Description

Technical Field

[0001] The present invention belongs to the technical field of slope protection structures, and in particular relates to a processing device and a use method of a concrete vegetation bank protection structure based on 3D printing. Background Art

[0002] The slope protection structure is an engineering structure used to protect the stability of the slope. Its main purpose is to prevent the slope from being damaged and unstable due to natural or human factors. The Three Gorges Reservoir operates according to the "winter storage and summer flood" scheduling plan. The reservoir water level rises and falls periodically between the normal water storage level and the flood control limit water level throughout the year, forming a drawdown zone as high as 30 meters. This periodic water level drop has a huge impact on the slope vegetation. When the water level drops, the slope soil is washed and eroded by the water flow, resulting in soil loss and exposure of vegetation roots, further exacerbating the fragility of the vegetation. In addition to the periodic water level drop, wave erosion is also an important factor affecting the ecology of the slope vegetation in the drawdown zone of the Three Gorges Reservoir. During the water storage period, the water flow in the reservoir area is relatively fast, and the waves directly impact the slope vegetation, causing plant leaves, branches and even the entire plant to be washed away, seriously affecting the coverage and biomass of the vegetation. Wave erosion will also loosen the slope soil, reducing the soil's anti-erosion performance, further exacerbating soil erosion and vegetation destruction. The structure of the existing slope protection project is relatively primitive. It is suitable for ordinary rivers without much problem. However, it is suitable for the reservoir dam section with fast flow velocity and large water level periodic changes. There is an obvious problem of poor safety. Therefore, it is necessary to design a more sophisticated internal structure of the bank protection project and use more advanced materials for the construction of the bank protection project. In order to reduce the construction period and operation difficulty, the use of 3D printing technology to carry out this process is a relatively cutting-edge technology. However, this type of bank protection project requires a huge amount of construction and a lot of materials. A lot of time is wasted when mixing the materials, and the uniformity of the material mixing also greatly affects the quality of the subsequent construction project. Therefore, it is necessary to design a processing device and a method for using a concrete vegetation bank protection structure based on 3D printing to solve the above problems. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a processing device and a use method of a concrete vegetation revetment structure based on 3D printing. The device is intended to quickly and evenly mix a large number of 3D printed materials required for revetment projects, thereby improving the mixing efficiency and mixing effect, providing better engineering quality for the specially designed revetment project structure printed by 3D printing, and solving the problems of low material mixing efficiency and poor mixing uniformity in the prior art.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: A processing device for a concrete vegetation revetment structure based on 3D printing comprises a printing device of a frame structure, on which a feed barrel is arranged; a rotating rod is rotatably connected inside the feed barrel, the top end of the feed barrel is connected to a first motor, and the output shaft of the first motor is connected to the top end of the rotating rod; a first circular ring is slidably connected to the outer surface of the rotating rod, a second circular ring is fixedly connected to the outer wall of the first circular ring, and a third circular ring is fixedly connected to the outer wall of the second circular ring; a filter frame of a cylindrical structure is fixedly connected to the bottom end of the third circular ring, and the surface of the filter frame is a mesh structure; a plurality of rotating rods are circumferentially distributed at the bottom of the filter frame, and a mixing roller is fixedly connected to the outer wall of the rotating rod; the bottom of the rotating rod is rotatably connected to the bottom of the filter frame, and the top of the rotating rod extends from the gap between the second circular ring and the third circular ring; a lifting mechanism is arranged inside the feed barrel to cooperate with the rotating rod.

[0005] Furthermore, by controlling the first ring to slide on the rotating rod, the second ring and the third ring can be controlled to slide at the same time. There is a gap between the first ring and the second ring, and there is a gap between the second ring and the third ring. Therefore, when the first ring, the second ring and the third ring move inside the feed barrel, the material in the feed barrel will be divided through the gap between each other. Through the movement of the first ring, the second ring and the third ring, the material at the bottom can be effectively pushed up, and the material at the top can be pushed down, which can effectively improve the mixing effect and improve the final quality of the slope protection structure.

[0006] Furthermore, by means of a filter frame arranged at the bottom of the third circular ring, when the first circular ring, the second circular ring and the third circular ring move upward inside the feed barrel, the material passing through the gaps between each other can be intercepted, and the larger particles of material can be blocked to ensure the quality of the output particles and further improve the quality of the slope protection structure. At the same time, when the first circular ring, the second circular ring and the third circular ring move inside the feed barrel, the material inside the feed barrel can be effectively stirred and mixed by means of a plurality of rotating rods equipped with mixing rollers.

