Description

Technical Field

[0001] The present invention relates to the technical field of simulated lunar soil preparation, and particularly to an automatic simulated lunar soil preparation device. Background Technique

[0002] At present, China's lunar exploration project has achieved remarkable results, and the research on the moon is also being vigorously promoted. Given the scarcity of real lunar soil resources, it is particularly important to prepare simulated lunar soil. The original intention of this measure is that in order to carry out lunar construction research, these simulated lunar soils are urgently needed as research bases. At the same time, these simulated lunar soils can also build a simulated lunar environment on the earth, providing valuable conditions for the research and development of lunar robots. Preparing simulated lunar soil on the earth can provide a large number of samples for scientific research personnel to use in research. Under the conditions of simulating the real lunar environment, scientific research personnel can explore the physical and chemical properties of lunar soil and seek its change laws under different conditions, so as to deeply understand the evolutionary history and geological characteristics of the moon.

[0003] However, at present, most simulated lunar soil preparation devices adopt a step-by-step method, that is, first use a drying device to dry raw materials such as volcanic ash, then put the dried materials into a crusher for crushing, and finally grind the materials to obtain the final simulated lunar soil. The above steps are completed by different devices, and manual transfer is required between different devices. This not only results in a low degree of automation in the whole process and difficult to guarantee the preparation efficiency, but also may cause the simulated lunar soil to be contaminated during the transfer process.

[0052] Embodiment 2

[0053] Further optimize Embodiment 1. Specifically, as Figures 7-10As shown in the figure, the drying mechanism further includes a load-bearing structure 9, a rotary knife 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 housing 7. The third motor 20 is fixed to the bottom of the load-bearing structure 9. The output end of the third motor 20 is fixed with a vertical shaft, and the vertical shaft is rotatably connected to the load-bearing structure 9 and the turntable 12 through the thrust ball bearing 13. The second motor 19 is fixed to the top of the load-bearing structure 9. The output end of the second motor 19 is fixed with the first gear 24.

The bottom of the load-bearing structure 9 is provided with the bottom cover plate 26. 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 and rotate, thereby causing the second gear 25 to drive the cylindrical shaft 23 to rotate, and finally realizing the rotation of the turntable 12.

[0054] Embodiment 3

[0055] Further optimize Embodiment 1. Specifically, as Figures 7-9 shown in the figure, a lifting mechanism is assembled on the top of the turntable 12. The lifting mechanism includes an inner cover 11, a first motor 15, a dust-proof cover 21, and a rack 22. Two first motors 15 are fixed to the top of the housing cover 8. The output ends of the first motors 15 are both meshed and connected with the rack 22 through drive gears. The outer sides of the racks 22 are both slidably connected with the dust-proof covers 21. The tops of the dust-proof covers 21 are both fixed to the housing cover 8. The bottoms of the two dust-proof covers 21 are fixed with an inner cover 11. The inner cover 11 is in close contact with the turntable 12. The inner side of the inner cover 11 is provided with a protruding mounting structure for placing the built-in temperature and humidity sensors. When working, first, raw materials such as volcanic ash fall onto the turntable 12 from the raw material inlet 16. At this time, the inner cover 11 is still in the non-lifted state. When the temperature and humidity reach the predetermined drying standard, the first motor 15 starts to work, causing the rack 22 to rise, thereby driving the inner cover 11 to rise. After the materials are thrown out, control the rotation direction of the output end of the first motor 15, and the inner cover 11 starts to descend and stops moving after contacting the turntable 12.

[0056] Embodiment 4

[0057] Further optimize Embodiment 1. Specifically, as Figure 21 and 22As shown in the figure, the ball milling mechanism further includes an outer cover 44 and an inner cover 45. Small motors are fixed on both sides of the top of the ball milling container 43. The output ends of the small motors are respectively fixed with the outer cover 44 and the inner cover 45. A screen is arranged on the inner cover 45, and the aperture of the screen only allows material particles to pass through. By driving the small motors, the automatic opening and closing of the covers can be controlled. After the entire cruciform planet carrier 38 is flipped when the grinding is completed, only the outer cover 44 can be opened while the inner cover 45 is tightly closed. In this way, the internal material will fall through the screen due to gravity, but the steel balls used for grinding inside the ball milling container 43 cannot pass through the screen.

[0058] As can be seen from the above:

[0059] For the technical problem of the present invention: At present, most of the simulated lunar soil preparation devices are carried out step by step, that is, first use a drying device to dry raw materials such as volcanic ash, then put the dried materials into a crusher for crushing, and grind the materials to obtain the final simulated lunar soil. The above steps are completed by different devices, and manual transfer is required between different devices. The automation degree of the whole process is relatively low, the preparation efficiency is difficult to guarantee, and the simulated lunar soil may be contaminated during the transfer process; by adopting the technical solutions of the above embodiments, through the above settings, this application will surely solve the above technical problems, and at the same time, achieve the following technical effects:

[0060] 1. Full-process automatic integration, through the transmission to connect in series the three modules of drying - crushing - ball milling, realizing the "assembly line type" processing from raw materials such as volcanic ash to finished lunar soil, eliminating the manual transfer link, and significantly improving the preparation efficiency; the equipment size is optimized to form a compact layout, improving the space utilization rate. The pre-treatment of drying reduces the crushing energy consumption and realizes the primary screening of 30 meshes of the mesh screen outer cover.

[0061] 2. Dust-free intelligent environment, through the preparation housing 1 made of transparent gel, which not only ensures operation safety but also facilitates real-time monitoring of the operating states of each processing unit. The present invention realizes the intelligent control of all elements of "raw materials - process - environment" through the electromechanical coupling design, providing high-fidelity simulated lunar soil for lunar construction research, and having significant engineering application value.
