Description

Technical Field

[0001] The present invention relates to the field of solid sample and volatile matter transportation and extraction technology, and in particular to a low-spillage direct-access bulk lunar soil sample receiving device. Background Art

[0002] With advances in aerospace technology, lunar soil research and exploration are becoming increasingly important for the development and utilization of lunar resources. Specifically, lunar soil contains volatiles such as H₂, CO₂, N₂, CH₄, NH₃, H₂O, and other rare gases. These volatiles can reveal insights into planetary formation and evolution and are crucial resources for future lunar bases, making their analysis and research crucial. To improve the accuracy of lunar soil volatile analysis and prevent loss or alteration during sample return to Earth, in situ lunar soil analysis is essential. After sampling, in situ lunar soil volatile analysis requires transporting the lunar soil collector to a heating furnace for heating. However, the collectors are single-use, non-reusable, and are discarded after heating. Consequently, once all collectors are used up, further lunar soil analysis and testing is unavailable, limiting the number of experiments and hindering extensive experimental analysis of lunar soil. Summary of the Invention

[0003] Based on this, it is necessary to provide a low-spillage direct-access bulk lunar soil sample receiving device to address the problem that when conducting in-situ lunar soil research on the moon, after the collector is used up, the lunar soil cannot be further analyzed and tested, which makes the number of the entire experiment small and it is difficult to conduct a large number of experimental analysis and research on the lunar soil.

[0005] frame;

[0006] A first feeding assembly includes a feeding funnel and a feeding hose; the feeding funnel is fixedly connected to the frame and is configured with a first feeding cavity, and the feeding hose is connected to the small-diameter end of the feeding funnel;

[0007] a heating turntable rotatably connected to the frame and disposed opposite to the feeding funnel, and disposed on a side of the feeding hose facing away from the feeding funnel, the heating turntable comprising a first heating table having a first heating chamber with an opening;

[0008] A sampling shovel is connected to the frame and is used to collect and carry lunar soil. The sampling shovel can move closer to or farther away from the feeding funnel so that the lunar soil can slide into the first feeding cavity through the large-diameter end of the feeding funnel; the lunar soil in the first feeding cavity can slide into the feeding hose and into the first heating cavity through the small-diameter end of the feeding funnel under the action of gravity.

[0009] In one embodiment, the sampling shovel is further capable of rotating relative to the frame;

[0010] When the sampling shovel approaches the feeding funnel and moves to the first preset position, the sampling shovel rotates relative to the frame so that the lunar soil can separate from the sampling shovel and slide into the first feeding chamber.

[0011] In one embodiment, a swing arm is protruded from one side of the first heating chamber toward the opening;

[0012] When the sampling shovel approaches the feeding funnel and moves to a second preset position, the heating turntable can perform a rotational motion relative to the frame, so that the swing arm abuts against or separates from the feeding hose.

[0013] In one embodiment, the feeding hose is formed by a plurality of overlapping soft joints;

[0014] When the heating turntable rotates relative to the frame, the swing arm can abut against or separate from at least one of the soft connecting pieces.

[0015] In one embodiment, the low-spillage direct-access bulk lunar soil sample receiving device further includes a controller electrically connected to the heating turntable and the sampling shovel;

[0016] When the sampling shovel approaches and moves to a first preset position relative to the feeding funnel, the sampling shovel can send a first electrical signal to the controller, so that the controller controls the sampling shovel to rotate relative to the frame;

[0017] When the sampling shovel approaches and moves to a second preset position relative to the feeding funnel, the sampling shovel can send a second electrical signal to the controller, so that the controller controls the heating turntable to perform a rotational motion relative to the frame.

