The gears 6 and 7 can rotate relative to the shaft 4. The wheels 6 and 7 are interconnected by gear-bevel gear, consisting of bevel gears 8 and 9 and intermediate bevel gears 10, in which bevel wheels 8 and 9 are rigidly fixed on wheels 6 and 7, but still The axles of the gears 10 are rigidly connected to the lid 2. The gears 11 are rigidly mounted on the leash 5, the leashes 12 are rigidly connected to the wheels 13 and 14. In the zadeapenki with the wheels 11 there are wheels 15 that are fixedly mounted Leads 5 and G2 can be filled together with partitions separating the working area of the device from the driving one.

The device works as follows.

When the central shaft 4, which is rigidly connected to the leash 5, rotates, the wheels 13 and 14 roll around the BOKpyt of the central wheels 6 and 7, creating moments of force on them that are perceived by the conical gear. The movement from wheels 13 and 14 is transmitted to the drivers 12. The drivers 12 mix the drive shafts with agitators 3, which rotate around their own axes by running wheels 15 around the wheels 11. As a result, the agitators receive a complex movement consisting of moving their axes along the cycloidal trajectories m and rotation around the axes.

In this case, various variants of the apparatus operation are possible depending on the resistance to movement of the left and right parts of the agitators arising in the stirred mass. If the resistance on the left and right side agitators is the same, then on the central wheels 6 and 7, identical in magnitude and moments of forces occur, which are perceived. intermediate bevel gears 10 and mutually balanced. In this case, the wheels 6 and 7 remain stationary.

If the resistance of the left and right mixers is due to some conditions (the density of materials is different, the presence of lumps,

As a result of changing the speeds of lying of the wheels 6 and 7, the dacloidal motion path of the agitators changes so that they tend to either bypass the zone with the weathered resistance or pass it with a lower speed with less power and, accordingly, less local heating of the mass.

When the mixers leave the zone of greater resistance, the parameters of their movement take on their original values.

Thus, the presence in the gear-lever mechanism of two gears 6 and 7 freely mounted on the central shaft and connected to each other by a gear-bevel gear allows self-regulation of the speed of rotation of the dresser and the trajectories of their movement, which ensures the most rational operation of the device.
