Description

Technical Field

[0001] The present invention relates to the field of geographic information acquisition technology, and in particular to a geographic information acquisition surveying and mapping device and a surveying and mapping method. Background Art

[0002] Geographic information refers to the general term for facts and knowledge that characterize the quantity, quality, distribution characteristics, mutual connections and laws of change of various elements in the geographical environment. It covers all information related to spatial position, including the connection or law between the inherent characteristics such as quality, quantity, distribution and so on of objects on the earth's surface and the surrounding environment. When collecting and mapping geographic information, it is also necessary to sample and retain the soil in the current geographical environment for later analysis.

[0003] In the process of collecting geographic information, sampling in the current environment is a systematic and scientific workflow in the actual operation process, which aims to ensure that the collected soil samples can truly and accurately reflect the soil characteristics and information of the target area. After clarifying the needs of geographic information collection, sampling is carried out at the current location through the prepared sampling equipment.

[0004] During the entire sampling process, when the staff used the prepared handheld sampling equipment to drill and sample the soil, the entire drilling process was stabilized by the staff's hand-held device, so that the sampling equipment had no stable external support during the drilling process, making the equipment prone to slight tilt and shaking during the drilling process. In this case, it is easy to cause deviations in the final soil samples taken, affecting the subsequent analysis of the soil samples to obtain the various elements of the geographical environment and soil distribution characteristics within the geological area.

[0021] To achieve the above object, the present invention provides the following technical solution: a geographic information collection and mapping device and a mapping method, comprising the following steps:

[0022] First, the motor drives the rotating shaft and the square telescopic shaft to rotate, and the sleeve block arranged on the square telescopic shaft drives the inner screw barrel and the outer screw barrel to descend synchronously. The sampling barrel drives the lifting ring plate to descend as a whole through the engagement between the annular groove and the connecting clamping plate, so that the piercing plate arranged on the lifting ring plate is separated from the contact between the protective shell, and the piercing plate can be opened under the action of the telescopic spherical rod and the movable block;

[0023] Then, as the sampling tube moves, the piercing plate is driven to penetrate into the soil to stabilize the entire moving seat. After the rebound torsion plate on the L-shaped support plate contacts, the lifting ring plate is released from the engagement with the sampling tube as a whole, so that it stays at the current position and does not continue to fall.

[0024] The square telescopic shaft driven by the motor will drive the inner screw barrel and the outer screw barrel to move in turn under the action of the sleeve block, so that the sampling barrel can enter the soil and sample the soil;

[0025] Finally, the driving motor rotates in the opposite direction to reset the sampling tube. At the same time, the sampling tube will rise and reset under the action of the connecting clamping plate set on the annular groove and the lifting ring plate, and the piercing plate will be changed from the open state to the retracted state, completing the entire sampling process.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The present invention cooperates with the sampling tube through the insertion plate arranged on the lifting ring plate, so that when the sampling tube descends, the lifting ring plate can be driven to descend synchronously, so that the inserted plate is separated from the contact between the protective shell and the inserted plate is changed from the initial storage state to the open state. At the same time, when the sampling tube continues to move, the inserted plate is firmly inserted into the soil around the sampling tube, providing a stable support effect, avoiding the sampling tube from shaking slightly when the sampling tube is extended into the soil for sampling. At the same time, during the whole stabilization process, the inserted plate stably supports the entire moving seat, avoiding the rotating moving seat of the surveying instrument arranged on the fixed frame when surveying and mapping, which affects the surveying and mapping results;

[0028] 2. At the same time, during the whole sampling process, through the screw connection between the inner screw barrel and the outer screw barrel, under the clamping action between the elastic extension rod and the penetrating arc groove, the inner screw barrel and the outer screw barrel will be synchronously lowered under the action of the sleeve block, and then after the elastic extension rod releases the clamping action between the inner screw barrel and the inner screw barrel, the inner screw barrel will be extended from the inside of the outer screw barrel, and the inner screw barrel will push the sampling barrel, thereby extending the entire length of the sampling barrel extending into the ground;

[0029] 3. At the same time, during the entire sampling process, the sampling tube can rotate by itself under the drive of the square telescopic shaft, and cooperate with the push of the inner screw barrel, so that the sampling tube can continuously move toward the underground during the rotation process, and the soil in contact is cut by the provided cutting teeth, which can not only make the sampling tube easily penetrate into the underground soil, but also the rotating cutting teeth can shear and cut some plant roots in the underground soil, so as to avoid these plant roots pulling the soil sample when the sampling tube is subsequently taken out from the soil, resulting in the failure of the final sampling.

