Abstract
Изобретение относитс к машиностроению , преимущественно к рабочим органам траншейных экскаваторов. Целью изобретени вл етс повышение производительности при разработке липких грунтов путем улучшени очистки цепи от грунтов. Раоочий орган траншейного экскаватора включает цепь с несущими и соединительными 5 звень ми, передние 7 и задние В пальцы,на которых установлены кронштейны 9 с площадками 10 с резцами 11. Задний по ходу цепи торец каждой площадки 10 смещен относительно оси заднего пальца 8 в сторону последующего соединительного звена на величину, равную 0,1-0,3 шага цепи. Кронштейны 9 установлены на передних 7 и задних 8 пальцах каждого несущего звена. Площадки 10 размещены с шагом, равным двум шагай цепи. В процессе работы площадки 10 утшрают- с в грани последующих соединительных звеньев и обеспечивают стабильное положение цепи. 1 з.п. ф-лы, 3 ил. (ЛThe invention relates to mechanical engineering, mainly to the working bodies of trench excavators. The aim of the invention is to increase productivity in the development of sticky soils by improving the cleaning of the chain from soils. The working organ of a trench excavator includes a chain with bearing and connecting 5 links, front 7 and rear fingers, on which brackets 9 with pads 10 with cutters 11 are mounted. The end end of each platform 10 along the chain is displaced relative to the axis of the rear finger 8 to the next connecting link by a value equal to 0.1-0.3 chain pitch. The brackets 9 are mounted on the front 7 and rear 8 fingers of each carrier link. Sites 10 are placed with a step equal to two steps of the chain. In the course of operation, the platforms 10 are buried in the edges of the subsequent connecting links and ensure a stable position of the chain. 1 hp f-ly, 3 ill. (L
