The sieve assembly includes a sieve cylinder, a screen mesh is arranged in the sieve cylinder, a coarse discharge port is fixedly connected to the side of the screen cylinder, a collection box is arranged at the bottom of the screen cylinder, and a fine discharge port is opened on the side of the collection box. The bottom of the collecting box is provided with a vibration motor, the frame is fixedly connected with a mounting frame located below the screen cylinder, and several connecting springs are arranged at intervals along the circumferential direction between the edge of the bottom surface of the screen cylinder and the mounting frame.

The upper end of the material guide ring is connected with the lower end flange of the feeding port, and the lower end of the material guide ring is connected with the upper end flange of the screen cylinder.

Several support rods are fixedly connected in the feeding port at intervals.

Telescopic struts are respectively hinged between two sides of the top of the cover plate and two sides of the lower part of the dust collecting box.

By adopting the above technical scheme, when the utility model is in use, the cover plate is opened, and the bagged powder is poured into the feeding port, and the support rod on the feeding port can support the bagged material, which is convenient for discharging, and on the other hand, makes the powder material Dispersed, the powder is poured into the screen in the sieve cylinder from the feeding port through the material guide ring. Under the action of the vibration motor, vibrating screening is performed. The coarse material is exported from the coarse discharge port, and the fine material is discharged from the fine material. In the process of powder feeding and screening, dust will be generated. At this time, the fan is started. Under the suction of the fan, the dust in the dust collecting box passes through the dust collecting components and is adsorbed by each filter bag to avoid dust. The dust floats into the air. When a large amount of dust accumulates on the filter bag, close the cover, start the drive motor to drive the turret to rotate, and control the fan to blow air into the dust box, so that the powder adsorbed on the filter bag falls down. to collect.
