Description

Technical Field

[0001] This utility model relates to the field of building material recycling technology, specifically a mixing device for recycling waste building materials. Background Technology

[0002] To build a resource-saving and environmentally friendly society, the resource recycling of construction waste must be carried out in areas such as recycled aggregates, recycled concrete and mortar, and the application of construction waste in road engineering. This utilization technology is known as construction waste recycling technology, which has led to a significant increase in investment in road engineering and has attracted much attention in the road industry. Road engineering requires a large amount of earthwork for subgrade construction, which provides an opportunity for the comprehensive utilization of construction waste. Construction waste can be used as earthwork for subgrade filling, but the composition of construction waste is complex, especially with a certain amount of organic matter. Therefore, it is necessary to remove the organic components and unsuitable components for road engineering. In addition, the coarse and fine aggregates of the crushed concrete can be combined with lime or cement to form aggregate, which can be used as a semi-rigid or rigid base layer. This process not only treats construction waste but also reduces earthwork excavation. It is commonly used to process construction waste such as concrete, bricks, and wood, which are crushed, screened, and mixed to generate recycled materials.

[0003] Existing mixing devices for recycling waste building materials typically use a motor-driven stirring rod for single-shaft mixing. This process not only consumes a large amount of electricity but also results in low mixing quality. During mixing, the crushed material tends to stick to the inner wall of the mixing drum, leading to resource waste and making cleaning the inside of the device inconvenient. Therefore, a new mixing device for recycling waste building materials is proposed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This embodiment of a mixing device for recycling waste building materials includes a mounting base 1 and a mixing cylinder 3.

[0023] like Figure 1-4 As shown, the mixing device in this utility model is similar to existing mixing devices. The main improvement of this utility model is that it facilitates the scraping of impurities adhering to the inner wall of the mixing drum 3 during the mixing of waste building materials, making it easier to process and mix the waste building materials multiple times, thus facilitating better processing, mixing, and reuse of the waste building materials. At the same time, it improves the mixing accuracy of the waste building materials. In this utility model, the mixing drum 3 and the motor 24 are both existing technologies. By placing a certain amount of waste building materials inside the mixing drum 3, the worker steps on the pedal 7, causing the pedal 7 to drive the rotating column 4 to rotate through the support plate 6, thereby... The support plate 6 presses down and retracts the telescopic spring 8. At the same time, the rotating column 4 drives the L-shaped plate 10 to rotate through the mounting cylinder 9. The rotating L-shaped plate 10, through the first shaft 11, presses against the mounting plate 13, causing the first connector 12 to rotate. The mounting plate 13 then drives the second connector 14 to rotate through the second shaft 18. Simultaneously, the rotating second connector 14, through the connecting ring 17 and the fixing cylinder 16, drives the rotating rod 15 to rotate. The rotating rod 15 then drives the sealing disc 19 and the scraper 20 to rotate and scrape clean. The rotating sealing disc 19, through the third shaft 21, drives the rotating wheel 22 to rotate and mix.

[0024] like Figure 1-4As shown, the mixing assembly includes a motor 24 mounted on the top of the cover plate 23. The output end of the motor 24 is fixedly connected to a rotating cylinder 25 via a coupling. A mixing rod 26 is mounted on the outer wall of the rotating cylinder 25. When the motor 24 is started, it drives the mixing rod 26 to rotate and mix via the rotating cylinder 25. Thus, the mixing rod 26 and the rotating wheel 22 thoroughly mix the waste building materials inside the mixing cylinder 3.
