brake mechanism with a brake travel device. The working bodies 6 are driven into rotation by a drive, wherein they act on the compressed material and the latter is unloaded from the silo. For fixation in a motionless state, the drive of the device is used a brake mechanism. After removing the layer of compacted material j corresponding to the length of the groove in sleeve 7, the braking mechanism is turned off and the working bodies are moved up to the next starting cot. 1 il.

The invention relates to the field of storage and unloading of materials, in particular compacted material in silos.

The aim of the invention is to increase productivity and reduce energy intensity.

The drawing shows a device for unloading compacted material from SESB, general view.

A device for unloading compacted material from silos contains a drive that includes an electric motor 1 freely suspended in the central part of the silo on a rope 2 by means of a bearing housing 3 fixed on the shaft 4 of electric motor 1, a mechanism for moving workers B containing a rope 2 fixed on top of the silo. On the shaft 4 of the electric motor 1, a bracket 5 is rigidly fixed, pivotally connected to the working bodies 6. having a saw-shaped working surface, the ends of which, facing the central axis, have a rounded shape along the radius of the hinge attachment (d), the sleeve 7 is attached to the electric motor 1 through the grooves of which the spokes 8 of the brake mechanism pass with the possibility of axial movement. At the ends of the latter, a rim 9 with an inflatable chamber 10 is rigidly fixed. The device includes a brake movement device consisting of a cable 11 transferred through a roller 12 on which a load 13 is suspended. The cable is attached to the spokes 8 of the brake mechanism.

To the inflatable chamber 10 through the nipple

14 t5 hose with valve 16 is attached.

On the sleeve 7 on the bottom side there is a clamp-stop 17.

The device works as follows.

5 In the central part of the silo on the rope with a winch, the device is mixed from bottom to top.

The working bodies 6 are driven through the bracket 5 by an electric motor 1. The centrifugal forces of the workers open the oprai bi 6, thus loosening the compacted material and raining it out of the silo. Thanks to the rounded shape

5 ends facing the central axis, a constant distance is maintained - meddu rope and working body when the angle of inclination of the latter changes, which eliminates the possibility of jamming

0 when working. Device.

The brake mechanism of the motor housing works as follows. The valve 16 is opened, the compressor is turned on (not shown), and the chamber 10 is blown through the nipple 14 of the booster, which abuts against

material walls., prevents rotation of the motor housing.

After moving the device up

0 over the silo, the length of the groove in the sleeve of the spokes 8 abut against the limiter 17, while the movement of the device is stopped, the valve 16 is turned off, the air is released from

5 of the inflatable chamber 10 through the nipple 14 and the hose 15. At the same time, the adhesion of the inflatable chamber 10 to the inner walls of the silo is weakened, and under the action of the load 13 by means of a cable 11

0 through the roller 12, the brake mechanism moves upward along the axis of the silo. After this, the unloading process is repeated until the silo is completely unloaded.
