Description

Technical Field

[0001] This utility model relates to the field of mixing devices, specifically a 3D printed concrete raw material mixing device. Background Technology

[0002] 3D printing is an additive manufacturing technology that creates three-dimensional objects by stacking materials layer by layer based on digital models. With the continuous advancement of technology, the accuracy, speed and efficiency of 3D printing will continue to improve, enabling the creation of more complex and intricate objects.

[0003] 3D printed concrete raw materials are typically composed of concrete, admixtures, aggregates, additives, and water. Mixing these components ensures that the 3D printed concrete raw materials are homogeneous and meet the requirements for their use.

If too much of the mixed 3D printing concrete raw material is discharged, it is easy to waste the 3D printing concrete raw material after mixing, which is not conducive to the use of the mixing device.

[0005] Therefore, we propose a 3D-printed concrete raw material mixing device. Utility Model Content

[0032] Please see Figures 1-4 In this embodiment of the present invention, a 3D printing concrete raw material mixing device includes a mixing cylinder 1. A feeding hopper 2 is fixedly installed at the lower end of the mixing cylinder 1, and a feeding pipe 3 is fixedly installed at the lower end of the feeding hopper 2. A fixing plate 6 is fixedly installed on the upper surface of the mixing cylinder 1. A first rotating cylinder 7 is rotatably installed in the middle of the lower surface of the fixing plate 6.

The outer sides of the rotating spiral plate 9 are matched and fitted with corresponding positions on the inner ring surface of the mixing cylinder 1. A lifting rod is slidably inserted into the inner side of the first rotating cylinder 7 in the vertical direction. 10. A stop block 11 is fixedly installed at the lower end of the lifting rod 10. The bottom of the outer side of the stop block 11 is in a matching and fitting state with the bottom of the inner side of the hopper 2. The lifting rod 10 can easily drive the stop block 11 to move up and down, which helps to easily open and seal the bottom of the hopper 2. When in use, it helps to discharge and stop the 3D printing concrete raw material after mixing in a timely manner, which can avoid discharging too much 3D printing concrete raw material after mixing, so as to prevent waste of 3D printing concrete raw material after mixing, and facilitate the use of this mixing device.

[0033] The upper end of the first rotating cylinder 7 passes through the upper and lower surfaces of the middle part of the fixed disk 6. The upper end of the outer ring surface of the first rotating cylinder 7 is rotatably connected to the middle part of the fixed disk 6 through a bearing. The fixed disk 6 can limit the first rotating cylinder 7, which facilitates stable rotation of the first rotating cylinder 7. A second rotating cylinder 8 is fixedly mounted on the upper surface of the first rotating cylinder 7. A first pulley 15 is fixedly sleeved on the upper end of the outer ring surface of the second rotating cylinder 8. A rotating motor 18 is installed in the middle of one side of the upper surface of the fixed disk 6. The fixed disk 6 can fix and limit the rotating motor 18. The output shaft of the rotating motor 18 faces upward. A second pulley 16 is installed on the upper end of the output shaft of the rotating motor 18. A matching transmission belt 17 is sleeved between the outer sides of the first pulley 15 and the second pulley 16. The transmission belt 17 can transmit power between the first pulley 15 and the second pulley 16.

[0034] A feed hole 19 is provided in the middle of the fixed plate 6 on the side away from the rotating motor 18. The feed hole 19 penetrates the upper and lower surfaces of the fixed plate 6 at the corresponding position. Fixing rods 12 are fixed on both sides of the edge of the upper surface of the fixed plate 6. The fixed plate 6 can fix and limit the fixing rods 12, which facilitates the stable use of the fixing rods 12. The fixing rods 12 are all in a vertical state. A fixing plate 13 is fixed together at the upper end of the fixing rods 12. The fixing plate 13 is in a horizontal state. The fixing rods 12 can fix and limit the fixing plate 13, which helps to stabilize the use of the fixing plate 13.

[0035] A hydraulic cylinder 14 is installed in the middle of the upper surface of the fixed plate 13. The output rod of the hydraulic cylinder 14 faces downward and passes through the upper and lower surfaces of the middle part of the fixed plate 13. The lower end of the output rod of the hydraulic cylinder 14 is fixedly connected to the upper end of the lifting rod 10. The hydraulic cylinder 14 helps to drive the lifting rod 10 to move in the vertical direction. A mounting frame 4 is fixed at the lower end of the outer side of the outer ring surface of the mixing cylinder 1. Bolts 5 are threaded into the four corners of the mounting frame 4 in the vertical direction. The bolts 5 pass through the upper and lower surfaces of the corresponding positions on the mounting frame 4. The bolts 5 can install and limit the mounting frame 4, which facilitates the stable use of the mounting frame 4.

