Bean seed grain size measuring instrument and measuring method

Abstract

The invention discloses a bean seed grain shape size measurer and a measuring method, for ensuring bean seed grain length and width measurement precision. The bean seed grain shape size measurer comprises a base, a column, an object stage, a clamping assembly and an amplifying assembly, wherein the column is arranged at the top of the base; the lower part of the column is provided with a first mounting block; the object stage is hinged on the first mounting block; the top part of the object stage is provided with a sliding groove; a sliding plate is arranged in the sliding groove in a sliding mode; the top part of the sliding plate is provided with the clamping assembly for clamping bean seed grains; the top part of a first clamping plate is provided with a first laser lamp; the top part of a second clamping plate is provided with a second laser lamp; the first laser lamp and the second laser lamp can emit light beams of different colors; a second mounting block located on the column is arranged above the first mounting block; a first size plate is hinged on the second mounting block; a first network scale line for measuring the length and the width of a grain is arranged on the first size plate; and the amplifying assembly is arranged above the first size plate. Length and width size measurement on the grain can be realized, and the measurement precision is high.

Description

technical field [0001] The invention relates to the technical field of grain shape measurement, in particular to a measuring instrument and a measuring method for accurately measuring the grain size of bean seeds. Background technique [0002] Bean crops are rich in varieties and are important grain and oil crops and economic crops. Grain length and grain width are important morphological characteristics of bean crops and an important index for evaluating the appearance quality, yield and quality level of bean varieties. The grain length and width are not only related to the germination ability and stress resistance characteristics of seeds, but also directly affect the survival ability of seedlings and the yield level of crops. Therefore, by measuring grain length and grain width, screening for bean seeds with good morphology and high quality is a prerequisite for improving seed storage life, germination efficiency, and ensuring neat emergence. Due to the rich varieties a...
