[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Reference Figures 1-6 The bottom end of the main body rod 1 is provided with a soil drilling assembly 2, and the soil drilling assembly 2 includes a hollow drill bit 201, and a support plate 202 is welded between the inner wall of the circumference of the hollow drill bit 201. A slide rod 203 is slidably inserted on the top of the support plate 202, and a bulldozer 204 is welded on the bottom end of the slide rod 203. A spring 206 is sleeved on the outer wall of the slide rod 203 to facilitate the reset of the bulldozer 204. A slider 205 is welded on the top of the slide rod 203. The slider 205 passes through the hollow drill bit 201 and is slidably connected to the hollow drill bit 201. The circumference of the slider 205 is welded with a slide cylinder 4. Pushing the slide cylinder 4 downward drives the slider 205 to move downward, thereby driving the bulldozer 204 to move downward under the connection action of the slide rod 203, thereby pushing the soil in the hollow drill bit 201 out, so as to detect the soil.

[0025] The top of the hollow drill bit 201 is provided with a connecting component 3, and one side of the hollow drill bit 201 is provided with two notches 301. The connecting component 3 includes two protrusions 302, which are integrally formed on one side of the main rod 1. The protrusions 302 are snap-fitted with the notches 301, so that the hollow drill bit 201 is easily installed at the bottom end of the main rod 1. A secondary magnetic block 304 is embedded in one side of the hollow drill bit 201, and a main magnetic block 303 is embedded in one side of the main rod 1. The main magnetic block 303 and the secondary magnetic block 304 are attracted to each other, so that the hollow drill bit 201 and the main rod 1 are easily pre-fixed. The circumferential outer wall of the main rod 1 is slidably sleeved with a connecting tube 305. The top and bottom ends of the tube 305 are embedded with lower magnetic rings 308, and the circumferential outer wall of the main rod 1 is welded with an upper iron ring 307. The lower magnetic ring 308 at the top of the connecting tube 305 attracts each other, which facilitates the fixation of the connecting tube 305. The circumferential outer wall of the hollow drill bit 201 is welded with a lower iron ring 306. The lower magnetic ring 308 at the bottom end of the connecting tube 305 attracts the lower iron ring 306, and the connecting tube 305 is pushed downward until the lower magnetic ring 308 at the bottom end of the connecting tube 305 attracts the lower iron ring 306, so that the connecting tube 305 is sleeved on the connection between the main rod 1 and the hollow drill bit 201, and then the hollow drill bit 201 is firmly fixed to the bottom end of the main rod 1.

[0026] Horizontal handles 5 are welded to the tops of both sides of the main rod 1, which is convenient for holding during sampling. A vertical handle 6 is welded to the top of the main rod 1, which is convenient for carrying the sampling device. The circumferential outer wall of the main rod 1 is rotatably sleeved with a storage box 7 through a bearing. A plurality of placement tubes 8 are fixedly inserted on the top of the storage box 7. The drilling assembly 2 is inserted into the placement tube 8, which is convenient for storing the drilling assembly 2. The top of the placement tube 8 is embedded with an upper magnetic ring 9, and the upper magnetic ring 9 is attracted to the lower iron ring 306, which is convenient for fixing the drilling assembly 2 when it is stored.

[0027] The working principle of this embodiment is as follows: during installation, first, the hollow drill bit 201 is installed on the bottom end of the main rod 1 by engaging the protrusion 302 with the recess 301, and the main magnetic block 303 and the auxiliary magnetic block 304 are attracted to each other to pre-fix the hollow drill bit 201 and the main rod 1, and then the connecting tube 305 is pushed downward until the lower magnetic ring 308 at the bottom end of the connecting tube 305 is attracted to the lower iron ring 306, so that the connecting tube 305 is sleeved on the connection between the main rod 1 and the hollow drill bit 201, thereby firmly fixing the hollow drill bit 201 to the bottom end of the main rod 1;

[0028] When in use, hold the horizontal handle 5 with both hands and press downward, so that the hollow drill bit 201 drills into the soil. Then, the soil enters the hollow drill bit 201 and is collected. When testing, push the slide cylinder 4 downward to drive the slider 205 to move downward, thereby driving the bulldozer 204 downward under the connection action of the slide rod 203, thereby pushing the soil in the hollow drill bit 201 out for soil testing.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