[0036] The working principle of this utility model is as follows: During use, the lower surfaces of the four corners of the mounting frame 4 are respectively aligned with the corresponding positions on the external 3D concrete printing equipment, and the bottom of the feeding pipe 3 is aligned with the feeding port on the external 3D concrete printing equipment. Furthermore, the mounting frame 4 is installed with the corresponding positions on the external 3D concrete printing equipment using bolts 5. The bolts 5 can fix and limit the mounting frame 4, facilitating stable use of the mounting frame 4. The mounting frame 4 can support and limit the mixing cylinder 1 and the various components assembled on the mixing cylinder 1, which helps to stabilize the use of the mixing cylinder 1 and the various components assembled on the mixing cylinder 1. The mixing cylinder 1 can support and limit the fixed plate 6 and the various components assembled on the fixed plate 6, which facilitates stable use of the fixed plate 6 and the various components assembled on the fixed plate 6.

[0037] The concrete, admixtures, aggregates, additives, and water in the 3D printing concrete raw material to be mixed are placed into the feed hole 19 on the fixed plate 6 in a certain proportion, so that the concrete, admixtures, aggregates, additives, and water in the 3D printing concrete raw material enter the mixing cylinder 1 and the discharge hopper 2 through the feed hole 19 on the fixed plate 6. The baffle 11 can block the bottom of the discharge hopper 2 to prevent leakage of the concrete, admixtures, aggregates, additives, and water in the 3D printing concrete raw material in the mixing cylinder 1 and the discharge hopper 2. After the 3D printing concrete raw material enters the mixing cylinder 1, it will flow and tumble downwards along the rotating spiral plate 9 to mix the concrete, admixtures, aggregates, additives, and water in the 3D printing concrete raw material. When it is necessary to stir and mix the concrete, admixtures, aggregates, additives, and water in the 3D printing concrete raw material, the rotating motor 18 on the upper surface of the fixed plate 6 is turned on. The fixed plate 6 can fix and limit the rotating motor 18, which helps to stabilize the use of the rotating motor 18.

[0038] With the rotating motor 18 in the open state, the output shaft of the rotating motor 18 can drive the second pulley 16 to rotate. When the second pulley 16 rotates, it can drive the first pulley 15 to rotate through the transmission belt 17. When the first pulley 15 rotates, it can drive the second rotating cylinder 8 to rotate. When the second rotating cylinder 8 rotates, it can drive the first rotating cylinder 7 to rotate along the fixed disk 6. The fixed disk 6 can limit the rotation of the first rotating cylinder 7, so as to stabilize the rotation of the first rotating cylinder 7. When the first rotating cylinder 7 rotates, it can drive the rotating spiral plate 9 to rotate. When the rotating spiral plate 9 rotates, it can stir the 3D printed concrete raw material in the mixing cylinder 1, so that the concrete, admixtures, aggregates, additives and water in the 3D printed concrete raw material are turned over along the rotating spiral plate 9, so as to mix and mix the concrete, admixtures, aggregates, additives and water in the 3D printed concrete raw material, so that the concrete, admixtures, aggregates, additives and water in the 3D printed concrete raw material are in a uniform mixed state.

[0039] When it is necessary to discharge the 3D printing concrete raw material mixed in the mixing cylinder 1 and the feeding hopper 2, the hydraulic cylinder 14 on the upper surface of the fixed plate 13 is opened. When the hydraulic cylinder 14 is open, the output rod of the hydraulic cylinder 14 can drive the lifting rod 10 to move upward. When the lifting rod 10 moves upward, it can drive the stop block 11 to move upward, so that the stop block 11 can remove the blockage on the bottom of the feeding hopper 2. After the stop block 11 removes the blockage on the bottom of the feeding hopper 2, the 3D printing concrete raw material in the mixing cylinder 1 and the feeding hopper 2 will be discharged through the bottom of the feeding hopper 2 and the feeding pipe 3, so that the mixed 3D printing concrete raw material is discharged to the feeding port of the external 3D concrete printing equipment, thereby completing the discharge of the 3D printing concrete raw material after the mixing device has been mixed. The hydraulic cylinder 14 and the lifting rod 10 can easily drive the stop block 11 to move up and down, which helps to easily open and seal the bottom of the feeding hopper 2.

[0040] During use, it helps to discharge and stop the mixing of 3D printing concrete raw materials in a timely manner, avoiding excessive discharge of the mixed 3D printing concrete raw materials and preventing waste of the 3D printing concrete raw materials after mixing, so as to facilitate the use of this mixing device.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
