Abstract

The invention relates to the technique of class 1 of loose materials by size class and m. Used in various industries. The purpose of the invention is to improve the quality of the classification and the reliability of the device operation by reducing the reciprocal beat of the upper 10 and lower 11 infinite rod cloths (PP). On frame 1, drive shafts (B) 2.3 are installed with sprockets 4.5 with the same number of teeth and guide pulleys (W) 6.7, freely mounted on B 2.3. At the same time, B 3 is installed outside the circuit of the PP 10.11 in the slots 15 with the possibility of translational adjustment for adjusting the gaps between the rods of the PP 10, 11. The latter are set each above i sl /

The invention relates to the technique of classifying bulk materials according to size classes and can be used in various industries.

The aim of the invention is to improve the quality of classification and reliability of the device by reducing the mutual beating of the upper and lower bar sheets,

Figure 1 shows a diagram of the sorting device; Fig. 2 shows the node I in Fig. I (a variant of the arrangement of the lines of the bars of the upper and lower blades).

The sorting device includes a frame 1, drive shafts 2, 3 fixed on it with sprockets 4, 5 with the same number of teeth and with guide pulleys 6, 7., supporting pads 8, additional supporting pulleys

9, located on the pulleys and sprockets, the screening surface, imprinted in the form of two rod cloths

10.11 mounted one above the other with the possibility of movement in one direction. The rods 12, 13 of the webs 10, 11 form the calibrating I4 illuminators. The leading for the lower (inner) blade 11 is the shaft 2 with an asterisk 4, and for the upper (outer) blade 10 the leading shaft is 3 CQ with an asterisk 5 mounted outside the contour of the two bar blades. The pulley 6 on the shaft 2 and the pulley 7 on the shaft 3 are mounted loosely and have diameters different from the diameters. corresponding leading stars 4 and 5 for the thickness of the chains of rod cloths, taking into account the required gap between them. Shaft 3 is installed

in slots 15 with the possibility of progressive installation movement for adjusting the gaps between the rods 12, 13 of the webs. The shaft 3 can be moved to the right or left, with the result that the rods 12 of the upper web 10 are shifted relative to the rods 13 of the lower web 1I.

The drive is made in the form of a drive sprocket 16 mounted on the drive shaft 2 connected by a chain transmission 17 with an asterisk 18 mounted on the shaft of the engine 19 and gear

5 wheels 20, 21 installed with the possibility of interaction on the drive shafts 2 and 3. Gears 20, 21 are made with the same number of teeth.

0 Guides 22 support the upper working branch of bar stock. The receiver 23 serves to collect the fines passing through the calibrating gaps 14.

The device works as follows.

The bar blades 10 and 11, moving at the same speed, pass a fine fraction (passage) through the calibrating gaps 14 into the receiver 23, and a large fraction (descent) comes off the surface of the upper blade 10.

The mutual position of the bars 12 and 13 of the upper and lower webs 10, 11

 fixed by asterisks 4 and 5, the position of which, in turn, is fixed due to the fact that shafts 2 and 3 are connected by gear wheels 20 and 21. By changing the position of shaft 3 relative to shaft 2 by moving nests 15c by shaft 3 The reciprocal position of the lower and upper webs 10 for adjusting the calibrating gaps is formed by bars 12 and 13 of these webs. Increasing the center-to-center distance between the gears 20 and 21 of the gear drive when the shaft is moved to the right or left is prevented by installing shims under the sockets 15. It is also necessary to adjust the tension of the bar blades 10 and 11 with each adjustment of the gaps 14 to increase the accuracy of classification rods 12, 13 should be installed longitudinal elements with a blade corresponding to the required size of the fines fraction. When sorting the root-and-vegetable crops, these elements, as well as the rods 12, 13. of the webs 10, 11, should be rubberized or coated with a polymer material to reduce their damage.
