Abstract:

A seeding machine having a plurality of row units and a processing circuit. Each of the row units have a seed metering device, a seed placement device and a sensor suitable to detect a parameter related to seed placement. The seed metering device includes a metering member providing a metering action to a plurality of seeds. The seed placement device receives the seeds from the seed metering device. A seed meter drive controller receives an index signal from the sensor on the row unit as well as a reference pulse signal. The processing signal of the drive controllers compares the index signal to the reference signal. Each drive controller is selectively programmable to control an associated motor of the meter drive to produce a desired relationship between the row unit index signal and the reference signal thereby synchronizing the seed placement among two or more rows. block diagram illustrating an alternative arrangement of the meter drive and control system components.

US Classification:

700231, 701 50

Abstract:

A seeding apparatus and a method is disclosed in which a seed spacing variability value is determined and displayed to the operator during a planting operation. Any method of determining variability among a set of data can be used to determine the seed spacing variability value. Three examples are shown: standard deviation; coefficient of variation; and coefficient of uniformity. Data can be stored for later comparison with harvest yield data to determine the effects of seed spacing on yield.

A01B 63/24

US Classification:

172 4, 172315

Abstract:

A supplemental downforce system is shown for a ground working implement having a frame and a plurality of ground engaging row units movably mounted to the frame for up and down movement relative to the frame. The downforce system includes at least one actuator between the frame and each row unit to apply an up or down force to each row unit. The actuators are assigned to one group of at least two groups of actuators. A control system controls the down force applied by each group of actuators separately so that each group of actuators is given the amount of supplemental down force that group of row units needs. In a closed loop feedback system, at least one row unit in each group of row units is equipped with a load sensor so that feed back of the soil reaction force on the row unit is supplied to the control system.

International Classification:

A01C 7/10

Abstract:

A plurality of different controllers on an agricultural machine are time synchronized. A positioning system detects a geographic location and a timestamp, which is indicative of a time when the geographic location was sensed, is applied to the geographic location. A first controller, that identifies an action to be taken based upon a location of the agricultural machine and a speed of the agricultural machine, and also based on a geographic location of where the action is to be taken, generates a future timestamp indicating a future time at which the action is to be taken. An action identifier (that identifies the action) and the future timestamp is sent to an actuator controller that controls an actuator to take the action. The actuator controller identifies an actuator delay corresponding to the actuator and controls the actuator to take the action at a time identified in the future timestamp based upon the future timestamp, a current time, and the actuator delay.

A01C 7/08
G01F 1/00

Abstract:

An example agricultural machine comprises a material distribution system that includes a material distribution line configured to convey particulate material to a component. The agricultural machine comprises a sensing system that includes a first sensor configured to generate a first sensor signal indicative of a measure of a flow of the particulate material in the material distribution line, a second sensor configured to generate a second sensor signal indicative of a measure of the flow of the particulate material in the material distribution line, and a correlation generation component configured to receive indications of the first and second sensor signals and to generate a correlation metric that represents a correlation between the first and second sensor signals. In one example, the correlation metric is applied to a sensor signal from a second material distribution line to determine a flow rate in the second material distribution line.
