[0052] Embodiment 1:

[0053] The embodiment discloses a plant specimen collection device for performing a continuous collection operation on a plurality of plant specimens formed by punching.

[0054] Ginseng Figures 12 to 17 As shown, the plant sample collection device comprises: a fixing plate 207, a storage device 52 that rotates in close contact with the fixing plate 207, a first driving mechanism 501 and a mounting bracket. The first driving mechanism 501 is fixed to the fixing plate 207 through the mounting bracket, a plurality of receiving holes 525-528 are formed on the side of the storage device 52 facing the fixing plate 207, the fixing plate 207 is provided with a forming hole 201 that matches the receiving holes 525-528, and the storage device 52 is driven by the first driving mechanism 501 to rotate and form a posture in which at least one receiving hole 525-528 is aligned with the forming hole 201. The first driving mechanism 501 can be a stepping motor or a servo motor or any other power device that can drive the storage device 52 to rotate, and is preferably a stepping motor or a servo motor, so that the rotation angle of the storage device 52 each time can be accurately controlled through the first main shaft 521, so that the receiving holes 525-528 can accurately align with the forming hole 201.

[0055] The receiving holes 525-528 are used to receive the plant samples formed by punching. A plurality of receiving holes 525-528 arranged in a ring are formed on the side of the storage device 52 facing the fixed plate 207. The storage device 52 rotates under the drive of the first driving mechanism 501 and sequentially aligns the receiving holes 525 (or receiving holes 526 or receiving holes 527 or receiving holes 528) with the forming holes 201. The side of the storage device 52 where the receiving holes 525-528 are formed is kept parallel to the back of the fixed plate 207. The multiple receiving holes 525-528 arranged in a ring can simultaneously store multiple plant samples after the plant leaves of plants in a wide range are punched, thereby realizing the operation of the plant sample collection device to continuously and multiple times collect plant samples.

[0056] Ginseng Figures 5 to 9 As shown, the storage device 52 includes: a first main shaft 521 driven by a first driving mechanism 501, a mounting seat 522 formed at the end of the first main shaft 521, and a storage block 523 partially embedded in the mounting seat 522 and received by the mounting seat 522. A receiving hole is formed on the side of the storage block 523 facing the fixed plate 207, and barbs 5251 are formed on the inner wall surface of the receiving holes 525-528. The barbs 5251 ensure that the circular plant samples formed by punching are effectively retained in the receiving holes 525-528, so as to prevent the cutting knife 406 formed at the end of the punching knife 403 from being brought out of the receiving holes 525-528 when the punching knife 403 is retracted along the guide seat 404. It should be noted that the storage block 523 (or storage block 523a) in this embodiment is Fig.12 The air holes 5250 formed in the embodiment may be omitted.

[0057] The barbs 5251 slightly protrude radially inward from the inner annular wall of each receiving hole 525-528, and multiple circles of barbs 5251 are arranged along the depth direction of each receiving hole. The barbs 5251 are bent toward the depth direction of the receiving hole. The barbs 5251 can be convex teeth separated in an annular shape, or convex rings arranged continuously in an annular shape, or convex teeth / convex rings arranged in a spiral shape on the inner wall surface of the receiving hole. The inner diameter enclosed by the barbs 5251 is greater than or equal to the outer diameter of the cutter 406 to prevent the cutter 406 from colliding with the barbs 5251 when being inserted into or pulled out of the receiving holes 525-528. At the same time, when the cutter 406 is inserted into or pulled out of the receiving holes, it keeps coaxial movement with each receiving hole 525-528 along its depth direction, the position of the receiving holes 525-528 remains stationary, and the cutter 406 and the receiving holes 525-528 are inserted or pulled out. The bottoms of the receiving holes 525 to 528 are all provided with air holes 5250, so as to communicate with the first suction hole 5227 through the air holes 5250. In this embodiment, the number of the receiving holes is four, and they are specifically Figure 5The receiving holes 525-528 are formed in the same storage block 523; wherein, the receiving holes 525-526 are formed in the same storage block 523, and the receiving holes 527-528 are formed in the same storage block 523. The opening direction of the four receiving holes is set toward the back side of the fixing plate 207 (i.e., the adsorption surface 5220 of the mounting seat 522 in the storage device 52). The storage block 523 is formed with a handle 5231, so that the storage block 523 can be detachably placed in or taken out by the handle 5231. Figure 6 The middle mounting seat 522 forms a receiving cavity 5220 a and a receiving cavity 5220 b which are symmetrically arranged relative to the positioning post 5222 .

