Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, in particular to a green high-performance concrete mixing mechanism. Background Art

[0002] When mixing concrete, one of the more common construction devices is a concrete mixer, which is a machine that mixes cement, sand and gravel aggregates and water to make a concrete mixture.

[0003] Most concrete mixers use a mixing shaft to stir the materials in the mixing barrel so that cement, sand and gravel aggregates and water are mixed. However, the materials are in a fluid state after mixing and are easily attached to the inner wall of the mixing barrel. The mixing barrel is not completely discharged, resulting in a waste of resources and inconvenient subsequent cleaning. Utility Model Content

[0004] The purpose of the utility model is to propose a green high-performance concrete mixing mechanism in order to solve the above-mentioned technical problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A green high-performance concrete mixing mechanism comprises a mixing barrel and a mixing shaft rotatably arranged on the top surface of the mixing barrel, a motor for driving the mixing shaft to rotate is arranged at the upper end of the mixing barrel, a feeding port is arranged on the side wall of the mixing barrel, a discharge pipe is arranged at the lower end of the mixing barrel, a plurality of mixing rods are arranged locally on the outer surface of the mixing shaft, and a scraping assembly is arranged on the outer surface of the mixing shaft;

[0007] The scraping and sweeping assembly includes a fixing plate and a square frame, wherein the fixing plate is fixedly connected to the outer surface of the stirring shaft, a bolt is penetrated through one side of the upper end of the square frame, a mounting hole matching the bolt is opened on the fixing plate, and a nut is threadedly connected to the upper end of the bolt.

[0008] As a further description of the above technical solution:

[0009] A fixing rod is fixedly arranged inside the square frame, a limiting pin is movably penetrated through the upper end of the fixing plate, and a limiting hole matching with the limiting pin is opened at the upper end of the fixing rod.

[0010] As a further description of the above technical solution:

[0011] The outer surface of the fixing rod is connected to the inner wall of the square frame through a supporting rod, and the number of the supporting rods is multiple.

[0012] As a further description of the above technical solution:

[0013] The end of the fixed plate is rotatably provided with a roller matched with the inner wall of the mixing barrel.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] In the utility model, the square frame is fixed to the lower end of the fixing plate by bolts and nuts. When the outer surface of the square frame contacts the inner wall of the mixing barrel, the fixing plate is driven to rotate as the stirring shaft drives the square frame to revolve along the inner wall of the mixing barrel, thereby achieving the effect of scraping the inner wall of the mixing barrel, avoiding waste caused by residual materials adhering to the inner wall of the mixing barrel, and at the same time, it is convenient for staff to disassemble the square frame for cleaning. When the outer surface of the square frame does not contact the inner wall of the mixing barrel, and cooperates with the fixing rod and the supporting rod, the material can be further stirred as the square frame revolves, thereby improving the stirring efficiency.

[0020] 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 of 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.

[0021] Embodiment 1:

[0022] As shown in 1-3, a green high-performance concrete mixing mechanism comprises a mixing barrel 1 and a mixing shaft 5 rotatably arranged on the top surface of the mixing barrel 1, a motor 3 for driving the mixing shaft 5 to rotate is arranged at the upper end of the mixing barrel 1, a feeding port 2 is opened on the side wall of the mixing barrel 1, a discharge pipe 4 is arranged at the lower end of the mixing barrel 1, a plurality of mixing rods 6 are arranged locally on the outer surface of the mixing shaft 5, and a scraping assembly is arranged on the outer surface of the mixing shaft 5;

[0023] The scraping assembly includes a fixed plate 7 and a square frame 8. The fixed plate 7 is fixedly connected to the outer surface of the stirring shaft 5. A bolt 10 is penetrated on one side of the upper end of the square frame 8. A mounting hole matching the bolt 10 is opened on the fixed plate 7. A nut 11 is threadedly connected to the upper end of the bolt 10. The square frame 8 is fixedly installed at the lower end of the fixed plate 7 by the bolt 10 and the nut 11. During the installation process, the deflection angle of the square frame 8 can be adjusted and controlled. When the outer surface of the square frame 8 contacts the inner wall of the stirring barrel 1, the revolution of the square frame 8 realizes the effect of scraping the inner wall of the stirring barrel 1. When the outer surface of the square frame 8 does not contact the inner wall of the stirring barrel 1, the square frame 8 revolves to achieve the effect of stirring the material, thereby further improving the stirring efficiency.

[0024] Furthermore, a fixing rod 12 is fixed inside the square frame 8, a limit pin 13 is movably penetrated through the upper end of the fixing plate 7, a limit hole matching the limit pin 13 is opened at the upper end of the fixing rod 12, and the limit pin 13 is inserted into the limit hole, thereby ensuring the stability of the installation of the square frame 8 and making it difficult to deflect, thereby avoiding resistance of the square frame 8 during the stirring process, causing the threaded connection to loosen.

[0025] Embodiment 2:

[0026] As shown in 1-3, the outer surface of the fixed rod 12 is connected to the inner wall of the square frame 8 through a support rod 14. There are multiple support rods 14. On the one hand, the strength of the square frame 8 is improved. On the other hand, the square frame 8 is divided into multiple square openings so that the material flows from the middle, that is, the stirring effect during the revolution of the square frame 8 is improved.

[0027] Furthermore, a roller 9 is rotatably provided at the end of the fixing plate 7 and matches with the inner wall of the mixing barrel 1 , thereby effectively ensuring the rotation stability of the mixing shaft 5 and avoiding vibration.
