9. The rock breaking and sampling device for geological exploration according to claim 5, wherein: the movable table inner buckles (305) are movably clamped into the movable rod inner slots (404) through movable rod top slots (406) and movable rod outer arc slots (405).

10. A sampling method of a rock breaking sampling device for geological exploration according to any one of claims 1 to 9, wherein: the sampling method comprises the following steps:

(A) Placing the device at the position of geological soil or rock to be sampled, horizontally placing four support rods (205) on the ground, keeping the device in a stable and parallel state with the ground, injecting hydraulic oil into the hydraulic cylinder (101) through the oil delivery pipe (102) positioned above, and enabling the hydraulic oil to push the sealing plate (105) to move downwards, so that the hydraulic rod (103) and the connecting rod (104) drive the rotating mechanism (3) and the crushing mechanism (4) to move downwards, and enabling the crushing drill bit (403) to contact with the ground;

(B) Starting a servo motor (301), enabling the servo motor (301) to drive a rotating shaft (302) to rotate, enabling a movable table (303) to drive a movable rod (401) to rotate, enabling a crushing drill bit (403) to rotate on the surface of the ground, continuously injecting hydraulic oil into the hydraulic cylinder (101) through an oil delivery pipe (102) above, enabling the crushing drill bit (403) to keep rotating to move downwards, crushing soil or rock through the crushing drill bit (403), and after the sampling bucket (501) is completely immersed into the soil or rock along with the crushing drill bit (403), enabling the crushed soil or rock through the crushing drill bit (403) to be upwards transmitted through threads on the outer surface of a threaded column (402) and then fall into the sampling bucket (501), so that the soil or rock is collected and sampled through the sampling bucket (501);

(C) After the sampling barrel (501) is collected, the servo motor (301) is closed, the crushing drill bit (403) stops rotating, then hydraulic oil is injected into the hydraulic cylinder (101) through the oil delivery pipe (102) positioned below, the hydraulic oil is pushed to lift the sealing plate (105) back, the crushing drill bit (403) is returned to the ground, a worker steps on the pedal (505) by feet, the pedal (505) drives the spring column limit buckle (504) to move downwards, the spring column (502) extrudes the compression spring (503) to be clamped into the inner part of the loop bar inner groove (508), and after the spring column ejector rod (509) is completely moved out of the inner part of the movable table inner groove (307), at this time, the movable table inner buckle (305) is clamped into the movable rod outer arc groove (405) from the inside of the movable rod inner groove (404), the crushing mechanism (4) is rotated, the movable table inner buckle (305) is clamped into the movable rod top groove (406) from the inside of the movable rod outer arc groove (405), then the rotating mechanism (3) is pulled out upwards, the rotating mechanism (3) and the crushing mechanism (4) are separated, so that the device can directly take down the crushing mechanism (4) from the bottom end surface of the rotating mechanism (3), and then the sampling barrel (501) is pulled out upwards from the surface of the movable rod (401), so that the soil or rock in the movable table inner buckle is taken out, and the next detection is performed.