[0007] Furthermore, by starting the first motor, the rotating rod can be driven to rotate inside the feed barrel, and by controlling the forward and reverse rotation of the first motor, the forward and reverse rotation of the rotating rod can be controlled.

[0009] Furthermore, through the reciprocating rotation of the reciprocating screw, the transmission block can be driven to slide back and forth up and down on the outer wall of the reciprocating screw. Since one end of the transmission block is in contact with the inner wall of the feed barrel, when the reciprocating screw rotates, it will not drive the transmission block to rotate, thereby ensuring that the transmission block can only slide back and forth up and down inside the feed barrel.

[0010] Preferably, a driving wheel is fixedly connected to the outer wall of the rotating rod, a driven wheel is fixedly connected to the outer wall of the reciprocating screw rod, and the driving wheel and the driven wheel are connected to form a transmission structure through a belt.

[0014] Furthermore, when the shaft rotates, the stirring blade arranged on the shaft will rotate and cut the material in the filter frame, which can effectively break up the larger particles of material in the filter frame, and when the first ring, the second ring and the third ring slide downward inside the feed barrel, the resistance given by the material below will also lift up the material that has fallen on the bottom of the filter frame, making it easier for the stirring blade to break it up, thereby further improving the material mixing effect.

[0015] Preferably, a rotating ring is rotatably connected inside the filter frame, and a first gear ring is provided on the inner wall of the rotating ring to mesh with first gears connected to the outer surfaces of the plurality of rotating shafts.

[0016] Furthermore, when the rotating ring rotates, it will drive the first gear to rotate under the action of the first gear ring. Therefore, when the rotating ring rotates, it will drive multiple first gears to rotate, so that multiple rotating shafts drive the stirring blades to crush the material in the filter frame.

[0017] Preferably, a second motor is connected to the top end of the second ring, and an output shaft of the second motor is connected to the top end of a rotating shaft.

[0018] Furthermore, the second motor only needs to be connected to one of the rotating shafts and only needs to drive one of the first gears to rotate, and then, with the cooperation of the first gear ring, the rotating ring can be driven to make multiple rotating shafts rotate synchronously.

[0019] Preferably, a second gear ring is disposed on the outer wall of the rotating ring, and a second gear is sleeved on the outer walls of the plurality of rotating rods, and the second gear ring is meshed with the second gear.

[0020] Furthermore, when the rotating ring rotates, it will drive the second gear ring to rotate, and at this time the second gear will drive the rotating rod to rotate, thereby cooperating with the mixing roller to mix the materials in the feed barrel.

[0021] Preferably, the diameter of the second ring is greater than the diameter of the first ring, and the diameter of the third ring is greater than the diameter of the second ring.

[0022] Preferably, the method for using the processing device of the concrete vegetation revetment structure based on 3D printing comprises the following steps: S1, feeding the material to be printed into the feed barrel; S2, start the first motor to drive the rotating rod to rotate, at this time, the driving wheel drives the driven wheel to rotate under the action of the transmission structure, and the driven wheel drives the reciprocating screw to rotate, so that the transmission block supports the third ring to rise, and the third ring links the first ring and the second ring to rise together or fall with gravity; the material in the feed barrel is divided through the gaps between the three rings; S3, start the second motor to drive one of the rotating shafts to rotate, and through the cooperation of the first gear and the first gear ring, drive the rotating ring to make multiple rotating shafts rotate synchronously, and the stirring blade arranged on the rotating shaft rotates and cuts the material in the filter frame to crush the larger particles of material in the filter frame; the rotating ring simultaneously drives the second gear ring to rotate, thereby linking the second gear to drive the rotating rod to rotate, and the material in the feed barrel is mixed by the mixing roller to complete the mixing of the materials.

[0023] The beneficial effects of the present invention are as follows: In this device, the first motor drives the rotating rod to rotate. At this time, the active wheel drives the driven wheel to rotate under the action of the belt, and the driven wheel drives the reciprocating screw to rotate, so that the transmission block drives the first ring, the second ring and the third ring to slide back and forth up and down, and divides the material in the feed barrel through the gap between them.

[0038] Furthermore, when the rotating shaft 10 rotates, the stirring blade 29 arranged on the rotating shaft 10 will rotate and cut the material in the filter frame 16, which can effectively break up the larger particles of material in the filter frame 16, and when the first ring 19, the second ring 20 and the third ring 21 slide downward inside the feed barrel 8, the resistance given by the material below will also lift up the material that has fallen on the bottom of the filter frame 16, making it easier for the stirring blade 29 to break it up, thereby further improving the material mixing effect.

