[0002] Ecological restoration is a comprehensive method of repairing polluted environment under the guidance of ecological principles, based on biological restoration, combining various physical restoration, chemical restoration and engineering technical measures to achieve the best effect and lowest cost through optimized combination. When studying ecological restoration plans, it is very necessary to first conduct geological exploration. During the exploration process, exploration equipment is needed to drill the soil to achieve sampling of deep soil.

[0003] A sampler for soil ecological environment restoration is disclosed in the Chinese utility model patent publication number CN211602476U, which includes a first straight plate, the upper and lower ends of the first straight plate are processed with sampling mechanisms, the top of the first straight rod is fixedly connected to the first straight plate, the outer wall of the first straight rod is fixedly connected to a thread, the lower end of the first straight rod is fixedly connected to a rotating block, the right side of the outer wall of the thread is fixedly connected to a baffle, and the lower end of the second straight rod is fixedly connected to the first straight rod. The sampler for soil ecological environment restoration avoids the problem of different pollution sources at different depths and inconvenient detection through the connection and cooperation of the thread, the first straight rod, the second straight rod, the baffle and the rotating block, avoids the situation that the device is prone to deviation during operation through the connection and cooperation of the first threaded sleeve, the cone block and the second threaded sleeve, and avoids the situation that the original sampling technology is more wasteful and time-consuming through the connection and cooperation of the motor, the handle and the turntable.

[0004] When sampling soil samples, the ecological restoration soil sampling device in the above-mentioned prior art drills into the soil through a straight rod (referred to as a drill rod in this application), and the straight rod rotates to drive the thread on the straight rod (referred to as a spiral sheet in this application) to rotate, thereby bringing the soil out of the ground to collect the soil. However, due to the different geological and ecological conditions at different depths, when the sampling device in the prior art is used to sample soil samples, soils at different depths are mixed together, making it impossible for staff to distinguish soil samples at different depths, which brings certain inconveniences to the subsequent soil composition monitoring and sampling work. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a real-time monitoring sampling device for geological ecological restoration.

[0011] A rotary drive device is provided on the lifting drive device, and the rotary drive device is used to drive the rotary discharge bin to rotate at a fixed angle.

[0012] Through the above technical scheme, the drilling rod is driven by the lifting drive device to move and rotate downward, so that the drilling rod and the spiral blade can drill into the soil on the surface, and the soil will slide along the spiral blade and be carried above the surface, so that the soil enters the rotary discharge bin, and then enters the corresponding specimen bin from the discharge port of the rotary discharge bin, so as to collect the soil sample. In addition, when the drilling rod moves downward, the rotary drive device will drive the rotary discharge bin to rotate at equal angles, so that the discharge port can increase with the depth of the drilling rod into the soil, so that the discharge port can face multiple specimen bins.

[0013] Furthermore, a handle is provided on the outer wall of the specimen bin.

[0014] Through the above technical solution, the staff holds the handle to facilitate moving the specimen chamber.

[0015] Furthermore, a positioning column is fixedly connected to a side of the specimen bin facing the hollow seat, a positioning sleeve is fixedly connected to an outer wall of the hollow seat, and the positioning column is correspondingly inserted into the positioning sleeve.

[0016] Through the above technical solution, the positioning column is inserted into the positioning sleeve, so that the specimen chamber is not prone to self-sliding on the movable plate.

[0017] Furthermore, the lifting drive device includes a support plate vertically fixed to one end of the top of the movable plate body, the upper end of the support plate is horizontally fixed to a top plate, a cylinder is vertically installed on the top surface of the top plate, the cylinder rod of the cylinder penetrates the top plate and is fixed to a lifting seat, a motor is vertically installed on the lifting seat, and the output end of the motor is connected to the drill rod drive.

[0018] Through the above technical solution, the cylinder rod of the cylinder is extended and retracted, thereby driving the lifting seat to move vertically, so that the lifting seat drives the drill rod to move up and down, and at the same time the output shaft of the motor rotates, so that the motor drives the drill rod to rotate.

[0019] Furthermore, the rotary drive device includes a mounting plate connected to a side wall of the support plate, the top surface of the mounting plate is rotatably connected to a first pulley, the top of the rotary discharging bin is coaxially fixed with a second pulley, the first pulley and the second pulley are connected via a V-belt transmission, and the lifting seat is provided with an intermittent rotation drive unit for driving the first pulley to rotate intermittently and at equal angles.