[0058] Combination Figures 5 to 9 As shown, the mounting seat 522 is an oblate cylinder and connected to the first main shaft 521. Two pairs of blind positioning holes 5245 are provided on the circular side of the mounting seat 522 and are symmetrically arranged relative to the first main shaft 521. The mounting seat 522 is located at the bottom of the circular ring of the receiving cavity 5220a and the receiving cavity 5220b and has a first suction hole 5227. Figure 8 From the perspective shown, the storage block 523 is inserted into the receiving cavity 5220a and the receiving cavity 5220b horizontally from left to right, thereby realizing the detachable installation and replacement of the mounting seat 522. After the two mounting seats 522 are inserted into the receiving cavity 5220a and the receiving cavity 5220b horizontally, the side of the storage block 523 facing the fixing plate 207 is flush with the side of the mounting seat 522 facing the fixing plate 207.

[0059] In this embodiment, the storage device 52 elastically holds the storage block 523 by four springs 524. The storage block 523 forms two symmetrically arranged protrusions 5232, and the springs 524 form a retaining groove 5241 for retaining the protrusions 5232. The side of the storage block 523 forms a straight end surface 5234, and the straight end surface 5234 is connected to the storage block 5233. Figure 6 The two parallel inner side surfaces 5246 of the middle receiving cavity 5220a fit together to improve the convenience of disassembly and assembly of the storage block 523 and further improve the efficiency of sampling.

[0060] The protrusion 5232 forms an inclined surface 5233 that shrinks inward. When the storage block 523 is inserted into the receiving cavity 5220a laterally, the protrusion 5232 is fastened by the fastening groove 5241 to fix the storage block 523. The bolt 5244 penetrates the spring sheet 524 and is screwed into the positioning blind hole 5245 to fix one end of the spring sheet 524. The guide end 5242 of the spring sheet 524 used to fix the same storage block 523 is opened laterally to improve the tolerance rate of disassembly and assembly, so that the storage block 523 can be inserted into the receiving cavity 5220a laterally through the guide ends 5242 of the two spring sheets 524, so as to reliably fix the protrusion 5232 of the storage block 523 through the two spring sheets 524 and ensure that the guide end 524 is partially attached to the inclined surface 5233. In this way, the storage block 523 can be movably inserted into or pulled out of the receiving cavity 5220a.

[0061] The mounting seat 522 faces the first main axis 521 to form an adsorption surface 5220. The flange 530 is movably embedded in the adsorption surface 5220 and protrudes from the adsorption surface, and a suction channel is established between the flange 530 and the first suction hole 5227. The protruding direction of the flange 530 is the direction facing the storage device 52.

[0062] The first suction hole 5227 penetrates the mounting seat 522 in a direction parallel to the first main axis 521, and forms four recessed portions 5239 for accommodating the flange 530 on the adsorption surface 5220 of the mounting seat 522. A straight cylindrical through hole 5303 (see FIG. 5 ) may be formed at the center of the flange 530. Fig.10 ) or step hole 5260 or step hole 5270. The step hole 5260 or the step hole 5270 is connected to the first suction hole 5227. The flange 530 is embedded in the recessed portion 5239 in a magnetic adsorption manner, and is connected to the first suction hole 5227 through the through hole 5303 (or the step hole 5260 or the step hole 5270) of the flange 530, thereby establishing a suction channel between the flange 530 and the first suction hole 5227.

[0063] The flange 530 includes a magnetic ring 5301 and an elastic ring 5302 embedded in the recessed portions 5239, and ensures that the elastic ring 5302 can protrude from the adsorption surface 5220 of the mounting seat 522 when the flange 530 is embedded in the four recessed portions 5239. Further, the magnetic ring 5301 can attract each other with the ferromagnetic mounting seat 522. The annular surface formed by the elastic ring 5302 protruding from the adsorption surface 5220 is flush with the anastomotic end 2371, or the anastomotic end 2371 and the annular surface formed by the elastic ring 5302 protruding from the adsorption surface 5220 form a certain gap, such as a gap of 1 to 2 mm, to ensure that the suction airflow formed by the suction tube 237 can be transmitted to the receiving holes 525 to 528 through the first suction hole 5227 and the air hole 5250, respectively, so as to form a negative pressure area in the receiving holes 525 to 528 for adsorbing the punched plant samples. This technical solution is not only conducive to the effective separation of the plant samples formed by punching from the cutter 406 , but also more conducive to the orderly stacking of the plant samples in the receiving holes 525 - 528 .

