Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of foam polymer soil, in particular, relates to a kind of foam polymer soil stirring mixing pumping device. BACKGROUND

[0002] In the existing foam light soil production system, the pumping mixing and stirring system is integrated in the vehicle-mounted equipment. In the prior art, the light soil is pumped by a hose pump. However, in the production process of foam polymer soil, the foam polymer soil has small flow value and large viscosity, and the hose pump cannot meet the pumping requirements. Moreover, the pumping mixing and stirring system in the prior art has a split structure, which occupies a large space.

[0003] Therefore, there is an urgent need for a foam polymer soil stirring mixing and pumping device that effectively utilizes space and facilitates rapid production. CONTENT OF THE UTILITY MODEL

[0004] To overcome the above-mentioned deficiencies, the present application provides a foam polymer soil stirring mixing and pumping device that effectively utilizes the existing space inside the equipment box and integrates the pumping system and the mixing system into a whole, facilitating rapid production.

[0005] In a first aspect, the present application provides a foam polymer soil stirring mixing and pumping device, and the technical solution is as follows:

[0006] The pumping hydraulic cylinder is connected to one side of the pump feed cylinder through an extension cylinder rod, and the other side of the pump feed cylinder is connected to the bottom of the hopper through an S pipe valve;

[0007] The hopper is used to store the material to be pumped, and the hopper is connected to the concrete cylinder through a discharge port. The outlet of the concrete cylinder is connected to the mixer through a pipeline.

[0008] The truss connects and integrates the pumping hydraulic cylinder, the pump feed cylinder, the hopper, the S pipe valve, the mixer and the concrete cylinder into a pumping device.

[0009] The foam polymer soil stirring mixing and pumping device provided by the present application uses hydraulic pumping instead of hose pumping, and integrates the pumping, stirring and mixing systems together through a truss, successfully solving the problems of difficulty in pumping foam polymer soil and large space occupation of the system. The hydraulic pumping system provides sufficient power to overcome the high viscosity of foam polymer soil, and the overall integrated design optimizes the space utilization.

[0010] Further, the present application also provides an oil cylinder piston arranged inside the pump feed cylinder, which reciprocates by pushing the oil cylinder piston through the extension cylinder rod to realize the suction and pumping of the material.

[0011] The foam polymer soil stirring and mixing pumping device provided by the application realizes effective suction and pumping of the material by arranging an oil cylinder piston in the pump feeding cylinder and reciprocating the oil cylinder piston by using the telescopic oil cylinder rod. This design is particularly suitable for processing foam polymer soil which has small flow value and large viscosity, and can overcome the limitations of hose pumps when processing such materials. Through the reciprocating movement of the telescopic oil cylinder rod, the oil cylinder piston forms alternating negative pressure and positive pressure in the pump feeding cylinder, which are used for suction and pumping of the material respectively, so that efficient conveying of the foam polymer soil is realized. This pumping mode not only meets the pumping requirements of the foam polymer soil, but also improves the pumping efficiency.

[0012] Further, the application also proposes that the S pipe valve driving oil cylinder drives the S pipe valve to swing left and right to make the material enter the concrete cylinder from the hopper.

[0013] The foam polymer soil stirring and mixing pumping device provided by the application realizes the transmission process of the material from the hopper to the concrete cylinder. The S pipe valve driving oil cylinder drives the S pipe valve to swing left and right, so that the S pipe valve is switched between the hopper and the concrete cylinder, thereby controlling the flow direction of the material. When the S pipe valve swings towards the hopper, the material flows from the hopper into the S pipe valve; when the S pipe valve swings towards the concrete cylinder, the material flows from the S pipe valve into the concrete cylinder. This swinging mode can effectively control the flow of the material and ensure that the material can smoothly enter the concrete cylinder from the hopper.

[0014] Further, the application also proposes that the concrete cylinder is provided with a stirring motor for driving the stirring blades.

[0015] The foam polymer soil stirring and mixing pumping device provided by the application can fully stir the material entering the concrete cylinder, thereby improving the mixing uniformity. At the same time, the S pipe valve driving oil cylinder controls the process of the material entering the concrete cylinder from the hopper, and cooperates with the stirring motor to realize continuous stirring and pumping of the material. This design not only improves the stirring efficiency, but also ensures the uniformity of the material.

[0016] Further, the application also proposes that a grid is further included for filtering the stirred slurry.

[0017] The foam polymer soil stirring and mixing pumping device provided by the application effectively improves the quality and pumping efficiency of the foam polymer soil by adding a filtering link between stirring and pumping. The use of the grid is simple and effective, does not significantly increase the complexity of the device, and can significantly improve the uniformity and purity of the slurry, thereby providing better protection for subsequent pumping and construction.

[0018] Further, the application also proposes that a jacking hydraulic oil cylinder is arranged on the truss for lifting and lowering the pumping device.

[0019] This application achieves the lifting function of the pumping device by installing a lifting hydraulic cylinder on the truss. This design allows the entire device to be adjusted in height according to actual needs, increasing the device's flexibility and applicability. The lifting hydraulic cylinder can control the height of the entire pumping device, facilitating docking with other equipment and adapting to different working environments. This design also facilitates transportation and storage of the device, allowing the height to be lowered when needed, improving space utilization.

