The suction system is a device that uses the negative pressure principle to achieve gas suction, and is commonly used in industrial production, environmental protection and other fields. The suction system is usually composed of a suction port, a pipeline and an exhaust fan, etc. Its working principle is to use an exhaust fan and other equipment to generate negative pressure, so that air enters the pipeline from the suction port and then is discharged to a designated place.

[0036] Equipment such as dust collectors and filters are provided in the feed box 13 and the storage chamber 14 to separate dust and gas, so that clean gas is discharged from the feed box 13 and dust is collected and stored in the storage chamber 14 .

[0037] The air outlet 8 is located at one end of the limiting frame 7 and is fixed with a guide port 9, and the guide port 9 is located in the installation groove. A rubber ring 10 is provided on the guide port 9, and a fixing rod 11 is fixed inside the rubber ring 10;

[0038] The rotating storage mechanism includes a moving groove 12, a feed box 13, a storage cavity 14, a rotating storage unit and a sliding unit. The feed box 13 is arranged in the mounting groove through the sliding unit. The moving groove 12 is opened on the feed box 13 and is located in the mounting groove, and the outer part of the rubber ring 10 contacts the moving groove 12. Four storage cavities 14 are opened in the feed box 13. During the rotation of the feed box 13, the moving groove 12 is attached to the rubber ring 10 to slide and cooperate with the rotating storage unit so that any storage cavity 14 can be located on the horizontal plane with the guide port 9 for storage.

[0039] The rotating storage unit includes a spring 15, a baffle 16, an inclined block 17, a slide rail 30 and a driving unit. A spring groove is provided on the side of the storage cavity 14 close to the mounting groove, and one end of the spring 15 is welded to the spring groove, and the other end of the spring 15 is welded to the baffle 16. The baffle 16 is located inside the storage cavity 14 and can contact or move away from the inner wall of the storage cavity 14 as the fixed rod 11 moves. The two inclined blocks 17 are both arranged on the baffle 16 and located in the movable groove 12. The slide rail 30 is opened in the movable groove 12, and the fixed rod 11 can slide in the slide rail 30.

[0040] The driving unit includes an insertion rod 23, a gear ring 27, a gear 28 and a motor 29. One end of the insertion rod 23 is arranged in a mounting groove opened in the limit frame 7, and one end of the motor 29 is arranged at the other end of the insertion rod 23. The other end of the motor 29 is connected to a rotating rod, and a gear 28 is provided on the rotating rod. The gear ring 27 is arranged in a groove opened in the middle part of the feed box 13, and the gear ring 27 and the gear 28 constitute an engaging connection structure.

[0041] The implementation principle of the machine-made sand dust removal device in the embodiment of the present application is as follows: first, pick up the handle 26 and insert the feed box 13 into the installation groove opened in the limit frame 7. At this time, the groove in the middle of the feed box 13 contacts the insertion rod 23, so that the gear ring 27 and the gear 28 form a meshing connection structure, and when the feed box 13 enters the interior of the installation groove, the spring 21 is compressed, and the slide groove 22 rolls outside the feed box 13, and the slider 21 slides in the movable grooves on both sides of the rolling cavity 18, and the feed box 13 is continuously moved into the limit frame 7 until the slide groove 22 contacts the groove opened on the outside of the feed box 13 for the slide groove 22 to slide. When the limit is completed between the feed box 13 and the limit frame 7, the rubber ring 10 contacts the movable groove 12, and the two fixed rods 11 enter the slide rails 30 respectively, and the installation of the feed box 13 and the limit frame 7 is completed. When the motor 29 is started, the gear 28 is driven to rotate, so that the gear ring 27 also rotates and drives the feed box 13 to rotate inside the limit frame 7, and the slide groove 22 slides in the groove opened in the feed box 13. As the feed box 13 rotates, the movable groove 12 rotates in contact with the rubber ring 10, and the slide rail 30 rotates in contact with the fixed rod 11. When the fixed rod 11 contacts the inclined block 17, the spring 15 is stretched and the inclined block 17 is squeezed into the storage chamber 14, so that a groove for stone powder to pass through is formed between the storage chamber 14 and the rubber ring 10, and the rotation of the motor 29 can be stopped, so that the above-mentioned groove can always be used for stone powder to pass through and enter the inner cavity of the storage chamber 14.

[0042] When turning the handle 6, the threaded connection between the screw groove 3 and the threaded rod 4 drives the baffle 5 to move toward the middle of the adjustment groove 2. When the device is picked up, the L-shaped plate 1 is brought into contact with the conveyor belt. The baffle 5 is located below the conveyor belt. When the handle 6 is turned, the baffle 5 gradually approaches the conveyor belt. The L-shaped plate 1 and the baffle 5 are brought into contact with the conveyor belt, and the device is installed on the upper conveyor belt.

[0043] After that, the upper and lower conveyor belts start to work normally, and the gravel transported on the upper conveyor belt falls on the lower conveyor belt. At this time, the limit frame 7 is located between the upper and lower conveyor belts. The exhaust fan inside the air outlet 8 is started to suck the stone powder on the gravel. The stone powder enters the guide port 9 through the air outlet 8 and falls into the storage chamber 14 through the groove formed between the rubber ring 10 and the storage chamber 14 for collection. When one storage chamber 14 is full, the start motor 29 continues to drive the feed box 13 to rotate, so that the adjacent inclined block 17 and the fixed rod 11 contact and open another storage chamber 14 for storage. When the fixed rod 11 leaves the full storage chamber 14 and returns to the point where the dust collection work is not required, it is only necessary to displace the inclined block 17 and the fixed rod 11 to ensure that the storage chamber 14 is in a sealed state to prevent the stone powder from flowing out, and the absorbed stone powder is in a dry state and can be used directly without drying again. After the work is completed, the rubber plug 25 is removed from the discharge port 24 to collect the stone powder inside the storage chamber 14.
