1. A low-power microwave coring machine suitable for lunar rocks, comprising: a drill drum, a microwave generator, a high-precision slip ring structure, a rotary waveguide, a microwave generator, a rotary driver, two tunneling drivers, an equipment platform, equipment slide rails and a support framework,
wherein the equipment slide rails are symmetrically arranged on the equipment platform, a support framework front plate and a support framework rear plate are mounted on the equipment slide rails in a sliding manner, a rear end surface of the support framework rear plate is connected with a front end of the microwave generator, the microwave generator is mounted on the equipment platform in a sliding manner, a rear end of the microwave generator is connected with one end of a fixed waveguide, and the other end of the fixed waveguide is rotationally mounted at a rear end of the rotary waveguide; the rotary waveguide as a change-over device rotates itself and rotates and transmits microwaves from the fixed waveguide in a lossless manner; a front end of the rotary waveguide is connected with a rear end of a power divider, a front end of the power divider is connected with a rear end of the drill drum through coaxial cables, and a front end of the drill drum is in contact with a rock stratum; the high-precision slip ring structure sleeves an excircle of the drill drum, and lossless collection of reflection signals of the power divider under a rotary condition is realized; the rotary waveguide is located in a through hole in a top of the support framework rear plate, and the rotary waveguide can rotate in the through hole in the support framework rear plate; the drill drum is located in a through hole in a top of the support framework front plate, and the drill drum can rotate in the through hole in the support framework front plate; a gear ferrule is arranged on both of an outer wall of the rotary waveguide and an outer wall of the drill drum, and the gear ferrules are both located at a front end of the support framework rear plate and a front end of the support framework front plate which are in corresponding arrangement; a transmission gear engaged with the corresponding gear ferrule is arranged below each gear ferrule, the two transmission gears are both in key connection with a rotary shaft, a front end of the rotary shaft penetrates through a through hole in a middle of the support framework front plate and is in key connection with one of the transmission gears, a rear end of the rotary shaft is in key connection with the other transmission gear and penetrates through a through hole in a middle of the support framework rear plate to be connected with an output end of the rotary driver; the rotary driver is fixedly mounted on the support framework rear plate through bolts, the gear ferrules are driven by the transmission gear of the rotary driver to rotate, and further the rotary waveguide, the power divider and the drill drum are driven to rotate together; and a rear end of each tunneling driver is connected with a corresponding tunneling driver base, the tunneling driver bases are fixed on the equipment platform, a front end of each tunneling driver penetrates through a through hole in a middle and lower part of the support framework rear plate to be connected with the support framework front plate, the tunneling drivers propel the support framework front plate to apply propelling force on the drill drum, and the two tunneling drivers are symmetrically arranged by using the drill drum as a symcenter.
