Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a soil nitrogen content detection device. Background Art

[0002] Soil refers to a loose layer of material on the surface of the earth, composed of various granular minerals, organic matter, water, air and microorganisms, etc. It can grow plants. The soil contains a variety of elements required for the growth of crops. When planting certain crops, the soil is usually tested to see how much of the required elements it contains, so as to determine whether it is suitable for planting crops. When testing the soil, a part of the soil sample is usually taken and then tested. However, the soil taken out may contain some impurities, such as leaves and stones. Therefore, during the test process, the stones may touch the equipment and damage it, or these impurities may cause inaccurate detection.

[0003] A search was conducted on the above-mentioned issues and it was found that in the currently disclosed prior art, such as the publication number CN220357061U, a soil organic fertilizer nitrogen content detection device is proposed. The device puts soil into an inlet box and drops it into a sieve. Then a rolling wheel is arranged above the sieve, and the soil is rolled by moving the rolling wheel. The rolled soil sample passes through the sieve and falls below, and some impurities are retained on the sieve, thereby achieving a filtering effect. However, when the rolling wheel rolls the soil sample, if the soil sample contains larger pieces of stone, it may contact the stone when the rolling wheel moves. The rolling wheel pushes the stone forward. Due to its larger volume, the stone contacts more soil, thereby pushing the soil forward, and some soil may be pushed out through the impurity guide port on the side, thereby reducing the quality of the original soil sample and affecting subsequent test results.
