The term "and / or" as used in this description includes any and all combinations of one or more of the associated listed items.

[0043] The following combination Figures 1-13 The portable soil exploration sampling device of the present invention is described.

[0044] like Figures 1-6 and Figures 9-12 As shown, in one embodiment, the portable soil detection and sampling device includes, from top to bottom, a docking station 1, a sampling base 2, and a detection tube 3. The docking station 1 is movably connected to the sampling base 2, and further includes:

[0045] The sleeve 4 is rotatably mounted on the bottom of the docking seat 1;

[0046] The rotating cylinder 5 movably penetrates the sampling base 2 and is movably engaged with the sleeve cylinder 4 at the top and fixedly connected with the detection tube 3 at the bottom. The detection tube 3 is rotatably connected to the sampling base 2;

[0047] The fixed shaft 6 movably passes through the rotating cylinder 5 and the top passes through the sleeve cylinder 4 to be clamped with the docking seat 1;

[0048] The spiral plate 7 is provided on the outside of the rotating cylinder 5 and is used to transport the sampled soil upward;

[0049] Dispersing plates 8, arranged in an annular array outside the rotating cylinder 5, are located above the spiral plate 7;

[0050] The filter 10 is movably mounted in the sampling base 2;

[0051] A crushing assembly 9 is provided in the dispersion plate 8 and is used for crushing the sampled soil;

[0052] The analyzer 11 is installed on one side of the sampling base 2 .

[0053] Specifically, before sampling the soil, the docking seat 1 is clamped with the sampling base 2, the rotating cylinder 5 is clamped with the sleeve cylinder 4, the top of the fixed shaft 6 extends to the outside of the rotating cylinder 5, passes through the sleeve cylinder 4 and is clamped with the docking seat 1, the fixed shaft 6 remains fixed and does not move, the detection tube 3 is fixedly installed at the bottom of the sampling base 2, the motor of the sleeve cylinder 4 is started, the sleeve cylinder 4 rotates to drive the rotating cylinder 5 to rotate, the rotation of the rotating cylinder 5 drives the spiral plate 7 to rotate and the detection tube 3 to rotate, the outer side of the detection tube 3 is provided with a sharp cutting edge, which can drill into the ground when rotating to crush the soil, the detection tube 3 goes deep into the soil, and the soil is driven upward by the action of the spiral plate 7, the rotation of the rotating cylinder 5 will also drive the top dispersion plate 8 to rotate, the rotation of the dispersion plate 8 can push the collected soil to the four sides, and the finer soil passes through the filter screen 10, the filter screen 1 0 is set on the outside of the top of the spiral plate 7. There is a certain space between the outside of the filter screen 10 and the sampling base 2. The sampled soil enters the space. The position of the sampling base 2 for installing the filter screen 10 is a cylindrical design. The filter screen 10 is also an annular filter screen 10. Therefore, the space between the outside of the filter screen 10 and the sampling base 2 is also annular. The probe of the analyzer 11 penetrates into the space between the sampling base 2 and the filter screen 10 to perform real-time detection of the soil. The soil transported up by the spiral plate 7 is pushed toward the filter screen 10 by the rotating dispersion plate 8. In this process, the crushing component 9 set in the dispersion plate 8 can crush the soil and separate a part of the soil that is stuck together, so that it is convenient for the soil to pass through the filter screen 10 and enter the position where the probe is located, avoiding the sticky soil blocking a part of the filter holes of the filter screen 10 and affecting the collection efficiency.

[0054] See Figure 7-12 As shown, in this embodiment, the crushing assembly 9 includes a through hole 91, which is axially opened on both sides of the dispersion plate 8, with multiple holes arranged on one side. A movable cylinder 92 is movably arranged in the through hole 91. The diameter of the movable cylinder 92 is smaller than the diameter of the through hole 91. A conical cylinder 93 is movably arranged through one end of the movable cylinder 92. The conical cylinder 93 is in contact with the soil at one end away from the movable cylinder 92.

[0055] Specifically, the dispersion plate 8 will come into contact with the soil as the rotating cylinder 5 rotates. During this process, the movable cylinder 92 will move back and forth laterally along the through hole 91. The movement of the movable cylinder 92 will drive the movement of the conical cylinder 93. The end of the conical cylinder 93 that contacts the soil is sharp, which can effectively break up the soil clumps that are stuck together, preventing the soil clumps from clogging the filter 10 and affecting the collection efficiency.

[0056] See Figure 12 As shown, in this embodiment, a circular plate 94 is fixedly provided at the end of the conical cylinder 93 located inside the moving cylinder 92 , and the circular plate 94 is connected to the inner wall of the moving cylinder 92 via a positioning spring 95 , which is movably sleeved on the outer side of the conical cylinder 93 .