[0020] Through the above technical solution, the first pulley is driven to rotate by the intermittent rotation driving unit, so that the first pulley drives the second pulley to rotate through the V-belt, and the second pulley drives the rotating discharge bin to rotate, so that the discharge port of the rotating discharge bin can be directed to different specimen bins, and soil samples of different depths can be put into different specimen bins.

[0021] Furthermore, the intermittent rotation drive unit includes a fixed arm fixedly connected to the side wall of the lifting seat, the end of the fixed arm is vertically fixedly connected to a driving rod, and a rotating sleeve is vertically rotatably connected to the mounting plate, the upper end of the rotating sleeve protrudes above the mounting plate, and the first pulley is coaxially sleeved on the upper end of the rotating sleeve, the driving rod is coaxially inserted into the rotating sleeve, and a plurality of groups of balls are embedded in the periphery of the driving rod in a rotatable manner from top to bottom, the number of balls in each group is two, and the two adjacent groups of balls are staggered on the periphery of the driving rod, and the longitudinal spacing between the two adjacent groups of balls is fixed, and the inner hole of the rotating sleeve is provided with a rolling groove for the balls to engage, and the rolling groove includes a first straight groove, a spiral groove, and a second straight groove connected end to end from top to bottom.

[0022] Through the above technical solution, when the lifting seat moves downward, the lifting seat will drive the driving rod to move downward. When moving downward, the balls on the driving rod will alternately engage with the rolling grooves, so that the rotating sleeve can rotate. When the rotating sleeve rotates, it will drive the first pulley to rotate. When the first pulley rotates, it will drive the second pulley to rotate, so that the rotating discharge bin rotates.

[0023] Furthermore, a mounting tube is vertically connected to the bottom of the mounting plate, the upward side of the mounting tube is open, and a stop column is telescopically installed in the mounting tube, the stop column penetrates the mounting plate and slides freely, a limiting steel ball is rotatably embedded in the upper end of the stop column, and a plurality of stopping grooves for the limiting steel balls to engage are provided on the lower end surface of the first pulley, and a spring is vertically installed in the mounting tube, and the spring has an upward elastic resisting force on the lower end surface of the stop column.

[0024] Through the above technical scheme, when the ball rolls in the rolling groove, it will be able to drive the rotating sleeve to rotate. When the rotating sleeve rotates, the limiting steel ball will be disengaged from the engaging state with the stop groove, so that the rotating sleeve and the first pulley can rotate, so that the limiting steel ball is in rolling contact with the lower end surface of the first pulley. At the same time, the limiting steel ball moves in the direction of being retracted into the inner side of the mounting tube, and the stop column compresses the spring. The spring accumulates elastic potential energy, so that the limiting steel ball can maintain rolling contact with the lower end surface of the first pulley. Conversely, when the stop column moves upward, the limiting steel ball is engaged in the engaging groove, so that the first pulley is not easy to rotate on its own.

[0025] Furthermore, a limit pin is passed through the lower end of the stop column, and a waist-shaped hole for the limit pin to be inserted is opened on the outer wall of the installation tube.

[0026] Through the above technical solution, the limiting pin slides in the waist-shaped hole, so that the stop column will not be separated from the installation tube during the process of assembling the first pulley on the rotating sleeve.

[0027] Furthermore, a short shaft is fixedly connected to one end of the discharge port away from the rotating discharge bin, a dispersion bin is rotatably connected to the short shaft, and a swing unit is provided at the bottom of the dispersion bin.

[0028] Through the above technical solution, the swing unit drives the dispersion bin to swing up and down around the axial direction of the short axis, so that when the rotary discharge bin rotates, the soil samples on the discharge port and the dispersion bin can fall quickly to avoid entering another specimen bin.

[0029] Furthermore, the swing unit includes a floating column fixedly connected to the bottom of the dispersion bin, and a plurality of protrusions are fixedly connected to the top surface of the specimen bin, and the protrusions are used in conjunction with the floating column.

[0030] Through the above technical solution, when the rotary discharge bin rotates, the bottom end of the floating column will slide from the upper surface of the specimen bin to the surface of the protrusion, thereby causing the floating column to swing upward, allowing the dispersion bin to swing around the axial direction of the pivot.