[0064] In this embodiment, the hanging plate 301 is preferably kept horizontally arranged and a positioning block 307 for fixing the suction tube 237 is arranged at one side edge close to the first driving mechanism 501. The suction tube 237 can be connected to the negative pressure generating device through a rigid / flexible pipeline. A flange 530 is arranged which is embedded in the adsorption surface 5227 and partially protrudes out of the adsorption surface 5220. The flange 530 has a through hole 5303. The anastomotic end 2371 forms a gap with the adsorption surface 5220. During the rotation of the storage device 52, the anastomotic end 2371 sequentially forms a posture aligned with the through hole 5303 of the flange 530.

[0065] Ginseng Figure 8 As shown, as a reasonable deformation, the adsorption surface 5220 of the mounting seat 522 forming the first suction hole 5227 can directly form a flange 530a which is connected to the first suction hole 5227 and has a step hole 5260, and the anastomotic end 2371 forms at least a certain gap with the adsorption surface 5220, and the anastomotic end 2371 and the flange 530a do not interfere with each other during the rotation of the storage device 52.

[0066] Ginseng Fig. 9 As shown, as a further variation of this embodiment, the flange 530 (or flange 530a) can be omitted, and four step holes 5270 connected to the first suction hole 5227 can be directly opened on the adsorption surface 5220. By adjusting the aperture of the step hole 5260 of the flange 530a, the adsorption force of the plant sample in the receiving holes 525-528 can be flexibly adjusted. Of course, Figure 8 The stepped hole 5260 of the middle flange 530a can also be flexibly adjusted.

[0067] At the same time, Fig.11As shown, in the present embodiment, each storage block 523 forms two steps 5236, and the receiving cavity 5220a and the receiving cavity 5220b of the mounting seat 523 are laterally protruded from the inner side close to the positioning column 5222 and the stopper 5228 and the stopper 5229 that limit the displacement of the step along the longitudinal extension direction of the first main axis 521. When the storage block 523 is laterally inserted into the receiving cavity 5220a (or the receiving cavity 5220b), the stopper 5228 (or the stopper 5229) further prevents the storage block 523 from being disengaged from the receiving cavity 5220a (or the receiving cavity 5220b), thereby further improving the reliability of the movable assembly of the storage block 523 and the mounting seat 522. The storage block 523 is recessed to form a semicircular recessed portion 5235 that fits the positioning column 5222, thereby further limiting the lateral movement of the storage block 523. In each embodiment of the present application, the lateral direction in "lateral movement" refers to the direction parallel to Figure 1 The extension direction of the central axis E or axis C.

[0068] Ginseng Figure 5 , Figure 6 , Fig.11 and Fig.12 As shown, the mounting seat 522 is provided with a first suction hole 5227 that is connected to the receiving holes 525-528 and penetrates the mounting seat 522. Specifically, the mounting seat 522 forms four first suction holes 7227. The plant sample collection device further includes: a suction pipe 237 that forms a suction airflow, and a mating end 2371 is configured at the end of the suction pipe 237. During the rotation of the storage device 52, the mating end 2371 forms a posture that is aligned with and fits the first suction hole 5227, so that the suction airflow formed by the suction pipe 237 connecting the negative pressure generating device sucks the air in the absorption holes 525-528 through the mating end 2371, thereby adsorbing and fixing the plant sample at the bottom of the receiving holes 525-528.

[0069] The anastomotic end 2371 and the suction tube 237 form a suction channel (not shown), and the suction tube 237 is preferably a rigid structure. When the storage device 52 is driven by the first driving mechanism 501, the anastomotic end 2371 is aligned with the first suction hole 5227 every time it rotates ninety degrees, so that the suction airflow formed by the anastomotic end 2371 adsorbs the plant samples contained in the receiving holes 525-528. It should be noted that the first driving mechanism 501 drives the storage device 52 to rotate to form the anastomotic end 2371 and the first suction hole 5227. The required rotation angle depends on the number and arrangement of the receiving holes, and the offset position between the central axis of the storage device 52 and the center of the forming hole 201.

