Feed premix elevator beneficial to avoiding leakage

The utility model relates to the technical field of hoisters, in particular to a feed premix hoister beneficial to avoiding leakage, which comprises a hoister body, a baffle is slidably arranged at the top of a feed hopper of the hoister body through driving of an air cylinder, and the baffle can cover the top of an opening of the feed hopper. According to the feeding device, the air cylinder drives the baffle to open the opening of the feeding hopper, premix enters the feeding hopper, the baffle is provided with the pull rope at the same time, the pull rope pulls the material baffle to rotate, then discharging is achieved, and the feeding device is simple in structure, convenient to use and high in practicability. After work is finished, the baffle resets to shield the feeding hopper, dust is prevented from entering, meanwhile, due to the fact that the pull rope on the baffle resets and the material blocking plate resets to shield discharging of the material blocking pipe, the problems that residual premix d
