The bottom of the U-shaped mounting frame 8 is fixedly connected with a second hydraulic cylinder 12. The telescopic end of the second hydraulic cylinder 12 is fixedly connected with a sealing block 14. A conveying pipe 5 is communicated with the bottom of the placement tank 6, and the bottom of the sealing block 14 is hermetically attached to the top opening of the conveying pipe 5. A temporary storage tank 2 is fixedly connected inside the connecting frame 1. A tapered rod 17 is fixedly connected to the inner wall of the temporary storage tank 2. A double-shaft motor 18 is fixedly connected to the bottom of the tapered rod 17. A stirring shaft 19 is fixedly connected to the lower output shaft of the double-shaft motor 18, and two stirring blades are symmetrically and fixedly connected to the outer wall of the stirring shaft 19. The upper output shaft of the double-shaft motor 18 penetrates through the tapered rod 17 and extends to the top of the tapered rod 17. A scraping blade 16 is fixedly sleeved on the upper output shaft of the tapered rod 17. An opening is formed at the bottom of the temporary storage tank 2, and a sealing disc 3 is hermetically installed in the opening. The temporary storage tank 2 can be installed by welding steel rods outside and then welding them to the connecting frame 1.

[0023] In this embodiment, a plurality of tapered protrusions 21 are arranged in a rectangular array on both sides of the two stirring blades. The outer sides of the stirring blades are closely attached to the inner wall of the temporary storage tank 2, so that the alumina powder and dust on the inner wall of the placement tank 6 can be scraped off for cleaning. Starting the second hydraulic cylinder 12 can drive the sealing block 14 to rise. After the sealing block 14 rises, the opening of the conveying pipe 5 will be opened. Then, the alumina powder will enter the temporary storage tank 2 through the conveying pipe 5, and the alumina powder will slide into the temporary storage tank 2 along the outer wall of the tapered rod 17. When the double-shaft motor 18 is started, the double-shaft motor 18 can drive the stirring shaft 19 and the rotating rod 20 to rotate. The rotation of the stirring shaft 19 will drive a plurality of stirring blades and tapered protrusions 21 to rotate, so as to stir the alumina powder.

[0024] In this embodiment, the top end of the upper output shaft of the double-shaft motor 18 is fixedly connected with a rotating rod 20, and the top end of the rotating rod 20 is fixedly connected with the bottom of the scraping blade 16.

[0025] In this embodiment, a threaded rod 15 is fixedly connected to the top of the sealing disc 3, and the threaded rod 15 is threadedly penetrated through the bottom opening of the temporary storage tank 2.

[0026] In this embodiment, the annular pressing plate 13 surrounds the first hydraulic cylinder 9, and the outer wall of the annular pressing plate 13 is attached to the inner wall of the placement tank 6.

[0027] In this embodiment, two inclined panels 7 are symmetrically and fixedly connected to the top of the placement tank 6, and the inclined panels 7 are located below the U-shaped mounting frame 8.

[0028] In this embodiment, the bottoms of both the placement tank 6 and the temporary storage tank 2 are inclined planes. A receiving box 4 is placed inside the connecting frame 1, and the receiving box 4 is located directly below the temporary storage tank 2.

[0029] The working principle of the present utility model is as follows: Alumina powder can be poured into the placement tank 6. The inclined panels 7 are provided at the top of the placement tank 6, which facilitates the pouring of alumina powder from the side. The alumina powder entering the placement tank 6 can enter the placement tank 6 through the gap between the second hydraulic cylinder 12 and the annular pressing plate 13, and finally can fall on the top of the sealing block 14. Then, the first hydraulic cylinder 9 can be started to drive the lifting plate 11 to descend. After the lifting plate 11 descends, it can drive the two connecting rods 10 to descend. After the two connecting rods 10 descend, they can drive the annular pressing plate 13 to press on the alumina powder for pressure crushing. Moreover, the first hydraulic cylinder 9 can drive the connecting rods 10 and the annular pressing plate 13 to rise and fall repeatedly to completely crush the alumina powder. During the rising process of the annular pressing plate 13, it will contact the inner wall of the placement tank 6 and generate friction, so as to scrape off the alumina powder and dust on the inner wall of the placement tank 6 for cleaning. Starting the second hydraulic cylinder 12 can drive the sealing block 14 to rise. After the sealing block 14 rises, it will open the opening of the conveying pipe 5. Then, the alumina powder will enter the temporary storage tank 2 through the conveying pipe 5, and the alumina powder will slide down along the outer wall of the conical rod 17 into the temporary storage tank 2. When the double-shaft motor 18 is started, the double-shaft motor 18 can drive the stirring shaft 19 and the rotating rod 20 to rotate. The rotation of the stirring shaft 19 will drive a plurality of stirring blades and conical protrusions 21 to rotate, so as to stir the alumina powder. The rotating conical protrusions 21 will collide with the alumina powder, which can cause the alumina powder to be impacted by the conical protrusions 21, so that the alumina powder is crushed. The rotation of the rotating rod 20 can drive the scraping blade 16 to rotate. After the scraping blade 16 rotates, it will generate friction with the inner wall of the conveying pipe 5, so as to scrape off the alumina powder and dust on the inner wall of the conveying pipe 5 for cleaning. Rotating the sealing disk 3 can disconnect the threaded rod 15 from the connection of the temporary storage tank 2. At this time, the bottom opening of the temporary storage tank 2 will be opened, and then the crushed alumina powder can be released into the receiving box 4 for collection.

Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