[0070] Combination Fig.15As shown, the plant sample collection device also includes: a hanging plate 301 connected to the fixed plate 207, the hanging plate 301 is provided with a first suction portion 333 for forming a suction airflow, the first suction portion 333 is arranged at the intersection where the fixed plate 207 and the hanging plate 301 intersect, the first suction portion 333 forms a suction airflow that fits the extended plane of the fixed plate 207, further, when the hanging plate 301 is placed horizontally, the suction airflow flows upward, and the flow direction of the suction airflow is as shown in FIG. Fig.15 As shown by the arrow G in the middle. The first suction part 333 is composed of a plurality of elongated rectangular holes (or circular holes or holes of any other shape) arranged regularly, and the top of the hanging plate 301 is provided with an interface part 306. The interior of the fixing plate 207 has a hollow channel (not shown), so that the interface part 306 is connected to the first suction part 333 through the hollow channel to establish a suction channel, and the interface part 306 is connected to the negative pressure generating device (not shown) through a pipeline (not shown), so that the negative pressure generating device sucks air through the pipeline, and then the first suction part 333 forms a vacuum. Fig.15 It should be noted that when the posture of the hanging plate 301 can be adjusted, the flow direction of the suction airflow can be adjusted accordingly, and the flow direction of the suction airflow can be controlled according to the growth state of the leaves to improve the applicability of the device. For example, when the leaves of the plant grow upward, the hanging plate 301 can be set horizontally as shown in FIG. Figure 1 As shown, in order to better improve the adsorption effect of plant leaves and the flatness of plant leaves after adsorption and the clamping surface 2070 of the fixed plate 207, when the plant leaves are dense and need to be sampled from the side or bottom, the posture of the hanging plate 301 can be adjusted as needed to ensure the accuracy of leaf picking. Thus, the plant leaves in the plant with random postures are changed from posture 200 to posture 200a to straighten the plant leaves, so that the plant leaves are reliably attached to the clamping surface 2070 of the fixed plate 207, and the clamping surface 2070 and the back of the aforementioned fixed plate 207 are respectively two side surfaces of the plane where the fixed plate 207 is located. The clamping surface 2070 of the fixed plate 207 and the clamping surface 1070 of the rotating plate 107 clamp the plant leaves together.

[0071] Ginseng Fig.13 As shown, three ears 2071 are set at the top edge of the fixing plate 207 connected to the hanging plate 301, and each ear 2071 is provided with a screw hole 2171. At the same time, three through holes 2271 connected to the hanging plate 301 and having internal threads are also set at the top of the fixing plate 207. Figure 1 As shown, the top of the hanging plate 301 is vertically extended through the hanging plate 301 by bolts and then screwed and fixed to the screw holes 2171, so that the fixing plate 207 and the hanging plate 301 are vertically and reliably assembled and connected.

[0072] Combination Fig.13 , Fig.14 and Fig.15As shown, in this embodiment, the fixing plate 207 is provided with at least one circle of second suction parts for forming suction airflow relative to the side where the storage device 52 is provided, and the second suction parts are formed on the radial outer side of the forming hole 201. The fixing plate 207 is provided with an interface part 227 connected with the second suction part on the side where the storage device 52 is provided. The suction airflow formed by the second suction part is symmetrically arranged relative to the forming hole 201, so that the suction airflow formed by the second suction part can evenly and symmetrically adsorb the plant leaves, so that the plant leaves can more completely cover the forming hole 201, thereby ensuring that the punched plant sample can match the inner contour of the forming hole 201, and avoiding the punched plant leaves from being incomplete and incomplete. Usually, subsequent precise testing of plant samples, such as NDA testing, pesticide residue testing, plant hormone level testing, etc., requires strict requirements on the amount of plant samples to be tested. Especially in the use scenario of large-scale planting of crops, if the amount of plant samples to be tested by punching cannot meet the set requirements, it will have a serious impact on the subsequent testing process and test results. Therefore, too much or too little testing is not appropriate.

[0073] In the embodiment, since the storage block 523 can be movably configured, the storage block 523 (storage block 523a) with a different inner diameter can be replaced according to the actual detection requirements of each item to be detected, and the diameter of the punch axis knife 403 can be replaced at the same time, thereby realizing flexible adjustment of the corresponding inspection quantity of the plant samples formed by punching within a certain range to meet the detection requirements of different inspection quantities.

