Description

Technical Field

[0001] This invention belongs to the field of lunar soil exploration technology, and more specifically, it relates to a lunar soil core sampling transmission mechanism and a lunar soil core sampling device modeled after the Luoyang shovel. Background Technology

[0002] The Moon, being the closest extraterrestrial body to Earth, allows for the analysis of lunar regolith or rock samples. This analysis provides information on the lunar regolith's bedding structure and mineral composition, laying the groundwork for lunar resource extraction. Therefore, obtaining lunar regolith profiles with pristine bedding information is a crucial aspect of manned lunar missions. Currently, the optimal sampling method for preserving sample bedding is percussion sampling. Based on terrestrial percussion sampling devices, the Luoyang shovel method has proven to be the most convenient and effective, widely used in archaeology, railways, and mining. Applying the Luoyang shovel sampling device to lunar core sampling could significantly increase the depth of lunar regolith sampling by astronauts. However, the simple Luoyang shovel core sampling device is only suitable for sampling relatively loose lunar regolith layers. It cannot penetrate deep, denser lunar regolith and cannot overcome the formation of force chains within the core tube to improve the core recovery rate, presenting several challenges. Therefore, in order to maximize the integrity of the sample layer while improving sampling depth and efficiency during manned lunar missions, further improvements need to be made to the Luoyang shovel-type coring device to suit the lunar environment, so as to facilitate astronauts to conduct efficient and deep coring of lunar soil on the lunar surface. Summary of the Invention

[0003] The purpose of this invention is to provide a lunar soil coring transmission mechanism and a Luoyang shovel-type lunar soil coring device to solve the technical problems in the prior art, such as the inability to penetrate deep, dense lunar soil, the inability to overcome the formation of force chains in the coring tube, and the low coring rate.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a lunar soil coring transmission mechanism is provided for driving a coring tube. The lunar soil coring transmission mechanism includes a driving component that outputs rotational motion, a transmission shaft connected to the driving component, a rotating vibrating block connected to the transmission shaft, an impact component connected to the transmission shaft and used to impact the rotating vibrating block, and a vibration component that generates vibration on the rotating vibrating block under the impact of the impact component. The rotating vibrating block is used to connect with the coring tube.

[0005] Optionally, the impact assembly includes a first vibrating block fixedly connected to the drive shaft, a second vibrating block placed on the first vibrating block, an impact hammer fixedly connected to the second vibrating block, and a first elastic element. The adjacent surfaces of the first vibrating block and the second vibrating block are both undulating surfaces. The impact hammer is used to impact the rotating vibrating block. One end of the first elastic element is fixedly disposed, and the other end of the first elastic element abuts against the side of the second vibrating block opposite to the first vibrating block.

[0006] Optionally, the second vibration block, the first vibration block, the impact hammer, and the rotating vibration block are coaxially arranged, and the first elastic element, the second vibration block, the impact hammer, and the rotating vibration block are arranged sequentially along the axial direction of the transmission shaft.

[0007] Optionally, the impact hammer includes a cylindrical portion and an impact portion. A ring-shaped boss is formed radially outwardly protruding around one end of the second vibrating block. The end of the second vibrating block away from the ring-shaped boss and the first vibrating block are both located inside the cylindrical portion. One end of the cylindrical portion is fixedly connected to the ring-shaped boss, and the other end of the cylindrical portion is connected to the impact portion. The impact portion is directly opposite the rotating vibrating block.

[0008] Optionally, the lunar soil coring transmission mechanism further includes a housing assembly, with at least the impact hammer disposed within the housing assembly. The outer wall of the impact hammer is provided with a first circumferential positioning part, and the inner wall of the housing assembly is provided with a second circumferential positioning part. The first circumferential positioning part and the second circumferential positioning part cooperate to prevent the impact hammer from rotating circumferentially.

[0009] Optionally, the vibration assembly includes a plurality of vibrating particles disposed inside the rotating vibrating block;

[0010] Alternatively, the lunar soil coring transmission mechanism may further include a housing assembly, with at least the rotating vibrating block disposed within the housing assembly, and the vibration assembly comprising a plurality of vibrating particles disposed between the housing assembly and the rotating vibrating block.

