Description

Technical Field

[0001] This utility model relates to the field of concrete diversion technology, specifically to a concrete pouring diversion device. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials, granular aggregates, water, and, when necessary, admixtures and additives in a certain proportion, uniformly stirring, compacting, and curing. Concrete pouring refers to the process of pouring concrete into a mold until it is plasticized. In civil engineering, it involves using concrete and other materials to form a predetermined shape.

[0003] A search revealed that CN115977395A discloses a concrete pouring guide device for civil construction and its usage method. The device includes a guiding mechanism for guiding concrete to the pouring point, an tilting mechanism for tilting or leveling the guiding mechanism, and a intercepting mechanism for intercepting excess concrete in the guiding mechanism after it is tilted. By setting a blocking plate, the device can promptly intercept residual concrete inside the guiding plate after pouring the required amount of concrete, avoiding waste caused by continuous concrete pouring. Furthermore, the device is equipped with a first inclined block, a first sliding plate, a first return spring, a first slider, a second inclined block, and a trigger switch, which triggers an electric telescopic rod to retract after intercepting the concrete, changing the guiding plate from an inclined state to a horizontal state, preventing excessive concrete from overflowing and further avoiding concrete waste. However, when adjusting the discharge position of the guide channel, manual handling is required to adjust the angle of the guide channel, which is not only labor-intensive but also easily results in concrete splashing onto clothing, making it inconvenient to use. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a concrete pouring guide device, which aims to solve the problem that in the existing technology, when it is necessary to adjust the discharge position of the guide channel, it is necessary to manually handle the material to adjust the angle of the guide channel, which not only wastes manpower, but also easily splashes concrete onto clothes.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A concrete pouring guide device includes a base, a support plate slidably connected to the top of the base, a limiting seat fixedly connected to the outside of the support plate, a first worm gear rotatably connected inside the limiting seat, a first sector worm wheel meshing with the top of the first worm gear, a linkage shaft fixedly connected inside the first sector worm wheel, a mounting seat rotatably connected to the outside of the linkage shaft and located on the top of the support plate, a swing rod fixedly connected to the outside of the linkage shaft, a mounting ear fixedly connected to one end of the top of the support plate, a second worm gear rotatably connected inside the mounting ear, a connecting rod rotatably connected to the outside of the second worm gear, and a guide plate provided on the top of the connecting rod.

[0007] As a preferred embodiment of this utility model, a square frame is fixedly connected to the bottom of the connecting rod, and an auxiliary wheel is rotatably connected to one end of the swing rod, with the auxiliary wheel slidably connected inside the square frame.

[0008] As a preferred embodiment of this utility model, a fixed base is fixedly connected to the top of the connecting rod, a drive rod is rotatably connected inside the fixed base, an mounting block is fixedly connected to the outside of the drive rod, and the guide plate is fixedly connected to the drive rod through the mounting block.

[0009] As a preferred embodiment of this utility model, a second sector worm gear is fixedly connected to one end of the drive rod, the second sector worm gear is meshed with a second worm, and a first motor is fixedly connected to the outside of the mounting ear, the output end of the first motor is fixedly connected to the second worm.

[0010] As a preferred embodiment of this utility model, a second motor is fixedly connected to the outside of the limiting seat, the second motor is fixedly connected to one end of the first worm gear, a plate is fixedly connected between the bases, a sleeve is fixedly connected to the top of the plate, an extension rod is slidably connected inside the sleeve, and the extension rod is rotatably connected to the support plate.

[0011] As a preferred embodiment of this utility model, a third motor is fixedly connected to the bottom end of the inner side of the sleeve, and an installation sleeve is fixedly connected to the output end of the third motor. A limit groove is formed on the surface of the installation sleeve.

