[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] To solve the technical problem that the stirring blades in the prior art do not have the function of angle adjustment, please refer to Figures 1-4 , the following technical solutions are provided in this embodiment:

[0021] A concrete mixing blade with adjustable angle includes a mixing shaft 2. An adjusting mechanism 5 is installed inside the mixing shaft 2. A fixing block 3 is arranged on the outer side of the mixing shaft 2. The adjusting mechanism 5 passes through the fixing block 3 and is connected to the mixing blade 4. The mixing blades 4 are evenly distributed and are used for mixing concrete. A threaded rod 6 penetrates through the fixing block 3.

[0022] In this embodiment, fixing holes 31 are opened on both sides of the fixing block 3, and the size of the fixing holes 31 matches the size of the threaded rod 6. The threaded rod 6 passes through the fixing holes 31 and is threadedly connected to the adjusting mechanism 5 to fix the mixing blade 4.

[0023] Adopting the above technical solution, by providing the fixing holes 31 for the threaded rod 6 to pass through, the threaded rod 6 can be smoothly threadedly installed in the threaded hole 52, thereby realizing the fixation of the mixing blade 4.

[0024] In this embodiment, the adjusting mechanism 5 includes a rotating shaft 51, a gear 53, and a rack 54. The rotating shaft 51 is fixedly installed on the gear 53, and the rack 54 is engaged with the rack 54. The rotating shaft 51 passes through the mixing shaft 2 and the fixing block 3 and is fixed on the mixing blade 4. Through the arrangement of the gear 53 and the rack 54, the rotating shaft 51 can be driven to rotate, thereby achieving the purpose of adjusting the angle of the mixing blade 4.

[0025] Adopting the above technical solution, the rotating shaft 51 is movably connected to the fixing block 3 and the mixing shaft 2, which facilitates the rotation of the rotating shaft 51, and thus facilitates the adjustment of the angle of the mixing blade 4. By adjusting the inclination angle of the mixing blade 4, not only can the mixing efficiency of the concrete be improved, but also the mixing uniformity can be ensured, thereby improving the quality and performance of the concrete.

[0026] In this embodiment, a threaded hole 52 is provided on the rotating shaft 51. The size of the threaded rod 6 matches that of the threaded hole 52, and the threaded rod 6 is threadedly connected to the threaded hole 52 to fix the rotating shaft 51. After the stirring blade 4 is adjusted to the desired angle, the threaded rod 6 is threadedly connected into the threaded hole 52 to fix the rotating shaft 51.

[0027] With the above technical solution, by providing a plurality of threaded holes 52 on the rotating shaft 51, and the arrangement direction of the threaded holes 52 is set to rotate 20° along the axial direction of the rotating shaft 51 and rotate 70°, it is convenient to adjust the angle of the stirring blade 4 according to the viscosity of the concrete, improving the stirring efficiency and uniformity of the concrete, and thus ensuring that the quality and performance of the concrete meet the requirements.

[0028] In this embodiment, limit bars 541 are provided at both ends of the rack 54. One end of the rack 54 is fixed to the pull rod 542. The provided pull rod 542 is used to pull the rack 54. By pulling the rack 54, the gear 53 is rotated to adjust the angle of the stirring blade 4. At the same time, the provided limit bars 541 limit the rack 54 to prevent the rack 54 from falling off the gear 53.

[0029] With the above technical solution, the limit bars 541 can limit the rack 54, so that the rack 54 will not fall off the gear 53 during movement, affecting the adjustment of the stirring blade 4.

[0030] The stirring shaft 2 is a hollow shaft. A through hole is provided at the top of the stirring shaft 2. The pull rod 542 passes through the through hole and extends to the outside of the stirring shaft 2. When the angle of the stirring blade 4 needs to be adjusted, the gear 53 can be rotated by pulling the pull rod 542. The operation is simple and convenient, and the angles of all the stirring blades 4 on the stirring shaft 2 can be adjusted quickly. The adjusting mechanism 5 is installed inside the stirring shaft 2, and the stirring shaft 2 is installed at the output end of the motor 1.

[0031] With the above technical solution, by providing a through hole in the stirring shaft 2, the movement of the rack 54 can be realized, and then the gear 53 can be driven to rotate, and the operation is simple.

[0032] Working principle: During use, the inclination angle of the stirring blade 4 is adjusted according to the viscosity of the concrete. When stirring ordinary concrete and semi-dry hard concrete with a relatively high plasticity, the stirring blade 4 is vertically installed on the stirring shaft 2. [[ID=ID=19]]

[0033] When the type of the agitated concrete is dry - hard concrete, rotate the threaded rod 6 to separate the threaded rod 6 from the fixed block 3, pull the pull rod 542 to drive the rack 54 to move, and then make the gear 53 rotate, adjust the inclination angle of the stirring blade 4, stop when the stirring blade 4 rotates 20°, thread - install the threaded rod 6 into the threaded hole 52 on the rotating shaft 51 to fix the stirring blade 4, and complete the small - angle inclination of the stirring blade 4.

[0034] When it is necessary to stir concrete with high viscosity and poor fluidity, pull the pull rod 542 to drive the rack 54 to move, and then make the gear 53 rotate, adjust the inclination angle of the stirring blade 4, stop when the stirring blade 4 rotates 70°, thread - install the threaded rod 6 into the threaded hole 52 on the rotating shaft 51 to fix the stirring blade 4, and complete the large - angle inclination of the stirring blade 4.

[0035] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non - exclusive inclusion, so that a process, method, article or device including a series of elements of an angle - adjustable concrete stirring blade not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such a process, method, article or device.

[0036] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
