CLOSE LOOP CONTROL OF AN ILLUMINATION SOURCE BASED ON SAMPLE HEATING
20220046854 · 2022-02-17 ·

Crop is routed past a sample window on an agricultural combine harvester. Light it is impinged on the crop from an illumination source and reflected radiation is directed to a sensor. The output of the sensor is indicative of various constituents in the harvested crop. The illumination source is controlled based on the temperature proximate the crop sample.

Non-row sensitive forage harvester header

A non-row sensitive forage harvester header utilizes a single rotary transfer member to convey severed crop material from the forwardly positioned rotary cutting members to the feed rolls of the forage harvester. A fixed guide plate dislodges severed crop from the right cutting member to transfer the crop material to the left cutting member to convey the crop further rearwardly to the rotary transfer member. Additional fixed guide plates establish a flow path for the severed crop material and facilitate the movement of the severed crop from the left cutting member to the rotary transfer member and then to the feed rolls. A drive mechanism is provided to power the rotation of the cutting members and the rotary transfer member with a cutting disk on each cutting member being driven faster than the multiple crop engaging members also carried on the cutting members above the cutting disk.

20220304232 · 2022-09-29 ·

A method and an apparatus for determining a throughput of a harvesting machine. More specifically, a harvesting machine having a throughput sensor and electronic control device, the throughput sensor calibrated on part of a field with a crop stand of constant density to consider the influence of the rate of advancement and the rate of conveyance of the crop on the signal of the throughput sensor.

Drive mechanism control in an agricultural harvester
09723780 · 2017-08-08 · ·

An agricultural harvester has a controller operationally connected to at least the drive mechanism of header and the drive mechanism of the feedrolls to control these drive mechanisms. The controller successively executes a primary and a secondary synchronization procedure, wherein the primary synchronization procedure controls the header and feedroll drive mechanisms such that the header rotating speed and feedroll rotating speed are in a first predetermined ratio range; and the secondary synchronization procedure controls the header and feedroll drive mechanisms such that the header load and the feedroll load approach a second predetermined ratio.
