Description

Technical Field

[0001] The invention relates to a method and device for quickly evaluating impurities in a seed cotton purchasing process, which are used to solve the technical problem of slow detection speed of impurity content in the purchasing process and belong to the field of agricultural machinery and equipment. Background Art

[0002] Cotton is an important production material and has a significant impact on the national economy and social development. In the production and sales of cotton, the sales price of cotton will decrease with the increase of impurity content. At the same time, the size of the impurity rate also affects the processing flow of cotton, and even directly affects the cotton ginning and spinning effects, and ultimately affects the quality of woven products.

[0003] The current cotton impurity detection technology in my country is relatively backward. At present, the cotton purchasing process mainly uses a cotton impurity analyzer to perform an impurity separation test on the seed cotton sample after manual sampling to detect the impurity content. Each link requires manual participation, which is labor-intensive, inefficient, and complicated. It is not conducive to the rapid detection and grading of seed cotton, and seriously affects the production and sales efficiency during the seed cotton purchase. In the early cotton impurity detection standards, the cotton impurity detection method is the Xilai analyzer. The domestic methods for cotton impurity detection mainly include manual sorting, raw cotton impurity analyzer, and large-capacity cotton fiber tester. Manual sorting has high cost and low efficiency, and the raw cotton impurity analyzer has complicated procedures. The large-capacity cotton fiber tester has high efficiency and high precision, but it is expensive and the detection object is lint cotton, which is not suitable for the seed cotton purchase link. CN201720052812.X discloses a raw cotton impurity analyzer, including a control device, a weighing device, and a cotton feeding device, which reduces the labor intensity of manual labor and improves the automation level and detection efficiency. CN201721351825.3 discloses a cotton impurity detection device based on reflection and transmission hyperspectral imaging, including a sensor optical module, a light source module, and a sampling module. Different light sources emit photons of different wavelengths to the cotton on the stage. The photons form a hyperspectral image of the impurities after reflection, absorption or projection. The detection accuracy is high and the classification and identification effect of impurities is obvious, but the speed is slow and not suitable for use in the seed cotton purchase link. In summary, it is necessary to design a set of seed cotton impurity online detection devices and rapid evaluation methods suitable for the purchase link, so as to realize the rapid evaluation of seed cotton impurities during the purchase process, improve the degree of automation, reduce the manufacturing cost of the detection device, reduce labor intensity, and improve detection efficiency. Summary of the invention
