The connecting mechanism also includes a connecting rod horizontally slidably arranged on the column, and the connecting rod is connected to the first magnetic block at one end facing the first connecting groove, and the first magnetic block and the second magnetic block repel each other.

[0010] Furthermore, a connecting block is provided on the top surface of the cylinder, an L-shaped positioning rod is provided on the first magnetic block, and the other end of the positioning rod can abut against the connecting block.

[0014] The second object of the present invention is achieved by the following technical solutions: A prospecting method for a geological prospecting device with good stability and adjustable height, using the above-mentioned geological prospecting device with good stability and adjustable height, includes the following steps: (1) Move in place through the moving wheels, connect the cylinder and the circular sleeve through the connecting mechanism, start the motor, drive the ejecting mechanism to eject the support plate through the cylinder and the circular sleeve, so that the support plate is in full contact with the ground, and then turn off the motor; (2) Separate the cylinder and the circular sleeve through the connecting mechanism, start the motor, drive the lifting mechanism to lift and lower through the cylinder to adjust the geological profiler in place, and then turn off the motor; (3) Start the geological profiler to measure the geological profile and obtain geological profile data.

[0015] The beneficial effects of the present invention are: The geological prospecting device of the present invention with good stability and adjustable height, when in use, moves in place through the moving wheels, connects the cylinder and the circular sleeve through the connecting mechanism, starts the motor, drives the ejecting mechanism to eject the support plate through the cylinder and the circular sleeve, so that the support plate is in full contact with the ground. The contact area between the support plate and the ground is much larger than the contact area between the moving wheels and the ground, which can ensure the stability of the device. Then turn off the motor, separate the cylinder and the circular sleeve through the connecting mechanism, start the motor, drive the lifting mechanism to lift and lower through the cylinder to adjust the geological profiler in place, and can adjust the height of the geological profiler according to different terrain factors, with good adaptability. One motor drives the ejecting mechanism and the lifting mechanism, with low cost. The prospecting method of the geological prospecting device of the present invention with good stability and adjustable height is simple to operate.

[0016] The lead screw of the lifting mechanism rotates with the cylinder, drives the connecting plate to lift and lower. The connecting plate lifts and lowers to drive the geological profiler to lift and lower through the bracket, realizing the height adjustment of the geological profiler.

[0017] The ejector rod, fixed plate, and elastic block of the ejection mechanism rotate with the circular sleeve. Due to the restriction of the baffle, the elastic block is gradually squeezed, and the gas inside it gradually enters the upper end of the circular groove, overcoming the elastic force of the second return spring. The ejector rod gradually extends and acts on the inclined surface of the slider. Since the slider cannot move horizontally, it can only gradually move downward, driving the support plate downward. When the support plate is in full contact with the ground, the ejector rod is just on the top surface of the slider, pushing the pressure plate inward so that the pressure plate fits with the fixed plate, and the pressing block clamps the fixed plate and the compressed elastic block with the baffle post, so that the ejector rod continuously acts on the top surface of the slider, and the support plate is in full contact with the ground, enabling the device to be supported on the ground by the support plate; when the support plate needs to be retracted, pull the baffle and the pressure plate outward to make them away from the fixed plate and the elastic block, and then rotate the circular sleeve.

[0018] After the pressure plate is pushed, the limiting plate in the rectangular groove falls freely to block the pressure plate to prevent the pressure plate from retracting. When the support plate needs to be retracted, first move the limiting plate upward so that it enters the rectangular groove, and then pull the baffle and the pressure plate outward.

[0019] When the cylinder and the circular sleeve need to be connected, align their first connection groove and the second connection groove. The second magnetic block is partially located in the first connection groove and partially located in the second connection groove under the action of the third return spring to achieve connection; when the cylinder and the circular sleeve need to be separated, push the connecting rod inward. Since the first magnetic block and the second magnetic block repel each other, the second magnetic block is pushed into the second connection groove, and the cylinder and the circular sleeve are separated.

[0020] When the positioning rod abuts against the connecting block, the first connection groove is aligned with the second connection groove.

