[0003] For sensitive material, usually less blade is used to reduce shear and prevent biological active ingredients from being damaged, and for solid material, more blades are needed to enhance shear force, but existing agitator is usually fixed and integrated, connected with motor reducer or coupling by bolt or welding, when different number of blades needs to be replaced according to actual situation, disassembly is relatively cumbersome, and the cost of spare agitator is also high. Therefore, an arc blade spiral agitator is needed, which can directly install or dismount blade while ensuring stirring efficiency, reduce cost, and facilitate replacement of damaged blade. SUMMARY

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] An arc blade spiral agitator includes a stirring rod and a plurality of blades.

[0007] A base is used to mount the blades on the outer wall of the base, the base is fixedly sleeved on the outer wall of the stirring rod, one end of each of the plurality of blades is fixedly provided with a mounting seat, and the mounting seat is sleeved on the top of the outer wall of the base.

[0008] A fixing mechanism is used to fix the base and the mounting seat, the fixing mechanism is arranged on the outer wall of the stirring rod, the fixing mechanism includes a plurality of insertion plates, an inner cavity is formed in the mounting seat, each of the plurality of insertion plates is slidingly arranged in the inner cavity, an insertion slot is formed in the outer wall of the stirring rod, one end of the insertion plate slidingly penetrates the mounting seat and cooperates with the adjacent insertion slot.

[0009] In one possible design, the fixing mechanism further includes multiple movable bars, one end of which slides through into the interior of multiple cavities. The top of the insert plate is provided with an oblique sliding hole, and one end of each movable bar is fixedly provided with a movable rod, with one end of the movable rod located inside the oblique sliding hole.

[0010] In one possible design, a limiting shaft is fixedly installed inside the cavity, and the insert plate is slidably sleeved on the outer wall of the limiting shaft. A compression spring is sleeved on the outer wall of the limiting shaft, and the two ends of the compression spring are respectively fixedly installed on one side of the inner wall of the cavity and one side of the insert plate.

At this point, the mounting base with the fixed blades can be hung on the outer wall of the top of the base and can rotate along the center of the base for arbitrary positioning. The insert plate is then reset by a compression spring, inserting one end into the slot to initially fix the blades.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figure 1 A stirrer includes: a stirring rod 1, blades 3, a base 4, and a fixing mechanism. The stirring rod 1 can be connected to the reducer or coupling of a motor by existing bolts or welding. The base 4 is fixedly sleeved on the outer wall of the stirring rod 1 and is used to install the blades 3.

[0026] ReferenceFigures 2-3 One end of the blade 3 is connected to the base 4 via the mounting seat 9. The mounting seat 9 is fitted onto the top of the outer wall of the base 4 and is fixed to the base 4 by a fixing mechanism.

[0027] The fixing mechanism is located on the outer wall of the stirring rod 1, specifically including multiple insert plates 19. The mounting base 9 has an inner cavity 16, and the insert plates 19 are slidably disposed inside the inner cavity 16. The outer wall of the stirring rod 1 has a slot 7, and one end of the insert plate 19 slides through the mounting base 9 and cooperates with the adjacent slot 7, thereby initially fixing the mounting base 9 to the base 4.

[0028] To control the sliding of the insert plate 19, the fixing mechanism also includes multiple moving strips 12. One end of each moving strip 12 slides through the interior of the inner cavity 16. The top of the insert plate 19 has an oblique sliding hole 18, and a moving rod 14 is fixedly mounted on one end of each moving strip 12. One end of the moving rod 14 is located inside the oblique sliding hole 18. When the moving strip 12 moves, the moving rod 14 pushes the insert plate 19 to slide along the limiting shaft 17 under the action of the oblique sliding hole 18, thereby realizing the extension or retraction of the insert plate 19.

[0029] To maintain the stability of the insert plate 19, a limiting shaft 17 is fixedly installed inside the inner cavity 16, and the insert plate 19 is slidably sleeved on the outer wall of the limiting shaft 17. A compression spring 15 is sleeved on the outer wall of the limiting shaft 17, with its two ends fixedly installed on one side of the inner wall of the inner cavity 16 and one side of the insert plate 19, respectively. The compression spring 15 provides elastic force to the insert plate 19, keeping it in an extended state when no external force is applied.

[0030] The fixing mechanism also includes an upper cover plate 2, which is slidably sleeved on the outer wall of the stirring rod 1. A plurality of fixing rods 11 are fixedly provided at the bottom of the upper cover plate 2, and a fixing groove 10 is provided at the top of the mounting base 9. The fixing rods 11 cooperate with the fixing groove 10 to further fix the mounting base 9.

[0031] To secure the upper cover plate 2 to the base 4, a limiting rod 6 is fixedly installed at the bottom of the upper cover plate 2, with the bottom end of the limiting rod 6 sliding through to the base 4. A threaded rod 5 is provided at the bottom of the upper cover plate 2, with the top end of the threaded rod 5 rotating through to the top of the upper cover plate 2. A threaded groove 8 is provided at the top of the base 4, and the bottom end of the threaded rod 5 extends into the threaded groove 8. The upper cover plate 2 and the base 4 are secured by rotating the threaded rod 5.

[0032] To facilitate the movement of the pressing moving strip 12, a side groove 13 is provided on one side of the mounting base 9, and one end of the moving strip 12 is located inside the side groove 13.

[0033] Specifically, by pressing the moving bar 12, the moving bar 12 drives the moving rod 14 to move. The moving rod 14 will displace inside the oblique sliding hole 18, thereby pushing the insert plate 19 to move, causing the insert plate 19 to retract into the inner cavity 16. At this time, the mounting base 9 with the fixed blade 3 can be hung on the outer wall of the top of the base 4, and can be rotated along the center of the base 4 for arbitrary position adjustment. Then, the insert plate 19 will be reset by the compression spring 15, so that one end is inserted into the slot 7, thereby initially fixing the blade 3. Then, the threaded rod 5 will be rotated, and the threaded rod 5 will spiral downward, thereby driving the upper cover plate 2 to move downward. The fixing rod 11 at the bottom of the upper cover plate 2 will be inserted into the fixing groove 10 to fix the mounting base 9, and the bottom surface of the upper cover plate 2 will also press against the top surface of the mounting base 9, further fixing the blade 3, thereby ensuring stability. This allows for direct adjustment of the number of blades 3 according to actual needs, and also facilitates timely replacement when blades are damaged.

[0034] This application can be used in the field of mixing equipment, or in other fields applicable to this application.

The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
