Problems solved by technology

On the moon, due to the effects of vacuum, weightlessness, and large temperature changes, coupled with the impact of the limited transport capacity of the lander, it is difficult for drilling equipment to provide a large propulsion force, and it is difficult to replace the drill bit if it is stuck or damaged.
At the same time, it is difficult for the lunar lander to provide a lot of power to the auxiliary equipment, which brings great difficulties to the drilling of lunar rocks

Abstract

A low-power microwave coring machine suitable for lunar rocks and its use method, including an equipment platform on which a support frame front plate and a support frame rear plate are slidably installed, and the rear end surface of the support frame rear plate is installed on the equipment The front end of the microwave generator on the platform is connected, and the rear end of the microwave generator is connected with the fixed waveguide, the rotating waveguide, the power divider and the drill barrel in turn. The drill barrel is equipped with a high-precision slip ring structure, and the outer wall of the rotating waveguide and the drill barrel is equipped with gear ferrules. , the gear ferrule meshes with the transmission gear installed on the rotating shaft, and the rotating shaft is connected to the rotary drive; the rear end of the excavation drive is fixed on the equipment platform, and the front end is connected to the rear plate passing through the support frame and the front plate of the support frame. The synchronous movement of the microwave system and the drill barrel is realized, which meets the requirement of miniaturized equipment and low power to drill hard rocks, and can avoid the problems of immobile drilling and drill sticking; through the multi-port millimeter-wave irradiation of the power divider, the out-of-core The ring is completely broken, but the core is not broken.

Description

technical field [0001] The invention belongs to the technical field of rock drilling, and in particular relates to a low-power microwave coring machine suitable for lunar rocks and a use method. Background technique [0002] Rotary drilling of hard rock is to drill forward through the torque and thrust applied to the drill bit by the drilling rig, but because of the hard rock, it often encounters the problems of drill sticking, drilling immobility and severe wear of the drill bit, especially sticking drill It will seriously affect the construction progress. [0003] The drilling of lunar rock layer materials is of great significance for the study of lunar resources. At present, the drilling work of the moon is mainly aimed at the loose covering layer on the surface of the moon - the lunar regolith, and the rock blocks mixed in the lunar regolith and the lunar rocks existing under the lunar regolith have high strength. On the moon, due to the effects of vacuum, weightlessne...
