Description

Technical Field

[0001] The present invention relates to the field of lunar soil sample processing mechanisms, and particularly to a dust-removing sliding shoe type rotary stopping and guiding mechanism and a volatile matter preparation device. Background Art

[0002] Deep space exploration refers to the exploration activities carried out by humans on the moon and more distant celestial bodies or space environments. As an important direction of human space activities and an important way of space science and technology innovation, it is one of the development priorities in the current and future space fields. Deep space exploration is not only a reflection of a country's scientific and technological level, but also a reflection of its comprehensive national strength. At present, China's fourth phase of lunar exploration has successfully completed the lunar soil sampling and return mission for the first time, which has made great contributions to deducing the lunar evolution history and scientific research. With the continuous update and iteration of technology, more celestial bodies and lunar soils will be studied in the future.

[0003] The volatile matter preparation and processing mechanism is the core extravehicular equipment of the lunar soil volatile matter measuring instrument, and its main function is to heat-treat lunar soil samples. However, during the lunar soil collection and processing process, the adhesion of lunar dust on the processing mechanism is inevitable. When lunar dust adheres to the frame guide rail, it will cause jamming and wear during the reciprocating motion of the traditional sliding shoe type rotary stopping and guiding mechanism, resulting in equipment failures. In severe cases, derailment will occur. These situations often lead to a significant reduction in the service life of the guiding system and a significant increase in the failure rate, affecting the work of lunar soil sample processing. Therefore, an agency with a dust-removing function is needed to remove the lunar dust on the agency guide rail during lunar soil sample processing to ensure the normal operation of the agency.

Specific embodiments

[0032] The following further elaborates on the specific embodiments of the present invention with reference to the accompanying drawings:

[0033] Specific embodiment one: Refer to Figure 1-7 This embodiment is described. A dust-removing sliding shoe type rotary stopping and guiding mechanism described in this embodiment includes a plurality of sliding shoes 1, a bracket, and a dial plate 5. The bracket is connected to a lead screw 7, and the lead screw 7 is driven by a driving motor 8 through a gear to extend towards the direction of the induction heating furnace 9. When the lead screw 7 extends forward, it pushes the bracket to move forward together.

[0034] A plurality of sliding shoes 1 and a dial plate 5 are installed on the bracket; the sliding shoes 1 cooperate with the machine frame 11, and the machine frame 11 is used as a slide rail to form a guiding mechanism; a dust-removing layer 12 is provided on each sliding shoe 1, and during the process of the dust-removing sliding shoe type rotary stopping and guiding mechanism moving back and forth on the machine frame 11, the dust-removing layer 12 is used to remove the lunar dust adhering to the machine frame 11; the dial plate 5 plays a limiting role on the furnace cover conversion mechanism 10 to realize the rotary stopping function of the furnace cover conversion mechanism 10.

[0035] The sliding shoe 1 further includes a guiding groove 15, a dust-removing layer 12 is provided on the guiding groove 15, and the guiding groove 15 cooperates with the machine frame 11.

When the lead screw 7 extends, it pushes the support plate connecting seat 3 to move together. A dial plate 5 is also installed on the support plate connecting seat 3. When the furnace cover conversion mechanism 10 is driven to rotate forward by the swing motor 14, the dial plate 5 will not affect the rotation of the furnace cover conversion mechanism 10. However, when the furnace cover conversion mechanism 10 is driven to rotate reversely by the swing motor 14, the dial plate 5 will come into contact with the furnace cover conversion mechanism 10 to prevent the furnace cover conversion mechanism 10 from continuing to rotate. That is, a structure with the same function as a ratchet is formed between the furnace cover conversion mechanism 10 and the dial plate 5.

[0038] Two sliding shoes 1 are installed below the motor seat 2, and two sliding shoes 1 are installed above the bearing seat 4; the sliding shoes 1 cooperate with the frame 11 to use the frame 11 as a slide rail to realize the mechanism guiding function and share part of the weight of the furnace cover conversion mechanism 10.

[0039] A bearing 6 is installed on the bearing seat 4, and the furnace cover conversion mechanism 10 is installed on the bearing seat 4 through the bearing 6. The bearing 6 is a deep groove ball bearing.

[0040] A swing motor 14 is installed on the motor seat 2, and the output shaft of the swing motor 14 is connected to the furnace cover conversion mechanism 10 to drive the furnace cover conversion mechanism 10 to swing, realizing the function of replacing the furnace cover of the induction heating furnace 9 in the lunar soil sample processing mechanism.

[0041] The motor seat 2 and the bearing seat 4 are arranged opposite to each other to make the structure more compact.

