Rapid detection system for machine-harvested seed cotton water impurities in purchasing link

Abstract

The invention relates to a rapid detection system for machine-harvested seed cotton water impurities in a purchasing link. The rapid detection system structurally comprises a seed cotton large impurity cleaning device, a seed cotton sample box, a driving transmission device, a cotton pressing device, an image acquisition and processing device, a moisture regain detection device and a control cabinet, the seed cotton sample box consists of a positioning plate and a high-transmittance glass box; the weighing device is composed of a weighing sensor, a supporting plate and an electric push rod. The driving transmission device is composed of a roller, a conveying belt motor and a conveying belt. The cotton pressing device is composed of an electric push rod, a connecting rod, a connecting plateand a high-transmittance glass plate. The image collecting and processing device is composed of a camera, a light source, a detection sensor, an industrial personal computer, a touch screen and the like. The moisture regain detection device is composed of a moisture regain detection sensor, a signal line and a measurement controller. According to the rapid detection system for the water impurities of the machine-harvested seed cotton in the purchasing link, the impurity content and the moisture regain rate of the seed cotton after the large impurities are removed can be rapidly detected, thetechnical problems that in the purchasing process, the impurity content and the moisture regain rate of the seed cotton have complex detection procedure, low speed and the like are solved, and a real-time basis is provided for transaction settlement of the seed cotton in the purchasing process.

Description

technical field [0001] The invention relates to a rapid detection system for machine-harvested seed cotton in the purchasing process, which belongs to the field of agricultural machinery equipment. Background technique [0002] Cotton is an important production material and has an important impact on national economic and social development. In cotton production and sales, the sales price of cotton will decrease with the increase of impurity content, and moisture regain is an important factor affecting the processing quality of seed cotton. [0003] In the current cotton procurement process in my country, the impurity separation test is performed on the seed cotton samples to detect the impurity content after manual sampling, and the moisture regain of the seed cotton is generally measured manually by a hand-held moisture regain measuring instrument. Each link requires Manual participation, high labor intensity, low efficiency, and complicated procedures are not conducive to...

Problems solved by technology

[0003] In the current cotton procurement process in my country, the impurity separation test is performed on the seed cotton samples to detect the impurity content after manual sampling, and the moisture regain of the seed cotton is generally measured manually by a hand-held moisture regain measuring instrument. Each link requires Manual participation, high labor intensity, low efficiency, and complicated procedures are not conducive to the rapid detection and classification of seed cotton, which seriously affects the production and sales efficiency during the seed cotton purchase period
