Description

Technical Field

[0001] This invention relates to the field of green building construction technology, specifically to a method for prefabricating green building precast concrete components. Background Technology

[0002] In contrast, traditional cast-in-place concrete requires on-site formwork, pouring, and curing. Precast concrete components are widely used in construction, transportation, water conservancy, and other fields, playing a vital role in the national economy. The use of precast components significantly reduces on-site work, dust pollution, and noise pollution, making precast construction sites more environmentally friendly.

[0003] Precast component processing involves preparing and proportioning raw materials, then adding them to a mixer for thorough mixing. After uniform mixing, the concrete slurry is injected into the mold equipment. Following injection, a vibrator is used to agitate and remove air bubbles from the concrete, ensuring the uniformity and density of the finished precast concrete components. However, in existing concrete mixers, the concrete slurry cannot be completely removed, leaving a large amount of residual slurry inside, resulting in material waste. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, when the concrete slurry is discharged, the drive gear rotates. The rotation of the drive gear interacts with the toothed plate, thereby driving the mixing drum to gradually move upward. The concrete slurry in the upward-moving mixing drum automatically falls into the mold. The upward movement of the mixing drum causes the mixing drum and the movable base to move away from each other, driving the connecting shaft to rotate, causing the movable base to flip. This causes the spherical seat of the movable base to rotate upward, while the upper end of the movable shaft rotates downward and enters the precast mold. After the movable base flips, the rotation of the mixing shaft stirs and vibrates the concrete slurry in the mold, eliminating air bubbles in the concrete. At the same time, the mixing drum and mixing rod are completely detached and exposed. During the process of eliminating air bubbles on the mixing shaft, the residual concrete slurry on the mixing rod and the movable base will gradually fall into the mold. The mixing rod is completely exposed outside the mixing drum, which facilitates the thorough cleaning of the concrete slurry on it. Meanwhile, the residual concrete on the inner wall of the mixing drum falls into the spherical seat under the action of the scraper and automatically slides from the spherical seat into the mold. This facilitates the thorough pouring of concrete from both the mixing drum and the mixing rod, avoiding the problem of residual concrete slurry inside the mixer, which is in line with the concepts of energy saving, consumption reduction, and green environmental protection.

[0019] 2. In this invention, the transmission component drives the stirring shaft to rotate. The rotation of the stirring shaft drives multiple sets of stirring rods to rotate through the mounting plate. The stirring rods rotate to stir the raw materials in the mixing drum. At the same time, during the stirring process, the transmission component can continuously drive the connecting plate to move up and down, thereby driving the rotating stirring rods to move up and down, so that the raw materials in the mixing drum can come into more thorough and uniform contact with the stirring rods, thus making the concrete slurry in the mixing drum more uniformly mixed.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-8 This invention provides a technical solution: a method for prefabricating green building precast concrete components, including a mixing device, the method comprising the following steps:

[0033] Step 1: Pour the raw materials into the upper part of the mixing equipment for metering;

[0034] Step 2: The metered raw materials fall into the bottom of the mixing equipment for stirring and mixing;

[0035] Step 3: The mixed concrete slurry falls from the bottom of the mixing equipment into the precast component molding mold.

[0036] The mixing equipment in steps one, two, and three includes a mixing drum 1. A metering cylinder 3 is fixedly installed on the upper end of the mixing drum 1. A movable base 2 is provided at the lower end of the metering cylinder 3. A spherical seat 14 is fixedly installed on the lower surface of the movable base 2. Driving devices are provided on both sides of the movable base 2. The driving devices can drive the movable base 2 and the mixing drum 1 to move away from each other. A stirring shaft 18 is rotatably installed on the upper surface of the movable base 2. Multiple mounting rings 22 are slidably connected to the stirring shaft 18. Multiple stirring rods 19 are fixedly installed on the outer surface of the mounting rings 22. A connecting plate 20 is fixedly installed on each mounting ring 22. A fixed gear 38 is fixedly installed at the lower end of the stirring shaft 18. A transmission assembly is provided between the fixed gear 38 and the lower end of the connecting plate 20. The transmission assembly can drive the connecting plate 20 to move up and down continuously while driving the stirring shaft 18 to rotate continuously. A scraper 17 is provided between the metering cylinder 3 and the mixing drum 1. The scraper 17 is attached to the inner wall of the mixing drum 1.

