[0002] Land reserves are a crucial component of urban construction and development. Reserved land can be used for a variety of purposes, including commercial development, residential construction, and public infrastructure development. Soil quality crucially impacts these subsequent uses. For example, soil contamination in residential construction can pose a potential health threat to residents. For agricultural land reserves, soil fertility and composition directly determine crop growth. Therefore, detailed soil sampling and analysis are essential during the land reserve process to accurately assess soil quality.

The mounting seat 4 is connected with a housing 8. The motor 5 drives the drum to rotate through the cooperation of the gear 6 and the protrusion 7, so that the drum rotates through the thread. The pattern enters the soil for sampling, the electric push rod 9 is installed on the turntable 2, the output end of the electric push rod 9 passes through the turntable 2 and is connected to the push plate 10, the push plate 10 is slidably connected to the inner wall of the drill tube 1, so that the electric push rod 9 drives the push plate 10 to move, so that the push plate 10 discharges the soil in the drill tube 1, and a mounting plate 17 is installed on the shell 8. The top of the mounting plate 17 is fixedly connected to a fixing column 18, and the top of the fixing column 18 is fixedly connected to a handle 19. A press switch 20 and an adjustment switch 21 are installed on the handle 19. The motor 5 is turned on by pressing the switch 20, and the forward and reverse rotation of the motor 5 is controlled by adjusting the switch 21.

[0027] It should also be noted that the connecting plate 11 is connected to the shell 8, and a plurality of slides 13 are fixedly connected to the connecting plate 11, and a slide rod 14 is slidably connected inside the slide rod 13. The bottom end of the slide rod 14 is fixedly connected to the pressure plate 12, and a spring 15 is sleeved on the slide rod 13 and the slide rod 14.
