Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling, in particular to a soil sampling device for ecological environment monitoring. Background Art

[0002] When sampling soil in arid areas, the soil will fall during the lifting process, affecting the sampling effect. Therefore, the general method used in this case is to moisten the soil in advance. However, this type of soil sampling device mostly adopts a method of watering from above, such as CN216586482U, a soil sampling device for highway inspection. This will cause the upper soil to be overly moist, while the lower soil is still in a dry state. If it is fully moistened, it takes a long time to wait, so it needs to be improved.

[0004] Preferred technical solution 1: The sampling tube is a double-walled tube, and an annular chamber is formed between the two walls. The drainage hole is opened on the inner wall of the sampling tube and connected to the annular chamber. At the same time, the top of the annular chamber is connected to the top of the water cylinder through a pipe.

[0005] Preferred technical solution 2: A soil sampling device for ecological environment monitoring also includes a support frame and an externally threaded cylinder penetrating the support frame, wherein the externally threaded cylinder is sleeved on the outside of the water cylinder, and the externally threaded cylinder passes through a threaded hole opened on the support frame.

[0006] Preferred technical solution three: a control disk is rotatably provided on the support frame, the control disk is slidably sleeved on the external threaded cylinder, a ring gear is sleeved on the control disk, and a motor is provided on the support frame, and the output shaft of the motor is meshed with the ring gear through a driving gear provided.

[0007] Preferred technical solution four: The bottom opening of the sampling tube is a conical opening, which is used to compact the soil entering the sampling tube to prevent the soil from being too loose.

[0008] The above structure enables this solution to have the following beneficial effects:

[0009] 1. Through the structural setting, a water cylinder is set on the top of the sampling cylinder, and the water in the water cylinder is automatically discharged while the soil is being sampled, so that the soil obtained by the sampling cylinder is evenly moistened, the sampling effect is improved, and there is no need to wait, thus shortening the effective sampling time;

[0010] 2. The conical structure at the bottom of the sampling tube allows the soil sample entering the sampling tube to be compressed while being moistened, further improving the integrity of soil sampling and preventing soil from scattering. BRIEF DESCRIPTION OF THE DRAWINGS
