Zusammenfassung: | The utility model discloses an end support net-breaking coal caving mechanism with two supports in one group, which relates to the technical field of end supports of fully mechanized caving faces of underground coal mines and comprises a top beam, a swing beam, a net-breaking beam, a shield beam, a coal caving port, a front baffle, a bottom frame, a lifting jack, a supporting arm, a swing jack, a telescopic jack and a cutter block. A top beam is connected to the upper portion of the bottom frame through a lifting jack, and the shield beams are hinged to the left side and the right side of the front end of the top beam respectively. The method has the beneficial effects that the coal caving efficiency is high; coal can directly fall into the reversed loader, manual coal charging is not needed, a coal discharging port is low, and the fall is low when the coal falls into the reversed loader; the whole structure of an original end bracket in which two brackets form a group is not changed, and the end bracket can |
