Description

Technical Field

[0001] This utility model relates to the field of concrete additive conveying technology, and in particular to a concrete additive conveying device. Background Technology

[0002] In the field of modern construction engineering and concrete product manufacturing, concrete additives play an indispensable role as key materials for improving concrete performance. Concrete additives refer to chemical or mineral materials added during the concrete mixing process to improve the workability, strength, durability, or other specific properties of concrete. They are diverse and include water-reducing agents, accelerators, retarders, air-entraining agents, etc. Different types of additives need to be accurately measured and delivered to the mixing system according to production needs.

[0003] To achieve efficient and stable delivery of concrete additives, various conveying devices have been developed in the industry, among which spiral tube conveyors and flexible auger spiral conveyors are two commonly used types. Spiral tube conveyors are rigid conveying devices; their core structure consists of spiral blades fixed within a rigid straight pipe. Driven by a motor, the spiral blades rotate, utilizing the friction and thrust between the blades and the material to achieve continuous delivery of the additives. This conveying method offers advantages such as simple structure, high conveying efficiency, and good sealing, and is widely used in short-distance, straight-line conveying scenarios between adjacent processing equipment, meeting the basic needs of short-distance material transfer.

[0004] However, in actual production workshop layouts, the placement of processing equipment is often limited by space, process flow, or other facilities. There are often other equipment rooms or functional areas between two pieces of equipment that need to convey additives. Because spiral tube conveyors use a rigid straight pipe design, their installation path is limited by the rigidity of the pipe and cannot be flexibly adjusted. They cannot cross intermediate equipment rooms or avoid obstacles, which greatly limits their application in complex workshop layouts.

[0005] In contrast, the flexible auger screw conveyor offers significantly improved layout flexibility thanks to its flexible pipe structure. Its pipes are made of bendable materials, allowing it to adapt to path bends and bypass obstacles or be arranged along non-linear paths, demonstrating adaptability in scenarios with large equipment spacing or spatial constraints. However, this type of equipment also has significant technical drawbacks: the friction between the flexible pipe and the screw blades is relatively intense, leading to rapid wear of both the pipe and blades. This not only requires frequent maintenance and replacement to ensure conveying stability but also risks contaminating additives with wear debris, affecting the quality of concrete products. Furthermore, from its initial design perspective, the flexible auger screw conveyor is more geared towards portable, temporary conveying needs. Its structural strength and durability are insufficient to meet the long-term, continuous conveying requirements of fixed production lines. Compared to screw tube conveyors, it is more prone to failure in fixed locations, increasing production maintenance costs and downtime risks.

[0006] In summary, existing concrete additive conveying devices all suffer from difficulties in balancing layout flexibility and long-term stability when facing fixed conveying needs in complex workshop layouts. There is an urgent need for a conveying solution that can adapt to conveying scenarios between non-adjacent equipment and combines layout flexibility with durability. Utility Model Content

[0027] Example 1

[0028] Please refer to the attached document. Figures 1-2This application provides a concrete additive conveying device, including a vertical pipe 1, a horizontal pipe 2, an inclined pipe 3, and a drive mechanism 4. The vertical pipe 1 is connected to the horizontal pipe 2 through the inclined pipe 3. Both the vertical pipe 1 and the horizontal pipe 2 are equipped with a spiral conveying shaft 5. The spiral conveying shaft 5 is equipped with a first bevel gear 6. The drive mechanism 4 includes a motor 7, a transmission shaft 8, and a second bevel gear 9. The end of the transmission shaft 8 is equipped with the second bevel gear 9. The first bevel gear 6 meshes with the second bevel gear 9. The motor 7 drives the spiral conveying shaft 5 to rotate. When the motor 7 rotates, it drives the conveying shaft to rotate. The spiral conveying shaft 5 is equipped with the first bevel gear 6. The first bevel gear 6, the second bevel gear 9, and the transmission shaft 8 constitute a transmission system. When the spiral conveying shaft 5 rotates, it drives the other spiral conveying shaft 5 to rotate through the transmission system. Since both the vertical pipe 1 and the horizontal pipe 2 are equipped with spiral conveying shafts 5, when the spiral conveying shafts 5 rotate, they push the concrete additives in the vertical pipe 1 and the horizontal pipe 2 to move, thereby completing the conveying of the concrete additives. This utility model includes a horizontal pipe 2 and a vertical pipe 1, enabling horizontal and vertical conveying. The conveying pipes can be installed close to the edges of equipment and cavities in the factory, avoiding the need for inclined conveying pipes. In situations with limited factory space, the concrete additive processing equipment can be placed close together, and the vertical pipe 1 can be fixed in the empty space between two adjacent pieces of equipment to achieve concrete additive conveying, effectively utilizing factory space.

