Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for concrete pouring, and in particular to a mixing and grouting device. Background Technology

[0002] In the construction of new energy projects such as mountain photovoltaic power stations and wind power plants, the cast-in-place pile foundation, as the core structure supporting photovoltaic panels and wind turbine towers, directly affects the safety, stability, and service life of the entire project due to its pouring quality. These projects are mostly located in mountainous areas with complex terrain, scattered construction areas, and often rugged access roads, some of which are even unable to support large construction vehicles. At the same time, the foundation construction has stringent requirements for the workability and uniformity of concrete, and any oversight in any link may lead to structural hazards.

[0003] Currently, the industry generally adopts two construction methods for pouring cast-in-place piles for mountain photovoltaic projects and wind turbine foundations: one is to use concrete mixer trucks to directly reach the pouring location for unloading and pouring; the other is to use concrete pump trucks to pump the concrete from a distance when mixer trucks cannot approach. For areas with poor access roads and where large equipment is difficult to access, a secondary transport of concrete is required using small trailers to complete the transfer from the centralized mixing point to the pouring point. Specifically, when concrete mixer trucks cannot reach the site directly due to road restrictions, the concrete is first unloaded from the mixer truck into the loading container of a small trailer, which then transports it along a simple road to the vicinity of the pouring point. Finally, the concrete is transferred manually or using simple equipment into the cast-in-place pile mold.

[0004] However, the above-mentioned existing technology has the following defects: when using ordinary small trailers for secondary transportation, the concrete is very prone to segregation due to factors such as bumpy transportation route and standing time, which affects the construction quality. Utility Model Content

[0005] This application provides a mixing and pouring device that solves the technical problem in the prior art where, during the secondary transportation of concrete in the construction of new energy projects such as mountain photovoltaic power stations and wind power plants, the concrete segregates due to factors such as bumpy transportation routes and standing time, affecting the construction quality.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a mixing and pouring device, comprising a hopper for holding concrete, the top surface of the hopper being open, an electric motor being supported on the upper edge of the hopper by a connecting frame, the housing of the electric motor being fixed to the upper end of the connecting frame, a mixing shaft being connected to the output end of the electric motor, a mixing blade being installed on the lower part of the mixing shaft, the mixing blade being located in the lower part of the hopper, and a discharge pipe being connected to the lower end of the hopper.

[0007] When using this device, concrete is poured in through the top opening of the hopper. The motor is started to drive the mixing shaft and mixing blades to mix the concrete in the hopper. The mixing process continues during transportation. After arriving at the pouring location, the concrete is discharged through the discharge pipe. Because the motor-driven mixing blades can continuously mix the concrete, it prevents stratification and segregation during transportation or when left to stand. This ensures the uniformity and workability of the concrete, solves the problem of concrete quality being affected during secondary transportation, improves construction quality, and the device is compatible with ordinary small trailers, making it suitable for areas with poor road conditions.

[0008] As a further improvement to the above solution, the connecting frame includes multiple inclined support rods. The lower end of the support rod is welded and fixed to the edge of the hopper opening, and the upper end of the support rod is fixedly connected to the housing of the motor. The motor is located directly above the hopper along the axis of the hopper. The multiple inclined support rods can evenly distribute the weight of the motor and the reaction force generated during the stirring process, ensuring the coaxiality of the stirring shaft and the hopper.

[0009] As a further improvement to the above solution, a stabilizing ring is fixedly attached to the outer periphery of the hopper. The stabilizing ring includes an inner ring and an outer ring. The inner wall of the inner ring is fixedly connected to the outer wall of the hopper via multiple first connecting rods, and the outer wall of the inner ring is fixedly connected to the inner wall of the outer ring via multiple second connecting rods. A hanging point is provided on the upper edge of the outer ring, which can be used to connect ropes. The stabilizing ring can increase the outer diameter of the device, making it easier to maintain balance during transportation and hoisting. The hanging point facilitates the connection of ropes, making it easier for hoisting equipment to lift the device and move it to the grouting position.

[0010] As a further improvement to the above scheme, multiple hanging points are evenly arranged along the circumference of the outer ring; this ensures that the device is subjected to balanced forces in all directions when it is hoisted, avoids tilting of the device due to uneven forces, and prevents concrete from spilling out during hoisting or moving.

[0011] As a further improvement to the above solution, the hopper includes an upper chamber and a lower chamber. The upper chamber is a funnel-shaped structure that is larger at the top and smaller at the bottom, while the lower chamber is a cylindrical structure. The discharge pipe is connected to the bottom surface of the lower chamber. The funnel-shaped structure of the upper chamber facilitates the rapid input of concrete raw materials and guides them downward to the lower chamber. The cylindrical structure of the lower chamber can lower the overall center of gravity of the device. Therefore, this structure not only improves the feeding efficiency and guides the concrete to gather in the mixing area, but also enhances the stability of the device during transportation.

