DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In the embodiment of the present invention, please refer to Figures 1 to 11 A drilling device for geological prospecting, comprising a fixed frame 1, a sampling drill tube 5 and a crushing tooth 6, wherein the crushing tooth 6 is arranged at the bottom of the sampling drill tube 5, the sampling drill tube 5 is located inside the fixed frame 1, a cavity is opened inside the sampling drill tube 5, and a cutting cavity connected to the cavity is opened at the bottom of the sampling drill tube 5, and further comprising: The telescopic member 2 has a top end connected to the top of the fixing frame 1; The sliding plate 3 is connected to the bottom end of the telescopic member 2 and is slidably connected to the inner wall of the fixed frame 1; A driving member 4 is connected to the sliding plate 3, and an output end thereof is detachably connected to the top of the sampling drill tube 5; The cutting and carrying mechanism 7 is connected to the sampling drill tube 5 and is used to cut off the bottom of the sample soil column and carry it. The cutting and carrying mechanism 7 includes: A power assembly 71, one end of which is connected to the top of the sampling drill tube 5; A gear ring 1 72 is connected to the other end of the power assembly 71, and the gear ring 1 72 is disposed in the cavity of the sampling drill tube 5; Gear 1 73 meshes with gear ring 1 72, and the gear 1 73 is provided in a plurality of groups and is arranged circumferentially at equal intervals; The rotating rod 74 passes through the gear 1 73 and is connected thereto; The cutting blade arc 75 is connected to the bottom end of the rotating rod 74, and the cutting blade arc 75 is arranged in the cutting cavity of the sampling drill tube 5; A rotating ring 76 is rotatably connected to the rotating rod 74 and is rotatably connected to the sampling drill tube 5; The sequence limiting component 77 has one end connected to the rotating rod 74 and the other end connected to the sampling drill tube 5 . The sequence limiting component 77 is arranged inside the cavity of the sampling drill tube 5 .

[0027] In the initial state, the cutting bearing blade arc 75 is located in the cutting cavity of the sampling drill tube 5, and several groups of cutting bearing blade arcs 75 form a circle. When drilling and sampling, the driving member 4 drives the sampling drill tube 5 to rotate, and the telescopic member 2 drives the sampling drill tube 5 to move downward, and the crushing teeth 6 drill the ground. When the sampling drill tube 5 penetrates deep into the ground, the sample soil column enters the interior of the sampling drill tube 5. When the sample needs to be taken out, the power component 71 drives the gear ring 1 72 to rotate. In the initial rotation state, the rotation sequence limiting component 77 limits the rotating ring 1 76. At this time, the gear ring 1 72 drives the gear 1 73 to rotate, and the gear 1 73 drives the rotating rod 74 to rotate, and the rotating rod 74 drives the cutting bearing blade arc 75 to rotate, so that several groups of cutting bearing blade arcs 75 extend out and are inserted into the bottom of the sample. When the cutting bearing blade arc 75 After rotating to the specified angle, the rotation sequence limiting component 77 releases the restriction on the rotating ring 1 76, and restricts the gear 1 73. At this time, the gear 1 73 cannot continue to rotate, and the gear ring 1 72 drives the gear 1 73, the rotating rod 74, the cutting bearing blade arc 75 and the rotating ring 1 76 to revolve synchronously. The cutting bearing blade arc 75 cuts the bottom of the sample to separate the sample from the external soil layer. The telescopic member 2 moves in the opposite direction to take out the sampling drill tube 5, and then the power component 71 reverses, driving the gear 1 73 to reverse, and then retracting the cutting bearing blade arc 75 into the cutting chamber. The power component 71 continues to reverse, driving the gear 1 73, the rotating rod 74, the cutting bearing blade arc 75 and the rotating ring 1 76 to revolve synchronously in the opposite direction, returning to the original position, so as to cut next time, and then take out the sample soil layer. The driving member 4 can be a stepping motor, a servo motor, etc., and the telescopic member 2 can be a cylinder, an electric telescopic rod, etc.

[0028] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , the power assembly 71 comprises: The power member 711 is connected to the top of the sampling drill tube 5; Gear 2 712 is connected to the output end of the power member 711 and is rotatably connected to the top of the sampling drill tube 5; The second gear ring 713 meshes with the second gear 712; The second rotating ring 714 is rotatably connected to the outer wall of the sampling drill tube 5 and is connected to the second gear ring 713; The top end of the connecting rod 715 is connected to the rotating ring 2 714 , and the bottom end is connected to the gear ring 1 72 .

