Detailed Implementation

[0062] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0063] Research has revealed that the diameters of raw material tanks from different manufacturers are not the same, and the use of a lifting stirring mechanism alone cannot meet the stirring requirements of raw material tanks of all diameters. Therefore, how to meet the stirring requirements of raw material tanks of different diameters is the problem and objective of this utility model.

[0064] Based on the above research, this disclosure provides a lifting mixer device that facilitates the replacement of raw materials. By designing the mixing blades as foldable, they can rotate upwards to the horizontal under the action of inertia when rotating. Opening the foldable mixing blades can effectively reduce the installation diameter of the mixer blades to adapt to raw material tanks of various diameters, especially suitable for raw material tanks with small-diameter mixing ports.

[0065] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0066] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0067] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0068] Please see Figure 1 and Figure 2 This disclosure provides a lifting mixer device that facilitates the replacement of raw materials, including the following structure.

[0069] The support body 100 is used to install other components of the lifting mixer device for easy replacement of raw materials. To ensure the overall strength of the support body 100, reinforcing ribs can be added as needed, for example, reinforcing ribs can be added to the side wall of the support body 100.

[0070] The stirring mechanism 200 is slidably disposed on the side wall of the support body 100. The stirring mechanism 200 slides vertically on the side wall of the support body 100, so that it can directly extend into the raw material tank 400 for stirring.

[0071] A lifting mechanism 300 is disposed on the top of the support body 100 and is used to drive the stirring mechanism 200 to lift and lower, so as to insert the stirring blades of the stirring mechanism 200 into the tank to be stirred. In this embodiment, the lifting mechanism 300 is an electric hoist; in other embodiments, a cylinder or electric push rod may be used to drive the stirring mechanism 200 to lift and lower.

[0072] When the raw materials in the raw material tank 400 that needs to be stirred are exhausted and need to be added, the empty raw material tank 400 can be moved away by a handcart or forklift and replaced with a new raw material tank 400 to complete the replenishment of raw materials.
