Technical Field
[0001] This invention relates to the field of concrete construction technology, and in particular to a concrete pouring device. Background Technology
[0002] During road construction, concrete pouring is required, which necessitates the use of pouring equipment. Existing pouring equipment typically includes a material mixing mechanism, a material discharging mechanism, and other supporting mechanisms. The material mixing mechanism is used to temporarily store the concrete and continuously mix it to prevent adverse phenomena such as slurry heaving or setting, thus ensuring the quality of the concrete. Then, the material discharging mechanism discharges the concrete to the required location, completing the pouring construction.
[0003] The following defects exist in its use: the mixing effect of the material mixing mechanism is insufficient, and there is still a possibility that the concrete will solidify; the discharge mechanism is mostly set horizontally, and the discharge port is set at the rear end. The distance from the discharge of concrete from the material mixing mechanism to the discharge on the road surface is too long, which may cause the concrete to solidify. Therefore, improvements are needed. Summary of the Invention
[0004] To overcome the shortcomings of the prior art, the present invention provides a concrete pouring device that effectively solves the problem of concrete potentially hardening.
[0005] The technical solution to the technical problem is as follows: a concrete pouring device, including a base plate, a material bucket on the base plate, a mixing drum rotatably arranged inside the material bucket, a core cylinder fixed to the material bucket inside the mixing drum, a first auger on the inner side of the mixing drum in contact with the outer wall of the core cylinder, the core cylinder having a cavity inside, and the core cylinder connected to a discharge port located below the base plate. When the mixing drum rotates, the first auger pulls the concrete upward. A first through hole is opened at the upper end of the core cylinder, and a second through hole is opened above the mixing drum. The first through hole connects the interior of the core cylinder with the interior of the mixing drum, and the second through hole connects the interior of the mixing drum with the interior of the material bucket. A second auger in a horizontal direction is rotatably arranged on the outer side of the mixing drum. When the mixing drum rotates, it drives the second auger to rotate, pushing the concrete in the material bucket towards the mixing drum.

The control mechanism also includes a fixing plate located above the material barrel. The fixing plate is telescopically disposed on the top of the material barrel via a first hydraulic cylinder. The fixing plate is connected to the first baffle via a second connecting rod and to the second baffle via a third connecting rod. When the fixing plate rises, the first baffle is in contact with the inner wall of the core cylinder to block the first through hole, while the second baffle moves away from the inner wall of the mixing cylinder and opens the second through hole. When the fixing plate descends, the first baffle moves away from the core cylinder and opens the first through hole, while the second baffle is in contact with the inner wall of the mixing cylinder to block the second through hole.

[0023] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.
[0024] Depend on Figures 1 to 8 It is known that a concrete pouring device includes a base plate 1, a material bucket 2 is provided on the base plate 1, a material bucket 2 has a feed inlet 38 on its side, a mixing drum 3 is rotatably arranged inside the material bucket 2, a core cylinder 4 is fixed to the material bucket 2 inside the mixing drum 3, a first auger 5 is provided on the inner side of the mixing drum 3 and contacts the outer wall of the core cylinder 4, the core cylinder 4 is hollow inside, the core cylinder 4 is connected to a discharge port 6 located below the base plate 1, when the mixing drum 3 rotates, the first auger 5 drives the concrete upward, a first through hole 7 is opened at the upper end of the core cylinder 4, a second through hole 8 is opened above the mixing drum 3, the first through hole 7 connects the inside of the core cylinder 4 and the inside of the mixing drum 3, the second through hole 8 connects the inside of the mixing drum 3 and the inside of the material bucket 2, a second auger 9 is rotatably arranged on the outer side of the mixing drum 3, when the mixing drum 3 rotates, it drives the second auger 9 to rotate and push the concrete in the material bucket 2 toward the mixing drum 3.
[0025] In practical use, this invention Concrete is added into the bucket 2 through the inlet 38. The equipment is started, and the mixing drum 3 rotates, driving the second auger 9 to mix the concrete in the bucket 2. There is a gap between the bottom of the mixing drum 3 and the bottom of the bucket 2. The concrete enters the mixing drum 3 from the bottom and moves upward under the action of the first auger 5. When the pouring position is not reached, the first through hole 7 is closed and the second through hole 8 is opened. When the concrete moves upward to the position in the mixing drum 3, it falls back into the bucket 2 through the second through hole 8. The second auger 9 rotates on its own as it rotates with the mixing drum 3, which can push the concrete near the inner wall of the bucket 2 towards the mixing drum 3, reducing the impact of centrifugal force on the concrete and allowing more concrete to participate in the mixing. This prevents the concrete near the inner wall of the bucket 2 from stagnating and solidifying. When the pouring position is reached, the first through hole 7 opens and the second through hole 8 closes. The concrete enters the core cylinder 4 through the first through hole 7 and is discharged from the outlet 6, thus completing the pouring.
[0026] The first auger 5 inside the mixing drum 3 can move the concrete at the bottom of the bucket 2 upwards, preventing the concrete at the bottom from not participating in the mixing for a long time. At the same time, the second auger 9 can push the concrete on the outside inwards, increasing the mixing range and improving the mixing effect.
[0027] Multiple support wheels 10 are provided below the base plate 1. The support wheels 10 are mounted on the base plate 1 via guide posts 11. The support wheels 10 are equipped with screws 12 that are threadedly connected to the base plate 1. The screws 12 are driven by a first motor 13. The first motor 13 drives the screws 12 to rotate. The screws 12 are threadedly connected to the base plate 1. The rotation of the screws 12 causes the support wheels 10 to rise and fall below the base plate 1, thus adjusting the height. During pouring, the support wheels 10 located behind the discharge port 6 can be retracted to avoid damaging the poured concrete.