[0029] The power piece 711 drives the second gear 712 to rotate, the second gear 712 drives the second gear ring 713 to rotate, the second gear ring 713 drives the connecting rod 715 to rotate, and the second rotating ring 714 ensures the stable rotation of the second gear ring 713. The power piece 711 can be a stepping motor, a servo motor, etc.

[0030] As an embodiment of the present invention, please refer to Figure 3 , Figures 5 to 11 , the sequence limiting component 77 includes: A connecting tube 771 is connected to the top of the rotating rod 74, and a circular groove is formed on the side wall of the connecting tube 771; The bottom end of the telescopic folding rod 772 is connected to the rotating ring 1 76; The movable folding rod 773 is connected to the top of the telescopic folding rod 772, and the movable folding rod 773 is movably engaged with the circular groove; A magnetic fixing component 774, one end of which is connected to the movable folding rod 773, and the other end of which is connected to the inner wall of the connecting tube 771; An elastic member 775, the bottom end of which is connected to a rotating ring 76, and the top end of which is connected to a movable folding rod 773, wherein the elastic force of the elastic member 775 is smaller than the fixing force of the magnetic fixing assembly 774; A lifting and restoring assembly 776, one end of which is connected to the telescopic folding rod 772, and the other end of which is connected to the sampling drill tube 5; The elastic clamping assembly 777 is connected to the movable folding rod 773; The clamping sleeve 778 is connected to the sampling drill tube 5 and is clamped with the elastic clamping assembly 777. The side wall of the clamping sleeve 778 is a bevel structure and gradually decreases from the top to the bottom.

[0031] In the initial state, the movable folding rod 773 is located at the top of the corner of one side of the circular groove, the magnetic fixing component 1 774 fixes the movable folding rod 773, the elastic member 1 775 is in a stretched state, and the elastic force of the elastic member 1 775 is smaller than the magnetic attraction of the magnetic fixing component 1 774, and the elastic clamping component 777 is clamped with the clamping sleeve 778 to limit the rotating ring 1 76; When the sample soil layer is cut, the connecting rod 715 drives the gear ring 72 to rotate. Since the elastic clamping assembly 777 is clamped with the clamping sleeve 778 at this time, the rotating ring 76 cannot rotate. Then: the gear ring 72 drives the gear 73 to rotate, the gear 73 drives the rotating rod 74 to rotate, and the rotating rod 74 drives the cutting bearing blade arc 75 to rotate, so that several groups of cutting bearing blade arcs 75 extend out and are inserted into the bottom of the sample. At the same time, the rotating rod 74 drives the connecting tube 771 to rotate, and the connecting tube 771 drives the magnetic fixing assembly 774 to rotate. When the cutting bearing blade arc 75 rotates to a specified angle, at this time, the movable folding rod 773 is located at the top of the corner on the other side of the circular groove, and the magnetic fixing assembly 774 is separated, releasing the fixation of the movable folding rod 773. Under the reaction force of the elastic member 775, the movable folding rod 773 moves downward in a straight line until it abuts against the bottom of the circular groove on this side. The rod 773 drives the elastic clamping assembly 777 to move downward and disengage from the clamping sleeve 778, thereby releasing the limit of the rotating ring 1 76. At this time, the gear ring 1 72 continues to rotate. Since the movable folding rod 773 abuts against the side wall of the circular groove of the connecting tube 771, the connecting tube 771 cannot continue to rotate, thereby limiting the rotation of the gear 1 73. The gear ring 1 72 drives the gear 1 73, the rotating rod 74, the cutting bearing blade arc 75 and the rotating ring 1 76 to revolve synchronously. The cutting bearing blade arc 75 cuts the bottom of the sample to separate the sample soil layer from the external soil layer. At the same time, the cutting bearing blade arc 75 also plays a supporting role for the sample soil layer to prevent the sample soil layer from falling. After the cutting bearing blade arc 75 revolves at a specified angle, the power piece 711 stops working. At this time, the lifting and restoring assembly 776 limits and fixes the telescopic folding rod 772, and then limits and fixes the rotating ring 1 76. After the sampling drill tube 5 moves to the ground, when the sample soil layer needs to be taken out, the power piece 711 rotates in the opposite direction, driving the gear ring 72 to rotate in the opposite direction. Due to the limiting and fixing effect of the lifting and restoring assembly 776 on the rotating ring 76, the rotating ring 76 cannot revolve. At this time, the gear ring 72 drives the gear 73 to rotate in the opposite direction, thereby driving the cutting bearing blade arc 75 to rotate and retract into the cutting cavity. The gear 73 drives the connecting tube 771 to rotate in the opposite direction. When the cutting bearing blade arc 75 is retracted into the cutting cavity, the movable folding rod 773 is located at the bottom of the original side wall. Since the movable folding rod 773 abuts against the side wall, the connecting tube 771 is restricted, so that the connecting tube 771 and the gear 73 cannot continue to rotate. At this time, the gear ring 72 drives the gear 73, the rotating rod 74, the cutting bearing blade arc 75 and the rotating ring 76 to revolve in the opposite direction synchronously. During the reverse revolution, the lifting and restoring assembly 776 releases the restriction on the gear ring 72. At the same time, the lifting and restoring assembly 776 releases the restriction on the gear ring 72. When the movable folding rod 773 is moved upward, the movable folding rod 773 is moved upward to the top of the lifting and restoring assembly 776, and the movable folding rod 773 has not yet moved to its original height, and the elastic clamping assembly 777 has not been clamped with the clamping sleeve 778. However, since the movable folding rod 773 has moved upward a certain distance, the magnetic attraction between the magnetic fixing assembly 774 increases. Under the action of the magnetic attraction, the movable folding rod 773 overcomes the action of the elastic member 775 and moves upward to the top of the circular groove, that is, at this time, the movable folding rod 773 returns to its original height, the rotating ring 1 76 continues to rotate in the opposite direction, so that the elastic clamping assembly 777 abuts against the clamping sleeve 778, causing the elastic clamping assembly 777 to move downward. When the rotating ring 1 76 rotates to the original position, at this time, the elastic clamping assembly 777 and the clamping sleeve 778 are on the same vertical line, the elastic clamping assembly 777 moves upward until it is clamped with the clamping sleeve 778, and the entire cutting support mechanism 7 returns to its original position.

