By detecting indicators such as the composition, structure, and fertility of slope soil, the stability of the slope and the ecological environment status can be scientifically evaluated, providing a reliable basis for treatment measures such as vegetation restoration and soil erosion prevention. Currently, common soil sampling methods mostly use simple tools for manual excavation or traditional sampling instruments. These methods meet the basic sampling needs to a certain extent, but there are still many areas to be improved.

[0003] Existing sampling devices for ecological slope treatment have many defects in practical applications. On the one hand, it is difficult to effectively avoid sample contamination. During the sampling process, plant debris, insect remains, etc. around the sampling point cannot be processed, and these sundries mixed into the sample will affect the accuracy of the detection results; On the other hand, the sampling operation is not convenient and efficient enough.

[0018] To make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0019] Example 1, as Figure 1 and Figure 2 shown, a sampling device for ecological slope treatment includes a handle 1, anti-slip sleeves 2 are symmetrically and fixedly connected to the outer surface of the handle 1, first connecting columns 3 are symmetrically and fixedly connected to the lower part of the outer surface of the handle 1, a sampling connection structure 6 is fixedly connected to the ends of the two first connecting columns 3 away from the handle 1, a sampling structure 5 is arranged on the inner surface of the sampling connection structure 6, and a pedal structure 4 fixedly connected to the sampling connection structure 6 is arranged on the outer surfaces of the two first connecting columns 3 together; the sampling structure 5 includes a sampling cylinder 52 arranged on the inner surface of the sampling connection structure 6, a top cover 51 is arranged on the upper part of the inner surface of the sampling cylinder 52, and a bottom cover 53 is arranged at the lower end of the sampling cylinder 52.

[0020] Further, to send the sampling structure 5 into the soil to achieve soil sampling, refer to Figure 3 , the pedal structure 4 includes a first slider 42 slidably connected to the outer surfaces of the two first connecting columns 3, pedals 41 are symmetrically and fixedly connected to the outer surface of the first slider 42, and a second connecting column 43 fixedly connected to the sampling connection structure 6 is fixedly connected to the lower end of the first slider 42.

[0021] Step on the pedal 41 to drive the first slider 42 to slide downward, and thereby use the second connecting column 43 to transmit the downward pressure to the sampling connection structure 6, so as to drive the connecting component 64 to move downward. At the same time, if the sampling connection structure 6 and the sampling structure 5 cannot be taken out of the soil layer, at this time, step on the sampling connection structure 6 and pull up the pedal 41 to lift the top cover 51 out of the soil layer.

[0022] Further, to fix the sampling cylinder 52 and drive the sampling cylinder 52 to take soil, refer to Figure 3 The sampling connection structure 6 includes a housing 61 fixedly connected to the lower end of the anti-slip sleeve 2. The upper part of the inner surface of the housing 61 is fixedly connected with a partition 62. The inner surface of the housing 61 is slidably connected with a connecting component 64. The second connecting column 43 penetrates through the housing 61 and the partition 62 and extends to the upper end of the connecting component 64 and is fixedly connected with the connecting component 64.

[0023] The housing 61 is connected to the first connecting column 3 and is used for support during the soil sampling process. Further, the partition 62 installed inside it is a structure for switching the locking and unlocking actions of the connecting component 64 and is used to provide an installation site for the air pump 63. The connecting component 64 is used to connect the sampling cylinder 52, buckle and lock the sampling cylinder 52 inside the connecting component 64, and thereby drive the sampling cylinder 52 to move up and down following the movement of the second connecting column 43.

[0024] During the operation of this embodiment, first install the sampling cylinder 52 with the top cover 51 buckled in the sampling connection structure 6. Hold the handle 1 through the anti-slip sleeve 2 and align the sampling connection structure 6 with the sampling point so that the bottom of the sampling connection structure 6 touches the soil to be sampled. Through the cooperation of the sampling connection structure 6 and the sampling structure 5, the vegetation, insects or other debris around the sampling cylinder 52 are processed to avoid the broken insect remains or leaves in the sample from contaminating the sample and the final test results; step on the pedal 41 to cause the first slider 42 and the second connecting column 43 to descend, driving the connecting component 64 to move downward, and push the sampling cylinder 52 into the soil layer to be sampled. Twist the sampling connection structure 6 through the handle 1 to separate the soil sample in the sampling cylinder 52 from the soil layer, and thereby separate the sampling cylinder 52 with the sample from the soil layer. The quick disassembly is realized through the cooperation of the connecting component 64 and the sampling cylinder 52. Further, the cooperation of the bottom cover 53 and the sampling cylinder 52 is used to seal the sample and reduce the loss of the effective components in the sample.

