The device contains nozzles 1 with a discharge window 2, hinged 5.,. ..V: -V --.- v -;. ;; connected to the mine. On the nozzle 1 is mounted sealed chamber 5 in the form of a cylindrical sector. On three sides of the lower end of the nozzle 1 is installed a sealing cuff. On the hinge side, 3 nozzles 1 are connected to the shaft with a flexible element. A cage 11 is installed in the mine with a seal around its perimeter. The cage 11 rises to the upper position under pressure in the cavity 14, then is locked with a retainer.

Of (5, the implication relates to the pneumatic lifting and transport machinery, in particular, to devices for unloading the mine hoist cage, and can be used when transporting bulk materials.

The purpose of the invention is to increase the reliability of the device.

Figure 1 shows the device 8 the process of lifting the cage, a General view; figure 2 - the same, in the process of unloading; on fig.Z - section aa in figure 1; figure 4 - node I in figure 2.

The device for unloading the stand of a pneumatic elevator contains nozzles 1 with a discharge window 2, installed; pivotally by means of a hinge 3 at the upper end of the shaft 4. Pa nasadr 1 mounted a sealed chamber 5, made in the form of a cylindrical sector, and the axis of the hinge 3 is aligned with the center of curvature 1 of the cylindrical wall 6 of the chamber 5. On three sides of the lower end of the nozzle 1 of the attachment; ., chag ruzku mine4. A sealing cuff 7 is in contact with the cylindrical wall 6 and the side walls 8 of the chamber 5 from the inside. From the hinge 3 of the nozzles 1, it is connected to the shaft 4 by a flexible element 9 having compensating holes and 10. In the shaft 4, the stand 1 I is movably mounted 12 along the perimeter, and the nozzles 1 at the top end have a latch 13. The cavity 14 under the cage 11 is connected to the air chamber to the charger (not shown).

The device works as follows: pelvis.

A cage is loaded: 1 rises up under the action of overpressure in cavity 14. At the same time nasl, p, o1

Claims (2)

Formula iso The device for p maxTfioro pneumatic lifting of nozzles with unloading increase is reliably provided with an airtight cylindrical section on the wall of the nozzle opposite to the load, while turning the nozzle around the hinge with the center of the rim of the chamber // ........... Chag Ruzku on mine.4. I plops mine 4 and forms its continuation. After reaching the cage I1 of the upper end of the nozzle 1, it locks with a latch 13. Air from the cavity 14 enters the chamber 5, so that the nozzle 1 with the cage 11 rotates around the axis of the hinge 3 towards the discharge window 2. At the same time, the load is poured out of the cage 11 or rolled out through the window 2 beyond the limits of the nozzle 1. In the process of turning the nozzle 1, the walls 6 and 8, the cuff 7, the seal 12 and the element 9 prevent air leakage from the chamber 5, and the slots 10 compensate for the displacement of the nozzle 1 relative to the shaft 4. After unloading the cage 11, the pressure li of the cavity 14 drops (the air-blower is turned off) and the nozzles 1 under their own weight turn to their original position. The latch 13 is turned off and the cage 11 is lowered down under Chag Ruzku on mine.4. Invention Formula A device for unloading the maxTfioro stand of a pneumatic elevator containing nozzles with an unloading window, characterized in that, in order to increase reliability of operation, it is equipped with a sealed chamber in the form of a cylindrical sector fixed on the nozzle wall on the side opposite to the loading window rotation in the direction of the discharge window around the hinge, whose axis is aligned with the center of curvature of the cylindrical wall of the chamber. // x 9g one ( /. uz.
