[0024] Reference Figures 1-3 The device comprises a feeding hopper 1, two fixed platforms 2, at least two impact pieces 3, and an adjusting assembly 4. The feeding hopper 1 can be conical to reduce the possibility of material hiding in dead corners. The two fixed platforms 2 are symmetrically arranged on the two sides of the feeding hopper 1 to support and install other assemblies. The two impact pieces 3 are arranged on the two fixed platforms 2 to impact the feeding hopper 1, thereby loosening the large powder attached to the wall of the feeding hopper 1, and enabling the material in the feeding hopper 1 to overcome the adhesion and friction and smoothly fall. The impact force of the impact piece 3 on the feeding hopper 1 can be reduced, the excessive vibration of the single-sided impact piece 3 can be improved to prevent the feeding hopper 1 from cracking, the vibration range of the impact piece 3 on the feeding hopper can be fully covered, the adhesion of the material on the feeding hopper 1 can be reduced, and the loosening and smooth feeding of the material can be ensured. The adjusting assembly 4 is arranged between the impact piece 3 and the fixed platform 2 to adjust the number and position of the impact piece 3 on the fixed platform 2 to adapt to different feeding requirements.

[0025] In some embodiments, the adjusting assembly 4 comprises at least three threaded hole groups 41, which are equidistantly arranged on the fixed platform 2.