[0020] Furthermore, the present application also proposes that it also includes an electric motor for extracting hydraulic oil from the hydraulic oil tank, pressurizing it, and then driving various components to do work.

[0021] The present application provides a foam polymer soil stirring and mixing pumping device, which solves the problems of dispersed energy utilization and low efficiency of traditional split systems by setting an electric motor as a unified power source, and realizes the centralization and efficiency of the power system of the pumping device.

[0022] Furthermore, the present application also proposes that the electric motor is connected to a plunger pump, and the plunger pump is a main oil pump for providing power to the pumping hydraulic cylinder.

[0023] This application provides a foamed polymer soil mixing and pumping device that solves the problem of powering the pumping hydraulic cylinder. An electric motor serves as the initial power source, and a plunger pump, a key component for energy conversion and pressure boosting, together ensures the pumping hydraulic cylinder receives sufficient power to complete the task of pumping the foamed polymer soil. This design not only improves the system's pumping capacity but also enhances the applicability and efficiency of the entire device.

[0024] Furthermore, the present application also proposes that the plunger pump is connected to a double gear pump for providing power to the stirring motor and the lifting hydraulic cylinder.

[0025] The present application provides a foamed polymer soil mixing and pumping device, which forms a complete power transmission system by connecting a plunger pump to a duplex gear pump. The plunger pump serves as the main oil pump, responsible for providing power to the pumping hydraulic cylinder, while the duplex gear pump is specifically responsible for supplying energy to the mixing motor and the lifting hydraulic cylinder. This design not only achieves a reasonable distribution of power, but also improves the working efficiency of the entire system. The mixing motor can obtain sufficient power to mix the materials, and the lifting hydraulic cylinder can also obtain sufficient power to realize the lifting and lowering of the pumping device. This power distribution method effectively solves the technical problem of how to provide power to the mixing motor and the lifting hydraulic cylinder, so that the entire foamed polymer soil mixing and pumping device can operate efficiently and stably.

[0026] Furthermore, the present application also proposes that it also includes an energy accumulator for absorbing the high-pressure hydraulic oil pumped by the electric motor to drive the S-tube valve to drive the oil cylinder under the control of the electronic control box.

[0027] The application drives the S-valve driving oil cylinder by absorbing high-pressure hydraulic oil and being controlled by the electric control box, thereby effectively utilizing hydraulic energy storage and release in the pumping process of the foam polymer. The energy storage device functions to ensure sufficient energy to push the high-viscosity material from the hopper to the outside for efficient pumping process.

[0028] Beneficial effects: The foam polymer mixing and pumping device provided by the application can generate sufficient pumping power by combining the pumping hydraulic oil cylinder and the pump feeding cylinder, thereby solving the problem of small flow value and large viscosity of the foam polymer, which is difficult to pump. The S-valve realizes directional transportation of the material by connecting the hopper and the concrete cylinder. The concrete cylinder and the mixer realize the mixing function of the material. The truss as a support structure integrates each component into a whole, effectively reduces the space occupation, and uses the hydraulic pump instead of the hose pump, thereby solving the problem of small flow value and large viscosity of the foam polymer, and having the advantages of compact structure, high space utilization, and high production efficiency.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0035] In foamed lightweight soil production systems, traditional pumping and mixing systems typically utilize vehicle-mounted equipment, using hose pumps to pump the lightweight soil. However, this technology faces significant challenges when processing foamed aggregate soil. Foamed aggregate soil has a low flow rate and high viscosity, making hose pumps incapable of meeting pumping requirements. Furthermore, existing pumping and mixing systems utilize a split-body structure, which takes up a significant amount of space. These issues severely impact foamed aggregate soil production efficiency and equipment space utilization. Specifically, when operators attempt to initiate the pumping process, the hose pump's rotor is unable to overcome the material's high viscosity resistance, resulting in frequent blockages or shutdowns. Furthermore, due to the split-body structure, the entire system can occupy 20-30 square meters, creating significant deployment challenges on construction sites with limited space. This not only reduces production efficiency but also increases equipment transportation and installation costs.

[0036] In order to solve this problem, the present application proposes a foam polymer soil mixing and pumping device, including a pumping hydraulic cylinder 3, which is connected to one side of the pumping cylinder 5 through a telescopic cylinder rod, and the other side of the pumping cylinder 5 is connected to the bottom of the hopper 9 through an S-tube valve 8; the hopper 9 is used to store the material to be pumped, and the hopper 9 is connected to the concrete cylinder 19 through the discharge port, and the outlet of the concrete cylinder 19 is connected to the mixer 12 through a pipeline; the truss 1 connects the pumping hydraulic cylinder 3, the pumping cylinder 5, the hopper 9, the S-tube valve 8, the mixer 12 and the concrete cylinder 19 into an integrated pumping device.

[0037] Wherein, pumping hydraulic cylinder 3 refers to the use of hydraulic oil as the working medium of the cylinder, which can be implemented by a double-acting hydraulic cylinder. Pump feeding cylinder 5 refers to a cylindrical container for containing and transporting materials, which can be implemented by a cylindrical structure made of wear-resistant alloy steel material. S pipe valve 8 refers to a valve device for controlling the flow direction of the material, which can be implemented by a swing type S pipe structure driven by hydraulic pressure. Hopper 9 refers to a container for storing the material to be pumped, which can be implemented by a conical or funnel-shaped metal structure. Concrete cylinder 19 refers to a cylindrical container for temporarily storing and mixing materials, which can be implemented by a steel cylinder with an internal mixing device. Mixer 12 refers to a device for thoroughly mixing materials, which can be implemented by a static or dynamic mixer. Truss 1 refers to a frame structure for supporting and connecting various components, which can be implemented by a welded or bolted steel structure.

