After the manufacture of a number of experimental stone -cutting machines at the factories of Ukraine and the relevant tests, their Ministry of Construction and Road Engineering manufactured a prototype of the system of the system from the design bureau in 1948 according to the drawings of the design bureau. M. Zilber-Plit for open developments. The machine was tested at the Buldynsky factory of wall materials (Odessa region) and was accepted for serial production. The annual performance of one combine is 64,000 m3 of mountain mass per year. Universal widelyflowing stone -cutting combine combine is designed to cut the piece stone directly from the open -up arrays of the shells, saw limestones, marls, tuffs and other stones of various sizes, for example 38x38x21.5 cm, 51x38x18 cm 79.5x12x39 cm and t. D. For one installation of the rail track, the combine cuts the layer along the width between the rails of 2850 mm, in height of 395 mm and the length equal to the length of the site. Unlike other existing stone -cutting machines, the combine has the following advantages.1. In the production of vertical and horizontal. The harvester of the harvester of the combine works on the principle of continuous action, without idle moves (the cutting tool works with direct and reverse move along the entire length of the site).2. While two or three cars are required for the production of three operations, the combine performs all these stones cutting with one tool, namely: a) cutting of the lane of the stone along the width of the face (the formation of the length of the piece stone); b) trim from below parallel to the face ( the formation of piece stone width); c) the segment in height of the stone is also parallel to the face (t. e. The final separation of piece stone from the array).
