TECHNICAL FIELD
[0001] The present application relates to the technical field of concrete production equipment, and particularly relates to a stirring device for concrete production. BACKGROUND
[0002] The concrete stirring device is an important equipment in modern building construction and is widely used in various civil engineering projects. The traditional concrete stirring tank is mainly divided into vertical and horizontal types. The stirring tanks of the two types are widely used due to their simple structure and convenient operation. However, with the continuous expansion of the scale of building engineering and the improvement of technical requirements, the existing concrete stirring device has been difficult to meet the needs of high-quality concrete production.
[0003] In order to ensure the uniformity and stability of the concrete mixture, the common solutions on the market mainly include: 1) increasing the number of stirring blades and changing the shape of the blades to improve the stirring efficiency; 2) adopting a multi-stage stirring process, that is, the raw materials are preliminarily mixed and then finely stirred; and 3) adjusting the stirring speed and time to adapt to different types and proportions of concrete raw materials. Although these methods can improve the stirring effect of the concrete to some extent, there are still some deficiencies.
[0004] The concrete stirring device in the prior art generally has the problem of uneven stirring, especially the stirring amplitude of the concrete near the main shaft of the stirring blade is low, which causes the concrete in this area to not be fully mixed, and in severe cases, the concrete may even solidify on the main shaft, which seriously affects the quality and production efficiency of the concrete. SUMMARY
[0005] In order to solve the above problems, the present application provides a stirring device for concrete production.
[0006] The stirring device for concrete production comprises a base, a swinging mechanism and a stirring mechanism. The top of the base is provided with a lifting plate, the end of the lifting plate is hinged to the end of the base, the top of the lifting plate is fixedly provided with a stirring cylinder, the swinging mechanism comprises a limiting frame fixed to the top of the base, the swinging mechanism further comprises a slide rail arranged in parallel to the top end of the base, and the slide rail is arranged in the limiting frame, a moving seat is slidably installed on the slide rail, mounting supports are protrudingly arranged on the top of the moving seat, the mounting supports are at least three, the mounting supports are perpendicular to the moving seat, the swinging mechanism further comprises a rotating assembly, the rotating assembly comprises a main shaft, at least two U-shaped shafts and at least two push shafts, the mounting supports are provided with rotating holes for the rotation of the main shaft and the U-shaped shafts, the U-shaped shafts are connected to the two ends of the main shaft, and the U-shaped shafts and the main shaft rotate coaxially, the push shafts are installed in one-to-one correspondence with the U-shaped shafts, and the ends of the push shafts away from the U-shaped shafts are hinged to the lifting plate.
[0007] By adopting the above technical solution, this concrete production mixing device can achieve multi-angle mixing effects, effectively avoiding the uneven mixing problems existing in traditional vertical or horizontal mixing tanks. The mixing drum can tilt with the swing of the lifting plate, allowing the concrete to be mixed at different heights and angles during the mixing process, thereby improving the mixing uniformity. The matching design of the main shaft and U-shaped shaft, as well as the action of the push shaft, enable the mixing drum to perform complex three-dimensional movements, further enhancing the mixing efficiency.

[0013] By adopting the above technical solutions, a more efficient concrete mixing process can be achieved. Specifically, the two opposing mixing shafts ensure uniform mixing of concrete throughout the mixing drum, avoiding the problem of insufficient mixing of concrete near the shaft in traditional mixing equipment.

[0016] Preferably, the stirring blades are spirally wound, and the middle part of the stirring blades is bent towards the direction away from the rotation axis of the stirring drum.
[0017] By adopting the above technical scheme, the spiral winding design of the stirring blades can continuously push the concrete during stirring, thereby improving the stirring efficiency and uniformity. The bending of the middle part of the stirring blades towards the direction away from the rotation axis of the stirring drum can effectively increase the stirring range, avoid insufficient stirring of the concrete near the central area, and further improve the mixing effect.
[0018] Preferably, the two ends of the stirring blades are bent towards the direction of the rotation axis of the stirring drum, and each end of the stirring blades is fixedly provided with an insertion seat, and the insertion seat is provided with at least two insertion holes for inserting the stirring blades along the circumference of the insertion seat.
[0019] By adopting the above technical scheme, the stirring blades can be more closely attached to the inner wall of the stirring drum, effectively preventing the concrete from sticking or stagnating during stirring, and improving the stirring efficiency and quality. The design of the insertion seat facilitates the replacement and maintenance of the stirring blades, prolonging the service life of the equipment.
[0020] Preferably, the stirring drum is provided as an oval drum with a bulge in the middle, and a plurality of barrier strips are arranged on the inner surface of the stirring drum along the length direction of the stirring drum and annularly distributed along the rotation axis of the stirring drum.
[0021] By adopting the above technical scheme, the oval drum with a bulge in the middle can increase the effective volume of the stirring drum and make the concrete more uniformly distributed during stirring; the barrier strips are arranged along the length direction of the stirring drum and annularly distributed along the rotation axis, which can effectively prevent the concrete from forming a vortex effect during stirring, thereby improving the mixing efficiency and quality.
[0022] Preferably, the surface of the stirring drum is provided with a feeding opening and a discharging opening connected to the interior of the stirring drum.
[0023] By adopting the technical scheme, the adding of the concrete raw materials and the discharging of the finished concrete can be conveniently realized, and the operation convenience and work efficiency are improved.