[0018] In one embodiment, the low-spillage direct-access bulk lunar soil sample receiving device further includes a first drive assembly, the first drive assembly being connected to the heating turntable and configured to drive the heating turntable to rotate around its own rotation axis;

[0019] The low-spillage direct-access bulk lunar soil sample receiving device also includes a second drive assembly, which is connected to the heating turntable; when the lunar soil in the sampling shovel slides into the first heating chamber through the feeding funnel, the sampling shovel can send a third electrical signal to the controller, so that the controller controls the second drive assembly to drive the first heating table to rotate and rise to a third preset position.

[0020] In one embodiment, the low-spillage direct-reach bulk lunar soil sample receiving device further comprises:

[0021] A second feeding assembly, the second feeding assembly comprising a feeding seat connected to the frame, the feeding seat being configured with a second feeding cavity;

[0022] a sample delivery tube, the sample delivery tube being electrically connected to the controller and having a sample delivery cavity. The sample delivery cavity is provided with a collector for carrying lunar soil; the sample delivery tube is capable of moving toward or away from the feeding seat, and one end of the sample delivery tube is capable of at least partially extending into the second feeding cavity;

[0023] The heating turntable further includes a second heating stage, wherein the second heating stage and the first heating stage are arranged at intervals along the circumference of the heating turntable;

[0024] When the sample tube approaches the feeding seat and moves to the fourth preset position, the sample tube can perform a sample discharging operation to separate the collector from the sample tube, and pass through the feeding seat to cooperate with the second heating table.

[0025] In one embodiment, the low-spillage direct-access bulk lunar soil sample receiving device also includes a detection component electrically connected to the controller, and the detection component is installed on the feeding seat. When the sample tube approaches and moves to a fourth preset position relative to the feeding seat, the detection component can detect the sample tube and send a fourth electrical signal to the controller, so that the controller controls the sample tube to perform a sample discharge operation.

[0026] In one embodiment, the low-spill direct-access bulk lunar soil sample receiving device further includes at least two rebound assemblies disposed opposite to each other and connected to the frame; and the at least two rebound assemblies are respectively disposed on a side of the feeding seat away from the second feeding cavity;

[0027] The rebound component abuts against the feeding seat and can drive the feeding seat to move along the radial direction of the feeding seat.

[0028] Beneficial effects of the present invention:

[0029] When lunar soil is analyzed and studied in situ on the moon, the collected lunar soil is transported and analyzed using the low-spillage, direct-access bulk lunar soil sample receiving device provided by the present invention. After the collector used to carry the lunar soil is used, the lunar soil is collected and carried by the sampling shovel, and the sampling shovel is moved relative to the feeding funnel, so that the lunar soil in the sampling shovel slides through the large-diameter end of the feeding funnel into the first feeding cavity. Under the action of gravity, the lunar soil in the first feeding cavity flows through the small-diameter end of the feeding funnel into the feeding hose and slides into the first heating cavity of the first heating table. Through the coordinated action of the sampling shovel and the first heating table, the lunar soil can be repeatedly analyzed and tested after the collector is used, thereby increasing the number of lunar soil analysis and testing during the entire experimental process, and thus enabling a large number of experimental analysis and research on the lunar soil. At the same time, since the device is connected to a feeding hose at the small-diameter end of the feeding funnel, when the lunar soil in the first feeding chamber slides through the small-diameter end of the feeding funnel into the first heating chamber, the feeding hose can deform itself through its own elastic deformation ability, making it difficult for the lunar soil to get blocked at the small-diameter end of the feeding funnel, and the sliding process of the lunar soil is relatively smooth.

[0054] See Figure 1-Figure 4 , Figure 1 Schematic diagram showing a cover plate 400 in an open state in a low-spillage direct-access bulk lunar soil sample receiving device provided by one embodiment of the present invention; Figure 2 Shown Figure 1 The internal structure diagram of the low-spill direct-reach bulk lunar soil sample receiving device shown in FIG. Figure 3 Shown Figure 1 Schematic diagram of the first feeding assembly 900 in the low-spill direct-access bulk lunar soil sample receiving device shown; Figure 4 Shown Figure 2 A local enlarged view of point G is shown.

