Abstract

The invention discloses a soil nutrient extraction device and relates to the field of soil sample preprocessing. A lower blocking board arranged in a center shaft unit of the device is fixedly connected to the upper surface of a distance supporting board, an outer ring of a bearing is fixedly connected to the lower surface of the distance supporting board, an inner ring of the bearing is fixedly connected to the outer wall of a center shaft sleeve, the upper end of a center shaft spindle is fixedly connected with an upper blocking board, the lower end of the center shaft spindle sequentially penetrates through the lower blocking board, the distance supporting board and the center shaft sleeve to be fixedly connected with a center shaft supporting board, key grooves are arranged at the lower end of the center shaft sleeve, flat keys are disposed on the center shaft spindle, an elastic part is mounted between the upper blocking board and the lower blocking board, a main cylindrical gear is sleeved on the center shaft sleeve and is occluded with an auxiliary cylindrical gear, the edge of a cam is in contact with the upper surface of the center shaft supporting board, the cam is connected with a main conical gear through a transmission shaft, and the main conical gear is perpendicularly occluded with an auxiliary conical gear. The soil nutrient extraction device has a small covering area and is helpful to achieve vehicle-mounted operation.

Description

technical field [0001] The invention relates to the technical field of soil sample pretreatment, in particular to a soil nutrient extraction device and a working method thereof. Background technique [0002] my country's population accounts for 21% of the world's total population, but its arable land only accounts for 7% of the world's total arable land. With more people and less land, the trend of population increase and land decrease is irreversible in a short period of time, and food security has been severely challenged. The abundance and deficiency information of soil nutrients is an important basis for scientific fertilization and the realization of high-yield, high-quality, high-efficiency, ecology and safety in agriculture. The basic process of soil nutrient testing includes pretreatment process and analysis test process, and nutrient extraction is one of the important links of soil pretreatment. Improving the automation and instrumentation level of soil nutrient e...