[0025] Example 2: On the basis of Example 1, this example uses the cooperation between the top cover 51 provided on the upper side of the sampling cylinder 52 and the connection assembly 64 to continuously supply air flow to the second connecting pipe 522 through the first connecting pipe 512, and uses the function of the Y-shaped pipe 523 to cause the air flow to be shunted and then respectively transported to the inner and outer surfaces of the sampling cylinder 52. By blowing the surface layer of the slope soil, the weeds or insect remains around the sampling point are separated from the sampling area, so as to avoid sample contamination and affect the final test results caused by breaking the leaves or crushing the insects during the sampling process.

[0026] Specifically, to achieve the sealing of the sampling cylinder 52 and cooperate with the bottom cover 53 to completely take out the sample after being transported to the detection structure, refer to Figure 4 , a number of conical grooves 513 corresponding to the positions of the conical connectors 6443 are annularly distributed at the upper end of the top cover 51. The bottom walls of the inner surfaces of the number of conical grooves 513 are all provided with the first connecting pipes 512 communicating with the side wall of the top cover 51. The upper end of the top cover 51 is symmetrically provided with notches 511, and the outer surface of the top cover 51 and the inner wall of the sampling cylinder 52 are buckled through the buckling grooves.

[0027] It should be particularly noted that a magnetic sheet is pasted on the upper end of the top cover 51, and when the top cover 51 is inside the connection assembly 64, it will be adsorbed to the connection assembly 64.

[0028] The notches 511 on the top cover 51 are used to pinch and rotate the top cover 51 to separate it from the sampling cylinder 52. The connection method between the top cover 51 and the sampling cylinder 52 is a conventional rotary snap design for closing the inner cavity of the sampling cylinder 52. At the same time, a ventilation hole is provided in the upper part of the top cover 51 to exhaust air during the sampling process to avoid too high air pressure inside the top cover 51; At the same time, the conical grooves 513 provided above the top cover 51 are docked with the second sliders 644, which can continuously supply air to the sampling cylinder 52, thereby realizing the separation of the weeds or insect remains around the sampling point from the sampling area, and further realizing the control of the sampling accuracy and sample accuracy, and avoiding sample contamination and affecting the final test results caused by breaking the leaves or crushing the insects during the sampling process.

[0029] Furthermore, to achieve the demarcation treatment of the weeds or insect remains around the sampling point, refer to Figure 4 , an annular groove 521 adapted to the third slider 6433 is provided on the upper part of the outer surface of the sampling cylinder 52. A number of teeth 524 are fixedly connected in an annular distribution at the lower end of the sampling cylinder 52. A number of second connecting pipes 522 are annularly distributed and opened in the inner cavity of the sampling cylinder 52. The lower ends of the number of second connecting pipes 522 are all provided with Y-shaped pipes 523 communicating with the inner and outer surfaces of the annular groove 521. Check valves 525 are fixedly installed on the inner surfaces of the two output ports on both sides of the Y-shaped pipe 523. When the top cover 51 is on the inner surface of the sampling cylinder 52, the second connecting pipe 522 is communicated with the first connecting pipe 512, and the lower end of the sampling cylinder 52 is closely attached to the upper end of the bottom cover 53.

[0030] The annular groove 521 is used to cooperate with the connecting component 64 to lock and release the sampling tube 52. The connecting tube 2 522 opened in the inner cavity of the sampling tube 52 is connected to the connecting tube 1 512. The airflow is transported to the annular groove 521 through the connecting tube 1 512 and distributed to the inner and outer surfaces of the sampling tube 52 through the Y-shaped tube 523. At this time, the weeds, leaves, and insect debris can be blown away by the blowing of the airflow before the teeth 524 come into contact with the ground, so that a boundary appears between the sampling position and other positions, thereby ensuring the sample accuracy and reducing the detection error.