[0021] During the process of the support plate contacting the ground, the elastic sleeve is compressed, and the pressure sensor in the elastic sleeve detects the pressure and transmits it to the controller. When the pressure value exceeds the set value, the controller controls the alarm to sound. Manually push the pressing block in place quickly, and the controller shuts down the motor after 15 s - 20 s to avoid damage due to excessive load on the motor caused by the baffle block.

[0022] Before the support plate moves downward, step on the elastic hollow block of the foot pad. The gas in the elastic hollow block enters the upper end of the connecting column through the connecting pipe, overcoming the elastic force of the elastic rope, and the sliding rod moves downward, overcoming the magnetic force, and the cleaning plate drops. Move the device through the moving wheels. The cleaning plate clears impurities such as sand and gravel on the ground to make the ground flat. After cleaning is completed and the support plate moves downward, the cleaning plate returns to the storage groove, and under the action of the magnetic force, it can be ensured that the cleaning plate does not fall out.

[0023] After the hollow cleaning plate drops, the rectangular block is no longer adsorbed by the magnetic plate and moves downward under the action of the fourth return spring, and the brush extends out of the brush hole to clean the ground. After the cleaning plate returns to the storage groove, the rectangular block is adsorbed by the magnetic plate, and the fourth return spring is compressed, and the brush is retracted into the cleaning plate.

Figure 6As shown in the figure, a first connection groove 21 is horizontally penetrated through the circular sleeve 8. A second connection groove 22 that can be aligned with the first connection groove 21 is provided on the cylinder 7. A second magnetic block 23 is slidably arranged in the second connection groove 22. A third return spring is connected between the second magnetic block 23 and the inner side wall of the second connection groove 22. A connecting rod 25 is horizontally slidably arranged on the upright column 2. A first magnetic block 24 is provided on a section of the connecting rod 25 facing the first connection groove 21. The first magnetic block 24 and the second magnetic block 23 repel each other. A connecting block 27 is provided on the top surface of the cylinder 7. An L-shaped positioning rod 26 is provided on the first magnetic block 24. The other end of the positioning rod 26 can abut against the connecting block 27. As Figure 3 shown, an elastic sleeve 30 is penetrated through the support plate 29. The lower end of the elastic sleeve 30 is exposed outside the support plate 29. A pressure sensor is arranged in the elastic sleeve 30. The pressure sensor is connected to a controller. The controller is connected to the drive circuit of the motor 6 and an alarm. As Figure 7 shown, a storage groove 33 is formed on the bottom surface of the support plate 29. A magnetic plate 35 is provided on the top surface of the storage groove 33. A cleaning plate 34 made of magnetic material is arranged in the storage groove 33. A round rod 32 that slidably penetrates through the top surface of the storage groove 33 is provided on the cleaning plate 34. A connection hole 31 corresponding to the round rod 32 is provided on the bottom surface of the base 1. A hollow connection column 36 with an open bottom is vertically arranged on the support plate 29. A sliding rod 37 is hermetically and slidably arranged up and down in the connection column 36. That is, the connection mode of the sliding rod 37 and the connection column 36 can refer to that of a cylinder. The lower end of the sliding rod 37 is located in the storage groove 33. An elastic rope is connected between the lower end of the sliding rod 37 and the top surface of the storage groove 33. The upper end of the connection column 36 is connected to an elastic hollow block 39 arranged on the side surface of the base 1 through a connection pipe 38. As Figure 8 shown, the cleaning plate 34 is of a hollow structure. Brush holes are provided on the bottom surface of the cleaning plate 34. A rectangular block 40 made of magnetic material is arranged in the cleaning plate 34. A fourth return spring is arranged between the rectangular block 40 and the inner top surface of the cleaning plate 34. Brushes 41 are provided on the bottom surface of the rectangular block 40 corresponding to the brush holes.

