Principle of operation
(1) The adhesive tape 4 is used as a collecting carrier, and the sampling is carried out by sticking (or adsorbing)
When the detector gradually falls down to the target surface, the detector extends out of the sampler to be contacted with the surface of the celestial body, and when the sampler is contacted with the surface, the star soil is adhered to the surface of the adhesive tape in a sweeping mode through the adhesive tape 4.
(2) The adhesive tape 4 absorbs the sample and is also used as a transmission carrier
The collected sample is brought into the collection roll through the continuous movement of the adhesive tape 4, and the adhesive tape collection roll plays a role in fixing and sealing the collected sample.
(3) Double-wheel cooperative driving to realize repeated sampling
The adhesive tape 4 is driven by two motors of the unwinding wheel 2 and the winding wheel 3, and the two-dimensional code layer 41 on the back of the adhesive tape can realize the actions of advancing, retreating, repeated friction and the like of the adhesive tape 4, so that repeated sampling can be realized. One of the two motors is driven, and the other motor is driven and provides a certain reverse force to ensure that the adhesive tape 4 is always kept in a tension state when moving.
(4) The design of the partitioned adhesive tape 4 is suitable for different sampling objects
The lower surface of the adhesive tape 4 adopts a partition design, and different collection functions are realized in different areas: if the planet surface is loose floating dust, the colloid area can be used for directly carrying out adhesion and collection; if the planet surface is smaller weathered layer particles, the particles can be adsorbed and collected by using the barb region; if the surface of the planet is a hard rock layer, the surface layer can be polished in a sand paper area and then the surface layer is adhered and collected in a colloid area, so that the planet sampling device can adapt to different sampling objects.
(5) Contact area and pressure intensity can be adjusted to improve adaptability to sampling object

The pressing mechanism 8 is mainly used for adjusting the relative position of the 2 guide wheels 84 and applying certain pressure to the surface of the adhesive tape 4 to ensure that the adhesive tape is in good contact with the surface of the extraterrestrial celestial body, so that the adhesion strength during sticking is ensured. The guide wheel 84 is mainly used to ensure a smooth movement of the adhesive tape 4.
(6) Real-time sensing technology for motion position and surface adhesion density of adhesive tape
The two-dimensional code recognizer 9 is used for feeding back the movement position of the adhesive tape 4 in real time. The sample detector is used for detecting the adhesion density of the surface of the adhesive tape 4 in real time and feeding back a signal to the take-up reel 3 in real time. When the adhesion density is low, the conveying speed of the adhesive tape 4 is reduced; when the adhesive substance is not detected on the surface of the adhesive tape 4, the collection is automatically stopped, and the waste of the adhesive tape 4 is prevented.
