Description
Technical Field
[0001] The utility model relates to the technical field of concrete mixing equipment, and more specifically to an all-in-one concrete mixing and pumping machine. Background Art
[0002] 3D printing concrete technology is a new type of intelligent construction technology that combines 3D printing technology with technology in the field of concrete. Its main principle is to use computers to perform 3D modeling and segmentation of concrete components to produce three-dimensional information, and then pass the prepared concrete mixture through an extrusion device, according to a set program, through mechanical control, and extrude and print through a nozzle to finally obtain a concrete component.
[0003] 3D printing concrete technology eliminates the cumbersome procedures of supporting and removing formwork during the construction process, simplifies the construction process, and greatly saves manpower. However, traditional concrete equipment such as mixers and conveyors have single functions and cannot achieve the integration and automation of the entire process of adding water, mixing, pumping, etc. during concrete 3D printing; at the same time, existing concrete mixing devices are generally large in size and difficult to move. When used, the mixed concrete needs to be manually transferred, which increases the labor intensity of workers. After the mixing is completed, the concrete will become harder if placed for a short time, thus affecting the quality of 3D printed concrete.
[0004] Therefore, how to provide a concrete mixing and pumping machine that can integrate the mixing and pumping mechanisms of 3D printed concrete, automate the process, reduce labor intensity, and improve the quality of 3D printing is a problem that technical personnel in this field urgently need to solve.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A concrete mixing and pumping integrated machine, comprising:
[0008] A frame, wherein a travel wheel is installed at the bottom of the frame;
[0009] A stirring mechanism, the stirring mechanism comprising a stirring barrel and a driving assembly, the stirring barrel being mounted on the frame via a bracket, the driving assembly being in driving connection with a stirring shaft in the stirring barrel and capable of driving the stirring barrel to flip;
[0010] A water supply mechanism, the water supply mechanism is fixed on the frame and is located on one side of the mixing barrel, and a water outlet end of the water supply mechanism is correspondingly connected to a feed end of the mixing barrel;
[0011] A pumping mechanism, which is fixed on the frame and located below the mixing barrel, for conveying the materials mixed in the mixing barrel.
[0012] A control mechanism, which controls the operation of the drive assembly, the water supply mechanism and the pumping mechanism.
[0013] Through the above technical solutions, a concrete mixing and pumping integrated machine provided by the utility model has traveling wheels arranged at the bottom of the frame, which facilitates the movement of the device. It can be moved to a designated position according to needs. The mixing mechanism, the water supply mechanism and the pumping mechanism are integrated on the frame, enabling the integration of mixing and pumping of 3D printing concrete, reducing labor intensity.

[0064] In order to further optimize the above technical solution, the pumping mechanism 4 includes a first hopper 41, a third drive motor 42 and a grouting pump 43. The first hopper 41 is located directly below the mixing barrel 21.

[0065] In order to further optimize the above technical solution, the specific structural arrangement and related operating principle of the pumping mechanism 4 are the same as those in the prior art and will not be described in detail herein.
[0066] In order to further optimize the above technical solution, a pressure gauge 45 is provided at the discharge end of the grouting pump 43, which can measure the grouting pressure, send a control signal according to the grouting pressure value, and feed it back to the control mechanism to automatically control the rotation speed of the third drive motor 42 to control the pumping flow rate, and can automatically adjust the grouting pressure of the equipment to prevent the internal pressure of the pumping mechanism from being too high, thereby causing hidden dangers such as pipe burst; the rotation speed of the third drive motor 42 can be manually set through the operation panel or controlled by the control mechanism or an external 3D concrete printing robot, so as to coordinate the pumping material speed with the printing speed and realize the automation of the printing process.

[0068] In order to further optimize the above technical solution, a housing 5 is fixed to the outer side of the frame 1, and a display screen 51 and an operation panel 52 are installed on the housing 5. The display screen 51 and the operation panel 52 are both electrically connected to the control mechanism.