[0036] When in use, the device is moved to a suitable position by the moving wheels. Then, kick the elastic hollow block 39 with the foot. The elastic hollow block 39 compresses the gas inside it and enters the upper end of the connecting column 36, pushing the sliding rod 37 downward. The sliding rod 37 pushes the cleaning plate 34, overcoming the magnetic attraction force of the magnetic plate 35 on the cleaning plate 34. The cleaning plate 34 is pushed out. The rectangular block 40 in the cleaning plate 34 is not magnetically attracted by the magnetic plate 35 and moves downward under the action of the fourth return spring. After the rectangular block 40 moves downward, the brush 41 on it passes through the brush hole. Push and pull the device back and forth, and the brush 41 removes impurities such as sand and gravel on the ground. Push the baffle 15 inward so that the free end of the baffle 15 contacts the circular sleeve 8 (before this, the circular sleeve 8 and the cylinder 7 are connected by the second magnet 23). Start the motor 6. The motor 6 drives the cylinder 7 and the circular sleeve 8 to rotate. During the rotation of the circular sleeve 8, the elastic block 11 contacts the baffle 15. Due to the limitation of the baffle 15, the fixing plate 16 and the baffle 15 gradually squeeze the elastic block 11. The gas in the elastic block 11 gradually enters the upper end of the circular groove 9, overcoming the elastic force of the second return spring 12, and gradually pushing out the ejector rod 10. The ejector rod 10 gradually extends and acts on the inclined surface of the slider 28. Since the slider 28 cannot move horizontally, it can only gradually move downward, driving the support plate 29 to move downward. During the downward movement of the support plate 29, the storage groove 33 covers the outside of the cleaning plate 34. Under the magnetic attraction of the magnetic plate 35 on the cleaning plate 34, the cleaning plate 34 fits on the top wall of the storage groove 33. The rectangular block 40 in the cleaning plate 34 moves upward under the magnetic attraction of the magnetic plate 35, overcoming the elastic force of the fourth return spring, and the brush 41 is received into the cleaning plate 34. During the process of the support plate 29 contacting the ground, the elastic sleeve 30 on the support plate 29 is compressed. The pressure sensor in the elastic sleeve 30 real-time detects the pressure in the elastic sleeve 30 and transmits it to the controller. When the pressure value exceeds the set value, that is, when the support plate 29 is in full contact with the ground and the ejector rod 10 just reaches the top surface of the slider 28, the controller controls the alarm to sound. Manually push the pressing plate 17 to make the pressing plate 17 fit with the fixing plate 16. The pressing plate 17 and the baffle 15 clamp the fixing plate 16 and the elastic block 11, so that the ejector rod 10 continuously remains on the top surface of the slider 28, and the support plate 29 is in full contact with the ground, making the device supported on the ground by the support plate 29. After the pressing plate 17 is pushed to fit with the fixing plate 16, the limiting plate 18 in the rectangular groove 19 extends out of the rectangular groove 19 under its own weight and blocks the side of the pressing plate 17 away from the elastic block 11 to limit the pressing plate 17. After the alarm sounds for 15s - 20s, the controller controls the motor 6 to turn off.When the circular sleeve 8 and the cylinder 7 rotate slowly, they push the connecting rod 25 to make the positioning rod 26 press against the connecting block 27. The first magnetic block 24 and the second magnetic block 23 repel each other, overcoming the elastic force of the third return spring. The second magnetic block 23 retracts into the second connecting groove 22, and the cylinder 7 and the circular sleeve 8 are separated. Then, the motor 6 is started. The motor 6 drives the cylinder 7 to rotate, and the cylinder 7 drives the lead screw 3 to rotate. Since the connecting plate 4 cannot rotate, the lead screw 3 drives the connecting plate 4 to move up and down to adjust the geological profiler 5 to a suitable height. Then, the motor 6 is stopped for geological profile measurement. During the stopping process of the motor 6, when the cylinder 7 rotates slowly, it pushes the connecting rod 25 and the positioning rod 26 presses against the connecting block 27 to align the first connecting groove 21 with the second connecting groove 22. Then, the connecting rod 25 is retracted. The first magnetic block 24 has no repulsive force on the second magnetic block 23. Under the action of the third return spring, the second magnetic block 23 is partially located in the first connecting groove 21 and partially located in the second connecting groove 22, connecting the cylinder 7 and the circular sleeve 8. After the geological profile measurement is completed, the limiting plate 18 is pushed into the rectangular groove 19, and the baffle 16 and the pressing plate 17 are pulled back. Under the resilience of the elastic block 11 and the resilience of the second return spring 12, the ejector rod 10 retracts, the slider 28 retracts, and the support plate 29 rises, making the device easy to move.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the present technical solution, and they should all be covered by the scope of the claims of the present invention.