[0012] As a preferred embodiment of this utility model, a positioning post is fixedly connected to the bottom end of the extension rod. The positioning post extends to the outside of the limiting groove and is slidably connected to the limiting groove. The extension rod is slidably connected to the inside of the mounting sleeve. A fixing post is sleeved on the outside of the mounting sleeve. The fixing post is rotatably connected to the bottom end of the inner side of the sleeve. A spiral groove is opened inside the fixing post. The positioning post passes through the limiting groove and is slidably connected to the spiral groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the auxiliary wheel slides inside the square frame and lifts the connecting rod, thus tilting the guide plate to facilitate material guidance. When there is residual concrete inside the guide plate, the swing rod tilts it to a certain angle, causing the second worm and the second sector worm wheel to engage with each other. The drive rod rotates the guide plate, controlling the rotation direction of the first motor output, thus causing the guide plate to swing back and forth and shake off the residual concrete. This avoids the tedious manual handling and adjustment, saving manpower and preventing concrete from sticking to clothes during handling. It is convenient to adjust, easy to use, and saves time and effort.

[0015] 2. In this utility model, the third motor drives the mounting sleeve to rotate. At this time, the positioning post is squeezed by the limiting groove, causing the positioning post to slide inside the spiral groove. Then the extension rod will spiral up inside the mounting sleeve. As it gradually rises, the positioning post will slide to the top of the limiting groove, completing the fixing work after height adjustment. This achieves the height adjustment of the guide plate to adapt to different scenarios. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0023] A concrete pouring guide device includes a base 1, a support plate 2 slidably connected to the top of the base 1, a limiting seat 3 fixedly connected to the outside of the support plate 2, a first worm gear 4 rotatably connected inside the limiting seat 3, a first sector worm wheel 5 meshing with the top of the first worm gear 4, a linkage shaft 6 fixedly connected inside the first sector worm wheel 5, a mounting seat 7 rotatably connected to the outside of the linkage shaft 6 and located on the top of the support plate 2, a swing rod 8 fixedly connected to the outside of the linkage shaft 6, a mounting ear 9 fixedly connected to one end of the top of the support plate 2, a second worm gear 10 rotatably connected inside the mounting ear 9, and a connecting rod 11 rotatably connected to the outside of the second worm gear 10. A guide plate 12 is provided at the top. By placing the base 1 in the unloading area of ​​the cement tanker truck, the guide plate 12 is aligned with the unloading port of the cement tanker truck. Then, the first worm 4 is rotated, and then the first worm 4 meshes with the first sector worm wheel 5. At this time, the first sector worm wheel 5 rotates, and under the limiting action of the mounting seat 7, the linkage shaft 6 rotates with the first sector worm wheel 5. Then, it drives one end of the swing rod 8 to move along the outside of the linkage shaft 6, so that the swing rod 8 swings. Then, the connecting rod 11 is lifted. At the same time, the connecting rod 11 moves along the outside of the second worm 10. At this time, the guide plate 12 is in an inclined position.

[0024] Furthermore, in this embodiment, a square frame 13 is fixedly connected to the bottom of the connecting rod 11, and an auxiliary wheel 14 is rotatably connected to one end of the swing rod 8. The auxiliary wheel 14 is slidably connected inside the square frame 13. When the swing rod 8 is tilted, the auxiliary wheel 14 will slide inside the square frame 13 and lift the connecting rod 11.

[0025] Furthermore, in this embodiment, a fixed base is fixedly connected to the top of the connecting rod 11, a drive rod 15 is rotatably connected inside the fixed base, and an mounting block is fixedly connected to the outside of the drive rod 15. The guide plate 12 is fixedly connected to the drive rod 15 through the mounting block. A second sector worm gear 16 is fixedly connected to one end of the drive rod 15. The second sector worm gear 16 meshes with the second worm 10. A first motor 17 is fixedly connected to the outside of the mounting ear 9. The output end of the first motor 17 is fixedly connected to the second worm 10. The first motor 17 controls the second worm 10 to rotate, and the second motor 18 controls the first worm 10 to rotate. When there is residual concrete inside the guide plate 12, after tilting to a certain angle by the swing rod 8, the second worm 10 and the second sector worm gear 16 come into contact with each other. By rotating the second worm 10, the second sector worm gear 16 is driven to rotate, and then the drive rod 15 is driven to rotate. The rotation direction of the output end of the first motor 17 is controlled, so that the guide plate 12 swings back and forth to shake off the residual concrete.