[0038] The core innovation of the present application is to replace the traditional hose pump with a hydraulic pumping system, and to integrate the pumping, mixing and mixing system into one whole through truss 1. The hydraulic pumping system can provide enough power to overcome the high viscosity of the foam polymer soil, solving the problem of difficult pumping. At the same time, the integrated design optimizes the space utilization and reduces the floor area of the device. The working principle of the present application is as follows: pumping hydraulic cylinder 3 is connected to one side of pump feeding cylinder 5 through the telescopic cylinder rod. Pumping hydraulic cylinder 3 adopts a double-acting hydraulic cylinder structure, which can produce reciprocating motion. Pump feeding cylinder 5 is a cylindrical structure made of wear-resistant alloy steel material, with a piston inside. The other side of pump feeding cylinder 5 is connected to the bottom of hopper 9 through S pipe valve 8. S pipe valve 8 adopts a swing type S pipe structure driven by hydraulic pressure, which can control the flow direction of the material. Hopper 9 is a conical or funnel-shaped metal structure for storing the material to be pumped. Hopper 9 is connected to concrete cylinder 19 through the discharge port. Concrete cylinder 19 is a steel cylinder with an internal mixing device, used for temporarily storing and initially mixing materials. The outlet of concrete cylinder 19 is connected to mixer 12 through a pipe. Mixer 12 can be a static or dynamic mixer for thoroughly mixing materials. Truss 1 is a welded or bolted steel structure that connects pumping hydraulic cylinder 3, pump feeding cylinder 5, hopper 9, S pipe valve 8, mixer 12 and concrete cylinder 19 into a whole pumping device.

[0039] When working, the pumping hydraulic cylinder 3 pushes the piston in the pump feeding cylinder 5 to reciprocate, and the material in the hopper 9 is extracted. The S pipe valve 8 swings left and right under the hydraulic drive, and controls the material from the hopper 9 into the concrete cylinder 19. In the concrete cylinder 19, the material is preliminarily stirred and then enters the mixer 12 for full mixing, and finally is transported to the construction area. The foam polymer soil stirring and mixing pumping device of the present application selects a hydraulic pumping system instead of the existing technology of a hose pump, which can provide sufficient thrust for the pumping device to overcome the high viscosity of the foam polymer soil. The truss 1 integrated design can effectively reduce the floor area of the device and improve the space utilization. This design not only solves the pumping problem, but also optimizes the layout and efficiency of the whole system.

[0040] Please refer to Figure 1 and Figure 2 In the foam polymer soil stirring and mixing pumping device of the present application, the pumping hydraulic cylinder 3 is a key component in the concrete pumping system, which realizes the suction and pumping of the material through the reciprocating movement of the piston in the cylinder. In the specific implementation, the movement of the piston in both directions is completed by hydraulic pressure. The hydraulic oil enters from one end of the cylinder, pushes the piston to move to the other end, and thus pushes the material. When the piston reaches the end of the stroke, the hydraulic oil pressure stops the movement of the piston, completing a pumping cycle. The pumping hydraulic cylinder 3 also includes a cylinder check valve 13, which mainly controls the one-way flow of oil and prevents reverse flow. It is similar to a diode in a circuit, allowing oil to flow freely in one direction and closing in the opposite direction to prevent reverse flow. In the concrete pumping system, the pumping hydraulic cylinder 3 is usually connected in series with the cylinder check valve 13. The hydraulic oil pump pressurizes the oil through the cylinder check valve 13, and the pressurized oil is pressed into the energy accumulator 6, and the control oil enters the swing reversing valve through the hydraulic control reversing valve and the solenoid valve, controls the reversing of the cylinder, and thus realizes the alternating swing and pumping action of the pumping hydraulic cylinder 3. The function of the cylinder check valve 13 is to ensure that the hydraulic oil can only flow in one direction, prevent the reverse flow of oil during pumping, and ensure the safe and stable operation of the system. The cylinder check valve 13 is installed at the oil outlet of the hydraulic pump, which can prevent the pump from being damaged due to pressure impact when it stops, prevent the loss of oil in the system, avoid air entering the system, and ensure the normal work of the pumping hydraulic cylinder 3.

[0041] Further, in some preferred embodiments, an oil cylinder piston 17 is arranged inside the pump feeding cylinder 5, and the oil cylinder piston 17 is pushed to reciprocate by the telescopic oil cylinder rod to realize the suction and pumping of the material.

[0042] To effectively absorb and pump materials, the present invention incorporates a cylinder piston 17 within the pumping cylinder 5. A telescopic cylinder rod propels the cylinder piston 17 in reciprocating motion, achieving material absorption and pumping. This design is particularly suitable for processing low-flow, high-viscosity materials such as foamed polymer clay, overcoming the limitations of hose pumps in handling such materials. Specifically, the cylinder piston 17, located within the pumping cylinder 5, serves as the core component for pushing the material. The telescopic cylinder rod is connected to the cylinder piston 17, which reciprocates to propel the piston 17, achieving material absorption and pumping. These technical features work together to form a complete pumping system. The reciprocating motion of the telescopic cylinder rod drives the cylinder piston 17 within the pumping cylinder 5. When the cylinder piston 17 moves backward, negative pressure is created within the pumping cylinder 5, sucking in the material. When the cylinder piston 17 moves forward, pressure is applied to the material, enabling pumping. This design effectively processes foamed polymer clay with low flow rates and high viscosity, overcoming the inability of hose pumps to meet pumping requirements.

