CUTTING HEAD OF A COAL COMBINE FOR THIN PLASTES

摘要

The invention relates to a cutting head coal miner for thin layers, which is used, in particular, to develop coal seams of low power. The cutting head of the coal miner (1) on the side of the mine is guided by two support shoes (8 ', 8 "), which are fixed in the end sections of both cross-arms (7', 7") on the side of the mine, with one cross bar (7 ' ) is fixed on the frame (2) of the head rigidly, and the other yoke (7 ") is articulated, and lifting and lowering are performed by means of the side working cylinder (11), which is placed in the holder head (12) installed on the end of the frame (2). pivotally on the side of making the skeleton (2) of the head and congruently The guide holder (13 ") relative to the side cross member (7") is equipped with a half loop (15) for fastening the side working cylinder (16), the second end of which is placed in the holder (17) of the head frame (2). The frame (2) of the head contains at least one guide (18) localized on the production side, which, according to the principle of gravitational forces, interacts with the guide bar of the nozzle of the downhole conveyor.