[0037] During operation, raw materials are sequentially added into the metering cylinder 3 from the top (the movable plate 4 is in a horizontal state; the pressure sensor on the movable plate 4 measures the amount of raw materials added based on the raw material pressure; once the set raw material amount is reached, the injection stops, and then the upper movable rod 13 rotates to make the movable plate 4 rotate vertically, thus causing the raw materials in the metering cylinder 3 to fall into the mixing drum 1). After a certain amount of raw materials is measured by the metering cylinder 3, it falls into the mixing drum 1. After all the raw materials are measured and fall into the mixing drum 1, the transmission component drives the mixing shaft 18 to rotate. The rotation of the mixing shaft 18 drives multiple sets of mixing rods 19 to rotate through the mounting plate 27. The rotation of the mixing rods 19 stirs the raw materials in the mixing drum 1. At the same time, during the stirring process, the transmission component can continuously drive the connecting plate 20 to move up and down, thereby driving the rotating mixing rods 19 to move up and down, so that the raw materials in the mixing drum 1 can come into more thorough and uniform contact with the mixing rods 19, thus making the concrete slurry in the mixing drum 1 more uniformly mixed.

[0038] In this invention, the transmission component drives the stirring shaft 18 to rotate. The rotation of the stirring shaft 18 drives multiple sets of stirring rods 19 to rotate via the mounting plate 27. The stirring rods 19 rotate to stir the raw materials in the mixing drum 1. At the same time, during the stirring process, the transmission component can continuously drive the connecting plate 20 to move up and down, thereby driving the rotating stirring rods 19 to move up and down, so that the raw materials in the mixing drum 1 can come into more thorough and uniform contact with the stirring rods 19, thereby making the concrete slurry in the mixing drum 1 more uniformly mixed.

[0039] As a further embodiment of the present invention, the transmission assembly includes a mounting plate 27, which is fixedly mounted on the upper surface of the movable base 2. A drive bevel gear 37 is rotatably mounted on the mounting plate 27, and an intermediate gear 30 is fixedly mounted on the lower end of the drive bevel gear 37. A drive rod 35 is rotatably mounted on one end of the mounting plate 27 near the stirring shaft 18, and a driven bevel gear 36 is fixedly mounted on one end of the drive rod 35 near the mounting plate 27. The driven bevel gear 36 meshes with the drive bevel gear 37. An actuating element 23 is fixedly mounted on one end of the drive rod 35 away from the driven bevel gear 36. A limiting groove 25 is formed on the actuating element 23. A positioning seat 42 is rotatably mounted on the lower end of the connecting plate 20, and an upper connecting rod 24 is fixedly mounted on the positioning seat 42. The upper connecting rod 24 is embedded in the limiting groove 25.

[0040] During operation, the intermediate gear 30 continuously rotates in both directions, driving the upper bevel gear to rotate (the built-in motor drives the drive gear 39 to rotate, the drive gear 39 drives the drive wheel 40 to rotate, the drive wheel 40 drives the driven wheel 29 to rotate in the forward direction via the transmission belt 41, the driven wheel 29 drives the first half-axle gear 33 to rotate, the drive gear 39 drives the driven gear 28 meshing with it to rotate in the reverse direction, the driven gear 28 drives the second half-axle gear 34 to rotate in the reverse direction, and the first half-axle gear 33 and the second half-axle gear 34 alternately mesh with the intermediate gear 30). This causes the intermediate gear 30 to rotate continuously (in both directions). The rotation of the upper bevel gear drives the driven bevel gear 36, which meshes with it, to rotate. The rotation of the driven bevel gear 36 drives the drive rod 35 to rotate. The rotation of the drive rod 35 drives the actuating element 23 to rotate. The rotation of the actuating element 23 pulls the upper connecting rod 24 through the limiting groove 25, thereby causing the upper connecting rod 24 to move up and down. The downward movement of the upper connecting rod 24 causes the positioning seat 42 to move up and down. The upward and downward movement of the positioning seat 42 causes the connecting plate 20 to move up and down. The upward and downward movement of the connecting plate 20 causes the stirring rod 19 to move up and down during the rotation.

[0041] In this invention, a single built-in motor drives the stirring rod 19 to rotate and move up and down simultaneously, reducing the number of drive sources and allowing a single drive source to drive multiple motions at the same time, thereby improving energy utilization.

[0042] As a further embodiment of the present invention, a drive gear 39 is rotatably mounted on the upper surface of the movable base 2 corresponding to the lower part of the mounting plate 27. A drive wheel 40 is fixedly mounted on the upper surface of the drive gear 39. A driven gear 28 is rotatably mounted on the upper surface of the movable base 2 opposite to one side of the mounting plate 27. The driven gear 28 meshes with the drive gear 39. A driven wheel 29 is rotatably mounted on the upper surface of the movable base 2 at a position symmetrical to the driven gear 28 with the mounting plate 27 as the axis of symmetry. A transmission belt 41 is sleeved on the driven wheel 29 and the drive wheel 40.

[0043] As a further embodiment of the present invention, a second half-axle gear 34 is fixedly mounted on the upper surface of the driven gear 28, a first half-axle gear 33 is fixedly mounted on the upper surface of the driven wheel 29, and an intermediate gear 30 is rotatably disposed between the first half-axle gear 33 and the second half-axle gear 34, with the teeth of the first half-axle gear 33 and the second half-axle gear 34 alternately meshing with the intermediate gear 30.

