[0013] (III) Beneficial effects
[0014] Compared with the prior art, the present utility model provides a device for collecting undisturbed soil samples in the rhizosphere of shrubs, which has the following beneficial effects:
[0015] 1. For the device for collecting undisturbed soil samples in the rhizosphere of shrubs, through the exquisitely designed sampling head and push block structure, the disturbance to the shrub roots and rhizosphere soil during the collection process is effectively reduced, thereby ensuring that the collected soil samples can maintain their original physical, chemical and biological characteristics to the greatest extent, providing higher-quality sample data for scientific research.
[0016] 2. For the device for collecting undisturbed soil samples in the rhizosphere of shrubs, through the T-shaped grip and foot pedal design, the operator can control the movement of the push block with one hand, while the two feet assist in stabilizing, greatly simplifying the collection process and improving the collection efficiency. In addition, the application of the eccentric block also uses the lever principle to further assist the movement of the push block, making the entire collection process smoother and faster.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1-3 , a device for collecting undisturbed soil samples from the rhizosphere of shrubs, comprising a sampling cylinder 8, a sampling head 9 is fixed at the lower end of the sampling cylinder 8, a lower cover 5 is fixed at the upper end of the sampling cylinder 8, the lower cover 5 is movably connected to the upper cover 4 by an internal hexagonal screw 3, a push block 10 is arranged inside the sampling cylinder 8, one end of the push block 10 is fixedly connected to one end of a push rod 2, the other end of the push rod 2 is sleeved with a T-shaped grip 1, two foot pedals 7 are fixed on the circumferential outer surface of the sampling cylinder 8, and a rubber block 6 is fixed on the upper surface of the foot pedal 7.
[0024] Further, the inside of the T-shaped grip 1 is hollow, and the lower end of the push rod 2 is sleeved with the push rod 2.
[0025] Further, a fixing column 12 is fixed inside the upper end of the sampling cylinder 8, a circular hole is arranged inside the fixing column 12, and the fixing column 12 is sleeved on the circumferential outer surface of the push rod 2.
[0026] Further, the inside of the lower cover 5 has the same size as the circular cross-section of the sampling cylinder 8.
[0027] Further, the edge parts of the surfaces of the upper cover 4 and the lower cover 5 are rounded.
[0028] Further, an eccentric block 11 is arranged between the push block 10 and the fixing column 12, the eccentric block 11 is sleeved on the circumferential outer surface of the push rod 2, the inside of the eccentric block 11 is a hollow structure, and the area of one side of the push block 10 is larger than the other end.

[0030] Working principle: For a device for collecting undisturbed soil samples from the rhizosphere of shrubs of the present utility model, during use, the operator first steps on the foot pedal 7 with both feet, and the rubber block 6 is used to increase the comfort and stability of stepping. Subsequently, hold the T-shaped grip 1 by hand to apply force to the foot pedal 7, and cut the soil sample at the root of the shrub multiple times. After the cutting is complete, the soil sample enters the interior of the sampling cylinder 8, and the T-shaped grip 1 is pushed to slide downward along the circular hole in the fixed column 12. The movement of the push rod 2 drives the push block 10 fixedly connected thereto to move downward inside the sampling cylinder 8.