[0032] The elastic member 775 can be a spring, a spring sheet, etc.

[0033] As an embodiment of the present invention, please refer to Figures 9 to 11 , the magnetic solid component 774 includes: A magnetic block 7741 is connected to the inner wall of the connecting tube 771; The second magnetic block 7742 is connected to the movable folding rod 773, and the magnetic properties of the second magnetic block 7742 and the first magnetic block 7741 are opposite.

[0034] The magnetic block 1 7741 and the magnetic block 2 7742 are magnetically attracted together to fix the movable folding rod 773, and the magnetic attraction force between the magnetic block 2 7742 and the magnetic block 1 7741 is greater than the pulling force of the elastic member 1 775; When the connecting tube 771 rotates, the magnetic block 1 7741 is driven to rotate, so that the magnetic block 1 7741 is separated from the magnetic block 2 7742, and the magnetic attraction between the two disappears, so that the movable folding rod 773 can move downward under the reaction force of the elastic member 1 775.

[0035] As an embodiment of the present invention, please refer to Figures 5 to 10 , the lifting and restoring assembly 776 comprises: The second magnetic fixing component 7761 has one end connected to the telescopic folding rod 772 and the other end connected to the sampling drill tube 5; The abutment rod 7762 is connected to the movable folding rod 773; The oblique arc block 7763 is connected to the sampling drill tube 5. The oblique arc block 7763 is a trapezoidal structure, and the top length is smaller than the bottom length. The top horizontal section of the oblique arc block 7763 is located at the bottom of the abutment rod 7762. The second magnetic solid component 7761 includes: The third magnetic block 77611 is connected with the telescopic folding rod 772; The fourth magnetic block 77612 is connected to the sampling drill tube 5, and the magnetic properties of the fourth magnetic block 77612 and the third magnetic block 77611 are opposite; The elastic clamping assembly 777 includes: The sliding clamping rod 7771 is slidably connected to the top of the movable folding rod 773, and the top of the sliding clamping rod 7771 is close to the clamping sleeve 778 on one side thereof and has a bevel structure; The second elastic member 7772 has a bottom end connected to the movable folding rod 773 and a top end connected to the bottom end of the sliding clamping rod 7771.

