DETAILED DESCRIPTION

[0041] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0042] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] Embodiment 1:

[0044] like Figure 1-9 As shown, a soil quality detection sampling device for soil and water conservation comprises a cylinder 1, a conical shell 5 is threadedly connected to the bottom of the cylinder 1, and a side hole 1 6 and a side hole 2 7 are opened on the circumferential outer wall of the cylinder 1, an inner plate 2 is welded to the circumferential inner wall of the cylinder 1, and a rotating shaft 28 is rotatably connected to the through hole opened inside the inner plate 2, and a partition block 8 is fixed to the bottom of the rotating shaft 28, an elastic member 1 is installed on the inner wall of the inner plate 2, and a lifting plate 16 is fixed on the elastic member, a vertical plate 17 is welded to the top of the inner plate 2 through a support rod 4, and a sliding rod 22 is slidably connected to the through hole opened on the surface of the vertical plate 17, and an arc block 20 is fixed to one end of the sliding rod 22, and a spring 21 is clamped between one end of the arc block 20 and the outer wall of one side of the vertical plate 17, and a sealing block 9 is fixed to the other end of the sliding rod 22, a connecting plate 14 is welded to the side wall of the lifting plate 16, and a convex block 15 used in conjunction with the arc block 20 is welded to the outer wall of one side of the connecting plate 14;

[0045] The partition block 8 is composed of a plurality of fan-shaped blocks. When the conical shell 5 and the bottom of the cylinder 1 are threadedly connected, the chamber formed by the plurality of fan-shaped blocks and the top of the conical shell 5 can collect soil samples. In this embodiment, the number of fan-shaped blocks is preferably three groups, and the three groups of fan-shaped blocks constitute three chambers. In the initial stage, the side wall of the lifting plate 16 and the side hole 2 7 are aligned to cover the side hole 2 7. When it is necessary to collect soil samples, the cylinder 1 and the conical shell 5 are inserted into the ground. The conical shell 5 is conical to improve the soil breaking ability. The lifting plate 16 blocks the side hole 2 7, so before the side hole 2 7 reaches the sampling depth, the soil sample will not enter the cylinder 1 through the side hole 2 7. When the side hole 2 7 moves to the soil layer of the set depth, the lifting plate 16 is lifted as a whole. After being lifted, the lifting plate 16 is gradually misaligned with the side hole 2 7, and one of the chambers is rotated to a position aligned with the bottom of the lifting plate 16, so that the soil sample finally enters the chamber through the side hole 2 7, thereby realizing the sampling of the soil sample;

[0046] The lifting plate 16 moves synchronously with the protrusion 15 during the rising process. When the protrusion 15 moves to the arc block 20, it squeezes the arc block 20. After being squeezed, the arc block 20 drives the slide bar 22 and the sealing block 9 to move outward along the side hole 1 6. The sealing block 9 squeezes the soil sample during the movement. After being squeezed, the soil sample is accelerated to enter the chamber through the side hole 2 7, thereby accelerating the detection sampling efficiency.

[0047] When one of the chambers has completed soil sampling, the remaining chambers are rotated to a position directly opposite the bottom of the lifting plate 16, so that multiple groups of sampling can be achieved without pulling out the cylinder 1 and the conical shell 5. At the same time, by adjusting the insertion depth of the cylinder 1 and the conical shell 5, sampling of soil samples at different depths can be achieved.

[0048] A slot 33 is provided on the circumferential outer wall of the rotating shaft 28, and a limiting mechanism is fixed on the top outer wall of the built-in plate 2. The limiting mechanism includes a threaded rod 10 and a square plate 23. The square plate 23 is welded to the top outer wall of the built-in plate 2, and the threaded rod 10 is threadedly connected to the inner wall of the threaded hole provided on the surface of the square plate 23, and a plug 11 matching the inner diameter of the slot 33 is fixed at one end of the threaded rod 10.

[0049] When the chamber is rotated to be aligned with the bottom of the lifting plate 16, in order to ensure the stability of the partition block 8, when the chamber and the bottom of the lifting plate 16 are aligned, the slot 33 opened on the outer wall of the circumference of the rotating shaft 28 and the plug 11 are aligned, and in the process of rotating the threaded rod 10, the plug 11 is gradually inserted into the inner wall of the slot 33, thereby limiting the partition block 8.

