Description

Technical Field

[0001] This invention relates to the field of water-stabilized mixing plant technology, specifically to a mill-type unloading anti-segregation device for a water-stabilized mixing plant. Background Technology

[0002] A water-stabilized mixing plant is a large-scale machine specifically used in industrial construction for mixing water-stabilized materials. Water-stabilized materials generally include cement, fly ash, graded crushed stone, and stabilized soil materials. Water-stabilized mixing plants are used for the construction of base stabilization soil for high-grade highways, urban roads, squares, and airports.

[0003] After being mixed by twin-shaft mixers, the mixture falls onto a conveyor belt, which then transports it to the finished product silo. As the mixture falls from the top of the conveyor belt, it undergoes a projectile motion, causing large stones in the mixture to deviate from its trajectory and land slightly further away in the finished product silo than the main mixture. Furthermore, the landing point of the mixture in the finished product silo remains constant, resulting in the mixture accumulating in a mountain-like pattern within the silo. The stones at the edges of the mixture slide towards the sides of the silo under the influence of gravity, while the center consists entirely of fine particles, leading to the concentration of large stones and resulting in aggregate segregation.

[0004] Based on this, the present invention designs a mill-type unloading anti-segregation device for water-stabilized stations to solve the above problems. Summary of the Invention

[0021] Please see Figure 1-5 The present invention provides a technical solution: a mill-type unloading anti-segregation device for a water-stabilized station, comprising a conveyor belt 1 and a finished product bin 2. A baffle frame 3 is provided on the top of the finished product bin 2. A first rotating shaft 4 is rotatably connected to the baffle frame 3. Multiple blades 5 are welded on the first rotating shaft 4. The blades 5 are located below the top of the conveyor belt 1. A first driving mechanism for driving the blades 5 to rotate is also provided on the baffle frame 3.

[0022] Protective plates 6 are fixedly connected to both ends of the blade 5; an arc-shaped baffle 7 is provided inside the baffle frame 3, and the inner wall of the arc-shaped baffle 7 is completely in contact with the protective plate 6; three first discharge ports 8 are symmetrically arranged at the bottom end of the arc-shaped baffle 7; a sealing plate 9 is slidably connected to the outer wall of the arc-shaped baffle 7; an arc-shaped spring 10 for resetting is fixedly connected to the sealing plate 9; the sealing plate 9 is used to block the first discharge ports 8, and a second discharge port 11 that can dock with the first discharge ports 8 is provided on the sealing plate 9; a second driving mechanism for driving its movement is provided on the side of the sealing plate 9.

[0023] like Figure 1 As shown, during operation, the conveyor belt 1 moves the mixture upwards. When the mixture is thrown from the top of the conveyor belt 1, it falls into the area between two adjacent blades 5. The protective plate 6 can prevent the mixture from falling out from both ends. It should be noted that in this embodiment, there are 6 blades 5. The first drive mechanism drives the first rotating shaft 4 to rotate 60° at regular intervals. Figure 2 As shown, every 60° rotation of the first rotating shaft 4 creates a cavity (the area formed between two adjacent blades 5) that rotates to the area below the conveyor 1 to receive the mixture; during the rotation of the blades 5, the arc-shaped baffle 7 can shield the mixture in the cavity, preventing it from falling directly when the blades 5 rotate to a certain angle; as Figure 2 , Figure 3 As shown, when the cavities below the horizontal blade 5 are all filled with the mixture, the second drive mechanism will drive the sealing plate 9 to rotate clockwise by a certain angle. After the sealing plate 9 rotates, the second discharge port 11 will connect with the first discharge port 8, and then the mixture in the three cavities will fall from the three first discharge ports 8 respectively. The mixture in the lower left cavity will slide down the left inclined blade 5 to the left side of the finished product bin 2; the mixture in the lower middle cavity will fall vertically to the middle of the finished product bin 2; the mixture in the lower right cavity will slide down the right inclined blade 5 to the right side of the finished product bin 2. The mixture in the three lower cavities will fall to the left, middle, and right sides of the finished product bin respectively, which can prevent the mixture from falling from one position and accumulating into a small mountain. The mixture can be piled up flat in the finished product bin. Large stones will not scatter around the finished product silo. This invention, through the arrangement of blades 5, arc-shaped baffles 7, a first discharge port, a sealing plate 9, and a second discharge port 11, ensures that the mixture delivered to the top of the silo falls into the cavity between adjacent blades 5, allowing for further mixing within the cavity and preventing segregation during the fall. When the cavities containing the mixture rotate to their lowest positions, the mixture can slide from three different locations into the finished product silo, effectively preventing the mixture from accumulating in one location and thus preventing stones from scattering to the sides and causing segregation. Furthermore, this invention features six blades 5 and six corresponding cavities, grouped in sets of three, allowing the first rotating shaft 4 and blades 5 to operate cyclically.

[0024] As a further embodiment of the present invention, a second rotating shaft 12 is provided between each two adjacent blades 5, a stirring rod 13 is provided on each of the second rotating shafts 12, a first sprocket 14 is fixedly connected to each of the second rotating shafts 12, and a chain 15 is driven and connected to multiple first sprockets 14; a first motor 16 is driven and connected to one of the second rotating shafts 12.

