Description

Technical Field

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

[0002] In the current booming development of infrastructure projects, concrete, as a core construction material, directly affects the quality and efficiency of the project due to the performance of its pouring equipment. Currently, traditional concrete pouring equipment has many limitations. Firstly, the mixing devices often use single straight blades, which easily create vortex blind zones during the mixing process, leading to uneven mixing of cement, aggregates, and other components, often resulting in localized insufficient strength and other quality issues. Secondly, discharge control relies on manual valves, which have low adjustment precision and slow response, making it difficult to adapt to the needs of large-volume continuous pouring or high-precision component construction. For example, in the construction of high-rise building pile foundations, the lag in valve adjustment causes fluctuations in concrete flow, easily leading to pile diameter reduction or segregation. Furthermore, the fixed discharge port structure of traditional equipment cannot quickly adapt to different construction scenarios (such as conical discharge ports for pile foundation pouring and flat discharge ports for wall pouring), lacking construction flexibility. In addition, the equipment is inconvenient to move and position, making it difficult to adapt to complex construction environments, and frequent handling may also affect equipment stability. Therefore, those skilled in the art provide a concrete pouring equipment for infrastructure construction to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a concrete pouring device for infrastructure construction to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A concrete pouring device for infrastructure construction includes a pouring box, a mixing structure, and a control variable structure. The mixing structure is fixedly connected to the top of the pouring box, a base plate is fixedly connected to the bottom of the pouring box, and a control variable structure is fixedly connected to the lower part of one side of the pouring box.

[0006] As a further embodiment of this utility model: the stirring structure includes a motor, a rotating shaft, a stirring shaft, a spiral stirring blade, a circulating cylinder, and a fixed frame. The stirring shaft is installed inside the circulating cylinder. The top and bottom of the stirring shaft are fixedly connected to rotating shafts. The rotating shaft at the top, on the side away from the stirring shaft, passes through the top of the casting box and is rotatably connected to it, and is fixedly connected to the power output shaft of the motor.

[0007] As a further embodiment of this utility model: the rotating shaft at the bottom is rotatably connected to the bottom wall of the casting box on the side away from the stirring shaft, and several spiral stirring blades are fixedly connected at equal intervals on the stirring shaft and inside the circulation cylinder. The outer walls on both sides of the circulation cylinder are fixedly connected to the inner wall of the casting box through a fixing bracket, and the top and bottom of the circulation cylinder are respectively provided with an upper opening and a lower opening.

[0008] As a further embodiment of this utility model: the control variable structure includes a fixed frame, a connecting block, an electric push rod, a connecting frame, a baffle and a slide groove. The top of the fixed frame is provided with a slide groove, and a baffle is slidably connected in the slide groove. The lower parts of both sides of the fixed frame are fixedly connected with connecting blocks.

[0009] As a further embodiment of this utility model: an electric push rod is fixedly connected to the top of the connecting block, and a connecting frame is fixedly connected to the side of the electric push rod away from the connecting block. The connecting frame is connected to the baffle by a second screw, and the second screw is threadedly connected to the connecting frame and the baffle.

[0010] As a further improvement of this utility model: a feed inlet is fixedly connected to the upper part of one side of the casting box, and movable wheels are fixedly connected to the four corners of the bottom of the base plate. The movable wheels are locked wheels, and a traction rod is fixedly connected to one side of the top of the base plate. An anti-slip rod is fixedly connected to the traction rod.

[0011] As a further improvement of this utility model: the fixed frame on the control variable structure is detachably connected to a connecting frame on the side away from the pouring box, and the two sides of the connecting frame are connected to the fixed frame by two first screws, and the first screws are threadedly connected to the fixed frame and the connecting frame.

[0012] As a further embodiment of this utility model: an observation window is fixedly connected to one side of the casting box, and a discharge frame is fixedly connected to the side of the connecting frame away from the control variable structure. A groove is provided at the lower part of one side of the discharge frame, and a vibrator is fixedly installed inside the groove.

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

[0014] 1. During use, the equipment is moved to the construction position by the movement wheels on the bottom of the base plate and the operator pushing or pulling the anti-slip bar on the traction rod. The anti-slip bar can increase the friction of the hand and prevent slippage when pushing or pulling. When it is moved to the appropriate position, the movement wheels are locked to stabilize the equipment.

