Description

Technical Field

[0001] This invention relates to the field of simulated lunar soil preparation technology, and in particular to an automatic apparatus for preparing simulated lunar soil. Background Technology

[0002] Currently, my country's lunar exploration program has achieved remarkable results, and research on the moon is progressing rapidly. Given the scarcity of real lunar regolith resources, the preparation of simulated lunar regolith is particularly important. The initial intention behind this initiative is that these simulated lunar regoliths are urgently needed as a research foundation for lunar construction research. Simultaneously, these simulated lunar regoliths can also create a simulated lunar environment on Earth, providing valuable conditions for the development of lunar robots. Preparing simulated lunar regolith on Earth can provide researchers with a vast number of samples suitable for research. Under simulated lunar environmental conditions, researchers can explore the physical and chemical properties of lunar regolith, investigate its changes under different conditions, and thereby gain a deeper understanding of the moon's evolutionary history and geological characteristics.

[0003] However, most current simulated lunar soil preparation devices employ a step-by-step approach: first, drying raw materials such as volcanic ash is done using drying equipment; then, the dried material is crushed in a crusher; and finally, the material is ground to obtain the final simulated lunar soil. These steps are performed by different devices, requiring manual transfer between them. This not only results in low automation and difficulty in ensuring preparation efficiency but also risks contaminating the simulated lunar soil during transport. Therefore, we propose an automated simulated lunar soil preparation device. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0045] Example 1

[0046] Reference Figure 1-22 An automatic preparation device for simulated lunar soil includes a preparation shell 1. The inner side of the preparation shell 1 is equipped with a conveying mechanism, a drying mechanism, a crushing mechanism, and a ball milling mechanism. The conveying mechanism and the crushing mechanism are located above the drying mechanism and the ball milling mechanism, respectively. The conveying mechanism is used to convey materials, the drying mechanism is used to dry materials, the crushing mechanism is used to crush materials, and the ball milling mechanism is used to grind materials.

[0047] The conveying mechanism includes a raw material inlet funnel 2, a connecting funnel 3, a collecting funnel 4, and a conveying assembly. The raw material inlet funnel 2 is fixed to the top of the inner side of the preparation shell 1, and the connecting funnel 3 is connected to the bottom of the raw material inlet funnel 2. The collecting funnel 4 is provided on one side of the raw material inlet funnel 2 and is fixed to the inner side of the preparation shell 1. A conveying assembly is assembled between the connecting funnel 3 and the collecting funnel 4. The function of the raw material inlet funnel 2 is to receive the material and send it to the first spiral conveyor 5 below, and then to the connecting funnel 3 via the first spiral conveyor 5. The function of the connecting funnel 3 is to collect the material after it has been dried by the blower and send it to the second spiral conveyor 6 below. When the material is crushed, it will spill out from the small holes around the crushed part. The function of the collecting funnel 4 is to collect the crushed material and let it flow into the ball mill container 43 below through the circular outlet below. This outlet is strictly aligned with the inlet of the ball mill container 43 below.

[0048] The conveying assembly includes a first spiral conveyor 5 and a second spiral conveyor 6. The first spiral conveyor 5 is installed inside the raw material inlet funnel 2, and the second spiral conveyor 6 is installed at the bottom inside the connecting funnel 3. The output end of the second spiral conveyor 6 is connected to the top of the collecting funnel 4. The function of the second spiral conveyor 6 is to transport the material after it has been dried by the blower to the crushing mechanism in the upper right for crushing. This part consists of three continuous conveying devices, which are spiral conveyors, and need to complete the transportation from low to high.

[0049] The drying mechanism includes an outer shell 7, an outer shell cover 8, a turntable 12, a blower 14, a raw material inlet 16, an air inlet 17, and an air outlet 18. The outer shell 7 is located inside the funnel 3. The outer shell cover 8 is fixed to the top of the outer shell 7. The turntable 12 is installed inside the outer shell 7. The top of the outer shell cover 8 has a raw material inlet 16, an air inlet 17, and an air outlet 18. The blower 14 is fixed to the top of the outer shell cover 8. The output end of the blower 14 is fixed to the air inlet 17 through an adapter. When the material falls into the turntable 12, the blower 14 starts and dries the material by blowing air.

