Evacuation-preventing material guiding special device

The utility model discloses a special device for preventing evacuation and guiding materials, which relates to the technical field of material transfer, and comprises a feed pipe and a discharge pipe, a sealing pipeline is arranged between the feed pipe and the discharge pipe, two ends of the sealing pipeline are respectively communicated with the feed pipe and the discharge pipe, a material tray is arranged in the sealing pipeline in a sliding manner, and the material tray is connected with the discharge pipe. The end, close to the discharging pipe, of the material disc is connected with a lifting column, and the lifting column is slidably connected with the end, away from the feeding pipe, of the sealing pipeline. Therefore, through the movement of the lifting column and the charging tray piston, the pressure intensity in the feeding pipe is quickly reduced, so that materials in a container can conveniently enter the feeding pipe, the material beating and guiding time is shortened, and the problem of idle r
