Description

Technical Field

[0001] The present invention relates to the technical field of land detection, and in particular to a land pH detection device for landscaping. Background Art

[0002] The soil pH detection device detects and collects soil pH information by contacting the detector with the soil, and applies corresponding fertilizer to the soil based on the collected pH information to change the soil quality, thereby ensuring that the roots and stems of the plants are in a suitable growth environment. When detecting the pH of the soil, the existing detection device needs to directly insert the detector into the soil, but the situation in the soil cannot be determined. There may be hard stones and other debris. Directly inserting the detector into the soil will cause damage to the detector. The roots and stems of plants in gardens are generally deep, and the detection depth needs to be adjusted downward accordingly during measurement. During use, the probability of damage to the detector will increase, resulting in inaccurate measured data. Summary of the Invention

Detailed implementation manners

[0033] The present invention will be further described below with reference to the embodiments shown in the drawings.

[0034] Example 1: A soil pH detection device for landscaping, such as Figure 1-Figure 4 As shown, the three circumferentially distributed support legs 11 are commonly fixed to the upper side surfaces of the three circumferentially distributed support legs 11 with a fixed plate 12. The left portion of the lower side surface of the fixed plate 12 is fixed to a first motor 13. The output shaft of the first motor 13 is provided with a sliding sleeve 14. The lower portion of the sliding sleeve 14 is fixed to a first gear 15. The middle portion of the fixed plate 12 is rotatably connected to a first rotating sleeve 16. The lower side of the first rotating sleeve 1 is fixed to a threaded sleeve 17. The lower side of the threaded sleeve 17 is fixed to a second gear 18. The second gear 18 is engaged with the first gear 15 for transmission, and is used to drive the threaded rod 19 to move downward. The threaded sleeve 17 is internally threaded and connected to a threaded rod 19. Rod 19, a telescopic rod is fixedly connected between the upper end of the threaded rod 19 and the left part of the upper side of the fixed plate 12. The telescopic rod is used to prevent the threaded rod 19 from rotating when the threaded sleeve 17 drives the threaded rod 19 to rotate, so that the threaded rod 19 cannot move downward. The lower end of the threaded rod 19 is fixedly connected to the second motor 110, and the output shaft of the second motor 110 is fixedly connected to the sleeve 111. The upper part of the inner side of the sleeve 111 is slidably connected to the piston rod 112, and the lower end of the piston rod 112 is fixedly connected to the fixed rod 113. The outer side of the fixed rod 113 is provided with evenly distributed detectors for detecting the pH value of the soil. The lower end of the fixed rod 113 The end is fixed with a probe 114, the outer side of the probe 114 is slidably connected to the inner side of the support leg 11, and the initial position of the probe 114 is located in the sleeve 111, which is used to prevent the soil at a shallow position from entering the top of the probe 114 and contacting the detector during the downward movement of the probe 114, resulting in inaccurate data collected during subsequent measurements. The probe 114 is conical, and the diameter of the lower part of the probe 114 is smaller than the diameter of its upper part, which is used to reduce the resistance encountered by the probe 114 when it moves downward. The diameter of the fixing rod 113 is smaller than the diameter of the upper side of the probe 114, and the lower end of the threaded rod 19 is fixed with a first push rod 1 15. A liquid storage shell 116 is fixedly connected to the lower side surface of the second motor 110, and a ring plate slidably connected to the liquid storage shell 116 is fixedly connected to the telescopic end of the first push rod 115. The ring plate is located in the liquid storage shell 116 and is used to squeeze the hydraulic oil in the liquid storage shell 116. The liquid storage shell 116 is connected to the sleeve 111 through the output shaft on the second motor 110. A curved through hole is provided at the lower end of the output shaft of the second motor 110, which is used to send the hydraulic oil in the liquid storage shell 116 into the sleeve 111 when the ring plate moves downward. An isolation mechanism is provided on the sleeve 111, and the isolation mechanism is used to prevent the probe 114 from contacting the soil layer when it descends.

