Abstract

Изобретение относитс  к строительству сооружений с применением гидромеханизации, к горному делу - дл  добычи нерудных материалов, водному транспорту и примен етс  преимущественно на землесосных снар дах. Цель - увеличение производительности самоотводного землесосного снар да путем повышени  консистенции пульпы. Грунтоприемник включает шарнирно соединенные между собой неподвижную 1 и подвижную 2 части корпуса с всасывающим отверстием (ВО), ограждением снизу поперечной решеткой 13. На подвижной части между ВО и местом соединени  подвижной и неподвижной частей 1, 2 снизу закреплен коллектор 4, выполненный с зубь ми 5, в которых установлены сопла 11, расположенные ниже решетки 13 и направленные в сторону ВО. Зубь  5 соединены с коллектором 4 посредством Т-образных направл ющих 6 с уплотнени ми. Решетка 13 установлена с возможностью регулировани  по высоте относительно неподвижной части и имеет скребки-перемычки 14. Струи воды, выбрасываемые из сопел 11 зубьев 5 в сторону наконечника, создают котлован, наполненный пульпой. Котлован за счет движени  грунтоприемника превращаетс  в траншею. Решетка 13 грунтоприемника перемычками-скребками 14 захватывает разрыхленный грунт и направл ет его в зев грунтоприемника. Пульпа всасываетс  и транспортируетс  обычным способом. 2 з.п. ф-лы, 2 ил.The invention relates to the construction of structures using hydromechanization, to the mining industry - for the extraction of nonmetallic materials, water transport, and is used mainly on suction dredgers. The goal is to increase the productivity of the self-suction suction dredger by increasing the pulp consistency. The soil receiver includes a fixed 1 and a movable 2 body parts with a suction inlet (VO) hinged between themselves, a transverse grille 13 at the bottom. A collector 4 with teeth is fixed on the movable part between the VO and the junction of the movable and stationary parts 1, 2. 5, in which nozzles 11 are installed, located below the grating 13 and directed towards the VO. The tooth 5 is connected to the collector 4 by means of T-shaped guides 6 with seals. The grill 13 is installed with the possibility of height adjustment relative to the fixed part and has scrapers-jumpers 14. Water jets ejected from the nozzles 11 of the teeth 5 in the direction of the tip, create a pit filled with pulp. The excavation pit is transformed into a trench due to the movement of the soil receiver. The grate 13 of the soil collector with scrapers 14 captures the loosened soil and guides it to the mouth of the soil receiver. The pulp is sucked and transported in the usual way. 2 hp f-ly, 2 ill.