[0031] Embodiment 3: Based on embodiment 2, this embodiment further locks and releases the sampling tube 52 during the sampling process through the cooperation of the connecting component 64 and the partition 62 arranged inside the shell 61, and further locks the annular groove 521 in the sampling tube 52 during the sampling process through the action of the movable plate 642 and the locking piece 643 in cooperation with the slider 2 644, thereby driving the annular groove 521 and the slider 2 644 to move downward synchronously under the action of the connecting column 2 43 to sample the slope soil layer; at the same time, through the cooperation of the locking piece 643 and the upper partition 62, after the connecting component 64 is completely reset, the slider 3 6433 is prompted to leave the inner surface of the annular groove 521, thereby canceling the lock on the sampling tube 52, making it convenient for the operator to take out the sampling tube 52 from the connecting component 64, thereby improving convenience and practicality.

[0032] Specifically, to achieve the locking and unlocking of the sampling tube 52, refer to Figure 5 and Figure 6 The connecting assembly 64 includes a movable plate 642 fixedly connected to the lower end of the connecting column 43, and the upper end of the movable plate 642 and the lower end of the partition 62 are provided with a tension spring 641 fixedly connected, and the lower part of the movable plate 642 is provided with a slider 644 slidingly connected to the inner surface of the outer shell 61, and a plurality of locking pieces 643 are arranged in a ring-shaped distribution on the upper end and the inner surface of the slider 644, and the sampling tube 52 is arranged on the inner surface of the slider 644, and the upper end of the top cover 51 is in close contact with the top wall of the inner surface of the slider 644.

[0033] The magnetic patch on the upper side of the top cover 51 can be adsorbed together with the top wall of the inner surface of the second slider 644. The adsorption force of the magnetic patch can keep the connection component 64 and the sampling tube 52 relatively stable regardless of whether the sampling tube 52 is empty or fully loaded. When sampling is required, the second slider 644 will be locked with the annular groove 521 by the action of the locking member 643, thereby preventing the sampling tube 52 from being separated from the second slider 644 during the downward or upward movement of the sampling tube 52; When the second slider 644 resets to the uppermost position, the locking member 643 resets. At this time, the second slider 644 and the sampling cylinder 52 are only adsorbed together by magnetic patches. At this time, the sampling cylinder 52 is sealed by the bottom cover 53, and the sampling cylinder 52 is taken out of the second slider 644, and a new sampling structure 5 is placed to perform sampling again, thereby realizing continuous operation.

[0034] Further, to lock and release the annular groove 521, refer to Figure 7 and Figure 8 , the locking member 643 includes a connecting rod 6434 fixedly connected to the upper end of the second slider 644. The upper end of the connecting rod 6434 penetrates through the lower end of the movable plate 642 and extends to the upper end of the movable plate 642. Limiting blocks 6435 are symmetrically and fixedly connected to the outer surface of the connecting rod 6434 along the movable plate 642. Cross grooves 6430 are opened at the upper ends of the two limiting blocks 6435. Cross blocks 6436 are slidably connected to the inner surfaces of the two cross grooves 6430. The two cross blocks 6436 are fixedly connected by a cylinder. A first hydraulic cavity 6437 is opened at the lower end of the connecting rod 6434. A piston rod 6439 fixedly connected to the lower end of the lower cross block 6436 is slidably connected to the inner surface of the first hydraulic cavity 6437. The depth of the cross groove 6430 is twice that of the cross block 6436. The upper cross block 6436 is a magnetic block.

[0035] The locking member 643 further includes a second hydraulic cavity 6438 opened at the upper end of the second slider 644 and communicating with a plurality of first hydraulic cavities 6437. A plurality of sliding grooves 6432 are annularly distributed on the inner surface of the second slider 644. Sliders 6433 are slidably connected to the inner surfaces of the plurality of sliding grooves 6432. A plurality of connecting pipes 6431 communicating with the adjacent sliding grooves 6432 are annularly distributed on the bottom wall of the inner surface of the second hydraulic cavity 6438.