[0035] like Figure 5 and Figure 6As shown in the figure, the isolation mechanism includes an annular plate 21. The annular plate 21 is slidably connected to the lower part inside the sleeve 111. A transmission plate 22 is splined to the lower part inside the sleeve 111. The transmission plate 22 is located above the annular plate 21. The upper side surface of the annular plate 21 and the lower side surface of the transmission plate 22 are both provided with circumferentially distributed splines. The splines on the annular plate 21 and the splines on the transmission plate 22 are engaged to drive the annular plate 21 to rotate. Four arc-shaped plates 23 are circumferentially distributed and fixedly connected to the lower side surface of the annular plate 21. The lower side surfaces of the four circumferentially distributed arc-shaped plates 23 are commonly fixedly connected to a drill bit 24. A limiting rod 25 is slidably connected to the lower part of the right side surface inside the sleeve 111. The limiting rod 25 is in limiting cooperation with the annular plate 21 to prevent the annular plate 21 from moving downward and separating from the transmission plate 22 after the splines on the annular plate 21 and the splines on the transmission plate 22 are engaged. A spring is arranged between the limiting rod 25 and the sleeve 111. The spring is used to push the limiting rod 25 to reset. An aggregation mechanism is arranged on the drill bit 24. The aggregation mechanism is used to push the soil to move.

[0036] As Figure 7 and Figure 8 shown in the figure, the aggregation mechanism includes a hydraulic pipe 31. The hydraulic pipe 31 is fixedly connected to the middle part of the upper side surface of the drill bit 24. The telescopic end of the hydraulic pipe 31 is fixedly connected to a pressing plate 32. The pressing plate 32 is in pressing cooperation with the probe 114 to press the pressing plate 32 downward, so as to increase the pressure of the hydraulic oil in the hydraulic pipe 31. Four lifting pipes 33 are circumferentially distributed and fixedly connected to the upper side surface of the drill bit 24. The positions of the lifting pipes 33 correspond to the adjacent arc-shaped plates 23. The lower ends of the four circumferentially distributed lifting pipes 33 are all communicated with the lower end of the hydraulic pipe 31 to drive the telescopic ends of the lifting pipes 33 to move upward. The diameter of the hydraulic pipe 31 is larger than the diameter of the lifting pipe 33. When the pressing plate 32 is pressed, the hydraulic oil in the hydraulic pipe 31 can simultaneously push the telescopic ends of the four lifting pipes 33 to move upward. The telescopic ends of the four circumferentially distributed lifting pipes 33 are all hinged to the lower side surface of the adjacent push plate 34. The upper side surface of the push plate 34 is hinged to the middle part inside the adjacent arc-shaped plate 23. When the telescopic end of the lifting pipe 33 moves upward, it is used to push the adjacent push plate 34 to move inward and push the nearby soil to move to the middle and gather around the fixing rod 113, so that the detector on the fixing rod 113 can contact sufficient soil.

[0037] When it is necessary to detect the acidity and alkalinity of the soil in the garden, the staff needs to first determine the detection position. After determining the detection position, the staff adjusts the position of the drill bit 24 by moving the fixing plate 12 so that the drill bit 24 is located above the detection position. At this time, the staff stops moving the fixing plate 12.

[0038] After the drill bit 24 is located above the detection position, the operator starts the first motor 13. The output shaft of the first motor 13 drives the sliding sleeve 14 to rotate. The sliding sleeve 14 drives the first gear 15 to rotate. The first gear 15 drives the second gear 18 to rotate. The second gear 18 drives the first rotating sleeve 16 and the threaded sleeve 17 to rotate. The rotation of the threaded sleeve 17 drives the threaded rod 19 to move downward through the thread. The downward movement of the threaded rod 19 compresses the adjacent telescopic rods and drives the second motor 110 and the first push rod 115 to move downward. The output shaft of the second motor 110 drives the sleeve 111 and the liquid storage shell 116 to move downward. The telescopic end of the first push rod 115 drives the annular plate to move downward. The sleeve 111 drives the piston rod 112 to move downward. The piston rod 112 drives the fixed rod 113 and the probe 114 to move downward.