[0028] A connecting column 14 is provided on the bottom plate 1 at the end away from the material bucket 2. A connecting arm 15 is provided on the top of the connecting column 14. The connecting arm 15 is used to connect with the traction mechanism. After connecting the connecting arm 15 with the traction mechanism, the height of the support wheel 10 is adjusted so that the height of the bottom plate 1 is appropriate, which is conducive to concrete pouring.
[0029] A second motor 16 is installed at the top of the material barrel 2. The output shaft of the second motor 16 extends into the material barrel 2 and is equipped with a first gear 17. A first gear ring 18 that meshes with the first gear 17 is provided on the outer side of the upper end of the stirring drum 3, forming a structure in which the second motor 16 drives the stirring drum 3 to rotate. A rotating ring 19 is installed inside the material barrel 2. The rotating ring 19 is rotatably connected to the stirring drum 3. The rotating ring 19 is fixed to the inner wall of the material barrel 2 by multiple first connecting rods 20.
[0030] The mixing drum 3 rotates on the rotating ring 19, and the first auger 5 contacts the outer wall of the core cylinder 4 to stabilize the rotation of the mixing drum 3. The second motor 16 drives the mixing drum 3 to rotate stably inside the material bucket 2.
[0031] The upper end of the core cylinder 4 has a constricted structure, while the upper part of the mixing drum 3 has an open structure. When the concrete lifted by the first auger 5 reaches a high position, the inclined structure above the core cylinder 4 and the upper part of the mixing drum 3 makes it easier to transfer the concrete through the first through hole 7 or the second through hole 8.
[0032] A control mechanism is installed on the material barrel 2. The control mechanism includes a first baffle 21 installed inside the core cylinder 4 and a second baffle 22 installed between the core cylinder 4 and the mixing cylinder 3. The first baffle 21 is shaped to match the inner wall of the core cylinder 4, and the second baffle 22 is shaped to match the inner wall of the mixing cylinder 3. The control mechanism also includes a fixing plate 23 located above the material barrel 2. The fixing plate 23 is telescopically mounted on the top of the material barrel 2 via a first hydraulic cylinder 24. The fixing plate 23 is connected to the first baffle 21 via a second connecting rod 25, and to the second baffle 22 via a third connecting rod 26. When the fixing plate 23 rises, the first baffle 21 is in contact with the inner wall of the core cylinder 4, blocking the first through hole 7, while the second baffle 22 moves away from the inner wall of the mixing cylinder 3, opening the second through hole 8. When the fixing plate 23 falls, the first baffle 21 moves away from the core cylinder 4, opening the first through hole 7, while the second baffle 22 is in contact with the inner wall of the mixing cylinder 3, blocking the second through hole 8.
[0033] The control mechanism is used to switch the direction of concrete transfer, so that the concrete can be circulated and mixed or discharged in the bucket 2. It is controlled by the first hydraulic cylinder 24 to facilitate quick switching.
[0034] When the first baffle 21 moves down to make way for the first through hole 7, it will not block the space inside the core cylinder 4, allowing the concrete to fall smoothly.
[0035] The end of the second auger 9 extends into the wall of the mixing drum 3 and is provided with a worm wheel 27. A worm 28 that rotatably engages with the worm wheel 27 is provided inside the wall of the mixing drum 3. The worm 28 is connected to the transmission rod 30 via a universal joint 29 to the second gear 31 located at the top of the mixing drum 3. A second gear ring 32 that meshes with the second gear 31 is provided at the top of the material bucket 2.
[0036] When the mixing drum 3 rotates, the second gear 31 at the upper end rotates under the action of the second gear ring 32, which drives the worm 28 inside the wall of the mixing drum 3 to rotate, thereby causing the second auger 9 to rotate through the worm wheel 27, thus realizing the mixing of concrete in the material bucket 2.
[0037] Below the base plate 1, there is a cleaning plate 33 located in front of the discharge port 6 and a flat plate 34 located behind the discharge port 6. The cleaning plate 33 is telescopically mounted below the base plate 1 via a second hydraulic cylinder 35, and the flat plate 34 is telescopically mounted below the base plate 1 via a third hydraulic cylinder 36. The cleaning plate 33 and the flat plate 34 are slidably mounted on the mounting plate 37.
[0038] After the height of the base plate 1 is adjusted, the height of the cleaning plate 33 and the leveling plate 34 are adjusted. The cleaning plate 33 contacts the road surface without concrete pouring to clean up debris on the road surface. The height of the leveling plate 34 and the road surface is the thickness of the poured concrete. After the concrete is poured, it can be scraped to level the concrete, reducing subsequent operations.
[0039] By reducing the material discharge mechanism in traditional pouring equipment and directly setting the discharge port 6 at the bottom of the material bucket 2, the concrete travel is reduced, allowing the concrete to be in a better state during pouring. The resulting concrete pavement is more stable and the construction effect is improved.
[0040] Compared with the prior art, the present invention has the following beneficial effects: by setting a mixing drum and a core drum in the material bucket, the degree of concrete participation in mixing is increased, the possibility of concrete setting is reduced, and the concrete is kept in good condition. In addition, the long stroke of the discharge mechanism is reduced, so that the concrete can be discharged quickly to the road surface and poured onto the road surface in good condition, thereby improving the quality of concrete pavement.
