[0002] In agricultural production, the evaluation of cultivated land quality is a vital task, which is directly related to the growth, yield and quality of crops and is of great significance for the sustainable development of agriculture. One of the key steps in evaluating soil quality and characteristics is soil sampling and analysis.

[0003] Traditional soil sampling is usually done manually, where operators need to use manual tools (such as shovels, drills, etc.) to take samples deep into the soil, and then send the samples to the laboratory for analysis. However, manual sampling has some problems, such as the sampling depth is difficult to control, the sampling position is difficult to determine, and the sampling efficiency is low. These problems may lead to incomplete and inaccurate sampling, thus affecting the accuracy and reliability of the evaluation results.

[0033] The excavator includes a handle A3, which is cylindrical, a body 2 connected to the handle A3, which is also cylindrical, a drill bit 1 is arranged at the front end of the body 2, the drill bit 1 is connected to the output shaft of a motor 8 arranged in the body 2, the motor 8 is connected to a battery 5 arranged in the handle A3 through a wire 4, both ends of the handle A3 are sleeved with rubber sleeves 6, one end of the rubber sleeve 6 is sealed in a cylindrical shape, which is used for sealing and shaking hands, the outer surface of the rubber sleeve 6 is provided with anti-slip bumps or other anti-slip patterns, a power jack 7 is arranged on the rubber sleeve 6 at one end of the handle A3, which is used to charge the battery 5, and the body is wrapped by a shell.

[0034] The sampler includes a shield 9, which is semicircular. An I-shaped track 17 is arranged inside the shield 9. A C-shaped slider 18 is arranged on the track 17. The slider 18 is fixedly connected to the hydraulic press 10. A hydraulic interface 19 is arranged at one end of the hydraulic press 10 close to the slide rail. A piston 15 is arranged inside the hydraulic press 10. A pressure convex ring 16 is arranged at one end of the piston 15 close to the hydraulic interface 19. A connecting rod 14 is arranged at the other end of the piston 15. The connecting rod 14 is U-shaped. A connecting piece 13 is inserted on the connecting rod 14. The two are fixed with bolts 20. The connecting piece 13 is hingedly connected to the sampling box 12. A handle B11 is arranged on the top of the shield 9. The convex ring 16 is sealed with the shell of the hydraulic press 10. The convex ring 16 and the shell of the hydraulic press 10 form a closed cavity. The hydraulic interface 19 is connected to the hydraulic device. When working, the pipeline switch is turned on, and the hydraulic device injects hydraulic medium into the closed cavity to push the piston 15 out for sampling.

[0035] Sensors are provided on the drill bit 1 and the sampling box 12, and the sensors are used to detect soil hardness parameters. If hard stones are encountered, the sensors stop working. This principle can be realized by using different electrical conductivities of different soil bodies, such as different electrical conductivities of stones and loess.
