Description

Technical Field

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

[0002] Currently, concrete or cement mortar pouring is one of the important tasks at construction sites. In the process of pouring short columns for steel structure concrete foundations, where it is necessary to move the concrete pouring device and pour one column at a time, in order to improve the flexibility of pouring, the concrete pouring device is generally connected to the swing arm of the excavator, and the pouring is carried out in coordination with the movement of the excavator and the swing arm.

[0003] Chinese utility model patent CN220377865U discloses a high-efficiency concrete pouring device, including a concrete hopper, a support frame fixedly connected to the lower outer side of the concrete hopper, a high-efficiency conical discharge cylinder set in the middle of the lower end of the concrete hopper, and a discharge pipe set at the lower end of the high-efficiency conical discharge cylinder. The discharge pipe is L-shaped. It can achieve the sealing of the discharge port and the discharge port is located at the lower end of the inner side of the limiting cylinder by setting a limiting cylinder outside the discharge port. A gear-shaped sealing plate is rotatably connected to the upper front end of the discharge cylinder. At the same time, the gear-shaped sealing plate rotates around the inner wall of the limiting cylinder by meshing with the tooth groove, thereby achieving the sealing of the discharge port and the control of the discharge. After sealing, rotating the gear-shaped sealing plate can scrape the concrete off by misaligning the rear end wall of the gear-shaped sealing plate with the discharge port, thereby improving the cleaning efficiency of the gear-shaped sealing plate and ensuring the normal operation of the gear-shaped sealing plate, thus improving the discharge stability of the pouring device.

[0004] The above solution has the following drawbacks: although the discharge port is cleaned by a scraper, concrete residue will still appear inside the mixing tank, which is inconvenient to clean and affects normal use.

[0005] Chinese patent discloses a high-efficiency concrete pouring device for public construction projects (authorization announcement number CN223236641U). This patented technology uses a connecting plate to insert an installation block at one end into the installation groove. A sliding block slides outside a linear guide rail, causing the sliding block to lift and lower the connecting block. The connecting block pushes the sealing cover to seal the top of the mixing drum. A servo motor drives the connecting rod to rotate inside the mixing drum. The concrete is mixed by a mixing rod set outside the connecting rod, which facilitates operation. During the rotation of the connecting rod, the connecting plate rotates inside the mixing drum. A cleaning block set between the connecting plates fits against the inner wall of the mixing drum, allowing the concrete inside the mixing drum to be cleaned, preventing concrete from sticking to the inside of the mixing drum, making cleaning convenient and easy to use.

[0006] However, it has certain drawbacks: during the rotating scraping process, the stripped concrete will continue to adhere to the surface of the cleaning block itself. Due to the lack of a dynamic detachment mechanism in its static fixed structure, some of the adhered material cannot be effectively thrown off. As the mixing process progresses, the concrete accumulated on the surface of the cleaning block will continue to thicken, which not only weakens the scraping effect, but also forms a hardened layer due to the hardening of the adhered material, which increases the mixing resistance and reduces the mixing uniformity, significantly increasing the cost of manual cleaning and equipment downtime losses. Utility Model Content

[0007] The purpose of this invention is to provide a concrete pouring device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A concrete pouring device includes a pouring tank body and a tank cover at the upper end of the pouring tank body. A U-shaped seat is fixedly connected to the upper surface of the tank cover. A motor is fixedly connected to the upper surface of the U-shaped seat. A rotating rod is fixedly connected to the output end of the motor.

[0011] Support sleeves are fixedly connected to both the front and rear surfaces of the rotating rod, and a support rod is movably connected inside the support sleeve. A support block is fixedly connected to the lower end of the support rod.

[0012] The right side surface of the U-shaped seat is provided with a lifting component that drives the rotating tube to reciprocate up and down.

[0013] As a further embodiment of this utility model: the lifting component includes a seat bearing, a rotating shaft is installed inside the seat bearing, a bevel gear one is fixedly connected to the left end of the rotating shaft, a bevel gear two is meshed with the left side of the bevel gear one, a rotating plate one is fixedly connected to the right end of the rotating shaft, a rotating plate two is rotatably connected to the lower end of the right side surface of the rotating plate one, a rotating plate three is rotatably connected to the lower end of the left side surface of the rotating plate two, a lifting plate is fixedly connected to the lower end of the rotating plate three, and a limit rod is movably connected through the interior of the lifting plate located on the left side of the rotating plate three.

[0014] As a further embodiment of this utility model: the seat bearing is fixedly connected to the inner right side surface of the U-shaped seat, the rotating shaft movably passes through the right side surface of the U-shaped seat, the second bevel gear is fixedly sleeved on the outside of the rotating rod, the lifting plate is slidably connected through the right side surface of the U-shaped seat, and the left end of the lifting plate is rotatably sleeved on the outside of the rotating tube, and the lower end of the limiting rod is fixedly connected to the upper surface of the can lid.

