A corn harvester is an agricultural machine for picking and collecting corn ears, which picks the ears on corn stalks by using an ear header at the front end of a vehicle body and conveys the picked corn ears to a large elevator. The ear picking mechanism of the corn ear header is often provided with an adjustable gap between ear picking rollers according to the actual working condition, namely the type of corn to be harvested, and correspondingly, the gap between a pair of ear picking plates also needs to be adjusted accordingly. In addition, the ear picking mechanism of the existing corn ear header generally adopts a left long seedling pulling chain and a right long seedling pulling chain to carry out seedling pulling and feeding on corn stalks and convey corn ears picked by the ear picking rollers to an inlet of a large lift conveyer.
In the existing ear picking mechanism of the corn ear header, the clearance between a pair of ear picking plates is often manually adjusted, and once the clearance is adjusted, the header shield needs to be opened, so that time and labor are wasted; secondly, the adjustment of the clearance between the snapping plates needs to be stopped and the operation is stopped, and the dynamic adjustment can not be realized according to the real-time situation of the corn to be harvested.