[0011] Optionally, the vibrating particles are disposed between the housing assembly and the rotating vibrating block, and a particle receiving groove is formed between the inner peripheral wall of the housing assembly and the outer peripheral wall of the rotating vibrating block, wherein the width of the particle receiving groove is greater than the diameter of the vibrating particles.

[0012] The present invention also provides a lunar soil coring device similar to the Luoyang shovel type, including the above-mentioned lunar soil coring transmission mechanism, and further including a coring tube and a power connection structure. The power connection structure is used to electrically connect with the driving component, and the coring tube is connected to the rotating vibration block.

[0013] Optionally, the power connection structure includes a power communication external connector and a connecting rod connected to the power communication external connector. The end of the connecting rod away from the power communication external connector has a pressing head. A second elastic element is provided between the pressing head and the lunar soil coring transmission mechanism. The connecting rod and the pressing head, as well as the pressing head and the driving component, are all electrically connected via contacts; or...

[0014] The power connection structure includes an external power cord and a connecting rod. The connecting rod is hollow, and one end of the connecting rod is fixedly connected to the lunar soil coring transmission mechanism. The external power cord passes through the connecting rod and is electrically connected to the driving component.

[0015] Optionally, the coring tube includes a tube body and a partition disposed inside the tube body. The two sides of the partition are a chip-containing cavity and a core-storing cavity for storing lunar soil, respectively. The bottom of the chip-containing cavity is provided with a connector for connecting to the rotating vibrating block, and the side wall of the chip-containing cavity is provided with a chip-flowing hole penetrating the coring tube.

[0016] The beneficial effects of the lunar soil coring transmission mechanism and the imitation Luoyang shovel-type lunar soil coring device provided by this invention are as follows: Compared with the prior art, the lunar soil coring transmission mechanism of this invention includes a driving component, a transmission shaft, a rotating vibrating block, an impact component, and a vibration component. The rotating vibrating block is used to connect to the coring tube. The transmission shaft can drive the rotating vibrating block to rotate, and at the same time, the impact component can continuously impact the rotating vibrating block. While impacting the rotating vibrating block, the impact component also causes the vibration component to vibrate the rotating vibrating block. Thus, when the transmission shaft rotates, the rotating vibrating block not only rotates but is also affected by the impact of the impact component and the vibration of the vibration component, disrupting the force chain formation in the coring tube and significantly improving the coring rate and sampling depth.

[0034] The lunar soil coring transmission mechanism provided in the embodiments of the present invention will now be described.

[0035] Please refer to the following: Figures 1 to 3The lunar soil coring transmission mechanism 1 includes a driving component 11, a transmission shaft 12, a rotating vibrating block 13, an impact assembly 14, and a vibration assembly 15. The driving component 11 is capable of outputting rotational motion and can be selected as a motor or other mechanism capable of outputting rotational motion. The transmission shaft 12 is connected to the driving component 11 and is driven to rotate by the driving component 11. The rotating vibrating block 13 is connected to the transmission shaft 12, and rotates accordingly when the transmission shaft 12 rotates. The impact assembly 14 is connected to the transmission shaft 12, and when the transmission shaft 12 rotates, the impact assembly 14 generates an impact motion, impacting the rotating vibrating block 13. Simultaneously, while the impact assembly 14 impacts the rotating vibrating block 13, the vibration assembly 15 vibrates the rotating vibrating block 13. As described above, when the driving component 11 is working, the rotating vibrating block 13 rotates, the impact assembly 14 impacts the rotating vibrating block 13, and the vibration assembly 15 vibrates the rotating vibrating block 13. The rotating vibrating block 13 is used to connect with the core sampling tube 2, which is used to insert into the lunar soil for lunar soil sampling.