[0039] During the downward movement of the sleeve 111, the sleeve 111 drives the transmission plate 22 and the limiting rod 25 to move downward. At this time, the annular plate 21 is located below the limiting rod 25, and the splines on the annular plate 21 do not mesh with the splines on the transmission plate 22. Under the action of gravity, the annular plate 21 drives the drill bit 24 to move downward through the arc-shaped plate 23. The movement of the drill bit 24 drives the hydraulic pipe 31 and the lifting pipe 33 to move downward. The arc-shaped plate 23 drives the adjacent push plate 34 to move downward.

[0040] During the downward movement of the drill bit 24, when the drill bit 24 contacts the ground, the drill bit 24, the arc-shaped plate 23, and the annular plate 21 all stop moving downward. At this time, as the sleeve 111 moves downward, the sleeve 111 drives the transmission plate 22 to move downward, and the annular plate 21 moves upward relative to the sleeve 111. During this process, when the limiting rod 25 contacts the annular plate 21, the upper side of the annular plate 21 presses against the limiting rod 25 and compresses the adjacent spring. The limiting rod 25 continues to move downward with the sleeve 111. When the limiting rod 25 moves to the lower side of the annular plate 21, the limiting rod 25 pops out under the push of the adjacent spring to limit the annular plate 21.

[0041] During the upward movement of the annular plate 21 relative to the transmission plate 22, the splines on the annular plate 21 gradually mesh with the splines on the transmission plate 22. When the annular plate 21 meshes with the transmission plate 22, the operator starts the second motor 110. The output shaft of the second motor 110 drives the sleeve 111 to rotate. The sleeve 111 drives the transmission plate 22 to rotate. The transmission plate 22 drives the annular plate 21 to rotate. The annular plate 21 drives the drill bit 24 to rotate through the arc-shaped plate 23. The rotation of the drill bit 24 breaks and discharges the soil.

[0042] As the drill bit 24 moves downward, after the sleeve 111 moves to the required detection depth, the staff turns off the first motor 13 and the second motor 110. At this time, neither the sleeve 111 nor the drill bit 24 rotates or moves downward anymore. Subsequently, the staff activates the first push rod 115. The telescopic end of the first push rod 115 pushes the annular plate downward to squeeze the hydraulic oil in the liquid storage shell 116. The hydraulic oil in the liquid storage shell 116 enters the sleeve 111 through the holes on the output shaft of the second motor 110. The pressure inside the sleeve 111 increases, pushing the piston rod 112 downward. The piston rod 112 pushes the fixed rod 113 downward, and the fixed rod 113 drives the probe 114 downward. When the probe 114 moves downward, it squeezes the soil on the upper side of the drill bit 24 to both sides through the inclined surface on the probe 114, creating space to facilitate the fixed rod 113 to drive the detector downward.

[0043] During the process of the above-mentioned probe 114 moving downward, when the lower side of the probe 114 contacts the upper side of the extrusion plate 32, the telescopic end of the first push rod 115 continues to push the annular plate downward, and the piston rod 112 continues to push the probe 114 downward. The probe 114 squeezes the extrusion plate 32 downward, and the extrusion plate 32 moves downward to make the telescopic end of the hydraulic pipe 31 move downward and squeeze the hydraulic oil in the hydraulic pipe 31. The hydraulic oil in the hydraulic pipe 31 simultaneously enters the four lifting pipes 33, causing the telescopic ends of the four lifting pipes 33 to rise simultaneously. After the telescopic ends of the lifting pipes 33 rise, they push the adjacent push plates 34 upward through the hinges. Since the upper ends of the adjacent hinges on the upper side of the push plate 34 are fixed, at this time, when the push plate 34 moves upward, it will also move toward the middle. When the push plate 34 moves toward the middle, it pushes the soil inside it toward the middle, gathering the soil near the fixed rod 113, causing a large amount of soil to gather near the detector, avoiding inaccurate data measurement by the detector due to insufficient soil near the detector. When the extrusion plate 32 can no longer move downward, at this time, the staff turns off the first push rod 115, and the staff collects the data measured by the detector.