[0047] Embodiment three: The present embodiment provides a concrete vegetation revetment structure based on 3D printing, which is printed using the processing device of the concrete vegetation revetment structure based on 3D printing of the present invention. The structure includes a slope protection brick 1, and an extended retaining brick 2 is arranged on the top of the slope protection brick 1. The size of the extended retaining brick 2 is half of the slope protection brick 1. The interiors of the slope protection brick 1 and the extended retaining brick 2 are both cavity settings. The inner walls of the slope protection brick 1 and the extended retaining brick 2 are both provided with a first water inlet 6, and the outer walls of the slope protection brick 1 and the extended retaining brick 2 are both provided with a water outlet 31. The interior of the slope protection brick is a vegetation space filled with a cement-based habitat substrate 32.

[0048] Furthermore, when the slope protection brick 1 is installed, one side of the extended retaining brick 2 will be arranged toward the place close to the water level. When water impacts the plants on the slope protection, the extended retaining brick 2 can block the impact force of the water, which can effectively reduce the damage caused by the water impact to the vegetation.

[0049] Furthermore, when the water level exceeds the extended retaining brick 2, the water will enter the interior of the slope protection brick 1 and accumulate. At this time, the water can be introduced into the slope protection brick 1 and the interior of the extended retaining brick 2 through the opened first water inlet 6, and then discharged through the water outlet 31, which can effectively solve the problem of water exceeding the extended retaining brick 2 and accumulating in the slope protection brick 1, and the problem of long-term blistering leading to the death of vegetation.

[0050] Preferably, a second water inlet 5 is provided on the outer wall of the slope protection brick 1 away from the extended retaining brick 2, a permeable retaining column 3 is arranged inside the slope protection brick 1, and a permeable hole 4 is provided on the outer wall of the permeable retaining column 3, and the permeable retaining column 3 is connected to the inner cavity of the slope protection brick 1.

[0051] Furthermore, the slope protection bricks 1 are installed so that the second water inlet 5 fits the water outlet 31. Therefore, part of the water discharged from the water outlet 31 will flow downward through the two sides of the slope protection bricks 1 and be discharged, and part of the water will enter the permeable retaining column 3 and finally be discharged through the water outlet 31. The permeable holes 4 opened on the permeable retaining column 3 can also be used to irrigate the vegetation inside the slope protection bricks 1. When the water level is low, water can be poured in from the second water inlet 5 opened on the topmost slope protection brick 1. The water will flow downward step by step and irrigate the vegetation inside all the slope protection bricks 1, saving time and improving efficiency. At the same time, through the setting of the permeable retaining column 3, the vegetation can also be fixed and limited.

[0052] The production principle of the 3D printing-based concrete vegetation revetment structure is as follows: When the first motor 9 drives the rotating rod 17 to rotate, the driving wheel 11 will drive the driven wheel 12 to rotate under the action of the belt, and the driven wheel 12 will drive the reciprocating screw 13 to rotate, so that the transmission block 14 drives the first ring 19, the second ring 20 and the third ring 21 to slide back and forth up and down, and divide the material in the feed bucket 8 through the gap between them. Subsequently, the second motor 15 drives one of the first gears 28 to rotate, and can drive the rotating ring 25 to make multiple rotating shafts 10 rotate synchronously with the cooperation of the first gear ring 27, and the stirring blade 29 arranged on the rotating shaft 10 will rotate and cut the material in the filter frame 16, which can effectively crush the larger particles of material in the filter frame 16. At the same time, when the rotating ring 25 rotates, it will drive the second gear ring 26 to rotate, and the second gear 24 will drive the rotating rod 22 to rotate, thereby cooperating with the mixing roller 23 to mix the material in the feed bucket 8, thereby improving the mixing effect and improving the final quality of the slope protection structure.

[0053] The extended retaining brick 2 can block the impact force of water and effectively reduce the damage to vegetation caused by water impact. The water level that exceeds the extended retaining brick 2 will accumulate inside the slope protection brick 1. At this time, the water can be introduced into the slope protection brick 1 and the extended retaining brick 2 through the opened first water inlet 6, and then discharged through the water outlet 31, which can effectively solve the problem of water exceeding the extended retaining brick 2 and accumulating in the slope protection brick 1, and the long-term blistering leading to the death of vegetation.
