Description

Technical Field

[0001] This utility model relates to the field of concrete preparation technology, specifically to a homogenizing mixing device for the recycling of slurry in a concrete mixing plant. Background Technology

[0002] During the preparation of a batch of concrete, a concrete mixing plant experiences material leakage during the discharge process via the hopper, resulting in waste. Additionally, after each batch, the mixing tank needs cleaning, which also leads to material waste. To avoid this waste, a common method is to collect the materials and rinse them with water to separate the aggregate and slurry. The aggregate is then re-screened for reuse. The resulting slurry is used as the mixing fluid for the next batch of concrete. This slurry typically contains various powders, and to ensure consistent performance in subsequent concrete batches, its homogeneity must be maintained during reuse. This requires thorough mixing of the slurry collected in the slurry tank. This necessitates the use of a mixing device. However, existing mixing devices are vertically mounted, requiring installation on top of the slurry tank. This not only increases installation difficulty but also obstructs the top of the tank, hindering subsequent cleaning operations. Utility Model Content

[0003] To address the existing technical problems, the main objective of this utility model is to provide a homogenizing mixing device for the recycling of slurry in concrete mixing plants. This mixing device adopts a foldable transmission structure, which can fully mix the slurry inside the slurry tank. During installation, it does not need to be fixedly mounted on the top of the slurry tank; it only needs to be fixedly installed on one side of the slurry tank, thus avoiding large-area obstruction to the top of the slurry tank.

[0004] To achieve the aforementioned technical features, the purpose of this utility model is as follows: a homogenizing mixing device for recycling slurry in a concrete mixing plant includes a main boom, a tail support fixed to one end of the main boom, tail legs symmetrically installed on both sides of the tail support, a first connecting plate symmetrically arranged fixed to one end of the main boom, a second connecting plate hinged to the end of the first connecting plate via hinge bolts, and a secondary boom fixed to the other end of the second connecting plate; a first drive shaft rotatably mounted inside the main boom, the first drive shaft being connected to the second drive shaft via a universal joint assembly, the end of the first drive shaft being used to connect a motor, a tilting power device being installed between the main boom and the secondary boom; a mixing blade being fixedly mounted on the end of the second drive shaft extending out of the secondary boom; and a middle support leg fixed to the outer wall of the first connecting plate.

A first drive shaft 13 is rotatably installed inside the main boom 7. The first drive shaft 13 is connected to a second drive shaft 20 through a universal joint assembly. The end of the first drive shaft 13 is used to connect a motor. A tilting power device is installed between the main boom 7 and the secondary boom 23. The end of the second drive shaft 20 extends out of the secondary boom 23 and is fixedly installed with a mixing blade 24. A middle support leg 29 is fixed on the outer wall of the first connecting plate 16. This mixing device employs a foldable transmission structure, enabling thorough mixing of the slurry inside the slurry tank. During installation, it does not require fixed mounting on top of the slurry tank; it only needs to be fixed to one side, avoiding significant obstruction of the tank's top. In operation, the auxiliary arm 23 is flipped and inserted into the slurry tank 31 using a tilting power device. Then, the motor is started, driving the first drive shaft 13, which in turn drives the second drive shaft 20 via a universal joint assembly. The second drive shaft 20 then drives the mixing blades 24, which thoroughly mix the concrete slurry inside the tank, achieving a homogenized effect.

[0029] Furthermore, a fixing foot plate 1 is provided at the bottom of the tail support leg 2, and the top of the tail support leg 2 is connected to the rectangular frame base 4 through a pin 3.

This universal joint assembly enables power transmission, including vertical power transmission, thus ensuring that the main boom 7 and the auxiliary boom 23 can transmit power even in a vertical position.

[0031] Furthermore, the motor is fixed to one end of the main arm 7 via a motor base 6. The motor base 6 ensures reliable motor fixation. During operation, the motor drives the first drive shaft 13, which in turn drives the second drive shaft 20, which in turn drives the stirring blades 24.

[0032] Furthermore, the tilting power device includes a hydraulic cylinder 9, which is hinged to the top of the main arm 7 via a first hinge seat 8.

[0036] Furthermore, during use, the tail support leg 2 and the middle support leg 29 are fixed to the top of the slurry tank foundation 32 on the side of the slurry tank 31.