[0031] The beneficial effects of the present invention are as follows:

[0032] In the present invention, the drilling rod is driven by the lifting drive device to move downward and rotate, so that the drilling rod and the spiral blade can drill into the soil on the surface of the ground, and the soil will slide along the spiral blade and be taken away to the surface, so that the soil enters the rotating discharge bin, and then enters the corresponding specimen bin from the discharge port of the rotating discharge bin, so as to collect the soil sample. In addition, when the drilling rod moves downward, the rotating drive device will drive the rotating discharge bin to rotate at an equal angle, so that the discharge port can increase with the depth of the drilling rod into the soil, so that the discharge port can face multiple specimen bins;

[0033] In the present invention, when the lifting seat moves downward, the lifting seat will drive the driving rod to move downward. When moving downward, the balls on the driving rod will alternately engage with the rolling grooves, so that the rotating sleeve can rotate. When the rotating sleeve rotates, it will drive the first pulley to rotate. When the first pulley rotates, it will drive the second pulley to rotate, so that the rotating discharge bin rotates;

[0034] In the present invention, when the ball rolls in the rolling groove, it will be able to drive the rotating sleeve to rotate. When the rotating sleeve rotates, the limiting steel ball will be disengaged from the engaging state with the stopping groove, so that the rotating sleeve and the first pulley can rotate, so that the limiting steel ball is in rolling contact with the lower end surface of the first pulley. At the same time, the limiting steel ball moves in the direction of being retracted into the inner side of the mounting tube, and the stopping column compresses the spring. The spring accumulates elastic potential energy, so that the limiting steel ball can maintain rolling contact with the lower end surface of the first pulley. Conversely, when the stopping column moves upward, the limiting steel ball is engaged in the engaging groove, so that the first pulley is not easy to rotate on its own.

[0048] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] like Figure 1-Figure 12 As shown, this embodiment provides a real-time monitoring sampling device for geological ecological restoration, including a movable plate body 1, a plurality of rollers are installed at the bottom of the movable plate body 1, a support plate 10 is vertically welded to one end of the movable plate body 1, a top plate 14 is horizontally fixedly connected to the upper end of the support plate 10, a cylinder 13 is vertically installed on the top of the end of the top plate 14 away from the support plate 10, a cylinder rod of the cylinder 13 penetrates the top plate 14 and slides freely on the top plate 14, and a lifting seat 16 is connected to the end of the cylinder rod of the cylinder 13, a motor 15 is vertically installed on the lifting seat 16, a drill rod 18 is fixedly connected to the output shaft of the motor 15, and the drill rod 18 is coaxial with the output shaft of the motor 15, and a spiral sheet 26 is fixedly mounted on the periphery of the lower end of the drill rod 18, and a free space groove for the spiral sheet 26 to pass freely is opened on the top of the movable plate body 1;

[0050] Combination Figure 1 , Figure 5As shown, the top of the movable plate body 1 is fixedly connected with a hollow seat 21, and the hollow seat 21 is connected with the air avoidance groove. In addition, the spiral piece 26 can freely pass through the middle hole of the hollow seat 21. In addition, the maximum diameter of the spiral piece 26 is consistent with the middle hole diameter of the hollow seat 21, and the diameter of the lower side of the spiral piece 26 is smaller than the diameter of the upper side of the spiral piece 26. Four positioning sleeves 28 are fixedly connected to the periphery of the hollow seat 21. The end of the positioning sleeve 28 is provided with a mounting hole in the form of a blind hole. A positioning column 27 is inserted and installed in the mounting hole. The end of the positioning column 27 that passes through the positioning sleeve 28 is welded with a specimen bin 2. The outline of the specimen bin 2 is fan-shaped when viewed from above. In addition, the top of the specimen bin 2 is open, and a rotating discharge bin 20 is rotatably mounted on the upper end of the hollow seat 21. The rotating discharge bin 2 0 is hollow inside, and a through hole is provided on its end face for the drill rod 18 to pass freely. In addition, a discharge port 3 is provided on the periphery of the rotary discharge bin 20, and the discharge port 3 is connected with the inner cavity of the rotary discharge bin 20. In addition, a handle 4 is welded on the outer wall of the specimen bin 2, so that when the specimen bin 2 is moved, the specimen bin 2 can be moved more conveniently by the handle 4. The drill rod 18 moves downward and is driven to rotate by the motor 15, so that the drill rod 18 and the spiral piece 26 can drill into the soil on the surface of the ground, and the soil will slide upward along the spiral piece 26 and be taken away to above the surface, so that the soil enters the rotary discharge bin 20, and then enters the corresponding specimen bin 2 from the discharge port 3 of the rotary discharge bin 20, so as to collect the soil sample;

