When lifting blade is set, screening effect is good and is avoided that the waste of effective material.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
1 screen drum, 2 isolation covers, 3 discharge buckets, 4 central axises, 5 maces, 6 impact beads in figure.
Specific embodiment
It is right with reference to the accompanying drawings and detailed description in order to which the structure and principle of the utility model is more clearly understood
The utility model is described in detail:
As shown in Figure 1, a kind of rotary screen, screen drum 1, isolation cover 2 and driving device including rack, with sieve pore, machine
The discharge bucket 3 for the feed hopper of material feeding screen drum and access screen drum 1 to discharge is fixedly installed on frame, isolation cover 2 is solid
Fixed screen drum 1 passes through isolation cover 2 and rotates with isolation cover 2 and connects, and 1 inner surface of screen drum is welded with helical blade on the rack, drives
