Mechanical picking of lodging corn ears is a difficult point and a pain point which need to be solved urgently in corn harvesting. At the late stage of milk maturity to the early stage of wax maturity of maize growth, the seed grain tends to ripe, when calamities such as strong wind, heavy rainfall, very easily takes place to lodge, and lodging that takes place this moment is less to maize output influence, but the plant distributes in a jumble manner in the earth's surface, causes the ear position to be less than the effective ear of grain height of plucking of header, and the action is picked to the unable completion ear of maize picker header, leads to a large amount of ears to remain in the header bottom, forms and falls to the ground the loss. Research shows that the lodging rate is increased by 1%, and the loss rate of the mechanically harvested fruit ears is increased by 0.17% -0.28%. Meanwhile, lodging disturbs the ordered distribution state of the stalks with fixed row spacing and uniform plant spacing formed after the corn is planted, so that the harvester is difficult to align rows, the feeding of corn plants and other materials on the header is disordered, the loss of ears and grains is caused, and the header is blocked due to the overlarge feeding amount of instantaneous stalks, so that the harvesting efficiency is suddenly reduced.
At present, for harvesting of lodging corns, the modes of reducing the operation speed of a harvester, reducing the height of a header and the like are generally adopted for picking the fruit ears, on one hand, the harvesting efficiency is greatly reduced, and on the other hand, the loss of a large amount of fruit ears and grains is caused because the header is not suitable for the operation conditions of the lodging corns. Aiming at the severe lodging corn, related practitioners design lengthened grain lifters, a non-butt cutting table, a rotary rake tooth auxiliary feeding mechanism, a spiral auger type stem auxiliary lifting mechanism and the like to lift the position of lodging corn ears and feed the stems in the cutting table in an auxiliary manner. However, the mechanisms are improved on the basis of the cutting table of the traditional corn harvester, are limited by the cutting table structure, cannot completely adapt to different corn lodging forms, and have certain structural defects in operation.
In conclusion, for the heavily-lodging corn, the invention provides a special lodging corn ear picking header aiming at different lodging forms of the corn, and solves the technical problem of picking of lodging corn ears.
