The second dust box 54 and the second negative pressure fan 53 are fixedly mounted on the support plate 17. The dust hood 55 absorbs dust that falls from the first sieve plate 32 and deposits it in the second dust box 54. A second cleaning door is provided on one side of the second dust box 54 to facilitate cleaning and removal of dust from the second dust box 54. A filter is provided at the connection between the second negative pressure fan 53 and the second dust box 54 to prevent dust from affecting the second negative pressure fan 53.

[0038] A collection box 19 is located at the bottom of the housing 1. The sieve holes on sieve plates 3 10, 42, and 32 decrease in size from top to bottom. This allows smaller aggregates to be collected without affecting the properties of the cement being produced. The sieve holes on sieve plates 3 10, 42, and 32 decrease in size from top to bottom, allowing aggregates of varying sizes to fall through. This prevents aggregate clogging and speeds up the screening process.

[0039] The working principle of the cement stabilized regenerated crushed stone aggregate dust removal device provided by the utility model is as follows:

[0040] Before use, turn on the vibration motor 1 21, the two vibration motors 28, the motor 39, the screening motor 41, the negative pressure fan 1 51 and the negative pressure fan 2 53, turn the handle 1 on the cover 12 to open the feed port 11, and pour the aggregate into the box body 1 from the feed port 11. After all the aggregate is poured into the box body 1, turn the handle 1 on the cover 12 to close the feed port 11 to prevent dust from leaving the feed port 11 and the aggregate entering the box body 1 from falling onto the vibration plate 25. After the vibration motor 1 21 is started, the elliptical wheel 1 23 starts to rotate, and the fixed rod 1 24 prevents the moving direction of the vibration plate 25 from deviating. After the vibration motor 2 28 is started, the elliptical wheel 2 27 starts to rotate, and the fixed rod 2 26 makes the vibration The moving direction of the plate 25 does not deviate, and at the same time, it provides support force for the vibration plate 25, increases the stability of the vibration plate 25, and the up and down movement of the vibration plate 25 can better remove the dust on the aggregate. At the same time, the inclination of the vibration plate 25 makes the aggregate move toward the screen plate three 10, and the negative pressure fan 1 51 collects the dust inside the box body 1 and collects the dust in the dust box 1 52. The dust box 1 52 is provided with a cleaning door 1 at the corresponding position outside the box body 1, which can remove and clean the dust in the dust box 1 52. The sieve holes on the screen plate three 10 are screened for the first time to make small aggregates fall, and the other aggregates move toward the screen plate two 42. After the screening motor 41 is started, the rotating shaft 46 makes the disc 43 connect to the annular connecting seat 44 rotates, so that the annular connecting seat 44 drives the connecting plate 45 to move, and the connecting plate 45 causes the sieve plate 2 42 to start moving back and forth. The length of the sieve plate 2 42 in the box body 1 does not change at all, which can better remove the dust on the aggregate on the sieve plate 2 42. At the same time, the sieve holes on the sieve plate 2 42 can speed up the screening rate, because the inclination angle of the sieve plate 2 42 makes the aggregate that has not fallen from the sieve holes slide onto the sieve plate 1 32. After the motor 39 is started, the transmission wheel 2 36 starts to rotate, and the conveyor belt 35 causes the transmission wheel 1 34 to start rotating. A card slot corresponding to the card block is provided on the transmission wheel 1 34, so that the connecting rod 33 fixedly connected to the card block also starts to rotate and move back and forth, so that the sieve plate 1 32 is moved back and forth on the limit plate 3 1 moves left and right, there are sieve holes on the sieve plate 1 32, which can screen smaller aggregates and make them fall into the collection box 19 below, the dust hood 55 absorbs the dust falling from the sieve plate 1 32, and the dust is stored in the dust box 2 54. There is a cleaning door 2 on one side of the dust box 2 54, which is convenient for cleaning and removing the dust in the dust box 2 54. A filter is provided at the connection between the negative pressure fan 2 53 and the dust box 2 54 to prevent dust from affecting the negative pressure fan 2 53. A discharge door 13 is installed at the front end of the box body 1, and the discharge door 13 is the place where the collection box 19 is taken out. At the same time, the movement of the sieve plate 1 32 can avoid the accumulation of aggregates inside the box body 1, and at the same time, the aggregates that meet the requirements leave from the sieve plate 1 32 through the discharge port.
