The propulsion drive screw drives the screw transmission nut together with the propulsion support slider to move along the propulsion moving slide groove. Multiple propulsion support sliders together drive the drilling drive casing to move along the axis direction of the propulsion mechanism casing, that is, the drilling direction of the main drill rod.

[0035] Description: The coring constraint mechanism can be used to well fix and constrain the cylindrical sample contained in the outer tube of the main drill pipe, so as to prevent the coring sample from falling off and being damaged from the outer tube of the main drill pipe. The inner rod of the radial constraint telescopic rod extends to drive the radial constraint driving plate to move along the driving slide plate receiving groove.

[0087] The additional constraint driving rod 274 is an electrically controlled telescopic rod, the outer rod end of the additional constraint driving rod 274 is fixedly connected to the inner wall of the additional constraint accommodating hole 271 , and the inner rod end of the additional constraint driving rod 274 is fixedly connected to the additional constraint elastic steel plate 273 .

[0088] Embodiment 4: Based on embodiment 3, Figure 4 As shown, an end of the propulsion mechanism casing 211 close to the main drill rod 23 is provided with an axis stabilizing mechanism 28. Fig.13 As shown, the axis stabilization mechanism 28 includes an axis stabilization support ring 281 fixed in the propulsion mechanism tube shell 211 and arranged coaxially therewith, and the inner side wall of the axis stabilization support ring 281 has a plurality of stabilization rod connection holes 282 extending along its radial direction, and each stabilization rod connection hole 282 is connected to an axis stabilization support rod 283, and the other ends of the plurality of axis stabilization support rods 283 are commonly connected to an axis stabilization constraint ring 284;

[0089] The axial center stabilization restraint ring 284 is coaxially arranged with the axial center stabilization support ring 281, and the main drill rod 23 is rotatably fitted in the axial center stabilization restraint ring 284;

[0090] The axial stabilization support rod 283 is an electrically controlled telescopic rod. The outer rod end of the axial stabilization support rod 283 is connected to the inner bottom end of the stabilization rod connecting hole 282 through a ball hinge, and the inner rod end of the axial stabilization support rod 283 is connected to the outer side surface of the axial stabilization constraint ring 284 through a ball hinge.

[0091] In the actual application process of the present invention, the entire equipment support is set up at the location where drilling and surveying are required, and multiple drilling support legs 12 can firmly support the entire equipment on the ground and align the main drill rod 23 with the drilling direction;

[0092] The main drill rod 23 is driven to rotate by the drilling drive mechanism 22, and the drilling drive motor 226 is turned on. The output shaft of the drilling drive motor 226 drives the drilling drive rotating shaft 222 to rotate through the drilling drive reducer 225, and the drilling drive rotating shaft 222 drives the drill rod connecting rod 223 to rotate together with the main drill rod 23;

[0093] The main drill rod 23 is driven by the drilling propulsion mechanism 21 to gradually move in the drilling direction, and the propulsion drive motor 217 drives the propulsion drive screw 215 to rotate through the propulsion drive transmission 218, and the propulsion drive screw 215 drives the screw drive nut 214 and the propulsion support slider 213 to move along the propulsion movement slide 2120;

[0094] The plurality of propulsion support sliders 213 together drive the drilling drive casing 221 to move along the axis direction of the propulsion mechanism casing 211, that is, the drilling direction of the main drill rod 23. The drilling drive casing 221, the drilling drive rotating shaft 222, the drill rod connecting rod 223 and the main drill rod 23 move together along the drilling direction as a whole, so that the main drill rod 23 is gradually drilled into the rock and soil layer.

[0095] In actual drilling survey, the tilt adjustment mechanism 25 can be used to adjust the orientation of the main drill rod 23 according to the actual required drilling direction, so that the main drill rod 23 is aligned with the predetermined drilling direction. The tilt drive motor 255 drives the tilt adjustment shaft 252 to rotate through the meshingly connected tilt adjustment active worm 256 and the tilt adjustment driven worm gear 254. The tilt adjustment shaft 252 then drives the propulsion mechanism casing 211 to rotate around the axis of the tilt adjustment shaft 252 to adjust the tilt orientation of the main drill rod 23.

[0096] In actual drilling survey, when coring the rock and soil layer, the coring constraint mechanism 26 can be used to well fix and constrain the cylindrical sample contained in the outer tube 231 of the main drill pipe to prevent the coring sample from falling off and being damaged from the outer tube 231 of the main drill pipe. The inner rod of the radial constraint telescopic rod 268 extends to drive the radial constraint driving plate 265 to move along the driving slide plate receiving groove 264. Under the mutual constraint and drive of the radial drive constraint groove 266 and the radial drive constraint column 267, the sliding connection column 262 moves along the axial direction of the direction constraint hole 2612. The sliding connection column 262 drives the coring constraint plate 263 to press and support the outer side of the cylindrical sample. Under the fixed constraint of multiple coring constraint plates 263, the cylindrical sample is firmly fixed and constrained in the outer tube 231 of the main drill pipe.

[0097] The coring restraint mechanism 26 is suitable for fixing and restraining relatively hard rock and soil layer samples;

[0098] For loose rock and soil layer samples, the additional constraint mechanism 27 is used to well fix and constrain the cylindrical sample contained in the outer tube 231 of the main drill pipe. The additional constraint mechanism 27 is arranged at one end close to the coring drill bit 230. The inner rod of the additional constraint driving rod 274 extends to drive the additional constraint elastic steel plate 273 to extend from the elastic steel plate constraint chute 272 at one end of the inner wall of the coring constraint support tube 261. The additional constraint elastic steel plate 273 is inserted into the cylindrical sample. Multiple pieces of additional constraint elastic steel plates 273 form a fixed constraint wall at one end close to the coring drill bit 230, which firmly fixes and constrains the cylindrical sample in the outer tube 231 of the main drill pipe to prevent the cylindrical sample from falling out from one end of the coring drill bit 230.

[0099] In actual drilling survey, the buffer connection mechanism 24 can absorb the impact vibration generated during the buffer drilling process, which is beneficial to maintaining the overall stability of the equipment. The impact vibration along the axis direction of the main drill rod 23 will cause the propulsion connection column 212 and the propulsion mechanism shell 211 to have a relative movement trend, thereby causing the buffer connection slider 241 and the buffer connection matching groove 242 to produce a small movement along the axis direction parallel to the propulsion mechanism shell 211. The buffer connection support spring 245 can provide sufficient support thrust to keep the relative position between the buffer connection slider 241 and the buffer connection matching groove 242 stable. The buffer connection shock-absorbing rod 246 can well absorb the displacement movement between the buffer connection slider 241 and the buffer connection matching groove 242 caused by the impact vibration.

[0100] In actual drilling survey, the axial stabilization mechanism 28 is used to keep the position of the axis of the main drill pipe 23 and the axis of the propulsion mechanism shell 211 relatively stable, and the axial stabilization mechanism 28 can buffer and absorb the impact vibration in the radial direction of the main drill pipe 23. The multiple axial stabilization support rods 283 can provide good support for the axial stabilization constraint ring 284, so that the axial stabilization constraint ring 284 and the axial stabilization support ring 281 are always in a coaxial state, avoiding large deviations of the main drill pipe 23 during the drilling process.