[0036] Specifically, when the lunar soil coring transmission mechanism 1 and the coring tube 2 are engaged, the astronaut presses down on the lunar soil coring transmission mechanism 1 and the coring tube 2, and the coring tube 2 receives a downward penetration force. At the same time, the drive component 11 works, and the impact component 14 and the vibration component 15 provide vibration impact force to the coring tube 2. The coring tube 2 generates a rotational cutting force as the rotating vibrating block 13 rotates. Under the coupled action of the penetration force, vibration impact force and rotational cutting force, the formation of force chain in the coring tube 2 can be disrupted, thereby greatly improving the sampling efficiency and sampling depth of the coring device.

[0037] The lunar soil coring transmission mechanism 1 in the above embodiment includes a drive component 11, a drive shaft 12, a rotating vibrating block 13, an impact component 14, and a vibration component 15. The rotating vibrating block 13 is connected to the coring tube 2. The drive shaft 12 can drive the rotating vibrating block 13 to rotate, while the impact component 14 continuously impacts the rotating vibrating block 13. Simultaneously, the impact component 14 impacts the rotating vibrating block 13, causing the vibration component 15 to vibrate it. Thus, when the drive shaft 12 rotates, the rotating vibrating block 13 not only rotates but is also affected by the impact of the impact component 14 and the vibration of the vibration component 15, disrupting the force chain formation in the coring tube 2 and significantly improving the coring rate and sampling depth.

[0038] In one embodiment of the present invention, please refer to Figures 2 to 5The impact assembly 14 includes a first vibrating block 141, a second vibrating block 142, an impact hammer 143, and a first elastic element 144. The first vibrating block 141 is fixedly connected to the drive shaft 12 and can rotate synchronously with the drive shaft 12. The second vibrating block 142 is placed on the first vibrating block 141 and is fixedly connected to the impact hammer 143. One end of the first elastic element 144 is fixedly disposed, and the other end of the first elastic element 144 abuts against the side of the second vibrating block 142 facing away from the first vibrating block 141. The adjacent surfaces of the first vibrating block 141 and the second vibrating block 142 are both uneven surfaces. Furthermore, the second vibrating block 142 is placed on the first vibrating block 141, and under the elastic force provided by the first elastic element 144, there is a certain pressure between the first vibrating block 141 and the second vibrating block 142. When the first vibrating block 141 rotates with the drive shaft 12, the concave and convex surfaces of the first vibrating block 141 and the second vibrating block 142 generate relative motion, thereby causing the second vibrating block 142 to continuously generate axial motion (along the axial direction of the drive shaft 12). The impact hammer 143 continuously impacts the rotating vibrating block 13, causing the core tube 2 to continuously move up and down, which can effectively disrupt the formation of force chains in the core tube 2. The concave and convex surfaces of the first vibrating block 141 and the second vibrating block 142 are both perpendicular to the axial direction of the drive shaft 12, so that the second vibrating block 142 can generate reciprocating axial motion.

[0039] Optionally, the adjacent surfaces of the first vibrating block 141 and the second vibrating block 142 are both sawtooth surfaces, that is, the adjacent surfaces of the first vibrating block 141 and the second vibrating block 142 are sawtooth-shaped. The adjacent surfaces of the first vibrating block 141 and the second vibrating block 142 are also wavy. It should be noted that the adjacent surfaces of the first vibrating block 141 and the second vibrating block 142 can also be surfaces of other shapes, as long as they can enable the second vibrating block 142 to move axially relative to the first vibrating block 141.

[0040] In one embodiment of the present invention, please refer to Figure 2 and Figure 3 The second vibrating block 142, the first vibrating block 141, the impact hammer 143 and the rotating vibrating block 13 are coaxially arranged, which facilitates the impact hammer 143 to reciprocate in the axial direction to impact the rotating vibrating block 13. It also allows the internal structure of the lunar soil core extraction transmission mechanism 1 to be distributed along the axial direction of the transmission shaft 12, thereby minimizing the diameter of the lunar soil core extraction transmission mechanism 1.

[0041] The first elastic element 144, the second vibrating block 142, the impact hammer 143, and the rotating vibrating block 13 are arranged sequentially along the axial direction of the transmission shaft 12. The first elastic element 144 exerts a certain pressure on the second vibrating block 142, ensuring that the second vibrating block 142 and the first vibrating block 141 are always in contact. When the lunar soil coring transmission mechanism 1 is in normal use, the first elastic element 144, the second vibrating block 142, the impact hammer 143, the rotating vibrating block 13, and the coring tube 2 are arranged sequentially from top to bottom.