[0055] An embodiment of the present invention provides a low-spillage direct-access bulk lunar soil sample receiving device, which includes a frame 600, a first feeding assembly 900, a heating turntable 800, and a sampling shovel. The first feeding assembly 900 includes a feeding funnel 910 and a feeding hose 920; the feeding funnel 910 is fixedly connected to the frame 600 and is constructed with a first feeding cavity 911, and the feeding hose 920 is connected to the small-diameter end of the feeding funnel 910; the heating turntable 800 is rotatably connected to the frame 600 and is arranged opposite to the feeding funnel 910, and the heating turntable 800 is arranged on the side of the feeding hose 920 away from the feeding funnel 910. The heating turntable 800 includes a first heating table 810, a second heating table 811, and a third heating table 812. A heating table 810 is constructed with a first heating chamber 811 with an opening; a sampling shovel (not shown in the figure) is connected to the frame 600, and the sampling shovel is used to collect and carry lunar soil. The sampling shovel can move closer to or farther away from the feeding funnel 910 so that the lunar soil can slide into the first feeding chamber 911 through the large-diameter end of the feeding funnel 910; the lunar soil in the first feeding chamber 911 can slide into the feeding hose 920 through the small-diameter end of the feeding funnel 910 under the action of gravity, and slide into the first heating chamber 811.

[0056] When lunar soil is analyzed and studied in situ on the moon, the collected lunar soil is transported and analyzed using the low-spillage, direct-access bulk lunar soil sample receiving device provided by the present invention. After the lunar soil collector 720 is used, the lunar soil is collected and carried by a sampling shovel. The sampling shovel is moved relative to the feed funnel 910, causing the lunar soil in the sampling shovel to slide through the large-diameter end of the feed funnel 910 into the first feed cavity 911. Under the influence of gravity, the lunar soil in the first feed cavity 911 flows through the small-diameter end of the feed funnel 910 into the feed hose 920 and into the first heating cavity 811 of the first heating platform 810. The coordinated operation of the sampling shovel and the first heating platform 810 allows for repeated lunar soil analysis and testing even after the collector 720 is used. This increases the number of lunar soil analyses and testing throughout the experiment, enabling a large number of experimental analyses and studies on the lunar soil. At the same time, since the device is connected to a feeding hose 920 at the small-diameter end of the feeding funnel 910, when the lunar soil in the first feeding chamber 911 slides through the small-diameter end of the feeding funnel 910 into the first heating chamber 811, the feeding hose 920 itself can deform elastically, making it difficult for the lunar soil to get blocked at the small-diameter end of the feeding funnel 910, and the sliding process of the lunar soil is relatively smooth.

[0057] It should be noted that this low-spill direct-to-scatter lunar soil sample receiving device can also be used to analyze and detect the soil on other celestial bodies, such as Venus and Mars, without limitation. This plan only uses the lunar soil of the moon as an example for explanation.

[0058] The following is a detailed description of the structure of the low-spill direct-reach bulk lunar soil sample receiving device. Figure 5-Figure 17 .

[0059] Please refer to the figure. The first feeding component 900 of the low-spill direct-access bulk lunar soil sample receiving device provided by one embodiment of the present invention also includes a third mounting seat 930, and the feeding funnel 910 is fixedly connected to the frame 600 through the third mounting seat 930.

[0060] In one embodiment, the sampling shovel is further capable of rotating relative to the frame 600. When the sampling shovel approaches and moves to a first predetermined position relative to the feeding funnel 910, the sampling shovel rotates relative to the frame 600, allowing the lunar soil to separate from the sampling shovel and slide into the first feeding chamber 911. When the sampling shovel moves to the first predetermined position relative to the feeding funnel 910, the sampling shovel rotates relative to the frame 600, causing the lunar soil in the sampling shovel to separate from the sampling shovel and slide into the first feeding chamber 911 under the action of gravity.

