[0025] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0026] With reference to Figures 1 to 16 , the double-station lunar soil transfer and heating extraction device of the present invention consists of three parts, namely, a sealing module 1, a heating extraction module 2, and a frame module 3. The lunar soil collected in the frame module 3 is heated by the heating extraction module 2 to volatilize effective detection components. The sealing module 1 is used for sealing during the operation of the heating extraction module 2, so that the components volatilized from the heating extraction module 2 can be transported to a designated detection device through a pre-set pipeline.

[0027] With reference to Figures 1 to 11 , the sealing module includes a press, a sealing cover driven by the press, and a volatile gas sampling tube communicated with the sealing cover. Specifically, the sealing module 1 includes a motor bracket 1-1, a left sealing bearing 1-2, a lead screw 1-3, a left sealing pin shaft 1-4, a left sealing connecting rod 1-5, a left rotating pin shaft 1-6, a sealing base 1-7, a linear bearing 1-8, a volatile gas sampling tube 1-9, a right rotating pin shaft 1-10, a right sealing connecting rod 1-11, a right sealing pin shaft 1-12, a left gear 1-13, a right sealing bearing 1-14, a right sliding connecting rod 1-15, a left sliding connecting rod 1-16, a right gear 1-17, and a sealing motor 1-18.

[0028] The sealing motor 1-18 is fixed to the motor bracket 1-1 by screws, and the right sealing bearing 1-14 is installed thereon. The lead screw 1-3, the left sealing pin shaft 1-4, the left sealing connecting rod 1-5, the left rotating pin shaft 1-6, the sealing base 1-7, the right rotating pin shaft 1-10, the right sealing connecting rod 1-11, the right sealing pin shaft 1-12, the right sliding connecting rod 1-15, and the left sliding connecting rod 1-16 form a linkage mechanism.

[0029] It is installed on the motor bracket 1-1 through the left sealing bearing 1-2 and the right sealing bearing 1-14 provided at both ends of the lead screw 1-3. And a left gear 1-13 is provided on the same side of the lead screw 1-3 and the right gear 1-17. The right gear 1-17 meshes with the left gear 1-13. The sealing motor 1-18 drives the right gear 1-17 to rotate, thereby driving the left gear 1-13 to rotate, and further driving the lead screw 1-3 to rotate.

[0030] The lead screw 1-3 is a bidirectional lead screw, with helices of different helix directions machined on its left and right sides. The sliding link right 1-15 and the sliding link left 1-16 meshing with the lead screw 1-3 also have different helix directions. When the lead screw 1-3 rotates, it drives the sliding link right 1-15 and the sliding link left 1-16 arranged on the lead screw 1-3 to move towards or away from each other. When the sliding link right 1-15 and the sliding link left 1-16 move towards or away from each other, they drive the sealing base 1-7 to move up and down through the linkage mechanism. A volatile gas sampling tube 1-9 is arranged on the sealing base 1-7, and the volatile gas sampling tube 1-9 is connected to the motor bracket 1-1 through a linear bearing 1-8. When the sealing base 1-7 moves up and down, it drives the volatile gas sampling tube 1-9 to move up and down.

[0031] The heating and extraction module 2 is placed inside the frame module 3, and includes a horizontal sliding platform and at least one heating furnace vertically supported on the horizontal sliding platform, having a double-station, namely a feeding station and an extraction station.

[0032] Specifically, with reference to Figures 12 to 14 , the heating and extraction module 2 includes a left bearing cover 2-1, a left bearing seat 2-2, a left heating and extraction bearing 2-3, a co-rotating lead screw 2-4, a heating base 2-5, a sliding nut 2-6, a right bearing cover 2-7, a station motor 2-8, a coupling 2-9, a right bearing cover 2-10, a right heating and extraction bearing 2-11, a right heat insulation base 2-12, a right flexible heat pipe 2-13, a right heating furnace 2-14, a right sealing ring 2-15, a left sealing ring 2-16, a left flexible heat pipe 2-17, a left heating furnace 2-18, a left heat insulation base 2-19, a left temperature sensor 2-20, a right temperature sensor 2-21, a left concave guide rail 2-22, a right concave guide rail 2-23, a left heating wire 2-24, and a right heating wire 2-25.

[0033] The co-rotating lead screw 2-4 is fixed on the left bearing seat 2-2 and the right bearing seat 2-7 through the left heating and extraction bearing 2-3 and the right heating and extraction bearing 2-11 arranged at both ends. A coupling 2-9 is arranged on the right side of the co-rotating lead screw 2-4 and is connected to the station motor 2-8 through the coupling. When the station motor 2-8 rotates, it can drive the co-rotating lead screw 2-4 to move. A sliding nut 2-6 is arranged on the co-rotating lead screw 2-4, and a heating base 2-5 is arranged on the sliding nut 2-6. The heating base 2-5 is equipped with a left concave guide rail 2-22 and a right concave guide rail 2-23, so as to ensure that the heating base 2-5 has only one degree of freedom of movement. Thus, when the station motor 2-8 drives the co-rotating lead screw 2-4 to rotate, the heating base 2-5 moves left and right.

[0034] A left heat insulation base 2-19 and a right heat insulation base 2-12 are arranged on the heating base 2-5, and a left heating furnace 2-18 and a right heating furnace 2-14 are arranged on the left heat insulation base 2-19 and the right heat insulation base 2-12 for heating the sample.

[0035] Inside the heating furnace, temperature sensors left 2-20 and temperature sensors right 2-21 are provided to display and control the heating temperature. Heating wires left 2-24 and heating wires right 2-25 are provided on the right 2-14 and left 2-18 of the heating furnace to heat the heating furnace. Flexible heat pipes right 2-13 and flexible heat pipes left 2-17 are provided on the right 2-14 and left 2-18 of the heating furnace to dissipate heat from the heating furnace after heating.

[0036] With reference to Figure 15 and Figure 16 , the frame module 3 includes a frame 3-1, a radiation plate right 3-2, a housing 3-3, a sample funnel 3-4, a radiation plate left 3-5, a convex guide rail left 3-6, and a convex guide rail right 3-7.

[0037] The sealing module 1 and the heating extraction module 2 are installed on the frame 3-1. The concave guide rail left 2-22 and the concave guide rail right 2-23 in the heating extraction module 2 are respectively engaged with the convex guide rail left 3-6 and the convex guide rail right 3-7 of the frame module 3 to realize the movement of the heating base 2-5 in the heating extraction module 2.

[0038] The sample enters the left 2-18 or right 2-14 of the heating furnace through the sample funnel 3-4 provided on the housing 3-3. Subsequently, the station motor 2-8 in the heating extraction module 2 rotates to drive the left 2-18 or right 2-14 of the heating furnace to move towards the sealing position. After reaching the sealing position, the sealing motor 1-18 of the sealing module 1 starts to rotate, driving the volatile gas sampling tube 1-9 to move downward.

[0039] Two sealing caps are processed on the volatile gas sampling tube 1-9 (the right sealing cap is solid). The sealing cap of the volatile gas sampling tube 1-9 is closely fitted with the sealing ring right 2-15 or the sealing ring left 2-16 provided on the left 2-18 or right 2-14 of the heating furnace to realize the sealing of the heating furnace. Subsequently, heating starts, and the effective components volatilized by heating are transported to the detection device through the volatile gas sampling tube 1-9 for detection. After detection, the heat is quickly transferred to the radiation plate right 3-2 or the radiation plate left 3-5 through the flexible heat pipes arranged around the heating furnace to quickly radiate the heat and prevent it from affecting the next detection.

[0040] The above are only embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