[0042] Optionally, the driving component 11 and the rotating vibrating block 13 can be disposed at both ends of the transmission shaft 12, so that the internal structure of the lunar soil coring transmission mechanism 1 is distributed along the axial direction of the transmission shaft 12, thereby minimizing the diameter of the lunar soil coring transmission mechanism 1. In order to accommodate the rotational speed of the transmission shaft 12, a transmission assembly can be provided between the driving component 11 and the transmission shaft 12.

[0043] In one embodiment of the present invention, please refer to Figure 4 The impact hammer 143 includes a cylindrical portion 1431 and an impact portion 1432. The cylindrical portion 1431 is fixedly connected to the second vibrating block 142, and the impact portion 1432 is used to impact the rotating vibrating block 13. An annular boss 1421 is formed radially outwardly protruding from one end of the second vibrating block 142. The other end of the second vibrating block 142 extends into the cylindrical portion 1431, and the annular boss 1421 is fixedly connected to one end of the cylindrical portion 1431. The other end of the cylindrical portion 1431 is connected to the impact portion 1432. The first vibrating block 141 is also located within the cylindrical portion 1431. This configuration of the impact hammer 143 achieves a fixed connection with the second vibrating block 142 while utilizing axial space to the maximum extent possible, and also enables it to impact the rotating vibrating block 13.

[0044] In one embodiment of the present invention, please refer to Figure 2 and Figure 3 The lunar soil coring transmission mechanism 1 also includes a housing assembly 16. A drive component 11, a transmission shaft 12, a rotating vibrating block 13, an impact component 14, and a vibration component 15 are evenly arranged inside the housing assembly 16. A bearing 17 is provided between the transmission shaft 12 and the housing assembly 16, which makes the rotation of the transmission shaft 12 more stable and reduces the radial runout of the transmission shaft 12. A stop boss is provided on the inner wall of the housing assembly 16. One end of the first elastic member 144 abuts against the stop boss, and the other end of the first elastic member 144 abuts against the second vibrating block 142. The bearing 17 can be disposed between the stop boss and the transmission shaft 12.

[0045] In one embodiment of the present invention, please refer to Figure 5The lunar soil coring transmission mechanism 1 also includes a housing assembly 16, with at least an impact hammer 143 disposed inside the housing assembly 16. The outer wall of the impact hammer 143 is provided with a first circumferential positioning part 1433, and the inner wall of the housing assembly 16 is provided with a second circumferential positioning part 161. The first circumferential positioning part 1433 and the second circumferential positioning part 161 cooperate with each other to prevent the circumferential rotation of the impact hammer 143 and the second vibration block 142.

[0046] Optionally, the first circumferential positioning portion 1433 is a strip-shaped protrusion, and the second circumferential positioning portion 161 is a strip-shaped groove. Both the strip-shaped protrusion and the strip-shaped groove are arranged along the axial direction of the drive shaft 12, thus fixing the circumferential position of the impact hammer 143 and preventing it from rotating relative to the housing assembly 16. In other embodiments, the first circumferential positioning portion 1433 is a strip-shaped groove, and the second circumferential positioning portion 161 is a strip-shaped protrusion. The specific shapes of the first circumferential positioning portion 1433 and the second circumferential positioning portion 161 are not limited here, as long as they can prevent the impact hammer 143 from rotating circumferentially.

[0047] Optionally, there are multiple first circumferential positioning parts 1433 and multiple second circumferential positioning parts 161, and the number is the same. The multiple first circumferential positioning parts 1433 are arranged at intervals along the outer circumference of the impact hammer 143, and the multiple second circumferential positioning parts 161 are arranged at intervals along the inner circumference of the housing assembly 16.