[0043] As a preferred embodiment, the oil cylinder piston 17 can be made of a material with good sealing properties, such as polytetrafluoroethylene or high-density polyethylene. These materials have good wear resistance and chemical stability, and can maintain a good sealing effect during long-term use. The diameter of the oil cylinder piston 17 can be designed according to the inner diameter of the pumping cylinder 5, and is usually 0.5-2mm smaller than the inner diameter of the pumping cylinder 5 to ensure a good sealing effect and smooth movement. In actual applications, the reciprocating frequency of the telescopic oil cylinder rod can be adjusted according to the viscosity and fluidity of the material. For example, for foamed polymer soil with a higher viscosity, the reciprocating frequency can be set in the range of 10-30 times per minute to ensure that the material has enough time to be sucked in and pumped out while maintaining a high pumping efficiency.

[0044] Compared with the prior art, the foamed polymer soil stirring and mixing pumping device of the present application forms alternating negative pressure and positive pressure in the pumping cylinder 5 through the reciprocating motion of the telescopic cylinder rod, and the cylinder piston 17 is used to suck in and pump materials, respectively, thereby achieving efficient transportation of foamed polymer soil. This pumping method can not only meet the pumping requirements of foamed polymer soil, but also improve the pumping efficiency. This design is particularly suitable for processing materials such as foamed polymer soil with small flow values ​​and high viscosity, and can overcome the limitations of hose pumps when processing such materials. Compared with traditional hose pumps, the present application can provide greater pumping pressure, is more adaptable, and can handle a wider range of material viscosities. In addition, the present design has a simple structure, is easy to maintain, has high operational reliability, and can significantly improve the production efficiency of foamed polymer soil.

[0045] Furthermore, the present application also proposes an S-tube valve driving cylinder 7, which drives the S-tube valve 8 to swing left and right to allow materials to enter the concrete cylinder 19 from the hopper 9.

[0046] Wherein, the S valve drive cylinder 7 provides driving force, drives the S valve 8 to swing left and right, and controls the flow direction of the material. The hopper 9 is used to store the material to be pumped, and the concrete cylinder 19 is used to receive the material entering from the hopper 9. The transmission process of the material from the hopper 9 to the concrete cylinder 19 is realized, the S valve drive cylinder 7 drives the S valve 8 to swing left and right, so that the S valve 8 switches between the hopper 9 and the concrete cylinder 19, thereby controlling the flow direction of the material. When the S valve 8 swings to the hopper 9, the material flows from the hopper 9 into the S valve 8; when the S valve 8 swings to the concrete cylinder 19, the material flows from the S valve 8 into the concrete cylinder 19. This left and right swinging mode can effectively control the flow of the material, ensuring that the material can smoothly enter the concrete cylinder 19 from the hopper 9.

[0047] In the specific implementation process, the S valve drive cylinder 7 provides power through the hydraulic system to drive the S valve 8 to swing left and right. By controlling the extension and retraction of the cylinder, the swing angle and speed of the S valve 8 can be accurately controlled to adapt to the flow characteristics of different materials. The hopper 9 and the concrete cylinder 19 are connected by pipes, and the swing of the S valve 8 realizes the flow switching of the material in the pipe. Further, the design of the S valve 8 can be optimized according to different material characteristics, such as adjusting the cross-sectional area and shape of its channel, to improve the flow efficiency of the material.

[0048] The S valve 8 is a distribution valve used in concrete pumping equipment, which mainly connects the arm pipe of the pump truck with the concrete delivery cylinder to realize continuous pumping of concrete, and the characteristic is that the internal liquid flows in the direction of the one-way arrow. In the pumping device, the S valve 8 realizes the suction and pumping of the material through the swing port thereof. The swing port of the S valve 8 is a plane, which is easy to adjust after wear and has good sealing performance. Through this design, the technical scheme of the present application effectively solves the technical problem of how to realize the material from the hopper 9 into the concrete cylinder 19. Compared with the prior art, the scheme of the present application has the advantages of simple structure, accurate control and strong adaptability, especially suitable for the delivery of foam polymer soil with small flow value and high viscosity, and overcomes the limitations of traditional hose pumps in handling high viscosity materials.

[0049] Further, please refer to Figure 3 The stirring motor 18 is arranged in the concrete cylinder 19 for driving the stirring blades.

[0050] The application sets a stirring motor 18 in the concrete cylinder 19, which drives the stirring blades to stir. This design can effectively improve the stirring effect of the material and ensure uniform mixing of the material. Specifically, the stirring motor 18 can use an electric motor or a hydraulic motor. The stirring blades can be designed in different shapes and angles to adapt to different viscosity and fluidity of the material. For example, spiral blades, paddle-shaped blades or grate-shaped blades can be used. The rotating speed of the stirring motor 18 can be adjusted according to the characteristics of the material, and the installation position of the stirring motor 18 can be optimized according to the structure of the concrete cylinder 19. For example, the stirring motor 18 can be installed at the top of the concrete cylinder, and the stirring blades inside the concrete cylinder 19 are driven by shaft transmission; or the stirring motor 18 is directly installed on the side wall of the concrete cylinder, and the stirring blades directly extend into the concrete cylinder.

