Abstract

The invention relates to the technical field of agricultural machinery, in particular to a cotton delivering pipeline illuminating device. The cotton delivering pipeline illuminating device comprises a support part and a parabolic lampshade arranged on the support part, wherein the parabolic lampshade comprises a first parabolic segment, a straight line segment and a second parabolic segment which are connected in sequence. Light rays emitted by a first lamp tube located on an intersection point of the first parabolic segment and the second parabolic segment are respectively reflected by the first parabolic segment and the second parabolic segment to form parallel light parallel to symmetric axes of parabolas, the parallel light is irradiated into a cotton delivering pipeline from different directions, simultaneously light rays emitted by a second lamp tube located at the straight line segment is reflected by the straight line segment and then is irradiated into the cotton delivering pipeline, the light rays enhance illumination intensity and illumination uniformity of the cotton delivering pipeline, and shadow inside the cotton delivering pipeline is avoided. In addition, a distance between the parabolic lampshade and the cotton delivering pipeline can be adjusted through the support part, the illumination intensity of the cotton delivering pipeline can be further adjusted, and a good daylighting environment is provided for detection and removal of cotton foreign fiber.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a lighting device for a cotton transportation pipeline. Background technique [0002] At present, the main principle of the cotton foreign fiber rejecting machine is to use a CCD high-speed camera or a visual sensor to scan the cotton fiber, and the scanning signal is sent to a computer or DSP system for image processing. When the foreign fiber is analyzed, an instruction is issued and it is turned on after a certain time delay. Jet valve, use the high-pressure airflow from the nozzle to remove foreign fibers. When using a CCD high-speed camera or a vision sensor to collect images of the cotton flow in the cotton delivery pipeline, the lighting device for the pipeline usually uses a lampshade bent by a steel plate to block the light emitted by the lamp tube into the cotton delivery pipeline. [0003] However, because the cotton in the cotton pipeline has a certain...