[0029] Specifically, the drive shaft 8 includes a front half-shaft 10 and a rear half-shaft 11, which are connected by a universal joint 12. Both the front half-shaft 10 and the rear half-shaft 11 are equipped with a second bevel gear 9. The vertical tube 1 and the horizontal tube 2 are both fixed on a flat plate 13, which are rotatably connected to each other, with the axis of rotation of the two flat plates 13 passing through the center of the universal joint 12. When one second bevel gear 9 rotates, it drives the other second bevel gear 9 to rotate via the front half-shaft 10, the rear half-shaft 11, and the universal joint 12. The vertical tube 1 and the horizontal tube 2 are fixed on the flat plate 13, and the two flat plates 13 are rotatably connected to each other. The axis of rotation between the flat plates 13 passes through the center of the universal joint 12. When the vertical tube 1 and the horizontal tube 2 drive the flat plate 13 to rotate, the included angle between the front half-shaft 10 and the rear half-shaft 11 changes, and the transmission continues even after the change. During installation, this utility model allows for an angle of 0 to 15 degrees between the vertical axis and the vertical plane, and also allows for an angle of 0 to 15 degrees between the horizontal tube 2 and the horizontal plane, which facilitates installation and operation. In scenarios with limited space, the angles of the horizontal tube 2 and the vertical tube 1 can be adjusted.

[0030] Specifically, the inclined tube 3 is a metal tube that can be bent and deformed. The inclined tube 3 is bent at a certain angle to adapt to the angle changes of the vertical tube 1 and the horizontal tube 2. After being bent at a certain angle, concrete additives can still pass through the inclined tube 3.

[0031] Specifically, the plate 13 is provided with a bearing seat 14, and the front half shaft 10 and the rear half shaft 11 are rotatably connected to different bearing seats 14. The bearing seats 14 stabilize the front half shaft 10 and the rear half shaft 11, and ensure stable meshing of the first bevel gear 6 and the second bevel gear 9 when the plate 13 rotates relative to each other.

[0032] Specifically, the plate 13 is provided with a fixing hoop 15, and the horizontal pipe 2 and the vertical pipe 1 are fixed to the plate 13 by the fixing hoop 15. The fixing hoop 15 stabilizes the horizontal pipe 2 and the vertical pipe 1, improving the stability of the conveying pipe.

[0033] Specifically, the plate 13 is provided with mounting holes 16. The plate 13 is installed and fixed through the mounting holes 16, for example, by passing an installation tool such as a fixing screw through the mounting holes 16 and then tightening it to fix the plate 13.

[0034] Specifically, the screw conveyor shaft 5 is provided with a driven tooth 17, and the motor 7 is provided with a driving tooth 18. The driving tooth 18 meshes with the driven tooth 17, and the motor 7 is fixed on the plate 13. When the motor 7 rotates, it drives the driving tooth 18 to rotate. The driving tooth 18 meshes with the driven tooth 17, thereby driving the driven tooth 17 and the screw conveyor shaft 5 to rotate, realizing the conveying of concrete additives.

[0035] Specifically, both the driving gear 18 and the driven gear 17 are spur gears. Through the transmission via spur gears, the motor 7 can stably drive the screw conveyor shaft 5 to rotate when it is working.

[0036] Example 2

[0037] Please refer to the attached document. Figure 3The difference between this embodiment and Embodiment 1 is that both the vertical pipe 1 and the horizontal pipe 2 are splicing pipes 19. Each splicing pipe 19 includes a first pipe 20, a second pipe 21, and a threaded connector 22. The second pipe 21 has a threaded connector 22, which connects to the first pipe 20. The spiral conveying shaft 5 is a splicing shaft 23, which includes a first spiral shaft 24 and a second spiral shaft 25. The first spiral shaft 24 has a square plug 26, and the second spiral shaft 25 has a square slot 27 that mates with the square plug 26. The first spiral shaft 24 is rotatably connected to the first pipe 20, and the second spiral shaft 25 is rotatably connected to the second pipe 21. The splicing pipe 19 can be disassembled into two parts for separate installation. During transport, it is not necessary to move the entire conveying device, reducing the weight of separate transport and facilitating installation and handling. The second pipe 21 is fixedly connected to the threaded connector 22, which has an internal thread, while the first pipe 20 has an external thread. The threaded connector 22 engages with the thread of the first pipe 20, thereby connecting the second pipe 21 and the first pipe 20. During the connection of the first pipe 20 and the second pipe 21, the square plug 26 is aligned with the square slot 27. The first pipe 20 and the second pipe 21 are connected by a first spiral shaft 24 and a second spiral shaft 25, completing the connection. When the first spiral shaft 24 rotates, it drives the second spiral shaft 25 to rotate.

[0038] Specifically, it also includes a clamp 28, which is used to fix the second pipe 21. Depending on the installation environment, the clamp 28 or other fixing tools are selected to fix the second pipe 21.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