[0030] 4. During the entire resetting process of the piercing plate, the contact between the matching fixed plate and the rebound twist plate will not affect the rebound twist plate, so that when the sampling tube is rising and resetting, the lifting ring plate can be re-engaged with the annular groove on the sampling tube through the connecting clamping plate, and reset under the drive of the sampling tube, avoiding the need for manual resetting by the staff.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1

[0046] See also Figures 1 to 7 , which is the first embodiment of the present invention, provides a technical solution: a geographic information collection and mapping device, comprising a mobile seat 1 and a fixed frame 2 arranged on the mobile seat 1, a surveying instrument 3 is arranged on the fixed frame 2 away from the mobile seat 1, and the surveying instrument 3 is installed on the upper surface of the fixed frame 2. After the staff pushes the mobile seat 1 to the designated position, the geographic space data in the current area is collected, stored and processed by the surveying instrument 3. A sampling component 4 is arranged on the mobile seat 1, and the sampling component 4 is used to sample and collect soil under the geology;

[0047] The mobile seat 1 is provided with a positioning and fixing component 5, which is used to fix the mobile seat 1 as a whole under the drive of the sampling component 4. The positioning and fixing component 5 will automatically open after moving, and then penetrate into the soil under the continued drive of the sampling tube 41, so as to fix the mobile seat 1 as a whole.

[0048] The positioning and fixing assembly 5 includes a protective shell 51 disposed on the movable seat 1. The protective shell 51 is provided with an array of square protrusions inside. The protrusions come into contact with one side of the piercing plate 53 after passing through the lifting ring plate 52, so that the piercing plate 53 is parallel to the sampling tube 41. When the lifting ring plate 52 is driven by the sampling tube 41 to move, the piercing plate 53 will gradually break away from the contact with the protrusions, so that the piercing plate 53 changes from the storage state to the open state. The lifting ring plate 52 is movably provided inside the protective shell 51.

[0049] The lifting ring plate 52 is provided with a piercing plate 53 in an array on one side close to the moving seat 1, and the piercing plate 53 and the lifting ring plate 52 are in a rotational connection relationship, one section of the piercing plate 53 is a V-shaped opening, and in order to facilitate the piercing plate 53 to be able to smoothly penetrate into the soil, the end opening away from the lifting ring plate 52 is a sharp piercing end. After the lifting ring plate 52 moves, the piercing plate 53 will be out of contact with the protrusions provided on the protective shell 51, so that the piercing plate 53 pops out under the action of the first spring 58 to form a certain opening angle, so that when it continues to descend, the piercing plate 53 will penetrate into the soil to stabilize the entire moving seat 1. In order to prevent the surveying and mapping instrument 3 from shaking during surveying, a through slot is provided on the side of the piercing plate 53 away from the V-shaped opening, through which the movable block 57 is engaged and slid, and an L-shaped support plate 54 is arranged in an array on the lifting ring plate 52, and a through slot is provided in one section of the L-shaped support plate 54. The L-shaped support plate 54 is fixed with the lifting ring plate 52, so that the sleeve rod 55 and the telescopic spherical rod 56 arranged thereon can provide stable support for the piercing plate 53, and can also satisfy the piercing plate 53 to swing at a certain angle, forming a certain inclination angle with the ground, so as to realize the transformation of the piercing plate 53 from the storage state to the open state;

[0050] A sleeve rod 55 is provided on the side of the L-shaped support plate 54 close to the piercing plate 53, and the sleeve rod 55 is rotatably engaged with the piercing plate 53. A telescopic spherical rod 56 is movably provided on the side of the L-shaped support plate 54 close to the piercing plate 53, and the telescopic spherical rod 56 is located directly below the sleeve rod 55. The telescopic spherical rod 56 is engaged with the L-shaped support plate 54 and the movable block 57 through the spherical connecting ends provided at both ends. When the telescopic spherical rod 56 can rotate freely, the two ends of the telescopic spherical rod 56 will not be separated from the connection between the L-shaped support plate 54 and the movable block 57.

