| description | The utility model relates to a hydraulic support with a rear sealing function for coal mine paste filling, which comprises a four-bar mechanism, a lower sealing beam hinged to the tail end of a bottom beam of the four-bar mechanism, an upper sealing beam hinged to the tail end of a top beam of the four-bar mechanism, and a first driving device hinged to the bottom beam and used for driving the lower sealing beam to rotate. The front side face of the upper sealing beam abuts against the rear side face of the lower sealing beam, and a filling opening is further formed in the upper sealing beam. Through the arrangement of the first driving device, the lower sealing beam can conveniently swing back and forth by a certain angle so as to meet the requirement that the beam end distance of the support changes along with the change of the height, meanwhile, the lower sealing beam is in lap joint with the lower sealing beam under the action of the gravity of the upper sealing beam, and therefore the gravity of the uppe |
