Abstract

This technical disclosure relates to a scheme for visual indication of ground terrain through combination of bar graphs based on header height sensors. The proposed solution has atleast two header height sensors mounted under cutter bar of header attached to harvester, microcontroller, and bar graph indicators. Signal from header height sensors will be processed in microcontroller to determine ground profile and the output from microcontroller algorithm will drive the 3 bar graphs representing the ground terrain profile. This bar graph visual indicator gives operator the feedback about ground terrain profile.

Abstract:

The proposed solution has atleast two header height sensors mounted under cutter bar of header attached to harvester, microcontroller, and bar graph indicators.

This bar graph visual indicator gives operator the feedback about ground terrain profile.

Background:

During harvesting operation, operator adjusts header height based on desired cut length of crop from ground considering productivity and judgment for the slope / gradient. Operator adjusts the header manually with aid of hydraulic valves from the cabin. In many cases the ground terrain may not remain consistent at the time of crop harvesting and over the time gradient changes could result into loss of productivity. With an open cabin structure it poses further challenges for operator

to judge the field gradients. In worst case situations it could lead to digging the earth by the header. The behavior could be predominantly seen in low lying crops like soybeans. The solution is trying to close the loop for operator by providing a visual indicator corresponding to the changes in ground terrain.

Sensor Mounting:

Header height sensor can be selected from rotary potentiometer or any other sensors.This sensor will be attached to a spring loaded pivot arm assembly suspended from the base of cutter bar on t...