[0048] In one embodiment of the present invention, the vibration assembly 15 includes a plurality of vibration particles 151 disposed inside the rotating vibration block 13. When the impact assembly 14 impacts the rotating vibration block 13, the vibration particles 151 inside the rotating vibration block 13 will move continuously under the impact, generating vibration on the rotating vibration block 13, which can further disrupt the formation of the force chain within the core tube 2.

[0049] In one embodiment of the present invention, please refer to Figure 4 and Figure 5 At least the rotating vibrating block 13 is disposed within the housing assembly 16, and the vibration assembly 15 includes a plurality of vibrating particles 151 disposed between the housing assembly 16 and the rotating vibrating block 13. When the impact assembly 14 impacts the rotating vibrating block 13, the vibrating particles 151 will be affected by the rotating vibrating block 13 and move up and down continuously, generating vibration on the rotating vibrating block 13, which can further disrupt the formation of the force chain within the core tube 2.

[0050] Optionally, a particle receiving groove 131 is formed between the inner peripheral wall of the outer casing assembly 16 and the outer peripheral wall of the rotating vibrating block 13, and the vibrating particles 151 are disposed inside the particle receiving groove 131. The particle receiving groove 131 may be annular, and multiple vibrating particles 151 are arranged sequentially along the annular shape of the particle receiving groove 131. The width of the particle receiving groove 131 is greater than the diameter of the vibrating particles 151, so that the vibrating particles 151 can jump in the width direction of the particle receiving groove 131, generating a certain vibration effect on the rotating vibrating block 13.

[0051] Optionally, the particle receiving groove 131 is provided on the outer peripheral wall of the rotating vibrating block 13; or, the particle receiving groove 131 is provided on the inner peripheral wall of the housing assembly 16; or, both the inner peripheral wall of the housing assembly 16 and the outer peripheral wall of the rotating vibrating block 13 are provided with annular grooves, and the two annular grooves are combined to form the particle receiving groove 131.

[0052] Optionally, the vibrating particles 151 can be steel balls. Steel balls have a higher density, and among vibrating particles 151 of the same volume made of various materials, steel balls have a larger mass and thus a greater impact force on the rotating vibrating block 13.

[0053] In one embodiment of the present invention, please refer to Figure 4 The outer casing assembly 16 has a through hole with a diameter larger than that of the vibrating particle 151, and the through hole communicates with the particle receiving groove 131. After the rotating vibrating block 13, the outer casing assembly 16, etc. are installed, the vibrating particles 151 are placed one by one into the particle receiving groove 131 through the through hole. A groove cap 18 is provided to cover the through hole, so that the particle receiving groove 131 is in a closed state. The through hole and groove cap 18 on the outer casing assembly 16 facilitate the installation of the vibrating particles 151 and prevent the vibrating particles 151 from falling out.

[0054] Please see Figures 6 to 10 The present invention also provides a lunar soil coking device modeled after the Luoyang shovel, which includes the lunar soil coking transmission mechanism 1 in any of the above embodiments. The device further includes a coking tube 2 and a power connection structure 3. The coking tube 2 is connected to a rotating vibrating block 13, and the power connection structure 3 is electrically connected to a driving component 11 to provide power to the lunar soil coking transmission mechanism 1.

[0055] The lunar soil coring device based on the Luoyang shovel type provided by this invention employs the aforementioned lunar soil coring transmission mechanism 1. The transmission shaft 12 can drive the rotating vibrating block 13 to rotate, while simultaneously causing the impact component 14 to continuously impact the rotating vibrating block 13. During this impact, the vibration component 15 also causes the rotating vibrating block 13 to vibrate. Thus, when the transmission shaft 12 rotates, the rotating vibrating block 13 not only rotates but is also affected by the impact of the impact component 14 and the vibration of the vibration component 15, disrupting the force chain formation in the coring tube 2 and significantly improving the coring rate.

