[0034] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0035] The present utility model provides an environmental protection dust collection system for a concrete mixing plant as shown in Figures 1 to 4 the figure, which includes an equipment box body 1. A lifting mechanism is arranged on the upper side of the equipment box body 1. The lifting mechanism includes a first fixing plate 11, a rewinding shaft 12, a servo motor 13, a support rod 14, a support plate 16, a second fixing plate 17, a transmission shaft 18 and a steel cable 19. There are two groups of support rods 14. The two groups of support rods 14 are fixedly connected to the upper surface of the equipment box body 1. The support plate 16 is fixedly connected to the upper ends of the two groups of support rods 14. Multiple groups of fixed frames 110 are fixedly connected to the sides of the two groups of support rods 14. Positioning grooves 15 are formed on the front, rear, left and right surfaces of the two groups of support rods 14. An installation bracket 2 is slidably connected between the two groups of support rods 14. Multiple groups of positioning rollers 21 are rotatably connected to the left and right sides of the installation bracket 2. The positioning rollers 21 are respectively slidably connected to the front and rear positioning grooves 15. A dust suction box body 3 is fixedly installed on the upper surface of the installation bracket 2.

[0036] Among them, the support rod 14 is fixedly connected to the side surface of the powder bin through the fixed frame 110. During the use process, the installation bracket 2 is driven to lift by the lifting mechanism, and then the dust suction box body 3 is driven to lift. During the overhaul and maintenance process, the dust suction box body 3 is lowered to the ground, which is convenient for overhauling, maintaining and cleaning the equipment. During the use process, the dust suction box body 3 is lifted to the top of the powder bin, reducing the length of the equipment pipeline and improving the dust suction effect and suction efficiency.

[0037] Refer toFigure 1 and Figure 3 , the first fixing plate 11 is fixedly connected to the inner wall of the equipment box body 1. Both ends of the cable take-up reel 12 are rotatably connected to two groups of first fixing plates 11. The servo motor 13 is fixedly installed at the right position inside the equipment box body 1. The output end of the servo motor 13 is fixedly connected to the right end of the cable take-up reel 12. The second fixing plate 17 is fixed on the upper surface of the support plate 16. Both ends of the transmission shaft 18 are respectively rotatably connected to two groups of second fixing plates 17. The lower ends of the steel cables 19 are fixedly connected to both ends of the cable take-up reel 12. The upper ends of the steel cables 19 bypass both ends of the transmission shaft 18 and are fixedly connected to the upper ends of the mounting brackets 2.

[0038] Specifically, during the process of equipment maintenance and cleaning, the output end of the servo motor 13 drives the cable take-up reel 12 to rotate clockwise. The cable take-up reel 12 releases the steel cables 19 upward, causing the upper ends of the steel cables 19 to extend downward. At this time, the mounting bracket 2 is moved downward, and at the same time, multiple positioning rollers 21 roll downward inside the positioning grooves 15 to position the mounting bracket 2. At the same time, the mounting bracket 2 drives the dust suction box body 3 to move downward, thereby facilitating the cleaning and maintenance of the inside of the dust suction box body 3.

[0039] In addition, during use, the output end of the servo motor 13 drives the cable take-up reel 12 to rotate counterclockwise to wind up the lower ends of the steel cables 19, thereby driving the mounting bracket 2 to slide upward between the two support rods 14 and moving the dust suction box body 3 to the upper end of the powder bin. At this time, the dust suction box body 3 sucks the scattered dust inside the powder bin through a shorter equipment pipeline.

[0040] Refer to Figures 4 to 6 , an electric cylinder 22 is fixedly installed at the upper end of the mounting bracket 2. A suction pipeline 31 is fixedly connected to the upper end of the dust suction box body 3. A sealing sleeve 34 is slidably connected to the rear end of the suction pipeline 31. A transmission rod 38 is fixedly connected to the side surface of the sealing sleeve 34. The end of the transmission rod 38 away from the sealing sleeve 34 is fixedly connected to the telescopic rod in the electric cylinder 22. A first fixing ring 32 is fixedly connected to the surface of the suction pipeline 31 near the rear end. A first rubber pad 33 is fixedly connected to the front side surface of the first fixing ring 32. A sealing pad 35 is fixedly connected to the front side inner wall of the sealing sleeve 34. A second fixing ring 36 is fixedly connected to the side inner wall of the sealing sleeve 34. A second rubber pad 37 is fixedly connected to the rear surface of the second fixing ring 36. A transmission pipeline 4 is arranged at the rear end of the suction pipeline 31. The transmission pipeline 4 is fixedly connected to the upper end of the powder bin. A third fixing ring 41 is fixedly connected to the surface of the transmission pipeline 4 near the front end. A third rubber pad 42 is fixedly connected to the front side surface of the third fixing ring 41.

[0041] Meanwhile, after moving the dust suction box body 3 to the upper end, the suction pipe 31 will be flush with the transmission pipe 4. At this time, the telescopic rod in the electric cylinder 22 drives the sealing sleeve 34 to slide backward through the transmission rod 38, so that the sealing sleeve 34 is sleeved between the suction pipe 31 and the transmission pipe 4. At this time, the sealing gasket 35 abuts tightly against the first rubber gasket 33 to seal the connection between the sealing sleeve 34 and the suction pipe 31, and the surface of the second rubber gasket 37 abuts tightly against the surface of the third rubber gasket 42 to seal the connection between the sealing sleeve 34 and the transmission pipe 4, realizing the automatic connection of the suction pipe 31 and the transmission pipe 4.

[0042] The working principle of the present utility model: The lifting mechanism drives the mounting bracket 2 to rise and fall, and then drives the dust suction box body 3 to rise and fall. During the overhaul and maintenance process, the dust suction box body 3 is lowered to the ground, which is convenient for overhauling, maintaining and cleaning the equipment. During the use process, the dust suction box body 3 is raised to the top of the powder bin, reducing the length of the equipment pipeline, improving the dust suction effect and suction efficiency. At the same time, the telescopic rod in the electric cylinder 22 drives the sealing sleeve 34 to slide backward through the transmission rod 38 to automatically connect the suction pipe 31 and the transmission pipe 4.

[0043] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
