[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0017] Depend on Figures 1 to 4A high-hardness gear-based aluminum alloy powder drying device is provided, comprising a base 1, a workbench 2 above the base 1, a horizontally oriented barrel 3 rotatably connected to the workbench 2, a heating box 4 located below the barrel 3 mounted on the workbench 2, a gear ring 5 fixed to the outside of the barrel 3, a drive shaft 6 rotatably connected to the workbench 2, a first sprocket 7 and a gear 8 coaxially fixed to the drive shaft 6, the gear 8 meshing with the gear ring 5, a coaxially arranged rotating shaft 9 rotatably connected inside the barrel 3, a plurality of stirring rods 10 uniformly fixed to the rotating shaft 9 located inside the barrel 3, a second sprocket 11 coaxially fixed to the rotating shaft 9, the second sprocket 11 located outside the barrel 3, the first sprocket 7 connected to the second sprocket 11 via a chain, an inlet pipe 12 provided on the left side of the barrel 3, and an outlet 13 provided on the right side of the barrel 3;
[0018] The base 1 is fixed with support plates 14 located on the front and rear sides of the workbench 2. The right end of the workbench 2 is hinged to the support plate 14, and the left end of the workbench 2 is hinged to a connecting rod 15. The connecting rod 15 is located below the workbench 2. A slider 16 is slidably connected to the base 1 from left to right. The top end of the slider 16 is hinged to the other end of the connecting rod 15.
[0019] To ensure the stability of the rotation of the barrel 3 and the rotating shaft 9, a first support base 17 and a second support base 18 are fixed on the workbench 2. The left end of the barrel 3 is rotatably connected to the first support base 17, and the right end of the barrel 3 is rotatably connected to the second support base 18. The first support base 17 is rotatably connected to the transmission shaft 6. The feed pipe 12 is fixedly connected to the first support base 17. A first bracket 19 is fixed on the first support base 17. The left end of the rotating shaft 9 is rotatably connected to the first bracket 19. A second bracket 20 is fixed on the second support base 18. The right end of the rotating shaft 9 is rotatably connected to the second bracket 20.
[0020] To ensure the stability of the slider 16 sliding left and right, a hydraulic cylinder 21 is installed on the base 1. The telescopic end of the hydraulic cylinder 21 is fixedly connected to the slider 16. The worktable 2 is fixed with guide rails 22 located on the front and rear sides of the hydraulic cylinder 21. The slider 16 slides along the guide rails 22 in the left and right direction.
[0021] A motor is installed on the workbench 2, and the motor is coaxially and fixedly connected to the transmission shaft 6.
[0022] The heating box 4 is located between the first support 17 and the second support 18, and a heating wire 23 is installed inside the heating box 4.
[0023] In use, the bottom end of the feed pipe 12 is inserted into the barrel 3. Aluminum alloy powder based on the high-hardness gear 8 is transported from the feed pipe 12 into the barrel 3. After feeding is completed, the heating box 4 and the motor are turned on, and the heating wire 23 starts to heat the bottom of the barrel 3. The heat generated is transferred to the aluminum alloy powder in the barrel 3. The motor drives the transmission shaft 6 to rotate, and the transmission shaft 6 drives the first sprocket 7 and the gear 8 to rotate coaxially. The gear 8 drives the gear ring 5 to rotate, and the gear ring 5 drives the barrel 3 to rotate together. In turn, the barrel 3 drives the aluminum alloy powder to rotate. At the same time, the first sprocket 7 drives the second sprocket 11 to rotate via the chain. The second sprocket 11 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the stirring rod 10 to rotate. In turn, the stirring rod 10 can stir the aluminum alloy powder, thereby ensuring that the aluminum alloy powder is heated evenly in the barrel 3.
[0024] Taking the clockwise rotation of the drive shaft 6 as an example, the first sprocket 7 and gear 8 rotate clockwise, gear 8 meshes with the gear ring 5, the gear ring 5 rotates counterclockwise, and thus the barrel 3 also rotates counterclockwise. The first sprocket 7 drives the second sprocket 11 to rotate clockwise via the chain. The second sprocket 11 drives the rotating shaft 9 to rotate clockwise, and the rotating shaft 9 drives the stirring rod 10 to rotate clockwise. The stirring rod 10 rotates in the opposite direction to the barrel 3, which greatly improves the stirring effect of the aluminum alloy powder, ensures uniform heating, improves drying efficiency, and guarantees the drying quality of the product.
[0025] After the aluminum alloy powder is dried, the hydraulic cylinder 21 is activated. The hydraulic cylinder 21 controls the slider 16 to slide to the left along the guide rail 22. The slider 16 drives the left end of the worktable 2 to move upward via the connecting rod 15. The right end of the worktable 2 is hinged to the support plate 14, which effectively controls the rightward tilting of the worktable 2. This helps the dried aluminum alloy powder in the barrel 3 to flow out from the discharge port 13. Under the stirring action of the stirring rod 10, the aluminum alloy powder flows out from the barrel 3. The drying and discharge are convenient, the operation is simple, and the stability is high.
[0026] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
