Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing, in particular to a concrete mixing device for construction engineering. Background Art

[0002] Concrete mixing is a method of mixing cement, lime, water and other materials and stirring them evenly. There are two types of concrete mixing: manual mixing and mechanical mixing. Concrete mixing stations are widely used in my country's industrial, agricultural, transportation, national defense, water conservancy, municipal and other construction projects, and the demand is increasing.

[0003] Concrete mixing is often required during construction projects. Traditional mixing often uses mixers. Small mixers are often used for a small number of construction projects. However, small mixers only use stirring paddles to stir the concrete, which has a poor mixing effect and can easily lead to uneven concrete mixing.

[0004] Therefore we make improvements to this and propose a concrete mixing device for construction engineering construction. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] The utility model discloses a concrete mixing device for construction engineering, comprising a device shell, wherein a take-in and put-out opening is provided at the upper end of the device shell, and an upper mounting plate is hingedly mounted at the take-in and put-out opening, and three supporting legs are fixedly mounted in a triangular array at the lower end of the device shell;

[0007] An annular mounting plate is fixedly mounted on the inner wall of the device housing, and the annular mounting plate is sleeved on the concrete mixing drum. A driving drum is mounted on the upper end of the concrete mixing drum. A double-shaft motor is fixedly mounted on the annular mounting plate and located on the left side of the concrete mixing drum. The upper end of the output shaft of the double-shaft motor is mechanically linked with the driving drum, and the lower end of the output shaft of the double-shaft motor is mechanically linked with the concrete mixing drum.

[0008] A feed port is provided at the upper end of the driving cylinder, and an upper cover plate is installed at the feed port. A stirring shaft is rotatably installed at the middle position of the top end of the driving cylinder. The lower end of the stirring shaft penetrates the concrete mixing drum. A plurality of stirring rods are symmetrically fixedly installed at the left and right ends of the stirring shaft, and the other ends of the plurality of stirring rods on the same side of the stirring shaft are fixedly installed on the scraper. The end of the scraper away from the stirring shaft is in contact with the driving cylinder and the inner wall of the concrete mixing drum.

[0009] The middle part of the lower end of the concrete mixing drum is fixedly installed and connected with a discharge pipe, the lower end of the discharge pipe penetrates the device shell and extends to the bottom of the device shell, and a switch valve is fixedly installed on the discharge pipe.

[0010] As a preferred technical solution of the utility model, the annular mounting plate is rotatably connected to the concrete mixing drum via a bearing.

[0011] As a preferred technical solution of the utility model, the upper end of the concrete mixing drum is communicated with the driving drum, the upper end of the concrete mixing drum is rotatably connected to the lower end of the driving drum, and a sealing rubber ring is provided at the connection between the concrete mixing drum and the driving drum.

[0012] As a preferred technical solution of the utility model, a bearing seat is rotatably mounted on the upper end of the stirring shaft, and the upper end surface of the bearing seat is fixedly connected to the middle position of the top end inside the driving cylinder.

[0015] The beneficial effects of the utility model are:

[0016] 1. This kind of concrete mixing device for construction engineering can drive the driving drum and the concrete mixing drum to rotate by starting the double-shaft motor. The rotating driving drum can stir the concrete through the stirring rod, and the rotating stirring rod can clean the inner wall of the concrete mixing drum through a scraper to avoid the disadvantage that the concrete adheres to the driving drum and the inner wall of the concrete mixing drum is difficult to clean. After the mixing is completed, open the switch valve and the concrete can be discharged through the discharge pipe.

In this type of concrete mixing device used in construction projects, the double-axis motor can drive the concrete mixing drum to rotate through the gear and the second gear, and the double-axis motor can drive the driving drum to rotate through the first sprocket, the second sprocket and the chain.
