Description

The invention relates to multi-roll roller grinding machines for grinding grain BFx products with a larger diameter roll surrounded by several smaller diameter rolls.

In the proposed machine, the bearings of the rolls surrounding the larger diameter roll are placed in an arcuate guide, with free movement in it, except for the lower one, fixedly mounted, with the aim of mutual pressure of the rolls by the effect of their weight. The two outermost rolls are for a larger diameter roll, and the middle roll is not in contact with it, in order to give the processed grain four passages.

The schematic drawing shows a side view of a multi-roll roller machine.

On the frame 5, four rolls are reinforced, of which roll 4 has a larger diameter than the two extreme rolls 1 and 3 of the same diameter, and the middle roll 2 gets a diameter less than rolls 1 and 3 Bearings 8, 9 and 10 rolls 1, 2 and 3 are inserted into an arcuate guide 19, wherein the bearing 10 is fixed-fixed, and the bearings 8 and 9 of the overlying rolls can move freely in it. The rolls 1, 2 and 3 are in contact with each other under the action of a robust weight and, in addition, can be pressed from above: by means of a device 18 with a spring. Roller 4 is in contact with rollers 1 and 3 and is pressed against them by the action of a spring 11 placed between the bearing 7 and the pressure screw 12.

The roll 4 is driven into motion from the pulley 20 worn on the roll axis, and then the movement is transmitted by a cross-belt through the pulleys 16 and 17 rolls 1 and 3. To create a differential one. speeds pulley 20, respectively rolls, are larger than pulleys 16 and 17. From pulleys symmetrical to pulleys 16 and 17 and seated on their axles, rotation is transmitted by means of cross-belts to double pulley 15, the diameter of which, respectively roll 2, is smaller than diameter pulleys 16 and 17. Rotation can be transmitted using gears or any other gear. The grain is fed to the rolls by a conventional tool, retracted by the rolls 1 and 4 and milled. For better grinding, the roll T is grooved. The milled grain is thrown out with great force and the flap 22, which is tightly attached to the roll 4, is directed to the roll 2, is drawn in by the rolls 1 and 2 and is mined a second time. To ensure that the grain is pulled in, the axis of the roll 2: is located slightly below the axis of the roll 4.

After grinding, the grain is thrown out and the flap b is directed to the place

the contact between rolls 2 and 3. The shield b stands very close to the roll 2, facilitating the movement of grain, which, hitting the roll 3, is drawn in by it. and grinds, and then roll 3 is transferred on its surface and is repurposed for the fourth time by rolls 4 and 3. Oanina 5 is provided on both sides with doors 21; There are openings in the upper doors for inserting inclined plates guiding the grain. Flaps "must be pressed against the rollers. So that the grain is not able to wake down.

The subject matter of the invention.

 1. Multi-roll roller machine for grinding grain products with a larger diameter walled, surrounded

several rolls of a smaller diameter, differing in that the two extreme one roll diameter of 1.3 relates B1ElNa 4 of a larger diameter, and cf the roll 2, smaller than the rolls of 1.3 cm, are placed between the latter and in contact with them, to give the processed grain passage of passage. 2. The form of the roller mill according to claim 1, characterized in that the bearing 10 of the lower roll is fixed forwards, and. bearings 8, 9 overlying; rolls are placed in an arcuate guide 19 with free movement in it, for the purpose of mutual pressure of the rolls 1, 2, 3 by the action of their own weight, while for pressing between the rolls 1,4, 3 serves a device consisting of a spring 11 and pressure screw 12.
