Abstract

Usage: in the agricultural and other industries. The device contains a loading hopper, in the housing one above the other there are fixed and movable disks with knives. The fixed disk is made with windows in which the knives are mounted, wherein the angle between the radial axes passing through the cutting edges is 120 °. The cutting edges of the movable knives are parallel to the center line and can be shifted forward in the direction of their rotation. 1 s P. f-ly, 5 ill.

Description

FIELD OF THE INVENTION The invention relates to crushing and grinding devices and can be used in agricultural and other industries.

U

industry.

The purpose of the invention is to reduce energy) and increase grinding efficiency.

In FIG. 1 shows an apparatus for grinding feeds, general view; in FIG. 2 - along arrow A in FIG. 1; on fig. 3 - section B - B in fig. 2; in FIG. 4 is a section BB in FIG.

in FIG. 5 is a section GG in FIG. 4.

The device for grinding feeds has the form of a two-stage cylinder and contains a feed hopper 1 connected by a housing 2 of the crusher working body. In case 2, a fixed disk is mounted

chopping straw. The fixed disk 3 is movable up or down to adjust its position inside the housing 2. A movable disk 7 with its knives 8 is mounted on a shaft of an electric motor b mounted vertically.

The movable disc 7 has impellers 9 for discharging chopped straw from under the cavity of the movable disc 7 through an outlet 10. The device has a base 11.

A device for grinding feed works as follows.

Stalks of straw are loaded into the hopper 1, and from there they pass through the openings of the windows 5 to the stationary disk 3 into the grinding zone. When this straw falls into the cutting zone on the surface of the movable disk 7.

The movable disk 7 is mounted on the shaft of the electric motor 6. When the electric motor 6 is operated by the rotating disk 7, its knife 8 and counter-interaction of the knife 4, the stationary disk 3 cuts off the stem.

Further, the cut straw portion through the surface of the rotating movable disk 7 is discharged into the space between

edge of the outer diameter of the disk 7 and the housing 2.

Dropping occurs due to centrifugal force, as well as under the influence of knives 8. In this case, the cut straw slice enters the cavity under the movable disk 7 and under the action of the rotating wing of the tray 9 on the disk 7 enters the pipe 10, and through it to the outlet.

Knives on the cut interact as follows. The movable disk 7 and its knives 8 rotate in the opposite direction with the knives 4 of the fixed disk 3, while the beginning of the cutting edge of the knife 8 from the center converges at an angle with the beginning of the cutting edge of the stationary knife 4, also from the center. From this point, the alignment moves to the outer diameter of the disc, cutting along the path of the straw stalk. This combination of knives 4, 8 at an angle is ensured by making the cutting edge of the knives 8, shifted forward diametrically axial, and on the movable disk 7 in the direction of rotation and parallel with respect to the same line, and the action of the knives on the cut with one pair is alternately provided by their location on the fixed disk 3 along the line dividing the disks into corners

120 °, and on the movable disk 7 along the line diametrical axial. The cutting edges of the knives 4, 8 are made corrugated, thereby increasing the efficiency of cutting the stems when they interact at an angle.

Claims (2)

1. A device for grinding feed, comprising a housing in which the fixed and movable disks with knives, a hopper and an unloading nozzle, characterized by 1 in that, in order to reduce energy consumption and increase the grinding efficiency, the stationary disk is arranged to interact with each other with windows in which the knives are installed, the angle between the radial axes passing through the cutting edges of the knives is 120 °, and the cutting edges of the knives on the movable disk are parallel to the center line, and the knives are not and the movable disk is installed with the possibility of alternating interaction with the knives on the fixed disk. 2. The device according to claim 1, with the proviso that the cutting edge of the movable knives is shifted forward in the direction of travel. J 5 8-VFig. 2 Fig.Z Fig 4 r-r Figure 5
