[0024] Specifically, the motor 4 drives the first bevel gear 5 to rotate, and the first bevel gear 5 drives the second bevel gear 6 and the third bevel gear 8 to rotate inside the support frame 3. The support frame 3 supports the second bevel gear 6 and the third bevel gear 8. The second bevel gear 6 drives the first stirring rod 7 to rotate, and the third bevel gear 8 drives the connecting column 9 to rotate, thereby driving the stirring frame 10 to rotate inside the drying furnace body 2. The stirring frame 10 drives the second stirring rod 11 to rotate. Under the joint action of the first stirring rod 7 and the second stirring rod 11, the metal powder can be efficiently stirred, wherein the stirring frame 10 prevents the metal powder from sticking to the inner wall of the drying furnace body 2.

[0025] Reference Figure 1 The support assembly includes a support rod 12, the lower surface of the support rod 12 is fixedly connected to the upper surface of the base plate 1, and the outer wall of the support rod 12 is fixedly connected to the storage box 13.

[0026] Specifically, the support rod 12 supports and fixes the storage box 13 , and the storage box 13 stores the metal powder.

[0027] Reference Figure 1 and Figure 3 The outer wall of the support rod 12 is fixedly connected to the fixed frame 14; the interior of the fixed frame 14 is fixedly connected to the hydraulic press 15, and the output end of the hydraulic press 15 is fixedly connected to the connecting block 16; the outer wall of the connecting block 16 is fixedly connected to the material transfer cylinder 17, and the interior of the fixed frame 14 is fixedly connected to the support cylinder 18, and the outer wall of the material transfer cylinder 17 is slidably connected to the interior of the support cylinder 18; the inner wall of the support cylinder 18 is provided with a one-way valve 19, and the outer wall of the support cylinder 18 is fixedly connected to the interior of the storage box 13; the outer wall of the material transfer cylinder 17 is slidably connected to the inner wall of the fixed frame 14; the interior of the fixed frame 14 is fixedly connected to the discharge pipe 20.

[0028] Specifically, the hydraulic press 15 pulls the transfer barrel 17 to slide inside the fixed frame 14 through the connecting block 16. At this time, the one-way valve 19 will automatically close, and the one-way valve 19 will open when the transfer barrel 17 is located in the support barrel 18. When the transfer barrel 17 moves above the discharge pipe 20, the metal powder in the storage box 13 can fall into the discharge pipe 20 through the transfer barrel 17, and the discharge pipe 20 plays the role of conveying metal powder.

[0029] Working principle: When the drying furnace needs to be used, the hydraulic press 15 is first started. The hydraulic press 15 pulls the transfer barrel 17 to slide inside the fixed frame 14 through the connecting block 16. At this time, the one-way valve 19 will automatically close. When the transfer barrel 17 moves to the top of the discharge pipe 20, the metal powder in the storage box 13 can pass through the transfer barrel 17 and fall into the discharge pipe 20, and then fall into the drying furnace body 2 through the discharge pipe 20. The first bevel gear 5 is driven to rotate by the motor 4, and the second bevel gear 6 and the third bevel gear 8 are driven to rotate inside the support frame 3 through the first bevel gear 5. The first stirring rod 7 is driven to rotate through the second bevel gear 6, and the connecting column 9 is driven to rotate through the third bevel gear 8, thereby driving the stirring frame 10 to rotate inside the drying furnace body 2. The second stirring rod 11 is driven to rotate by the stirring frame 10. Under the joint action of the first stirring rod 7 and the second stirring rod 11, the metal powder can be efficiently stirred. Under the action of the stirring rack 10, the metal powder is prevented from adhering to the inner wall of the drying furnace body 2. The drying furnace not only achieves the effect of efficiently stirring the metal powder during drying, but the efficient stirring can ensure that the metal powder is evenly heated in the drying furnace, avoiding local overheating or insufficient drying, thereby improving the drying efficiency. At the same time, through stirring, the metal powder can be more fully in contact with the hot air, so that the moisture evaporates more quickly, achieving a better drying effect, and also helps to reduce the adhesion and agglomeration phenomenon during the drying process, and also achieves the effect of quantitative feeding of the metal powder, thereby ensuring that the amount of metal powder dried each time remains consistent, thereby stabilizing the production process and improving production efficiency. By precisely controlling the feeding amount, energy waste caused by excessive or insufficient feeding can be avoided, and the goal of energy saving and emission reduction can be achieved. At the same time, quantitative feeding helps to maintain the consistency of the particle size distribution and dryness of the metal powder, thereby improving the quality and stability of the product.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