[0044] After detecting the soil pH value as described above, the staff activates the first motor 13. The output shaft of the first motor 13 rotates in reverse to repeat the above process to drive the threaded sleeve 17 to rotate in the reverse direction. The reverse rotation of the threaded sleeve 17 causes the threaded rod 19 to rise. The rising of the threaded rod 19 drives the second motor 110 and the first push rod 115 to move, driving the sleeve 111 and the liquid storage shell 116 upward. The upward movement of the sleeve 111 repeats the above reverse process to drive the probe 114, the transmission plate 22, and the drill bit upward. At this time, the limiting rod 25 limits the annular plate 21, and the limiting rod 25 drives the annular plate 21 upward. The annular plate 21 drives the drill bit 24 upward. During this process, the splines on the annular plate 21 mesh with the splines on the transmission plate 22.

[0045] After the drill bit 24 leaves the hole and is at a certain distance from the ground, the staff turns off the first motor 13. At this time, the sleeve 111 stops moving upward. The staff presses down on the upper side of the drill bit 24. The drill bit 24 drives the annular plate 21 downward through the arc plate 23. When the annular plate 21 moves downward, it squeezes the limiting rod 25 and compresses the adjacent spring, and gradually separates from the transmission plate 22. After the annular plate 21 moves below the limiting rod 25, the limiting rod 25 resets under the push of the adjacent spring.

[0046] During the downward movement of the drill bit 24 described above, the drill bit 24 drives the hydraulic pipe 31 downward. The hydraulic pipe 31 drives the extrusion plate 32 downward, causing the extrusion plate 32 to gradually separate from the probe 114. At this time, the telescopic end of the hydraulic pipe 31 gradually moves upward to reset. The telescopic end of the hydraulic pipe 31 gradually moves upward to extract the hydraulic oil in the four lifting pipes 33 inside, causing the telescopic ends of the four lifting pipes 33 to gradually move downward to reset. The telescopic end of the lifting pipe 33 moves downward to drive the adjacent push plate 34 to move downward to reset through the hinge, leaving space for the cleaning detector.

[0047] After the above-mentioned annular plate 21 separates from the transmission plate 22, the staff uses a cleaning tool to clean the soil adhered to the fixed rod 113 and the detector, avoiding the soil adhered to the detector, which may cause the detector to be corroded and its service life to be reduced.

[0048] When the staff is cleaning, the staff adjusts the positions of the four arc plates 23 by rotating the drill bit 24 to avoid the arc plates 23 blocking the fixed rod 113 and hindering the staff from cleaning the fixed rod 113 and the detector, ensuring that the fixed rod 113 and the detector can be completely cleaned. After the cleaning is completed, the staff activates the first push rod 115. The circular plate at the telescopic end of the first push rod 115 moves upward, creating a negative pressure in the liquid storage shell 116 to extract the hydraulic oil in the sleeve 111, thereby driving the piston rod 112 to move upward. The piston rod 112 drives the fixed rod 113 and the probe 114 to move upward, retracting the detector into the sleeve 111 to avoid the detector being damaged by exposure to the outside.

[0049] After retracting the detector into the sleeve 111, the staff moves the device to other positions that need to be detected for detection and fills the previously dug hole.

Four circumferentially distributed chutes are arranged on the lower side of the connecting plate 43.

Fixing blocks 48 are fixedly connected to the middle of the four circumferentially distributed second sliding rods 47. The lower ends of the four circumferentially distributed second sliding rods 47 are jointly slidably connected with an adjusting plate 49. Four circumferentially distributed chutes are arranged on the upper side of the adjusting plate 49. The lower ends of the four second sliding rods 47 are all located in the adjacent chutes, which is used to drive the adjusting plate 49 to rotate reciprocally. A mounting plate 410 is rotatably connected to the upper side of the adjusting plate 49. The mounting plate 410 is provided with circumferentially distributed curved chutes. The four circumferentially distributed second sliding rods 47 are all located in the adjacent curved chutes on the mounting plate 410. The mounting plate 410 is used to drive the four second sliding rods 47 to move synchronously. Sliders 411 are slidably connected to the middle of the inner sides of the four circumferentially distributed fixing blocks 48. Two symmetrically distributed elastic telescopic rods are fixedly connected to the side of the slider 411 away from the adjacent fixing block 48. The telescopic ends of the two symmetrically distributed elastic telescopic rods are jointly fixedly connected with a cleaning plate 412, which is used to prevent the cleaning plate 412 from making hard contact with the adjacent arc plate 23 and causing damage to the cleaning plate 412. A second push rod 413 is fixedly connected to the right part of the lower side of the adjusting plate 49. The telescopic end of the second push rod 413 is fixedly connected with an L-shaped rod 414. An adjusting block 415 is fixedly connected to the lower part of the right second sliding rod 47. The left end of the L-shaped rod 414 is fixedly connected to the right side surface of the adjusting block 415, which is used to drive the right second sliding rod 47 to move leftward. A positioning mechanism is arranged on the slider 411, and the positioning mechanism is used to adjust the position of the adjacent cleaning plate 412. A limiting mechanism is arranged on the adjusting plate 49, and the limiting mechanism is used to separate the annular plate 21 and the transmission plate 22.

