Abstract

This invention relates to grain milling equipment. The purpose of the invention is to simplify the design and increase reliability in operation. The disks 1 and 3 are made with the same notches 14 having curved walls. A part of the cutting ribs made on these walls has a curved shape, and a part is straight. The ball bearing 5 is equipped with two protrusions 6 entering the grooves of the rotating disk with the possibility of rocking motion, which makes it possible to compensate for the possible skew of the disks. 5 il.

The invention relates to equipment for grinding grain, in particular to disk mills, and can be used in personal subsidiary farms for grinding fodder cereals into fodder products for livestock.

The aim of the invention is to simplify the design and increase reliability in operation.

FIG. 1 shows the proposed disc mill, a section along the axis of the drive shaft; FIG. 2 is a view A of FIG. 1; FIG. 3 is a view B in FIG. 1; in fig. 4 shows a section B-B in FIG. 2; in fig. 5 is a section of YYD in FIG. 2

The disk mill contains a fixed disk 1 mounted on the housing 2, a rotating disk 3 fixed to the drive shaft 4 by means of a ball bearing 5 with the possibility of rocking motion. To transfer the torque from the shaft to the disk, the right support 5 is rigidly connected to the shaft and provided with two the protrusions 6, interacting with the slots 7 of the rolling disk. The receiving funnel is intended for receiving the raw material. The disks are covered with a casing 9 with an outlet branch pipe. 10. In the casing, the adjusting screw is installed coaxially with the drive shaft.

11, moreover, in the end face of the adjusting screw and the drive shaft there are made conical recesses, in which the supporting ball bearing is mounted

12. The drive shaft is capable of axial movement, which makes it possible to adjust the size of the gap between the working surfaces of the disks by turning the adjusting screw, which is fixed by the lock nut 13.

The disks with knives and cutting edge-shaped elements are made with the same notches 14 having curved walls, and part of the cutting edges made on these walls of the notches of the disks have a curved shape 15, and some are straight 16. The fixed blade disk has holes 17 in center through which the drive shaft passes and is fed to the working surfaces of the disks.

The mill works as follows.

The source material from the receiving funnel 8 on an inclined surface under its own weight through the hole 17 in the fixed disk 1 enters the cavity formed by the notches 14 of the working disks 1 and 3, where under the action of the cutting ribs having a rectilinear form 16 and centrifugal force enters the zone cutting and as grinding enters the outlet 10.

The size of the finished product is determined by the size of the gap between the fixed and rotating discs. The size of the gap is varied by turning the adjusting screw 11 and is based on the principle that the forces of the cutting elements tend to push the discs apart. There is a gap between the protrusions and the slots.

Claims (1)

Invention Formula Diskova, mill, containing a housing with a receiving funnel, inside which are disposed coaxially facing to each other working surfaces with cutting ribs disks, one of which is fixed to the housing, and the other, movable, by means of a ball-shaped support mounted on a drive shaft, characterized in that that, in order to simplify the design, increase reliability and increase productivity, the ball bearing is made with two diametrically opposite projections, and the movable disk with grooves, in which the projections are located ball bearing with the possibility of swinging movement, and the working surfaces of the disks are made with central recesses extending to each other with curved walls and part of the cutting ribs on them are made curved, and some are straight and protruding above the latter. i7 WadA Fi & 2.