[0050] The elastic member 1 includes a mounting plate 13 and a mounting plate 2 19, the mounting plate 13 is welded to the inner wall of the built-in plate 2, and the mounting plate 2 19 is welded to the side wall of the lifting plate 16, and a spring 18 is clamped between the bottom of the mounting plate 2 19 and the top of the mounting plate 13;

[0051] The elastic force of the spring 18 is utilized to reset the lifting plate 16 after a sampling is completed.

[0052] The sampling device also includes a gripping assembly, which includes a gripping handle 3 and a sliding frame 26. The sliding frame 26 is welded to the outer wall of the bottom of the gripping handle 3, and a driving block 29 is welded to the inner wall of the sliding frame 26. The outer wall of the circumference of the rotating shaft 28 is respectively provided with an annular groove 34 and a vertical groove 36 adapted to the outer diameter of the driving block 29, and the annular groove 34 and the vertical groove 36 are connected. An elastic member 2 is fixed to the top of the rotating shaft 28, and the top of the elastic member 2 is rotatably connected to the inner wall of the top of the sliding frame 26.

[0053] In the initial stage, the driving block 29 is located on the inner wall of the vertical groove 36 under the support of the elastic member 2. When it is necessary to drive the rotating shaft 28 and the partition block 8 to rotate, the driving block 29 is used to drive the rotating shaft 28 to rotate synchronously when the handle 3 rotates.

[0054] The through hole at the bottom of the sliding frame 26 is slidably connected with a lever 35, and a pad 24 is welded to the bottom of the lever 35, and an inclined block 25 is welded to the top outer wall of the pad 24, and a lifting block 12 used in conjunction with the inclined block 25 is welded to the top outer wall of the lifting plate 16;

[0055] When the rotating shaft 28 is limited by the plug 11, the chamber and the bottom of the lifting plate 16 are aligned. When the lifting plate 16 needs to be driven upward, the handle 3 is pressed down to make the driving block 29 move downward along the corresponding vertical groove 36. When the driving block 29 moves to the junction between the vertical groove 36 and the annular groove 34, the handle 3 is rotated. During the rotation, the handle 3 drives the driving block 29 to slide along the annular groove 34. During this process, the elastic member 2 is compressed, and the sliding frame 26 drives the lever 35, the pad 24 and the inclined block 25 to rotate. When the inclined block 25 moves to the lifting block 12 during the rotation, it lifts the lifting block 12. After the lifting block 12 is lifted, it drives the lifting plate 16 to move upward, thereby realizing the detection and sampling of soil samples.

[0056] The second elastic member includes a T-shaped rod 32 and a sleeve 27, wherein the T-shaped rod 32 is fixed to the top outer wall of the rotating shaft 28, and the sleeve 27 is slidably connected to the outer wall of the T-shaped rod 32, and the top of the sleeve 27 is rotatably connected to the top inner wall of the sliding frame 26, and a spring 31 is clamped between the top inner wall of the sleeve 27 and the top outer wall of the T-shaped rod 32;

[0057] The spring 31 is provided so that the driving block 29 is reset when it moves to the boundary between the vertical groove 36 and the annular groove 34 again.

[0058] A coil spring 30 is clamped between the inner wall of the top of the sliding frame 26 and the outer wall of the circumference of the sleeve 27;

[0059] The resilience of the coil spring 30 is utilized to allow the driving block 29 to be reset after rotating along the inner wall of the annular groove 34 .

[0060] In this embodiment: the sampling device is inserted into the ground to a predetermined depth. Since the lifting plate 16 blocks the side hole 27, the soil sample will not enter the cylinder 1 before reaching the sampling depth. When the side hole 27 reaches the set soil layer, the handle 3 and the drive block 29 are rotated to drive the rotating shaft 28 and the partition block 8 to rotate, and one of the chambers is rotated to a position aligned with the bottom of the lifting plate 16. When the chamber is aligned with the bottom of the lifting plate 16, the slot 33 on the rotating shaft 28 is aligned with the plug 11, and the threaded rod 10 is rotated to insert the plug 11 into the slot 33, so as to limit the partition block 8. Then, the lifting plate 16 is controlled to move upward by the holding assembly. The specific operation steps are: pressing down the handle 3 to make the drive block 29 move down along the vertical groove 36, and rotating the handle 3 when it reaches the junction of the vertical groove 36 and the annular groove 34. The drive block 29 moves along the annular groove 34. The groove 34 slides and compresses the elastic member 2 at the same time. At this time, the sliding frame 26 drives the lever 35, the pad 24 and the inclined block 25 to rotate. The inclined block 25 pushes the lifting block 12, thereby driving the lifting plate 16 to move upward. During the upward movement of the lifting plate 16, the convex block 15 squeezes the arc block 20, driving the slide bar 22 and the sealing block 9 to move outward along the side hole 16, squeezing the soil sample to accelerate its entry into the chamber to complete the sampling of the soil sample. After the sampling is completed, the lifting plate 16 is reset by the rebound force of the spring 18. At the same time, the spring 31 and the coil spring 30 respectively reset the drive block 29 and the sliding frame 26 to the initial state. Repeat the above operation to rotate the remaining chambers to a position opposite to the bottom of the lifting plate 16 to achieve multiple groups of sampling. By adjusting the insertion depth of the cylinder 1 and the conical shell 5, soil samples of different depths can be collected.

