Abstract
Изобретение относитс к землеройным машинам, в частности к рабочим органам карьерных роторных экскаваторов, примен емых на открытых разработках полезных ископаемых. Цель - снижение энергоемкости экскавации крепких пород за счет разрушени грунта путем изгиба. Рабочий ор: ган включает установленный на раме 8 ротор 1 с размещенными на периферии ковшами 2, св занными между собой дугообразными элементами (Э) 3. На них равномерно расположены режущие Э 4 и шарошки 5. Стороны дугообразных Э 3, обращенных к забою, имеют закрепленные на них зубь 7. При перемещении вдоль забо роторное колесо вращаетс и режущие Э 4 прорезают в забое дугообразные щели. Шарошки 5 вход т вслед за Э 4 в щели и воздействуют на боковые стороны образовавшихс дугообразных выступов в направлении от забо , выламыва куски этих выступов. Просыпавшийс экскавируемый материал зачерпываетс ковшами 2 при дальнейшем движении ротора 1. 1 з.п. ф-лы, 3 ил. нслThe invention relates to earthmoving machines, in particular, to working bodies of mining rotary excavators used in open pit mining. The goal is to reduce the energy intensity of excavation of hard rock due to the destruction of the soil by bending. Worker: gan includes rotor 1 mounted on frame 8 with buckets 2 placed at the periphery and arcuate elements connected to each other (E) 3. They are uniformly arranged with cutting E 4 and cones 5. The sides of arcuate E 3 facing the face have the teeth 7 fixed on them. When moving along the bottom, the rotor wheel rotates and the cutting E 4 cut arcuate slots in the bottom. The shredders 5 follow in E 4 into the slots and act on the sides of the arcuate protrusions formed in the direction from the bottom, breaking out the pieces of these protrusions. The excavated material that has spilled is scooped by buckets 2 upon further movement of the rotor 1. 1 Cp f-ly, 3 ill. nsl