[0015] As a further embodiment of this utility model: the rotating pipe extends through the tank cover, the stirring blade is located inside the casting tank body, and the support block is fixed to one side surface of the rotating pipe.

[0016] As a further embodiment of this utility model: the scraper includes two support plates, upper and lower, both of which are fixedly sleeved on the outside of the rotating pipe, and scrapers are fixedly connected between the left and right ends of the two support plates, with the scrapers movably fitting against the inner side of the casting tank body.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention uses a motor to drive a rotating rod to rotate, and transmits torque to the rotating tube via a support sleeve, support rod, and support block. This drives the mixing blades and scraper to rotate synchronously, achieving efficient mixing of concrete materials. Simultaneously, the rotation of the rotating rod drives the rotating shaft to rotate via a bevel gear pair. This rotational motion is then converted into the vertical reciprocating motion of the lifting plate through a linkage mechanism consisting of rotating plate one, rotating plate two, and rotating plate three. Ultimately, this drives the rotating tube to continuously rotate while simultaneously lifting and lowering axially. This combined motion not only significantly enhances the uniformity and efficiency of mixing and effectively prevents material clumping and segregation, but also allows the scraper to automatically scrape off and throw off the concrete adhering to its surface during the lifting and lowering process, maintaining the cleanliness and continuous working efficiency of the scraper, thereby ensuring a smooth pouring process and the final quality of the concrete.

[0026] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment of the present invention, a concrete pouring device includes a pouring tank body 1 and a tank cover 2 at the upper end of the pouring tank body 1; the internal chamber of the pouring tank body 1 is used to hold concrete materials, and a controllable valve, such as a ball valve or a butterfly valve, is installed at its bottom outlet. The valve can be connected to a conveying hose or a rigid pipe through a quick connector so as to directionally convey the concrete to the pouring area; the pouring tank body 1 and the tank cover 2 are fixed together by bolts, and the upper surface of the tank cover 2 can be provided with a feed port, which can be connected to a feed pipe or directly fed with concrete raw materials;

[0027] A U-shaped seat 3 is fixed to the upper surface of the can lid 2; the opening of the U-shaped seat 3 faces downward.

[0028] A motor 4 is fixed to the upper surface of the U-shaped seat 3; the motor 4 is an explosion-proof or variable frequency speed control motor, and its power and torque are selected according to the tank volume and concrete grade.

[0029] A rotating rod 5 is fixedly connected to the output end of the motor 4. A rotating tube 6 is movably sleeved on the outside of the rotating rod 5. The rotating tube 6 movably passes through the tank cover 2. Multiple stirring blades 7 are uniformly fixed to the outer surface of the rotating tube 6. The stirring blades 7 are located inside the casting tank body 1. The stirring blades 7 are distributed in a spiral ribbon or paddle shape. Their tilt angle and blade area are optimized by fluid simulation, which can realize efficient mixing and anti-segregation mixing of concrete materials and prevent concrete from clumping.

[0030] exist Figures 1-3 In the middle: A wall scraper 8 is provided on the outside of the rotating tube 6, above the uppermost stirring blade 7 and below the lowermost stirring blade 7. The wall scraper 8 includes two support plates 9, which are fixedly sleeved on the outside of the rotating tube 6. The upper support plate 9 is located above the uppermost stirring blade 7, and the lower support plate 9 is located below the lowermost stirring blade 7. The support plates 9 are fixed to the rotating tube 6 by bolts.

[0031] Scraper 10 is fixedly connected between the left and right ends of the two support plates 9. The scraper 10 is movably attached to the inner side of the casting tank body 1. The scraper 10 rotates with the rotating pipe 6 and is used to clean the inner wall of the casting tank body 1. The scraper 10 is preferably made of polyurethane or nylon 66 and is fixed to the support plate 9 by bolts for easy disassembly and maintenance.

[0032] exist Figure 1 , Figure 2 , Figure 4 and Figure 5 In the middle section: Support sleeves 11 are fixedly connected to both the front and rear surfaces of the rotating rod 5. A support rod 12 is movably connected through the inside of the support sleeve 11. A support block 13 is fixedly connected to the lower end of the support rod 12. The support block 13 is fixedly connected to one side surface of the rotating tube 6. When the rotating rod 5 rotates, its torque is transmitted to the rotating tube 6 through the support sleeve 11, the support rod 12 and the support block 13, causing it to rotate synchronously. The support rod 12 slides axially relative to the support sleeve 11, providing freedom for the subsequent lifting and lowering movement of the rotating tube 6. This ensures that the rotating tube 6 will not rotate relative to the rotating rod 5 during the rotation process, but it can undergo relative axial displacement.

