[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, by setting up a rotating shaft and blades for use together, can drive the rotating shaft to rotate when the crushing roller is running, and the rotating shaft drives the blades to rotate, thereby drawing gas out of the crushing device body and putting the crushing device body into a negative pressure state, thereby reducing the possibility of dust leakage and achieving the purpose of dust prevention.

[0014] 2.

In case of an accident, the crushing roller can be stopped quickly, ensuring the response speed of the crushing roller to stop suddenly.

[0016] 4. In this invention, when the rotating shaft rotates, it also drives the cleaning rod and the air-guiding back-blowing mechanism to rotate. The rotating cleaning rod drives the brush to rotate, so that the brush continuously brushes away the dust adsorbed on the outer wall of the dust filter. When the rotating disc body and the air-guiding ear of the air-guiding back-blowing mechanism rotate, air can be introduced into the guide hole. The gas entering the guide hole passes through the blowpipe and is blown out through the blowhole. The blown gas blows back towards the dust filter, blowing air in the opposite direction to clear the dust filter. When the rotating shaft rotates, it also drives the blowpipe to rotate, so that the blowpipe can clean the entire surface of the dust filter, ensuring that the dust filter is not easily blocked.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Please see Figures 1 to 9 An environmentally friendly construction waste treatment device with dust prevention function includes a crushing device body 1 and two crushing rollers 2. The outer wall of the crushing device body 1 is provided with a discharge port 3 and a feed port 4 respectively. One of the crushing rollers 2 passes through the crushing device body 1 and extends to the outside of the crushing device body 1. A drive connection mechanism is sleeved on one end of the crushing roller 2 located outside the crushing device body 1. A dust filter shell 5 is fixedly connected to the outer wall of the crushing device body 1 and is connected to the crushing device body 1. A discharge sealing mechanism is provided at the lower end of the dust filter shell 5 and a suction shell 6 is connected to the side wall of the dust filter shell 5. A rotating shaft 7 is rotatably connected to the inner wall of the suction shell 6 and blades 8 are fixedly connected to the outer wall of the rotating shaft 7. A dust filter 9 is sleeved on the outer wall of the rotating shaft 7 and is fixedly connected to the dust filter shell 5. An exhaust hole 10 is provided at one end of the suction shell 6.

[0021] As can be seen from the above structure, by setting the rotating shaft 7 and the blades 8 to work together, when the crushing roller 2 is running, the driving connection mechanism can make the crushing roller 2 drive the rotating shaft 7 to run, and the running rotating shaft 7 drives the blades 8 to run, thereby drawing out the gas in the main body 1 of the crushing device, thereby making the main body 1 of the crushing device under negative pressure, thereby reducing the possibility of dust leakage and achieving the purpose of dust prevention.

[0022] Furthermore, the drive connection mechanism includes a counterweight drive wheel 11 sleeved on the outer wall of the crushing roller 2, and a cavity 12 is formed on the inner wall of the counterweight drive wheel 11. A spring 13 is fixedly connected to the inner wall of the cavity 12, and a first wedge 14 is fixedly connected to one end of the spring 13. A second wedge 15 is fixedly connected to the outer wall of the crushing roller 2, and the second wedge 15 is located on one side of the first wedge 14. A driven wheel 16 is fixedly connected to one end of the rotating shaft 7, and a transmission belt 17 is fixedly sleeved on the outer wall of the driven wheel 16 and the counterweight drive wheel 11. By setting the counterweight drive wheel 11 and the driven wheel 16 to work together, the crushing roller 2 can be driven to crush the powder. When the crushing roller 2 rotates, the rotating crushing roller 2 can drive the rotating shaft 7 to rotate through the counterweight drive wheel 11 and driven wheel 16, thereby drawing out the gas in the main body 1 of the crushing device, thus making the main body 1 of the crushing device a negative pressure state; and when the device stops, the counterweight drive wheel 11 can continue to rotate due to inertia, so that the counterweight drive wheel 11 can continue to drive the rotating shaft 7 to continue to run for a period of time before stopping, ensuring that the dust generated by crushing is cleaned up before the rotating shaft 7 stops running, thus avoiding a certain amount of dust from overflowing when the device stops.

[0023] Furthermore, the discharge sealing mechanism includes a sealing roller 18 rotatably connected to the dust filter housing 5, and the upper surface of the sealing roller 18 is provided with an inclined surface 19, the lower surface of the sealing roller 18 is provided with a groove, and a counterweight 20 is fixedly connected to the inner wall of the groove. The sealing roller 18 is made of a lightweight material. By setting the sealing roller 18, dust falls on the inclined surface 19, and the dust falling on the inclined surface 19 slides along the inclined surface 19, causing the dust to accumulate on one side of the inclined surface 19, thereby changing the weight distribution of the sealing roller 18. After the dust reaches a certain mass, the dust will press the sealing roller 18 and be discharged. After the dust is discharged, the sealing roller 18 is reset, so that it can seal one end of the dust filter housing 5.

[0024] Furthermore, one end of the rotating shaft 7 passes through the dust filter housing 5, and a cleaning rod 21 is fixedly connected to the outer wall of the rotating shaft 7. A brush 22 is fixedly connected to one side wall of the cleaning rod 21, and one side wall of the brush 22 contacts the dust filter 9. An air-guiding back-blowing mechanism is fixedly connected to the end of the rotating shaft 7 away from the driven wheel 16. By setting the brush 22 and other components for use, when the rotating shaft 7 rotates, the rotating shaft 7 can also drive the cleaning rod 21 and the air-guiding back-blowing mechanism to rotate. The rotating cleaning rod 21 drives the brush 22 to rotate, so that the brush 22 continuously brushes away the dust adsorbed on the outer wall of the dust filter 9.

