[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention;

[0032] Refer to Figures 1-4, a construction waste recycling device for building construction, including a box body 1 and a conveyor belt 2. An inlet is opened above the front side of the box body 1. One side of the conveyor belt 2 is fixedly installed below the inlet. Inside the front side of the box body 1, a crushing box 11 is fixedly installed. Inside the crushing box 11, two crushing rollers 10 are rotatably installed. On the front side of the box body 1, a driving mechanism I 9 is fixedly installed. Both crushing rollers 10 are in transmission connection with the driving mechanism I 9;

[0033] The construction waste that needs to be recycled and crushed can be poured on the conveyor belt 2. After the conveyor belt 2 starts, it can convey the construction waste into the inlet, and through the inlet, it enters the crushing box 11. The driving mechanism I 9 can drive the two crushing rollers 10 to rotate, and the crushing rollers 10 can crush the construction waste.

[0034] At the top inside the box body 1, an air collecting hood 14 is fixedly installed. The air collecting hood 14 is located directly above the crushing box 11. On the top of the box body 1, an air extraction component is fixedly installed. The air extraction component is communicated with the air collecting hood 14;

[0035] The air extraction component can extract air from directly above the crushing box 11 through the air collecting hood 14, and extract the dust generated when crushing the construction waste, avoiding the dust from spreading everywhere and polluting the surrounding environment.

[0036] At the rear side of the crushing box 11, a return mechanism is fixedly installed. At the bottom inside the box body 1, a collection box 5 is placed. Below the rear side of the box body 1, an opening is opened, and the opening is adapted to the collection box 5;

[0037] The construction waste crushed by the crushing box 11 will be discharged from below the crushing box 11. The larger pieces of construction waste will be conveyed to the upper part of the crushing box 11 again through the return mechanism, and the small pieces of waste will pass through the lower part of the return mechanism and enter the collection box 5 for collection. The collection box 5 can be removed from the opening at the rear side of the box body 1, which is convenient for collecting the crushed construction waste.

[0038] Between the left and right sides inside the box body 1, two spray pipes 21 are fixedly installed. On the left side of the box body 1, a water supply component is fixedly installed. The water supply component is communicated with the two spray pipes 21;

[0039] After the water supply component is connected to an external water source, it can spray the external water source into the collection box 5 through the spray pipes 21, so that the construction waste inside the collection box 5 condenses into blocks, making it difficult for the fine construction waste to disperse.

[0040] On the left side of the box body 1, a controller 6 is fixedly installed. The conveyor belt 2, the driving mechanism I 9, the air extraction component, the return mechanism, and the water supply component are all electrically connected to the controller 6. Through the controller 6, the automatic operation of this device can be realized, and the automatic recycling and crushing of construction waste can be realized.

[0041] An active door 13 is installed inside the inlet. On both the left and right sides inside the crushing box 11, inclined guide plates 12 are fixedly installed. The bottom of the crushing box 11 is of an inclined structure, and the lower part at the rear of the crushing box 11 communicates with the inside of the return mechanism.

[0042] The active door 13 can effectively block the dispersion of dust inside the box body 1, and the guide plates 12 can direct the construction waste inside the crushing box 11 towards the two crushing rollers 10.

[0043] The air extraction component includes an air extraction pump 4 and a filter box 3. The input end of the air extraction pump 4 communicates with the inside of the filter box 3. The filter box 3 is connected to the air collection hood 14 through a gas pipeline. Inside the filter box 3, a plurality of detachable filter meshes are fixedly installed.

[0044] The air extraction pump 4 can extract air from inside the box body 1 through the filter box 3 and the air collection hood 14. The drawn air will be filtered by the filter meshes inside the filter box 3, effectively removing the dust dispersed inside the box body 1.

[0045] The return mechanism includes a conveying box 15. On both the left and right sides inside the conveying box 15, conveying cavities are provided. Between the top and bottom of the inner sides of the two conveying cavities, auger rods 16 are rotatably installed. Above and below the front sides of the two conveying cavities, an output port 19 and an input port 18 are respectively provided. The crushing box 11 communicates with the inside of the conveying box 15 through the input port 18. A second driving mechanism 17 is fixedly installed on the top of the conveying box 15. The second driving mechanism 17 is in transmission connection with the two auger rods 16. A number of through holes are provided inside the blades of the two auger rods 16. Filter meshes 20 are fixedly installed at the bottoms of the conveying cavities.

[0046] The second driving mechanism 17 can drive the auger rods 16 to rotate. The crushed construction waste can enter the conveying cavity through the input port 18. The auger rods 16 in the conveying cavity can drive the larger pieces of construction waste to move upward and be conveyed to the crushing box 11 again through the output port 19 for secondary crushing of the construction waste.

[0047] The filter meshes 20 and the through holes can screen out the fine construction waste and collect the construction waste in the collection box 5. Since the crushing rollers 10 will generate relatively large vibrations during the process of crushing the construction waste, and the return mechanism is installed on one side of the crushing box 11, the return mechanism will vibrate together, so as to cooperate with the filter meshes 20 and the through holes to realize the vibration screening of the construction waste.

[0048] Both the first driving mechanism 9 and the second driving mechanism 17 are composed of a motor and a gearbox. The motor is in transmission connection with the gearbox. The gearbox of the first driving mechanism 9 is in transmission connection with the two crushing rollers 10. The gearbox of the second driving mechanism 17 is in transmission connection with the two auger rods 16.

[0049] The water delivery assembly includes a liquid pump 7 and a shunt pipe 8. The output end of the liquid pump 7 is communicated with the shunt pipe 8, and both of the two spray pipes 21 are communicated with the shunt pipe 8. A plurality of atomizing nozzles inclined towards the collection box 5 are fixedly installed on the outer surfaces of the two spray pipes 21.

[0050] The input end of the liquid pump 7 can be connected to an external water source. The liquid pump 7 can transport the water source through the shunt pipe 8 to the two spray pipes 21 and spray it into the interior of the collection box 5 through the atomizing nozzles, so that the construction waste inside the collection box 5 condenses into blocks, facilitating the transportation of the crushed construction waste.
