| description | The invention discloses a horizontal scissor bottom lifting mechanism. A hydraulic support base comprises a left part and a right part. The left part and the right part are connected by a bridge board, and the gap between the left part and the right part is provided with a shifting rod. The horizontal scissor bottom lifting mechanism comprises two bottom lifting frames, the middles of the two bottom lifting frames are respectively hinged to the left part and the right part, the upper ends of the bottom lifting frames are connected by a bottom lifting jack, and the lower ends of the bottom lifting frames are arranged above the shifting rod. The horizontal scissor bottom lifting mechanism is disposed on the front portion of the bridge board and solves the problem that a thin coal seam bottomlifting mechanism is small and poor in bottom lifting effect.
