Foldable soil nutrient detector based on soil scraping

Abstract

The invention relates to the technical field of detection equipment, in particular to a foldable soil nutrient detector based on soil scraping. The foldable soil nutrient detector based on soil scraping comprises a detection box and a detection device arranged on the lower side of the detection box, and the detection device comprises a fixed detection frame, a rotating probe scraping device, a detection mechanism and a driving mechanism. In the overturning process of the rotating probe scraping device, the side face of the fixed block is scraped, soil on the side face of the fixed block is removed, meanwhile, in the overturning process of the rotating probe scraping device, an inner scraping mechanism is used for scraping the side wall of a push rod, soil on a detection mechanism is reduced, corrosion of the soil to a metal detection head is avoided, the rotating probe scraping devices are inserted into the soil, so that the metal probe arranged between the two rotating probe scraping devices is not in direct contact with the soil, the metal probe is prevented from being in contact with stones in the soil when being inserted into the soil, and normal use of the metal probe is guaranteed.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a foldable soil nutrient detector based on soil scraping. Background technique [0002] The soil detector is mainly used to detect moisture, salinity, ph value, total nitrogen, ammonium nitrogen, alkaline nitrogen, available phosphorus, available potassium, calcium magnesium, boron, etc. in the soil and test the nitrogen, phosphorus, and potassium content in fertilizers. It greatly alleviates the needs of farmers all over the country for soil testing and formula fertilization, and at the same time provides a reliable basis for fertilizer production enterprises to achieve specialization, systematization, informationization, and dataization. It is the first choice for soil testing and formula fertilization in the agricultural sector; [0003] When using the soil nutrient analyzer used on site, the metal detection head of the analyzer will be inserted into the soil, but ...

AI Technical Summary

Problems solved by technology

[0003] When using the soil nutrient analyzer used in the field, the metal detection head of the analyzer will be inserted into the soil, but the situation in the soil is unknown, and it is easy to cause the metal detection head to collide with the stone, resulting in damage to the metal detection head. And when the metal detector head is pulled out from the soil, soil will adhere to the metal head. If the adhered soil sticks to the metal head for a long time, it will corrode the metal head and cause damage to the metal head.
