Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing, in particular to a concrete mixing device for water conservancy construction. Background Art

[0002] As an indispensable and important equipment in water conservancy project construction, the development and application of water conservancy construction concrete mixing device is of great significance to improving project quality and accelerating construction progress. Traditional concrete mixing devices have problems such as low mixing efficiency and serious dust, and cannot meet the high standards and high requirements of modern water conservancy projects for concrete mixing.

[0003] In a water conservancy construction concrete mixing device with publication number CN219768675U, it involves the technical field related to the mixing device, including a support frame, a limit plate is fixedly installed on the upper end of the support frame, a mixing drum is fixedly installed inside the limit plate, a detachable support plate is provided on the upper end of the mixing drum, a motor is fixed at the top center of the support plate, a support rod is fixed on the output shaft of the motor, a mixing paddle is fixedly installed on the outer wall of the support rod, and a breaking drum is fixed on the outer wall of the upper end of the support rod. By arranging a detachable support plate at the top of the mixing drum, the support plate is used to drive the disassembly of the stirring paddle, thereby changing the traditional non-detachable design between the stirring paddle and the mixing drum, so as to facilitate the cleaning of the mixing drum and the stirring paddle. In addition, the rotation of the support rod drives the breaking drum to rotate, so that the breaking drum can disperse the concrete into the interior of the mixing drum, and at the same time, the concrete inside the mixing drum can be prevented from jumping out, which is convenient for the use of the mixing device. When the above-mentioned existing device is in use, the concrete is only stirred by the cooperation of the support rod and the stirring paddle. The stirring method is single and the stirring range has certain limitations, resulting in limited stirring effect on the concrete. In addition, during the stirring process, the concrete is easily adhered to the inner wall of the device, which on the one hand reduces the utilization efficiency of the concrete. On the other hand, the concrete adhesion increases the later cleaning burden, and the stirred concrete is inconvenient to be transported in time. Therefore, corresponding improvements can be made.
