Description

Cereal moisture normal position detection device Technical Field The utility model relates to the technical field of grain moisture detection, in particular to a grain moisture in-situ detection device. Background The agricultural planting in China is developed in the direction of standardized, mechanized and automatic planting, such as corn, wheat and rice, now and in the future. Biological detection of grains is an important link for distinguishing high-quality seeds, and the quality of the grains is also an important guarantee for guaranteeing mechanized harvesting. Taking corn as an example, the detection of corn moisture is a very important and precise processing link, the traditional determination of moisture content requires a large amount of corn seed test samples, equipment and manual operation time, in the actual corn breeding, the sampling number, sampling cost and the like of samples are limited in the measurement of corn seed moisture content in a grouting period due to the restriction of objective conditions such as the number of corn plants which can be planted per square meter and the effective test spike number due to the planting area of a new variety bred in the actual corn breeding, and the handheld online moisture original matter detection device is developed based on the problems that seeds are damaged, a large amount of sample sets are required and the like in the corn seed moisture detection in the current corn grouting period, and aims to reduce the sampling number in the corn breeding process, save the cost in the corn breeding process, provide moisture detection technical support for the corn breeding, facilitate the large-scale automatic rapid development of corn seed breeding and promote the promotion of corn mechanized process.
