The lower end of the connecting pipe 6 extends to the lower surface of the circular plate 3 and communicates with the interior of the processing chamber 2.

[0026] Furthermore, the dust collecting mechanism also includes an exhaust fan 8 and a water spray box 9. The exhaust fan 8 is fixedly mounted on the rear surface of the mounting box 5, and the front end of the exhaust fan 8 extends to the interior of the mounting box 5.

A circular groove 10 is provided inside the circular plate 3, and a plurality of through holes for spraying water are provided on the lower surfaces of the circular plate 3 and the water spray box 9.

[0027] Furthermore, the dust floating in the feed pipe 4 is sucked into the rear end of the installation box 5 by the exhaust fan 8. At this time, the water flowing out of the water spray box 9 brings the dust floating to the rear end of the installation box 5 to the interior of the processing warehouse 2 through the connecting pipe 6, so that the floating dust can be directly recycled, reducing the operation steps from dust collection to recycling, reducing the labor intensity of workers, and improving the working efficiency of the device.

[0031] Furthermore, a mounting rod 15 is fixedly installed on the inner wall of the processing chamber 2, and a mounting groove 16 is opened inside the mounting rod 15. A motor 17 is fixedly installed on the left surface of the processing chamber 2. The output end of the motor 17 rotates and passes through the interior of the mounting groove 16.

[0033] Working principle: When using this dust collecting device, asphalt concrete powder can be added to the interior of the processing bin 2 through the feed pipe 4. Before adding, the exhaust fan 8 and the water pump 11 can be started, so that the water pump 11 draws water through the water pumping pipe 13 and then transports it to the interior of the water supply pipe 12, so that the water enters the spray box 9 and the circular groove 10 respectively through the water supply pipe 12. The water entering the spray box 9 and the circular groove 10 goes out through the water spray holes under the circular plate 3 and the spray box 9. At this time, the asphalt concrete powder is added to the interior of the processing bin 2 through the feed pipe 4. When the asphalt concrete powder passes through the feed pipe 4, most of the asphalt concrete powder enters the interior of the processing bin 2, and a small amount of dust floating in the feed pipe 4 is sucked into the interior of the installation box 5 by the exhaust fan 8. When the dust reaches the rear end of the installation box 5, it is sprayed The water flowing out of the water tank 9 is carried to the inside of the connecting pipe 6, and then enters the inside of the processing bin 2 through the connecting pipe 6. The setting of the mounting rod 15 can prevent the asphalt concrete powder from directly entering the inside of the mounting box 5 when it falls. When the asphalt concrete powder falls into the inside of the processing bin 2, the water inside the circular groove 10 is retained because of the water spray holes opened under the circular plate 3. When the asphalt concrete powder enters the bottom of the processing bin 2, the dust of the asphalt concrete powder cannot be lifted up, or after being lifted up, it is brought back to the bottom of the processing bin 2 by subsequent water, preventing the dust that falls to the bottom of the processing bin 2 from being lifted up and returning to the inside of the feed pipe 4 and going out from the feed pipe 4, polluting the workers' working environment and affecting the workers' work efficiency. After that, the motor 17 can be started to drive the stirring rod 7 to rotate to process the added asphalt concrete powder.
