[0028] The beneficial effects of the present invention are:

[0029] In the present invention, a geological survey device is described, which moves the survey device to a position where geological survey is required by pushing the handrail frame to make the universal wheel roll on the ground, and then the brake pad is rotated to lock the universal wheel, and the driving motor and the servo motor are started, the driving motor drives the worm, the driving shaft, the driving gear and the rotating plate to rotate synchronously, the driving gear drives the hollow shaft, the drill bit and the spiral auger to rotate by meshing with the driven gear, the rotating plate drives the sampling tube to rotate reciprocatingly by cooperating with the round rod, the sliding frame and the connecting frame, and at the same time, the two servo motors operate synchronously to drive the two screws to rotate synchronously, and the two screws drive the screws through the threaded transmission with the side plates and under the guidance of the vertical plates. The two side plates move downward synchronously, and the two side plates jointly drive the mounting plate to move downward. The mounting plate drives the collection frame to move downward through the connecting spring, so that the sampling tube and the hollow shaft rotate and move downward synchronously, so that the sampling tube is inserted into the soil. The rotation of the drill bit can break up the soil and crush the stone. The first conical rod and the second conical rod are driven to rotate by the sampling tube to further break up the soil and further crush the stone. The spiral auger transports the soil upward while rotating, so that the soil enters the collection frame. The soil slides to the right under the action of gravity and falls into the collection frame, thereby realizing automatic sampling of the soil to facilitate geological survey;

[0030] In the present invention, a geological survey device is described, when the sampling tube and the drill bit move downward, they will be subject to resistance from soil and stone, thereby preventing the collection frame from moving downward, shortening the distance between the collection frame and the mounting plate, and increasing the compression amount of the connecting spring. At the same time, the collection frame drives the adjustment plate to move leftward through the linkage rod, and the adjustment plate drives the first resistor bar and the second resistor bar to move leftward, so that the overlap degree between the first resistor bar and the first resistor tube is increased, thereby increasing the conductive cross-sectional area and shortening the conductive path, thereby reducing the resistance value of the first adjustable resistor. Since the first adjustable resistor is connected in series with the drive motor, the current passing through the drive motor is increased, and the working power of the drive motor is increased, thereby increasing the rotation speed of the drive shaft, the drill bit and the sampling tube to improve the crushing effect of the stone. At the same time, the second resistor bar moves to the left, reducing the overlap area between it and the second resistor tube, thereby increasing the resistance value of the second adjustable resistor. Since the second adjustable resistor is connected in series with the servo motor, the power of the servo motor is reduced, thereby reducing the rotation speed of the screw rod, and reducing the speed at which the drill bit and the sampling tube move downward, thereby avoiding excessive load on the drill bit and the sampling tube.

[0031] In the present invention, a geological survey device is described, which drives the second conductive sheet to move horizontally synchronously through the adjustment plate. When the second conductive sheet contacts the first conductive sheet, the electric control valve is energized to open. At the same time, the worm drives the worm wheel to rotate through the meshing with the worm wheel. The worm wheel drives the sealing plate to reciprocate left and right through the cross bar. When the through hole on the sealing plate is connected with the two connecting holes, the compressed air in the compressed gas storage tank enters the drill bit along the connecting pipe, the electric control valve, the connecting hole and the hollow shaft, and pushes the piston plate to move downward. The piston plate drives the conical frame, the disc and the crushing rod to move downward, so that the crushing rod The cone frame quickly extends out from the drill bit to crush the stone. At the same time, the cone frame drives multiple tooth plates to move away from each other through the cooperation of the limit bar and the linkage plate, so that the tooth plate quickly extends out from the drill bit to further crush the stone. When the sealing plate moves to the right to close the upper connecting hole and unblock the lower connecting hole, the piston plate is reset upward under the action of the compression spring, and the air in the drill bit is discharged into the installation box through the lower connecting hole, thereby driving the piston plate to reciprocate up and down under the cooperation of the sealing plate and the compressed gas storage tank, and making the crushing rod and the tooth plate move back and forth repeatedly, so as to achieve continuous impact on the stone and ensure the stone crushing effect;

[0032] In the present invention, in the geological survey device, when the adjustment plate moves to the left to contact the control button, the servo motor is controlled to stop working, thereby stopping the feeding of the sampling tube and the drill bit to avoid excessive resistance and damage to the device;

[0033] In the present invention, the geological survey device can achieve stone crushing while achieving soil sampling through the electric lifting mechanism and sampling mechanism, and can automatically adjust the drilling speed and feeding speed according to the feeding resistance. When the feeding resistance reaches a certain level, it cooperates with the compressed gas storage tank to enhance the stone crushing effect and ensure the sampling efficiency.

