Recycled concrete mixer capable of improving mixing uniformity

Abstract

The invention relates to the technical field of a recycled concrete production device, in particular to a recycled concrete mixer capable of improving mixing uniformity. The recycled concrete mixer capable of improving mixing uniformity comprises a mixing drum, a mixing shaft, and multiple groups of mixing paddles connected to the side wall of the mixing shaft, wherein a supporting plate is arranged above the mixing drum; the upper end and lower end of the mixing shaft are respectively and rotatably connected to the supporting plate and the bottom wall of the mixing drum; each group of mixingpaddle comprises a plurality of mixing rods horizontally arranged, and multiple groups of paddles fixedly connected to the mixing rods; the ends of the mixing rods are rotatably connected to the mixing shaft; a first driving mechanism is arranged on the mixing drum; the mixing drum is also internally provided with a turning mechanism for turning concrete; the first driving mechanism is used for driving the mixing rods and the paddles to rotate, so that concrete aggregate deposited on the bottom of the mixing drum can be upwards turned; and the turning mechanism can turn the concrete to cause the concrete to be mixed more uniform, and can effectively improve the working efficiency of the mixer.

Description

technical field [0001] The invention relates to the technical field of recycled concrete production devices, in particular to a recycled concrete mixer that improves mixing uniformity. Background technique [0002] Recycled concrete means that waste concrete blocks are crushed, cleaned and graded, mixed with gradation in a certain proportion, partially or completely replaced by natural aggregates (mainly coarse aggregates) such as sand and gravel, and then added with cement, water, etc. new concrete. Recycled concrete can have the following situations according to the combination of aggregates: all aggregates are recycled aggregates; coarse aggregates are recycled aggregates, fine aggregates are natural sand; coarse aggregates are natural gravel or pebbles, fine aggregates The raw materials are recycled aggregates; recycled aggregates replace part of the coarse or fine aggregates. [0003] When using recycled concrete, it is necessary to fully mix the recycled concrete so ...

AI Technical Summary

Problems solved by technology

[0006] The above scheme has the following defects: due to the heavy weight of the concrete aggregate, when the concrete is mixed, the concrete aggregate tends to deposit to the lower part of the mixing drum, and the stirring rod can only stir the concrete in the horizontal direction, and cannot Turn the concrete in the vertical direction, so a part of the concrete aggregate is easy to deposit at the bottom of the mixing drum, thus affecting the uniformity of concrete mixing