[0051] A movable block 57 is movably provided at one end of the telescopic spherical rod 56 away from the L-shaped support plate 54, and the movable block 57 and the telescopic spherical rod 56 are rotatably connected through a spherical port. In the process of satisfying the rotation of the telescopic spherical rod 56, the movable block 57 and the telescopic spherical rod 56 will not be separated. Small clamping blocks are provided on both sides of the movable block 57. Through the clamping between the small clamping blocks and the piercing plate 53, the piercing plate 53 can be opened by the first spring 58 in the absence of external force, and finally form an opened state. The movable block 57 is movably engaged with the piercing plate 53, and the telescopic spherical rod 56 is provided with a first spring 58, and the two ends of the first spring 58 are against the spherical end of the telescopic spherical rod 56.

[0052] The positioning and fixing assembly 5 includes a clamping assembly 6 , which is in contact with the L-shaped supporting plate 54 and is used to control the clamping and disengagement between the lifting ring plate 52 and the sampling assembly 4 .

[0053] The clamping assembly 6 includes a first extension rod 61 disposed on the L-shaped support plate 54, and an arc-shaped push plate 62 is disposed at one end of the first extension rod 61 away from the L-shaped support plate 54. One side of the arc-shaped push plate 62 has an arc-shaped slope, and the slope is in contact with the provided moving rod 64, but the contact position is not the top of the slope, so that the moving rod 64 can apply pressure to the arc-shaped push plate 62 by descending, so that the arc-shaped push plate 62 is displaced;

[0054] The arc-shaped push plate 62 is provided with a connecting snap-fit ​​plate 63 at one end away from the first extension rod 61. The connecting snap-fit ​​plate 63 is used to cooperate with the annular groove 411 provided on the sampling tube 41 through the provided triangular contact end. The triangular contact end provided on the connecting snap-fit ​​plate 63 is contracted inwardly to the left and right, while the upper and lower sides are normal planes. When the sampling tube 41 descends, it can be synchronously descended through the engagement between the connecting snap-fit ​​plate 63 and the sampling tube 41. When the provided moving rod 64 descends, the arc-shaped push plate 62 can be driven to drive the connecting snap-fit ​​plate 63 to move, so that the connecting snap-fit ​​plate 63 is separated from the engagement relationship with the sampling tube 41, so that the entire lifting ring plate 52 stays at the current position.

[0055] The L-shaped support plate 54 is provided with a movable rod 64, which is plugged into the L-shaped support plate 54 through the notch on the L-shaped support plate 54, so that the movable rod 64 can slide up and down inside the notch on the L-shaped support plate 54. At the same time, the contact between the movable rod 64 and the arc-shaped push plate 62 prevents the movable rod 64 from falling down at will. The movable rod 64 will only be displaced when it is squeezed, and the entire arc-shaped push plate 62 is squeezed at the same time, so that the arc-shaped push plate 62 drives the connecting clamping plate 63 to be displaced. The first extension rod 61 is provided with a second spring 65 on the outside. The second spring 65 is used to provide elastic force to reset the arc-shaped push plate 62 when the movable rod 64 is not squeezed by external force.

[0056] A rebound torsion plate 541 is symmetrically and movably arranged on the L-shaped support plate 54, and the rebound torsion plate 541 is rotatably connected to the L-shaped support plate 54 by a connecting rod. The rebound torsion plate 541 is L-shaped, and the connection has the functions of one-way rotation and rebound. A torsion spring is arranged at the connection of the rebound torsion plate 541, and a shorter section is hinged inside a through slot opened in a longer section, so that when the shorter section rotates, only one-way rotation can be performed. At the same time, a top rod is arranged on the rebound torsion plate 541 to cooperate with the arc groove arranged on the L-shaped support plate 54, so that the entire rebound torsion plate 541 will not rotate randomly when not in operation. A fixing rod 542 is arranged on the side of the rebound torsion plate 541 away from the L-shaped support plate 54, and the fixing rod 542 is arranged at the end of the rebound torsion plate 541 where the shorter section is located.

