Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an automatically cleanable concrete mixing device for building construction. Background Technology

[0002] A concrete mixing plant is a device used to uniformly mix concrete raw materials. Common types include metering mixing plants and high-performance uniform mixing plants. During use, it is necessary to clean it to prevent concrete from sticking to the inside of the plant. However, existing self-cleaning concrete mixing plants can clean and scrape off concrete adhering to the inner wall of the plant through scrapers fixed on the rotating shaft, but they cannot clean concrete adhering to the mixing paddle, resulting in incomplete cleaning. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatically cleanable concrete mixing device for construction. In addition to cleaning and scraping the concrete on the inner wall of the device, it can also clean the mixing paddle, making the cleaning more thorough and effectively improving the cleaning effect.

[0004] To achieve the above-mentioned technical effects, this utility model provides an automatically cleanable concrete mixing device for construction, comprising:

[0005] The mixing tank body is equipped with a stirring motor.

[0006] A rotating shaft is coaxially connected to the output end of the stirring motor and rotatably mounted inside the mixing tank body through the drive of the stirring motor;

[0007] Multiple inner wall cleaning plates are arranged radially and evenly fixed on the rotating shaft. The multiple inner wall cleaning plates can rotate inside the mixing tank body as the rotating shaft rotates to clean the inner wall of the mixing tank body.

[0008] Multiple mixing components are arranged radially and evenly distributed on the surface of the rotating shaft. Each mixing component includes multiple mixing blades spaced apart along the axial direction of the rotating shaft for mixing concrete.

[0009] Multiple cleaning components are provided, each corresponding to one of the multiple stirring components. Each cleaning component includes multiple reciprocating sleeves that are reciprocally slidably mounted on the corresponding stirring blade to clean the stirring blade.

[0010] Preferably, each of the stirring paddles has a plurality of dispersion holes uniformly formed thereon.

[0011] Preferably, a plurality of connecting rods are fixedly installed on the rotating shaft. The plurality of connecting rods are radially distributed around the rotating shaft and are arranged in a one-to-one correspondence with a plurality of inner wall cleaning plates. The first end of each of the plurality of connecting rods is fixedly connected to the rotating shaft, and the second end extends to the inner wall of the mixing tank body and is fixedly connected to the corresponding inner wall cleaning plate.

[0012] Preferably, the multiple reciprocating sleeves within each set of cleaning components are fixedly connected by a connecting plate.

[0013] Preferably, each of the reciprocating sleeves is fixedly connected to a limiting slider, and the corresponding stirring paddle is provided with a limiting groove for the limiting slider to reciprocate on the stirring paddle synchronously when the reciprocating sleeve slides back and forth on the stirring paddle.

[0014] Preferably, a sliding rod is fixedly installed on the reciprocating sleeve located at the top of each cleaning assembly, and a reciprocating groove is correspondingly provided on the top of the mixing tank body for the sliding rod fixedly connected to the reciprocating sleeve to reciprocate when the reciprocating sleeve slides back and forth on the corresponding mixing paddle.

[0015] Preferably, the reciprocating groove includes a plurality of wavy groove segments radially distributed around the rotating shaft and connected end to end. Each of the wavy groove segments has a proximal end relatively close to the rotating shaft and a distal end relatively far from the rotating shaft.

[0016] The technical effects achieved by this utility model due to the adoption of the above technical solution are as follows:

[0017] The rotating shaft rotates through the sliding rod, reciprocating groove, and reciprocating sleeve, and drives the reciprocating sleeve and sliding rod to rotate synchronously relative to the reciprocating groove through the stirring paddle. During the process, the top of the sliding rod is pushed by the wall of the reciprocating groove and slides along the reciprocating groove, so as to drive the reciprocating sleeve located on the same side to move back and forth on the stirring paddle, thereby cleaning the stirring paddle, making the cleaning more thorough and effectively improving the cleaning effect.

Cleaning of the inner wall of the main body 1; multiple mixing components are arranged radially and evenly distributed on the surface of the rotating shaft 4. Each mixing component includes multiple mixing blades 5 spaced apart along the axial direction of the rotating shaft 4 for mixing concrete; multiple cleaning components are arranged one-to-one with the multiple mixing components. Each cleaning component includes multiple reciprocating sleeves 6 that are arranged one-to-one with the multiple mixing blades 5 in each mixing component and can be reciprocally slidably fitted onto the corresponding mixing blades 5 to achieve cleaning of the mixing blades 5. The rotating shaft 4 is driven to rotate by the mixing motor, which drives the mixing blades 5 to rotate, thereby realizing the mixing of concrete.

[0024] Furthermore, in this embodiment, each mixing paddle 5 is uniformly provided with multiple dispersion holes 51. These uniformly arranged dispersion holes 51 allow for more even dispersion of the concrete. After mixing, the outlet at the bottom of the mixing tank body 1 is opened for material discharge. Preferably, in this embodiment, multiple connecting rods 10 are fixedly installed on the rotating shaft 4. These connecting rods 10 are radially distributed around the rotating shaft 4 and correspond one-to-one with multiple inner wall cleaning plates 9. The first end of each connecting rod 10 is fixedly connected to the rotating shaft 4, and the second end extends to the inner wall of the mixing tank body 1 and is fixedly connected to the corresponding inner wall cleaning plate 9. It should be noted that the rotating shaft 4 is driven to rotate by the mixing motor, which in turn drives the multiple inner wall cleaning plates 9 to rotate, thereby cleaning and scraping away the concrete adhering to the inner wall of the mixing tank body 1.

[0025] Furthermore, in this embodiment, multiple reciprocating sleeves 6 within each cleaning assembly are fixedly connected by connecting plates 7.

It should be noted that in this embodiment, the reciprocating groove 6 includes multiple wavy groove segments arranged radially around the rotating shaft 4 and connected end to end. Each wavy groove segment has a proximal end relatively close to the rotating shaft 4 and a distal end relatively far from the rotating shaft 4. The sliding rod 8 is slidably disposed in the reciprocating groove 3. When the sliding rod 8 rotates relative to the reciprocating groove 3, the groove wall of the reciprocating groove 3 further generates a thrust on the sliding rod 8, thereby pushing the sliding rod 11 to move back and forth between the multiple proximal ends and multiple distal ends of the reciprocating groove 3. This drives the reciprocating sleeve 6 located on the same side of the rotating shaft 4 to slide back and forth on the stirring paddle 5 along with the sliding rod 8, thereby achieving cleaning of the stirring paddle 5, making the cleaning more thorough, improving the cleaning effect, and eliminating the need for an additional drive source to drive the reciprocating sleeve to slide back and forth, further saving manufacturing costs.
