[0015] Example: Figure 1-Figure 3 As shown, a core drilling device for geological exploration includes a lifting bracket 1, a drilling component is arranged in the lifting bracket 1, a lifting component is arranged on the drilling component, a fixing component is installed on the lifting bracket 1, the drilling component includes a motor 2 3, a spiral member 4 is fixedly installed on the output end of the motor 2 3, a spiral sheet is arranged on the spiral member 4, a drill bit is arranged on the bottom end of the spiral member 4, a sliding mounting plate is fixedly installed on the motor 2 3, and the sliding mounting plate is connected to the spiral member 4.

[0016] The lifting assembly includes a motor 2, which is fixedly mounted on the top of the lifting bracket 1. A screw rod 5 is fixedly mounted on the output end of the motor 2, the screw rod 5 is connected to the lifting bracket 1, and the screw rod 5 is threadedly matched with the sliding mounting plate. The lifting assembly also includes a sliding rod 9, which is fixedly mounted on the lifting bracket 1, the sliding rod 9 is connected to the sliding mounting plate, a scale is set on the sliding rod 9, and a distance sensor is also set on the sliding rod 9.

[0017] A circular hole 13 is provided on the bottom end of the lifting bracket 1, and a screw groove 14 is provided on the circular hole 13. The screw groove 14 cooperates with the screw on the screw member 4. A display 10 is also provided on the lifting bracket 1. The display 10 is used to display the distance that the sensor on the sliding rod 9 descends to the screw member 4.

[0018] The fixing assembly includes a mounting bracket 7, which is connected to the lifting bracket 1. The mounting bracket 7 is provided with two sets of symmetrically distributed connecting mechanisms. The connecting mechanisms include a hydraulic cylinder 6, which is fixedly mounted on the mounting bracket 7, and the cylinder arm of the hydraulic cylinder 6 is fixedly mounted on the lifting bracket 1.

[0019] The connecting mechanism also includes a hydraulic cylinder 2 8, which is fixedly mounted on the mounting bracket 7. A cone 11 for inserting into the ground and fixing is fixedly mounted on the cylinder arm of the hydraulic cylinder 2 8, and a plurality of wheels 12 for movement are evenly arranged at the bottom end of the mounting bracket 7.

[0020] Working principle: the device is moved to the position to be drilled by multiple wheels 12, and the hydraulic cylinder 28 is started. The cylinder arm of the hydraulic cylinder 28 drives the cone 11 to be inserted into the ground to prevent the mounting bracket 7 from moving during the drilling process. Then the hydraulic cylinder 16 is started, and the cylinder arm of the hydraulic cylinder 16 drives the lifting bracket 1 to move downward. When the bottom end of the lifting bracket 1 contacts the ground, the hydraulic cylinder 16 stops, and the motor 23 and the motor 12 are started at the same time. The output end of the motor 23 drives the screw 4 to rotate, and the output end of the motor 12 drives the screw 5 to rotate. The screw 5 drives the sliding mounting plate to move downward, and the sliding mounting plate drives the screw 4 to move downward.

After the screw 4 reaches the specified depth, if the display 10 After damage occurs, by observing the scale on the sliding rod 9 and recording the depth of the spiral member 4 descending, the motor 23 stops, the motor 12 stops, and the hydraulic cylinder 6 is started. The cylinder arm of the hydraulic cylinder 6 retracts to drive the lifting bracket 1 to move upward, and the lifting bracket 1 drives the spiral member 4 to move upward. The rock and soil of different depths will stay on the spiral blades of the spiral member 4. Then the staff collects the rock and soil of different depths on the spiral blades. After the collection is completed, the motor 2 is started, and the motor 2 is reversed. The output end of the motor 2 drives the sliding mounting plate to move upward through the screw rod 5, and the motor 23 is started, and the motor 23 is reversed. The motor 23 drives the spiral member 4 to reverse. The spiral blades on the spiral member 4 cooperate with the spiral blade grooves 14 to remove the remaining rock and soil on the spiral blades to ensure the service life and cleanliness of the device.
