A speed reducer 1 for driving the mixing frame 5 to rotate is installed above the fixed barrel cover 4. The fixed barrel cover 4 is used to fix the speed reducer 1 and the mixing frame 5. A movable barrel cover 2 is installed on the right side wall of the fixed barrel cover 4 through a hinge. A feeding hopper 3 is installed on the outer wall of the mixing cylinder body 6 at a position near the top on the right side.

[0021] Further, the stirring frame 5 includes a bolt gasket 5-1, a main shaft a 5-2, a spacer sleeve 5-3, an upper skeleton oil seal 5-4, a deep groove ball bearing 5-5, a lower skeleton oil seal 5-6, a main shaft b 5-7, a bearing gland 5-8, an inner spiral 5-9, an outer spiral a 5-10, an upper spiral arm 5-11, an outer spiral b 5-12, and a lower spiral arm 5-13. A bolt gasket 5-1 is padded at the top end of the main shaft a 5-2. Above the bolt gasket 5-1, the main shaft a 5-2 and the bolt gasket 5-1 are connected and installed to the speed reducer 1 through bolts. The spacer sleeve 5-3 is sleeved outside the main shaft a 5-2. The upper skeleton oil seal 5-4 is arranged outside the spacer sleeve 5-3. The bearing gland 5-8 is arranged outside the upper skeleton oil seal 5-4. The deep groove ball bearing 5-5 is installed outside the main shaft a 5-2 and is located below the spacer sleeve 5-3 and the upper skeleton oil seal 5-4. The lower skeleton oil seal 5-6 is installed outside the main shaft a 5-2 and is located below the deep groove ball bearing 5-5. The main shaft b 5-7 is installed at the bottom end of the main shaft a 5-2 through bolts. The upper spiral arm 5-11 is installed on the outer wall of the main shaft b 5-7 and is located at a position near the top end. The lower spiral arm 5-13 is installed on the outer wall of the main shaft b 5-7 and is located at a position near the bottom end. The inner spiral 5-9 is installed on the outer wall of the main shaft b 5-7 and is located between the upper spiral arm 5-11 and the lower spiral arm 5-13. The top end of the outer spiral b 5-12 is installed on the outer wall of the upper spiral arm 5-11 and is located at a position near the outer end. The bottom end of the outer spiral b 5-12 is installed on the outer wall of the lower spiral arm 5-13 and is located at a position near the outer end. The top end of the outer spiral a 5-10 is installed on the outer wall of the upper spiral arm 5-11 and is located at a position near the outer end. The bottom end of the outer spiral a 5-10 is installed on the outer wall of the lower spiral arm 5-13 and is located at a position near the outer end. The stirring frame 5 fixes the entire stirring system through the main shaft a 5-2 and the bolt gasket 5-1, and ensures the concentric and stable rotation of the entire stirring system through the deep groove ball bearing 5-5. The spacer sleeve 5-3 is used to fix the position of the deep groove ball bearing 5-5 to prevent it from shifting upward. The bearing gland 5-8 is also used to fix the deep groove ball bearing 5-5, and at the same time, the upper skeleton oil seal 5-4 is installed above. Under the combined action of the lower skeleton oil seal 5-6, the grease lubrication of the deep groove ball bearing 5-5 is ensured.

[0022] Further, the stirring cylinder 6 is installed obliquely, and the height of the right side of the stirring cylinder 6 is less than the height of the left side, which is convenient for the raw materials inside the stirring cylinder 6 to be discharged through the butterfly valve 7 and the discharge port 8 after being stirred.

[0023] Further, the motor inside the speed reducer 1 is a variable frequency motor, and the speed reducer 1 is controlled by the electric box 9 to adjust the rotation speed of the stirring according to the actual stirring situation.

[0024] Furthermore, the upper spiral arm 5-11 and the lower spiral arm 5-13 are installed in a cross shape. The outer spiral b 5-12 and the outer spiral a 5-10 are symmetrically arranged, and the spiral directions of the outer spiral b 5-12 and the outer spiral a 5-10 are opposite. When the outer spiral b 5-12 rotates, it applies an upward pushing force to the material on its stirring side. When the outer spiral a 5-10 rotates, it applies a downward pressing force to the material on its stirring side, so that the material is offset at multiple angles to achieve the purpose of stirring and mixing.

[0025] Furthermore, the outer spiral a 5-10 is composed of two inner and outer spiral support frames and inclined stirring plates located between the two spiral support frames, and there are gaps between adjacent inclined stirring plates. The material is stirred by slightly pushing and lifting the material upward through the inclined stirring plates.

[0026] Working principle: The stirring frame 5 is driven by the speed reducer 1 to rotate and stir. The electric box 9 adjusts the speed of the speed reducer 1 by adjusting the frequency of the internal frequency converter, so as to realize the stirring of the material by the stirring frame 5 at different speeds, and achieve rapid stirring and uniform mixing. By opening the movable bucket cover 2, the feeding hopper 3 is installed at the feeding port to enlarge the size of the feeding port for convenient feeding. The raw material slides obliquely along the feeding hopper 3 and enters the inside of the stirring cylinder 6 downward after being blocked by the movable bucket cover 2. The stirring cylinder 6 is used to load the stirring material. The stirring frame 5 is driven by the speed reducer 1 to rotate and stir inside the stirring cylinder 6. The speed reducer 1 drives the main shaft a 5-2 to rotate, the main shaft a 5-2 drives the main shaft b 5-7 to rotate, and the main shaft b 5-7 drives the inner spiral 5-9, the outer spiral a 5-10, the upper spiral arm 5-11, the outer spiral b 5-12 and the lower spiral arm 5-13 to rotate. The inner spiral 5-9 rotates to convey the material near the center inside upward, and at the same time makes the raw material at the bottom move inward. The material conveyed to the top then diffuses outward and moves to a position close to the inner wall of the stirring cylinder 6 for stirring. After the stirring is completed, the butterfly valve 7 is opened, and the material is discharged outward along the inside of the butterfly valve 7 and the discharge port 8.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
