DETAILED DESCRIPTION In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings: Example: like Figures 1 to 5 As shown, the present invention provides a multifunctional soil collector, comprising: A drill bit 1, to which a drill rod 2 is connected; The driving part 3 is connected to the drill rod 2 to drive the drill rod 2 to drive the drill bit 1 to rotate into the soil; The casing 4 and the sliding sleeve 101 are provided on the drill pipe 2 and a collection port 40 is provided thereon; The multi-channel sampling chamber 5 is provided at the end of the drill bit 1 and is sleeved on the drill rod 2; Multiple sampling tubes 6 are detachably arranged in the multi-channel sampling chamber 5; The soil sampling member 7 is rotatably arranged in the multi-channel sampling chamber 5 and is located above the sampling tube 6. A torsion spring 72 is also sleeved on the soil sampling member 7; The casing 4 rotates and slides upward in the multi-channel sampling chamber 5 through the guide protrusion 42 thereon, so that the collection port 40 moves to the soil collection piece 7, and the soil collection piece 7 rotates and opens to enter the soil, so that the drill rod 2 rotates or moves deeply to cause the soil collection piece 7 to push the soil into the sampling tube 6 for collection.

[0017] See also Figure 5 The multi-channel sampling chamber 5 is provided with a plurality of sample slots 51 along the circumferential direction. A slot is provided in the sample slot 51 . The soil sampling piece 7 is rotatably provided at the upper end of the sample slot 51 , and the sampling tube 6 is detachably inserted into the slot at the lower portion of the sample slot 51 .

[0018] See also Figure 5 The multi-channel sampling chamber 5 is circumferentially provided with a plurality of L-shaped grooves 52. The guide protrusions 42 are rotated by the sleeve 4 to enter the L-shaped grooves 52. The multi-channel sampling chamber 5 is also provided with an annular groove 53, which is connected to the L-shaped grooves 52. By providing the L-shaped grooves 52 and annular grooves 53, the sleeve 4 can rotate the multi-channel sampling chamber 5 via the guide protrusions 42, thereby rotating the collection port 40 to vertically align with the soil-collecting member 7. The sleeve 4 continues to slide upward in the L-shaped grooves 52, causing the collection port 40 to slide horizontally with the soil-collecting member 7. The soil-collecting member 7 is then opened outward by the torsion spring 72 and inserted into the soil. At this time, when the drill bit 1 is pushed downward into the soil, the soil-collecting member 7 pushes the soil into the sampling tube. When sampling is completed, the sleeve 101 tube 4 is slid downward to slide the guide protrusion 42 inside it to the annular groove 53, and then the sleeve 4 is rotated to disengage the guide protrusion 42 from the "L"-shaped groove 52. During this process, the collection port 40 slides vertically downward to push the soil collection piece 7 to rotate and be stored in the multi-channel sampling chamber 5.

[0019] Furthermore, scale lines are provided on the casing 4 to facilitate sampling of soil at different depths.

[0020] See also Figure 3 and Figure 9 The upper portion of the casing 4 is rotatably provided with a threaded sleeve 41. The drill rod 2 is provided with multiple external threads spaced axially therebetween. Sliding sleeves 101 are provided on the drill rod 2, allowing the threaded sleeves 41 to slide and engage with the external threads. The threaded sleeve 41 allows the casing 4 to be locked onto the external threads of the drill rod 2 after sliding. The external threads include upper and lower external threads. The upper external threads are used to lock the casing 4 after it has slid to its highest point; the lower external threads are used to lock the casing 4 at the base of the drill bit 1 to prevent the casing 4 from sliding automatically in its initial state.

[0021] Furthermore, in order to prevent the sleeve 4 from automatically rotating relative to the base of the drill bit 1, a clamping protrusion can be provided on the drill bit 1 to engage with the collection port 40. When the soil collecting member 7 is needed for collection, the sleeve 101 tube 4 is first slid upward, and then the guide protrusion 42 is aligned with the horizontal inlet of the "L"-shaped groove 52. The sleeve 4 is then rotated to allow the guide protrusion 42 to enter the "L"-shaped groove 52. The sleeve 101 tube 4 is then slid downward to allow the guide protrusion 42 to move linearly upward in the "L"-shaped groove 52.

[0022] See also Figure 1 The drive unit 3 is a fuel or gasoline engine, the output end of which is plugged into the upper end of the drill rod 2. Furthermore, a handle is provided at the end of the drill rod 2 for manually rotating the drill rod 2. Furthermore, a spiral groove is provided on the drill bit 1 to facilitate rapid penetration of the drill bit 1 into the soil.

[0023] As another embodiment of the present application, Figure 11 and Figure 12 As shown, a cut surface is provided on the inner wall of one side of the soil collecting member 7 so that when the collector rotates in the soil, the cut surface is used to push the soil into the sampling tube 6. By providing the cut surface, the soil collecting member 7 can push the soil into the sampling tube when the collector rotates and penetrates into the soil.

