Concrete mixer and ready-mixed concrete producing apparatus using same

Abstract

The invention discloses a concrete mixer capable of improving shearing effect for mulling objects and having high mulling efficiency. The concrete mixer comprises a mixer body accommodating raw material for pre-mixed concrete, a first mulling shaft rotationally arranged on the mixer body and a plurality of stirring paddles, wherein each stirring paddle is formed by an arm body connected to the first mulling shaft and a first plate body arranged on a tip end of the arm body; material can be stirred by the stirring paddle; each first plate body is in a spiral shape, so each first plate body can wind the first mulling shaft and has a concave part in an adjacent part of the plurality of first plate bodies; space near the concave part changes with rotation of the stirring paddles in an irregular way; material flows in an irregular way due to the space changes; and therefore, stirring efficiency and shearing effect can be improved and material can be mulled with high efficiency.

Description

technical field [0001] The present invention relates to a concrete mixer and a ready-mixed concrete manufacturing device equipped with the concrete mixer. Background technique [0002] Ordinary ready-mixed concrete is manufactured by a ready-mixed concrete manufacturing device equipped with a ready-mixed concrete manufacturing device. In the ready-mixed concrete manufacturing apparatus, a concrete mixer is used (Japanese Patent Laid-Open No. 2008-212888). Concrete mixer is used to mix multiple materials such as crushed stone as coarse aggregate, sand as fine aggregate, concrete, water and mixture. [0003] Such as Figure 11 Shown is the internal structure diagram of a common concrete mixer. The ordinary concrete mixer 50 has a mixer body 51 and two kneading shafts 52, 53. A plurality of paddles 54 . These paddles 54 are used for kneading the above-mentioned materials M. Each paddle 54 is composed of an arm body 55 and a plate body 56. Each arm body 55 is connected to ea...

AI Technical Summary

Problems solved by technology

The kneaded material with higher viscosity can only move along the side of the plate body 56, so in the ordinary concrete mixer 50, there is a problem that the shearing effect on the kneaded material with higher viscosity is poor

[0007] Again, when the material M is transported along the sides of these plate bodies 56, as Figure 12 As shown, the material M becomes easy to roll at the bottom of the mixer body 51 and the sides of the plate body 56
