Bottom plate climbing and gap bridge coal mining machine for extremely thin coal seam

The invention provides a bottom plate climbing and gap bridge coal mining machine for an extremely thin coal seam. A main machine body (1), a left rocker arm (4) and a right rocker arm (9) are arranged between a conveyor (39) and a coal wall (29); the main machine body (1) is parallel to the conveyor (39); a gap bridge (21) is connected with the main machine body (1) through a positioning pin (32), a high-strength screw rod (35) and a hydraulic nut (36) to form a rigid whole body; a guide sliding shoe (30), a coal wall side flat sliding shoe (33) at the bottom of the gap bridge, an operation side flat sliding shoe (34) and a guide hook (37) are used for supporting the weight of the whole machine together; and the left rocker arm (4) is hinged to the main machine body (1) through a left rotary point (5). According to the bottom plate climbing and gap bridge coal mining machine for the extremely thin coal seam, the counter-acting force of the coal mining machine in a working process is reduced; float coal on a working surface is reduced in an actual working process and a stress state of the whole machine is optimized; and the service life of a driving part and a guide part is greatlyprolonged and the aims that one working surface is not damaged and is not overhauled are realized.
