the feed passes through the air duct to the feed table (Frolov V.Yu. Low-energy-intensive roll grinder / V.Yu. Frolov, D.P. Sysoev / / Effective animal husbandry. - 2014. - No. 9. - S. 9-10. - prototype).

A disadvantage of the known device is the unoriented intake of feed formed in rolls.

The technical result of the invention is to ensure uniform feeding of the bale for grinding, improving the quality of feed by grinding the material to the level of zootechnical requirements.

The technical result is achieved by the fact that in the distributor-grinder of feed formed in rolls containing on the frame with the chassis a cylindrical vertical hopper; a cone-type grinding working element located in the bottom of the hopper, on the working surface of which chopping two-plane arc profile segments and slotted holes are installed, as well as a blade wheel located in the discharge duct, according to the claimed invention, the inner surface of the hopper is equipped with screw winding; moreover, the cylindrical hopper in the axial direction is equipped with a needle for pricking roll bales, which is fixed using bearings under the body of the grinding working body; the cone-type grinding working body and the impeller are fixed on the needle to ensure their rotation by means of a pulley from the drive; while on the surface of the grinding working body along the axes of the working surface grinding segments are attached to a two-plane arc profile, and horizontal gear grinding elements are installed radially in the center space, in the cross section of which there are rhomboid openings.

Such a constructive solution allows to improve the quality of the feed due to the uniform feed of the roll with the help of a needle and a screw coiling guide, as well as the fact that the material is cut in two planes by grinding two-plane arc profile segments and gear grinding elements.

The invention is illustrated by the drawing, in which Fig. 1 shows a general view of a feed chopper-distributor formed in rolls, a side view, in Fig. 2 - a hopper (in section), in Fig. 3 - a cone-shaped grinding working body, in Fig. 4 - view aa with a vertical section of a gear grinding element, in FIG. 5 a two-plane grinding segment.

The distributor-grinder of feed formed in rolls consists of a vertical, cylindrical hopper 1 (Fig. 1) placed on a frame with a chassis 5 (Fig. 1), along the inner perimeter of which there is a screw winding 8 (Fig. 1), in the cone-type grinding working element 3 (Fig. 1) is located on the bottom of the hopper, the grinding 13-segment grinding two-plane arc profile is fixed along its axes (Fig. 3), and horizontal gear grinding elements 11 are radially made in the interaxal space of the disk’s working surface (Fig. 3) ), in the cross section of which rhomboid holes 12 are located (Fig. 3), the cylindrical hopper in the axial vertical direction is equipped with a needle 7 (Fig. 1), fixed with bearings 9 (Fig. 1) under the body of the grinding working body 3 (Fig. 3). one); while the cone-type grinding working element 3 (Fig. 1) and the impeller 4 (Fig. 1) are fixed on the needle from the drive of the pulley 10 (Fig. 1), and is also equipped with an unloading duct 6 (Fig. 1).

The dispenser-grinder operates as follows.

A monolith in the form of a roll bale 2 (Fig. 1) is fed into a vertical cylindrical hopper 1 (Fig. 1), placed on a frame with a running gear 5, with screw winding 8 (Fig. 1), pierced by a needle 7 (Fig. 1) . Due to the interaction of the roll bale with winding 8 (Fig. 1) and the forces of gravity, the bale is forcibly fed to the grinding working body of the cone type 3 (Fig. 1). When the material interacts with gear grinding elements 11 (Fig. 3) and grinding two-plane arc profile segments 13 (Fig. 5), grinding occurs both along and across the fibers. The crushed material enters the diamond-shaped holes 12 (Fig. 4), from where it is fed through the impeller 4 (Fig. 1) into the discharge duct 6 (Fig. 1), through which it is loaded into the animal feeders.

The proposed design in comparison with other technical solutions has the following advantages:

- uniform impact on the material in the longitudinal-transverse directions (multi-plane cutting);

- reducing the energy intensity of the machine due to cutting with sliding and transporting feed to the feeders or bedding in the stalls with an air stream;

- improving the quality of grinding;

- increase operational reliability and service life.
