Problems solved by technology
[0004] The traditional rotary feed scheme adopts the working principle of energy storage impact vibration + rotary cutting, and the driving device adopts the working principle of 1 rotary device + 1 feeding device + 1 impact device, and uses rotary drilling to drill chips and is equipped with chip removal / The sampling path is used for sample transport, but in the current rotary transfer scheme, the cutting, chip removal and sampling functions are all set separately, the robotic arm needs to be equipped with in-hole sampling tools, the overall device mass is relatively large, and the supporting force of the robotic arm is relatively high. High, the excavation speed of a single cutting edge is slow, the degree of wear is high, and the long-term operation results in high heat generation. At the same time, the sensor effect of the integrated property is poor, and the chip removal path is long, resulting in a large thermal disturbance to the lunar soil water and ice objects.

The invention discloses a line cutting tunneling sampler for collecting lunar soil water ice, relates to the technical field of solid sample and volatile matter sampling, and solves the problems that in a current rotary feeding scheme, the device is large in mass, the tunneling speed of a single cutting edge is low, the abrasion degree is high, and the calorific value is high due to long-time operation; the lunar soil water and ice object thermal disturbance device comprises a double-chain saw cutting mechanism, a driving transmission mechanism, a rack shell and a supporting frame, and a first chain saw cutting mechanism and a second chain saw cutting mechanism of the double-chain saw cutting mechanism are driven through the driving transmission mechanism; each cutting chain link of the double-chain saw cutting mechanism is provided with a cutting edge used for cutting samples and a chip containing cavity located on the edge side of the cutting edge and used for containing and conveying the samples, and a floating rotating shaft is connected between the first chain saw cutting mechanism and the second chain saw cutting mechanism. Heat can be taken away in time, and thermal disturbance to lunar soil water ice objects is small.
Description
technical field [0001] The invention relates to the technical field of solid samples and volatile matter sampling, in particular to a line cutting tunneling sampler used for collecting lunar soil water ice. Background technique [0002] With the advancement of aerospace technology, in order to realize the development and utilization of lunar resources, landing on the moon and collecting lunar soil has become a development trend. Lunar soil sampling needs to overcome the high vacuum, high temperature, low temperature, and large temperature difference between high and low temperatures on the moon. In the case of problems such as large moon dust and light gravity, the lunar soil is collected as it is. The lunar soil is rich in elements such as hydrogen, helium, neon, argon, and nitrogen formed by the accumulation of solar wind particles. They can all be released when heated to a temperature above 700°C. Among them, chlorine-3 gas is an efficient fuel for nuclear fusion reactio...
