Grain quality monitoring device with grain density measuring function and monitoring method

Abstract

The invention discloses a grain quality monitoring device with a grain density measuring function and a monitoring method. The grain quality monitoring device comprises a scraper elevator, a grain density measuring device and a grain collecting area, wherein the scraper type elevator is located on a harvester, and an in-place detection device, a photoelectric sensor and a scraper counting sensor are arranged on the scraper type elevator. The grain density measuring device is located on the harvester and connected with the scraper type elevator. The grain collecting area is located below the grain density measuring device. The grain quality monitoring method comprises grain density measurement and volume measurement of grain on the scraper. According to the invention, the volume of the grains can be measured online in real time, the real-time yield of the grains in an operation plot can be calculated, and a theoretical basis is provided for follow-up field fertility analysis of precision agriculture and further for variable seeding, fertilization and pesticide spraying.

Description

technical field [0001] The invention relates to a grain quality monitoring device and a monitoring method with a grain density measurement function, belonging to the technical field of agricultural machinery. Background technique [0002] Dynamic monitoring of grain quality during grain harvesting has always been a difficult point in agricultural production. At present, the grain flow sensors used to measure grain quality at home and abroad have certain deficiencies, mainly reflected in: the data measured by the impulse grain flow sensor is easily affected by the vibration of the fuselage, resulting in inaccurate yield information; The grain flow sensor is expensive, and γ-rays are potentially harmful to the human body; the weighing grain flow sensor system is limited by the use environment and is not suitable for grain harvesting machinery; the photoelectric grain flow sensor based on photoelectric diffuse reflection cannot characterize irregularities. 2D information on di...
