[0002] Construction waste refers to the waste generated by people in the production activities of the construction industry such as demolition, construction, decoration, and repair. Construction waste usually includes demolition waste, building residues, decoration waste, and construction waste. The treatment and reuse of construction waste is an important part of construction management. If construction waste is not properly handled, it will cause environmental pollution and waste of land resources. Among them, demolition waste includes concrete blocks, bricks, sand and gravel, and rubble.
[0003] In order to avoid the above problems, the prior art often classifies construction waste at the source of its generation, separates it according to different types of materials, and then facilitates subsequent processing and recycling. The classified construction waste can be used as construction sand, filling materials or roadbed materials, etc.
[0004] For example, Chinese patent document CN116605674A discloses a construction waste classification system. The construction waste classification system reduces the frequency of technicians replacing collection boxes by setting up a sorting mechanism and a transposition mechanism, reduces the possibility of metal in the collection box falling due to accumulation, improves the intelligence and automation of the construction waste classification system, and reduces the workload of technicians.
[0005] However, in actual use, it is difficult to separate concrete blocks and steel bars during the recycling of concrete blocks in the construction waste treatment equipment of the above-mentioned construction waste classification system.

[0031] A construction waste classification and recycling brick-making vehicle proposed in the embodiment of the utility model sequentially arranges a rolling device 3, a crushing device 4, a screening device 7 and a brick-making device 9 on the walking chassis, and sequentially performs rolling, crushing, screening and brick-making operations on the construction waste, so that the metal and non-metal waste in the construction waste are separated. In particular, the recycling rate of the steel bars in the concrete blocks is improved. In addition, the construction waste classification and recycling brick-making vehicle uses a transmission channel 6 to connect the crushing device 4 and the brick-making device 9, and the powder in the crushed material is transported to the brick-making device 9 in advance, so that the screening device 7 can subsequently screen out material particles of different particle sizes step by step, which is suitable for different recycling and reuse scenarios. In this way, the recycling rate of construction waste is improved, especially the recycling and processing of concrete blocks, the processing steps of concrete blocks are optimized, and the recycling and reuse rate of concrete blocks is improved.
[0032] like Figure 1 As shown, a construction waste classification and recycling brick making vehicle comprises a traveling chassis, a cab 1 and a processing device mounted on the traveling chassis. The processing device comprises a rolling device 3, a crushing device 4, a screening device 7 and a brick making device 9 arranged in sequence on the traveling chassis. For example, a crawler 2 is provided on the traveling chassis to improve the mobility of the equipment, so that the traveling chassis is suitable for more complex terrain environments.
[0033] like Figure 2 Combination Figure 3As shown, a rolling chamber for crushing concrete blocks is provided inside the rolling device 3. A steel bar recovery port 16 is provided on one side of the rolling chamber. A rotating magnetic roller 15 for adsorbing steel bars is provided between the steel bar recovery port 16 and the rolling chamber.

