Paste filling hydraulic support isolation plate

The utility model discloses a paste filling hydraulic support isolation plate, and belongs to a filling hydraulic support. The isolation plate is divided into an upper isolation part, a middle isolation part and a lower isolation part, the upper isolation part and the lower isolation part are connected with sealing strips, extend out along with lifting columns of the supports and lower isolation telescopic jacks to seal coal seam roofs and baseplates of to-be-filled areas, and extend out vertically and laterally to seal gaps between adjacent supports. The upper isolator rises to extrude the upper isolator to seal a gap between the isolation tail beam and the upper isolator; the upper isolation side extends out of two adjacent gaps at the position of the sealing top plate, the lower isolation side extends out of two adjacent gaps at the position of the sealing bottom plate, relative movement of the upper isolation side, the middle isolation side and the lower isolation side can adapt tocoal seam mining height