[0025] Furthermore, the air-guiding back-blowing mechanism includes multiple interconnected air-guiding discs 23. One end of the rotating shaft 7 is provided with a guide hole 24, and the outer wall of the rotating shaft 7 is fixedly connected with a blowpipe 25 communicating with the guide hole 24. One end of the blowpipe 25 is provided with a blowhole 26. When the air-guiding disc 23 of the air-guiding back-blowing mechanism rotates, air can be introduced into the guide hole 24. The gas entering the guide hole 24 passes through the blowpipe 25 and is blown out through the blowhole 26. The blown gas blows back towards the dust filter 9, blowing air in the opposite direction to the dust filter 9 to clear the dust filter 9. When the rotating shaft 7 rotates, the rotating shaft 7 also drives the blowpipe 25 to rotate, so that the blowpipe 25 can clean the entire surface of the dust filter 9 to ensure that the dust filter 9 is not blocked.

[0026] Furthermore, the air guide turntable 23 includes a turntable body 231, and an air inlet 232 is provided on the outer wall of the turntable body 231. An air inlet 233 is provided on one side of the air inlet 232, and the air inlet 233 is fixedly connected to the turntable body 231. The air inlet 232 can increase the amount of air introduced into the air guide turntable 23.

[0027] Furthermore, a one-way sealing pad 27 is fixedly connected to one side wall of the discharge port 3; by setting the one-way sealing pad 27, the one-way sealing pad 27 can seal the discharge port 3, and when discharging, the one-way sealing pad 27 can be pressed open to discharge the material.

[0028] Furthermore, a rotating rod 28 is fixedly connected to the inner wall of the feed inlet 4, and multiple sealing plates 29 are rotatably sleeved on the outer wall of the rotating rod 28. A spring 30 is sleeved on the outer wall of the rotating rod 28, and one end of the spring 30 is fixedly connected to the rotating rod 28, while the other end of the spring 30 is fixedly connected to the sealing plate 29. By setting the sealing plate 29, the feed inlet 4 can be sealed. When feeding, the material can press open the sealing plate 29 to feed.

[0029] In this invention, the crushing roller 2 can be started for use. When in use, the construction waste to be crushed is put in through the feed port 4. At this time, the construction waste will push open the sealing plate 29 and enter the crushing device body 1. The construction waste inside the crushing device body 1 is crushed by the crushing roller 2. The crushed construction waste is discharged through the discharge port 3 by pushing open the one-way sealing pad 27. Furthermore, when the crushing roller 2 is running, the running crushing roller 2 drives the counterweight drive wheel 11 to rotate. The rotating counterweight drive wheel 11 drives the driven wheel 16 to rotate through the transmission belt 17. The rotating driven wheel 16 drives the rotating shaft 7 to rotate. The rotating shaft 7 drives the blades 8 to rotate. The rotating blades 8 draw out the gas in the suction shell 6 and the dust filter shell 5 and filter it, so that the dust filter shell 5 draws out the gas in the main body 1 of the crushing device, thereby making the main body 1 of the crushing device under negative pressure, thereby reducing the possibility of dust leakage and achieving the purpose of dust prevention. Furthermore, when the rotating shaft 7 rotates, it can also drive the cleaning rod 21 and the air-guiding back-blowing mechanism to rotate. The rotating cleaning rod 21 drives the brush 22 to rotate, so that the brush 22 continuously brushes away the dust adsorbed on the outer wall of the dust filter 9. When the rotating disc body 231 and the air-guiding ear 233 of the air-guiding back-blowing mechanism rotate, air can be introduced into the guide hole 24. The gas entering the guide hole 24 passes through the blow pipe 25 and is blown out through the blow hole 26. The blown gas blows back towards the dust filter 9, blowing air in the opposite direction to clear the dust filter 9. When the rotating shaft 7 rotates, it also drives the blow pipe 25 to rotate, so that the blow pipe 25 can clean the entire surface of the dust filter 9. The cleaned dust falls onto the inclined plane 19. The dust on the inclined plane 19 slides along the inclined plane 19, causing the dust to accumulate on one side of the inclined plane 19, thereby changing the weight distribution of the sealing roller 18. When the dust reaches a certain mass, the dust will press the sealing roller 18 and be discharged. After the dust is discharged, the sealing roller 18 returns to its original position. When the crushing roller 2 stops, the counterweight drive wheel 11 can continue to rotate due to inertia, so that the counterweight drive wheel 11 can continue to drive the rotating shaft 7 and other components to continue to run for a period of time before stopping. This ensures that the dust generated by crushing is cleaned up before the rotating shaft 7 and other components stop running, thus preventing a certain amount of dust from overflowing when the device stops. Furthermore, when the crushing roller 2 stops suddenly, the counterweight drive wheel 11 does not need to stop running at the same time. This reduces the braking force required for the emergency stop of the crushing roller 2, making it easier for the crushing roller 2 to stop suddenly. In case of an accident, the crushing roller 2 can be stopped quickly, ensuring the response speed of the emergency stop crushing roller 2.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