[0051] The cooperation of the stirring motor 18 and the S-valve driving oil cylinder 7 can realize continuous stirring and pumping of the material. When the S-valve driving oil cylinder 7 drives the S-valve 8 to swing left and right, the material enters the concrete cylinder 19 from the hopper 9, and at the same time the stirring motor 18 drives the stirring blades to start working to fully stir the material entering the concrete cylinder 19. This design not only improves the stirring efficiency, but also ensures the uniformity of the material, providing a good foundation for subsequent pumping and construction.

[0052] The application solves the problem of insufficient stirring of the material by setting a stirring motor 18 in the concrete cylinder 19. The stirring motor 18 drives the stirring blades to fully stir the material entering the concrete cylinder 19 and improve the mixing uniformity. At the same time, the S-valve driving oil cylinder 7 controls the process of the material entering the concrete cylinder 19 from the hopper 9, and cooperates with the stirring motor 18 to realize continuous stirring and pumping of the material. This design not only improves the stirring efficiency, but also ensures the uniformity of the material, providing a good foundation for subsequent pumping and construction. Specifically, when the S-valve driving oil cylinder 7 drives the S-valve 8 to swing towards the concrete cylinder 19, the material begins to enter the concrete cylinder 19 from the hopper 9. The stirring motor 18 starts immediately and drives the stirring blades to start rotating. The rotating speed of the stirring blades can be adjusted according to the viscosity and fluidity of the material to ensure the best stirring effect. As the material continuously enters the concrete cylinder 19, the stirring blades continuously work to fully mix the newly entered material with the material already in the concrete cylinder 19. When the material in the concrete cylinder 19 reaches a certain amount, the pumping hydraulic cylinder 3 starts to work, and the pumping cylinder 5 pumps the uniformly stirred material to the mixer 12. During the whole process, the stirring motor 18 continuously works to ensure that the material in the concrete cylinder 19 always maintains a uniform state.

[0053] As a preferred embodiment, the stirring motor 18 can adopt variable frequency control to automatically adjust the rotating speed according to the characteristics of the material and the stirring demand. For example, when it is detected that the material has high viscosity, the rotating speed of the stirring motor 18 can be appropriately increased; when the material has good fluidity, the rotating speed can be reduced to save energy. The stirring blade can be designed to be detachable for easy cleaning and replacement. In addition, guide plates or baffles can be arranged on the inner wall of the concrete cylinder 19 to cooperate with the rotation of the stirring blade to further improve the stirring effect.

[0054] Traditional foam polymer stirring mixing and pumping devices usually rely on the natural flow of the material in the concrete cylinder 19 to achieve mixing, and the stirring effect is limited. The present application can actively stir the material by arranging the stirring motor 18 and the stirring blade in the concrete cylinder 19, which greatly improves the stirring effect and uniformity. By adjusting the rotating speed of the stirring motor 18 and the shape of the stirring blade, the device of the present application can adapt to materials with different viscosities and fluidities, and has a wider range of applications. Due to more thorough stirring, the uniformity of the material is guaranteed, reducing the rework or quality problems caused by uneven stirring, thereby improving the overall production efficiency. The present application integrates the stirring function in the concrete cylinder 19, without the need for additional stirring equipment, making the entire device structure more compact and saving space.

[0055] Further, in some preferred embodiments, a grid 16 is further included for filtering the stirred slurry.

[0056] The present application further introduces a grid 16 for filtering the stirred slurry. The design of the grid 16 can have various implementation ways. For example, the grid 16 can be arranged at the outlet of the concrete cylinder in the form of a metal grid or a perforated plate. The material of the grid 16 can be selected from stainless steel, carbon steel or other corrosion-resistant metal materials to ensure that it will not be corroded by the slurry in long-term use. The grid 16 can be designed to be detachable for easy cleaning and replacement. For example, a buckle or bolt fixing method can be used to enable the operator to quickly disassemble the grid for cleaning. The shape of the grid 16 can be planar, cylindrical or conical to adapt to different installation positions and filtering requirements. In some embodiments, the grid 16 can adopt a multi-layer design, and different layers of the grid 16 have different mesh sizes to achieve a more precise filtering effect.

[0057] The working principle of the grid 16 is to intercept large particle impurities in the slurry by physical barriers. When the mixed slurry passes through the grid 16, particles larger than the mesh or aperture will be blocked, while slurry smaller than the mesh or aperture can pass through smoothly. This can effectively remove impurities in the slurry, improve the uniformity and purity of the slurry. The grid 16 is arranged in cooperation with the stirring motor 18 and stirring blades in the concrete tank 19. The stirring motor 18 drives the stirring blades to mix the materials thoroughly, and the grid 16 plays a filtering role in the output process of the mixed slurry. This combination not only ensures the thorough mixing of the slurry, but also further improves the quality of the slurry through filtration.

