When the stirring paddle in the stirring equipment rotates, the materials can be mixed evenly. For this purpose, a chemical stirring paddle is proposed.

[0003] After exploration, for example, a Chinese patent application with application number CN202223573340.2 discloses a chemical stirring paddle. By setting an adjustment component and a locking component, the length of the stirring paddle body can be changed so as to be suitable for the use of barrels with different diameters. At the same time, when changing the length of the stirring paddle body, only the second bolt needs to be turned, which is convenient to use. By setting a rotating component and a locking component, the angle of the stirring paddle body can be changed, thereby changing the rotation radius of the stirring paddle body, which can increase the range of use when using barrels with different diameters.

[0004] However, the above technical solution is that when the motor is connected, two first bolts are inserted together to achieve the limiting of the ring, but the bolts need to be removed with the help of a wrench during installation and removal, which makes the installation and removal not convenient enough.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in the mixing field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 and 2 As shown, the utility model provides a chemical stirring paddle, including a motor rotating shaft 1: a ring 5 is movably provided at the lower end of the motor rotating shaft 1, a threaded shaft 6 is fixedly provided at the upper end of the ring 5, a plurality of slots 7 are provided on the outer surface of the upper end of the ring 5, and four paddles 4 are movably provided on the outer surface of the ring 5;

[0027] In order to reduce the use of tools and make installation and disassembly more convenient, the lower end of the motor rotating shaft 1 is provided with an extrusion fixing device 2 that can achieve convenient docking, which is used to achieve convenient docking between the motor rotating shaft 1 and the threaded shaft 6;

[0028] like Figure 3As shown, the extrusion fixing device 2 includes four protrusions 21 and four limit blocks 22. The four protrusions 21 are respectively fixedly arranged on the outer surface of the lower end of the motor rotating shaft 1. The four limit blocks 22 are respectively fixedly arranged on the upper end of the threaded shaft 6. The limit blocks 22 are inserted between the protrusions 21. Four hinges 23 are respectively fixedly arranged on the upper end of the threaded shaft 6. The movable end of the hinge 23 is fixedly provided with a threaded movable block 24. The upper end of the threaded movable block 24 is fixedly provided with a limit plate 25. The outer surface of the threaded shaft 6 is threadedly connected with a threaded swivel 26. The threaded swivel 26 and the outer surface of the threaded movable block 24 are connected. The surface is threadedly connected. When the lower end of the motor shaft 1 is inserted between the limit blocks 22, the limit blocks 22 are inserted into the gaps between the protrusions 21 to achieve a limiting effect. The threaded swivel 26 rotates upward, so that the threaded movable block 24 is squeezed to concentrate in the middle, thereby wrapping the protrusion 21 to achieve an installation effect, thereby improving the installation efficiency and making the installation more convenient. When disassembly is required, the threaded swivel 26 is held in reverse and the squeezed threaded movable block 24 is loosened according to the rotation direction of the hinge 23, thereby pulling out the motor shaft 1 to achieve the effect of disassembly and replacement.

[0029] Furthermore, in order to be able to adjust the stirring angle, an angle adjustment device 3 is provided on the inner side of the blade 4 for adjusting the angle of the blade 4;

[0030] like Figure 4 As shown, the angle adjustment device 3 includes a connecting rod 31, which is fixedly arranged at one end of the blade 4. A limiting sleeve 32 is fixedly arranged on the outer surface of the ring 5. The connecting rod 31 passes through the inner side of the limiting sleeve 32. A rotating gear 33 is fixedly arranged at one end of the connecting rod 31. A gear ring 34 is movably arranged in the groove inside the ring 5. The gear ring 34 is meshed and connected with the rotating gear 33. A sliding cavity 35 is opened at the upper end of the ring 5. A movable clamp 36 is fixedly arranged at the upper end of the gear ring 34. The movable end of the movable clamp 36 is adapted to the inner side of the clamping groove 7. The gear ring 34 can rotate in the inner groove of the ring 5, thereby driving the rotating gear 33 to rotate. Since the rotating gear 33 and the blade 4 are fixedly connected by the connecting rod 31, when the rotating gear 33 rotates, the blade 4 achieves an effect of angle adjustment. When the adjustment is completed, the movable clamp 36 is clamped in the clamping groove 7 to achieve the effect of rotation restriction, thereby avoiding the problem of driving the gear ring 34 to rotate during stirring.

[0031] The working principle is as follows: when the utility model is in use, the motor rotating shaft 1 and the utility model are connected by squeezing the fixing device 2. After the connection is completed, according to the stirring requirements of the chemical material, the movable clamp 36 is rotated, so that the angle of the blade 4 is adjusted by the angle adjustment device 3. After the adjustment is completed, the movable clamp 36 is clamped in the slot 7 to achieve adjustment and fixation. When disassembly is required, the threaded swivel 26 of the squeezing fixing device 2 is reversed, and the squeezed threaded movable block 24 is loosened according to the rotation direction of the hinge 23, so that the motor rotating shaft 1 is pulled out to achieve the effect of disassembly and replacement.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
