Soil sampler for sampling deep soil

Abstract

The present invention relates to a soil sampler for soil sampling, and in particular relates to a soil sampler capable of sampling deep soil. The soil sampler comprises a base box, a hollow drill bit, and a sampling tube; wherein a reducer is arranged inside the base box, the power shaft of the reducer is connected to a pedal pressure lever, the power output shaft of the reducer is in toothed connection with a spiral drill, the sampling tube is disposed inside the spiral drill, and the top of the spiral drill is in connection with the hollow drill bit. According to the present invention, based on the traditional soil sampler, by using screw and lever principles and separate design, the soil sampler both meets the needs of deep soil sampling, and is labor-saving and high efficient; and the pedal type deep soil sample is advantageous by being simple in structure, easy to assembly, convenient to use, and efficient in operation, having very important significance to the study of soil resource.

Description

technical field [0001] The invention relates to a soil fetching device for soil sampling, in particular to a soil fetching device capable of collecting deep soil. Background technique [0002] Agricultural soil is one of the high-yield, high-quality, and efficient resources for agricultural production. Changes in soil moisture and nutrients affect crop yields. In recent years, with the extensive use of chemical fertilizers, the nutrients in the soil surface have been seriously lost, and the nitrogen infiltrated with the ground water has changed the nutrient structure in the deep soil. At the same time, the study of deep soil moisture content and its change law can effectively use the moisture characteristics of the soil itself to conduct research on drought-resistant cultivation techniques and provide a basis for ensuring crop yields. [0003] The study of nutrient and water changes in deep soil has become an important aspect in agricultural production, but the acquisition ...

Problems solved by technology

At present, the soil drills used by Chinese scientific researchers are about 1m long, and can only take soil samples of about 1m in the soil layer. In arid areas, due to soil compaction and other reasons, it is difficult to drill below 40cm, which seriously reduces the efficiency of soil sampling.

At the same time, it consumes a lot of manpower and material resources

The long-term, large-scale, and blind use of traditional samplers consumes a lot of money and labor, so that the focus of scientific research is not on the laboratory, but a lot of waste on the collection of soil samples in the field

[0004] Traditionally, “Luoyang shovel” is used to collect deep soil samples, but due to improper soil sampling techniques, the sampling samples will be destroyed, and the lower pestle is completely used as power, so the labor efficiency is low. According to field statistics, 3m deep The soil layer takes about 1 hour on average

Moreover, the length of the soil sample taken out is difficult to control, because there is no standardized length, so it is not easy to carry during transportation
