Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete preparation technology, specifically to a spray dust suppression device for concrete preparation. Background Technology
[0002] The dust suppression spraying system for concrete preparation is an essential piece of equipment for creating a green production environment. It consists of a corrosion-resistant piping system, fine spray nozzles, and an intelligent control unit. The piping is cleverly positioned around dust-prone areas such as mixers, material storage areas, and conveyor belts, ensuring comprehensive coverage. The spray nozzles disperse water into a fine mist, which quickly combines with airborne dust, increasing its weight and causing it to settle. The intelligent control unit automatically adjusts the spray intensity and duration based on feedback from dust concentration sensors. When dust levels exceed the standard, the spray volume is immediately increased; when the concentration decreases, the spray is promptly reduced. This effectively suppresses dust while avoiding water waste, helping concrete preparation operate efficiently and environmentally friendly.
[0003] A search revealed that Chinese patent CN221385722U discloses a spray dust suppression device for concrete preparation. The patent describes a method in which dust suppression water is pumped into a spray disc by a water pump, and the spray disc is rotated by a motor. Through the cooperation of a support rod, annular groove and slider, the spray disc rotates on the dust collection box, and the dust suppression water is rotated and thrown out, increasing the spray coverage area and improving the dust suppression effect. This technical solution effectively avoids the problems of small spray range and low dust suppression effect.
[0004] In this solution, although the spraying area can be increased by spraying a disc, the device can only spray at the same horizontal angle and cannot accurately spray concrete at different angles and heights, resulting in a significant reduction in dust suppression effect. To solve this technical problem, this utility model proposes a spray dust suppression device for concrete preparation. Utility Model Content

[0014] (III) Beneficial Effects
[0015] This utility model provides a spray dust suppression device for concrete preparation. It has the following beneficial effects:
[0016] (1) Start the electric push rod one, which drives the connecting plate to move up and down along the positioning rod to adjust the nozzle height. Then start the electric push rod two, which pushes the rack to move left and right on the connecting plate. The limiting plate limits it in the limiting groove. The rack drives the gear and the rotating column to rotate, so that the support frame rotates left and right to adjust the left and right angle of the nozzle.

Traditional equipment loses water directly after spraying and cannot be recycled. Through the cooperation of these components, water recycling is achieved, improving utilization rate, reducing cost, reducing water consumption, and ensuring continuous and efficient spraying operations.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] Please see Figure 1-4 This utility model provides a technical solution:
[0025] Example 1: A dust suppression spraying device for concrete preparation includes a cart 1. A pair of electric push rods 3 are fixedly connected to the top of the cart 1. A connecting plate 4 is fixedly connected to the output end of the electric push rods 3. An electric push rod 5 is fixedly connected to the top of the connecting plate 4. A rack 6 is fixedly connected to the output end of the electric push rod 5. A rotating column 9 is rotatably connected inside the middle of the connecting plate 4. A gear 8 is fixedly connected to the outer wall of the rotating column 9, meshing with the rack 6. A support frame 11 is fixedly connected to the top of the rotating column 9. A motor 12 is fixedly connected to the outer wall of the other end of the support frame 11. A rotating shaft 13 is fixedly connected to the output end of the motor 12. A connecting arm 14 is fixedly connected to the outer wall, and a support plate 15 is provided at the other end of the connecting arm 14. Multiple nozzles 16 are provided inside the support plate 15. A pair of vertical plates 2 are fixedly connected to the top of the trolley 1. A positioning rod 17 is fixedly connected inside each vertical plate 2. The two ends of the connecting plate 4 are slidably connected to the outer walls of the positioning rods 17 on both sides. A limiting plate 7 is fixedly connected to the bottom of the rack 6. A limiting groove 10 is opened inside the connecting plate 4. The limiting plate 7 corresponds to the limiting groove 10. At the same time, the limiting plate 7 is slidably connected in the limiting groove 10. The support frame 11 is rotatably connected above the connecting plate 4. The connecting plate 4 is slidably connected between the two vertical plates 2.