[0058] The use of the grid 16 significantly improves the quality of the pumped slurry, reduces the presence of impurities and large particles, thereby avoiding the problem of blockage that may occur in the subsequent pumping process. This not only improves the pumping efficiency, but also prolongs the service life of the equipment, reduces the maintenance cost, and significantly improves the performance of the foam polymer soil mixing and pumping device. In traditional technology, impurities and large particles in the slurry often cause blockage of the pumping pipeline, which requires frequent shutdown for cleaning, affecting the construction efficiency. The grid 16 design of the present application effectively solves this problem without significantly increasing the complexity of the device. The use of the grid 16 not only improves the quality of the slurry, but also reduces the equipment failure rate, thereby improving the efficiency and reliability of the entire construction process.

[0059] Further, in some preferred embodiments, a jacking hydraulic cylinder 2 is provided on the truss 1 for lifting and lowering the pumping device.

[0060] The foam polymer soil mixing and pumping device of the present application is provided with a jacking hydraulic cylinder 2 on the truss 1 for lifting and lowering the entire pumping device. This design allows the entire device to adjust the height according to actual needs, increasing the flexibility and applicability of the device. The jacking hydraulic cylinder 2 can control the height of the entire pumping device, facilitating the docking with other equipment or adapting to different working environments. At the same time, this design is also beneficial to the transportation and storage of the equipment, which can be lowered in height when needed, improving the space utilization.

[0061] Specifically, the lifting hydraulic cylinder 2 in the foam polymer soil mixing and pumping device of the present application can have multiple implementation ways. For example, one lifting hydraulic cylinder 2 can be arranged at each corner of the truss 1, which can ensure the stable lifting of the entire device. Alternatively, two or three lifting hydraulic cylinders 2 can be arranged at appropriate positions of the truss 1 according to the weight distribution of the device. The connection mode of the lifting hydraulic cylinder 2 and the truss 1 can also have multiple options. The hinged mode can be adopted to enable the lifting hydraulic cylinder 2 to swing within a certain angle range to adapt to different terrain conditions. The fixed connection mode can also be adopted to improve the stability of the entire device. The control system of the lifting hydraulic cylinder 2 can be integrated with the control system of the entire device to realize automatic control. For example, multiple preset heights can be set, and the operator only needs to select the required height through the control panel, and the system can automatically adjust to the corresponding position. At the same time, a manual control mode can also be set to allow the operator to fine-tune the device height according to the actual situation.

[0062] In addition, the arrangement of the lifting hydraulic cylinder 2 can also have a synergistic effect with other components. For example, when cleaning or maintaining components such as the concrete tank 19 and the mixer 12, the entire device can be lifted by the lifting hydraulic cylinder 2 to facilitate the operation of the workers. This design not only improves the work efficiency, but also improves the maintenance conditions and prolongs the service life of the equipment. The control system of the lifting hydraulic cylinder 2 adopts a proportional control valve to realize precise height adjustment. The system has four preset heights: ground height, 0.5m height, 1m height and 1.5m height. The operator can directly select the required height through the buttons on the control panel, and the system will automatically adjust to the corresponding position. At the same time, the system also has a manual fine-tuning function, which can set the minimum unit of each adjustment.

[0063] To ensure safety, the present application has multiple protection mechanisms, including overload protection, synchronous control and emergency stop function. The overload protection can automatically stop the lifting operation when the weight of the device exceeds the safety value. The synchronous control ensures the synchronization of the four lifting hydraulic cylinders 2 to prevent the device from tilting. The emergency stop function allows the operator to immediately stop all actions when an abnormal situation is found. These control functions are integrated in the electric control box 11, which plays a crucial role in the foam polymer soil mixing and pumping device. It is responsible for the electrical control and monitoring of the entire device. The electric control box 11 realizes the functions of switching, adjusting and protecting the equipment or machine through electrical control. It receives external signals from sensors, switches, etc., processes them and triggers the corresponding control actions, such as the start, stop and adjustment of the hydraulic cylinder. The electric control box 11 realizes intelligent control of the pumping device, improves production efficiency and product quality, and ensures efficient, stable and safe operation of the device.

[0064] Compared with the prior art, the foamed polymer soil mixing and pumping device of the present application solves the problem of device lifting and lowering by arranging a lifting hydraulic cylinder 2 on the truss 1. This design not only improves the applicability of the device, but also improves the maintenance conditions of the equipment. Compared with devices with fixed heights, the design of the present application can better adapt to different working environments and improve work efficiency. At the same time, the adjustable height also makes the equipment more convenient during transportation and storage, saving space. In addition, the design of the present application also takes into account safety and ease of operation. Through multiple protection mechanisms and intelligent control systems, the safety and ease of use of the device during use are ensured. These improvements give the device of the present application obvious advantages in the production and application of foamed polymer soil.

[0065] Furthermore, in some preferred embodiments, an electric motor 4 is included to extract hydraulic oil from the hydraulic oil tank 10, pressurize it, and drive various components to perform work.

