Corn Header Longitudinal Vertical Guidance, Cutting Device Study

Corn harvester is currently widespread in China the following issues: the poor adaptability of maize spaced; the form of a single corn straw, corn stalks can not meet the requirements of various forms; power consumption, promote the use of difficult, to a certain extent, restricted the harvest of maize Machine development.To meet the diverse use of corn stalks (used as feed, fuel, fertilizer, etc.) the status quo, to require the corn combine harvester corn stalks after snapping in order. Therefore, the need to bring ear of corn cut from the roots and transported to the standing corn machine side, and then back above the conveyor, is conducive to snapping, straw chopping and other parts of the configuration, which meet the diverse requirements of the use of corn stalks.The above problems, Henan University of Science and Technology designed a new type of corn header, with the ear of corn can be cut off from the roots, and lateral standing corn stalks with the function of transport, which can be ordered with a vertical transmission of Corn, the post-sequence Harvesting and straw diversity processing (breaking land, chopped recycling, etc.) to create favorable conditions, which meet the diverse requirements straw.The topics to guide the device for longitudinal cutting table object to cut the number and angle of cut stubble as an index of the crank cutter knife cutting speed on cutting performance of law; to the tooth with the allocation of the active call chain sprocket Wo speed test factors, corn stalk was allocated teeth resulting from the actual allocation of inclination to live as an indicator of the dial Wo chain driving wheel chain speed and angle of the relationship between corn stalk; to guide the device vertical and horizontal transmission gear dial dial The distance between the teeth as the experimental parameters, horizontal transmission success rate index, of the tooth side from the impact on the delivery success rate; and a longitudinal study on the maize plants to guide institutions forward, backward adaptation. The corn harvester cutter device and vertical guidance devices provide a basis for optimal design.
