Stirrer

Abstract

The invention relates to a stirrer. The stirrer comprises a supporting rack and a motor, the upper portion, the middle portion and the lower portion of the supporting rack are respectively correspondingly provided with a first-stage stirring device, a second-stage stirring device and a third-stage stirring device, the first-stage stirring device is used for coarse stirring of a concrete raw material, the second-stage stirring device is used for semi-fine stirring of the concrete raw material, and the third-stage stirring device is used for fine stirring of the concrete raw material; and the motor is positioned above the supporting rack. The stirrer adopts a multi-stage stirring mode comprising the coarse stirring, the semi-fine stirring and the fine stirring which do not interfere with each other, realizes the full stirring of the concrete raw material, allows the raw material to be added in the stirring process to realize continuous stirring of the concrete raw material, and provides guarantee for the continuous supply of concrete; and the stirrer uses the three-stage stirring devices to make the concrete raw material have convective flow, ensures the uniform mixing of the concrete raw material, and improves the stirring quality of the concrete.

Description

technical field [0001] The invention relates to the technical field of stirring machinery, in particular to a stirring machine. Background technique [0002] As we all know, a concrete mixer is a machine that mixes cement, sand and gravel aggregates and water and mixes them into concrete mixtures. and so on. Because the traditional mixing method is relatively simple and the mixing is not thorough enough, it is necessary to mix the same concrete raw material multiple times, which takes a long time and has low mixing efficiency, which increases the processing cost, and is limited by the volume of the mixing container. The amount of concrete is limited; there is also a one-way spiral mixing method, which speeds up the rhythm of mixing. However, because the one-way spiral can only promote the movement of raw materials in one direction in the container, it is easy to cause raw materials to deposit on one side, which is not conducive to materials. Due to the limitation of the vo...