[0057] Specifically, the circular plate 94 moves back and forth laterally during the rotation of the dispersion plate 8. The movement of the circular plate 94 will drive the movement of the conical cylinder 93. The conical cylinder 93 can also move back and forth laterally during the revolution of the moving cylinder 92, which can further enhance the soil crushing effect. The circular plate 94 will also compress the positioning spring 95 and restore the positioning spring 95 to its original state during the reciprocating movement. The characteristics of the positioning spring 95 can realize the shaking of the conical cylinder 93 during the movement, which has a better soil crushing effect.

[0058] See Figure 12 As shown, in this embodiment, a cylinder 96 is rotatably arranged in the movable cylinder 92, and a plurality of balls 97 are arranged in a circular array at one end of the cylinder 96 near the circular plate 94, and a circular array is provided at one end of the circular plate 94 near the cylinder 96 with the same number of circular holes 98 as the number of the balls 97, and the balls 97 are movably abutted against the circular holes 98.

[0059] Specifically, the cylinder 96 rotates during the rotation of the dispersion plate 8, and the rotation of the cylinder 96 can drive the ball 97 to rotate. During the rotation of the ball 97, it will alternately abut and release the abutment with the circular hole 98. When the ball 97 is not abutting with the circular hole 98, it will push the circular plate 94 and the conical cylinder 93 to move toward the outside of the movable cylinder 92. This process will compress the positioning spring 95. When the ball 97 abuts with the circular hole 98, the circular plate 94 and the conical cylinder 93 are pulled back to the initial position under the action of the positioning spring 95. This will form the movement of the conical cylinder 93 and the shaking generated by the positioning spring 95, which can enhance the soil crushing effect.

[0060] See Figure 10-12 As shown, in this embodiment, a fixed cylinder 12 is fixedly arranged in the through hole 91, and the movable cylinder 92 is movably arranged inside the fixed cylinder 12. A curved groove 961 is opened on the outside of the cylinder 96, and a transverse groove 921 is opened on the outside of the movable cylinder 92. A limiting rod 13 is arranged in the fixed cylinder 12, and the limiting rod 13 is slidably connected to the transverse groove 921 and the end thereof is slidably fitted with the curved groove 961.

[0061] Specifically, when the dispersion plate 8 is not working, the tip of the conical cylinder 93 is located in the fixed cylinder 12. When the dispersion plate 8 rotates, the movable cylinder 92 moves back and forth laterally along the fixed cylinder 12. The movement of the movable cylinder 92 drives the cylinder 96, the disc and the conical cylinder 93 to move together. The tip of the conical cylinder 93 moves to the outside of the fixed cylinder 12, which makes it easier to crush the soil during the rotation. When the movable cylinder 92 moves outward toward the fixed cylinder 12, the limit rod 13 slides relative to the curved groove 961 and laterally. Under the cooperation of the limit rod 13 and the curved groove 961, the cylinder 96 will rotate, and the rotation of the cylinder 96 drives the disc The rotation of the ball 97 will eventually realize the reciprocating movement and shaking of the cone 93, which can improve the crushing effect of the soil. The tip part of the cone 93 abuts against the soil. If the soil moisture is high, the soil will adhere to the tip part of the cone 93 after the tip part contacts the soil, which will affect the subsequent crushing effect of the cone 93 on the soil. Therefore, when the cone 93 moves back into the fixed cylinder 12, the soil adhered to the tip will be separated from the adhesion with the tip part of the cone 93 by the abutting force of the outer wall of the fixed cylinder 12, which can help to ensure the subsequent crushing effect of the cone 93 on the soil.

[0062] See Figure 7 and Figure 8 As shown, in this embodiment, a moving groove 81 is opened on one side of the dispersion plate 8, a moving plate 14 is movably arranged in the moving groove 81, and a moving rod 15 is fixedly arranged on one side of the moving plate 14.

[0063] Specifically, during the rotation of the dispersion plate 8, the movable rod 15 moves back and forth laterally. The movement of the movable rod 15 drives the movable plate 14 to move back and forth laterally along the movable groove 81. When the movable plate 14 moves to the outside of the dispersion plate 8 along the movable groove 81, the contact area with the soil is expanded, and more soil is included in the beating range, thereby increasing the amount and efficiency of pushing the soil. The reciprocating motion of the movable plate 14 can produce a "stirring" and "draining" effect on the soil; when the movable plate 14 extends outward, it pushes the soil toward the filter 10; when the movable plate 14 retracts inward, the soil will fill the space left by the retraction of the movable plate 14 under its guidance, and adjust its own flow path at the same time. This movement method can reduce the accumulation and blockage of soil in front of the filter 10, allowing the soil to pass through the filter 10 more smoothly, thereby improving the pushing effect.