[0025] like Figures 3-4 As shown, during actual operation, the first motor 16 can drive one of the second rotating shafts 12 to rotate, which in turn drives the first sprocket 14 on it to rotate. The first sprocket 14 drives the other first sprockets 14 to rotate synchronously via the chain 15. The first sprocket 14 drives the second rotating shaft 12 to rotate, which in turn drives the stirring rod 13 to rotate. The second rotating shaft 12 and the stirring rod 13 can stir the mixture in the cavity between two adjacent blades 5, which can better prevent the mixture from segregating.

[0026] As a further embodiment of the present invention, the second driving mechanism includes a first gear 17 and an incomplete gear 18; two first gears 17 are provided, the two first gears 17 are symmetrically arranged about the first rotating shaft 4, and are fixedly connected to two of the second rotating shafts 12; the incomplete gear 18 is rotatably connected to the baffle 3, the incomplete gear 18 can mesh with the first gear 17, a winding roller 19 is fixedly connected to the rotating shaft of the incomplete gear 18, and a traction rope 20 is wound on the winding roller 19; one end of the traction rope 20 is fixedly connected to the winding roller 19, and the other end is fixedly connected to the sealing plate 9.

[0027] like Figure 4 As shown, during specific operation, when all three cavities at the bottom are filled with the mixture, the first gear 17 moves to the position where it meshes with the incomplete gear 18. The first gear 17 drives the incomplete gear 18 to rotate, which in turn drives the winding roller 19 to rotate. The winding roller 19 winds up the traction rope 20, which in turn drives the sealing plate 9 to rotate clockwise around the arc-shaped baffle until the first discharge port 8 and the second discharge port 11 are aligned. Through the setting of the second drive mechanism, the sealing plate 9 will only rotate when the first gear 17 rotates to the position where it meshes with the incomplete gear 18, which can ensure that the mixture will not fall out of the discharge port when the blade is rotating.

[0028] As a further embodiment of the present invention, two partition plates 21 are installed on the side wall of the finished product warehouse 2.

[0029] like Figure 2 As shown, during actual operation, the two partition plates 21 divide the internal space of the finished product warehouse into three areas: left, middle, and right. The mixture in the three cavities will fall into the three areas respectively. When the mixture in the finished product warehouse is loaded onto the truck, after the mixture in the three areas is reduced, the stones in the mixture in each independent area will not slide outwards, which can prevent the mixture from segregating during loading.

[0030] As a further embodiment of the present invention, the first driving mechanism includes a second motor 22, which is mounted on the side wall of the baffle frame 3, and the output shaft of the second motor 22 is fixedly connected to the first rotating shaft 4.

[0031] like Figure 5 As shown, in actual operation, the second motor 22 can drive the first rotating shaft 4 to rotate.

[0032] Working principle: The conveyor belt 1 drives the mixture upward. When the mixture is thrown from the top of the conveyor belt 1, it falls into the area between two adjacent blades 5. The protective plate 6 can prevent the mixture from falling out from both ends. It should be noted that in this embodiment, there are 6 blades 5. The first drive mechanism drives the first rotating shaft 4 to rotate 60° at regular intervals. Figure 2 As shown, every 60° rotation of the first rotating shaft 4 creates a cavity (the area formed between two adjacent blades 5) that rotates to the area below the conveyor 1 to receive the mixture; during the rotation of the blades 5, the arc-shaped baffle 7 can shield the mixture in the cavity, preventing it from falling directly when the blades 5 rotate to a certain angle; as Figure 2 , Figure 3 As shown, when the cavities below the horizontal blade 5 are all filled with the mixture, the second drive mechanism will drive the sealing plate 9 to rotate clockwise by a certain angle. After the sealing plate 9 rotates, the second discharge port 11 will connect with the first discharge port 8, and then the mixture in the three cavities will fall from the three first discharge ports 8 respectively. The mixture in the lower left cavity will slide down the left inclined blade 5 to the left side of the finished product bin 2; the mixture in the lower middle cavity will fall vertically to the middle of the finished product bin 2; the mixture in the lower right cavity will slide down the right inclined blade 5 to the right side of the finished product bin 2. The mixture in the three lower cavities will fall to the left, middle, and right sides of the finished product bin respectively, which can prevent the mixture from falling from one position and accumulating into a small mountain. The mixture can be piled up flat in the finished product bin. Large stones will not scatter around the finished product silo. This invention, through the arrangement of blades 5, arc-shaped baffles 7, a first discharge port, a sealing plate 9, and a second discharge port 11, ensures that the mixture delivered to the top of the silo falls into the cavity between adjacent blades 5, allowing for further mixing within the cavity and preventing segregation during the fall. When the cavities containing the mixture rotate to their lowest positions, the mixture can slide from three different locations into the finished product silo, effectively preventing the mixture from accumulating in one location and thus preventing stones from scattering to the sides and causing segregation. Furthermore, this invention features six blades 5 and six corresponding cavities, grouped in sets of three, allowing the first rotating shaft 4 and blades 5 to operate cyclically.