[0026] Furthermore, in this embodiment, a second motor 18 is fixedly connected to the outside of the limiting seat 3. The second motor 18 is fixedly connected to one end of the first worm gear 4. A plate is fixedly connected between the bases 1. A sleeve 19 is fixedly connected to the top of the plate. An extension rod 20 is slidably connected inside the sleeve 19. The extension rod 20 is rotatably connected to the support plate 2. A third motor 21 is fixedly connected to the bottom end of the inner side of the sleeve 19. An mounting sleeve 22 is fixedly connected to the output end of the third motor 21. A limiting groove 23 is formed on the surface of the mounting sleeve 22. A positioning post 24 is fixedly connected to the bottom end of the extension rod 20. The positioning post 24 extends to the outside of the limiting groove 23 and is slidably connected to the limiting groove 23. The extension rod 20 is slidably connected to the mounting sleeve 22. Inside, a fixing post 25 is fitted on the outside of the mounting sleeve 22. The fixing post 25 is rotatably connected to the bottom end of the inner side of the sleeve 19. A spiral groove 26 is opened inside the fixing post 25. The positioning post 24 passes through the limiting groove 23 and is slidably connected to the spiral groove 26. By driving the third motor 21, the third motor 21 drives the mounting sleeve 22 to rotate. At this time, the positioning post 24 is squeezed by the limiting groove 23, so that the positioning post 24 slides inside the spiral groove 26. Then the extension rod 20 will spiral up inside the mounting sleeve 22. As it gradually rises, the positioning post 24 will slide to the top of the limiting groove 23, completing the fixing work after height adjustment. This realizes the height adjustment of the guide plate 12 to adapt to different scenarios.

[0027] In this embodiment, the specific implementation scenario is as follows: by moving the base 1 to a designated position, the guide plate 12 is positioned below the concrete discharge point, allowing the concrete to flow directly into the top of the guide plate 12. The second motor 18 controls the first worm gear 4 to rotate, and then the first worm gear 4 meshes with the first sector worm wheel 5. At this time, the first sector worm wheel 5 rotates, and under the limiting action of the mounting base 7, the linkage shaft 6 rotates along the first sector worm wheel 5, thereby driving one end of the swing rod 8 to move along the outside of the linkage shaft 6, causing the swing rod 8 to swing. The auxiliary wheel 14 slides inside the square frame 13 and lifts the connecting rod 11. The connecting rod 11 moves along the outside of the second worm gear 10, at which point the guide plate 12 is tilted, facilitating the guiding discharge. When the remaining part inside the guide plate 12 is mixed... During concrete pouring, after the swing rod 8 is tilted to a certain angle, the second worm gear 10 and the second sector worm wheel 16 come into contact with each other. By rotating the second worm gear 10, the second sector worm wheel 16 is driven to rotate, which in turn drives the drive rod 15 to rotate, controlling the rotation direction of the output end of the first motor 17, so that the guide plate 12 swings back and forth to shake off the remaining concrete. By driving the third motor 21, the third motor 21 drives the mounting sleeve 22 to rotate. At this time, the positioning post 24 is squeezed by the limiting groove 23, so that the positioning post 24 slides inside the spiral groove 26. Then the extension rod 20 spirals up inside the mounting sleeve 22. As it gradually rises, the positioning post 24 slides to the top of the limiting groove 23, completing the fixing work after height adjustment. This achieves the height adjustment of the guide plate 12 to adapt to different scenarios.
