Description

Technical Field

[0001] The present invention belongs to the technical field of building construction feeding, and in particular relates to a feeding device for assembled concrete building construction. Background Art

[0002] Prefabricated concrete buildings are concrete structures designed and constructed using standardized, factory-produced precast reinforced concrete components through on-site modular assembly. Their core characteristic is the shift from the traditional "cast-in-place" construction model to a "factory prefabrication + on-site assembly" model. By integrating industrialized production with information-based management, they achieve efficiency improvements, quality optimization, and sustainable development throughout the building lifecycle.

[0003] While current feeders used in prefabricated concrete construction can achieve initial mixing with concrete mixers, they still have significant deficiencies in managing aggregate settling and ensuring uniform mixing. Specifically, when aggregate is poured into the mixer, it is susceptible to settling due to gravity, causing large amounts of aggregate to quickly accumulate at the bottom of the mixer, forming a "dead zone" that is difficult to stir. Currently, mainstream mixer designs utilize a single mixing mechanism with vertical rotation. This mixing mode concentrates the disturbance of the concrete mixture primarily around the mixing blades during operation, making it difficult to effectively move the aggregate at the bottom of the mixer upward. This results in inadequate mixing between the bottom aggregate and the upper slurry, significantly compromising the overall mixing efficiency. Even more critical is the heavy accumulation of aggregate at the bottom of the mixer, coupled with the high viscosity of the concrete slurry, during the discharge phase. Blockages can easily form at the discharge port, disrupting construction progress and potentially damaging the mixer and feeder system, increasing equipment maintenance costs. In addition, if the blockage is not dealt with promptly and effectively, it may cause fluctuations in concrete quality and pose a potential threat to the overall performance of prefabricated concrete buildings.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

The discharge port 4 is fixedly connected to a conveying bin 6, a spiral auger shaft 7 is rotatably installed inside the conveying bin 6, and a rolling wheel 8 is rotatably installed inside the discharge port 4. The spiral auger shaft 7 and the rolling wheel 8 are respectively fixedly installed with a first connecting shaft 9 and a second connecting shaft 10, and the first connecting shaft 9 and the second connecting shaft 10 are respectively fixedly installed with a first transmission wheel 11 and a second transmission wheel 12, and the first transmission wheel 11 and the second transmission wheel 12 are connected to a third transmission wheel 14 through a transmission belt 13, and the third transmission wheel 14 is fixedly installed on a third connecting shaft 15, and the third connecting shaft 15 is connected to a drive motor 16 through a transmission mechanism.

[0034] The working principle of the feeding device for assembled concrete building construction proposed by the present invention is that when concrete needs to be fed into the precast mold, the concrete raw materials can be poured into the concrete mixing box 1, and then the drive motor 16 is started.

The spiral blade 3 can transport the concrete raw materials at the bottom of the concrete mixing box 1 upward, and then evenly mix the concrete raw materials.

[0035] After waiting for mixing to be completed, the switch valve 5 is opened. At this time, the stirred concrete is discharged from the discharge port 4. It is worth noting that the driving motor 16 is not turned off at this time. The output end of the driving motor drives the transmission mechanism to move, thereby driving the third connecting shaft 15 to rotate, and then driving the third transmission wheel 14 to rotate, thereby driving the first transmission wheel 11 and the second transmission wheel 12 to rotate through the transmission belt 13, and then driving the first connecting shaft 9 and the second connecting shaft 10 to rotate, thereby driving the rolling wheel 8 and the spiral auger shaft 7 to rotate.
