Abstract

This invention reveals a corn harvester header comprising: multiple harvesting units placed adjacently among them, where each of said harvesting units has a central slot through where a maize plant is processed to separate the ears from the stalks; multiple crop divisors, each placed between two adjacent harvesting units; and multiple frontal devices, each place in front of and between two adjacent harvesting units; where each one of said multiple frontal devices comprise: a pair of guiding elements, where the guiding element is selected from a group of: chain or belt; two or more wheels; and a support; where the guiding element is placed around said two or more wheels; where one of the two or more wheels drives the spin of the guiding element, where the tangential speed of the guiding element is configured according to the distance between the plants in the crop; and where an opening greater that the harvesting slot is created.

Claims5

Dependent claims

Lifting assembly for a corn harvester header, wherein a corn header comprises a plurality of lifting assemblies, one next to the other, each assembly having a chassis with a pair of lifting chains mounted thereon, which are composed of a plurality of bonds between which there are, at a proper distance from each other, conveying bonds for the conveyance of the harvested crop towards a collector and hopper set of the harvester, the chains being arranged adjacently to each other, such that they form in the middle a channel for conveying said crop towards said collector and hopper set of the harvester, each chain being rotationally mounted around cogwheels at least one of which is the driving one, and the lifting assembly being characterized in that:

said chassis has two parallel arms, wherein each one of them has each of said lifting chains mounted thereon, each arm having a front portion which faces said crops during harvest and said front portions are tilted outwards, progressively farther away from each other, so as to form a wider opening than said conveying channel, said chains having a parallel length where the chains are extended in parallel relation one to the other along said conveying channel and a tilted length where the chains are tilted, progressively farther away from each other, on said front portions of the chassis arms, each of said arms having a deflecting support between said parallel length and said tilted length of the chains.
