DEVICE FOR SIEVING OF LOOSE MATERIAL

摘要

FIELD: material screening machinery and equipment. SUBSTANCE: this is used for sieving and disintegration of loose materials for agriculture, mining industry, construction materials industry. Device has sieving surface which is made in the form of longitudinal flexible members secured by their ends to lateral supports. One of these lateral supports can perform reciprocal longitudinal movements in plane of sieving surface. Each of longitudinal flexible members is made in the form of resilient band having two twisted sections with opposite direction of twisting. These two twisted sections are interconnected to each other by rigid coupler made in the form of threaded bush with two cups turned on coupler. Rigidly fastened to bottom of each cup is internal end of nearest section of band. EFFECT: higher efficiency. 1 dwgn