[0061] See also Figure 2 and Figure 4 In a low-spill, direct-access bulk lunar soil sample receiving device provided by one embodiment of the present invention, a swing arm 812 is protruded from the first heating chamber 811 on one side of the chamber facing the opening. When the sampling shovel approaches the feeding funnel 910 and moves to the second preset position, the heating turntable 800 can rotate relative to the frame 600 to cause the swing arm 812 to abut or separate from the feeding hose 920. When the lunar soil slides from the first feeding chamber 911 into the feeding tube, the swing arm 812 abuts or separates from the feeding hose 920, thereby causing the swing arm 812 to squeeze and poke the feeding hose 920 back and forth, allowing the feeding hose 920 to undergo elastic deformation. This prevents the lunar soil from becoming clogged at the small-diameter end of the feeding funnel 910 and the feeding hose 920, and ensures a smoother sliding process.

[0062] It should be noted that the first preset position and the second preset position can be the same or different, and there is no limitation on this. The only requirement is that when the sampling shovel slides to the first preset position, the lunar soil can slide into the first feeding chamber 911, and when the sampling shovel slides to the second preset position, the lunar soil in the first feeding chamber 911 has not yet slid into the feeding hose 920, or has only partially slid into the feeding hose 920. In one specific embodiment, the first preset position is the same as the second preset position, that is, the rotation of the sampling shovel relative to the frame 600 and the rotation of the heating turntable 800 relative to the frame 600 occur simultaneously. In another specific embodiment, the first preset position is different from the second preset position, and when the sampling shovel approaches the feeding funnel 910, it first passes through the first preset position and then the second preset position.

[0063] See also Figure 3The feed hose 920 of the low-spill, direct-access bulk lunar soil sample receiving device provided in one embodiment of the present invention is constructed using a plurality of overlapping flexible tabs 921. When the heating turntable 800 rotates relative to the frame 600, the swing arm 812 can contact or separate from at least one of the flexible tabs 921. Because the feed hose 920 is constructed using overlapping flexible tabs 921, the flexible tabs 921 are more likely to elastically deform when the swing arm 812 contacts or separates from them, making it less likely for lunar soil to adhere to or clog the inner walls of the tabs 921.

[0064] In one embodiment, the low-spillage, direct-access bulk lunar soil sample receiving device further includes a controller (not shown) electrically connected to the heating turntable 800 and the sampling shovel. When the sampling shovel approaches and moves to a first preset position relative to the feeding funnel 910, the sampling shovel can send a first electrical signal to the controller, causing the controller to control the sampling shovel to rotate relative to the frame 600. When the sampling shovel approaches and moves to a second preset position relative to the feeding funnel 910, the sampling shovel can send a second electrical signal to the controller, causing the controller to control the heating turntable 800 to rotate relative to the frame 600. The controller controls the sampling shovel to rotate relative to the frame 600, allowing the lunar soil in the sampling shovel to separate from the sampling shovel. The controller also controls the heating turntable 800 to rotate relative to the frame 600, causing the swing arm 812 to abut or separate from the feeding hose 920. The entire operation process is highly intelligent and accurate.

[0065] See also Figure 2 The low-spill direct-access bulk lunar soil sample receiving device provided by one embodiment of the present invention also includes a first drive assembly 1010. The first drive assembly 1010 is connected to the heating turntable 800, and the first drive assembly 1010 is used to drive the heating turntable 800 to rotate around its own rotation axis. The first drive assembly 1010 drives the heating turntable 800 to rotate around its own rotation axis, so that the heating turntable 800 can rotate relative to the frame 600, and can also make the first heating chamber 811 opposite to the small-diameter end of the feeding funnel 910. Specifically, the first drive assembly 1010 can be driven by a motor or a cylinder, which is not limited to this.