[0066] The foamed polymer soil mixing and pumping device of the present application includes an electric motor 4, which is used to draw hydraulic oil from a hydraulic oil tank 10, pressurize it, and then drive various components to perform work. By using the electric motor 4 as a unified power source, the pumping device's power system is centralized and highly efficient. Specifically, the electric motor 4 serves as the core power source for the entire pumping device. Connected to the hydraulic oil tank 10, the electric motor 4 rotates at high speed to draw and pressurize the hydraulic oil from the tank 10. The pressurized hydraulic oil is then delivered to various components of the pumping device, providing power support. For example, the pressurized hydraulic oil drives the movement of key components such as the pumping cylinder 3, the S-valve drive cylinder 7, and the mixing motor 18. The speed and output power of the electric motor 4 can be adjusted according to the actual needs of the pumping device. During the foamed polymer soil production process, different pumping pressures and flow rates may be required. The electric motor 4 can be dynamically adjusted through methods such as variable frequency control to adapt to different operating conditions. Preferably, the electric motor 4 can be a high-efficiency permanent magnet synchronous motor.

[0067] The present application adopts an electric motor 4 as a unified power source to provide power for all hydraulic components of the pumping device, thereby simplifying the system structure and reducing the coordination and control problems that may be caused by multiple independent power sources. The centralized power system reduces the energy conversion links and reduces transmission losses. The high efficiency characteristics of the electric motor 4 further improve the overall energy utilization efficiency. By adjusting the speed and output power of the electric motor 4, precise control of the entire system can be achieved to meet the needs of different working conditions in the production process of foamed polymer soil. Compared with decentralized power systems, centralized power sources reduce the number of components that require maintenance, simplify the maintenance process, and help reduce long-term operating costs.

[0068] Further, in some preferred embodiments, the electric motor 4 is connected with a plunger pump 14, which is the main oil pump for powering the pumping hydraulic cylinder 3.

[0069] The electric motor 4 serves as the power source, providing the basic power input for the entire system. The plunger pump 14 is the main oil pump, directly connected to the electric motor 4. The main function of the plunger pump 14 is to convert the mechanical energy generated by the electric motor 4 into hydraulic energy and direct it to the pumping hydraulic cylinder 3. By connecting the electric motor 4 with the plunger pump 14, a complete power transmission chain is formed. The mechanical energy generated by the electric motor 4 is first transmitted to the plunger pump 14, which then converts this energy into high-pressure hydraulic energy, and finally delivers it to the pumping hydraulic cylinder 3 through the pipeline. This design realizes the effective conversion and transmission of energy from electrical energy to mechanical energy, and then to hydraulic energy.

[0070] Specifically, the electric motor 4 can adopt various types, such as alternating current motor or direct current motor. The plunger pump 14 can be selected as an axial plunger pump or a radial plunger pump, with a displacement that can be adjusted between 50-200 mL / r to adapt to different pumping requirements. The connection between the electric motor 4 and the plunger pump 14 can be achieved through a shaft coupling or a belt drive. The outlet of the plunger pump 14 is connected to the pumping hydraulic cylinder 3 through a high-pressure oil pipe. By using the plunger pump 14 as the main oil pump, a high enough pressure can be generated to drive the pumping hydraulic cylinder 3, thus meeting the pumping requirements of foam polymeric soil, a material with high viscosity and low flowability. The working pressure of the plunger pump 14 can reach 20-30 MPa, much higher than that of ordinary gear pumps or vane pumps, which enables it to provide sufficient power for the pumping hydraulic cylinder 3. In addition, the efficiency of the plunger pump 14 is usually between 85-95%, much higher than that of other types of hydraulic pumps. This means that it can more effectively convert the mechanical energy of the electric motor 4 into hydraulic energy, reducing energy loss and improving the energy efficiency of the entire system. The plunger pump 14 also has good self-priming ability and anti-pollution ability, which is particularly important for handling materials such as foam polymeric soil that may contain impurities.

[0071] The present application solves the problem of providing power for the pumping hydraulic cylinder 3 through reasonable selection of components and connection methods. The electric motor 4 serves as the initial power source, and the plunger pump 14 serves as the key component for energy conversion and pressure boosting, together ensuring that the pumping hydraulic cylinder 3 can obtain sufficient power to complete the pumping task of foam polymeric soil. This design not only improves the pumping capacity of the system, but also enhances the applicability and efficiency of the entire device. The system is also equipped with pressure compensation and load sensing control, which can automatically adjust the output pressure and flow according to the pumping requirements, further improving energy efficiency and pumping performance.

[0072] Compared with the prior art, the technical scheme of the present application has obvious advantages. The traditional hose pump is difficult to produce high enough pressure to pump high viscosity foam polymer due to its structural limitations. The electric motor 4 combined with the plunger pump 14 not only can produce higher pressure, but also can provide greater flow, thereby significantly improving the pumping efficiency. In addition, the self-priming ability and anti-pollution ability of the plunger pump 14 are better than those of the hose pump, making the whole system more reliable and stable when handling materials of different properties. Compared with the system directly driven by the hydraulic motor, the combination of the electric motor 4 and the plunger pump 14 realizes more efficient energy conversion, reduces energy consumption, and prolongs the service life of the equipment.

[0073] Further, in some preferred embodiments, the plunger pump 14 is connected to the double gear pump 15 through a hydraulic pipeline, and the output ends of the double gear pump 15 are connected to the stirring motor 18 and the lifting hydraulic oil cylinder 2 respectively. The design of the double gear pump 15 can adopt different gear ratios to adapt to different working requirements. The output pressure and flow of the plunger pump 14 can be controlled by adjusting the speed of the electric motor 4, so as to realize accurate power distribution of the stirring motor 18 and the lifting hydraulic oil cylinder 2. The hydraulic oil flow between the stirring motor 18 and the lifting hydraulic oil cylinder 2 can be adjusted by adjusting the valve to ensure their coordinated work.

