Classification: CPC E  H | IPC E  H

Claim 4:
5. The low-power microwave coring machine according to claim 1, wherein the high-precision slip ring structure comprises rotor signal lines, high-precision slip ring rotors, high-precision signal carbon brushes, high-precision slip ring stators and high-precision stator signal lines, wherein the high-precision slip ring rotors sleeve the excircle of the drill drum and synchronously rotate with the drill drum, each rotor signal line is connected to the corresponding high-precision slip ring rotor, the rotor signal lines are respectively connected with the four corresponding insulating and protecting ends through a signal converter, each high-precision slip ring rotor is rotationally connected with the corresponding high-precision slip ring stator through the corresponding high-precision signal carbon brush, the high-precision slip ring rotors rotate along with the drill drum, but the high-precision slip ring stators and the high-precision signal carbon brushes do not move, signals of the high-precision slip ring rotors are transmitted into the high-precision slip ring stators in a lossless manner through the high-precision signal carbon brushes, reflection wave signals are transmitted into a controller of the microwave generator through the high-precision stator lines, the controller controls the microwave generator in the low-power microwave coring machine to switch on and switch off, and microwave parameters are adjusted at any time through the reflection wave signals fed back by the high-precision slip ring structure.