[0012] As a further improvement to the above solution, the stirring shaft extends into the bottom of the hopper, and the stirring blade is a paddle impeller; the paddle blade can generate a composite stirring force in the axial and radial directions, so that the concrete flows in the circumferential direction while tumbling up and down, which can fully stir the concrete in the lower part of the hopper, thus improving the uniformity of mixing and preventing the concrete from segregating during transportation or standing.

[0013] As a further improvement to the above solution, multiple discharge pipes are provided; thus, they can be used simultaneously or individually according to actual filling needs. For example, opening multiple discharge pipes simultaneously during large-area filling can increase the filling speed, while using a single discharge pipe during filling in narrow areas makes it easier to control the filling position, thereby enhancing the adaptability and flexibility of the device in different filling scenarios.

[0014] As a further improvement to the above solution, an electric valve is installed on each discharge pipe.

[0015] As can be seen from the above technical solutions, this utility model has at least the following technical effects or advantages: 1. When using this device, concrete is poured in through the top opening of the hopper. The motor is started to drive the mixing shaft and mixing blades to mix the concrete in the hopper. The mixing process can be maintained during transportation. After arriving at the pouring location, the concrete is discharged through the discharge pipe. Because the motor drives the mixing blades to continuously mix the concrete, it prevents stratification and segregation during transportation or when it is left to stand. Therefore, it ensures the uniformity and workability of the concrete, solves the problem of the concrete quality being affected during secondary transportation, improves the construction quality, and the device is compatible with ordinary small trailers and is suitable for areas with poor road conditions.

[0016] 2. Since the hopper consists of a funnel-shaped upper chamber (larger at the top and smaller at the bottom) and a cylindrical lower chamber, and the discharge pipe is connected to the bottom of the lower chamber, the funnel-shaped structure of the upper chamber facilitates the rapid input of concrete raw materials and guides them downward to the lower chamber. The cylindrical structure of the lower chamber lowers the overall center of gravity of the device. Therefore, this structure not only improves the feeding efficiency and guides the concrete to gather in the mixing area, but also enhances the stability of the device during transportation. It is also conducive to the mixing blades fully mixing the concrete and ensuring the uniformity of the concrete.

[0017] 3. Because the mixing shaft extends into the bottom of the hopper and the mixing blades are paddle impellers, the paddle blades can generate a combined axial and radial mixing force, causing the concrete to flow in the circumferential direction while tumbling up and down. This can fully mix the concrete in the lower part of the hopper, thus effectively improving the mixing uniformity and preventing the concrete from segregating during transportation or standing, ensuring the construction quality of the concrete.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0021] This utility model discloses a mixing and pouring device, which includes a hopper 1 for holding concrete. The top surface of the hopper 1 is open. The upper edge of the hopper 1 is supported by a motor 3 through a connecting frame 2. The housing of the motor 3 is fixed to the upper end of the connecting frame 2. The output end of the motor 3 is connected to a mixing shaft 4. A mixing blade 5 is installed on the lower part of the mixing shaft 4. The mixing blade 5 is located in the lower part of the hopper 1. The lower end of the hopper 1 is also connected to a discharge pipe 11.

[0022] like Figure 1 As shown, the hopper 1 is a container structure with its top and bottom connected. The top opening is for feeding concrete raw materials, and the discharge pipe 11 at the bottom is the channel for concrete output. The connecting frame 2 is mounted on the edge of the opening of the hopper 1, thus suspending and supporting the motor 3 directly above the hopper 1. The output shaft of the motor 3 extends vertically downwards and is fixedly connected to the upper end of the mixing shaft 4 via a coupling. The lower end of the mixing shaft 4 extends into the lower part of the hopper 1, and the mixing blades 5 are completely inside the hopper 1. When the motor 3 starts, the mixing shaft 4 drives the mixing blades 5 to rotate inside the hopper 1, continuously mixing the concrete and preventing segregation during settling or transportation. The mixed concrete can be discharged through the discharge pipe 11 for pouring operations.

[0023] In actual operation, concrete raw materials are fed into the top opening of hopper 1, and motor 3 is started. Motor 3 drives the mixing shaft 4 and mixing blades 5 to rotate. The mixing blades 5 mix the concrete in hopper 1 to ensure that the concrete is mixed evenly and does not separate. If transportation is required, motor 3 can be kept running continuously during transportation. After arriving at the pouring location, mixing is stopped, and discharge pipe 11 is opened to allow the concrete to flow out from discharge pipe 11 under gravity, completing the pouring operation.

[0024] This device uses an electric motor 3 to drive the mixing shaft 4 and mixing blades 5 to continuously mix the concrete in the hopper 1, solving the problem of concrete segregation during traditional secondary transportation and ensuring the uniformity of the concrete and the quality of construction. Furthermore, the device has a compact overall structure, is compatible with ordinary small trailers and other transportation vehicles, and does not require large concrete mixer trucks or pump trucks, making it suitable for areas with poor access roads.