[0071] In the present embodiment, when in use, the universal wheel 101 is made to roll on the ground by pushing the handrail frame 12, thereby moving the surveying device to the position where geological survey is required, and then the brake pad is rotated to lock the universal wheel 101, and the drive motor 6 and the servo motor 202 are started, and the drive motor 6 drives the worm 601, the drive shaft 603, the driving gear 604 and the rotating plate 607 to rotate synchronously, and the driving gear 604 drives the hollow shaft 8, the drill bit 9 and the spiral auger 801 to rotate by meshing with the driven gear 605, and the rotating plate 607 drives the sampling tube 7 to reciprocate by cooperating with the round rod 608, the sliding frame 609 and the connecting frame 610. At the same time, the two servo motors 202 operate synchronously, driving the two screw rods 203 to rotate synchronously, and the two screw rods 203 are connected to the side plate 2 by the thread transmission The two side plates 2 move downward synchronously under the guidance of the vertical plate 201, and the two side plates 2 jointly drive the mounting plate 3 to move downward. The mounting plate 3 drives the collection frame 4 to move downward through the connecting spring 308, so that the sampling tube 7 and the hollow shaft 8 rotate and move downward synchronously, so that the sampling tube 7 is inserted into the soil. The rotation of the drill bit 9 can break up the soil and crush the stones. The first conical rod 701 and the second conical rod 702 are driven to rotate by the sampling tube 7 to further break up the soil and further crush the stones. The spiral auger 801 transports the soil upward while rotating, so that the soil enters the collection frame 4. The soil slides to the right under the action of gravity and falls into the collection frame 10, thereby realizing automatic sampling of the soil to facilitate geological surveys.

[0072] When the sampling tube 7 and the drill bit 9 move downward, they will encounter resistance from the soil and stones, thereby preventing the collection frame 4 from moving downward, shortening the distance between the collection frame 4 and the mounting plate 3, and increasing the compression of the connecting spring 308. At the same time, the collection frame 4 drives the adjustment plate 304 to move leftward through the linkage rod 305, and the adjustment plate 304 drives the first resistor bar 313 and the second resistor bar 314 to move leftward, thereby increasing the overlap between the first resistor bar 313 and the first resistor tube 311, thereby increasing the conductive cross-sectional area and shortening the conductive path, thereby reducing the resistance value of the first adjustable resistor. The second adjustable resistor 314 is connected in series with the servo motor 202, so that the power of the servo motor 202 is reduced, and the speed of the drill bit 9 and the sampling tube 7 moving downward is reduced, so as to avoid excessive load on the drill bit 9 and the sampling tube 7;

[0073] The second conductive sheet 310 is driven to move horizontally synchronously through the adjusting plate 304. When the second conductive sheet 310 contacts the first conductive sheet 303, the electric control valve 17 is powered on and opened. At the same time, the worm 601 drives the worm wheel 602 to rotate by meshing with the worm wheel 602. The worm wheel 602 drives the sealing plate 502 to reciprocate left and right through the cross bar 503. When the through hole 5021 on the sealing plate 502 is connected with the two connecting holes, the compressed air in the compressed gas storage tank 13 enters the drill bit 9 along the connecting pipe 14, the electric control valve 17, the connecting hole and the hollow shaft 8, and pushes the piston plate 901 to move downward. The piston plate 901 drives the conical frame 902, the disc 903 and the crushing rod 905 to move downward, so that the crushing rod 905 is quickly extended from the drill bit 9 to crush the stone. At the same time, the conical frame 902 passes through the limiting The cooperation of the position strip and the linkage plate 906 drives the multiple tooth plates 907 to move away from each other, so that the tooth plates 907 are quickly extended from the drill bit 9 to further crush the stone. When the sealing plate 502 moves to the right to close the upper connecting hole and unblock the lower connecting hole, the piston plate 901 is reset upward under the action of the compression spring 904, and the air in the drill bit 9 is discharged into the installation box 5 through the lower connecting hole, thereby driving the piston plate 901 to reciprocate up and down under the cooperation of the sealing plate 502 and the compressed gas storage tank 13, and making the crushing rod 905 and the tooth plate 907 move back and forth repeatedly, realizing continuous impact on the stone, ensuring the stone crushing effect, and the air can take away the heat when circulating in the hollow shaft 8 to avoid its continuous heating, and the air discharged into the installation box 5 is blown to the drive motor 6 under the action of the guiding square tube 16 to accelerate its heat dissipation;