[0074] Ginseng Figure 1 , Fig.13 and Fig.15 As shown, in this embodiment, the second suction part is composed of a plurality of second suction holes arranged in an annular manner and enclosing a forming hole 201, and the fixing plate 207 is provided with at least one circle of airtight ring partially embedded in the fixing plate 207. Specifically, the second suction part is composed of two circles of circular air holes 205 arranged in concentric circles, and the forming hole 201 is located at the center of the second suction part. An outer circle of airtight ring 204 partially embedded in the fixing plate 207 is provided on the radial outer side of the circle of circular air holes 205 located on the outside, a middle circle of airtight ring 203 partially embedded in the fixing plate 207 is provided between the two circles of circular air holes 205, and an inner circle of airtight ring 202 partially embedded in the fixing plate 207 is provided on the radial inner side of the circle of circular air holes 205 located on the inside. The outer circle of airtight ring 204, the middle circle of airtight ring 203 and the inner circle of airtight ring 202 can all be made of elastic materials with good weather resistance such as rubber and silicone. The outer ring 204 , the middle ring 203 , and the inner ring 202 all protrude from the clamping surface 2070 of the fixing plate 207 .

[0075] Combination Figures 13 to 15 , Fig.18As shown, the mounting bracket is detachably connected to the fixing plate 207. Specifically, the mounting bracket includes: a first bracket 503 detachably connected to the fixing plate 207, a second bracket 502 detachably connected to the first bracket 503, a first driving mechanism 501 is fixed by the second bracket 502, the first driving mechanism 501 is provided with a first main shaft 521 continuously extending through the second bracket 502 and the first bracket 503, the storage device 52 rotates in the area 505 enclosed by the first bracket 503 and the fixing plate 207, and the first main shaft 521 is arranged in a non-coaxial relationship with the forming hole 201, that is, the first main shaft 521 is eccentrically arranged on one side of the forming hole 201.

[0076] The first bracket 503 forms a vertical plate 513 vertically arranged with the fixed plate 207, and the vertical plate 513 is horizontally extended to form a mounting plate 5131 that is in surface contact with the fixed plate 207. The mounting plate 5131 has through holes and is screwed and fixed by bolts 5132 that continuously penetrate the mounting plate 5131 and four through holes 2072 of the fixed plate 207, so that the first bracket 503 is reliably assembled with the fixed plate 207. The first bracket 503 and the fixed plate 207 enclose an area 505 for the storage device 52 to rotate. At the same time, the first bracket 503 forms a through hole for the first main shaft 521 to pass through, and a bearing 512 is embedded at the top of the first bracket 503. The first main shaft 521 passes through the bearing so that the first main shaft 521 can rotate smoothly in the first bracket 503.

[0077] The second bracket 502 is fixed to the end of the first bracket 503 by bolts, and the first driving mechanism 501 is fixedly disposed on the second bracket 502, and drives the first main shaft 521 to rotate, so as to drive the storage device 52 to rotate in the area 505. The first driving mechanism 501 is connected to the control device (not shown) through a wire (not shown), so that the control device outputs a control signal (such as a PWM signal) to the first driving device 501, so as to drive the storage device 52 to rotate.

Through the joint action of the first suction part 333 for forming the suction airflow opened by the hanging plate 301 and the second suction part enclosed on the radial outer side of the forming hole 201, the effective punching and sampling operation of the plant leaves in random postures in the plant is achieved, and the quantitative sampling of plant samples is achieved, meeting the subsequent more accurate detection requirements of plant samples. At the same time, through the movable embedded mounting seat 522 and the storage block 523, the plant samples can be easily taken out, which has the advantage of being easy to use.

[0080] Embodiment 2:

[0081] As a reasonable variation of the plant sample collecting device shown in the first embodiment, this embodiment further discloses a plant sample collecting device.

[0082] Combination Figures 19 to 22 As shown, the main difference between the plant sample collection device disclosed in this embodiment and the plant sample collection device disclosed in the first embodiment is that, in this embodiment, the storage block 523a and the mounting seat 522a are reliably fixed to each other by means of bolts 5238 that continuously penetrate the mounting seat 522a and the storage block 523a from the adsorption surface 5220 of the mounting seat 522a along the longitudinal extension direction parallel to the first main axis 521.

