  • Combine harvester for seed production and multiplication of grains with automatic cleaning function
    Patent number: 12324373
    Abstract: A combine harvester for seed production and multiplication of grains with automatic cleaning function includes a machine body. The machine body includes a header for harvesting grain plants, and a cleaning device mounted on the header for cleaning the header. The cleaning device includes a controller connected to both a blowing mechanism and a material collecting box mechanism via signals. The blowing mechanism is employed to allow for automatic cleaning of the header without the need to shut down the machine; and seeds and other residues blown out during the cleaning can be recovered through the material collecting box mechanism, avoiding waste.

  • AUTOMATIC ROW-GUIDING METHOD FOR MAIZE COMBINE HARVESTER BASED ON SITUATION OF MISSING PLANTS
    Publication number: 20230072236
    Abstract: Disclosed is an automatic row-guiding method for maize combine harvester based on the situation of missing plants, comprising: S1, guiding calculation of missing plants according to a traveling speed of a harvester and output values of left and right detecting sensors; and S2, performing guiding calculation of missing plants if there is a situation of missing plant, obtaining a first target turning angle of an electric steering wheel; or obtaining a second target turning angle according to the output values of the left and right detecting sensors if there is no situation of missing plant, then adjusting the steering wheel in terms of controlling direction, and finally, realizing automatic row-guiding of the combine harvester.