[0024] As another embodiment of the present application, Figure 6As shown, a fixed disk 8 is provided on the drill rod 2. A push rod 81 is circumferentially slidably provided on the fixed disk 8. A push block 82 is provided at the end of the push rod 81. A "U"-shaped member 71 is provided on the soil-collecting member 7, which abuts against the push block 82. A "V"-shaped member 83 is also rotatably provided on the fixed disk 8. The protrusion at the end of the "V"-shaped member 83 abuts against the pressure piece at the end of the push rod 81. A pressing protrusion 43 is provided in the sleeve 4 for pushing the "V"-shaped member 83 to press the push rod 81 downward. When the sleeve 4 slides to the upper end of the "L"-shaped groove 52, the pressing protrusion 43 pushes the "V"-shaped member 83 to swing on the fixed disk 8, causing the "V"-shaped member 83 to press down on the pressure piece on the push rod 81. The push rod 81 is pulled downward by the spring 84, which drives the push block 82 downward to push the "U"-shaped member 71 downward, thereby rotating and opening the soil-collecting member 7 and inserting it into the soil.

[0025] See also Figure 6 The push rod 81 is sleeved with a spring 84 for resetting, so as to facilitate the automatic return of the push rod 81.

[0026] See also Figure 8 The pressing protrusion 43 is vertically opposite to the collecting port 40 and is located above the collecting port 40 and the guide protrusion 42, so that when the guide protrusion 42 moves to the top of the "L"-shaped groove 52, the pressing protrusion 43 can push the "V"-shaped member 83 to rotate on the fixed disk 8.

[0027] As another embodiment of the present application, Figure 10 As shown, the drill bit 1 also includes a protective tube 21, the lower end of which is connected to the end of the drill bit 1 via a connecting piece, and the sleeve 4 is slidably positioned on the protective tube 21. The provision of the protective tube 21 prevents the sleeve 4 from automatically rotating relative to the drill bit 1 during the rotation of the collector into the soil, and also reduces the resistance to manually rotating the sleeve 4 when collecting soil.

[0028] As another embodiment of the present application, Figure 7 As shown, it also includes a support leg 10, which is arranged on the sleeve 4 through a sliding sleeve 101 to facilitate the removal of the support leg 10. The sliding sleeve 101 is provided with an expansion mechanism 9 for adjusting the expansion angle of the support leg 10.

[0029] See also Figure 7 The deployment mechanism 9 includes a second screw sleeve 91, a threaded tube 92, and a pull rod 93. The threaded tube 92 is fixed to the sliding sleeve 101, and the second screw sleeve 91 is threadedly connected to the threaded tube 92. The lower end of the second screw sleeve 91 is rotatably provided with a collar 94, and the ends of the pull rod 93 are respectively hinged to the collar 94 and the support leg 10. By providing the second screw sleeve 91, when the second screw sleeve 91 is rotated, the collar 94 can be driven to move up and down, thereby driving the pull rod 93 to control the deployment and storage of the support leg 10.

[0030] Furthermore, a pre-tightening bolt is provided on the sliding sleeve 101 , and a knob is provided on the pre-tightening bolt. The pre-tightening bolt is rotated to make the starting end contact with the sleeve 4 or the protective tube 21 to lock the deployment mechanism 9 and the support leg on the sleeve 4 or the protective tube 21 .

[0031] Working principle of the present invention: When in use, the collector is supported vertically on the soil surface by the supporting feet 10, and then the driving part 3 is used to drive the drill rod 2 to drive the drill bit 1 to rotate and penetrate into the soil. The depth of insertion into the soil is observed by the scale line set on the casing 4 or the protective tube 21. After reaching the specified depth, the screw sleeve 41 is rotated, and the sleeve 101 tube 4 is slid upward to make the guide protrusion 42 and the horizontal inlet of the "L"-shaped groove 52 horizontally aligned, and then the sleeve 4 is rotated again to make the guide protrusion 42 enter the "L"-shaped groove 52, and then the sleeve 101 tube 4 is slid upward. The guide protrusion 42 moves linearly upward within the L-shaped groove 52 until the collection port 40 is aligned horizontally with the soil collection member 7. During this process, the downward pressing protrusion 43 within the sleeve 4 pushes the V-shaped member 83 to swing on the fixed plate 8, causing the V-shaped member 83 to press down on the pressure plate on the push rod 81, causing the push rod 81 to stretch the spring 84 downward, driving the push block 82 downward, pushing the U-shaped member 71 downward, thereby rotating and inserting the soil collection member 7 into the soil. The drill rod 2 is rotated or deepened into the drill rod 2, causing the soil collection member 7 to push the soil into the sample tube. When sampling is completed, the sleeve 101 tube 4 is slid downward to slide the guide protrusion 42 within it to the annular groove 53, and then the sleeve 4 is rotated to disengage the guide protrusion 42 from the L-shaped groove 52. During this process, the collection port 40 slides vertically downward, pushing the soil collection member 7 to rotate and be stored in the multi-channel sampling chamber 5, facilitating the next sampling.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, use the above technical content to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes.
