Steel fiber concrete mixer

Abstract

The invention discloses a steel fiber concrete mixer. The steel fiber concrete mixer includes a mixer body. The upper end of the mixer body is provided with a supporting plate. The bottom part of themixer body is provided with a supporting steel frame. The middle end of the interior of the supporting steel frame is provided with a motor. The left and right ends of a first rotating shaft sleeve are provided with a first fixed rod and a second fixed rod correspondingly. The first fixed rod and the second fixed rod are provided with a first mixer shaft and a second mixer shaft correspondingly. The first mixer shaft and the second mixer shaft are provided with a plurality of first mixing rods and a plurality of second mixing rods correspondingly. When the steel fiber concrete mixer is in use,steel fibers are added into the concrete inside the mixer body separately and evenly through a feed inlet, and the first mixing rod, the second mixing rod, a brushing and scraping rod and a cleaningsteel sheet are driven by a rotating shaft on the motor to evenly mix the steel fibers and the concrete, the steel fibers are made to be evenly distributed in the concrete, agglomeration and uneven mixing of the steel fibers in the concrete are avoided, and the reliability of the steel fiber concrete is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mixers, and in particular relates to a steel fiber concrete mixer. Background technique [0002] Steel fiber reinforced concrete is a new type of multiphase composite material formed by mixing random distributed short steel fibers into ordinary concrete. These randomly distributed steel fibers can effectively prevent the expansion of micro-cracks and the formation of macro-cracks in concrete, significantly improve the tensile, bending, impact and fatigue properties of concrete, and have good ductility. [0003] The mixing effect of the existing steel fiber concrete mixer is poor, and water needs to be added manually during the mixing process. However, the machine is likely to cause the steel fibers to agglomerate in the concrete and the distribution is uneven. In the process of production or experiment, it is often necessary to carry out a screening to remove the agglomerated or agglomerated steel fibers...

Problems solved by technology

[0003] The mixing effect of the existing steel fiber concrete mixer is poor, and water needs to be manually added during the mixing process, but the machine is easy to cause the steel fiber to agglomerate in the concrete and the distribution is uneven

In the process of production or experiment, it is often necessary to carry out a screening to remove the agglomerated or agglomerated steel fibers, which increases the production cost, wastes manpower and material resources, low production efficiency, and the steel fibers are not evenly distributed in the concrete. All indicators of the material are unqualified, which is likely to cause safety hazards