[0036] In the initial state, the fourth magnetic block 77612 and the third magnetic block 77611 are in a separated state, the bottom of the movable folding rod 773 is located above the top horizontal section of the oblique arc block 7763, and the sliding clamping rod 7771 is clamped with the clamping sleeve 778; When the movable folding rod 773 moves downward under the reaction of the elastic member 775, when the movable folding rod 773 moves to the bottom and abuts against the horizontal section of the oblique arc block 7763, the sliding clamping rod 7771 is separated from the clamping sleeve 778; When the rotating ring 1 76 drives the telescopic folding rod 772 to revolve, the telescopic folding rod 772 drives the magnetic block 3 77611 to revolve. When the magnetic block 3 77611 rotates to contact the magnetic block 4 77612, the power piece 711 stops working. At this time, the magnetic block 3 77611 and the magnetic block 4 77612 are magnetically attracted together to limit the rotating ring 1 76. When the power piece 711 rotates in the opposite direction, due to the magnetic attraction between the third magnet block 77611 and the fourth magnet block 77612, the rotating ring 1 76 cannot rotate. When the cutting bearing blade arc 75 is retracted into the cutting chamber, due to the limiting of the movable folding rod 773, the rotating ring 1 76 revolves in the opposite direction. At this time, the third magnet block 77611 is separated from the fourth magnet block 77612, and the abutment rod 7762 moves along the hypotenuse of the oblique arc block 7763 during the rotation process, so that the movable folding rod 773 moves upward. When the movable folding rod 773 moves to the horizontal section at the top of the oblique arc block 7763, the distance between the first magnet block 7741 and the second magnet block 7742 is reduced, and the magnetic attraction is enhanced. When the sliding clamp rod 7771 rotates and contacts with the clamping sleeve 778, the sliding clamp rod 7771 rotates and contacts with the clamping sleeve 778, because the side of the sliding clamp rod 7771 close to the clamping sleeve 778 is a bevel structure, the sliding clamp rod 7771 rotates and moves downward to squeeze the elastic member 2 7772. When the rotating ring 1 76 rotates to the original position, the sliding clamp rod 7771 and the clamping sleeve 778 are on the same vertical line. Under the reaction force of the elastic member 2 7772, the sliding clamp rod 7771 moves upward to connect with the clamping sleeve 778, and the entire cutting support mechanism 7 returns to its original position.

[0037] The elastic member 7772 may be a spring, a spring sheet, or the like.

[0038] As an embodiment of the present invention, please refer to Figure 1 , also includes: The limiting ring 8 is connected to the fixing frame 1, and the sampling drill tube 5 passes through the limiting ring 8 and is movably connected thereto.

[0039] The sampling drill tube 5 is limited by the provided limiting ring 8 to ensure stable movement.

