The utility model relates to the technical field of dry-mixed
mortar, in particular to a screening device for dry-mixed
mortar, which comprises a box body, a blanking hopper, a support, a storage hopper, a screen drum, a
discharge pipe, a feed hopper, a mounting
pipe and a partition plate, the box body is connected with the support, the partition plate is connected with the inner wall of the box body, the box body is divided into a screening bin and a feeding bin, the screen drum is rotationally connected with the box body and the partition plate and located in the screening bin, and the partition plate is provided with a driving
assembly a which is in transmission connection with the screen drum. The mounting
pipe is connected with the box body, the storage hopper is connected with the upper end of the mounting pipe and is coaxially distributed with the mounting pipe, and the discharging pipe is connected with the lower end of the mounting pipe and is obliquely arranged; the discharging hopper is connected with the lower end of the box body and located below the screening bin, and the inner
diameter value of the discharging hopper is gradually reduced downwards in the height direction of the box body. The screening drum rotates to accelerate screening of
mortar, and the mortar continuously rolls in the screening drum to be screened more thoroughly.
