The invention discloses a novel shielding full-mechanized mining hydraulic bracket for an extremely thin coal bed. The key of the full-mechanized mining of the extremely thin coal bed is the adaptability of full-mechanized mining equipment. When the mining of the extremely thin coal bed is carried out by the traditional method and process, supporting equipment for the working face of the extremely thin coal bed cannot overcome restrictions. The novel shielding full-mechanized mining hydraulic bracket for the extremely thin coal bed has the characteristics and performance of the common four bar linkage shielding hydraulic bracket, and mainly comprises a support cylinder, a top beam and a base which are arranged at two ends of the support cylinder, and a cylinder hinged at the rear end of the top beam; the place and state of the top beam are adjusted through the hinged cylinder; and the main motion of the bracket depends on two kinds of cylinders to sufficiently complete the state control of the whole bracket. The magnification ratio of the upright posts is amplified, and simultaneously the bracket has the advantages of high effective support load, high support strength, reliable stabilizing mechanism, consideration of the roof condition of the thin coal bead and suitability for factors which influence the behavior of the tight roof high-strength ground pressure, fills up the blank in the field of support which is most important for the full-mechanized mining of the extremely thin coal bed, and creates preconditions for realizing automatic machine following and other unmanned automatic working faces of the extremely thin coal bed.