The side of the storage block 523a forms a straight end face 5237, and the straight end face 5237 is aligned with the storage block 523a. Figure 6 The two parallel inner sides 5246 of the middle receiving cavity 5220a are fitted together. The two storage blocks 523a are fixed by two bolts 5238 respectively.

The sampling device comprises: a rotating plate 107 that clamps plant leaves together with a fixed plate 207, a punching device 40 installed on one side of the rotating plate 107, a second driving mechanism 10 that drives the punching device 40 to punch out plant samples, and a third driving mechanism that is hinged to the plant sample collecting device and drives the rotating plate 107 to open or close. Fig.15 As shown, hinge seats 307 are respectively provided on both sides of the fixed plate 207 near the first suction portion 333, and the hinge seats 307 are connected to the hanging plate 301 by bolts 327. The hinge seats 307 form a tongue plate 317. The top of the rotating plate 107 forms a hinge portion 2074 for accommodating the tongue plate 317. The hinge portion 2074 and the tongue plate 317 are horizontally provided with a pin shaft 3171, so that the rotating plate 107 and the fixed plate 207 are connected along the Fig.16 The rotating plate 107 rotates in the direction indicated by the central axis E. Usually, the fixed plate 207 maintains a relatively fixed position, and the rotating plate 107 rotates around the axis E relative to the fixed plate 207 under the drive of the third driving mechanism.

[0087] Ginseng Figure 1 and Figure 2 As shown, in this embodiment, the hanging plate 301 is along Figure 1 A contraction portion is formed in the vertical projection direction under the viewing angle, and a cantilever 302 is arranged at the end of the contraction portion. A mounting plate 3021 is arranged horizontally on the cantilever 302, and a bolt 3022 vertically penetrates the mounting plate 3021 and the contraction portion to reliably connect one end of the cantilever 302 with the hanging plate 301.

[0088] A retractable third driving mechanism is arranged between the cantilever 302 and the rotating plate 107. The rotating plate 107 is provided with a hinged portion 305, and the third driving mechanism includes a driving mechanism such as an electric push rod, a linear motor or an electric cylinder that can realize telescopic movement in a linear direction. The third driving mechanism includes: a base 303 hinged to the cantilever 302, a linear motion assembly 304 assembled in a straight line with the base 303, and a telescopic rod 3041 received by the linear motion assembly 304 and performing telescopic movement in the linear motion assembly 304 in a linear direction, and a tongue plate embedded in the hinged portion 305 is arranged at the end of the telescopic rod 3041, and the hinged portion 305 and the tongue plate are horizontally inserted through a pin shaft 3051 to realize the hinged connection between the end of the telescopic rod 3041 and the rotating plate 107.

[0089] The end of the telescopic rod 3041 is provided with a tongue plate inserted into the hinge part 305 and the tongue plate at the end of the telescopic rod 3041 is horizontally penetrated through the hinge part 305 and the end of the telescopic rod 3041 through the pin shaft 3051, so that the telescopic rod 3041 is hinged to the rotating plate 107 through the hinge part 305, and the telescopic rod 3041 is hinged to the rotating plate 107 along the hinge part 305. Figure 1The other end of the cantilever 302 away from the mounting plate 3021 is provided with a hinge seat 3023, the base 303 is provided on the cylinder 3031 hinged to the hinge seat 3023, and a pin 3024 is used to horizontally penetrate the hinge seat 3023 and the cylinder 3031, so that the base 303 and the cantilever 302 are connected along the Figure 1 The central axis A rotates. Thus, under the drive of the third driving mechanism, the rotating plate 107 is driven to rotate along the axis E, so as to drive the rotating plate 107 to rotate relative to the fixed plate 207, so as to drive the rotating plate 107 to open or close; when the rotating plate 107 and the fixed plate 207 are closed, the plant leaves that have been adsorbed on the clamping surface 2070 of the fixed plate 207 and are in the posture 200a are clamped (see Figure 1 As shown), the punching device 40 performs a punching operation on the plant leaves to form a plant specimen; when the rotating plate 107 and the fixed plate 207 are opened (see Figure 2 As shown), the plant sample sampling device is carried by an operating machine such as an unmanned aerial vehicle and moved to the area where the plant leaves of the plant are located, and the aforementioned closing operation is performed again.

