In order to facilitate the feeding of the powder, a feeding pipe 7 of a feeding assembly is provided at the top of the mixing tank body 1, and a feeding pipe 5 (whose cross-sectional shape is generally L-shaped) is connected to the top of the mixing tank body 1, and a bottom plate 2 (only a bottom plate) is provided at the bottom of the horizontal section of the feeding pipe 5. is a partial view), a conveying device 3 for conveniently conveying powder is arranged on the bottom plate 2 (it can be a conveyor belt or other conveying equipment, and it is only a partial diagram. It is a relatively mature technology and will not be described here). In order to reduce the dust generated during the conveying process, a protective card plate 4 with a U-shaped cross-section is arranged at one end of the bottom plate 2 close to the feeding pipe 5, and a protective curtain 10 (the material can be transparent rubber or silicone, etc.) is arranged above the feeding pipe 5. In order to facilitate the feeding operation, a pressure relief hole 6 is installed on the top of the mixing tank body 1.

[0023] See also Figure 1-Figure 5 In order to ensure that the powder does not clump during the conveying process and avoid it remaining on the conveying device 3, the feeding pipe 5 (horizontal section) is provided with a rotating motor 9 of a flipping mechanism, and a rotating shaft 11 is fixedly installed on the output end of the rotating motor 9 through a coupling. The rotating shaft 11 penetrates the feeding pipe 5 and extends to the inside where flipping rods 12 are equidistantly welded, which can facilitate the flipping of the powder to avoid agglomeration. Cleaning brushes 13 are also equidistantly arranged on the side surfaces of the rotating shaft 11, which are staggered with the flipping rods 12. On the one hand, they can assist in flipping and placing agglomerates, and on the other hand, they can also clean the surface of the conveying device 3 to avoid powder remaining on the upper surface.

[0024] See also Figure 1-Figure 5 In order to assist in unloading and avoid residue on the inner wall of the feeding pipe 5, the feeding pipe 5 (vertical section) is provided with an auxiliary unloading mechanism, which can assist in knocking during unloading and avoid agglomeration, so as to facilitate subsequent mixing operations. The auxiliary unloading mechanism includes a driving motor 14 arranged at the top of the stirring tank body 1, and a crankshaft 8 is fixedly installed at the output end of the driving motor 14 through a coupling. The top of the crankshaft 8 is installed with the side wall of the feeding pipe 5 through a mounting seat 15, so that the driving motor 14 can work conveniently and drive the crankshaft 8 to rotate. A collar 16 is sleeved in the middle of the crankshaft 8, and a rotating member 17 (composed of a connecting rod and a rotating block, such as Figure 5 As shown), the rotating member 17 is welded and fixed to the striking block 18 of the striking assembly, a rubber pad 19 is bonded to the end of the striking block 18 to avoid hard contact with the feeding pipe 5, and a guide sleeve 20 is installed on the side wall of the feeding pipe 5 to facilitate the reciprocating vibration and striking of the striking block 18.

[0025] Working principle: When the utility model is in use, the powder to be mixed can be conveyed through the conveying device 3, and the protective card plate 4 cooperates with the protective curtain 10 to reduce the generation of dust during the conveying process. During the conveying, the rotating motor 9 rotates, and the turning rod 12 on the rotating shaft 11 rotates, so that the powder can be turned and stirred, thereby avoiding the occurrence of caking during the conveying process. At the same time, the cleaning bristles 13 rotate accordingly, which can assist in turning, and can also be cleaned to avoid the powder remaining on the conveying device 3. After the powder enters the feeding pipe 5, the driving motor 14 works to rotate the crankshaft 8, and cooperates with the ring 16 and the rotating part 17 to move the knocking block 18 back and forth in the guide sleeve 20, and the feeding pipe 5 can be vibrated and knocked to assist in unloading. The rubber pad 19 can avoid hard contact during the knocking process. Vibration and knocking can prevent the powder from remaining on the inner wall of the feeding pipe 5, and the powder enters the inside of the mixing tank body 1 through the feeding pipe 7, which is convenient for subsequent stirring and mixing operations.
