[0002] A concrete mixing plant is a combined device for centralized mixing of concrete, also known as a concrete prefabrication yard. Due to its high degree of mechanization and automation, its productivity is very high, and it can ensure the quality of concrete and save cement. It is commonly used in large and medium-sized water conservancy, electric power, bridge and other projects with large concrete engineering quantities, long construction periods and concentrated construction sites. With the development of municipal construction, the mixing plant that adopts centralized mixing and provides commercial concrete has great advantages, so it has developed rapidly, and has created conditions for promoting concrete pumping construction and realizing the combined operation of mixing, conveying and pouring machinery. In the existing concrete mixing plant, the mixing raw materials are input into the mixing cavity of the mixer through the feed inlet. Since there is a certain distance between the conveying equipment and the feed inlet, a large amount of dust will be generated when the mixing raw materials fall from the conveying equipment, which not only affects the health of the staff, but also pollutes the surrounding environment.

[0023] This specific embodiment is a dust removal structure for a concrete mixing plant, and its structural schematic diagram is as shown in Figure 1 and includes a top plate 4, a dust removal box 2 and a drive mechanism 3. The top plate 4 is located above the dust removal box 2 and the two are spaced apart. The drive mechanism 3 is arranged between the top plate 4 and the dust removal box 2. A transfer pipe 7 is installed on the upper surface of the dust removal box 2; a moving groove 6 is horizontally opened at the bottom end surface of the top plate 4, a drive lead screw 5 is horizontally and rotatably installed inside the moving groove 6, and a drive motor 1 is fixedly installed on the side wall of the top plate 4. The drive motor 1 is fixedly connected to the drive lead screw 5;

[0024] Referring to Figure 2 , the drive mechanism 3 includes a connecting rod 13, a lifting rod 10, and a support rod 9. The support rod 9 is slidably connected to the lifting rod 10, and the connecting rod 13 is fixedly installed at the upper end of the side wall of the lifting rod 10.

[0025] Referring to Figure 3 , an air outlet 15 connected to the transfer pipe 7 is opened inside the upper part of the dust removal box 2, and an air inlet 16 is opened at the bottom end surface of the dust removal box 2.

[0026] Referring to Figure 2 , Figure 4, there are two groups of support rods 9 symmetrically arranged. A fixing frame 8 is fixedly connected between the two groups of support rods 9, and the fixing frame 8 is fixed on the upper surface of the dust removal box 2. A lifting groove 17 is vertically opened on the surface of the lifting rod 10 facing the support rod 9. A connecting block 18 protrudes and is connected to the surface of the support rod 9 facing the lifting rod 10. A moving ring 14 is fixedly installed above the connecting rod 13. The moving ring 14 is embedded in the moving groove 6 and is threadedly connected to the driving lead screw 5. One end of the connecting block 18 passing through the lifting groove 17 is fixedly connected to a driving block 19, and the driving block 19 slides vertically along the surface of the lifting rod 10. Two fixing blocks 11 are fixedly connected to the outer wall of the lifting rod 10. A screw rod is rotatably installed between the two fixing blocks 11. A rotating motor 12 is fixedly installed on the upper surface of the fixing block 11, and the rotating motor 12 is connected to the screw rod. The driving block 19 is threadedly connected to the screw rod, and the screw rod vertically threadedly passes through the driving block 19.

[0027] Working principle: When in use, first hoist the top plate 4 above the raw material conveyor belt of the mixing plant. When the raw materials start to be fed, the rotating motor 12 is started. The rotating motor 12 drives the screw rod to rotate. The driving block 19 threadedly connected to the screw rod moves vertically along the surface of the lifting rod 10. The driving block 19 drives the support rod 9 to move synchronously through the connecting block 18. Then the driving rod is forced to descend, driving the fixing frame 8 to descend synchronously. The dust removal box 2 fixedly connected to the fixing frame 8 is forced to descend and gradually approaches the raw material conveying position. When dust is generated during raw material conveying, it is adsorbed through the air inlet 16 at the bottom of the dust removal box 2 and discharged through the air outlet 15 by the transmission pipe 7. One end of the transmission pipe 7 away from the dust removal box 2 is connected to a dust collector. By continuously approaching the dust source by the dust removal box 2, the adsorption quality of dust can be effectively improved and the dust removal efficiency can be increased;

[0028] During the dust removal process, the dust removal box 2 can also be driven to reciprocate horizontally, so as to further increase the dust adsorption range. The driving motor 1 is started to drive the driving lead screw 5 to rotate forward and backward. The moving ring 14 threadedly connected to the driving lead screw 5 then moves horizontally, driving the dust removal box 2 to move.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
