[0026] As Figures 1 to 4 shown, the specific embodiment of the present utility model provides a dust-proof conveying device for concrete aggregates. The conveying device includes a base 1 for support and transportation. The conveying device includes a conveying mechanism and a dust-proof mechanism. The conveying mechanism includes a lifting box 2 fixedly installed on the upper end of the base 1. A lifting plate 3 is arranged on the left side of the lifting box 2. A conveying box 4 is arranged on the left side of the lifting plate 3. A servo motor 7 is arranged on the upper end of the base 1. The output shaft of the servo motor 7 penetrates through the lifting box 2 and is fixedly connected with a first bevel gear 8. The first bevel gear 8 meshes with a second bevel gear 9. The second bevel gear 9 is fixedly installed on a first lead screw 10. The first lead screw 10 is rotatably connected inside the lifting box 2. An active plate 11 is threadedly driven on the outer side of the first lead screw 10. The upper end of the active plate 11 is fixedly connected with a push rod 12. The other end of the push rod 12 penetrates through the lifting box 2 and is fixedly connected with the lifting plate 3. Specifically, as Figure 2 and Figure 4As shown in the figure, a slider 16 is fixedly connected to the right side of the conveying box 4. The slider 16 is clamped in a slide rail 17, and the slide rail 17 is opened on the side surface of the lifting plate 3. One end of a cord 13 is fixedly connected to the inner bottom end of the lifting box 2. The other end of the cord 13 penetrates through the movable plate 11 and the push rod 12 and is fixedly connected to the conveying box 4. The first pulley 14 and the second pulley 15 are attached to the outer side of the cord 13. Both the first pulley 14 and the second pulley 15 are fixedly connected to the lifting plate 3. During use, the slide rail 17 drives the first lead screw 10 to rotate through the first bevel gear 8 and the second bevel gear 9. Then, since the first lead screw 10 is threadedly connected to the movable plate 11, the first lead screw 10 drives the movable plate 11 to move up and down. Then, the movable plate 11 drives the conveying box 4 to move up and down through the push rod 12 and the cord 13. Finally, since one end of the cord 13 is fixedly connected to the inner bottom end of the lifting box 2 and the other end of the cord 13 is fixedly connected to the conveying box 4, and the cord 13 is attached to the first pulley 14 and the second pulley 15, the conveying box 4 slides outside the lifting plate 3, and the position of the conveying box 4 is restricted by the slider 16 and the slide rail 17, so that the conveying box 4 stably moves on one side of the lifting plate 3, which is beneficial to driving the lifting plate 3 to move up and down, facilitating the conveying of the conveying box 4 on the left side of the lifting plate 3 to a high place. And through the arrangement of the cord 13, the conveying box 4 can be driven to move up and down doubly, which not only greatly increases the moving range of the conveying box 4, facilitates the conveying of the conveying box 4 from a low place to a high place, but also doubles the lifting speed of the conveying box 4, improving the conveying efficiency.

[0027] Specifically, as Figure 2 and Figure 3As shown in the figure, the dust-proof mechanism includes a feed hopper 5 arranged at the upper end of the conveying box 4. A first baffle 21 is inserted at the bottom end of the feed hopper 5. A discharge hopper 6 is arranged on the left side of the conveying box 4. A second baffle 25 is inserted at the upper end of the discharge hopper 6. The periphery of the bottom end of the feed hopper 5 is inclined towards the port of the conveying box 4. The periphery of the bottom end of the conveying box 4 is inclined towards the discharge hopper 6. An activity cavity 18 is opened inside the conveying box 4. One end of a second lead screw 19 is rotatably connected to the inner side of the activity cavity 18. The other end of the second lead screw 19 penetrates through the conveying box 4 and is fixedly connected with a first knob 20. The outer side of the second lead screw 19 is threadedly connected with the first baffle 21. One end of a third lead screw 22 is rotatably connected to the upper end of the discharge hopper 6. The other end of the third lead screw 22 penetrates through the vertical plate 23 and is fixedly connected with a second knob 24. The vertical plate 23 is fixedly connected to the conveying box 4. The outer side of the third lead screw 22 is threadedly connected with the second baffle 25. During use, the concrete aggregate is gathered at the port through the feed hopper 5 and then sent into the conveying box 4. Then, the first knob 20 is rotated. The first knob 20 drives the first baffle 21 to move to the lower end of the feed hopper 5 to close the port of the conveying box 4. Finally, the second knob 24 is rotated. The second knob 24 drives the second baffle 25 to lift and lower through the third lead screw 22 and the vertical plate 23, so that the second baffle 25 is separated from the discharge hopper 6, and the concrete aggregate in the conveying box 4 flows out from the discharge hopper 6. It is beneficial to quickly gather the concrete aggregate through the feed hopper 5 and send it into the conveying box 4, which can not only avoid the scattering of the aggregate, but also reduce the port area and the dust generation space of the conveying box 4. The port of the conveying box 4 can be conveniently closed by the first baffle 21 to avoid the dust and scattering of the concrete aggregate during transportation. And the discharge speed of the concrete aggregate in the conveying box 4 can be controlled by the second baffle 25, which is convenient for taking the concrete aggregate in the conveying box 4.

[0028] Working principle: During use, the slide rail 17 drives the first lead screw 10 to rotate through the first bevel gear 8 and the second bevel gear 9. Then, because the first lead screw 10 is threadedly connected with the movable plate 11, the first lead screw 10 drives the movable plate 11 to lift and lower. Then, the movable plate 11 drives the conveying box 4 to lift and lower through the push rod 12 and the rope 13. Finally, because one end of the rope 13 is fixedly connected to the bottom end inside the lifting box 2 and the other end of the rope 13 is fixedly connected to the conveying box 4, and the rope 13 is attached to the first pulley 14 and the second pulley 15, the conveying box 4 slides outside the lifting plate 3, and the position of the conveying box 4 is restricted by the slider 16 and the slide rail 17, so that the conveying box 4 stably moves on one side of the lifting plate 3. It is beneficial to drive the lifting plate 3 to lift and lower, which is convenient for conveying the conveying box 4 on the left side of the lifting plate 3 to a high place. And the setting of the rope 13 can drive the conveying box 4 to lift and lower doubly, which not only greatly increases the moving range of the conveying box 4 and is convenient for conveying the conveying box 4 from a low place to a high place, but also doubles the lifting speed of the conveying box 4 and improves the conveying efficiency.

[0029] The concrete aggregate is gathered to the port through the feed hopper 5 and then fed into the conveying box 4. Then, the first knob 20 is rotated. The first knob 20 drives the first baffle 21 to move to the lower end of the feed hopper 5 to close the port of the conveying box 4. Finally, the second knob 24 is rotated. The second knob 24 drives the second baffle 25 to move up and down through the third lead screw 22 and the vertical plate 23, so that the second baffle 25 is separated from the discharge hopper 6, and thus the concrete aggregate in the conveying box 4 flows out from the discharge hopper 6. This is beneficial to quickly gather the concrete aggregate through the feed hopper 5 and feed it into the conveying box 4, which can not only avoid the scattering of the aggregate, but also reduce the port area and the dust generation space of the conveying box 4. The port of the conveying box 4 can be easily closed by the first baffle 21 to avoid the dust and scattering of the concrete aggregate during transportation. Moreover, the discharge speed of the concrete aggregate in the conveying box 4 can be controlled by the second baffle 25, which is convenient for taking the concrete aggregate in the conveying box 4.
