Detailed Description

In order to make the utility model discloses a more clear that technical scheme and advantage can express will combine below the utility model discloses a drawing, it is right the utility model discloses carry out more clear complete description:

install at the cylinder tip cylinder end cover (1), utilize bolted connection on axle head retaining ring (2), what of gap (4) quantity, can come according to actual in service behavior and decide for gap (4) that are used for screening the object that drum sieve cylinder (5) surface set up, the utility model discloses in set up eight gaps (4) that are used for screening the object, gap (4) quantity is set for more, and the efficiency of screening the object will be faster, and gap (4) quantity is set for less, and the efficiency of screening the object will be slower. The opening size of the gap (4) can be detected by a sensing device, and the rotating angle of the blade (3) is adjusted to adjust the size of the gap.

The surface of the cylindrical roller (5) is provided with eight blades (3) used for screening objects, as shown in fig. 3, the shape of each blade (3) is arc-shaped, the size of the arc radius of each blade (3) is the same as that of the section radius of the cylindrical roller (5), and the blades (3) and the cylindrical roller (5) can be in seamless fit when the blades (3) are closed, a plane (11) is arranged on each blade (3), and the blades (3) are prevented from interfering with the cylindrical roller (5) in the opening process of the blades (3).
