HEADING-AND-SURFACE MINER Russian patent published in 2021 - IPC E21C27/00 E21C27/24 E21D9/10 

FIELD: heading-and-surface miners.

SUBSTANCE: invention relates to mining, namely to heading-and-surface miners, and can be used to carry out mine workings with simultaneous drilling in the roof and wall of the workings degassing holes, technological and for installing anchor support. The harvester includes an executive body, a crawler undercarriage, a conveyor, a berm body, hydraulic equipment, electrical equipment, a drilling rig designed for drilling holes in the roof of a mine, a drilling rig designed for drilling holes in the wall of a mine. Each drilling rig contains a bed, a feeder, a hydraulic cylinder for moving the feeder and a drill rod rotator with a hydraulic motor. In this case, the feeder contains a chain drive with a tensioner and a hydraulic motor, which ensures the linear movement of the rotator in the guide frames of the feeder. In this case, the feeder is installed on the bed with the possibility of linear movement in its guides when the hydraulic cylinder rod moves, which is hinged on the bed and the feeder frame. On the frames of the feeders from the outside of the combine, at least two pointed pins are rigidly fixed, designed to fix the position of the feeders when they are pulled out all the way into the mountain range. The feed bed of the drilling rig is pivotally attached to the mounting bracket of the specified drilling rig with the ability to rotate around the hinges when the rods of two hydraulic cylinders move, pivotally attached to the bracket and the bed, while with the rods retracted, the drilling rig is in the transport position, and when extended, in the working position.

EFFECT: invention ensures the possibility of drilling holes in the roof and wall of a mine working simultaneously with the process of its sinking.