[0057] The movable seat 1 is provided with an annular matching plate 11, and a notch is provided on the annular matching plate 11 for facilitating the opening of the piercing plate 53, so that when the piercing plate 53 is opened, the annular matching plate 11 will not affect it, and an array of matching fixing plates 12 are provided on the annular matching plate 11, and the matching fixing plates 12 are used to cooperate with the fixing rods 542 arranged on the rebound torsion plate 541 when the L-shaped support plate 54 drives the rebound torsion plates 541 on both sides to descend, so that the rebound torsion plate 541 rotates as a whole, and contacts with the movable rod 64 during the rotation of the rebound torsion plate 541, so that the movable rod 64 squeezes the arc-shaped pushing plate 62 to displace, so that the connecting clamping plate 63 is displaced, so that the connecting clamping plate 63 is separated from the clamping action between the sampling tube 41, so that when the subsequent sampling tube 41 continues to descend, the entire lifting ring plate 52 will not be driven to move;

[0058] Limit rods 13 are arranged in an array on one side of the annular matching plate 11 close to the lifting ring plate 52 , and the end of the limit rods 13 away from the annular matching plate 11 is fixedly connected to the protective shell 51 , and the limit rods 13 are slidably engaged with the lifting ring plate 52 .

[0059] A driving assembly 7 is provided on the side of the fixed frame 2 close to the protective shell 51, and a power supply 9 is provided on the side of the movable base 1 close to the fixed frame 2. The power supply 9 provides power to the motor 71 and the surveying instrument 3 through the provided wires. A supporting plate 21 is provided on the side of the fixed frame 2 close to the protective shell 51. The supporting plate 21 is used to support and fix the motor 71 to prevent the motor 71 from shaking as a whole when driving the rotating shaft 72 to rotate.

[0060] During use, first, the mobile seat 1 is moved to the area to be surveyed and mapped, and the surveying instrument 3 is turned on to survey the topography of the current location. Then, the entire sampling tube 41 is driven to rotate by the provided driving assembly 7, and the telescopic assembly 8 is cooperated to increase the length of the tube extended into the ground. When the sampling tube 41 descends, the entire lifting ring plate 52 is driven to move by the connecting clamping plate 63 provided on the L-shaped supporting plate 54. When the piercing plate 53 provided on the lifting ring plate 52 is separated from the contact with the protrusion on the protective shell 51, the piercing plate 53 will be opened under the action of the telescopic spherical rod 56 and the first spring 58, so that the rear When continuing to move, the opened piercing plate 53 can penetrate into the soil to stabilize the entire moving base 1 and prevent the surveying instrument 3 from shaking during the surveying process. At the same time, when the rebound torsion plate 541 set on the L-shaped support plate 54 contacts with the matching fixed plate 12 through the fixed rod 542, the rebound torsion plate 541 will rotate to squeeze the moving rod 64 to descend. As the moving rod 64 descends, the arc-shaped pushing plate 62 is displaced, driving the connecting clamping plate 63 to be displaced, so that the entire lifting ring plate 52 stays at the current position and no longer moves, and the sampling tube 41 continues to move toward the ground to complete the entire sampling process.

[0061] Example 2

[0062] See also Figures 1 to 8 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:

[0063] The driving assembly 7 includes a motor 71 arranged on one side of the supporting fixed plate 21, a rotating shaft 72 is arranged on one side of the motor 71, and a square telescopic shaft 73 is arranged at one end of the rotating shaft 72 away from the motor 71. The square telescopic shaft 73 is telescopic. When the motor 71 drives the rotating shaft 72 to rotate, the square telescopic shaft 73 can not only rotate synchronously, but also telescope to provide a transmission distance. A cross support frame 74 is arranged at one end of the square telescopic shaft 73 away from the rotating shaft 72, and a spiral stirring plate 75 is arranged on the cross support frame 74. The spiral stirring plate 75 is used to break up the soil after contacting the soil, so that the sampling tube 41 can be easily taken out from the soil when it is reset later.

[0064] A telescopic assembly 8 is provided on one side of the cross support frame 74 close to the motor 71 , and the telescopic assembly 8 is used to provide a sufficient telescopic distance for facilitating sampling.

