Изобретение относитс к устройствам дл разделени сыпучих материалов по крупт Ности и может быть использовано в горнодобывающей промышленности, промышленности строительных материалов, при обогащении полезных ископаемых и в других област х народного хоз йства.The invention relates to devices for separating bulk materials according to Nosti Crout and can be used in the mining industry, the building materials industry, in mineral processing and in other areas of national economy.

По основному авт. св. № 845878 известно ленточно-струнное сито, содержащее раму с опорами и эластичные ленты, снабженные периодическими выступами и закрепленными в опорах упорными утолщени ми с выступами. С целью повышени срока службы сита путем устранени взаимодействи лент в местах защемлени опора содержит жестко закрепленные на раме пластины , втора из которых со стороны лент выполнена Г-образной формы и ее верхн полка направлена в сторону первой пластины 1. According to the main author. St. No. 845878, a string-string sieve is known, comprising a frame with supports and elastic bands, provided with periodic protrusions and fixed in supports with retaining thickenings with protrusions. In order to increase the service life of the sieve by eliminating the interaction of tapes at the points of pinching, the support contains plates rigidly fixed on the frame, the second of which is L-shaped from the tapes side and its upper shelf is directed toward the first plate 1.

Недостатком известного ленточно-струнного сита вл етс недостаточна надежность креплени и трудоемкость монтажа.A disadvantage of the known ribbon-string sieve is the lack of reliability of attachment and the labor intensity of the installation.

Целью изобретени вл етс повышение надежности креплени лент .путем повышени устойчивости крепежных утолщений в опорах.The aim of the invention is to increase the reliability of fastening the tapes. By increasing the stability of the fasteners in the supports.

Цель достигаетс тем, что в предлагаемом ленточно-струнном сите ленты соединены попарно или по три. Это существенно повышает устойчивость упорных .утолщений при раст жении и установке лент в 5 опорах.The goal is achieved by the fact that in the proposed tape-string screen the tapes are connected in pairs or three. This significantly increases the stability of resistant thickenings when stretching and installing tapes in 5 supports.

Ленты могут быть заранее соединены попарно или по три в узле выступ- отверстие , при этом повышаетс жесткость при изгибе и их устойчивость в опорах при нат жении .The tapes can be pre-connected in pairs or three in a knot-hole assembly, with this increasing rigidity during bending and their stability in the supports under tension.

На фиг. 1 изображено предлагаемое ленточно-струнное сито, вид спереди; на фиг. 2, 3 и 4 - варианты сита.FIG. 1 depicts the proposed tape-string sieve, front view; in fig. 2, 3 and 4 - sieve options.

Claims

The belt-like sieve includes pais mu 1 with supports made in the form of mutually perpendicular plates 2 and L-shaped plates 3 rigidly mounted on frame 1 and forming an inclined groove between them. In the supports by means of stop thickenings 4 tapes 5 and 6 are fixed in pairs (see Fig. 2). The thrust pins 4 of the belts 5 and 6 are provided with openings 7 at one end and protrusions 8 at the other and are directed towards the adjacent belt. In this case, the protrusions 8 of each of the belts 5 and 6 pairs are inserted into the holes 7 of the stop thickenings fixed on opposite supports. In the second embodiment (see Fig. 3), the fastener nubs 4 of one of the strips forming pairs 9, 10 are made at both ends with holes 11, and the other with corresponding protrusions 12. In the third embodiment (see Fig. 4) of the tape 13, 14 and 15 are installed in supports of three. In this case, the thrust bulbs of the extreme tapes 13, 15 are made at both ends with openings 16, 17, and the middle tapes 14 with protrusions 18, 19 directed to the sides of the tapes 13, 15. The string-string sieve works equivalently for all three options. In the tensioned state, the protrusions .8, 12, 18, 19, inserted into the holes 7, 11, 16, 17, provide for the connection and pairwise (or three) interaction of the resistant thickenings of adjacent tapes. The invention will improve the reliability of fastening tapes in screens for fine screening, as well as simplify the process of their installation in supports. Claims 1. Ribbon sieve according to the author. St. No. 845878, characterized in that, in order to increase the reliability of fastening the tapes by enhancing the stability of the fastener fasteners in the supports, the tapes are installed in the supports in pairs, and the resistant thickenings at one end of each of the tapes in a pair are made with holes perpendicular to its plane, on the opposite, corresponding to the shape of the holes with protrusions directed toward the adjacent tape.

2. Sieve on auth. St. No. 845878, characterized in that, in order to increase the reliability of fastening the tapes by enhancing the stability of the fastener thickenings in the supports, the tapes in the supports are installed in pairs, the fastening thickenings of one of the tapes of the pair being made with holes at both ends, and the other tape with projections, corresponding to the shape of the holes And directed towards the latter.

3. Sieve on auth. St. No. 845878, characterized in that, in order to increase the reliability of fastening the tapes by increasing the stability of the fasteners in the supports, there are three tapes in the supports, with the fastening fasteners of the extreme tapes made at both ends with holes, and the middle with protrusions corresponding to the shape holes extreme tapes and directed toward the latter.
