Abstract
Description

It has the characteristics of high strength, good durability and convenient construction. It is widely used in construction, infrastructure, roads, bridges and other projects. The concrete production process requires mixing cement and other powders with raw materials such as aggregates and water in a certain proportion, and the production process is usually carried out continuously, so it is necessary to be able to accurately control the delivery amount and flow rate of the powder.
[0003] An existing segmented powder conveying equipment for concrete production is used in which a horizontal pouring barrel is connected to the bottom of the discharge barrel.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a segmented powder conveying equipment for concrete production, comprising a conveyor belt 1, support frames 2 are fixedly connected to both sides of the upper part of the conveyor belt 1, and a mixing tank 3 is fixedly connected to the opposite sides of the two support frames 2, a motor 5 is fixedly connected to the upper part of the mixing tank 3, a rotating shaft 6 is fixedly connected to the output end of the motor 5, and a stirring assembly is fixedly connected to the outside of the rotating shaft 6, and the stirring assembly includes a disc 7, the disc 7 is fixedly connected to the outside of the rotating shaft 6, and a stirring blade 8 is fixedly connected to the outside of the disc 7, a ring 9 is fixedly connected to the outside of the rotating shaft 6, and a fixed rod 10 is fixedly connected to the outside of the ring 9, and a scraper 11 is fixedly connected to the other end of the fixed rod 10, a feed pipe 4 is fixedly connected to the upper part of the mixing tank 3, and a plurality of scrapers 11 are slidably connected to the inner wall of the mixing tank 3.
[0024] Start the motor 5, and its output end starts to drive the shaft 6 to rotate. As the shaft 6 rotates, the disc 7 also starts to rotate, and the rotation of the disc 7 further drives the rotation of the stirring blade 8. The rotation of the stirring blade 8 continuously mixes and stirs the powder to ensure that the powder can be fully and evenly mixed. The rotation of the shaft 6 also drives the rotation of the ring 9, and the rotation of the ring 9 further drives the rotation of the fixed rod 10, and the rotation of the fixed rod 10 finally drives the rotation of the scraper 11, and the scraper 11 can completely scrape off the powder adhered to the inner wall of the mixing tank 3.
[0025] Reference Figure 1 and Figure 2A fixing plate 15 is fixedly connected to the right part of the mixing tank 3, a hydraulic cylinder 16 is fixedly connected to the bottom of the fixing plate 15, a mounting plate 18 is fixedly connected to the output end of the hydraulic cylinder 16, a baffle 14 is fixedly connected to the bottom of the mounting plate 18, a discharge hopper 13 is fixedly connected to the right part of the mixing tank 3, a conveying box 19 is arranged on the upper part of the conveyor belt 1, a discharge port 12 is opened on one side of the interior of the mixing tank 3, the discharge hopper 13 is arranged on the right part of the discharge port 12, the baffle 14 is slidably connected to the inside of the discharge hopper 13, springs 17 are fixedly connected to both sides of the bottom of the fixing plate 15, and the other end of the spring 17 is fixedly connected to the upper part of the mounting plate 18.
[0026] When the stirred powders are ready to be discharged, they flow out smoothly through the discharge port 12. At this time, the hydraulic cylinder 16 is started, and the output end of the hydraulic cylinder 16 is closely connected with the mounting plate 18. When the hydraulic cylinder 16 is started, the mounting plate 18 is driven to move. In this process, the mounting plate 18 stretches the spring 17, and the spring 17, with its unique elastic characteristics, provides necessary support and buffering for the movement of the mounting plate 18. As the mounting plate 18 moves, it drives the baffle 14 to rise, and the baffle 14 moves up and down inside the discharge hopper 13. This action not only ensures the smooth discharge of the powder, but also creates conditions for the segmented transportation of the powder. The powder inside the mixing tank 3 is discharged outward through the discharge port 12 and directly enters the interior of the conveying box 19. Subsequently, through the synergistic effect of the conveyor belt 1 and the conveying box 19, the powder is transported to different positions in segments.
[0027] Working principle: first, pour the powder into the mixing tank 3 through the feed pipe 4, start the motor 5, the output end of the motor 5 drives the shaft 6 to rotate, the shaft 6 drives the disc 7 to rotate, the disc 7 drives the stirring blade 8 to rotate, the stirring blade 8 rotates to stir the powder, the shaft 6 rotates and drives the ring 9 to rotate, the ring 9 drives the fixed rod 10 to rotate, the fixed rod 10 drives the scraper 11 to rotate, so that the scraper 11 scrapes off the powder adhered to the inner wall of the mixing tank 3, thereby effectively cleaning the inner wall of the mixing tank 3, effectively reducing the powder residue, ensuring the uniform mixing of the powder during the mixing process, avoiding uneven mixing due to residues and affecting the quality of concrete, and improving Production efficiency is improved to prevent cross contamination. The mixed powder is discharged through the discharge port 12, and the hydraulic cylinder 16 is started. The output end of the hydraulic cylinder 16 drives the mounting plate 18 to move. When the mounting plate 18 moves, the spring 17 is stretched. Under the action of the spring 17, the mounting plate 18 drives the baffle 14 to move upward, so that the baffle 14 moves up and down inside the discharge hopper 13. The powder inside the mixing tank 3 can be discharged to the inside of the conveying box 19 through the discharge port 12. The powder is conveyed in sections through the conveyor belt 1 and the conveying box 19, thereby achieving precise control of the amount of powder added, ensuring that the amount of powder required at each stage in the concrete production process meets the expectations, and ensuring the stability and consistency of product quality.