[0065] The sampling assembly 4 includes a sampling barrel 41 arranged at one end of the cross support frame 74 away from the square telescopic shaft 73, a sampling box 42 is movably arranged inside the sampling barrel 41, the sampling box 42 is plugged into the sampling barrel 41, and the sampling box 42 is placed inside the sampling barrel 41 through the plug-in action of the plug-in slot provided in the sampling barrel 41 and the sampling box 42, and the inner diameter of the sampling box 42 is consistent with the inner diameter of the sampling barrel 41, and a cutting tooth 43 is arranged at one end of the sampling barrel 41 away from the cross support frame 74, and the cutting tooth 43 is used to perform annular cutting on the contacted soil when the sampling barrel 41 is driven by the cross support frame 74 to rotate, so that the cut soil can enter the interior of the sampling barrel 41 very conveniently;

[0066] A semi-ring limit plate 44 is symmetrically arranged inside the sampling barrel 41, and the semi-ring limit plate 44 and the sampling barrel 41 are engaged and slid. The semi-ring limit plate 44 is inserted into the limit hole on the sampling box 42 by sliding, so as to avoid the sampling box 42 sliding inside the sampling barrel 41 during the whole sampling process, which leads to the final sampling failure. An annular groove 411 is provided on the sampling barrel 41, and the annular groove 411 is used to contact with the connecting engaging plate 63, so that when the sampling barrel 41 is descending, it can drive the lifting ring plate 52 to move, thereby opening the piercing plate 53.

[0067] During use, when the motor 71 drives the rotating shaft 72 and the square telescopic shaft 73 to rotate synchronously, the sampling tube 41 will be driven to descend. After the cutting teeth 43 arranged at one end of the sampling tube 41 come into contact with the soil, the soil is cut to facilitate the sampling tube 41 to better enter the soil for sampling. At the same time, the spiral stirring plate 75 arranged on the cross support frame 74 can break up the soil in the upper layer of the sampling area, so as to facilitate the subsequent removal of the sampling tube 41 from the soil. When the sampling is completed and the sampling tube 41 is reset, the connecting clamping plate 63 is re-inserted into the annular groove 411 of the sampling tube 41, and is driven by the sampling tube 41 to rise. During the process, the fixed rod 542 on the rebound twist plate 541 will come into contact with the matching fixed plate 12 again. At this time, the shorter section on the rebound twist plate 541 will rotate, thereby preventing the entire rebound twist plate 541 from rotating to squeeze the movable rod 64. After the sampling tube 41 returns to the initial position, the staff can release the limiting effect of the sampling tube 41 on the sampling box 42 by sliding the two semi-ring limiting plates 44, and then pull the sampling box 42 out of the sampling tube 41, transfer the soil inside to a sealed bag for sealing, and then put the sampling box 42 into the sampling tube 41 again, and slide the two semi-ring limiting plates 44 to limit the sampling box 42.

[0068] The remaining structures are the same as those of Example 1.

[0069] Example 3

[0070] See also Figures 1 to 10 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that:

[0071] The telescopic assembly 8 includes a sleeve block 81 arranged on the square telescopic shaft 73, and the sleeve block 81 is fixedly connected to the square telescopic shaft 73. The rotation of the square telescopic shaft 73 drives the sleeve block 81 to rotate synchronously, and at the same time drives the inner screw barrel 82 to descend. The outer side of the sleeve block 81 is threadedly provided with an inner screw barrel 82, and the inner screw barrel 82 is slidably engaged with the cross support frame 74. A thread is provided on the outer side of the inner screw barrel 82, and the thread is close to the cross support frame 74, and a threaded relationship is formed between the thread and the outer screw barrel 83. The outer side of the inner screw barrel 82 is threadedly provided with an outer screw barrel 83, and the distance of the inner thread of the outer screw barrel 83 is less than the overall length of the outer screw barrel 83. A second extension rod 84 is arranged in an array at one end of the outer screw barrel 83 away from the cross support frame 74, and the other end of the second extension rod 84 is fixedly connected to the support fixing plate 21.

