[0032] Embodiment 2

[0033] As Figures 1 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes a stirring component 5;

[0034] In this embodiment, the stirring component 5 includes an adjusting shaft rod 10, an assembly seat 11, a transmission shaft rod 12, a hydraulic rod 13 and a guiding frame 14. One end of the assembly frame 4 is rotatably connected to the adjusting shaft rod 10. The end of the adjusting shaft rod 10 located inside the assembly frame 4 is fixedly connected to the assembly seat 11. One end of the assembly seat 11 is vertically rotatably connected to the transmission shaft rod 12. A hydraulic rod 13 is vertically fixedly connected to the middle of the assembly seat 11. The output end of the hydraulic rod 13 is fixedly connected to the guiding frame 14. One end of the guiding frame 14 is rotatably connected to a stirring roller 15, and the stirring roller 15 is also slidably connected to the outside of the transmission shaft rod 12;

[0035] Among them, a limiting strip is fixedly connected to the outside of the transmission shaft rod 12, a limiting groove is opened in the middle of the stirring roller 15, and the limiting strip is also slidably connected to the inside of the limiting groove. With the structural cooperation of the limiting strip and the limiting groove, during the rotation of the transmission shaft rod 12, the limiting strip can drive the stirring roller 15 to rotate accordingly, and when the stirring roller 15 slides, the displacement of the stirring roller 15 can be effectively guided by the limiting strip;

[0036] Preferably, a plurality of stirring fan blades are fixedly connected to the outside of the stirring roller 15, and a plurality of weight-reducing through grooves are opened in the stirring fan blades. With the arrangement of the stirring fan blades, the contact range between the stirring roller 15 and the metal powder can be greatly increased, thereby ensuring the application effect of the stirring roller 15;

[0037] The stirring component 5 further includes an eccentric drive plate 16, an extension base 17, a hydraulic cylinder 18, a drive motor 19, and a drive bevel gear 20. One end of the adjusting shaft rod 10 located outside the assembly frame 4 is fixedly connected to the eccentric drive plate 16. One end of the assembly frame 4 near the eccentric drive plate 16 is fixedly connected to the extension base 17. The top end of the extension base 17 is rotatably connected to the hydraulic cylinder 18, and the output end of the hydraulic cylinder 18 is rotatably connected to one end of the eccentric drive plate 16. One end of the assembly frame 4 away from the adjusting shaft rod 10 is fixedly connected to the drive motor 19. The output end of the drive motor 19 is fixedly connected to the drive bevel gear 20. The top end of the transmission shaft rod 12 is fixedly connected to a transmission bevel gear 21, and the transmission bevel gear 21 is meshed with the drive bevel gear 20;

[0038] Here, one end of the eccentric drive plate 16 away from the adjusting shaft rod 10 is fixedly connected to a linkage rod. The output end of the hydraulic cylinder 18 is fixedly connected to a linkage ring, and the output end of the hydraulic cylinder 18 is connected to the outside of the linkage rod through the linkage ring. With the structural cooperation of the linkage ring and the linkage rod, an effective connection can be achieved between the hydraulic cylinder 18 and the eccentric drive plate 16, and the hydraulic cylinder 18 and the eccentric drive plate 16 can be prevented from disengaging;

[0039] Among them, one end of the assembly frame 4 near the drive motor 19 is fixedly connected to a protective housing, and the drive motor 19 is located inside the protective housing. With the setting of the protective housing, effective protection can be provided for the drive motor 19, and the protective housing and the assembly frame 4 can be connected by screws;

[0040] A specific application of the above two embodiments is as follows: Pour the required metal powder into the storage tank 2 for concentration. Then start the drive motor 19 to cause the drive bevel gear 20 to drive the transmission bevel gear 21, thereby driving the transmission shaft rod 12 to rotate continuously. And in cooperation with the connection between the transmission shaft rod 12 and the stirring roller 15, the stirring roller 15 rotates following the transmission shaft rod 12 and stirs the metal powder inside the storage tank 2. Moreover, the hydraulic rod 13 can be started to push the guiding frame 14 to adjust vertically, so that the stirring roller 15 can slide on the outside of the transmission shaft rod 12 and rotate following the transmission shaft rod 12 at the same time, thereby changing the stirring height of the stirring roller 15;

[0041] The hydraulic cylinder 18 can be activated to push the eccentric drive plate 16. Since the eccentric drive plate 16 is supported by the adjusting shaft rod 10, the assembly seat 11 can be driven to rotate by the adjusting shaft rod 10, causing the transmission shaft rod 12 and the stirring roller 15 to tilt. During the adjustment process, the transmission bevel gear 21 travels at the driving bevel gear 20. Therefore, the transmission bevel gear 21 will not disengage from the driving bevel gear 20. The guiding motor 6 can be activated, and with the setting of the linkage belt 9, the power of the guiding motor 6 can be transmitted to the guiding shaft rod 3, prompting the assembly frame 4 to rotate and changing the working position of the stirring roller 15. Thus, it is possible to fully stir the metal powder at various places in the storage tank 2 without occupying too much space inside the storage tank 2, reducing the working blind area of the stirring roller 15 and ensuring the mixing effect between the metal powders.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