[0051] Combination Figures 1 to 6 As shown, the side of the support plate 10 facing the rotary discharge bin 20 is connected to the mounting plate 9 by means of screws, and the end of the mounting plate 9 away from the support plate 10 is rotatably connected to a rotating sleeve 22 by means of a mounting bearing, the upper end of the rotating sleeve 22 protrudes above the top surface of the mounting plate 9, and the upper end of the rotating sleeve 22 is fixedly sleeved with a first pulley 8, and an annular flange 6 is coaxially welded to the top surface of the rotary discharge bin 20, and a second pulley 19 is fixedly sleeved on the periphery of the annular flange 6, and the second pulley 19 is transmission-connected with the first pulley 8 by a V-belt 17, so that when the first pulley 8 rotates, the V-belt 17 drives the second pulley 19 to rotate synchronously, and in addition, the diameters of the first pulley 8 and the second pulley 19 are consistent, so that the angular velocity of the first pulley 8 during rotation is consistent with the angular velocity of the second pulley 19 during rotation, that is, the number of revolutions of the first pulley 8 and the second pulley 19 is consistent;

[0052] A fixed arm 12 is welded horizontally to the side wall of the lifting seat 16, and a driving rod 11 extending downward is vertically fixed to the end of the fixed arm 12. A rotating sleeve 22 is vertically rotatably connected to the mounting plate 9. The upper end of the rotating sleeve 22 protrudes above the mounting plate 9, and the first pulley 8 is coaxially sleeved on the upper end of the rotating sleeve 22. The driving rod 11 coaxially penetrates into the rotating sleeve 22. Four groups of balls 24 are rotatably embedded in the periphery of the driving rod 11 from top to bottom. The number of balls 24 in each group is two, and the adjacent two groups of balls 24 are alternately rotated. The balls 24 of two adjacent groups are staggered around the driving rod 11, and the longitudinal spacing between the balls 24 is fixed. The inner hole of the rotating sleeve 22 is provided with a rolling groove 39 for the balls 24 to engage. The rolling groove 39 includes a first straight groove, a spiral groove and a second straight groove connected end to end from top to bottom. The surface of the moving plate 1 is provided with an avoidance groove 7 for the driving rod 11 to pass freely. When the balls 24 move downward with the driving rod 11, the balls 24 will roll from the first straight groove to the spiral groove. When the balls 24 roll in the spiral groove, the balls 24 can drive the rotating sleeve 22 to rotate, so that the rotating sleeve 22 rotates a fixed angle, so that the first pulley 8 rotates a fixed angle (in this embodiment, the fixed angle is set to 90°), and then the first pulley 8 drives the V-belt 17 and the second pulley 19 to rotate. When the second pulley 19 rotates, it will synchronously drive the annular flange 6 and the rotating discharge bin 20 to rotate, so that the direction of the discharge port 3 on the rotating discharge bin 20 can be changed, that is, the mouth direction of the discharge port 3 rotates from one specimen bin 2 to the next specimen bin 2. In addition, since the longitudinal spacing of the two adjacent groups of balls 24 is consistent, only when the drill rod 18 continues to drill into the soil to a fixed depth, the next group of balls 24 will start to mesh with the rolling groove 39, and then the rotating sleeve 22 will rotate. In this way, when the drill rod 18 is drilling soil samples corresponding to different depths, it can change the mouth direction of the discharge port 3, thereby facilitating the collection of soil samples at different depths;

