It solves the difficult problem of accurately collecting soil samples for soil testing, fertilization, soil monitoring, and other soil and fertilizer work. It can collect soil samples conveniently, quickly, and accurately, and minimize sampling errors.

[0003] Among them, the electric soil environment monitoring sampling device uses an electric-driven robotic arm or drill rod to drill the soil. It is mainly composed of an electric motor, a drill bit, a control system, etc. Driven by the electric motor, the drill bit can rotate quickly and drill into the soil to complete the soil sampling process. At the same time, the control system can accurately control parameters such as sampling depth and rotation speed to meet different sampling needs.

[0023] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0024] like Figure 1 and 2 As shown, the present invention provides a soil environment monitoring sampling device, comprising a control box 1, a sampling tube 2, and an inner tube 3. The sampling tube 2 is rotatably disposed at the bottom end of the control box 1. The inner tube 3 is disposed within the sampling tube 2, slidably connected thereto, and can be removed from the sampling tube 2.

[0025] The sampling tube 2 is inserted into the soil by rotation. When it is pulled out, the soil remains in the inner tube 3, completing the sampling. After each sampling, the inner tube 3 is removed to obtain the soil sample, and a new inner tube 3 is inserted into the sampling tube 2 to start the next sampling. This eliminates the need to remove the sampling tube 2 from the control box 1 for cleaning after each sampling, making operation convenient and improving sampling efficiency.

[0026] When the inner tube 3 is arranged in the sampling tube 2 , the outer end of the inner tube 3 is flush with the outer end of the sampling tube 2 .

[0027] like Figure 3 As shown, in a preferred embodiment, the inner tube 3 is composed of two semicircular half-tubes that are plugged into each other. The soil sample can be removed by separating the two half-tubes without the need for additional tools, making the operation convenient and efficient. Furthermore, the two separated half-tubes are easier to clean, improving cleaning efficiency.

[0028] like Figure 3 and 5As shown, the outer wall of the inner tube 3 has a plurality of strip-shaped sliding protrusions 31 arranged along its length. The inner wall of the sampling tube 2 has a plurality of strip-shaped sliding grooves 21 arranged along its length. The number of sliding protrusions 31 and the number of sliding grooves 21 are equal and correspond one to one. The sliding protrusions 31 are arranged in the sliding grooves 21, and the inner tube 3 and the sampling tube 2 are slidably connected through the sliding protrusions 31 and the sliding grooves 21. This sliding connection structure can not only stably set the inner tube 3 in the sampling tube 2 and rotate it to complete sampling, but also facilitate the installation of the inner tube 3 in the sampling tube 2 or removal from the sampling tube 2. In this embodiment, there are two sliding protrusions 31, which are arranged opposite to each other on the outer walls of the two half tubes.

[0029] The inner end of the sliding groove 21 has a fixing groove, and the bottom surface of the fixing groove is covered with a metal layer. Figure 4 As shown, the inner end of the sliding protrusion 31 has a fixing protrusion 32 that matches the fixing groove. The fixing protrusion 32 is made of a magnet. When the sliding protrusion 31 slides to the inner end of the sliding groove 21, the fixing protrusion 32 is magnetically embedded in the fixing groove, further stably positioning the inner tube 3 within the sampling tube 2, thereby better completing the rotational sampling.

[0030] like Figure 5 As shown, in a preferred embodiment, the device further includes an electric telescopic rod 4. One end of the electric telescopic rod 4 is fixed to the control box 1, and the other end extends into the sampling tube 2, allowing for extension and retraction. The inner tube 3 is located outside the electric telescopic rod 4. When the electric telescopic rod 4 extends, the inner tube 3 is pushed out of the sampling tube 2.

[0031] The movable end of the electric telescopic rod 4 is fixed with a push block 41 that matches the cross section of the inner tube 3, and a rubber pad 42 is glued to the outside of the push block 41. The push block 41 and the rubber pad 42 can better push the inner tube 3 out of the sampling tube 2 to avoid damage to the inner tube 3.

[0032] like Figure 6As shown, the bottom end of the control box 1 is provided with an annular rotating base 51. The rotating base 51 fits over the electric telescopic rod 4 (the portion of the rod that does not extend or retract). It is rotatably connected to the rod 4 via bearings, allowing it to rotate relative to the rod 4 and the control box 1. Alternatively, the rotating base 51 can be rotatably connected to the control box 1 via bearings, with the rod 4 extending through the rotating base 51 and allowing it to rotate relative to the rod 4 and the control box 1. The end of the sampling tube 2 is fixed to the outer side of the rotating base 51. A ring-shaped driven gear 52 is fixed to the inner side of the rotating base 51. A rotatable driving gear 53 is provided within the control box 1, with the driven gear 52 meshing with the driving gear 53. A motor 54 is also provided within the control box 1. The output shaft of the motor 54 is fixed to the driving gear 53, driving the driving gear 53 to rotate. The motor 54 rotates the driving gear 53, which in turn rotates the driven gear 52, which in turn rotates the rotating base 51, causing the sampling tube 2 to rotate accordingly. and driven gear 52

[0033] In a preferred embodiment, a handle is provided on the control box 1 to facilitate operation by staff.

[0034] The working process of the soil environment monitoring sampling device of the present invention is as follows: the inner tube 3 is inserted into the sampling tube 2, the sliding protrusion 31 slides to the terminal end of the sliding groove 21, and the fixed protrusion 32 is magnetically embedded in the fixed groove to complete the installation of the inner tube 3. Then the handheld control box 1 places the sampling tube 2 on the soil, starts the motor 54, drives the sampling tube 2 to rotate, and applies downward pressure during the rotation of the sampling tube 2 to make the sampling tube 2 drill into the soil. After the sampling tube 2 drills into the soil to a certain depth, the motor 54 is turned off and the sampling tube 2 stops rotating. The sampling tube 2 is then pulled out, and the soil remains in the inner tube 3, completing the sampling. Finally, the electric telescopic rod 4 is started to extend it to push the inner tube 3 out, and then the two half-tubes constituting the inner tube 3 are disassembled to remove the soil sample.