[0069] To further optimize the above technical solution, the rack 1 includes an upper rack body 12 and a lower rack body 13. The stirring mechanism 2 and the water supply mechanism 3 are installed on the upper rack body 12, and the pumping mechanism 4 is installed on the lower rack body 13.
[0070] To further optimize the above technical solution, a feeding mechanism 6 is further included. One end of the lower rack body 13 has an extension plate 14 extending outward therefrom, and the feeding mechanism 6 is installed on the extension plate 14. The feeding mechanism 6 includes a bottom plate 61, a vertical rod 62, and a second hopper 63. The bottom plate 61 is fixed to the rack 1 and is located on the side of the mixing barrel 21 away from the water supply mechanism 3. The bottom end of the vertical rod 62 is slidably connected to the bottom plate 61, and the second hopper 63 is slidably connected to the vertical rod 62 through a connecting plate 64. The top end of the second hopper 63 is provided with a feeding port 631, and the bottom end has a discharge port, which is correspondingly communicated with the feeding end of the mixing barrel 21.
[0071] To further optimize the above technical solution, the movement of the vertical rod 62 on the bottom plate and the movement of the second hopper 63 on the vertical rod 62 can be driven by a common driving mechanism to drive the movement of the vertical rod and the second hopper, such as a motor driving a lead screw to drive the vertical rod 62 or the second hopper 63, or other transmission methods can also be used. This transmission method is prior art, and its structural setting and operating principle are the same as those of the prior art, so it will not be elaborated here.
[0072] To further optimize the above technical solution, a dust-proof cover 65 is fixed to the outside of the second hopper 63, and the inner diameter of the bottom opening of the dust-proof cover 65 is larger than the feeding end of the mixing barrel 21.
[0073] To further optimize the above technical solution, a weight sensor is installed on the second hopper 63. The weight sensor can display the weight of the second hopper 63 on a display screen, and the control mechanism can automatically add water in proportion according to the weight to achieve automatic setting and improve the mixing quality.
[0074] To further optimize the above technical solution, such as Figures 7-8As shown in the figure, the top of the second hopper 63 is a feeding port, where there is a cover plate 66. The bottom is hinged with a first valve 67 and a second valve 68. On both sides of the first valve 67 and the second valve 68, there are fixed a first side plate 671 and a second side plate 681 respectively. At one end of the first side plate 671 away from the first valve 67, there is fixed a third gear 672. At one end of the second side plate 681 away from the second valve 68, there is fixed a fourth gear 682. The fourth gear 682 meshes with the third gear 672. On the connecting plate 64, there is fixed an electric push rod 69. The telescopic end of the electric push rod 69 is connected to the first side plate 671. When the telescopic end of the electric push rod 69 fully extends, the first valve 67 and the second valve 68 are butted and in a closed state. When it is necessary to pour the materials in the second hopper 63 into the mixing barrel 21, control the telescopic end of the electric push rod 69 to retract, drive the first side plate 671 to open, and then drive the second side plate 681 to open through the third gear 672 and the fourth gear 682, realizing the separation of the first valve 67 and the second valve 68 and being in an open state. After the material pouring is completed, control the telescopic end of the electric push rod 69 to extend, drive the first side plate 671 to move in the reverse direction, and finally realize the butting of the first valve 67 and the second valve 68 to achieve closure.
[0075] To further optimize the above technical solution, it further includes a U-shaped baffle 683. The middle plate of the U-shaped baffle 683 is fixed on the bottom wall of the second valve 68 and partially extends to the outside of the second valve. The two side walls of the U-shaped baffle 683 are respectively located outside the first side plate 671 and the second side plate 681. The purpose of this structural setting is that when the first valve 67 and the second valve 68 are in a closed state, the middle plate of the U-shaped baffle 683 is simultaneously located below the first valve 67 and the second valve 68, which can effectively prevent material leakage. Because it is fixedly connected to the second valve 68, during the process of the second side plate 681 driving the second valve 68 to open, the U-shaped baffle 683 is simultaneously opened with the second valve 68. When closed, the middle plate of the U-shaped baffle 683 is again located below the first valve 67 and the second valve 68, covering the gap when the first valve 67 and the second valve 68 are butted.
