Small concrete mixer with screening function

Abstract

The invention discloses a small concrete mixer with a screening function. The small concrete mixer comprises a tank body, stabilizer blades, a feeding opening, a water inlet pipe, stirring rods and adischarging opening; a motor is fixedly connected to the upper surface of the tank body, an upper rotating shaft is fixedly connected to the shaft extending end of the motor, a screening plate is arranged inside the tank body, a worm is fixedly connected to the lower end of the upper rotating shaft, a driven shaft is arranged on the left side of the worm and is sleeved with a worm gear and a cam,and a lower rotating shaft is fixedly connected to the lower end of the worm; the multiple stirring rods are distributed on the lower rotating shaft, a circulation barrel is fixedly connected to the right side wall of the tank body, the screening plate is used for screening concrete aggregate, impurities like dinas in large size cannot pass through the screening plate, the impurities in large sizeare removed, and the concrete grout quality is guaranteed; the screening plate vibrates up and down, concrete raw materials are screened, and the screening efficiency is improved; and the stirring rods are used for stirring concrete, a scraping plate is used for pushing the concrete grout into the circulating barrel through the circulated feeding opening, and the stirring efficiency is improved.

Description

technical field [0001] The invention relates to the field of construction equipment, in particular to a small concrete mixer with screening function. Background technique [0002] Concrete is a powdery hydraulic inorganic gelling material. Add water and stir to form a slurry, which can be hardened in the air or better hardened in water, and can firmly bond sand, stone and other materials together. For a long time, concrete, as an important cementing material, is widely used in Civil engineering, water conservancy, national defense and other projects often need to use concrete mixers in the process of engineering construction. Concrete mixers are machines used to mix concrete, sand and gravel aggregates and water and mix them into concrete mixtures. , feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device, etc. The existing concrete mixers often have low mixing efficiency, and the mixing is not uniform enough to...

Problems solved by technology

Add water and stir to form a slurry, which can be hardened in the air or better hardened in water, and can firmly bond sand, stone and other materials together. For a long time, concrete, as an important cementing material, is widely used in Civil engineering, water conservancy, national defense and other projects often need to use concrete mixers in the process of engineering construction. Concrete mixers are machines used to mix concrete, sand and gravel aggregates and water and mix them into concrete mixtures. , feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device, etc. The existing concrete mixers often have low mixing efficiency, and the mixing is not uniform enough to remove the large volume mixed in the aggregate. Impurities affect the quality of concrete slurry