[0015] 2. Next, after pouring the concrete raw materials into the inlet, start the motor. Its output shaft drives the top rotating shaft connected to it to rotate. Since the mixing shaft and the rotating shaft are fixed, and the bottom rotating shaft is rotatably connected to the bottom wall of the pouring box, the motor power is transmitted to the mixing shaft to drive its rotation. As the spiral mixing blades installed on the mixing shaft rotate with the shaft, the axial thrust generated by them causes the concrete raw materials to move upward along the inner wall of the circulation cylinder. The pressure difference formed by the rotation of the blades creates an upward flow channel inside the circulation cylinder. At the same time, the blade edges generate shear force on the concrete raw materials, dispersing the agglomerated materials. The rotation of the mixing shaft pushes the concrete raw materials downward to gather. A low-pressure zone is formed, which causes the concrete material at the bottom of the casting box to be sucked into the circulation cylinder. The concrete material reaching the top returns to the main space of the casting box through the upper opening in a diffusion manner. After the discharge flow collides with the box wall, it forms downward and horizontal flow, and finally all of them re-enter the lower opening to complete the circulation. The concrete material is continuously mixed during the continuous circulation process. The combination of the circulation cylinder and the casting box ensures that the concrete material at the edge can participate in the circulation, eliminating mixing dead corners. The spiral mixing blades generate repeated shearing action on the concrete material, realizing the uniform dispersion of the concrete material, thereby achieving its full mixing and providing a uniform material for the subsequent casting process.

[0016] 3. After thorough mixing, the electric push rod is activated. The electric push rod, through the connecting frame and the second screw, drives the baffle to slide within the chute, achieving stepless adjustment of the discharge port cross-sectional area. When an increased flow rate is required, the electric push rod extends, causing the baffle to move backward and expanding the discharge port cross-sectional area; conversely, the push rod shortens to reduce the flow rate. This adjustment method enables real-time dynamic adjustment, avoiding flow fluctuations caused by manual operation delays in traditional valves. Furthermore, the fixed frame and the connecting frame are detachably connected by the first screw, supporting quick replacement of discharge frames adapted to different construction scenarios (such as conical discharge ports for pile foundation pouring and flat discharge ports for wall pouring), significantly improving construction flexibility. After the discharge process is initiated, concrete flows from the bottom of the pouring box into the control variable structure under gravity. After adjustment by the baffle, it is discharged through the discharge frame. Simultaneously, the vibrator in the groove at the bottom of the discharge frame is activated, using high-frequency vibration to reduce concrete adhesion and blockage, ensuring continuous and stable discharge.

[0017] 4. During the pouring process, the operator can observe the remaining amount of concrete and the mixing status in the pouring box in real time through the observation window, and replenish raw materials or adjust the mixing speed in a timely manner. After the construction is completed, turn off the motor and vibrator, and reset the electric push rod to completely seal the discharge port with the baffle to prevent the remaining material from dripping. Disassemble the connecting frame and baffle to clean the inside of the pouring box and the discharge channel. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This embodiment provides a concrete pouring device for infrastructure construction, including a pouring box 5, a mixing structure 6, and a control variable structure 7. The mixing structure 6 is fixedly connected to the top of the pouring box 5, and a base plate 1 is fixedly connected to the bottom of the pouring box 5. The control variable structure 7 is fixedly connected to the lower part of one side of the pouring box 5. A feed inlet 10 is fixedly connected to the upper part of one side of the pouring box 5. Four movable wheels 2 are fixedly connected to the four corners of the bottom of the base plate 1, and the movable wheels 2 are locking wheels. A traction rod 3 is fixedly connected to the top side of the base plate 1, and an anti-slip rod 4 is fixedly connected to the traction rod 3. The device moves to the construction position by pushing or pulling the anti-slip rod 4 on the traction rod 3, using the movable wheels 2. The anti-slip rod 4 increases hand friction and prevents pushing or pulling. When the equipment slips during operation, the moving wheels 2 are locked to provide stable support when the equipment is moved to the appropriate position. A connecting frame 11 is detachably connected to the fixed frame 71 on the side away from the pouring box 5 on the control variable structure 7. The two sides of the connecting frame 11 are connected to the fixed frame 71 by two first screws 14, and the first screws 14 are threadedly connected to the fixed frame 71 and the connecting frame 11.

