Description

Technical Field

[0001] This application relates to the technical field of concrete mixing, and particularly to a concrete mixing device. Background Art

[0002] A concrete mixer is a machine that mixes cement, sand and gravel aggregates, water, etc. to make concrete. It mainly consists of a mixing cavity, a motor and a speed reducer. An inlet, a discharge port and a water inlet pipe are provided on the mixing cavity, and a mixing shaft is installed in the mixing cavity. Materials enter the cavity through the inlet, and water is added through the water inlet pipe. Driven by the motor, the mixing shaft rotates to mix the materials and water to make concrete and discharge it from the discharge port.

[0003] In related technologies, such as the Chinese utility model patent with the publication number CN207448799U, a concrete mixer is disclosed, which includes a mixing shaft, a number of mixing blades located in a mixing barrel on the mixing shaft, and a motor for driving the mixing shaft to rotate. The mixing blades include at least two sub-blades distributed along the extension direction of the mixing shaft. One end of the sub-blade is connected to the mixing shaft, and the other end is connected together through a connecting block. An extrusion channel is formed between adjacent sub-blades, and gaps are left between the mixing blades and the inner wall and bottom of the mixing barrel.

[0004] In view of the above related technologies, the following defects are found: Since gaps are left between the mixing blades and the inner wall and bottom of the mixing barrel, when the mixing blades rotate to mix, the materials adhering to the inner wall and at the bottom of the mixing barrel do not directly contact the mixing blades and thus are not easily mixed with the materials in the relatively middle position. Therefore, it is not easy to mix the concrete evenly in a short time. Utility Model Content

Detailed Description of the Embodiment

[0032] The following will Figures 1-4 further describe the present application in detail with reference to the attached drawings.

[0033] The embodiment of the present application discloses a concrete mixing device. Refer to Figure 1 , a concrete mixing device includes a stirring barrel 1 and a stirring assembly 2, and the stirring assembly 2 is arranged inside the stirring barrel 1 to mix the concrete.

[0034] Refer to Figure 1 , a water inlet 11 and a discharge port 12 are opened on the outer side wall of the stirring barrel 1. The water inlet 11 is located on the upper outer side wall of the stirring barrel 1, and the discharge port 12 is located on the outer side wall of the stirring barrel 1 close to the bottom end. In this embodiment, the water inlet 11 and the discharge port 12 are arranged opposite to each other. The side where the water inlet 11 is arranged is the left side wall of the stirring barrel 1, and the side where the discharge port 12 is arranged is the right side wall of the stirring barrel 1.

[0035] Refer to Figure 1 and Figure 2, a bracket 13 is welded at the upper end of the mixing barrel 1. The bracket 13 is arranged above the water inlet 11 and is in a "T" shape. A through hole 131 is provided on the bracket 13, and a funnel 14 is inserted through the through hole 131. The funnel 14 is used for introducing materials, and the materials introduced through the funnel 14 can be pre-mixed with the water entering through the water inlet 11.

[0036] Refer to Figure 1 and Figure 2 , in order to prevent the materials and water from directly entering the mixing barrel 1 for mixing, a baffle 15 is welded below the water inlet 11, so that the materials introduced through the funnel 14 can be first placed on the baffle 15 and pre-mixed with the water entering through the water inlet 11. At the same time, the water entering through the water inlet 11 flushes into the mixing barrel 1 for further mixing.

[0037] Refer to Figure 1 and Figure 3 , the mixing assembly 2 includes a rotating shaft 21, a first stirring shaft 22 and a number of second stirring shafts 23 evenly distributed at equal intervals. The rotating shaft 21 is arranged at the central position of the mixing barrel 1, and the first stirring shaft 22 is arranged at a position above the rotating shaft 21 and is aligned with the position of the water inlet 11. A first stirring blade 221 is integrally formed on the first stirring shaft 22, and the first stirring blade 221 abuts against the upward end of the baffle 15, which is beneficial to shoveling the remaining materials and water on the baffle 15 into the mixing barrel 1 for further mixing.

[0038] Refer to Figure 3 , a number of second stirring shafts 23 evenly distributed at equal intervals are arranged on the outer side wall of the rotating shaft 21 below the first stirring shaft 22. In this embodiment, according to the size of the rotating shaft 21, three second stirring shafts 23 evenly distributed at equal intervals are preferably arranged on the outer side wall of the rotating shaft 21. A second stirring blade 231 is integrally formed on each second stirring shaft 23, and there is a gap between adjacent second stirring blades 231, which is beneficial to mixing the concrete evenly.

[0039] Refer to Figure 1 、Refer to Figure 3 and Figure 4 , a first scraping plate 222 is welded to the end of the second stirring shaft 23 away from the connection with the rotating shaft 21. The first scraping plate 222 abuts against the inner wall of the mixing barrel 1. The first scraping plate 222 is in a long strip shape, so that the first scraping plate 222 can be welded to three second stirring shafts 23 at the same time, and the long strip-shaped first scraping plate 222 makes it difficult for the concrete attached to the inner wall of the mixing barrel 1 to be unevenly mixed. And a first pointed chamfer 2221 is provided at the end of the first scraping plate 222 abutting against the inner wall of the mixing barrel 1, which is beneficial to scraping the concrete attached to the inner wall of the mixing barrel 1 for further mixing.

[0040] Refer toFigure 1 , referring to Figure 3 and Figure 4 , a second scraping plate 232 is integrally formed at the second stirring blade 231 at the bottommost part, and the second scraping plate 232 abuts against the bottom of the stirring barrel 1. A second pointed chamfer 2321 is provided at one end of the second scraping plate 232 where it abuts against the stirring barrel 1, which is beneficial to driving the concrete at the bottommost part of the stirring barrel 1 for stirring.

[0041] The implementation principle of a concrete mixing device according to an embodiment of the present application is as follows: Water is discharged into the stirring barrel 1 through the water inlet 11, and at the same time, materials are introduced into the stirring barrel 1 through the funnel 14. Before the materials enter the stirring barrel 1 for stirring, the materials are first introduced onto the baffle 15 and premixed with the water discharged through the water inlet 11. At the same time, the water discharged through the water inlet 11 flushes into the stirring barrel 1 for further stirring. The first stirring blade 221 shovels the materials and water remaining on the baffle 15 into the stirring barrel 1 for further stirring;

[0042] The concrete that enters the stirring barrel 1 is stirred by three second stirring shafts 23. The concrete remaining on the inner wall of the stirring barrel 1 can be scraped off under the action of the first scraping plate 222 for stirring. The concrete at the bottommost part of the stirring barrel 1 can be driven by the second scraping plate 232 for stirring, which is beneficial to the uniform mixing of the concrete. Stirring the concrete in all directions is beneficial to shortening the time for the concrete to be stirred evenly.

[0043] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