[0072] The outer screw barrel 83 is symmetrically provided with an elastic extension rod 831 at one end away from the cross support frame 74. The inner rod extension end of the elastic extension rod 831 is normally inserted into the through arc groove 821 provided on the inner screw barrel 82, so that when the square telescopic shaft 73 rotates, the sleeve block 81 sleeved on the square telescopic shaft 73 drives the inner screw barrel 82 to descend, so that the sampling barrel 41 engaged with the sliding on one side of the inner screw barrel 82 is moved closer to the soil;

[0073] The inner screw barrel 82 is symmetrically provided with through arc grooves 821, and an annular plate 822 is movably provided inside the inner screw barrel 82, and the annular plate 822 and the inner screw barrel 82 are engaged and slidably engaged, and an annular plate 823 is movably provided on the side of the annular plate 822 close to the motor 71, and the annular plate 823 has an arc-shaped chamfer on the side away from the annular plate 822, which is used to contact the elastic extension rod 831 after the annular plate 823 moves, so that the elastic extension rod 831 contracts, and finally cooperates with the rotation of the inner screw barrel 82 to make the elastic extension rod 831 disengage from the through arc groove 821, so that the inner screw barrel 82 can rotate;

[0074] A matching push plate 824 is arranged in an array on one side of the annular plate 823 close to the annular plate 822. The matching push plate 824 and the annular plate 823 are connected by a connecting rod. When the matching push plate 824 contacts the fitting block 81, the matching push plate 824 will drive the annular plate 823 to rise, thereby contacting and squeezing the elastic extension rod 831. A third spring 825 is sleeved on the matching push plate 824, and the third spring 825 is used to reset the annular plate 823.

[0075] During use, when the rotating shaft 72 and the square telescopic shaft 73 rotate synchronously, the cross support frame 74 transmits power to the sampling tube 41 under the rotation of the square telescopic shaft 73, and at the same time, the square telescopic shaft 73 drives the sleeve block 81 to rotate synchronously, driving the inner screw barrel 82 screwed thereto to descend. During the entire descending process, the elastic extension rod 831 on the outer screw barrel 83 forms a card connection with the through arc groove 821 provided on the inner screw barrel 82, so that the inner screw barrel 82 does not rotate. When the screw barrel 82 descends and the matching push plate 824 contacts the sleeve block 81, the matching push plate 824 will drive the annular abutment plate 823 to move, thereby contracting the elastic extension rod 831. At the same time, the sleeve block 81 moves to the final position and drives the inner screw barrel 82 to rotate, so that the elastic extension rod 831 and the inner screw barrel 82 are disengaged from the clamping relationship, and the inner screw barrel 82 is extended from the inside of the outer screw barrel 83 through the provided thread, completing the entire extension process, so that the sampling tube 41 is completely immersed in the soil, completing the entire extension process.

[0076] The remaining structures are the same as those of embodiments 1 and 2.

[0077] Example 4

[0078] See also Figures 1 to 4 , which is the fourth embodiment of the present invention, and this embodiment provides: a geographic information collection and mapping device and a mapping method, comprising the following steps,

[0079] S1, first, the motor 71 drives the rotating shaft 72 and the square telescopic shaft 73 to rotate, and the sleeve block 81 provided on the square telescopic shaft 73 drives the inner screw barrel 82 and the outer screw barrel 83 to descend synchronously, and the sampling tube 41 drives the lifting ring plate 52 to descend as a whole through the engagement between the annular groove 411 provided and the connecting engaging plate 63, so that the piercing plate 53 provided on the lifting ring plate 52 is separated from the contact between the protective shell 51, and the piercing plate 53 can be opened under the action of the telescopic spherical rod 56 and the movable block 57;

[0080] S2, then, under the movement of the sampling tube 41, the piercing plate 53 is driven to penetrate into the soil to stabilize the entire moving base 1. After the rebound torsion plate 541 on the L-shaped support plate 54 contacts, the lifting ring plate 52 is completely released from the engagement with the sampling tube 41, so that it stays at the current position and does not continue to descend;

[0081] S3, at the same time, the square telescopic shaft 73 driven by the motor 71 will drive the inner screw barrel 82 and the outer screw barrel 83 to move in sequence under the action of the sleeve block 81, so that the sampling barrel 41 can enter the soil to sample the soil;

[0082] S4, finally the driving motor 71 rotates in the reverse direction to reset the sampling tube 41. At the same time, the sampling tube 41 rises and resets under the action of the connecting clamping plate 63 provided on the annular groove 411 and the lifting ring plate 52, and the piercing plate 53 is changed from the open state to the retracted state, completing the entire sampling process.

[0083] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
