High-efficiency double-horizontal-shaft concrete mixer

Abstract

The invention discloses a high-efficiency double-horizontal-shaft concrete mixer. The high-efficiency double-horizontal-shaft concrete mixer comprises a barrel body, a mixing assembly, two gears, a driving assembly and a discharging assembly, wherein a discharging opening is formed in the bottom of the barrel body; the mixing assembly comprises two mixing shafts which are arranged in parallel, the two ends of each mixing shaft are rotatably connected to the two ends of the barrel body, and seven sets of blade assemblies surround each mixing shaft in the axial direction and are spirally arranged. Seven blades comprise six adjacent forward blades and one reverse blade, the difference between every two adjacent blade assemblies with each mixing shaft as the center is 60 degrees, the rotating direction of the forward blade adjacent to the reverse blade to the farthest forward blade is the same as the rotating direction of the mixing shafts, and the two mixing shafts are arranged in the reverse direction. When the reverse blade in the mixing shaft at the left side is positioned below the horizontal position by 30 degrees, the reverse blade in the mixing shaft at the right side is positioned at the horizontal position. The purpose of efficiently and uniformly mixing concrete can be achieved through the combination of the blades, the oblique cutting angle and the phase angle relation in the mixing assembly.

Description

technical field [0001] The invention relates to a high-efficiency twin-shaft concrete mixer. Background technique [0002] The concrete mixer rotates the stirring shaft to make the concrete inside generate convective movement, diffusion movement, and shearing movement, so as to achieve the macroscopic homogeneity of the mixture, so that it can meet the requirements of use. With the rapid development of the construction industry, the level of infrastructure construction continues to improve, and users have higher and higher requirements for engineering construction quality. Traditional concrete mixers cannot meet the current high-efficiency and energy-saving requirements of the construction industry due to their low mixing efficiency and relatively low mixing quality. It will also cause the consumption of cement per unit volume of concrete to be much higher than that of western developed countries.
