The brush 37 is arranged in a long strip structure in the front-to-back direction, covering the front-to-back length of the rolling inner liner 32. The bottom end of the brush 37 contacts the top of the rolling inner liner 32. When the driving mechanism 34 drives the rolling inner liner 32 to rotate, the nickel-based alloy powder is screened by the rotation of the rolling inner liner 32. At the same time, the brush 37 on the top of the rolling inner liner 32 cleans the rotating rolling inner liner 32 to prevent the sieve hole from being blocked.

[0023] The upper and lower screening mechanism 4 is arranged below the material discharge port 36, and includes a material blocking plate 41, a screen plate 42, a connecting frame 43, a rotating shaft 44, a support rod 45, a slide 46, an electric telescopic rod 47, an electric control receiving valve 48, a receiving trough 49 and an anti-collision pad 491.

[0024] The sieve plate 42 is connected to the baffle plate 41 in front, back, left and right directions respectively, and the baffle plate 41 forms a square trough body.

The highest point of the material receiving trough 49 is in the same horizontal plane as the central axis of the screening drum 3.