[0066] See also Figure 2The low-spill, direct-access bulk lunar soil sample receiving device provided in one embodiment of the present invention also includes a second drive assembly 1020 connected to the heating turntable 800. When the lunar soil in the sampling shovel slides through the feeding funnel 910 into the first heating chamber 811, the sampling shovel can send a third electrical signal to the controller, causing the controller to control the second drive assembly 1020 to rotate and raise the first heating table 810 to a third preset position. When the lunar soil in the sampling shovel has completely entered the first heating chamber 811, the second drive assembly 1020 drives the first heating table 810 to rotate and raise it to the third preset position, allowing the first heating table 810 to be covered by the chamber wall of the heating furnace within the low-spill, direct-access bulk lunar soil sample receiving device. This allows the first heating table 810 and the lunar soil within it to be contained in a sealed heating space, facilitating subsequent heating of the lunar soil and analysis of its volatile components. Specifically, the second drive assembly 1020 can be driven by a motor or a cylinder, without limitation.

[0067] See also Figure 1 and Figure 12-17 The low-spillage direct-access bulk lunar soil sample receiving device provided in one embodiment of the present invention also includes a second feeding assembly and a sample transport tube 700. The second feeding assembly includes a feeding base 100 connected to the frame 600, and the feeding base 100 is configured with a second feeding cavity 110; the sample tube 700 is electrically connected to the controller, and the sample tube 700 is configured with a sample cavity 710, and the sample cavity 710 is provided with a collector 720, which is used to carry lunar soil; the sample tube 700 can move closer to or away from the feeding base 100, and one end of the sample tube 700 can at least partially extend into the second feeding cavity 110; the heating turntable 800 also includes a second heating table 820, and the second heating table 820 and the first heating table 810 are arranged at intervals along the circumference of the heating turntable 800; when the sample tube 700 approaches the feeding base 100 and moves to the fourth preset position, the sample tube 700 can perform a sample spitting operation to separate the collector 720 from the sample tube 700, and pass through the feeding base 100 to cooperate with the second heating table 820.

[0068] Since the sample tube 700 is provided with a collector 720 containing lunar soil collected from the moon, the sample tube 700 is moved closer to the feed base 100 so that one end of the sample tube 700 can at least partially extend into the second feed cavity 110 of the feed base 100. When the sample tube 700 moves relative to the feed base 100 to the fourth preset position, the sample tube 700 performs a sample discharging operation, allowing the collector 720 to separate from the sample tube 700 and pass through the feed base 100 to cooperate with the second heating stage 820. During this process, each time the sample tube 700 performs a sample dispensing operation, it is in the fourth preset position relative to the feed base 100. Therefore, the position of the sample tube 700 relative to the feed base 100 remains consistent, and thus the position of the sample tube 700 relative to the second heating stage 820 also remains consistent. Consequently, after the collector 720 is separated from the sample tube 700, the collector 720 moves a specific distance to mate with the second heating stage 820. Because the movement distance of the collector 720 is relatively constant, the collector 720 and the second heating stage 820 mate well, making it less likely for lunar soil to spill from the collector 720's carrying chamber. Ultimately, the difference in lunar soil content within each collector 720 is minimal, resulting in more accurate experimental results with less error.

[0069] It should be noted that the lunar soil content in a collector 720 is only 200 ± 20 mg, which is very small. Therefore, if the lunar soil in the collector 720 leaks from the carrying chamber during transportation, it will significantly affect the accuracy of the experimental results. However, the present sample transport device can minimize this situation, ensuring that the difference in lunar soil content in each collector 720 is small, and the experimental results are more accurate and have a smaller error.

[0070] In one specific embodiment, a snap-fit ​​portion is constructed on the second heating platform 820, and the collector 720 is recessed inward along its axial direction to form a snap-fit ​​groove, and the collector 720 and the second heating platform 820 are matched by the snap-fit ​​action between the snap-fit ​​portion and the snap-fit ​​groove.