[0064] See Figure 8 As shown, in this embodiment, the moving rod 15 moves away from one end of the moving plate 14 and passes through the dispersion plate 8 and the rotating cylinder 5, and the end is located in the rotating cylinder 5. A positioning ring 16 is fixedly sleeved on the outer side of the fixed shaft 6, and a ring groove 161 is opened on the positioning ring 16. One end of the moving rod 15 is slidably embedded in the ring groove 161.

[0065] Specifically, when it is necessary to sample the soil, the rotating cylinder 5 is rotated. The rotation of the rotating cylinder 5 will drive the moving rod 15 to rotate. During the rotation of the moving rod 15, one end of the moving rod 15 rotates along the annular groove 161 opened by the positioning ring 16. A plurality of protrusions are provided in an annular array on the outer side of the positioning ring 16. Therefore, when the moving rod 15 rotates along the annular groove 161, the moving rod 15 will move back and forth laterally. The movement of the moving rod 15 will drive the moving plate 14 to move back and forth laterally, thereby improving the pushing effect on the soil.

[0066] See Figure 9 As shown, in this embodiment, the moving rod 15 is located in the inner part of the dispersion plate 8 and a moving frame 17 is fixedly sleeved on the outer side. Limiting grooves 171 are axially symmetrically provided on both sides of the moving frame 17. The number of limiting grooves 171 is the same as the number of through holes 91. A positioning rod 18 is fixedly provided on one side of the moving cylinder 92, and the positioning rod 18 is slidably connected to the limiting groove 171.

[0067] Specifically, the lateral reciprocating movement of the moving rod 15 will drive the moving frame 17 to move lateral reciprocatingly in the dispersion plate 8, and the moving frame 17 will move in the direction away from the rotating cylinder 5. The positioning rod 18 will move in the opposite direction relative to the moving frame 17, and the positioning rod 18 will slide relative to the limiting groove 171. The limiting groove 171 is composed of a straight groove and an oblique groove. It first slides along the straight groove of the positioning groove and then enters the oblique groove. Under the cooperation of the positioning rod 18 and the oblique groove, the moving cylinder 92 will be driven to move outward along the fixed cylinder 12, so that the soil can be crushed. Subsequently, the reverse movement of the moving rod 15 will drive the moving frame 17 to move in the reverse direction. Under the cooperation of the oblique groove and the positioning rod 18, the moving cylinder 92 will be moved toward the inside of the fixed cylinder 12, which can prevent the tip part of the conical cylinder 93 from adhering to the soil. The reciprocating movement of the moving cylinder 92 relative to the fixed cylinder 12 is achieved through the cooperation of the limiting groove 171 and the positioning rod 18.

[0068] See Figure 1 、 Figure 3 and Figure 13 As shown, in this embodiment, a squeezing mechanism is provided on the docking seat 1 for compacting the sampled soil to facilitate detection by the analyzer 11 .

[0069] Specifically, the soil pushed through the filter 10 by the dispersion plate 8 will accumulate in the space between the filter 10 and the sampling base 2. The squeezing mechanism can squeeze the soil sample after sampling to ensure that when the sampled soil is not dense enough, it can be appropriately compacted, so that the soil analyzer 11 can analyze the soil composition more accurately.

[0070] See Figure 1 、 Figure 3 and Figure 13As shown, in this embodiment, the extrusion structure 19 includes a sliding frame 191, the end of the sliding frame 191 movably passes through the bottom of the docking seat 1 and the top of the sampling base 2, and the end is fixedly connected to a pressure ring 192. A plurality of vertical rods 193 are provided on the docking seat 1. The sliding frame 191 is slidably connected to the vertical rods 193. The sliding frame 191 and the docking seat 1 are connected by a reset spring 194, and the reset spring 194 is movably sleeved on the outside of the vertical rod 193.

[0071] Specifically, the squeezing mechanism works as follows: the sliding frame 191 moves downward, and the downward movement of the sliding frame 191 will drive the pressure ring 192 to move downward. The size of the pressure ring 192 matches the space between the filter screen 10 and the sampling base 2. The downward movement of the pressure ring 192 will compact the soil placed in the space. During this process, the downward movement of the sliding frame 191 will move downward along the vertical rod 193, thereby compressing the reset spring 194. After the soil is compacted, the force applied to the sliding frame 191 is removed, and under the action of the reset spring 194, the sliding frame 191 and the pressure ring 192 will be driven to move upward to the initial position.

[0072] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of the present invention.