The observation window 8 can monitor the uniformity of concrete mixing in real time to avoid clumping and stratification, and at the same time, it can keep track of the remaining material to facilitate timely replenishment and ensure continuous operation.

[0026] Example 2

[0027] Reference Figure 3-4This embodiment is based on the previous embodiment, but differs in that the stirring structure 6 includes a motor 61, a rotating shaft 62, a stirring shaft 63, spiral stirring blades 64, a circulation cylinder 65, and a fixing frame 66. The circulation cylinder 65 houses the stirring shaft 63. Rotating shafts 62 are fixedly connected to both the top and bottom of the stirring shaft 63. The top rotating shaft 62, away from the stirring shaft 63, extends through the top of the casting box 5 and is rotatably connected to it, and is also fixedly connected to the power output shaft of the motor 61. The bottom rotating shaft 62, away from the stirring shaft 63, is rotatably connected to the bottom wall of the casting box 5. A plurality of spiral stirring blades 64 are equidistantly fixedly connected to the stirring shaft 63 and inside the circulation cylinder 65. The outer walls of both sides of the circulation cylinder 65 are connected to the casting box 5 via the fixing frame 66. The inner wall is fixedly connected, and the top and bottom of the circulation cylinder 65 are respectively provided with upper and lower openings. After the motor 61 starts, its output shaft drives the top rotating shaft 62 connected to it to rotate. Since the stirring shaft 63 is fixed to the rotating shaft 62, and the bottom rotating shaft 62 is rotatably connected to the bottom wall of the casting box 5, the power of the motor 61 is transmitted to the stirring shaft 63 to drive it to rotate. When the spiral stirring blades 64 installed on the stirring shaft 63 rotate with the shaft, the axial thrust generated by them causes the concrete raw material to move upward along the inner wall of the circulation cylinder 65. The pressure difference formed by the rotation of the blades forms an upward flow channel inside the circulation cylinder 65. At the same time, the blade edges generate shear force on the concrete raw material, dispersing the agglomerated material. The rotation of the stirring shaft 63 pushes the concrete raw material to gather at the lower opening to form In the low-pressure zone, the concrete material at the bottom of the casting box 5 is drawn into the circulation cylinder 65. The concrete material reaching the top returns to the main space of the casting box 5 through the upper opening in a diffusion manner. After the discharge flow collides with the box wall, it forms downward and horizontal flows, and finally all re-enters the lower opening to complete the circulation. The concrete material is continuously mixed during the continuous circulation process. The combination of the circulation cylinder 65 and the casting box 5 ensures that the concrete material at the edge can participate in the circulation, eliminating mixing dead corners. The spiral mixing blades 64 generate repeated shearing action on the concrete material, realizing the uniform dispersion of the concrete material, thereby achieving its full mixing and providing uniform material for subsequent casting processes. The control variable structure 7 includes a fixed frame 71, a connecting block 72, an electric push rod 73, a connecting frame 74, and a stop. The fixed frame 71 has a plate 75 and a chute 76. The top of the fixed frame 71 has a chute 76, and a baffle 75 is slidably connected in the chute 76. Connecting blocks 72 are fixedly connected to the lower parts of both sides of the fixed frame 71. An electric push rod 73 is fixedly connected to the top of the connecting blocks 72. A connecting frame 74 is fixedly connected to the side of the electric push rod 73 away from the connecting blocks 72. The connecting frame 74 is connected to the baffle 75 by a second screw. The second screw is threadedly connected to the connecting frame 74 and the baffle 75. After the mixture is stirred evenly, the electric push rod 73 is driven to move. The electric push rod 73 drives the baffle 75 to slide in the chute 76 through the connecting frame 74 and the second screw, so as to realize stepless adjustment of the cross-sectional area of ​​the discharge port. When it is necessary to increase the flow rate, the electric push rod 73 extends to move the baffle 75 backward, thereby expanding the cross-sectional area of ​​the discharge port.Conversely, shortening the push rod reduces the flow rate. This adjustment method allows for real-time dynamic adjustment, avoiding flow fluctuations caused by manual operation delays in traditional valves. Furthermore, the fixed frame 71 and the connecting frame 11 are detachably connected via the first screw 14, supporting quick replacement of the discharge frame 9 to suit different construction scenarios (such as a conical discharge port for pile foundation pouring and a flat discharge port for wall pouring), significantly improving construction flexibility.