[0053] In addition, a mounting cylinder 23 is vertically connected to the bottom of the mounting plate 9, and the upper side of the mounting cylinder 23 is open, and a stop column 33 is telescopically inserted and installed in the mounting cylinder 23. The stop column 33 penetrates the mounting plate 9 and slides freely. A limit steel ball 36 is rotatably embedded in the upper end of the stop column 33. Four stop grooves 37 for the limit steel ball 36 to engage are opened on the lower end surface of the first pulley 8. The four stop grooves 37 are arranged on the first pulley 8 in an array along the axial direction of the first pulley 8. A spring 34 is vertically installed, and the spring 34 has an upward elastic force on the lower end surface of the stop column 33. In the initial state, the spring 34 has an upward elastic force on the stop column 33, thereby causing the stop column 33 to move upward and causing the limiting steel ball 36 to roll in contact with the lower end surface of the first pulley 8. A limiting pin 35 is penetrated at the lower end of the stop column 33, and a waist-shaped hole 38 for the limiting pin 35 to be inserted is opened on the outer wall of the installation cylinder 23. The limiting pin 35 is inserted in the waist-shaped hole 38. 8 slides and limits, so that when the first pulley 8 is assembled, the stop column 33 will not be subjected to the upward elastic force of the spring 34, but moves upward, thereby causing the stop column 33 to be separated from the installation tube 23. In this way, when the first pulley 8 rotates, the limiting steel ball 36 will be resisted by the stopping groove 37, so that the limiting steel ball 36 drives the stop column 33 to move downward, so that the stop column 33 slides downward in the installation tube 23, so that the first pulley 8 can rotate, The limiting steel ball 36 rolls on the lower end surface of the first pulley 8 until the first pulley 8 rotates 90°, and then the limiting steel ball 36 rolls into another stop groove 37 again. At this time, the spring 34 exerts an elastic force on the stop column 33, so that the stop column 33 moves upward and the limiting steel ball 36 is engaged in the stop groove 37. At this time, the ball 24 on the driving rod 11 is disengaged from the engagement state with the rolling groove 39, so that the rotating sleeve 22 does not rotate.

[0054] Combination Figure 5 , Figure 6 and Figure 7As shown, short shafts 31 are fixedly connected to the outer walls of both sides of one end of the discharge port 3 away from the rotating discharge bin 20, and a dispersion bin 5 is rotatably connected to the short shaft 31. The outer contour of the dispersion bin 5 is U-shaped, and a rotating hole for the short shaft 31 to be inserted is opened at one end of the dispersion bin 5. The short shaft 31 rotates freely in the rotating hole. After the dispersion bin 5 swings downward around the axial direction of the short shaft 31 to be in place, the dispersion bin 5 and the discharge port 3 are in a straight line, so that the soil sample on the discharge port 3 can slide along the surface of the discharge port 3 to the surface of the dispersion bin 5, and slide from the dispersion bin 5 to the specimen bin 2. A floating column 32 is fixedly connected to the bottom of the dispersion bin 5, and a plurality of protrusions 25 are fixedly connected to the top surface of the specimen bin 2. The protrusions 25 Used in conjunction with the floating column 32, a fixed sleeve 29 is fixedly connected to the outer wall of the dispersion bin 5, the fixed sleeve 29 is coaxial with the short shaft 31, and the outer diameter of the fixed sleeve 29 is originally larger than the outer diameter of the short shaft 31, and a vortex spring 30 is installed in the fixed sleeve 29, the vortex spring 30 is wrapped around the periphery of the short shaft 31, and the two ends of the vortex spring 30 in the elastic force direction are respectively fixed to the periphery of the short shaft 31 and the inner wall of the fixed sleeve 29. In the initial state, the elastic potential energy of the vortex spring 30 will drive the short shaft 31 to rotate, and drive the dispersion bin 5 to rotate downward, so that the surface of the dispersion bin 5 is flush with the surface of the discharge port 3, and the bottom of the floating column 32 is in contact with the upper surface of the specimen bin 2.

[0055] The working principle of this embodiment is as follows:

[0056] The movable plate 1 is moved to the surface of the area to be sampled, and then the cylinder 13 is started, the cylinder rod of the cylinder 13 is extended, and at the same time, the motor 15 is energized, and the output shaft of the motor 15 rotates, so that the output shaft of the motor 15 drives the drill rod 18 to rotate, and the cylinder rod of the cylinder 13 is extended, so that the drill rod 18 drills into the ground and drills a sampling hole in the ground. At the same time, the spiral piece 26 also rotates synchronously, so that the spiral piece 26 can bring the soil in the sampling hole away to the sampling hole. Specifically, the soil will slide upward along the spiral surface of the spiral piece 26 into the hollow seat 21 and the rotary discharge bin 20. As the soil below continues to slide upward, the soil sample enters the dispersion bin 5 from the discharge port 3 of the rotary discharge bin 20, and slides along the surface of the dispersion bin 5 to the specimen bin 2, so that the soil sample can be collected;