[0071] See also Figures 8-10 、 Figure 12-14 and Figure 16-17The low-spillage, direct-access bulk lunar soil sample receiving device provided by one embodiment of the present invention also includes a detection component 200 electrically connected to the controller. The detection component 200 is installed on the feed base 100. When the sample tube 700 approaches the feed base 100 and moves to a fourth preset position, the detection component 200 can detect the sample tube 700 and send a fourth electrical signal to the controller, so that the controller controls the sample tube 700 to perform a sample discharge operation. When the sample tube 700 moves closer to the feed base 100 and moves to the fourth preset position, the detection component 200 can detect that the sample tube 700 is in the fourth preset position and then send a fourth electrical signal to the controller. After receiving the fourth electrical signal, the controller controls the sample tube 700 to perform a sample discharge operation, so that the collector 720 separates from the sample tube 700 and then passes through the feed base 100 to cooperate with the second heating stage 820.

[0072] Please continue reading Figures 8-10 、 Figure 12-14 and Figure 16 One embodiment of the present invention provides two detection assemblies 200, which are radially opposed to each other along the feed base 100. Due to the provision of two detection assemblies 200, if one detection assembly 200 fails, the other detection assembly 200 can function and send a fourth electrical signal to the controller, making the device more fault-tolerant. This makes it particularly convenient and hassle-free when conducting experiments on the moon, where component replacement is difficult.

[0073] See also Figures 8-10 and Figure 16-17 , the detection assembly 200 of the sample conveying device provided by one embodiment of the present invention includes a first mounting seat 210, a first sensing member 220 and a detection plate 230; the first mounting seat 210 is fixedly connected to the frame 600, the first sensing member 220 is fixedly connected to the first mounting seat 210 and electrically connected to the controller, the detection plate 230 is slidably connected to the first mounting seat 210, and the detection plate 230 can at least partially extend into the second feeding cavity 110; when the sample tube 700 moves to the fourth preset position relative to the feeding seat 100, the sample tube 700 can abut against the detection plate 230 and drive the detection plate 230 to slide relative to the first mounting seat 210, so that the detection plate 230 abuts against the first sensing member 220; when the detection plate 230 abuts against the first sensing member 220, the first sensing member 220 can send a fourth electrical signal to the controller, so that the controller controls the sample tube 700 to perform a sample discharging operation.

[0074] When the sample tube 700 moves to the fourth preset position relative to the feeding seat 100, the sample tube 700 abuts against the detection plate 230 extending into the second feeding cavity 110 and drives the entire detection plate 230 to slide relative to the first mounting seat 210, so that the detection plate 230 can abut against the first sensing element 220, and then the first sensing element 220 sends a fourth electrical signal to the controller.

[0075] See also Figure 10 The detection plate 230 of the sample conveying device provided by one embodiment of the present invention includes a first detection arm 231 and a second detection arm 232 set at an angle; the first detection arm 231 is movably mounted on the second detection arm 232, and the first detection arm 231 at least partially extends into the feeding seat 100; the second detection arm 232 passes through the first mounting seat 210 and is slidably connected to the first mounting seat 210; when the sample delivery tube 700 moves to the fourth preset position relative to the feeding seat 100, the sample delivery tube 700 can abut against the first detection arm 231, and drive the first detection arm 231 and the second detection arm 232 to move along the axial direction of the feeding seat 100, so that the second detection arm 232 abuts against the first sensing element 220. Specifically, the axial direction of the feeding seat 100 is Figure 10 The yy' direction in .

[0076] Because the detection plate 230 includes a first detection arm 231 and a second detection arm 232 arranged at an angle, when the sample tube 700 moves to the fourth preset position, the sample tube 700 abuts the first detection arm 231, driving the first detection arm 231 to move axially along the feeding base 100. The second detection arm 232 then moves synchronously with the first detection arm 231, thereby causing the second detection arm 232 to abut against the first sensing member 220. At the same time, because the first detection arm 231 is movably mounted on the second detection arm 232, the first detection arm 231 has a certain amount of movement when driving the second detection arm 232 to move axially along the mounting base. Compared to a detection plate 230 formed by a fixed connection between the first and second detection arms 231, 232, the entire detection plate 230 is less likely to break and has a longer service life.