[0040] The working principle of the present invention is as follows: in the initial state, the cutting bearing blade arc 75 is located in the cutting cavity of the sampling drill tube 5, the movable folding rod 773 is located at the top of the corner of one side of the circular groove, the elastic member 1 775 is in a stretched state, and the elastic force of the elastic member 1 775 is smaller than the magnetic attraction between the magnetic block 1 7741 and the magnetic block 2 7742, the magnetic block 4 77612 and the magnetic block 3 77611 are in a separated state, the bottom of the movable folding rod 773 is located above the horizontal section of the top of the oblique arc block 7763, and the sliding clamping rod 7771 is clamped with the clamping sleeve 778; When drilling and sampling, the driving member 4 drives the sampling drill tube 5 to rotate, the telescopic member 2 drives the sampling drill tube 5 to move downward, and the crushing teeth 6 drill the ground. When the sampling drill tube 5 penetrates deep into the ground, the sample soil column enters the interior of the sampling drill tube 5. When the sample needs to be taken out, the power member 711 drives the gear 2 712 to rotate, the gear 2 712 drives the gear ring 2 713 to rotate, the gear ring 2 713 drives the connecting rod 715 to rotate, and the connecting rod 715 drives the gear ring 1 72 to rotate. At this time, the sliding clamping rod 7771 is engaged with the clamping sleeve 778, and the rotating ring If the gear ring 72 drives the gear 73 to rotate, the gear 73 drives the rotating rod 74 to rotate, the rotating rod 74 drives the cutting blade arc 75 to rotate, so that a plurality of cutting blade arcs 75 extend out and are inserted into the bottom of the sample. At the same time, the rotating rod 74 drives the connecting tube 771 to rotate. When the cutting blade arc 75 rotates to a specified angle, the movable folding rod 773 is located at the top of the corner on the other side of the circular groove, and the connecting tube 771 drives the magnetic block 1 7741 to rotate, so that the magnetic block 1 7741 and the magnetic block 2 7742 is disengaged, and the magnetic attraction between the two disappears, so that the movable folding rod 773 moves downward under the reaction force of the elastic member 1 775 until it abuts against the bottom of the circular groove, and the movable folding rod 773 drives the sliding clamping rod 7771 to move downward and disengage from the clamping sleeve 778, thereby releasing the limit on the rotating ring 1 76. At this time, the gear ring 1 72 continues to rotate. Since the movable folding rod 773 abuts against the side wall of the circular groove of the connecting tube 771, the connecting tube 771 cannot continue to rotate, thereby limiting the rotation of the gear 1 73, and the gear ring 1 72 drives the gear 1 774 to rotate. 3. The rotating rod 74, the cutting bearing blade arc 75 and the rotating ring 1 76 revolve synchronously, and the cutting bearing blade arc 75 cuts the bottom of the sample to separate the sample soil layer from the external soil layer. When the rotating ring 1 76 drives the telescopic folding rod 772 to revolve, the telescopic folding rod 772 drives the magnetic block 3 77611 to revolve. When the magnetic block 3 77611 rotates to contact the magnetic block 4 77612, the power piece 711 stops working. At this time, the magnetic block 3 77611 and the magnetic block 4 77612 are magnetically attracted together to limit the rotating ring 1 76. After the sampling drill tube 5 moves to the ground, when the sample soil layer needs to be taken out, the power piece 711 rotates in the opposite direction, driving the gear ring 1 72 to revolve in the opposite direction. At this time, due to the magnetic attraction between the magnet block 3 77611 and the magnet block 4 77612, the rotating ring 1 76 cannot rotate. At this time, the gear ring 1 72 drives the gear 1 73 to rotate in the opposite direction, thereby driving the cutting blade arc 75 to rotate and retract into the cutting chamber. The gear 1 73 drives the connecting tube 771 to rotate in the opposite direction. When the cutting blade arc 75 is retracted, the connecting tube 771 rotates in the opposite direction. After the cutting cavity, at this time, the movable folding rod 773 is located at the bottom of the original side wall. Since the movable folding rod 773 abuts against the side wall, the connecting cylinder 771 is restricted, so that the connecting cylinder 771 and the gear 1 73 cannot continue to rotate. At this time, the gear ring 1 72 drives the gear 1 73, the rotating rod 74, the cutting blade arc 75 and the rotating ring 1 76 to rotate synchronously in the opposite direction. At this time, the magnetic block 3 77611 is separated from the magnetic block 4 77612, and the abutting rod 7762 rotates along the oblique arc block 77 The beveled edge movement of 63 causes the movable folding rod 773 to move upward. When the movable folding rod 773 moves to the top horizontal section of the beveled arc block 7763, the distance between the magnetic block 1 7741 and the magnetic block 2 7742 is reduced, and the magnetic attraction is enhanced. Driven by the magnetic attraction, the movable folding rod 773 moves upward to the original height. At this time, the sliding clamping rod 7771 is higher than the clamping sleeve 778, and the rotating ring 1 76 continues to revolve in the opposite direction. When the sliding clamping rod 7771 rotates and abuts against the clamping sleeve 778, due to the sliding The side of the clamping rod 7771 close to the clamping sleeve 778 is a bevel structure, so that the sliding clamping rod 7771 rotates and moves downward to squeeze the elastic member 2 7772. When the rotating ring 1 76 rotates to the original position, the sliding clamping rod 7771 and the clamping sleeve 778 are on the same vertical line. Under the reaction force of the elastic member 2 7772, the sliding clamping rod 7771 moves upward to engage with the clamping sleeve 778, and the entire cutting bearing mechanism 7 returns to its original position, thereby facilitating the removal of the sample soil layer.
