Description

Intelligent detection device and method based on forestry soil nutrients

Technical Field

The invention belongs to the technical field of soil detection, and particularly relates to an intelligent detection device and method based on forestry soil nutrients.

Background

Soil nutrients refer to essential nutrient elements provided for crop growth by soil, and include 13 elements such as nitrogen (N), phosphorus (P), potassium (K) and the like. The content of the soil nutrients can be measured by soil measuring instruments such as a soil detector, a soil nutrient tester and the like. And then, by comparing the nutrient deficiency indexes of the soil, the nutrient content of the soil can be judged, so that the nutrients contained in the soil can be better utilized, and elements with insufficient content can be timely supplemented. When the existing soil detector detects nutrients in soil, a part of soil needs to be taken out from a position to be detected, and then the taken out soil is made into a sample solution and is placed into a detection port of the soil detector for detection. However, when the soil is sampled, for some soil with higher water content, the taken soil contains more water, so that the proportion of the soil in the sample is reduced, and the nutrient content of the soil in the prepared sample solution is lower, and the accuracy of the detection result is affected.

Step one: moving the detection trolley (1) to a place to be detected;

Step two: starting a second motor (111) to drive the drill spindle (4) and the drill cylinder (3) to rotate, and starting a first motor (104) after the rotation speeds of the drill spindle (4) and the drill cylinder (3) are stable, so as to drive the drill spindle (4) and the drill cylinder (3) to carry out drilling operation on a to-be-detected point;

Step three: the drilled soil can fall into the collecting tank (12) through the discharge hole;

Step four: part of the soil is taken out from the collecting tank (12) and made into a sample solution, and the sample solution is put into a detection port of the soil detector (2) for automatic detection.