[0061] Embodiment 2:

[0062] A method for using a soil quality detection sampling device for soil and water conservation comprises the following steps:

[0063] S1: insert the cylinder 1 and the conical shell 5 into the ground to a predetermined depth, and the lifting plate 16 blocks the side hole 2 7 to prevent the soil sample from entering the cylinder 1 in advance;

[0064] S2: When the second side hole 7 reaches the set soil layer, the rotating handle 3 drives the rotating shaft 28 and the partition block 8 to rotate through the driving block 29, and one of the chambers is rotated to be aligned with the bottom of the lifting plate 16, and the threaded rod 10 is rotated to insert the plug 11 into the slot 33 to limit the partition block 8;

[0065] S3: Press the handle 3 downward to make the driving block 29 move downward along the vertical groove 36. When the handle 3 reaches the junction of the vertical groove 36 and the annular groove 34, rotate the handle 3. The driving block 29 slides along the annular groove 34 and compresses the elastic member 2. The sliding frame 26 drives the lever 35, the pad 24 and the inclined block 25 to rotate. The inclined block 25 pushes the lifting block 12 and drives the lifting plate 16 to move upward.

[0066] S4: During the upward movement of the lifting plate 16, the convex block 15 squeezes the arc block 20, driving the slide bar 22 and the sealing block 9 to move outward along the side hole 16, squeezing the soil sample and accelerating it to enter the chamber;

[0067] S5: After completing one sampling, the lifting plate 16 is reset by the rebound force of the spring 18, and at the same time, the spring 31 and the coil spring 30 reset the driving block 29 and the sliding frame 26 to the initial state, and the remaining chambers are rotated in turn to the position facing the bottom of the lifting plate 16, and the above operation is repeated to achieve multiple sets of sampling;

[0068] S6: Soil samples at different depths are collected by adjusting the insertion depth of the cylinder 1 and the conical shell 5.

[0069] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.

A method for using the soil quality detection and sampling device for soil and water conservation according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: inserting the cylinder (1) and the conical shell (5) into the ground to a predetermined depth, and using the lifting plate (16) to block the second side hole (7) to prevent the soil sample from entering the cylinder (1) in advance; S2: When the second side hole (7) reaches the set soil layer, the rotating handle (3) drives the rotating shaft (28) and the partition block (8) to rotate through the driving block (29), and one of the chambers is rotated to be aligned with the bottom of the lifting plate (16), and the threaded rod (10) is rotated to insert the plug (11) into the slot (33), so as to limit the partition block (8); S3: Press the handle (3) downward to make the driving block (29) move downward along the vertical groove (36). When the handle (3) reaches the junction of the vertical groove (36) and the annular groove (34), the driving block (29) slides along the annular groove (34) and compresses the second elastic member. The sliding frame (26) drives the lever (35), the pad (24) and the inclined block (25) to rotate. The inclined block (25) pushes the lifting block (12) to drive the lifting plate (16) to move upward. S4: When the lifting plate (16) moves upward, the convex block (15) squeezes the arc block (20), driving the slide bar (22) and the sealing block (9) to move outward along the side hole (6), squeezing the soil sample and accelerating it to enter the chamber; S5: After completing one sampling, the lifting plate (16) is reset by the rebound force of the spring (18), and at the same time, the spring three (31) and the coil spring (30) reset the driving block (29) and the sliding frame (26) to the initial state, and the remaining chambers are rotated in turn to the position facing the bottom of the lifting plate (16), and the above operation is repeated to achieve multiple sets of sampling; S6: Soil samples at different depths are collected by adjusting the insertion depth of the cylinder (1) and the conical shell (5).
