Online detecting device and online detecting method for synchronous belt type corn kernel breaking rate

Abstract

The invention relates to an online detecting device and online detecting method for synchronous belt type corn kernel breaking rate. The device comprises: a detecting box, a blanking unit, a mechanismexecuting unit and a detecting unit, wherein the blanking unit comprises a blanking slot and a blanking chute, the mechanism executing unit is in a synchronous belt transmission structure, and the detecting unit comprises a CCD industrial camera, a processing chip, and an in-vehicle control and display terminal. Each of the units cooperates with each other to transmit data in real time to ensurethe smooth online detection of the corn kernel breaking rate. The method comprises the following steps: the CCD industrial camera collects corn kernel images and outputs the images to the processing chip for processing to identify broken corn kernels, and the in-vehicle control and display terminal calculates a corn kernel breaking rate. The device provided by the invention is small in size, simple and reliable in structure, convenient to carry, easy to be installed with the combine harvester grain box, high in clarity of images acquired by the CCD industrial camera, simple and efficient in algorithm, and fast in image data information processing speed, so that advantages of high detection efficiency, strong reliability and high precision are obtained.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a synchronous belt type on-line detection device and method for corn grain breakage rate. Background technique [0002] Corn is one of the three major food crops in the world. Corn is planted in a wide range in my country. Corn is not only an important food resource, but also an important chemical and feed raw material with high economic value. However, due to the machinery of corn combine harvesters in my country, it is easy to cause The crushing of corn kernels increases the average crushing rate of corn and reduces the quality of corn by 1 to 2 grades, which cannot meet the overall demand for corn yield and quality in my country. [0003] The broken rate of corn kernels is one of the important assessment indicators for measuring corn combine harvesters. The broken rate directly reflects the harvest quality and performance of the agricultural machinery. At the same time, the b...
