Detailed Implementation

[0016] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-4 As shown, this utility model discloses a portable soil sampling device, which includes a handle 1 and a soil sampling head 11.

[0018] A storage groove 12 is provided in the middle of the handle 1, and the soil-taking head 11 is located in the storage groove 12, which facilitates the storage of the soil-taking head 11, reduces the overall size of the device, and makes it easy to carry. The right end of the storage groove 12 passes through the handle 1, and a sealing head 14 is provided at the right end of the handle 1. The sealing head 14 can prevent the soil-taking head 11 from sliding out of the storage groove 12.

[0019] A U-shaped seat 13 is fixed in the middle of the handle 1, and a connecting rod 2 is rotatably installed inside the U-shaped seat 13 via a rotating shaft. The U-shaped seat 13 is threaded with a fixing bolt 22 for fixing the connecting rod 2. By tightening the fixing bolt 22, the connecting rod 2 can be fixed and loosened, making it easy to adjust the angle of the connecting rod 2.

[0020] The end of the soil sampling head 11 is fixed with a threaded connector 111, and the connecting rod 2 has a threaded connection groove 21 that matches the threaded connector 111. Through the cooperation of the threaded connector 111 and the threaded connection groove 21, the soil sampling head 11 and the connecting rod 2 can be detachably connected, which makes it easy to replace different types of soil sampling heads 11 to adapt to different sampling needs.

[0021] The surface of the grip 1 is provided with an anti-slip pad, which can increase the friction when the user grips the grip 1, prevent the device from slipping during use, and improve the safety of use.

[0022] The connecting rod 2 consists of a sleeve 23 and a sliding rod 24. The right end of the sleeve 23 is rotatably mounted inside the U-shaped seat 13, and the sliding rod 24 is slidably mounted inside the sleeve 23. A threaded connection groove 21 is formed at the left end of the sliding rod 24. A locking assembly is provided between the sleeve 23 and the sliding rod 24. The locking assembly is used to fix the position of the sliding rod 24 inside the sleeve 23 and can adjust the overall length of the connecting rod 2.

[0023] The locking assembly includes a housing 3 fixed to the lower left side of the sleeve 23. A locking block 31 is slidably disposed inside the housing 3. Locking grooves 32 matching the locking block 31 are opened on both sides of the slide rod 24. A spring 33 is disposed between the lower side of the locking block 31 and the housing 3. A pull ring 34 extending out of the housing 3 is fixed to the lower side of the locking block 31. By pulling the pull ring 34, the locking block 31 can move downward against the elastic force of the spring 33, thereby exiting the locking groove 32. At this time, the slide rod 24 can be slid to adjust its position. After releasing the pull ring 34, the locking block 31 moves upward under the action of the spring 33 and enters the locking groove 32, thereby fixing the slide rod 24. There are multiple locking grooves 32 on the right side, which can adjust the position of the slide rod 24 in the sleeve 23, thereby adjusting the overall length of the connecting rod 2.

[0024] When the portable soil sampling device needs to be stored, first loosen the fixing bolt 22 to release the fixation of the sleeve 23, rotate the sleeve 23 upwards until it is parallel to the handle 1, and then loosen the fixing bolt 22 in the opposite direction to initially fix the sleeve 23. Next, pull down the pull ring 34 to make the locking block 31 move downwards against the elastic force of the spring 33, disengaging from the locking groove 32 on the right side of the slide rod 24. At this time, slide the slide rod 24 to the right to retract it into the sleeve 23. When the locking block 31 reaches the locking groove 32 on the left side of the slide rod 24, release the pull ring 34. The locking block 31 moves upwards under the action of the spring 33 and enters the locking groove 32, thus fixing the slide rod 24. Finally, place the soil sampling head 11 into the storage groove 12 in the middle of the handle 1 and install the sealing head 14 to complete the storage of the device.

[0025] When using this portable soil sampling device to collect soil samples, first remove the sealing head 14 and take the sampling head 11 out of the storage slot 12. Then pull down the pull ring 34 to disengage the locking block 31 from the locking groove 32 on the left side of the slide rod 24. Slide the slide rod 24 to the left so that it extends out of the sleeve 23. When the locking block 31 reaches the locking groove 32 on the right side of the slide rod 24, release the pull ring 34. The locking block 31 will enter the locking groove 32 under the action of the spring 33, fixing the position of the slide rod 24. Next, tighten the fixing bolt 22 to release the fixation of the sleeve 23. Rotate the sleeve 23 downward to a vertical position, and then tighten the fixing bolt 22 in the opposite direction to fix the sleeve 23 in the U-shaped seat 13. Finally, screw the threaded connector 111 at the end of the sampling head 11 into the threaded connection groove 21 at the left end of the slide rod 24 to complete the assembly of the device.

[0026] After the device is assembled, the user holds the anti-slip pads on both sides of the handle 1, aligns the soil sampling head 11 with the soil location to be sampled, and firmly inserts the soil sampling head 11 into the soil. Once the soil sampling head 11 reaches the required sampling depth, it is slowly lifted upwards, bringing the soil out with it, thus completing one soil sample collection. To collect soil samples at different locations or depths, the above operation can be repeated.