[0036] When the movable plate 642 moves downward under the action of the second connecting column 43, the lower cross block 6436 will be pressed into the corresponding cross groove 6430. Synchronously, the upper cross block 6436 will enter the lower half of the upper cross groove 6430. At this time, the piston rod 6439 moves downward, and the hydraulic oil in the first hydraulic cavity 6437 is relayed through the second hydraulic cavity 6438 and pressed into the connecting pipes 6431, and then is transported to the sliding grooves 6432 through the connecting pipes 6431. The expanded hydraulic oil in the sliding grooves 6432 pushes the sliders 6433 to approach the sampling cylinder 52 and enter the annular groove 521. At this time, the sampling cylinder 52 is relatively locked with the second slider 644 through the action of the annular groove 521 and the sliders 6433; During the reset process of the second slider 644 driving the sampling cylinder 52, since the slider 6433 only receives a longitudinal force and will not actively retract into the sliding groove 6432, it is possible to ensure the relative locking of the second slider 644 and the sampling cylinder 52 during the reset process; Further, when the second slider 644 is fully reset, since the movable plate 642 drives the upper limiting block 6435 to rise during the reset process and the cross block 6436 at the bottom is not limited, when the second slider 644 is reset, the upper cross block 6436 will be pulled closer to the partition plate 62 and adsorbed together due to magnetic force. At this time, it will pull the bottom cross block 6436 to move upward synchronously, thereby causing the hydraulic oil in the second hydraulic cavity 6438 to be drawn back into the first hydraulic cavity 6437 by the piston rod 6439. At this time, due to the volume change, the hydraulic oil in the chute 6432 will flow back into the second hydraulic cavity 6438, and cause the third slider 6433 to retract and separate from the annular groove 521.

[0037] Further, to achieve this, refer to Figure 9 , a gas pump 63 is fixedly connected to the upper end of the partition plate 62. The output end of the gas pump 63 is fixedly connected to a first trachea 645. An air distribution pipe 6441 communicating with the first trachea 645 is provided in the inner cavity of the second slider 644. A number of second tracheas 6442 are annularly distributed on the inner surface of the air distribution pipe 6441. A number of conical connectors 6443 communicating with the second tracheas 6442 are fixedly connected to the top wall of the inner surface of the second slider 644 in an annular distribution.

[0038] It should be particularly noted that the above gas pump 63 is a conventional air supply device, and this structure has been widely used in the prior art. In the present invention, it is only used to realize the function of supplying air flow to the top cover 51 and the sampling cylinder 52 through the first trachea 645, and its internal structure, operating principle, wiring and control method will not be elaborated.

[0039] The conical connector 6443 is adapted to the conical groove 513. When the sampling cylinder 52 is placed in the second slider 644, the conical groove 513 is docked and communicated with the conical connector 6443. At this time, the gas path is the gas pump 63, the first trachea 645, the air distribution pipe 6441, the second tracheas 6442, the first connecting pipe 512, the annular groove 521, the Y-shaped pipe 523 and is discharged through the one-way valve 525.

[0040] Embodiment 4. On the basis of Embodiment 3, this embodiment uses the cooperation between the connecting groove 534 opened on the bottom cover 53 and the tooth 524 to receive the tooth 524 into the connecting groove 534, and through the extrusion and friction force of the rubber pad 535 on the tooth 524, the bottom cover 53 and the sampling cylinder 52 are buckled together to realize the sealing of the sampling cylinder 52 and the sample inside it; further, after reaching the detection structure, the top cover 51 is opened through the notch 511, and a columnar rod is inserted through the through hole 532 and pushed upward to push the piston block 531, and the piston block 531 is used to completely push out the sample from the sampling cylinder 52 to improve convenience.

[0041] Specifically, to achieve the sealing of the sample and the convenient removal of the sample, refer to Figure 10, a through hole 532 communicating with its lower end is formed in the bottom wall of the inner surface of the bottom cover 53. A first tension spring 533 is fixedly connected to the bottom wall of the inner surface of the sampling cylinder 52. The upper end of the first tension spring 533 is fixedly connected to a piston block 531 slidably connected to the inner surface of the bottom cover 53. A connection groove 534 adapted to the tooth 524 is formed in the upper end of the bottom cover 53. Rubber pads 535 are fixedly connected to both arc surfaces inside the connection groove 534.

[0042] The rubber pads 535 have elasticity and high friction. When the tooth 524 enters between the rubber pads 535, it will be squeezed by them and subjected to friction to be retained inside the connection groove 534, achieving temporary sealing. The through hole 532 at the bottom can insert an auxiliary rod with a diameter below a predetermined value. When the upper top cover 51 is opened, the piston block 531 is pushed upward by the auxiliary rod, thereby pushing the slope soil sample inside the sampling cylinder 52 upward to achieve the complete extraction of the soil sample, without the need for manual triggering or direct contact with the operator, reducing the influence on the effective components in the corresponding sample and improving the detection accuracy.
