Description

stump crushing. The plates fixed on the opposite side wall and included in the radial grooves of the rotor blades overlap the grooves and prevent small loose material from flowing out through them, which allows metering.

The execution of the side walls with fixed on || min | n3ih knives and removable plates for disassembling and disassembling and repair

f-fa of Fig. T shows the proposed rotary device for supplying bulk materials, cross section, in Fig.2 - section in Fig 1

The device includes a horizontal cylindrical body 1 with loading 2 and unloading 3 nozzles, in the upper part of which there is a knife 4, and in the center of the rotor 5 with blades 6. On the side wall 7.. Н0 removable, fixed perpendicular to the axis of the rotor 5 of the plate 8, in the grooves of the blades 6 of the rotor 5 On the opposite side wall 9, also in the b1prinner, removable, opposite the blades of the foam, perpendicular to the axis of the rotor 5, additional knives 10 are included in the grooves of the blades 6.

The device operates as follows.

Bulk material coming from the hopper through the loading pipe 2 into the cells of the rotor 5. When the latter rotates, it moves to the discharge pipe 3, where it is poured out of the cells. When large pieces of material protruding above the rotor 5 get into the cells, they are cut

are crushed and crushed under the influence of a knife 4 and blades 6. Large pieces of material that fall into the cells of the rotor 5 and do not protrude above it move freely to the plates 8, where they are cut and crushed, falling between these knives and blades 6 By rotating the rotor 5, the bulk material, together with the crushed pieces, moves to discharge. Additional knives 10 prevent the outflow of fine material from the hopper through the grooves in the blades 6

The proposed rotary device for feeding bulk materials in comparison with the prototype allows for a higher degree of crushing

Claims (1)

Claims 1 A device for supplying bulk material comprising a horizontal cylindrical body with loading and unloading nozzles, a rotor located in the housing and a knife mounted above it, characterized in that, in order to increase the reliability of operation, it is provided with additional knives mounted on the side wall of the perpendicular housing perpendicular to the axis of the rotor, and grooves are made in the rotor blades for the passage of additional knives 2 The device according to claim 1, characterized in that it is provided with plates mounted on the wall of the housing diametrically opposite to the additional knives 3 The device according to claim 1, characterized in that the side walls of the housing are removable Fig 1 FIG. 2
