The invention relates to a near-infrared spectrum based straw characteristic circulating on-line analysis device. The near-infrared spectrum based straw characteristic circulating on-line analysis device is characterized by comprising four conveyors which are connected end to end in turn; the first conveyor and the third conveyor comprise an upward inclined conveying section and a horizontal conveying section respectively, wherein the upward inclined conveying sections and the horizontal conveying sections are arranged along the conveying direction; the second conveyor and the fourth conveyor comprise an upward inclined conveying section respectively, wherein the upward inclined conveying sections are arranged along the conveying direction, the head end of each conveying section is located below the tail end of the horizontal conveying section of the previous conveyor, and the tail end of each conveying section is located above the head end of the upward inclined conveying section of the next conveyor; each side of a frame which is located at the top of every conveyor is fixedly connected with a lateral baffle plate; the lateral baffle plates of the four conveyors are connected together to form a feeding box; the top of the feeding box is horizontally and fixedly connected with transparent plate; the top of the first conveyor is fixedly connected with a feeding inlet; the top of the third conveyor is fixedly connected with a spectrometer. According to the near-infrared spectrum based straw characteristic circulating on-line analysis device, the four conveyors are connected end to end in a serial mode to form a closed circulating transfer device and accordingly the function of circulating on-line conveying and detection of straw materials is implemented.
Description
technical field [0001] The invention relates to an online analysis device, in particular to an online analysis device for straw characteristic circulation based on near-infrared spectroscopy. Background technique [0002] Straw is a multi-purpose renewable biological resource. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter. At the same time, straw is also a kind of roughage, with high crude fiber content (30% to 40%), and contains lignin and the like. my country is rich in crop straw resources, up to 700 million tons per year, and a large amount of straw is directly burned in the field to produce thick smoke, which not only pollutes the environment but also wastes resources. At present, straw is mainly used as feed, fuel, fertilizer and industrial raw materials through processing. [0003] The characteristics of straw chemical composition and thermochemical engin...
