A screening cylinder 2 is installed on the upper surface of the machine body 1. A rotating column 3 is rotatably connected to the inner wall of the screening cylinder 2. A first auger 4 is fixedly connected to the outer surface of the rotating column 3. A screening member 5 is installed on the outer surface of the screening cylinder 2. A plurality of sieve holes 6 distributed in a matrix are formed on the outer surface of the screening member 5. A rotating rod 7 is rotatably connected to the inner wall of the machine body 1. A plurality of elastic plates 8 distributed in a circular pattern are fixedly connected to the outer surface of the rotating rod 7. A sieve plate 9 is arranged inside the machine body 1. A vibration motor 10 is installed on the inner wall of the machine body 1. The output end of the vibration motor 10 contacts the bottom end of the sieve plate 9. A conveying cylinder 11 is installed on the inner wall of the machine body 1. A rotating rod 12 is rotatably connected to the inner wall of the conveying cylinder 11. A second auger 13 is installed on the outer surface of the rotating rod 12. Through the cooperation of the installed first auger 4 and the screening member 5, preliminary screening can be carried out to separate stones from gravel and dust, so as to screen out pure stones. Through the cooperation of the sieve plate 9, gravel and dust can be separated, and further screening can be carried out. The separated dust will be discharged from the machine body 1 through the cooperation of the conveying cylinder 11 and the second auger 13, and at the same time, dust emission during the discharge process can be avoided, thereby improving the overall practicability.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 , a feeding cylinder 14 is fixedly communicated with the upper surface of the screening cylinder 2. The first auger 4 contacts the inner wall of the screening cylinder 2. The cooperation of the installed feeding cylinder 14 and the first auger 4 can avoid dust emission during the transportation into the screening cylinder 2, and at the same time, the materials can be transported orderly. Two baffles 15 are fixedly connected to the upper surface of the conveying cylinder 11. Both of the two baffles 15 are fixedly connected to the inner wall of the machine body 1. Installing the baffles 15 can block the dust entering the machine body 1 so that it can enter the conveying cylinder 11 and be transported out of the machine body 1 through the cooperation of the second auger 13. First belt pulleys 16 are fixedly connected to the right ends of the rotating column 3 and the rotating rod 7. The two first belt pulleys 16 are connected by a belt in transmission. Installing the first belt pulleys 16 can transmit power, so that when the rotating column 3 rotates, it drives the rotating rod 7 to rotate, and the rotating rod 7 drives a plurality of elastic plates 8 to beat the screening member 5.

[0033] Please refer to Figure 1 , Figure 2 and Figure 4, a second pulley 17 is fixedly connected to the right ends of both the rotating rod 7 and the swivel rod 12. The two second pulleys 17 are connected by belt drive. Installing the second pulley 17 enables the rotating rod 7 to drive the swivel rod 12 to rotate during the rotation process, so that the swivel rod 12 can convey the dust through the second auger 13 during the rotation process. A drive motor 18 is installed on the right side of the screening cylinder 2. The output end of the drive motor 18 is fixedly connected to the right end of the rotating column 3. The drive motor 18 can drive the rotating column 3 to rotate, and in cooperation with the first auger 4, it can convey the material entering the screening cylinder 2 in an orderly manner. A discharge port 19 is provided on the right side of the machine body 1. A retaining frame 20 is fixedly connected to the left side of the machine body 1. Installing the retaining frame 20 can facilitate the classification and collection of stones and dust, preventing them from piling up together. Two rubber pads 21 are fixedly connected to the bottom surface of the machine body 1. The two rubber pads 21 are symmetrical. Installing the rubber pads 21 can reduce the vibration of the machine body 1 during operation and reduce the noise generated by the vibration of the machine body 1 during operation.

[0034] In a dust, sand, and stone multi-stage separation device in this embodiment, through the cooperation of installing the first auger 4 and the screening member 5, preliminary screening can be carried out to separate stones from gravel and dust, thereby screening out pure stones. Through the cooperation of the sieve plate 9, the gravel and dust can be separated, and further screening can be carried out. The separated dust will be discharged from the machine body 1 through the cooperation of the conveying cylinder 11 and the second auger 13, and at the same time, dust emission during the discharge process can be avoided, thereby improving the overall practicality.

[0035] The working principle of the above embodiment is as follows: First, the drive motor 18 drives the rotating column 3 to rotate. During the rotation process of the rotating column 3, the rotating rod 7 and the swivel rod 12 can be driven to rotate through belt drive. Subsequently, the material is put into the feed cylinder 14. The rotation of the rotating column 3 can drive the first auger 4 to convey the material. When the material passes over the screening member 5, the rotation of the rotating rod 7 can drive multiple elastic plates 8 to slap the bottom end of the screening member 5, enabling the gravel and dust in the screening cylinder 2 to enter the sieve plate 9 through the sieve holes 6. The larger stones will be conveyed out by the first auger 4. When the gravel falls onto the sieve plate 9, the vibration motor 10 starts and transmits the vibration to the sieve plate 9, causing the dust on the sieve plate 9 to fall into the conveying cylinder 11 under the influence of the vibration, while the gravel will be discharged from the machine body 1 through the discharge port 19. The swivel rod 12 can drive the second auger 13 to convey the dust during the rotation process, avoiding dust emission during the dust conveying process, thereby improving the overall practicality.