[0076] As Figure 9 shown in the figure, when the device is used outdoors and is not restricted by the site, the above feeding mechanism may not be adopted for feeding, and feeding can be carried out through an external feeder 7. The feeder 7 is located on one side of the frame 5 and is directly mounted above the feeding end of the mixing barrel 21 through a discharge pipe 8, and the materials (printing material dry powder / cement dry powder) are put into the mixing barrel 21. A dust-proof sleeve 9 is provided between the discharge pipe 8 and the feeding end above the mixing barrel 21, which can solve the problem of dust flying during the material feeding process.
[0077] As Figure 2 shown in the figure, the operation panel 52 can adjust various parameter settings of the mixing mechanism, the water supply mechanism, the pumping mechanism and the feeding mechanism, including but not limited to the following contents:
[0078] Water supply, water injection, jogging, and stopping of the water supply mechanism; grouting, stopping, pressure relief, and speed control knob of the pumping mechanism; jogging / continuous switching knob, forward rotation, reverse rotation, and stopping of the stirring mechanism; jogging / continuous switching knob, tilting, resetting, and stopping of the mixing barrel; feeding, resetting, opening, and closing of the feeding mechanism; and there are also three buttons for lighting, emergency stop, and cleaning as additional functions.
[0079] The display screen is a touch screen and can adjust all parameters, such as the feeding height, stirring time, water supply volume, etc.; a temperature and humidity sensor is also installed outside the enclosure, and the temperature and humidity sensor is electrically connected to the control mechanism to monitor the temperature and humidity of the external environment in real time.
[0080] When the ambient temperature is on the high side, the water-cement ratio becomes smaller, the fluidity of the concrete becomes worse, and the printing speed is relatively slow; at this time, through the adjustment of the control mechanism, the speed of the pumping mechanism 4 is slowed down to adapt to the printing speed, and at the same time, the water flow value output by the water supply mechanism 3 is correspondingly increased, and the stirring time of the stirring mechanism 2 is also correspondingly lengthened; when the ambient humidity is on the high side, the water-cement ratio becomes larger, the fluidity of the concrete is large but the strength is low, and it is easy to collapse, and the printing speed is accelerated; at this time, through the adjustment of the control mechanism, the speed of the pumping mechanism 4 is increased to adapt to the printing speed, the water flow value output by the water supply mechanism 3 is correspondingly decreased, and the stirring time of the stirring mechanism 2 is also correspondingly shortened.
[0081] When the temperature is on the high or low side, the signal of the temperature sensor is processed by the processor operation and then a control signal is sent to control the water injection volume and stirring time, and at the same time, it is also output to the robotic arm control system to adjust the printing speed of the robotic arm, and the humidity control is the same; in addition, the printing program can also directly control the start and stop of the device and the pumping speed; it can adjust the water-cement ratio and printing speed in real time according to the environmental state, reduce the influence of environmental factors on the concrete state, and improve the printing quality.
[0082] The implementation mode of the present utility model is:
[0083] In the initial state, the feeding end of the mixing barrel 21 is arranged upward. Add materials (printing material dry powder / cement dry powder) into the second hopper 63. Drive the second hopper 63 to rise in the vertical direction of the vertical rod 62. When it rises to the specified safe height, drive the vertical rod 62 to move along the bottom plate 61 towards the mixing barrel 21 until it is above the feeding end of the mixing barrel 21. Drive the position of the second hopper 63 in the vertical direction of the vertical rod 62 so that the bottom opening of the dust-proof cover 65 outside the second hopper 63 abuts against the opening of the feeding end of the mixing barrel 21. Control the opening of the first valve 67 and the second valve 68 at the bottom of the second hopper 63 to pour the materials in the second hopper 63 into the mixing barrel 21. At the same time, the control mechanism controls the opening of the second solenoid valve 321 to quantitatively / proportionally inject the water in the water storage tank 31 into the mixing barrel 21. The first drive motor 221 rotates forward to drive the mixing shaft 24 to drive the blade agitator 241. The mixing time and the mixing operation speed can both be adjusted as needed.