[0074] The technical scheme of the present application forms an efficient hydraulic power system through the combination of the plunger pump 14 and the double gear pump 15. The plunger pump 14 serves as the main power source to provide stable hydraulic oil flow, while the double gear pump 15 reasonably distributes the hydraulic oil to the stirring motor 18 and the lifting hydraulic oil cylinder 2. After obtaining sufficient power, the stirring motor 18 can effectively stir the material, improving the uniformity and quality of the material. After obtaining sufficient power, the lifting hydraulic oil cylinder 2 can stably lift the pumping device, ensuring the normal operation of the equipment. Compared with the traditional power distribution method, the scheme of the present application improves the overall efficiency and reliability of the system. Compared with the prior art, the present application realizes efficient distribution of power through the combination of the plunger pump 14 and the double gear pump 15, solving the problem of insufficient power in the traditional system. In the prior art, the hose pump cannot meet the pumping requirements of foam polymer, while the hydraulic system of the present application ensures the power supply of the stirring motor 18 and the lifting hydraulic oil cylinder 2 through reasonable design, improving the overall performance and stability of the system.

[0075] Further, in some preferred embodiments, an energy storage device 6 is further included for absorbing high-pressure hydraulic oil pumped by the electric motor 4 to drive the S valve driven oil cylinder 7 under the control of the electric control box 11.

[0076] The accumulator 6, as a key technical feature, absorbs high-pressure hydraulic oil and is controlled by the electric control box 11 to drive the S-valve drive cylinder 7, thereby effectively utilizing hydraulic energy storage and release during the pumping process of foam concrete. The accumulator 6 plays a role in ensuring sufficient energy to push the high-viscosity material from the hopper 9 to the outside for efficient pumping process.

[0077] Specifically, the accumulator 6 can be implemented in various forms, such as a hydraulic accumulator or a gas-liquid accumulator, so that the accumulator 6 can absorb and store energy when the electric motor pumps high-pressure hydraulic oil, and then release energy to drive the S-valve drive cylinder 7 when needed. When the electric motor 4 pumps high-pressure hydraulic oil, part of the hydraulic oil is stored in the accumulator 6. During this process, the piston or diaphragm inside the accumulator 6 is compressed, thereby storing energy. When it is needed to drive the S-valve drive cylinder 7, the electric control box 11 sends a signal, and the accumulator 6 releases the stored energy to push the high-pressure hydraulic oil to the S-valve drive cylinder 7 quickly, so that it can respond quickly and perform the swing action of the S-valve 8.

[0078] The use of the accumulator 6 in combination with the electric control box 11 further improves the response speed and control accuracy of the system. The electric control box 11 can accurately control the timing and intensity of energy release of the accumulator 6 according to the real-time demand during the pumping process. This intelligent control method can automatically adjust the swing frequency and amplitude of the S-valve 8 according to the viscosity change of the foam concrete, thereby achieving the optimal pumping effect. By introducing the accumulator 6, the pumping system of the present application can more effectively handle high-viscosity foam concrete. The use of the accumulator 6 not only improves the pumping capacity of the system, but also enhances the stability and reliability of the entire device. During the pumping process, even if there is a transient fluctuation in the output pressure of the electric motor 4, the accumulator 6 can provide stable energy output to ensure the continuous and smooth operation of the S-valve drive cylinder 7, significantly improving the pumping efficiency and reliability. In addition, the use of the accumulator 6 also reduces the load of the electric motor 4, prolongs the service life of the equipment, and reduces energy consumption.

[0079] In the traditional technology, the output pressure and flow of the hose pump are often insufficient to overcome the resistance of high viscosity materials, resulting in low pumping efficiency, and even plugging. The foam polymeric soil mixing and pumping device of the present application provides higher instantaneous pressure and more stable energy output through the hydraulic system, including the pumping hydraulic cylinder 3 connected to one side of the pump feeding cylinder 5 through the telescopic cylinder rod, the other side of the pump feeding cylinder 5 connected to the bottom of the hopper 9 through the S pipe valve 8, the hopper 9 connected to the concrete cylinder 19 through the discharge port, the outlet of the concrete cylinder 19 connected to the mixer 12 through the pipeline, and the truss 1 connecting and integrating the pumping hydraulic cylinder 3, the pump feeding cylinder 5, the hopper 9, the S pipe valve 8, the mixer 12 and the concrete cylinder 19 into a whole pumping device. When working, the pumping hydraulic cylinder 3 pushes the piston in the pump feeding cylinder 5 to reciprocate, and the material is extracted from the hopper 9, the S pipe valve 8 swings left and right under the hydraulic drive, controls the material to enter the concrete cylinder 19 from the hopper 9, the material is preliminarily mixed and then enters the mixer 12 through the pipeline for sufficient mixing, and finally is delivered to the construction area. The hydraulic pumping system used in the present application can generate sufficient thrust to overcome the high viscosity of the foam polymeric soil, and the truss 1 is used to integrate each part into a pumping device, which can effectively reduce the floor area of the device and improve the space utilization. Not only the pumping problem is solved, but also the layout and efficiency of the whole system are optimized.

For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