[0090] The second driving mechanism 10 includes: a stepper motor 101, a second main shaft 106 coaxially arranged with the stepper motor 101 and driven by the stepper motor 101, and a cam 104 sleeved on the second main shaft 106. Spacers 1061 for clamping the cam are arranged on both lateral sides of the cam 104. The cam 109 is fixedly connected to the second main shaft 106. When the second main shaft 106 rotates one circle, the cam 104 applies a force perpendicular to the rotating plate 107 to the push seat 402 of the punching device 40, thereby achieving the purpose of driving the punching device 40 to punch out the plant sample.

[0091] The rotating plate 107 of the plant sample sampling device further includes a motor base 1011, a bearing base 1012 and a bearing base 1013 perpendicular to the rotating plate 107. The second main shaft 106 horizontally and continuously penetrates the bearing seat 105 fixed at the end of the bearing base 1012 and the bearing seat 105 fixed at the end of the bearing base 1013. Each bearing seat has a built-in bearing 109. The inner ring of the bearing 109 is fixed to the bearing seat, and the inner ring of the bearing 109 is fixed to the second main shaft 106. The bearing seat 105 is fixed to the bearing base 1012 (bearing base 1013) by bolts 1101. The top of the motor base 1011 is provided with a mounting plate 102 for fixing the stepper motor 101, and the bolts 1021 horizontally penetrate the mounting plate 102 and screw into the stepper motor 101, so as to fix the stepper motor 101 on one side of the mounting plate 102.

[0092] Ginseng Figure 3 and Figure 4As shown, the punching device 40 comprises: a punching knife 403 with a cutter 406 formed at the end, a push seat 402 arranged at one end of the punching knife 403, a guide seat 404 for accommodating the other end of the punching knife 403, and an elastic component 405 (such as a spring or a damper, etc.) sleeved on the outside of the punching knife 403 and integrally accommodated in the guide seat 404. The guide seat 404 is laterally extended to provide a flange 401 connected to the rotating plate 107. The rotating plate 107 is provided with a punching hole 108 matching the forming hole 201, and the cutter 406 extends through the punching hole 108 to punch the plant leaves clamped by the fixed plate 207 and the rotating plate 107. The diameter of the punching hole 108 is based on the basic condition that the cutter 406 can be extended or retracted, and the outer diameter of the cutter 406 is adapted to the diameter of the forming hole 201, and preferably the outer diameter of the cutter 406 is slightly smaller than the diameter of the forming hole 201.

[0093] The push seat 402 forms a cylinder 4021 that partially accommodates the punching knife 403. The bolt 408 horizontally penetrates the through hole 4071 opened in the cylinder 4021 and horizontally penetrates the punching knife 403. The nut 407 is screwed and fixed with the bolt 408 to fix the punching knife 403 and the cylinder 4021, and reliably fix the end 4031 of the punching knife 403 in the cylinder 4021. The other end of the punching knife 403 forms a cutter 406, and the shape of the cutter 406 is consistent with the contour of the plant sample finally formed by punching. The punching knife 403 is radially outwardly provided with a retaining ring 4032. The guide seat 404 is hollow inside and has a cylindrical hollow cavity 4040, and a diameter reduction portion 4041 is formed at one end away from the cutter 406. The other end of the guide seat 404 is open, and the cutter 406 extends out or retracts from the open. A flange 401 connected to the rotating plate 107 is horizontally extended from the open portion of the guide seat 404. Four through holes 4011 are arranged around the flange 401, and bolts are vertically inserted into the through holes 4011 and screwed to the through holes with internal threads preset on the rotating plate 107 to vertically fix the guide seat 404 on the rotating plate 107. The flange 401 and the rotating plate 107 fit each other.

[0094] When the cam 104 rotates under the control of the second driving mechanism 10 to apply a force perpendicular to the rotating plate 107 to the push seat 402, the retaining ring 4032 and the rotating plate 107 jointly compress the elastic component 405, thereby integrally driving the push seat 402 and the axis punching knife 403 to extend out of the punching hole 108 in a posture perpendicular to the rotating plate 107, and punching the plant leaves clamped by the rotating plate 107 and the fixed plate 207 through the cutter 406 to form a plant sample. When the cam 104 does not apply a force perpendicular to the rotating plate 107 to the push seat 402, the push seat 402 and the axis punching knife 403 are reset under the action of the elastic component 405, thereby retracting the axis punching knife 403 from the punching hole 108. In the retracted state, the cutter 406 at least does not protrude from the clamping surface 1070 of the rotating plate 107 for clamping the plant leaves.
