Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1 and Figure 2 As shown, the material mixer of this utility model embodiment includes a base 1, a material mixing cylinder 2, a support frame 3 and a stirrer.

[0030] The agitator includes a stirring drive mechanism 5, a stirring shaft 6, and multiple stirring rod assemblies 7. The stirring drive mechanism 5 is mounted on a support frame 3 and is driven to the upper end of the stirring shaft 6. The lower end of the stirring shaft 6 extends into the material mixing cylinder 2, and each stirring rod assembly 7 is sequentially mounted on the stirring shaft 6.

[0031] Therefore, the material mixer of this utility model embodiment, by setting a support frame 3 on the outside of the material mixing cylinder 2, can support and install the agitator, thereby enabling the support frame 3 to bear the weight of the agitator, avoiding excessive load of the agitator itself acting on the material mixing cylinder 2 and affecting the material mixing cylinder 2, and ensuring the overall structural stability and reliability of the material mixing cylinder 2.

[0032] Specifically, a feed inlet 201 is provided at the top of the material mixing cylinder 2, and a discharge outlet 202 is provided at the bottom of the material mixing cylinder 2. The material to be mixed is loaded into the material mixing cylinder 2 through the feed inlet 201, and then fully mixed by the stirring action of the agitator. The fully mixed material can be discharged through the discharge outlet 202.

[0033] Specifically, the support frame 3 includes a left support plate 301, a right support plate 302, and a top support plate 303. The left support plate 301 and the right support plate 302 are located on the left and right sides of the material mixing cylinder 2, respectively, and the lower ends of the side support plates 301 and the right support plates 302 are respectively connected and fixed to the base 1. The top support plate 303 is located above the material mixing cylinder 2, and the upper ends of the left support plates 301 and the right support plates 302 are respectively connected and fixed to the top support plate 303.

[0034] Specifically, the stirring drive mechanism 5 uses a stirring motor, which drives the stirring shaft 6 to rotate, thereby achieving full stirring and mixing of the materials in the material mixing cylinder 2 through the stirring rod assembly 7.

[0035] The stirring drive mechanism 5 is fixed to the support top plate 303 by bolts. The support top plate 303 is provided with a through hole for the drive shaft of the stirring drive mechanism 5 to pass through. The drive shaft of the stirring drive mechanism 5 is connected and fixed to the upper end of the stirring shaft 6 through a frustum-shaped adapter.

[0036] Specifically, the stirring shaft 6 is rotatably connected to the top plate and bottom plate of the material mixing cylinder 2 via bearings 8.

[0037] In some embodiments of this utility model, each stirring rod assembly 7 includes a first inclined stirring main rod 701, a second inclined stirring main rod 702, a first inclined stirring auxiliary rod 703, and a second inclined stirring auxiliary rod 704. The first inclined stirring main rod 701 and the second inclined stirring main rod 702 are fixedly mounted on the stirring shaft 6 from top to bottom, and are located on opposite sides of the stirring shaft 6. The first inclined stirring auxiliary rod 703 connects the first inclined stirring main rod 701 and the stirring shaft 6, and the second inclined stirring auxiliary rod 704 connects the second inclined stirring main rod 702 and the stirring shaft 6. Multiple first stirring teeth 705 are vertically connected to the first inclined stirring main rod 701 and the second inclined stirring main rod 702, and each first stirring tooth 705 is inclined upwards. Multiple vertically downward second stirring teeth 706 are provided on the first inclined stirring auxiliary rod 703 and the second inclined stirring auxiliary rod 704. That is, through the above-described structural form of the first inclined stirring main rod 701, the second inclined stirring main rod 702, the first inclined stirring auxiliary rod 703, and the second inclined stirring auxiliary rod 704, not only can the structural stability and reliability of the stirring rod assembly 7 be improved, but the stirring range can also be expanded. By providing upwardly inclined first stirring teeth 705 on the first inclined stirring main rod 701 and the second inclined stirring main rod 702, and by providing downwardly inclined second stirring teeth 706 on the first inclined stirring auxiliary rod 703 and the second inclined stirring auxiliary rod 704, the stirring can be made more uniform and the stirring effect better.

[0038] A first inclined connecting rod 707 is connected between the first inclined stirring main rod 701 and the stirring shaft 6. The first inclined connecting rod 707 is located above the first inclined stirring auxiliary rod 703 and is parallel to the first inclined stirring auxiliary rod 703. A second inclined connecting rod 708 is connected between the second inclined stirring main rod 702 and the stirring shaft 6. The second inclined connecting rod 708 is located above the second inclined stirring auxiliary rod 704 and is parallel to the second inclined stirring auxiliary rod 704. That is, by setting the first inclined connecting rod 707 and the second inclined connecting rod 708, the structural stability and reliability of the stirring rod assembly 7 can be further improved.

[0039] In some embodiments of this utility model, a bottom scraping assembly 9 is further provided inside the material mixing cylinder 2.

The bottom scraping assembly 9 includes a horizontal fixing rod 901, a first horizontal mounting rod 902, and a second horizontal mounting rod 903. The horizontal fixing rod 901 is fixedly installed on the stirring shaft 6 by a first fixing sleeve 904, and the horizontal fixing rod 901 is perpendicular to the stirring shaft 6. The first horizontal mounting rod 902 and the second horizontal mounting rod 903 are both located below the horizontal fixing rod 901. The first horizontal mounting rod 902 and the second horizontal mounting rod 903 are respectively fixedly installed on the stirring shaft 6 by a second fixing sleeve 905. The first horizontal mounting rod 902 and the second horizontal mounting rod 903 are perpendicular to the stirring shaft 6, and the first horizontal mounting rod 902 and the second horizontal mounting rod 903 are perpendicular to each other. A plurality of conical scraping heads 906 are respectively provided at the bottom of the first horizontal mounting rod 902 and the second horizontal mounting rod 903. That is, by installing a bottom scraper assembly 9 at the bottom of the stirring shaft 6, the bottom scraper assembly 9 can be driven to rotate synchronously during the rotation of the stirring shaft 6, thereby effectively scraping the material at the bottom of the material mixing cylinder 2, preventing the material from sticking at the bottom of the material mixing cylinder 2, and further improving the material mixing effect.

[0040] The two ends of the first horizontal mounting rod 902 are connected to the horizontal fixed rod 901 via vertical connecting rods 907, and the two ends of the second horizontal mounting rod 903 are connected to the first fixed sleeve 904 via inclined connecting rods 908, thereby improving the structural stability and reliability of the bottom scraping assembly 9.

[0041] Two first horizontal reinforcing rods 909 are connected to the first end of the first horizontal mounting rod 902, and the two first horizontal reinforcing rods 909 are respectively connected to the two ends of the second horizontal mounting rod 903. Two second horizontal reinforcing rods 910 are connected to the second end of the first horizontal mounting rod 902, and the two second horizontal reinforcing rods 910 are respectively connected to the two ends of the second horizontal mounting rod 903, so that the two first horizontal reinforcing rods 909 and the two second horizontal reinforcing rods 910 are interconnected to form a quadrilateral frame, thereby further improving the overall structural strength and stability of the bottom scraping assembly 9.