[0051] As Figure 11As shown in the figure, the positioning mechanism includes two elastic members 51 symmetrically distributed up and down. The elastic member 51 is an elastic telescopic rod. The symmetrically distributed elastic members 51 are respectively fixed to the upper and lower sides of the adjacent slider 411. The ends of the symmetrically distributed elastic members 51 far from the adjacent slider 411 are both fixed to the adjacent fixed block 48, which is used to ensure that the adjacent cleaning plate 412 is located in the middle of the adjacent fixed block 48 when not affected by external forces. Two positioning blocks 52 symmetrically distributed up and down are fixed to each of the four circumferentially distributed cleaning plates 412. The lower side of the telescopic end of the piston rod 112 and the upper side of the probe 114 are respectively in pressing fit with the adjacent positioning blocks 52. The ends of the symmetrically distributed positioning blocks 52 far from the adjacent slider 411 are bent towards the middle, and the included angles of the symmetrically distributed positioning blocks 52 are all obtuse angles. After being pressed by the probe 114 and the piston rod 112, the adjacent cleaning plate 412 is pushed to move, so that the adjacent cleaning plate 412 is aligned with the fixed rod 113, and the soil adhered to the detector on the fixed rod 113 can be cleaned.

[0052] As Figure 12 As shown in the figure, the limiting mechanism includes a third push rod 61. The third push rod 61 is fixed to the left part of the lower side of the adjusting plate 49. The telescopic end of the third push rod 61 is fixed with a limiting block 62. The third push rod 61 is used to drive the limiting block 62 to move to the right. The limiting block 62 is in limiting cooperation with the drill bit 24. The limiting block 62 is used to separate the annular plate 21 from the transmission plate 22, so that the annular plate 21 can rotate independently, which is convenient for cleaning the detector on the fixed rod 113.

[0053] After the drill bit 24 leaves the drill hole as described above, the drill bit 24 continues to move upward. After the lower side of the sleeve 111 moves above the adjusting plate 49, the operator starts the third push rod 61. The telescopic end of the third push rod 61 pushes the limiting block 62 to move to the right, and the limiting block 62 is moved above the moving path of the drill bit 24. The operator closes the third push rod 61, and the limiting block 62 stops moving. As the drill bit 24 continues to move upward, when the left part of the upper side of the drill bit 24 contacts the lower side of the limiting block 62, the limiting block 62 restricts the drill bit 24 from continuing to move upward. At this time, the annular plate 21 cannot move upward. At this time, the sleeve 111 continues to move upward, and the annular plate 21 repeats the process of separating from the transmission plate 22 as described above. After the annular plate 21 is separated from the transmission plate 22, the operator closes the first motor 13, and the threaded rod 19 stops moving upward. At this time, the operator starts the second push rod 413.

[0054] After the second push rod 413 is started as described above, the telescopic end of the second push rod 413 drives the L-shaped rod 414 to move to the left. The L-shaped rod 414 drives the second slide rod 47 on the right to move to the left through the adjusting block 415. The second slide rod 47 on the right drives the adjacent fixed block 48 to move to the left. The fixed block 48 drives the adjacent slider 411 to move to the left. The slider 411 drives the adjacent cleaning plate 412 to move to the left through the elastic telescopic rod.

[0055] When the second slide bar 47 on the right moves leftward, the second slide bar 47 on the right slides in the chute on the mounting plate 410 and presses against the mounting plate 410, causing the mounting plate 410 to rotate. After the mounting plate 410 rotates, it drives the other three second slide bars 47 to move, and repeats the above process to drive the adjacent cleaning plate 412 to move inward.