[0057] As the drill rod 18 continues to move downward, the ball 24 of the drill rod 18 will be stuck in the first straight groove of the rotating sleeve 22 (in the initial state, the ball 24 at the bottom of the driving rod 11 corresponds to the position of the first straight groove of the rotating sleeve 22). When the ball 24 rolls from the first straight groove to the spiral groove, since the rotating sleeve 22 is rotatably connected to the mounting plate 9, and the driving rod 11 and the fixed arm 12 are in a relatively static state, the ball 24 will drive the rotating sleeve 22 to rotate. When the rotating sleeve 22 rotates, it will drive the first pulley 8 to rotate. When the ball 24 rolls from one end of the spiral groove to the other end of the spiral groove, the ball 24 will drive the rotating sleeve 22 to rotate 90° , then the ball 24 rolls from the spiral groove to the second straight groove, and continues to move downward with the drill rod 18, so that the ball 24 is out of contact with the rotating sleeve 22. When the first pulley 8 rotates, the first pulley 8 drives the V-belt 17 and the second pulley 19 to rotate. When the second pulley 19 rotates, it will synchronously drive the annular flange 6 and the rotating discharge bin 20 to rotate, so that the direction of the discharge port 3 on the rotating discharge bin 20 can be changed, that is, the direction of the mouth of the discharge port 3 rotates from one specimen bin 2 to the next specimen bin 2, so that when the drilling depth of the drill rod 18 increases, the mouth of the discharge port 3 can alternately rotate to multiple specimen bins 2;

[0058] At the same time, when the first pulley 8 rotates, the limiting steel ball 36 will be resisted by the stop groove 37, so that the limiting steel ball 36 drives the stop post 33 to move downward, so that the stop post 33 slides downward in the installation cylinder 23, so that the first pulley 8 can rotate, so that the limiting steel ball 36 rolls on the lower end surface of the first pulley 8. Until the first pulley 8 rotates 90°, the limiting steel ball 36 will roll into another stop groove 37 again. At this time, the spring 34 exerts an elastic force on the stop post 33, thereby causing the stop post 33 to move upward and the limiting steel ball 36 to engage in the stop groove 37. At this time, the ball 24 on the driving rod 11 is out of the engagement state with the rolling groove 39, so that the rotating sleeve 22 does not rotate;

[0059] In addition, when the rotating discharge bin 20 rotates, the discharge port 3 will rotate synchronously, causing the floating column 32 to rotate relative to the specimen bin 2, and the floating column 32 will slide from the top surface of the specimen bin 2 to the surface of the protrusion 25, and the floating column 32 will be lifted up by the protrusion 25, thereby driving the dispersion bin 5 to swing upward around the axial direction of the short shaft 31, and causing the short shaft 31 to contract the spiral spring 30. The spiral spring 30 accumulates elastic potential energy. When the floating column 32 slides from the surface of the protrusion 25 to the top surface of the specimen bin 2, the spiral spring 30 accumulates elastic potential energy. The elastic potential energy stored in the scroll spring 30 is released, so that the scroll spring 30 drives the short shaft 31 to rotate in the opposite direction, thereby causing the dispersion bin 5 to swing downward around the axial direction of the short shaft 31, and this is repeated, so that during the rotation of the rotary discharge bin 20, the dispersion bin 5 will swing back and forth up and down around the axial direction of the short shaft 31, thereby causing the soil samples on the discharge port 3 and the dispersion bin 5 to be shaken off and fall into the specimen bin 2, thereby preventing part of the soil sample from being brought into the next specimen bin 2 during the rotation of the rotary discharge bin 20;

[0060] After the specimens are collected, the staff holds the handle 4 and moves the specimen bin 2 away from the hollow seat 21, so that the positioning column 27 is disengaged from the positioning sleeve 28, and the soil sample in the specimen bin 2 can be collected. In addition, the cylinder rod of the lifting cylinder 13 is shortened and drives the lifting seat 16 to move upward and reset, so that the drill rod 18 is separated from the sampling hole, thereby completing the collection of a soil sample.
