An ash inlet pipe 6 is provided at the middle position of the top of the dust reduction box 2, and one end of the ash inlet pipe 6 extends above the spray pipe 21, and one end of the ash inlet pipe 6 is connected to the feeding pipe 4, and the other end of the ash inlet pipe 6 is connected to the feeding pipe 4, and the position of the ash inlet pipe 6 near the feeding pipe 4 is funnel-shaped, and a dust-proof net 20 is provided at the connection of the ash inlet pipe 6 and the feeding pipe 4. An air outlet block 18 is provided on the inner wall of the feeding pipe 4 on the side away from the dust-proof net 20, and a downward-sloping baffle 19 is provided on the inner wall of the feeding pipe 4 above the air outlet block 18. A blower 5 is provided at the top of the crushing box 1 on the side away from the dust reduction box 2, and the output end of the blower 5 extends into the air outlet block 18. The construction waste enters the crushing box 1 through the feeding pipe 4, and then the first crushing shafts 11 drive the crushing drums 12 to rotate to crush the waste. Then the crushed waste drops to the position of the crushing drums 14, and the second crushing shafts 13 drive the crushing drums 14 to rotate to crush the dropped waste, so that the waste can be crushed twice, making the crushing effect better and reducing the probability of blockage. Then it drops onto the sloping screen 15 for filtration. At the same time, the beating shaft 17 can drive the beating pieces 16 to rotate to beat the screen 15 to prevent the screen 15 from being blocked and affecting its filtration effect. When the crushing box 1 is crushing, the rising dust can float into the feeding pipe 4. Then the blower 5 can be started to blow air through the air outlet block 18 towards the dust-proof net 20, and the rising dust-containing gas can be blown to the dust-proof net 20, and then filtered through the dust-proof net 20 and enter the ash inlet pipe 6, and then enter the dust reduction box 2 through the ash inlet pipe 6. The spray pipe 21 can spray and reduce the dust of the dust-containing gas, which can reduce the dust floating out of the device and increase the dust content in the gas in the working site;
[0022] On the inner walls on both sides below the first crushing roller 12, connecting blocks 23 are provided on the inner wall of the crushing box 1. And on each connecting block 23, an inclined plate 24 is fixedly connected through a rotating shaft. And between the bottom of the inclined plate 24 and the inner wall of the crushing box 1, they are connected by a spring 25. After the construction waste is crushed by the first crushing roller 12, it can fall on the inclined plate 24. Through the action of the rotating shaft and the spring 25, the inclined plate 24 buffers the preliminarily crushed waste, can reduce the impact force when it falls on the second crushing roller 14, and can slow down its falling speed, making the crushing effect of the second crushing roller 14 better;

And the other end of the water delivery pipe 8 is connected to the spray pipe 21 inside the dust reduction box 2. After the filtered spray water in the dust reduction box 2 passes through the filter cotton 22, it can return to the water storage tank 3 again, and then the water pump 9 sends it back into the spray pipe 21 through the water delivery pipe 8, which can be recycled and reduce waste;
[0024] Sound-absorbing cotton 10 is provided inside the side wall of the crushing box 1. And on one side of the crushing box 1 corresponding to the downward end of the screen 15, there is an inclined discharge port. In the middle position of the bottom of the crushing box 1, there is a blanking port. And the bottom of the crushing box 1 is funnel-shaped. When the crushing box 1 works, the sound-absorbing cotton 10 inside the side wall can absorb part of the noise generated by crushing, which can reduce the noise pollution of the device. Then, through the funnel shape at the bottom of the crushing box 1, it is convenient for blanking. And when the device is in use, the driving mechanism and the linkage mechanism can drive the first crushing shaft 11, the second crushing shaft 13 and the beating shaft 17 to rotate.
[0025] When the embodiment of the present application is in use, construction waste enters the crushing box 1 through the feeding pipe 4. Then, the first crushing shaft 11 drives the first crushing roller 12 to rotate and crush the waste. After the waste is crushed by the first crushing roller 12, it can fall on the inclined plate 24. The inclined plate 24 buffers the preliminarily crushed waste through the action of the rotating shaft and the spring 25, which can reduce the impact force when it falls on the second crushing roller 14 and slow down its falling speed, making the crushing effect of the second crushing roller 14 better. Then, the second crushing shaft 13 drives the second crushing roller 14 to rotate and crush the fallen waste, which can crush the waste twice, making its crushing effect better and reducing the probability of blockage. Then, it falls onto the screen 15 on the inclined plane for filtration. Larger waste directly discharges through the discharge port and can be collected and crushed again. At the same time, the flapping shaft 17 drives the flapping piece 16 to rotate and flap the screen 15 to prevent the screen 15 from being blocked and affecting its filtration effect. Then, the crushed and filtered waste is discharged through the discharge port. When the crushing box 1 is crushing, the rising dust can float into the feeding pipe 4. Then, the blower 5 can be started to blow air towards the dust-proof net 20 through the air outlet block 18, blowing the rising dust-containing gas to the dust-proof net 20. Then, it is filtered through the dust-proof net 20 and enters the ash inlet pipe 6, and then enters the dust-removing box 2 through the ash inlet pipe 6. The water pump 9 can be started to send the water in the water storage tank 3 into the spray pipe 21 to spray and reduce the dust of the dust-containing gas, which can reduce the dust floating out of the device and increase the dust content in the gas at the working site. The sprayed liquid falls onto the filter cotton 22 for filtration and then re-enters the water storage tank 3 through the connecting pipe 7, which can be recycled and reduce waste. Moreover, when the crushing box 1 is working, the sound-absorbing cotton 10 can absorb part of the noise generated by crushing, reducing the noise pollution of the device.
