Abstract

The invention relates to the mining industry and is intended for the classification of bulk materials. The purpose of the invention is to simplify the design and reduce labor intensity during operation. The surface contains individual sieves 1 of elastic material, the transverse edges (PC) of which are bent and fixed with the edges of adjacent sieves in the grooves formed by the walls (C) 4 of the transverse beams 5 of the screen. The fastening PC is made by means of clamping wedges (K) 6, inserted between the PC up to the stops 8. The distance between C 4 is fixed by the clamping bolts 9 and the sleeves 10, which are also the limiting stops for the PC. With the introduction of K 6 between PCs, the latter are clamped to C 4 and deformed. The PC material is pressed into the holes 7 in C 4 to form the protrusions 11, which play the role of hooks in the fixing points of the sieves 1 to the beams 5. When replacing the sieves, K 6 is removed with a grip on the stops 8. 4 Il.

The invention relates to the mining industry, in particular to devices for the classification of bulk materials, with

The purpose of the invention is to simplify the design and reduce the labor intensity during operation.

Fig shows a portion of the screening surface rumble; Figure 2 shows the position of the sieve edges before installing the clamping wedge; in fig. 3 - the same, after installing the clamping wedge; Fig. 4 - screen beam at the installation site of the limiting stop, cross section

The screening surface of the screen includes individual sieves 1 of elastic material, the transverse edges 2 of which are bent and fixed with edges 20 of adjacent sieves in the grooves formed by walls 4 of transverse beams 5 by means of clamping wedges 6 inserted between edges 2 and 3 "In the walls 4 holes 7 are made,

Each wedge is provided with stops 8 on the upper edges of the wall. The walls 4 of the beams 5 are kept from the wedging effort with tension bolts 9. The distance between the walls 4 is fixed by sleeves 30, which are also restrictive stops for the turned edges 2 and 3 o.

When assembling the screening surface 35, the edges 2 and 3 of the adjacent sieves 1 are folded over and inserted into the grooves of the transverse beams 5 up to the stop into the sleeves 10. After that, the clamping wedges 6 are driven in between the edges 2 and 3 to the contact of the lugs 8 with sieve surface

U 15

The installation of the sieves 1 can be performed simultaneously with their stretching between the beams 5. When driving the wedges 6, the edges 2 and 3 are pressed against the walls 4 and they are deformed, during which the material of the edges is pressed into the holes 7, forming the protrusions 11, the Sieve 1 is held in the grooves of the beams 5 due to the friction forces between the surfaces of the walls 4 and the edges 2 and 3, as well as the hooks formed by the projections 11 o

When replacing the sieves, the clamping wedges 6 are removed by gripping the stops 8 with the device.
