[0044] The present utility model will be further described in combination with the following embodiments.

[0045] Embodiment 1.

[0046] As Figures 1 - 4As shown in the figure, a dust-proof and leakage-proof device for a screening machine includes a screening machine body 1, on which a sealing cover 2 is installed. An inlet 3 and a collection port 4 are provided on the sealing cover 2. The collection port 4 is connected to a dust collection mechanism 5 through a pipeline. A motor bracket 6 is installed on the top of the sealing cover 2. The motor bracket 6 is located between the inlet 3 and the collection port 4, and a servo motor 7 is installed on the motor bracket 6.

[0047] The inlet 3 is used to add materials to be screened, and the collection port 4 is used for dust collection. The servo motor 7 is a common existing technology and will not be elaborated here.

[0048] As Figures 1 - 4 shown in the figure, the output shaft of the servo motor 7 is fixedly connected to a transmission component 8. The transmission component 8 is connected to a first transmission shaft 9 and a second transmission shaft 10. Both the first transmission shaft 9 and the second transmission shaft 10 pass through the sealing cover 2. A first half gear 11 is fixedly installed at the bottom end of the first transmission shaft 9, and a second half gear 12 is fixedly installed at the bottom end of the second transmission shaft 10. A sealing partition 13 is slidably connected to the sealing cover 2, and transmission racks 14 are installed on both sides of the sealing partition 13. The first half gear 11 and the second half gear 12 are respectively engaged with the transmission racks 14.

[0049] By driving the first transmission shaft 9 and the second transmission shaft 10 through the servo motor 7, the first half gear 11 and the second half gear 12 are driven to rotate synchronously. The two half gears drive the sealing partition 13 to move reciprocally. When adding materials, the sealing partition 13 is made to block the collection port 4 to prevent material leakage. When starting the screening, the sealing partition 13 is made to block the inlet 3 to prevent dust from flying, and at the same time, the excess miscellaneous dust is collected and processed.

[0050] As Figure 1 shown in the figure, the dust collection mechanism 5 includes a collection box 51, which is installed on the side of the screening machine body 1. A suction fan 52 is connected to the side of the collection box 51 through a pipeline. A load-bearing slide rail 53 is fixedly installed inside the collection box 51. A cloth bag clamp 54 is slidably connected to the load-bearing slide rail 53. One end of the cloth bag clamp 54 extends to the outside of the collection box 51, and a dust collection cloth bag 55 is clamped and fixed inside the cloth bag clamp 54.

[0051] Start the suction fan 52 to suck the miscellaneous dust into the collection box 51, and filter the dust through the dust collection cloth bag 55. The load-bearing slide rail 53 is slidably connected to the cloth bag clamp 54, so that the staff can pull out the cloth bag clamp 54 to replace or further process the dust collection cloth bag 55.

[0052] As Figure 1As shown, the cloth bag splint 54 includes an upper splint 541 and a lower splint 542. One end of the upper splint 541 is hinged to the lower splint 542. A limiting groove 543 is provided at the other end of the upper splint 541. A limiting slider 544 is movably installed on the side of the collection box 51. The upper splint 541 and the lower splint 542 clamp and fix the dust collection cloth bag 55. The staff can change the state of the cloth bag splint 54 by moving the limiting slider 544, which is convenient for clamping the cloth bag splint 54 or pulling it out.

[0053] As Figure 1 shown, a funnel-shaped channel 15 is installed at the bottom of the collection box 51. The four top surfaces of the funnel-shaped channel 15 are fixedly connected to the inner wall of the collection box 51. The bottom of the funnel-shaped channel 15 is connected to the suction fan 52 through a pipeline. The funnel-shaped channel 15 facilitates the operation of the suction fan 52.

[0054] As Figures 1 - 4 shown, the transmission assembly 8 includes a first transmission wheel 81, a second transmission wheel 82, and a transmission belt 83. The first transmission wheel 81 is fixedly installed on the output shaft of the servo motor 7. The servo motor 7 is fixedly connected to the first transmission shaft 9. The second transmission wheel 82 is fixedly installed on the second transmission shaft 10. The first transmission wheel 81 and the second transmission wheel 82 are connected by the transmission belt 83.

[0055] This enables a transmission relationship to be formed among the servo motor 7, the first transmission wheel 81, the second transmission wheel 82, the transmission belt 83, the first transmission shaft 9, and the second transmission shaft 10.

[0056] As Figures 1 - 4 shown, two sliding grooves 16 are provided on the sealing cover 2. A plurality of sliding blocks 17 are provided at the top of the sealing partition 13. The sliding blocks 17 are slidably connected to the sliding grooves 16.

[0057] In the present utility model, the servo motor 7 drives the first half gear 11 and the second half gear 12 to rotate synchronously. The two half gears drive the sealing partition 13 to reciprocate, so that the sealing partition 13 blocks the collection port 4 or the feeding port 3, avoiding material leakage or preventing dust from flying. At the same time, the excess dust is sucked into the collection box 51 and filtered by the dust collection cloth bag 55. The bearing slide rail 53 is slidably connected to the cloth bag splint 54, enabling the staff to pull out the cloth bag splint 54 to replace the dust collection cloth bag 55. The sealing performance at the equipment interface can be flexibly adjusted through the sealing partition 13 to avoid dust leakage. At the same time, the installation of the dust collection mechanism 5 facilitates the collection and treatment of dust, improving the working environment quality and ensuring that the staff will not be affected by dust in terms of health.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