[0042] A volatile matter preparation device adopting the above-mentioned dust-removing sliding shoe type rotary stop and guiding mechanism includes a dust-removing sliding shoe type rotary stop and guiding mechanism, a driving motor 8, a swing motor 14, a lead screw 7, a furnace cover conversion mechanism 10, a plurality of furnace covers 13, a heating furnace and a frame 11. The support plate connecting seat 3 is connected to the lead screw 7, and the lead screw 7 is driven by the driving motor 8 through a gear to expand and contract towards the direction of the heating furnace 9, driving the dust-removing sliding shoe type rotary stop and guiding mechanism and the furnace cover conversion mechanism 10 to perform reciprocating motion on the frame 11, so as to send the furnace cover 13 into and out of the heating furnace.

[0043] The furnace cover conversion mechanism 10 is installed on the bearing seat 4, the swing motor 14 is installed on the motor seat 2, and the swing motor 14 drives the furnace cover conversion mechanism 10 to swing; the guiding groove 15 cooperates with the frame 11 and uses the frame 11 as a slide rail to form a guiding mechanism; the dust-removing layer 12 cooperates with the frame 11 to remove the lunar dust on the frame 11; the dial plate 5 cooperates with the furnace cover conversion mechanism 10 to perform rotary stop on the furnace cover conversion mechanism 10; a plurality of furnace covers 13 are arranged on the furnace cover conversion mechanism 10, and the furnace cover conversion mechanism 10, the furnace cover and the heating furnace cooperate to prepare volatile matter; the heating furnace 9 is an induction heating furnace.

[0044] The specific working principle of the above-mentioned dust-removing sliding shoe type rotary stop and guiding mechanism and volatile matter preparation device is explained as follows:

[0045] When heating the star soil, the dust-removing sliding shoe type rotary stop and guiding mechanism is placed on the frame 11 through the sliding shoe 1, and the frame 11 is used as a slide rail to achieve the guiding function. The driving motor 8 drives the lead screw 7 to extend forward, thereby driving the dust-removing sliding shoe type rotary stop and guiding mechanism and the furnace cover conversion mechanism 10 to reciprocate on the frame 11, so as to achieve the purpose of sending the furnace cover 13 into and out of the furnace body of the induction heating furnace 9. During the reciprocating movement of the mechanism, the dust-removing layer 12 is used to remove dust from the slide rail with the frame 11 as the slide rail, ensuring the normal progress of the reciprocating movement of the mechanism. The swing motor 14 drives the furnace cover conversion mechanism 10 to achieve its swing action. During the swing of the furnace cover conversion mechanism 10, the swing stop function of the furnace cover conversion mechanism 10 is realized through the dial 5. When the furnace cover conversion mechanism 10 is driven to rotate forward by the swing motor 14, the dial 5 will not affect the rotation of the furnace cover conversion mechanism 10. When the furnace cover conversion mechanism 10 is driven to rotate reversely by the swing motor 14, the dial 5 will contact the furnace cover conversion mechanism 10 to prevent the furnace cover conversion mechanism 10 from continuing to rotate, that is, a structure with the same function as a ratchet is formed between the furnace cover conversion mechanism 10 and the dial 5, and the conversion between different furnace covers is realized through this structure.

[0046] Summarizing the above embodiments, for the dust-removing sliding shoe type rotary stop and guiding mechanism and volatile matter preparation device of the present invention, by adding the dust-removing layer 12, the star dust adhering to the slide rail is cleaned, reducing the risk of jamming caused by the adhesion of star soil during the movement of the traditional sliding shoe type rotary stop and guiding mechanism, prolonging the service life of the mechanism, improving the reliability of the star soil sample processing mechanism, and the overall structure is light in weight, high in precision, low in energy consumption, simple in structure, simple in operation and convenient in control; for the dust-removing sliding shoe type rotary stop and guiding mechanism and volatile matter preparation device of the present invention, it can use the provided sliding shoe 1 as a support to share part of the weight of the furnace cover conversion mechanism 10, and cooperate with the frame 11 to use the frame 11 as a slide rail to achieve the guiding function of the mechanism; for the dust-removing sliding shoe type rotary stop and guiding mechanism and volatile matter preparation device of the present invention, it can use the provided dust-removing layer 12 to remove the star dust adhering to the mechanism, ensuring the normal sliding of the mechanism; for the dust-removing sliding shoe type rotary stop and guiding mechanism and volatile matter preparation device of the present invention, the provided dial 5 can perform swing stop on the furnace cover conversion mechanism 10, so that the furnace cover 13 stops at a predetermined position.
