Reinforced concrete stirrer

Abstract

The invention relates to building machinery and in particular relates to a reinforced concrete stirrer. The concrete stirrer comprises a discharge opening and a conveying pipeline connected with the discharge opening, wherein reinforcing sleeves are respectively arranged outside the discharge opening and the conveying pipeline in a sleeving manner; each reinforcing sleeve is an annular sleeve; a buffer layer is attached to the inner peripheral surface of each reinforcing sleeve; a thermal insulation layer is attached to the peripheral surface; and a scraper which can move in the pipeline is arranged in the conveying pipeline. According to the stirrer disclosed by the invention, the problems that the discharging structure is fragile and easy to break and block and the like in the prior art are solved, and a concrete stirrer of a firm and smooth discharging structure is obtained.

Description

technical field [0001] The invention relates to construction machinery, in particular to a concrete mixer. Background technique [0002] Concrete mixer is a machine that mixes cement, gravel aggregate and water and mixes it into concrete mixture. It mainly consists of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device composition. The unloading mechanism usually includes a discharge port, and for a mixer that directly pours the mixed concrete, it usually also includes a long feeding pipeline. However, the agitator has the following problems when discharging and transporting materials: 1) the high-density concrete suddenly rushes into the weaker discharge port and the material delivery pipeline from the solid mixing drum, which will affect the discharge port and the material delivery channel. The pipes cause great impact and are easily damaged under repeated impacts, especially at the corners, ...

Problems solved by technology

However, the agitator has the following problems when discharging and transporting materials: 1) the high-density concrete suddenly rushes into the weaker discharge port and the material delivery pipeline from the solid mixing drum, which will affect the discharge port and the material delivery channel. The pipes cause great impact and are easily damaged under repeated impacts, especially at the corners, which will affect the use of the mixer; 2) Since the discharge port and the delivery pipe are narrow, the concrete is easy to remain in them If it is not cleared for a long time, it will solidify and block the pipeline, thus affecting the discharge
