[0002] Construction waste refers to waste materials generated during the construction, demolition, maintenance and decoration processes, including bricks, metals, wood, etc. The treatment methods of construction waste include landfill, stacking, recycling and resource treatment. With the improvement of environmental awareness, more and more construction waste is used for resource treatment, such as as recycled aggregate for road paving, foundation filling, etc.

[0003] The patent specification with announcement number CN221132439U discloses a construction waste stone recovery and crushing device, including a crushing shell and a casing fixed to one side of the surface of the crushing shell, and also includes: a power motor fixed to the inner cavity of the casing, the output shaft of the power motor is fixed with a transmission rod, and the surface of the transmission rod is provided with a crushing roller for crushing construction waste; a transmission mechanism for transmission is provided on the surface of the transmission rod, and the surface of the transmission mechanism is provided with a sealing disk; when the utility model is in use, the sealing disk can be rotated under the cooperation of the transmission rod and the transmission mechanism, thereby opening or closing the feeding channel to achieve the effect of batch unloading. In addition, under the action of the connecting mechanism, a buffering effect can be generated between the tray and the expansion piece to avoid the transmission of the impact force of stone unloading. In addition, the expansion piece can be disassembled to facilitate the replacement and maintenance of it by the staff.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned construction waste gravel recovery and crushing device has the following problems: during the stone crushing process, a certain amount of dust and powder will be generated, which will affect the surrounding environment and workers. At the same time, the crushed stones often have a wide particle size distribution and need to be separated before they can be reused. In view of this, a construction waste gravel recovery and crushing device is provided to overcome the above-mentioned defects. Utility Model Content

Through design and coordination, the device can spray water mist into the interior of the box body 1 through the nozzle 6. The water molecules combine with the dust particles to moisten their surface, increase the adhesion between the particles, reduce the suspension and diffusion of the dust, and the mass of the dust particles after wetting increases, and they settle under the action of gravity, reducing the dust concentration in the air. At the same time, sieves of different mesh sizes are set under the box body 1 to separate large-particle crushed matter and water from the crushed matter, reducing the waste of water resources while facilitating further processing of the crushed matter.

[0025] As a further implementation plan of the above technical solution: the first screen 4 is a slope, and the slope of the first screen 4 is inclined downward from the back to the front, and the inclination angle of the first screen 4 is 45 degrees, so that when the first screen 4 is shaken up and down, the large particles of crushed objects remaining above the screen can move toward the front end along the slope.

The stones to be crushed are put into the feed hopper 10. Due to the high humidity inside the box 1, the dust on the surface of the stones and the dust generated by the crushing are moistened by water mist and settle under the action of gravity, thereby reducing the diffusion of dust. When the stones crushed by the crushing roller 11 pass through the first screen 4, the crushed materials with larger particles remain above the first screen 4 and slide out of the box 1 along the inclined direction of the first screen 4. The crushed materials passing through the first screen 4 fall onto the second screen 5, and the residual water is collected in the water storage box 3 under the action of gravity. When the crushed materials reach a certain amount, pull the handle on the water storage box 3, and pull the water storage box 3 out along the chute on the inner wall of the box 1 to recycle the crushed materials and collected water for secondary utilization.