[0034] like Figure 2 Combination Figure 4 As shown, the crushing device 4 is used to crush the material conveyed through the material guide surface 19. A conveying channel 6 is provided on the top of the crushing device 4. Figure 6 As shown, the conveying channel 6 is connected to the feeding trough 26 of the brick making device 9.
[0035] like Figure 2 As shown, the feed port 24 of the screening device 7 is connected to the discharge port of the crushing device 4. A plurality of discharge ports are sequentially arranged on the side wall of the screening device 7 along the direction of material conveying. For example, the first discharge port 12, the second discharge port 13 and the third discharge port 14 are sequentially arranged on the side wall of the screening device 7 along the direction of material conveying. A numerical control table 8 is arranged on the side wall of the screening device 7, and the numerical control table 8 is used to control the screening process in real time to improve the controllability of the screening device 7.
[0036] like Figure 6 As shown, an aging box 29 is provided inside the brick making device 9. A feeding port 27 is provided on the top of the aging box 29. A feeding trough 26 is connected to the aging box 29. A powder outlet 28 is provided on the side wall of the aging box 29. A brick making mold 11 is provided at the powder outlet 28.
[0037] The powdered material undergoes a chemical reaction in the aging box 29, and the temperature in the aging box 29 reaches 1800°C-1900°C to ensure that the chemical reaction is fully carried out. The final product flows out from the powder outlet 28 and flows into the brick-making mold 11 to obtain a finished brick. The operator can add additional materials such as slaked lime, saltpeter and water to the aging box 29 through the addition port 27.
[0038] like Figure 1 As shown, a ladder 10 is provided on the outside of the brick making device 9. The ladder 10 is located on a side close to the brick making mold 11. In this way, the ladder 10 is used to reduce the difficulty of the operator climbing to the top of the brick making device 9, so that the operator can add additional materials for brick making into the aging box 29 through the adding port 27.
[0039] like Figure 3As shown, a pair of rolling shafts are arranged in the rolling chamber. The first rolling shaft 17 and the second rolling shaft 18 are arranged in parallel. Such an arrangement facilitates rapid crushing of the concrete block, is conducive to separating the steel bars in the concrete block, and improves the crushing and separation effect of the concrete block. For example, the first rolling shaft 17 and the second rolling shaft 18 are both hexagonal prism shafts.
[0040] like Figure 4 As shown, the crushing device 4 is provided with crushing blades 21. In this way, the crushing blades 21 are used to further crush the material, crushing the crushed concrete fragments into fine particles, which is beneficial to the subsequent processing of the screening device 7. The side wall of the crushing device 4 is provided with a wire burying point 23. Figure 1 As shown, a power starter 5 is provided on the top of the crushing device 4, and the power starter 5 is used to control the crushing device 4 to be turned on or off.
[0041] like Figure 4 As shown, a blower 22 for blowing the crushed material into the conveying channel 6 is provided at the bottom of the crushing device 4. In this arrangement, the blower 22 blows air upward at the bottom of the crushing device 4, and the powdered material in the crushed material enters the conveying channel 6 under the action of wind force, and enters the brick making device 9 as a raw material for brick making through the conveying channel 6. Combined with the wind force of the blower 22 and the action of gravity, the crushed material is initially screened and separated, thereby improving the recycling rate of construction waste.
[0042] like Figure 5 As shown, a filter plate 20 is provided inside the screening device 7. The filter plate 20 is provided with filter holes. The aperture of the filter hole increases successively along the direction of material conveying. Such an arrangement facilitates the step-by-step screening of the crushed material, so that the construction waste can be recycled and applied to different usage scenarios.

For example, the screening device 7 is used to obtain gravel larger than 20 mm for road base materials, 0.3 mm-5 mm sand for adjusting the concrete mix ratio, and 5 mm-20 mm material for filling materials.
[0043] like Figure 5 As shown, the filter plate 20 is arranged obliquely toward one side of the discharge port. This arrangement facilitates the material to be discharged from the screening device 7 through the discharge port.

In this way, the vibration column 25 is used to drive the filter plate 20 to vibrate, thereby further improving the screening effect; on the other hand, the vibration column 25 is used to provide power for the material on the filter plate 20 to move along the material conveying direction.
[0045] When used, a construction waste classification and recycling brick-making vehicle proposed in the embodiment of the utility model includes the following steps: in the rolling and separation stage, the construction waste is first sent into the rolling chamber of the rolling device 3, which is mainly used to crush large pieces of concrete. At the same time, the rotating magnetic roller 15 in the rolling chamber will absorb the steel bars and separate them through the steel bar recovery port 16, thereby realizing the preliminary classification of metal and non-metal materials in the construction waste.
[0046] In the fine crushing stage, the crushed material is transported downward to the crushing device 4 through the material guide surface 19, and the material is further crushed into smaller particles to facilitate subsequent screening and brick making.
[0047] In the screening stage, the crushed material is transported to the screening device 7, and the material is classified according to different particle sizes through multiple discharge ports of the screening device 7. This step can ensure that the material meets the quality requirements in the subsequent brick making.
[0048] In the brick preparation stage, the screened materials suitable for brick making enter the feed trough 26 of the brick making device 9 through the conveying channel 6, and then are transported to the aging box 29. In the aging box 29, an appropriate amount of water or other auxiliary materials can be added to the materials as needed to perform aging treatment to improve the quality of the final bricks. The aged materials are transported to the brick making mold 11 through the powder outlet 28 for pressing and forming to finally form bricks.
[0049] The whole process realizes the on-site classification, treatment and resource utilization of construction waste, which not only reduces the transportation and disposal costs of waste, but also realizes the efficient recycling and utilization of construction waste, contributing to environmental protection and sustainable development. The construction waste classification and recycling brick-making vehicle proposed in the embodiment of the utility model integrates multiple processing links into one, greatly improving work efficiency and reducing the impact on the environment.
