The picking of the fruit clusters is a key link of the mechanized harvesting of the corn, and the reduction of the picking loss plays an important role in ensuring the return of the grains to the warehouse and the safety of the grain. 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 corn growth, seeds tend to be mature, when encountering disasters such as strong wind and heavy rainfall, lodging easily occurs, the lodging which occurs at the moment has little influence on the corn yield, but plants are randomly distributed on the ground surface, so that the positions of the ears are lower than the effective ear picking height of the header, the header of the corn harvester cannot complete the ear picking action, a large amount of ears are remained at the bottom of the header, and the loss of falling to the ground is formed. 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 the harvesting of the lodging corns, the modes of reducing the operation speed of the harvester, reducing the height of the header and the like are generally adopted for picking the fruit clusters, on one hand, the harvesting efficiency is greatly reduced, and on the other hand, the loss of a large number of fruit clusters and seeds is also 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, it is necessary to invent a special lodging corn ear picking header aiming at different lodging forms of the corn, so as to solve the technical problem of picking lodging corn ears.
