Abstract

Изобретение относитс к горному делу, а именно к струговым агрегатам дл добычи угл подземным способом. Цель - упрощение конструкции и повышение эффективности выемки за счет снижени энергоемкости разрушени средней части пласта. Исполнительный орган включает верхнюю 1 и нижнюю 2 вертикально замкнутые кольцевые направл ющие (Н), равномерно распределенные по длине Н 1, 2 струговые каретки (СК) 4 с резцовымми головками (РГ) 5, бесконечный т говый орган с ветв ми 11, 12 и дополнительный элемент дл разрушени средней части пласта. СК 4 установлены на Н 1, 2 с возможностью перемещени приводами. Консоль 8 закреплена на одной из РГ 5 СК 4 и смещена в сторону Н к безрезцовой стороне РГ 5. При перемещении вдоль забо РГ 5 СК 4 производ т отбойку полезного ископаемого в верхней и нижней част х пласта. При этом средн часть пласта ослабл етс горным давлением и разрушаетс резцами 9 консоли 8 с некоторым отставанием от верхней и нижней частей пласта. 3 ил.The invention relates to mining, namely to plow units for coal mining by the underground method. The goal is to simplify the design and increase the efficiency of excavation by reducing the energy intensity of the destruction of the middle part of the reservoir. The actuator includes upper 1 and lower 2 vertically closed annular guides (H) evenly distributed along the length H 1, 2 plow carriages (SC) 4 with cutting heads (WG) 5, an endless traction body with branches 11, 12 and additional element for destruction of the middle part of the formation. CK 4 is mounted on H 1, 2 with the possibility of movement by drives. Console 8 is mounted on one of WG 5 SC 4 and shifted towards the H side to the cutting side of WG 5. When moving along the bottom of WG 5 CK 4, mineral is crushed in the upper and lower parts of the formation. At the same time, the middle part of the formation is weakened by rock pressure and is destroyed by the incisors 9 of the console 8 with some lagging behind the upper and lower parts of the formation. 3 il.

Claims

Claim

The executive body of the front aggregate, including vertically closed annular guides on which plow carriages with cutting heads and additional elements for destroying the middle part of the reservoir and end drives are mounted with the possibility of movement, characterized in that, in order to simplify the design and increase work efficiency by reducing the energy intensity of the destruction of the middle part of the reservoir, additional elements for the destruction of the middle part of the reservoir are made in the form of a console with cutters, which is fixed and on one of the carriages plow turning tool heads, wherein the console with cutters biased towards the guide ring.
