Problems solved by technology

A disadvantage of the known ear elevators with support rods made of spring steel is that the support rods can be deflected downwards by the resistance of the front end penetrating the ground, i.e. into the ground, which further increases the resistance
In such cases, the ear elevator is usually damaged so badly that it must be replaced

Embodiment Construction

[0047] Figures 1 a and 1 b show a first embodiment of the ear elevator according to the invention, wherein Figure 1 a shows a side view and Figure 1 b shows a perspective view. The ear elevator for crops according to the invention has a support rod 5 which extends in the main direction of extension X. The main direction of extension X is indicated by an arrow in FIG. 1a. When the ear elevator is installed according to the invention, the main direction of extension X corresponds to the direction of travel of the harvester. It can be seen in the perspective view of FIG. 1 b that the support rod 5 is made of a flat material, the second direction of extension Y being oriented orthogonally to the main direction of extension X. In FIG. In FIG. 1 a, the second direction of extension Y points in the drawing plane. A third spatial direction perpendicular to the main direction of extension X and the second direction of extension Y is designated by the reference symbol Z, wherein the t...

Abstract

The invention relates to a crop lifter for harvested crops, comprising a support bar, said support bar extending in a main direction of extent and having a fastening portion, a center portion and a skid portion arranged one after the other in the main direction of extent.

Description

technical field [0001] The following disclosure relates to an ear elevator for crops with a support bar The support rod extends in the main extension direction and has a fastening section, an intermediate section and a sliding section arranged one after the other in the main extension direction. Background technique [0002] Known cutting systems for harvesters have so-called cutter bars Harvesting fingers arranged along the cutter bar The harvesting fingers guide the cutter bar and form secondary blades for the cutting blades, which are mounted on a reciprocating cutter bar (Messerbalken). To be able to safely cut kinked or fallen stalks, use the ear elevator to lift the stalks. Such ear elevators comprise a support bar, the fastening part of which can be fixed to the cutter bar and, if necessary, supported by holders on the ends of the cutting fingers. Depending on the direction of travel of the harvester, the fastening portion forms the rear end of the support bar,...
