Concrete stirring machine

Abstract

The invention discloses a concrete stirring machine, which comprises a variable-frequency power supply motor, a rotating shaft, stirring blades, a feeding port, a filter sieve, a stirring barrel, an unloading system, a spiral blade, a transmission shaft, a material conveying barrel, a transmission motor, a bottom turnplate, a turnplate motor, supporting legs, a push plate and a discharging port, wherein the left end of the rotating shaft is in line connection with the variable-frequency power supply motor; the stirring blades are arranged on the rotating shaft in a longitudinally symmetrical mode; the bottom turnplate is fixedly arranged at the lower end of the stirring barrel; a cantilever supporting beam is jogged with the unloading system; the transmission shaft is fixedly connected with the spiral blade; the transmission motor is arranged at the bottom end of the material conveying barrel; the lower part of the bottom turnplat is fixedly connected with the turnplate motor; the supporting legs are fixedly arranged on the left and the right of the bottom turnplate; and the push plate communicates with the internal part of the discharging port. The concrete stirring machine is provided with an automatic conveying belt, and materials are loaded by a spiral conveyer, so cost and labor can be effectively saved; and the concrete stirring machine has high automation degree and a good stirring effect, and effectively increases the concrete stirring speed.

Description

technical field [0001] The invention relates to the technical field of concrete mixing, in particular to a concrete mixer. Background technique [0002] A concrete mixer is a machine that mixes cement, sand and gravel aggregates and water and mixes them into concrete mixtures. It is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device. In order to ensure the mixing quality of concrete, it is required that the concrete mixture be stirred evenly, the mixing time is short, the unloading is fast, the residue is small, the energy consumption is low and the pollution is small. [0003] The traditional mixer has the disadvantages of slow mixing speed, slow mixing speed and low uniformity, which makes the raw materials not meet the requirements after mixing, which brings great inconvenience to the production of enterprises. In the prior art, most concrete mixers use one-time mixing , ...

AI Technical Summary

Problems solved by technology

[0003] The traditional mixer has the disadvantages of slow mixing speed, slow mixing speed and low uniformity, which makes the raw materials not meet the requirements after mixing, which brings great inconvenience to the production of enterprises. In the prior art, most concrete mixers use one-time mixing , uneven mixing

Concrete mixers that use secondary mixing generally use two machines, and the production cost is high. Concrete mixers used in construction sites are bulky, difficult to carry and move, and very inconvenient to use.
