[0021] By setting the microwave radiation device to be multi-dimensionally rotatable, that is, operating the first hydraulic cylinder and the second hydraulic cylinder can make its radiation assembly rotate in the horizontal direction, and operating the first pitching hydraulic cylinder and the second pitching hydraulic cylinder can make the radiation assembly perform pitching rotation, facilitating the expansion of the radiation range of the rock to improve the subsequent collection efficiency.

The rock samples are further conveyed from the flexible connector to the spiral feeder through the transmission port, and then the rock samples are conveyed from the muck outlet to the muck collection bin;

[0024] By setting each group of solar modules to two and arranging the solar modules in a deployable form to form a large-area solar panel, sufficient energy can be obtained to ensure the normal operation of the lunar rover. Description of the Drawings

A cross-shaped impact frame is installed at the lower end of the cylinder. The cross-section of the impact frame is an isosceles triangle with the tip facing downwards. On one of the horizontal frames of the impact frame on the side inside the cylinder, a first check fan blade is rotatably supported by a first torsion spring shaft, and a second check fan blade is rotatably supported by a second torsion spring shaft. Both fan blades are semi-circular and symmetrically arranged. A transfer port is opened on the side wall of the movable housing corresponding to the opening. The end of the connecting rod away from the crank is connected to the outer wall of the top end of the movable housing through a hinge seat and drives it to slide in the vertical direction.