[0077] In one embodiment, a second sensing element 240 is directly configured on the second detection arm 232. When the second sensing element 240 abuts the first sensing element 220, the first sensing element 220 can send a fourth electrical signal to the controller. In another embodiment, the first sensing element 220 is a gravity sensing element. When the second detection arm 232 directly abuts the first sensing element 220, the first sensing element 220 can send a fourth electrical signal to the controller.

[0078] See also Figure 10 and Figure 17The second detection arm 232 of the sample conveying device provided by one embodiment of the present invention includes a first step portion 2321, a second step portion 2322 and a third step portion 2323 connected in sequence; and the diameters of the first step portion 2321 and the third step portion 2323 are larger than the diameter of the second step portion 2322; a stepped hole 211 is constructed in the first mounting seat 210, and the second step portion 2322 is at least partially accommodated in the stepped hole 211, and the first detection arm 231 is movably mounted on the second step portion 2322 and can abut against the first step portion 2321; the detection assembly 200 also includes a first elastic member 250 mounted on the outer periphery of the second step portion 2322, and the first elastic member 250 is in a compressed state and abuts between the third step portion 2323 and the stepped wall of the stepped hole 211.

[0079] By arranging the first elastic member 250 in a compressed state between the third step portion 2323 and the step wall of the step hole 211, the first elastic member 250 can apply an elastic force to the third step portion 2323 relative to the mounting seat away from the first detection arm 231, thereby making the third step portion 2323 and the first sensing member 220 in a separated state when the sample tube 700 is not in the fourth preset position.

[0080] It should be noted that the first detection arm 231 is movably mounted on the second stepped portion. When the sample delivery tube 700 is in the fourth preset position, the sample delivery tube 700 drives the first detection arm 231 along the axial direction of the feeding seat 100 and automatically moves. Figure 10 The y in the figure moves toward the y' direction, so that the first detection arm 231 contacts the first step portion 2321. At this time, through the principle of lever, the first detection arm 231 drives the entire second detection arm 232 to overcome the elastic force of the first elastic member 250 and moves along the axial direction of the feeding seat 100. Figure 10 The y in the figure moves toward the y′, and finally the second sensing element 240 installed on the third step portion 2323 abuts against the first sensing element 220, so that the first sensing element 220 sends the fourth electrical signal to the controller.

[0081] It should be noted that the second sensing element 240 can be directly integrated on the third stepped portion 2323 or fixedly connected to the third stepped portion 2323 , and there is no special limitation on this.

[0082] See also Figure 8 、 Figure 9 、 Figure 11 、 Figure 13 and Figure 14The low-spillage, direct-access bulk lunar soil sample receiving device provided in one embodiment of the present invention also includes at least two opposingly disposed rebound assemblies 300 connected to the frame 600. The at least two rebound assemblies 300 are disposed on the side of the feed base 100 facing away from the second feed chamber 110. The rebound assemblies 300 abut against the feed base 100 and are capable of driving the feed base 100 to move radially. The provision of two rebound assemblies 300 drives the feed base 100 to move radially, thereby facilitating insertion of the sample tube 700 into the second feed chamber 110. In one specific embodiment, to ensure a good seal, the clearance between the sample tube 700 and the second feed chamber 110 is 5 mm. The rebound assemblies 300 drive the movement of the feed base 100, facilitating insertion of the sample tube 700 into the second feed chamber 110.

