[0002] With the steady development of China's national economy and the acceleration of the urbanization process, the demolition of a large number of old buildings has generated an increasing amount of construction waste. A large amount of construction waste is transported to the suburbs or the outskirts of the city for landfill or open storage, which not only wastes land and resources but also pollutes the environment. It is estimated that the annual amount of waste generated is about 7 billion tons and is still increasing, of which the construction waste is about 3.3 billion tons, accounting for about 50% of the total urban waste. Most of the buildings being demolished are brick-concrete structures, and construction waste bricks account for a considerable proportion in the construction waste generated from the demolition of these buildings. However, traditional concrete production requires a large amount of natural raw materials, such as river sand, aggregates, cement, etc. The mining and processing of these raw materials will cause environmental damage and consume a large amount of energy. Moreover, the traditional methods for treating construction waste are mainly landfill and incineration, which will occupy a large amount of land resources and produce a large amount of pollutants and greenhouse gases. Therefore, how to efficiently utilize resources from construction waste and produce high-strength recycled concrete is an urgent problem to be solved.

[0003] At present, when recycling and processing construction waste, multiple processes are required to achieve the effect of reuse, including operations such as crushing, grinding, and mixing, thus forming an assembly line. This method is not only more troublesome but also requires a large amount of equipment and personnel investment, resulting in low practicability.

Detailed Description of the Preferred Embodiment

[0022] The following further describes the present utility model in conjunction with the embodiments.

[0023] Please refer to Figures 1-4, the present utility model provides a device for preparing high-strength recycled concrete from construction waste, which includes a processing tank 1. A feed box 2 is fixed at the top of the processing tank 1. A servo motor 3 is installed on the outer wall of one side of the feed box 2. Rotating rods 4 are rotatably installed on both inner sides of the feed box 2. Rolling rollers 6 are fixedly installed on the outer walls of the rotating rods 4. Gears 5 are fixed at the other ends of the rotating rods 4. The gears 5 are meshed with each other. A driving pulley 7 is fixed at the other end of one of the rotating rods 4. A mounting rod 8 is rotatably installed on the outer wall of one side of the processing tank 1. A driven pulley 9 is fixed at one end of the mounting rod 8. A belt 10 is tightly connected between the driving pulley 7 and the driven pulley 9. A swinging mechanism 11 is arranged in the middle of the mounting rod 8;

[0024] A transmission rod 14 is rotatably installed at the center of the processing tank 1. A protective member 15 is installed on the outer wall of the transmission rod 14. A transmission mechanism 16 is arranged on the inner wall of the protective member 15.

[0025] Through the swinging mechanism 11, when the eccentric wheel 111 rotates, it can drive the connecting rod 112 to move up and down, thereby driving the connecting piece 113 to move up and down, and further driving the screen 12 to move up and down, so as to improve the swinging effect of the screen 12 and more effectively screen the rolled building materials.

[0026] Furthermore, as Figure 2 , Figure 3 shown, specifically, the swinging mechanism 11 includes an eccentric wheel 111 fixed on the outer wall of the middle of the mounting rod 8. A connecting rod 112 is installed in the inner wall of the eccentric wheel 111 in a limited way. A connecting piece 113 is fixed at the top of the connecting rod 112. A screen 12 is fixed at the top of the connecting piece 113.

[0027] An extrusion spring 13 is installed at the bottom of the screen 12, so that the screen 12 can be reset when the screen 12 moves up and down.

[0028] Furthermore, as Figure 2 , Figure 3 shown, specifically, an extrusion spring 13 is fixed at the bottom of the screen 12. The transmission rod 14 passes through the extrusion spring 13 and the screen 12 and is rotatably installed.

[0029] This solution has the following working process: Pour construction waste into the top of the feeding box 2, and then start the servo motor 3 to drive the rotating rod 4 to rotate. When the rotating rod 4 rotates, it can drive the meshing between the two gears 5, thereby driving the two rolling rollers 6 to rotate towards the same side, so as to crush the construction waste. At the same time, the crushed waste falls into the inner wall of the processing tank 1. When the rotating rod 4 rotates, it can also drive the driven pulley 9 to rotate through the belt 10, thereby driving the mounting rod 8 to rotate. When the mounting rod 8 rotates, it can drive the driving bevel gear 161 to rotate, and then drive the driven bevel gear 162 to rotate. When the driven bevel gear 162 rotates, it can drive the transmission rod 14 to rotate. When the transmission rod 14 rotates, it can drive the flapping rod 20 to rotate. When the flapping rod 20 rotates, it can further flap and crush the falling construction waste, and the flapped waste falls into the inner wall of the screen 12. When the mounting rod 8 rotates, it can drive the eccentric wheel 111 to rotate. When the eccentric wheel 111 rotates, it can drive the connecting rod 112 and the connecting piece 113 to rotate. When the connecting piece 113 moves up and down, it can drive the screen 12 to swing. When the screen 12 moves up and down, it can drive the compression spring 13 to be compressed and stretched, further realizing the rapid swing of the screen 12, thereby improving the filtering efficiency of the waste. At the same time, the waste falls to the bottom end of the inner wall of the processing tank 1. When the transmission rod 14 rotates, it can drive the flattening roller 17 to rotate, further crushing the waste. At the same time, the transmission rod 14 can also drive the brush 18 to rotate, discharging the waste from the discharge port 19 out of the inner wall of the processing tank 1, thus achieving the effect of waste recycling and manufacturing.

[0030] According to the above working process, it can be seen that: Through the swinging mechanism 11, it can mainly drive the screen 12 to swing rapidly, thereby improving the recycling efficiency of the waste. Through the action of the transmission mechanism 16, it can drive the transmission rod 14 to rotate, thereby improving the rolling and discharging efficiency of the waste.

[0031] Furthermore, as Figure 2 , Figure 3 and Figure 4 shown, specifically, the transmission mechanism 16 includes a driving bevel gear 161, and one end of the driving bevel gear 161 is fixed to the other end of the mounting rod 8;

[0032] The transmission mechanism 16 also includes a driven bevel gear 162, the driven bevel gear 162 is fixed to the outer wall of the transmission rod 14, and the driving bevel gear 161 is meshed with the driven bevel gear 162.

[0033] Further, as shown in Figure 1 , Figure 2 , Figure 3 it is worth specifically explaining that a discharge port 20 and a flapping rod 19 are provided on one side of the bottom of the processing tank 1. A flattening roller 17 is rotatably installed on one side of the bottom end of the transmission rod 14, and a brush 18 is installed on the other side of the bottom end of the transmission rod 14.

[0034] Further, as shown in Figure 2 , Figure 3 it is worth specifically explaining that a plurality of flapping rods 20 distributed in parallel are fixed to the top end of the transmission rod 14.

[0035] In summary: Through the swinging mechanism 11, when the eccentric wheel 111 rotates, it can drive the connecting rod 112 to move up and down, thereby driving the connecting member 113 to move up and down. Further, it can drive the screen 12 to move up and down, thereby improving the swinging effect of the screen 12 and enabling it to more effectively screen the rolled building materials.

[0036] The servo motor 3 can be purchased on the market. The servo motor 3 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed. Therefore, it will not be repeated in the specification.