[0025] In the specific structure of the connecting frame 2, the connecting frame 2 includes four inclined support rods 201, which are evenly distributed along the circumferential direction of the edge of the hopper 1 opening. The lower end of each support rod 201 is welded and fixed to the edge of the hopper 1 opening, while the upper end is inclined towards the central axis of the hopper 1, eventually converging and fixing at the middle position of the motor 3 housing to form a conical support structure. The multiple inclined support rods 201 can evenly distribute the weight of the motor 3 and the reaction force generated during the mixing process, ensuring that the motor 3 is always directly above the hopper 1, guaranteeing the coaxiality of the mixing shaft 4 and the hopper 1, and preventing friction or collision between the mixing blades 5 and the inner wall of the hopper 1. At the same time, the above structure provides sufficient feeding space for the top opening of the hopper 1, facilitating the input of concrete raw materials and improving operational convenience.

[0026] A stabilizing ring 6 is fixedly attached to the outer periphery of the hopper 1. The stabilizing ring 6 includes an inner ring 601 and an outer ring 602, both of which are circular structures and are concentrically arranged on the upper outer periphery of the hopper 1. The inner wall of the inner ring 601 is fixedly connected to the outer wall of the hopper 1 by multiple first connecting rods 7, and the outer wall of the inner ring 601 is fixedly connected to the inner wall of the outer ring 602 by multiple second connecting rods 8. The first connecting rods 7 and the second connecting rods 8 are both short columnar structures, with 3-5 rods each, and are evenly distributed along the inner and outer walls of the inner ring 601, respectively.

[0027] The upper edge of the outer ring 602 is provided with a hanging point 9, which is a circular structure welded to the upper edge of the outer ring 602. The hanging point 9 can be connected to a rope, making it easier for the device to be lifted by hoisting equipment, thereby realizing the grouting operation. In the above structure, the outer diameter of the device can be increased by the stabilizing ring 6, making it easier for the device to be connected to the rope and lifted and moved to the grouting position.

[0028] Specifically, such as Figure 1As shown, the preferred number of hanging points 9 is four, which are evenly distributed along the circumference of the outer ring 602, with an included angle of 90° between any two adjacent hanging points 9. The evenly distributed hanging points 9 on the outer ring 602 ensure a more balanced force distribution during hoisting, helping to keep the hopper 1 horizontal and preventing concrete spillage due to tilting. Furthermore, when moving and adjusting the device, the multiple hanging points 9 on the stabilizing ring 6 allow for more stable adjustment of the device's angle and height, adapting to different grouting scenarios.

[0029] In the specific structure of hopper 1, hopper 1 includes an upper hopper 101 and a lower hopper 102, which are integrally formed. The upper diameter of the upper hopper 101 is larger than the lower diameter, and the sidewall of the upper hopper 101 has a certain inclination angle, thus forming a funnel-shaped structure. This funnel-shaped structure facilitates the rapid input of concrete raw materials and guides the concrete to flow naturally downward to the lower hopper 102. The lower hopper 102 is cylindrical, and the discharge pipe 11 is a circular pipe structure, welded to the bottom surface of the lower hopper 102 and connected to the interior of the lower hopper 102. In the above structure, the funnel shape of the upper hopper 101 can improve the feeding efficiency and guide the concrete to gather in the mixing area; the cylindrical structure of the lower hopper 102 lowers the center of gravity of the entire device, making the device stable during transportation.

[0030] like Figure 1 As shown, the mixing shaft 4 is made of solid round steel, with a length greater than the height of the hopper 1, and its lower end extends to the bottom of the lower hopper 102. The mixing blades 5 are two symmetrically arranged paddle-type blades, with a certain gap between the blade edges and the inner wall of the hopper 1 to avoid friction between the blades and the inner wall of the hopper. In the above structure, the mixing shaft 4 extends into the bottom of the hopper 1 and works with the paddle-type impeller to fully mix the concrete in the lower part of the hopper 1. The paddle-type blades can generate a combined axial and radial mixing force, causing the concrete to flow in a circumferential direction while tumbling up and down, thereby improving the mixing uniformity and effectively preventing concrete segregation.

[0031] like Figure 1 As shown, there are three discharge pipes 11, which are evenly distributed on the bottom surface of the lower chamber 102 and symmetrically arranged around the central axis. Each discharge pipe 11 has the same structure and dimensions, and is welded to the bottom surface of the lower chamber 102. Furthermore, each discharge pipe 11 is equipped with an electric valve 10. The installation of electric valves 10 on the discharge pipes 11 is a conventional feature and will not be described in detail. In this embodiment, by installing electric valves 10 on each discharge pipe 11, multiple discharge pipes 11 can be used simultaneously or individually as needed. For example, when filling a large area, opening multiple discharge pipes 11 simultaneously can increase the filling speed; when filling a narrow area, using a single discharge pipe 11 makes it easier to control the filling position.