[0026] During concrete preparation, the electric push rod 3 on top of the trolley 1 is activated first. Electric push rod 3 pushes the connecting plate 4 up and down along the positioning rod 17 inside the vertical plate 2, thereby adjusting the height of the nozzle 16. Then, electric push rod 5 on top of the connecting plate 4 is activated, pushing the rack 6 to move left and right on the connecting plate 4. The limiting plate 7 limits the movement of the rack 6 within the limiting groove 10, ensuring stable movement. As the rack 6 moves, it drives the gear 8 and the rotating column 9 to rotate. The rotating column 9 further drives the support frame 11 to rotate left and right, achieving left and right angle adjustment of the nozzle 16. The motor 12 is activated, driving the rotating shaft 13 to rotate, which in turn drives the connecting arm 14 to adjust its angle. Through the coordinated operation of these components, the nozzle 16 can be quickly adjusted in multiple directions and angles, improving the efficiency of dust suppression and other related work during concrete preparation.
[0027] Example 2: The difference between this example and Example 1 is that a water tank 18 is fixedly connected to the top of the cart 1, a water pump 19 is fixedly connected to the top of the water tank 18, a water outlet hose 20 is fixedly connected to the output end of the water pump 19, the other end of the water outlet hose 20 is fixedly connected to the support plate 15, and the water outlet hose 20 corresponds to the nozzle 16. A water collection tank 21 is fixedly connected to the top of the cart 1, the water collection tank 21 is located below the nozzle 16, and a diversion plate 22 is fixedly connected inside the water collection tank 21. A water inlet pipe 23 is provided on one side of the water collection tank 21. A water pump 24 is fixedly connected to the lower outer wall of the water tank 18, and the other end of the water inlet pipe 23 is fixedly connected to the output end of the water pump 24.
[0028] First, the water pump 19 at the top of the water storage tank 18 is started. After the water pump 19 starts working, it draws water out of the water storage tank 18, and the water is transported to the nozzle 16 inside the support plate 15 through the outlet hose 20. The nozzle 16 then begins spraying to suppress dust. During the spraying process, some water droplets fall into the water collection tank 21, and the guide plate 22 directs this water to the side of the inlet pipe 23. At this time, the second water pump 24 is started, which pumps the water in the water collection tank 21 back into the water storage tank 18, realizing the recycling of water resources. These components work together to not only improve the utilization rate of water resources, but also improve the overall efficiency of dust suppression operations.
[0029] Working principle: When workers need to suppress dust during concrete preparation, firstly, water pump 19 on top of water tank 18 is started. Water pump 19 draws water from inside water tank 18 and delivers it through outlet hose 20 to nozzle 16 inside support plate 15 for dust suppression. During spraying, some water droplets fall into water collection tank 21 and are guided by diversion plate 22 to the side of inlet pipe 23. Then, water pump 24 is started to return this water to water tank 18 for continued use. This coordination improves work efficiency. During concrete preparation, the electric push rod 3 on top of the platform trolley 1 is activated, causing connecting plate 4 to move up and down. When the connecting plate 4 moves, it is limited to the positioning rod 17 inside the vertical plate 2. When the connecting plate 4 is raised or lowered, the height of the nozzle 16 can be adjusted. In conjunction with the activation of the electric push rod 2 5 at the top of the connecting plate 4, the rack 6 is pushed to move left and right on the connecting plate 4 under the action of the electric push rod 2 5, and is limited in the limiting groove 10 by the limiting plate 7. When the rack 6 moves, it will drive the gear 8 and the rotating column 9 to rotate. When the rotating column 9 rotates, it will drive the support frame 11 to rotate left and right, thereby adjusting the nozzle 16 left and right. At this time, the motor 12 is activated to drive the rotating shaft 13 to rotate, thereby driving the connecting arm 14 to adjust the angle. Through their cooperation, the nozzle 16 can be quickly adjusted in multiple directions and angles, thereby improving work efficiency.