[0033] The right side surface of the U-shaped seat 3 is provided with a lifting component 14 that drives the rotating tube 6 to reciprocate up and down. The lifting component 14 includes a seat bearing 15, which is fixed to the inner right side surface of the U-shaped seat 3. A rotating shaft 16 is installed inside the seat bearing 15. The seat bearing 15 includes a bearing housing and a bearing fixed inside the bearing housing. The bearing includes an outer bearing ring and an inner bearing ring that rotates inside the outer bearing ring. The outer bearing ring is fixed to the bearing housing, the bearing housing is fixed to the U-shaped seat 3, and the rotating shaft 16 is fixed to the inner bearing ring. Therefore, the seat bearing 15 and the rotating shaft 16 are in a state of mutual rotation.

[0034] The rotating shaft 16 moves through the right side surface of the U-shaped seat 3. A bevel gear 17 is fixedly connected to the left end of the rotating shaft 16. A bevel gear 28 is meshed with the left side of the bevel gear 17. The bevel gear 28 is fixedly sleeved on the outside of the rotating rod 5. A rotating plate 19 is fixedly connected to the right end of the rotating shaft 16. A rotating plate 20 is rotatably connected to the lower end of the right side surface of the rotating plate 19. A rotating plate 31 is rotatably connected to the lower end of the left side surface of the rotating plate 20. A lifting plate 22 is fixedly connected to the lower end of the rotating plate 31.

[0035] The length of the rotating plate 20 is designed such that the rotating plate 3 21 will not contact the rotating plate 19 during the rotation of the rotating plate 19, and the lifting plate 22 is located below the support block 13.

[0036] Rotating plate 19, rotating plate 20 and rotating plate 3 together form a linkage mechanism, which converts the rotational motion of rotating shaft 16 into linear motion at the end of rotating plate 3 21, thereby driving lifting plate 22 to perform up and down reciprocating motion.

[0037] The lifting plate 22 is slidably connected to the right side surface of the U-shaped seat 3, and the left end of the lifting plate 22 is rotatably sleeved on the outside of the rotating tube 6; the lifting plate 22 and the rotating tube 6 are rotatably connected by a bearing, so that the lifting plate 22 can drive the rotating tube 6 to rise and fall, and does not interfere with the rotational movement of the rotating tube 6.

[0038] The interior of the lifting plate 22 is located on the left side of the rotating plate 21 and is movably connected to the limiting rod 23. The lower end of the limiting rod 23 is fixed to the upper surface of the can cover 2. The limiting rod 23 and the hole on the lifting plate 22 form a sliding pair, which effectively restricts the degree of freedom of the lifting plate 22, so that it can only perform precise vertical guiding movements.

[0039] The rotation of the rotating rod 5 drives the rotating tube 6 to rotate, and at the same time, the meshing of two bevel gears drives the rotating shaft 16 to rotate, thereby driving the lifting plate 22 to move up and down repeatedly, which in turn drives the rotating tube 6 and the scraper 8 to move up and down repeatedly, which not only improves the mixing effect, but also allows the concrete adhering to the surface of the scraper 8 to fall off.

[0040] When the rotating pipe 6 is raised or lowered to the highest or lowest point of its stroke, the scraper 8 installed on it will never come into contact with the lower surface of the tank cover 2 or the inner bottom surface of the casting tank body 1, thus completely avoiding motion interference.

[0041] exist Figure 1 In the middle: A base 24 is installed below the casting tank body 1. Fixing plates 25 are fixed to both ends of the upper surface of the base 24. Fixing columns 26 are fixed to the upper part of the opposite side surface of the two fixing plates 25. The fixing columns 26 are fixed to one side surface of the casting tank body 1. Multiple mounting holes or anchor bolt holes can be provided on the lower surface of the base 24 so as to fix it to the ground or mobile base by anchor bolts to prevent displacement during operation.

[0042] The working principle of this utility model is as follows: After concrete material is put into the internal cavity of the casting tank 1 through the feed port on the tank cover 2, the motor 4 is started. The motor 4 drives the rotating rod 5 to rotate. The rotating rod 5 transmits torque to the rotating pipe 6 through the support sleeve 11, support rod 12 and support block 13 on it, driving the rotating pipe 6 and its stirring blades 7 and scraper 8 to rotate synchronously, so as to efficiently mix the concrete to prevent agglomeration and segregation; at the same time, the rotation of the rotating rod 5 drives the rotating shaft 16 to rotate within the seat bearing 15 through the meshing of the bevel gear 18 fixed on it and the bevel gear 17 fixed to the left end of the rotating shaft 16. The rotating plate 19 on the right end of 16 rotates accordingly, and the rotational motion is converted into the vertical reciprocating motion of the lifting plate 22 through the linkage mechanism composed of rotating plate 20 and rotating plate 21. The lifting plate 22 drives the rotating pipe 6, the stirring blade 7 and the wall scraper 8 to move axially while rotating continuously through its left end and rotating pipe 6. This compound motion significantly enhances the uniformity of mixing and can scrape off the material adhering to the wall scraper 8. After mixing is completed, the valve at the bottom of the pouring tank 1 is opened, and the concrete material is transported to the designated area for pouring through the pipeline. During the pouring process, the mixing does not stop to avoid material residue.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
