From the patent and scientific literature is not known the design of the device for unloading bulk material from the hopper, in which in the plates of the working body under the consoles symmetrically relative to the longitudinal axes of the grooves made in the diaphragms, grooves are made along the hopper and agitators are installed in them in the form of sectors, fixed from the side vertices of intersection of the radii of the sectors to the hinges located on the diaphragms, and on the opposite side are spring-loaded and pivotally supported by rotation hydraulic cylinders installed the outer side of the hopper.

Figure 1 shows a General view of the device for unloading bulk material from the hopper; figure 2 is a section aa in figure 1; figure 3 is a section bB in figure 1; figure 4 - section bb in figure 2; figure 5 - section GG in figure 3.

A device for unloading bulk material from the hopper contains a working body 1 and nozzles 2, 3, 4 with tips 5, 6, 7 for supplying compressed air (pneumatic drive conditionally not shown). The working body 1 is made in the form of steps 8, 9, 10, which are connected at the ends in pairs by diaphragms 11, 12 with the grooves 13 made therein. Steps 8, 9, 10 of the working body 1 are made in the form of plates, located at an angle of 60 ° horizontally and fixed to the vertical walls 14, 15 on the inside of the hopper 16. The lower parts of the ends of the steps 8, 9 are cantilevered with respect to the diaphragms 11, 12. The nozzle 2 is fixed with hinges 17 and the link 18 on the outside of the end wall 19 of the hopper 16, and the nozzles 3, 4 are fixed respectively with a step nirov 20, 21 and backstage 22, 23 from the outside to the working body 1 of the hopper 16. The nozzles 2, 3, 4 are made in the form of a box 24 of a trapezoidal section with a spool 25 located on the side of the smaller base and an elastic nozzle 26 of a V-shape with a longitudinal a groove 27. On the upper parts of the steps 9, 10 symmetrically with respect to the grooves 13 along the hopper, grooves 28, 29 are made in which agitators 30, 31 are installed in the form of sectors. The agitators 30, 31 are connected respectively with cylindrical hinges 32, 33 fixed to the diaphragms 11, 12 on the inside of the hopper, and are supported through hinges 34, 35, respectively, by rods 36, 37 of the lifting and lowering hydraulic cylinders 38, 39 located on the outside of the hopper 16 The rotation of the agitators 30, 31 relative to the hinges 32, 33 counterclockwise is limited by limit switches 40, 41, respectively, and clockwise by stops 42, 43. The agitators 30, 31 are spring-loaded with tension springs 44, 45.

A device for unloading bulk material works as follows.

In the process of unloading bulk material from the hopper include a pneumatic drive attached to the working body 1 of the hopper 16. Elastic nozzles 26 of nozzles 2, 3, 4 are installed in grooves 13 of end wall 19 and diaphragms 11, 12. The angle of inclination of nozzles 2, 3, 4 relative to steps 8, 9, 10 of working body 1 is regulated by the rotation of nozzles 2, 3, 4 relative to hinges 17, 20, 21 and is fixed by the wings 18, 22, 23. Spool 25 is placed in the open position. Compressed air is supplied through the tips 5, 6, 7 to the duct 24, which then passes through the spool 25 and the longitudinal groove 27 of the elastic nozzle 26 and enters the gaps between the bulk material and the working body. At the same time, the hydraulic cylinders 38, 39 are turned on. The rods 36, 37 of the hydraulic cylinders 38, 39 extend and move up the hinges 34, 35 respectively with the agitators 30, 31 along the grooves 28, 29. The agitators 30, 31, rotating counterclockwise relative to the hinges 32, 33, they leave the plane of steps 9, 10. The hydraulic cylinders 38, 39 are turned off when the limit switches 40, 41 are triggered. Under the action of the compressed air flow, the stepped design of the working body and the additional lifting of pieces of material by agitators, the pieces are agitated, drained organ and restoration of gravitational outflow conditions. After restoration of the conditions of gravitational outflow of material, compressed air is turned off, the rods 36, 37 of the hydraulic cylinders 38, 39 under the influence of gravity and the forces of the springs 44, 45 return to their original position, and the lower and upper planes of the agitators 30, 31 are set respectively on the stops 42, 43 and flush with steps 9, 10.

The bulk material is prone to jamming in a closed volume, which makes it difficult to unload. Manual operations to eliminate the clogging of the hopper are ineffective and take a lot of working time. The present invention allows to effectively carry out the process of tedding the bulk material and facilitates its unloading. Thus, the task associated with improving the efficiency of unloading bulk material from the hopper is achieved by the proposed device.
