Description

Technical Field

[0001] The utility model belongs to the technical field of soil sampling, and in particular relates to a tobacco field soil sampling device. Background Art

[0002] In the tobacco industry, field soil sampling and testing is an important part. Only by understanding the condition of the soil and the actual needs of tobacco can we prescribe the right medicine and apply fertilizer scientifically, thereby improving tobacco production and quality. Field soil sampling generally involves collecting samples of the cultivated layer. The cultivated layer usually refers to the 2 cm thick soil layer on the surface of the farmland. When sampling, the cultivated layer soil is collected from several points around the sampling point. After equal and uniform mixing, the mixed soil sample represents the soil sample at the sampling point. In order to ensure the credibility of farmland soil monitoring data, the number of points for the mixed sample of the cultivated layer soil mixture must be at least 5.

[0003] The existing field soil sampling device is provided with a shovel and a cylindrical sampling tube. When sampling with a shovel, it is necessary to squat and dig the soil vigorously, which is laborious and the soil sample is uneven. When sampling with a cylindrical sampling tube, the sampling tube is pressed by hand to immerse the sampling tube in the soil, which is also laborious. For a small sampling tube, the operator needs to squat or bend down to take samples. Such repeated squatting or bending down will greatly increase the fatigue of the operator. In addition, it is not convenient to pour the sampled soil in the sampling tube out of the sampling tube.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content
