DETAILED DESCRIPTION

[0019] 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 this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, a concrete mixer with a multi-stage mixing function comprises a shell 1 with a feed port 104 and a discharge port 105, a plurality of groups of first baffles 2 and second baffles 4 are fixed from top to bottom inside the shell 1, so that the inside of the shell 1 is divided into a powder chamber 101, a mixing chamber 102 and a temporary storage chamber 103 from top to bottom, the opposite sides of each group of first baffles 2 and second baffles 4 are rotatably connected with a rotating plate 3 through a bearing, the rotating plate 3 and the opposite sides of the first baffles 2 and the second baffles 4 are sealed by gluing a sealing gasket, the rotating plate 3, the first baffle 2 and the second baffle 4 are vertically provided with a plurality of communicating through holes 301, the annular side surface of the shell 1 is provided with two upper and lower annular holes 106, and the annular side surface of the rotating plate 3 is welded with a protrusion 302 located in the annular hole 106;

[0021] A first stirring component and a second stirring component are respectively disposed in the stirring chamber 102 and the temporary storage chamber 103 .

[0022] During use, the staff pours the concrete powder into the powder chamber 101 through the feed port 104, then the staff grabs the protrusion 302 of the rotating plate located above, and rotates the rotating plate 3 until the protrusion 302 is located at the rightmost end of the annular hole 106. At this time, the first partition plate 2, the second partition plate 4 and the through hole 301 on the rotating plate 3 are connected, and the concrete powder in the powder chamber 101 falls into the stirring chamber 102 through the through hole 301. At the same time, the staff injects water into the stirring chamber 102 and starts the first stirring component to stir the concrete powder. The staff grabs the protrusion 302 of the upper group of rotating plates 3 and rotates them to the leftmost end of the annular hole 106. At this time, the powder chamber 101 located above, the stirring chamber 102 and the through hole 301 on the temporary storage chamber 103 are not connected, and the staff pours the powder into the powder chamber 101 again. This facilitates the next use. When the concrete in the mixing chamber 102 is mixed, the staff grabs the protrusion 302 of the rotating plate 3 located below and drives the rotating plate 3 to rotate, so that the mixing chamber 102 is connected with the temporary storage chamber 103. At this time, the mixed concrete enters the temporary storage chamber 103 through the through hole 301, and the second mixing component is started to continuously mix the mixed concrete to prevent solidification. When the concrete needs to be used, it can be taken from the discharge port 105. The staff rotates the protrusion 302 of the lower set of rotating plates 3 to disconnect the through hole 301, and pours the powder stored in the powder chamber 101 into the mixing chamber 102, and mixes it again, so that the mixing powder temporary storage, concrete mixing and concrete temporary storage of the concrete mixer can be carried out simultaneously, thereby improving the working efficiency of the concrete mixer.

[0023] In this embodiment, the first stirring component includes a rotating shaft 6 rotatably connected to the stirring chamber 102 through a bearing, a plurality of stirring blades 7 welded to the rotating shaft 6, and a first driving motor 5 fixed to the outer side of the shell 1 by bolts. The output shaft of the first driving motor 5 is connected to one end of the rotating shaft 6. When in use, the output shaft of the first driving motor 5 can drive the rotating shaft 6 to rotate. At the same time, the stirring blades 7 stir the concrete in the stirring chamber 102 as the rotating shaft 6 rotates, thereby ensuring the reliability of the concrete mixer when in use.

[0024] In this embodiment, the second stirring assembly includes an anti-mud frame 16 fixed in the temporary storage chamber 103 by bolts, a transmission shaft 9 located in the anti-mud frame 16, a stirring frame 11 rotatably sealed and connected to the lower side of the anti-mud frame 16 through a sealed bearing, and a second drive motor 8 fixed to the outer side of the shell 1 by bolts. One end of the transmission shaft 9 is rotatably connected to the shell 1 through a bearing and is connected to the output shaft of the second drive motor 8. The other end of the transmission shaft 9 and one end of the stirring frame 11 located in the anti-mud frame 16 are both provided with meshing bevel gears. When in use, the output shaft of the second drive motor 8 drives the transmission shaft 9 to rotate. Under the action of the bevel gear 10, the stirring frame 11 stirs the concrete in the temporary storage chamber 103 to prevent the concrete from solidifying, thereby ensuring the quality of the concrete during use.

[0025] In this embodiment, the lower sides of the first drive motor 5 and the second drive motor 8 are both provided with a motor support plate 14 fixed to the outer side of the shell 1 by bolts. When in use, the motor support plate 14 can support the weight of the first drive motor 5 and the second drive motor 8, thereby ensuring the reliability of the first drive motor 5 and the second drive motor 8 when in use.

[0026] In this embodiment, a cover 15 is hinged on the upper side of the feed port 104. When in use, the cover 15 can prevent the powder in the powder cavity 101 from floating out, reducing the waste of powder, and at the same time prevent external rainwater from entering the powder cavity 101, preventing the concrete powder from being contaminated and unusable.

[0027] In this embodiment, the discharge port 105 is provided with an electric valve 12 located outside the shell 1. When in use, the staff can control the opening and closing of the discharge port 105 through the electric valve 12 to prevent concrete from flowing out along the discharge port 105 when not in use, while improving the convenience of the staff in receiving concrete.

[0028] In this embodiment, four supporting legs 13 arranged in a rectangular shape are fixed to the lower end of the outer side surface of the shell 1 by bolts. When in use, the supporting legs 13 can support the concrete mixer, thereby ensuring the reliability of the concrete mixer when in use.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. 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.