[0056] When the above-mentioned cleaning plate 412 moves inward, the cleaning plate 412 moves inward through the gap between the adjacent arc-shaped plates 23. When the second slide bar 47 on the right moves to the leftmost side of the adjacent chute on the mounting plate 410, the second slide bar 47 on the right stops moving leftward, the mounting plate 410 stops rotating, and the other three second slide bars 47 stop moving. At this time, the brush on the cleaning plate 412 contacts the detector on the fixed rod 113, and the staff closes the second push rod 413.

[0057] After the above-mentioned staff closes the second push rod 413, the staff starts the third motor 44. The output shaft of the third motor 44 drives the circular plate to rotate, the circular plate drives the connecting rod 45 to rotate, the connecting rod 45 drives the first slide bar 46 to rotate, and the first slide bar 46 slides in the chute on the upper side of the connecting plate 43, causing the connecting plate 43 to rotate reciprocally. The rotation of the connecting plate 43 presses the four second slide bars 47 through the chute on it, thereby driving the four second slide bars 47 to rotate reciprocally. At this time, since the second push rod 413 has been closed, the second slide bar 47 on the right cannot slide outward along the adjacent chute on the connecting plate 43, making the positions of the four second slide bars 47 fixed on the connecting plate 43. The four second slide bars 47 synchronously drive the adjusting plate 49 and the mounting plate 410 to rotate by pressing the adjusting plate 49 and the chute on the mounting plate 410. The adjusting plate 49 drives the second push rod 413 to rotate synchronously. The second slide bar 47 rotates through the adjacent fixing block 48, and the fixing block 48 drives the adjacent cleaning plate 412 to rotate through the adjacent slider 411. The reciprocating rotation of the cleaning plate 412 enables the brush on it to clean the soil adhered to the fixed rod 113 and the detector.

[0058] During the process of the right cleaning plate 412 moving inwards, the right fixing block 48 drives the adjacent elastic member 51 to move inwards, and the right cleaning plate 412 drives the two adjacent positioning blocks 52 to move inwards. If the arc plate 23 on the right is located on the moving path of the adjacent cleaning plate 412, when the two positioning blocks 52 on the right contact the adjacent arc plate 23, the right cleaning plate 412 cannot continue to move leftwards. The adjacent fixing block 48 continues to move leftwards and compresses the adjacent elastic telescopic rod until the second slide rod 47 on the right stops moving. The staff activates the third motor 44 and repeats the above process to drive the cleaning plate 412 to rotate. After the cleaning plate 412 rotates, the cleaning plate 412 gradually separates from the adjacent arc plate 23. After the cleaning plate 412 separates from the adjacent arc plate 23, at this time, under the push of the adjacent elastic telescopic rod, the cleaning plate 412 moves inwards. The two positioning blocks 52 on the cleaning plate 412 contact the fixed rod 113, and the brush on the cleaning plate 412 contacts the detector, and repeats the above process to clean the soil adhered to the detector. The cleaning plates 412 at other positions repeat the same process.

[0059] During the process of the cleaning plate 412 cleaning the soil, when the adjacent elastic telescopic rod contacts the adjacent arc plate 23, since the annular plate 21 separates from the transmission plate 22, at this time the annular plate 21 can rotate independently, and the elastic telescopic rod can squeeze the adjacent arc plate 23 to move the adjacent arc plate 23, thereby changing the position of the arc plate 23 to prevent damage to the elastic telescopic rod caused by the inability of the arc plate 23 to move after the arc plate 23 contacts the elastic telescopic rod.

[0060] During the process of the above positioning block 52 contacting the fixed rod 113, when the cleaning plate 412 is not aligned with the detector on the fixed rod 113, if the cleaning plate 412 is tilted downwards, after the inclined surface of the lower adjacent positioning block 52 contacts the upper side surface of the probe 114, the positioning block 52 is pushed upwards by the probe 114 and drives the adjacent cleaning plate 412 to move upwards. The cleaning plate 412 drives the adjacent slider 411 to move upwards through the adjacent elastic telescopic rod and squeezes the upper adjacent elastic member 51. If the cleaning plate 412 is tilted upwards, at this time the inclined surface of the upper adjacent positioning block 52 contacts the telescopic end of the piston rod 112, and repeats the above similar process to move the cleaning plate 412 downwards. Then the staff activates the third motor 44 and repeats the above process to clean the detector.