[0050] The crushing mechanism includes a fourth motor 27, a fifth motor 28, a sixth motor 29, a screen cover 30, a crushing gear 31, a material collection funnel 32, a rolling bearing 33, and a material conveyor belt 34. The fourth motor 27 is fixed to one side of the preparation shell 1, and the screen cover 30 is fixed to the output end of the fourth motor 27. There is a gap between the screen cover 30 and the collection funnel 4. The fifth motor 28 and the sixth motor 29 are fixed to the other side of the preparation shell 1. The crushing gear 31 is fixed to the output end of both the fifth motor 28 and the sixth motor 29. The material conveyor belt 34 and the material collection funnel 32 are arranged inside the screen cover 30. The bearing center fixing part of the rolling bearing 33 is used to connect the material collection funnel 32, the material conveyor belt 34, and the fifth motor 28. The bearing fasteners of the rolling bearing 33 are used to connect the screen cover 30 and the rolling bearing 33, ensuring that the rolling bearing 33 will not shift position during operation. The material conveyor belt 34 has upper and lower holes at its upper and lower ends, respectively. The upper hole connects to the material collection funnel 32, and the lower hole corresponds to the position of the crushing gear 31. When the power is turned on, the fourth motor 27 drives the screen cover 30 to rotate, and the fifth motor 28 and the sixth motor 29 drive the crushing gear 31 to rotate. The dried coarse material is transported to the inside of the screen cover 30 via the material conveyor belt 34, and the material falls from the lower hole of the material conveyor belt 34 onto the crushing gear 31. The material that has undergone initial crushing is then screened by the continuously rotating screen cover 30. The screen cover 30 has bent purlins inside, which transport insufficiently crushed material to the material collection funnel 32 above the material conveyor belt 34 for secondary crushing until the material meets the preparation requirements.

[0051] The ball milling mechanism includes a mounting frame 35, a base 36, a seventh motor 37, a cross-shaped planetary carrier 38, an eighth motor 39, a ring-shaped gear track 40, a driving sun gear 41, planetary gears 42, a ball milling container 43, and a circular base 46. A ball mill outer shell is fixed to one end corner of the bottom inner side of the housing 1. The mounting frame 35 is fixed to the inner side of the ball mill outer shell. The seventh motor 37 is fixed to the inner side of the mounting frame 35. The output end of the seventh motor 37 is fixed to the base 36. The circular base 46 is fixed to the top of the base 36. The eighth motor 39 is fixed to the bottom of the circular base 46. The output end of the instrument is fixed to a cross-shaped planetary carrier 38 and a driving sun gear 41 through a circular base 46. Multiple planetary gears 42 are evenly meshed on the outer side of the driving sun gear 41. Each planetary gear 42 is rotatably connected to the cross-shaped planetary carrier 38 via bearings. A ring-shaped gear track 40 is meshed on the outer side of each planetary gear 42 and fixed to the circular base 46. A grinding container 43 is fixed to the top of each planetary gear 42. First, the grinding container 43 is opened to receive the material from the previous step. After the grinding container 43 is fully filled, it is closed. Then, the eighth motor 39 starts working, driving the driving sun gear 41, which in turn drives the planetary gears 42 to simultaneously revolve and rotate, causing the grinding container 43 to rotate synchronously. After the material inside the grinding container 43 is fully ground, the seventh motor 37 starts working, driving the entire instrument to rotate up and down. After rotation, the outer cover 44 is opened, and the inner cover 45 is tightly closed, allowing the internal material to fall through the screen into the lower pan. After the material has been poured out, it is flipped back to its initial state to continue the next operation.