[0044] As a further embodiment of the present invention, an upper movable rod 13 is rotatably installed inside the measuring cylinder 3, and a movable plate 4 is fixedly installed on the upper movable rod 13. A connecting ring 16 is rotatably installed between the measuring cylinder 3 and the stirring cylinder 1. The lower surface of the connecting ring 16 is fixedly connected to the scraper 17. A protruding rod 21 is fixedly installed on the inner wall of the connecting ring 16. An upper motor 32 is fixedly installed at the lower end of the measuring cylinder 3. An upper gear 31 is fixedly installed at the output end of the upper motor 32. An upper gear ring 15 is fixedly installed on the upper surface of the connecting ring 16, and the upper gear ring 15 meshes with the upper gear 31.

[0045] During operation, when the concrete slurry is being discharged, the precast mold is placed below the movable base 2. An external motor drives the drive gear 10 to rotate. The drive gear 10 interacts with the toothed plate 8, thereby driving the mixing drum 1 to gradually move upward. The concrete slurry inside the upward-moving mixing drum 1 automatically falls into the mold. The upward movement of the mixing drum 1 causes the mixing drum 1 and the movable base 2 to move away from each other. When the lower end of the mixing drum 1 moves to the upper end of the mixing shaft 18, the drive connecting shaft 12 rotates, causing the movable base 2 to flip. This causes the spherical seat 14 of the movable base 2 to rotate upward, while the upper end of the movable shaft rotates downward and enters the precast mold. After the movable base 2 flips, the mixing shaft 18 rotates to stir and vibrate the concrete slurry inside the mold, eliminating air bubbles in the concrete. At the same time, the mixing drum 1 and the mixing rod... When the mixing rod 19 is completely detached and exposed, during the process of eliminating air bubbles on the mixing shaft 18, the residual concrete slurry on the mixing rod 19 and the movable base 2 will gradually detach and fall into the mold. The mixing rod 19 is completely exposed outside the mixing drum 1, which facilitates the thorough cleaning of the concrete slurry on it. At the same time, the residual concrete on the inner wall of the mixing drum 1 falls into the spherical seat 14 under the action of the scraper 17 (the upper motor 32 drives the upper gear 31 to rotate, the upper gear 31 rotates and drives the upper gear ring 15 to rotate, the upper gear ring 15 rotates and drives the connecting ring 16 to rotate, the connecting ring 16 rotates and drives the scraper 17 to rotate, and the inner wall of the mixing drum 1 is cleaned by the scraper 17). It then automatically slides from the spherical seat 14 into the mold, which facilitates the thorough pouring out of the concrete from both the mixing drum 1 and the mixing rod 19, avoiding the problem of residual concrete slurry inside the mixer.

[0046] In this invention, when the concrete slurry is discharged, the drive gear 10 rotates, interacting with the toothed plate 8, thereby driving the mixing drum 1 to gradually move upward. The concrete slurry inside the upward-moving mixing drum 1 automatically falls into the mold. The upward movement of the mixing drum 1 causes the mixing drum 1 and the movable base 2 to move away from each other, driving the connecting shaft 12 to rotate, causing the movable base 2 to flip. This causes the spherical seat 14 of the movable base 2 to rotate upward, while the upper end of the movable shaft rotates downward and enters the precast mold. After the movable base 2 flips, the mixing shaft 18 rotates to stir and vibrate the concrete slurry inside the mold, eliminating the mixing and vibration of the slurry inside the mold. During the process of eliminating air bubbles in the concrete, the mixing drum 1 and the mixing rod 19 are completely detached and exposed. As the mixing shaft 18 eliminates air bubbles, the residual concrete slurry on the mixing rod 19 and the movable base 2 gradually falls into the mold. The mixing rod 19 is completely exposed outside the mixing drum 1, making it easy to thoroughly clean the concrete slurry on it. At the same time, the residual concrete on the inner wall of the mixing drum 1 falls onto the spherical seat 14 under the action of the scraper 17, and automatically slides from the spherical seat 14 into the mold. This facilitates the thorough pouring out of the concrete from both the mixing drum 1 and the mixing rod 19, avoiding the problem of residual concrete slurry inside the mixer.

[0047] As a further embodiment of the present invention, the driving device includes an upper fixed frame 6, which is disposed above the stirring cylinder 1. The metering cylinder 3 is slidably connected to the upper fixed frame 6. Lower connecting frames 7 are fixedly installed on both sides of the upper fixed frame 6. A toothed plate 8 is fixedly installed at the lower end of the lower connecting frame 7. A connecting shaft 12 is rotatably installed at the lower end of the toothed plate 8. A movable base 2 is fixedly installed between the connecting shafts 12. A rotating motor 11 is fixedly installed at the lower end of the toothed plate 8. The output end of the rotating motor 11 is fixedly connected to the connecting shaft 12.