[0056] In one embodiment of the present invention, please refer to Figure 7 The power connection structure 3 includes a power communication external connector 31 and a connecting rod 32, which are sequentially connected to the lunar soil coring transmission mechanism 1. The power communication external connector 31 is electrically connected to an external power source. The power communication external connector 31 and the connecting rod 32 can be threaded together or electrically connected via contacts. The number of connecting rods 32 can be one or more, and multiple connecting rods 32 can be connected together to increase the overall length of the connecting rods 32, thereby achieving deep coring. The end of the connecting rod 32 away from the power communication external connector 31 has a pressing head 33, and a second elastic element 36 is provided between the pressing head 33 and the lunar soil coring transmission mechanism 1. When the coring personnel press the connecting rod 32, the connecting rod 32 drives the pressing head 33 to press down, the second elastic element 36 contracts, and the contacts on the connecting rod 32 and the contacts on the driving element 11 come into contact, energizing the driving element 11, causing the rotating vibrating block 13 to vibrate, and the coring tube 2 begins coring work; when the coring personnel stop pressing or lift the entire coring device upward, the second elastic element 36 automatically rebounds, the contacts on the connecting rod 32 and the contacts on the driving element 11 separate, the driving element 11 is de-energized, and the coring tube 2 stops operating, which can prevent the lunar soil inside the coring tube 2 from falling out.

[0057] Optionally, the connecting rod 32 and the pressing head 33 are threaded together, and are also electrically connected via contacts. The end of the connecting rod 32 away from the power communication connector 31 has a first positive contact 321 and a first negative contact 322. The end of the pressing head 33 used to connect to the connecting rod 32 has a second positive contact 331 and a second negative contact 332. After the connecting rod 32 and the pressing head 33 are connected, the first positive contact 321 and the second positive contact 331 are in contact and conductive, and the first negative contact 322 and the second negative contact 332 are in contact and conductive. The pressing head 33 also has a third positive contact 333 and a third negative contact 334, and the driving member 11 has a fourth positive contact 111 and a fourth negative contact 112. When the pressing head 33 is pressed, the third positive contact 333 and the fourth positive contact 111 make contact and conduct, and the third negative contact 334 and the fourth negative contact 112 conduct, so that the pressing head 33 can conduct with the driving member 11.

[0058] In one embodiment of the present invention, please refer to Figure 8 The power connection structure 3 includes an external power cord 34 and a connecting rod 35. The connecting rod 35 is hollow. One end of the connecting rod 35 is fixedly connected to the lunar soil core extraction transmission mechanism 1. The external power cord 34 passes through the interior of the connecting rod 35 to the driving component 11 and is electrically connected to the driving component 11.

[0059] In one embodiment of the present invention, please refer to Figure 9 The core sampling tube 2 includes a tube body 21 and a partition 22. The partition 22 is disposed inside the tube body 21, dividing the internal space of the tube body 21 into a debris chamber 24 and a core storage chamber 25. The core storage chamber 25 is used to store the extracted lunar soil sample, and the debris chamber 24 is used to collect lunar soil debris generated during the sampling process. A connector 23 is provided at the bottom of the debris chamber 24, which is used to connect with the rotating vibrating block 13. The connector 23 may be threaded to allow the connector 23 and the rotating vibrating block 13 to be threadedly connected. The side wall of the debris chamber 24 has a debris discharge hole 26 that penetrates the core sampling tube 2, allowing the lunar soil in the debris chamber 24 to be discharged. The shape and number of debris discharge holes 26 are not limited here.

[0060] Optionally, the end of the core tube 2 away from the rotating vibrating block 13 has cutting teeth 27, so that the rotating vibrating block 13 can quickly cut the lunar soil when it rotates, allowing the lunar soil to enter the core tube 2.

[0061] In one embodiment of the present invention, please refer to Figure 6 and Figure 10The outer diameters of the power connection structure 3 and the lunar soil coring transmission mechanism 1 are both smaller than the outer diameter of the coring tube 2. This ensures that only the coring tube 2 is in direct contact with the lunar soil during coring, reducing frictional losses. The lunar soil coring transmission mechanism 1 is installed downhole and is tightly connected to the coring tube 2, effectively reducing force loss during transmission.

[0062] It should be noted that the lunar soil core extraction transmission mechanism 1 and the imitation Luoyang shovel-type lunar soil core extraction device in this invention can be used not only for lunar soil core extraction, but also for soil core extraction from other planets.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