[0083] See also Figure 11 The rebound assembly 300 of the sample conveying device provided by one embodiment of the present invention includes a second mounting seat 310, a second elastic member 320 and an abutment member 330; the second mounting seat 310 is fixedly connected to the frame 600, one end of the second elastic member 320 is connected to the second mounting seat 310, and the other end of the second elastic member 320 is connected to the abutment member 330, and the abutment member 330 is fixedly connected to the outer wall of the feeding seat 100 away from the second feeding cavity 110; the second elastic member 320 is in a compressed state, and the second elastic member 320 can drive the abutment member 330 to move along the radial direction of the feeding seat 100, so as to drive the feeding seat 100 to move along its own radial direction.

[0084] Through the elastic deformation ability of the second elastic member 320 itself, the abutment member 330 is driven to move radially along the feeding seat 100, so that the feeding seat 100 fixedly connected to the abutment member 330 moves along its own radial direction to facilitate the sample tube 700 to extend into the second feeding cavity 110.

[0085] It should be noted that the abutment 330 and the feeding seat 100 can be processed as one piece, or they can be processed separately and fixedly connected by bolt connection or welding. There is no limitation on this. As long as the second elastic member 320 drives the abutment 330 to move, the feeding seat 100 can move synchronously.

[0086] See also Figure 11 The resilient assembly 300 of the sample transport device provided in one embodiment of the present invention further includes a first connecting post 340 and a second connecting post 350. The first connecting post 340 is fixedly connected to the second mounting base 310, and the second connecting post 350 is fixedly connected to the abutment member 330. One end of the second elastic member 320 is connected to the first connecting post 340, and the other end of the second elastic member 320 is connected to the second connecting post 350.

[0087] See also Figure 1-Figure 2 and Figure 5-Figure 7 The sample transport device provided in one embodiment of the present invention further includes a cover plate 400, which is rotatably connected to the frame 600. The cover plate 400 has a closed state and an open state relative to the feed base 100 and the feed funnel 910. In the closed state, the cover plate 400 covers the side of the feed base 100 away from the second heating stage 820 and engages with the feed base 100 to restrict radial movement of the feed base 100. In the open state, one end of the sample delivery tube 700 can at least partially extend into the second feed cavity 110, and the lunar soil carried by the sampling shovel can slide into the first feed cavity 911 of the feed funnel 910. When the sample transport device is transported from Earth to the Moon and lands on the Moon, the cover plate 400 is in the closed state. This prevents large lunar dust from entering the first and second feed cavities 911 and 110 due to the strong impact force during landing, thereby reducing contamination of the surface of the second heating stage 820. At the same time, in this state, the elastic component can also limit the shaking of the feeding seat 100, so that the entire device is more stable and less prone to damage.

[0088] See also Figure 7 In one specific embodiment, the cover plate 400 is provided with a limiting portion 410 protruding outward along its axial direction; in the closed state, the limiting portion 410 can be engaged with the feeding seat 100, thereby limiting the feeding seat 100 from moving in its radial direction.

[0089] See also Figure 8 、 Figure 10 and Figure 11 The low-spillage direct-access bulk lunar soil sample receiving device provided by one embodiment of the present invention also includes an induction coil assembly 500, which is installed between the feeding base 100 and the heating turntable 800 and is electrically connected to the controller; when the collector 720 passes through the induction coil assembly 500 and cooperates with the heating turntable 800, the induction coil assembly 500 can send a fifth electrical signal to the controller, so that the controller controls the second heating table 820 to rotate and rise to the fifth preset position.

[0090] By setting up the induction coil assembly 500, when the collector 720 passes through the induction coil assembly 500, the induction coil assembly 500 can send a fifth electrical signal to the controller, so that after the collector 720 cooperates with the second heating platform 820, the controller controls the second heating platform 820 to rotate and rise to the fifth preset position, so that the second heating platform 820 and the collector 720 can be covered by the cavity wall of the heating furnace and form a sealed heating space. At this point, the lunar soil in the collector 720 is heated to study the volatile components of the lunar soil.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