[0052] Example 2

[0053] Further optimizations to Example 1, specifically, such as... Figure 7-10As shown, the drying mechanism also includes a load-bearing structure 9, a rotary blade 10, a thrust ball bearing 13, a second motor 19, a third motor 20, a cylindrical shaft 23, a first gear 24, a second gear 25, and a bottom cover plate 26. The load-bearing structure 9 is fixed to the bottom inside the outer casing 7. The third motor 20 is fixed to the bottom of the load-bearing structure 9. A vertical shaft is fixed to the output end of the third motor 20. The vertical shaft is rotatably connected to the load-bearing structure 9 and the turntable 12 via the thrust ball bearing 13. The second motor 19 is fixed to the top of the load-bearing structure 9. The first gear 24 is fixed to the output end of the second motor 19. A second gear 25 is meshed with the outer side of a gear 24. A cylindrical shaft 23 is fixed to the inner side of the second gear 25. The inner side of the cylindrical shaft 23 is rotatably connected to a vertical shaft. A rotating blade 10 is fixed to the top of the vertical shaft. When the rotating blade 10 is driven to rotate, the material is evenly spread. The top of the cylindrical shaft 23 is fixed to the turntable 12. A bottom cover plate 26 is provided at the bottom of the load-bearing structure 9. When the second motor 19 is started, the output end of the second motor 19 drives the first gear 24 to mesh with the second gear 25 to rotate, which in turn causes the second gear 25 to drive the cylindrical shaft 23 to rotate, ultimately realizing the rotation of the turntable 12.

[0054] Example 3

[0055] Further optimizations to Example 1, specifically, such as... Figure 7-9 As shown, a lifting mechanism is installed on the top of the turntable 12. The lifting mechanism includes an inner cover 11, a first motor 15, a dust cover 21, and a rack 22. Two first motors 15 are fixed on the top of the outer cover 8. The output ends of the first motors 15 are connected to the rack 22 through drive gears. The outer sides of the rack 22 are slidably connected to the dust cover 21. The tops of the dust covers 21 are fixed to the outer cover 8. An inner cover 11 is fixed to the bottom of the two dust covers 21. The inner cover 11 is in close contact with the turntable 12. The inner side of the inner cover 11 has a protruding mounting structure for placing the built-in temperature and humidity sensors. When working, firstly, raw materials such as volcanic ash fall into the turntable 12 from the raw material inlet 16. At this time, the inner cover 11 is still in the unlifted state. Once the temperature and humidity reach the predetermined drying standard, the first motor 15 starts working, causing the rack 22 to rise, thereby lifting the inner cover 11. After the material is thrown out, the output end of the first motor 15 is controlled to rotate, and the inner cover 11 begins to descend and stops moving after contacting the turntable 12.

[0056] Example 4

[0057] Further optimizations to Example 1, specifically, such as... Figure 21 and 22As shown, the ball mill mechanism also includes an outer cover 44 and an inner cover 45. Small motors are fixed to both sides of the top of the ball mill container 43. The output ends of the small motors are respectively fixed to the outer cover 44 and the inner cover 45. A screen is installed on the inner cover 45, with a mesh size that only allows material particles to pass through. Driven by the small motors, it can be controlled to automatically open and close. After grinding is complete and the entire cross-shaped planetary carrier 38 is flipped, only the outer cover 44 can be opened while the inner cover 45 is tightly closed. In this way, the material inside will fall through the screen due to gravity, but the steel balls used for grinding inside the ball mill container 43 cannot pass through the screen.

[0058] In summary:

[0059] This invention addresses the following technical problem: Currently, most simulated lunar regolith preparation devices employ a step-by-step process, first drying raw materials such as volcanic ash using drying equipment, then crushing the dried material in a crusher, and finally grinding the material to obtain the final simulated lunar regolith. These steps are performed by different devices, requiring manual transfer between them. The entire process has a low degree of automation, making it difficult to guarantee preparation efficiency. Furthermore, the simulated lunar regolith may be contaminated during transfer. By adopting the technical solutions of the above embodiments, and through the aforementioned setup, this application can certainly solve the above-mentioned technical problems, and simultaneously achieve the following technical effects:

[0060] 1. The entire process is fully automated and integrated. By connecting three modules—drying, crushing, and ball milling—in series, it achieves a "production line" processing from raw materials such as volcanic ash to finished lunar soil, eliminating manual handling and significantly improving production efficiency. The optimized equipment size results in a compact layout, improving space utilization. The drying pretreatment reduces crushing energy consumption, and a 30-mesh initial sieve is achieved through a screen cover.

[0061] 2. A dust-free intelligent environment is achieved through a transparent gel-based preparation shell 1, which ensures operational safety and facilitates real-time monitoring of the operating status of each processing unit. This invention realizes intelligent control of all elements of "raw materials-process-environment" through electromechanical coupling design, providing high-fidelity simulated lunar soil for lunar construction research, and has significant engineering application value.