[0061] After the above detector cleaning is completed, the staff turns off the third motor 44 and activates the second push rod 413 and the third push rod 61 to repeat the above reverse process for resetting. After the reset is completed, the staff activates the first push rod 115 to retract the fixed rod 113 and the probe 114 into the sleeve 111. Then the staff activates the first motor 13 again to drive the sleeve 111 to move upwards for resetting.

[0062] Embodiment 3: On the basis of Embodiment 2, as Figure 13 and 14 shown, it further includes an adjusting mechanism. The adjusting mechanism is arranged on the fixing plate 12 and is used to adjust the descending speed of the threaded rod 19. The adjusting mechanism includes a fourth push rod 71. The fourth push rod 71 is fixedly connected to the left part of the lower side surface of the fixing plate 12. The fourth push rod 71 is located on the left side of the first motor 13. The telescopic end of the fourth push rod 71 is fixedly connected with a third rotating sleeve 72. The output shaft of the first motor 13 is in spline connection with the sliding sleeve 14 and is used to drive the sliding sleeve 14 to rotate. A third gear 73 is fixedly connected to the upper side surface of the sliding sleeve 14. The third gear 73 is rotationally connected with the third rotating sleeve 72. The third rotating sleeve 72 is used to drive the third gear 73 to move up and down. A fourth gear 74 is fixedly connected to the upper part of the outer side surface of the threaded sleeve 17. The third gear 73 meshes with the fourth gear 74. The diameter of the third gear 73 is smaller than the diameter of the first gear 15, and the diameter of the fourth gear 74 is larger than the diameter of the second gear 18, which is used to change the descending speed of the drill bit 24 and avoid damage to the device caused by the drill bit 24 still descending at a relatively fast speed when encountering a harder soil layer. A sensor 75 is arranged in the upper part of the sleeve 111, and the sensor 75 is used to detect the resistance received by the drill bit 24.

[0063] When the drill bit 24 starts drilling, if the soil layer in the detection area is relatively soft, the resistance received by the drill bit 24 after contacting the soil layer is small. The transmission plate 22 moves upward relative to the sleeve 111, but the upward movement distance of the transmission plate 22 is small. At this time, the spring between the transmission plate 22 and the sleeve 111 is compressed less, and the transmission plate 22 does not contact the sensor 75. At this time, the drill bit 24 rotates normally and drills downward.

[0064] If the soil layer in the detection area is relatively hard, the resistance received by the drill bit 24 after contacting the soil layer is large. The drilling speed of the drill bit 24 is slower than that when drilling in a soft soil layer, and the downward movement speed of the drill bit 24 decreases. At this time, the upward movement distance of the transmission plate 22 is greater than that in a soft soil layer. During this process, when the transmission plate 22 contacts the sensor 75, the sensor 75 transmits a signal. At this time, the staff turns off the first motor 13 and starts the fourth push rod 71. The telescopic end of the fourth push rod 71 drives the third gear 73 to move upward through the third rotating sleeve 72, and the third gear 73 drives the first gear 15 to move upward through the sliding sleeve 14.

[0065] During the upward movement of the third gear 73 and the first gear 15, the first gear 15 moves upward and gradually separates from the second gear 18. At this time, the third gear 73 and the fourth gear 74 are not in contact. When the first gear 15 loses meshing with the second gear 18, the third gear 73 and the first gear 15 continue to move upward until the third gear 73 is fully meshed with the fourth gear 74. Subsequently, the staff activates the first motor 13, and the third gear 73 drives the fourth gear 74 to rotate. At this time, the rotation speed of the threaded sleeve 17 is less than that in the soft soil layer, reducing the descending speed of the sleeve 111 and preventing the drill bit 24 from descending at a high speed when the detection area is a hard soil layer, which may cause damage to the device.

[0066] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present invention.
