Abstract: An apparatus for combining planting implements enables an operator of a tractor to use both a conventional cultivating implement and a conventional broadcasting implement simultaneously. The apparatus is rigidly affixed to a conventional cultivating implement and comprises a support frame, a pair of brackets, and a connection bar. In combination, the support frame, pair of brackets, and connection bar provide a three-point connection whereby a conventional broadcasting implement may be attached thereto, thus enabling an operator of a tractor to use both a conventional cultivating implement and a conventional broadcasting implement simultaneously. In operation, at least a portion of the conventional cultivating implement is disposed behind the conventional broadcasting implement when the conventional broadcasting implement is attached to the support frame, thereby allowing simultaneous cultivation and broadcasting of constituents.

Abstract: A seed orientation system for an agricultural planter includes a seed orientation coil assembly defining a helical pathway. As seed from a seed source enters the seed orientation coil assembly, air flow from an air source is directed toward the seed causing the seed to orient as the seed moves along the helical pathway toward a seed exit. Upon exiting the seed orientation coil assembly, the seed is deposited into the seed furrow with the seed tip-down and with germ of the seed facing an adjacent row. The seed orientation system may be retrofitted onto existing planter row units.

Abstract: An agricultural trench depth sensing system and method includes a light source (2002), a receiver (2003) and a sensor (2004). The light source directs light downwardly toward a trench previously opened in a soil surface. The receiver is disposed at an angle relative to the light source to receive reflected light. A sensor connected to the receiver senses a pattern of the reflected light. A monitoring system in communication with the sensor, generates a data frame containing triangulated line coordinates and intensity values of the reflected light indicative of a measured depth of the trench. The generated data frame may be associated with GPS coordinates for generating spatial maps and may be used to control operating parameters. The generated data frames may also identify relative soil moisture versus trench depth, or presence of dry topsoil or residue in the trench, or to identify seeds, seed spacing and seed depth.

Abstract: [Seed distribution device for an agricultural machine with a housing, a seed inlet, a perforated disc driven to transport the seeds and an outlet tube, the seeds being transported from a tank to the outlet tube by means of an air pressure difference, the air pressure difference being interrupted so that the seeds leave the disc to reach the outlet tube, the outlet tube comprising a first portion into which the seeds enter via an inlet, this first portion of the outlet tube being located inside the housing and being oriented so that the inlet is adjacent to the disc; the distribution device comprises a fairing element in which a first opening extending along a first fairing plane is carried out, and the fairing element covers the first portion of the outlet tube.

Abstract: A mobile agricultural machine includes a row unit having a furrow opener mounted to the row unit and configured to engage a surface of ground over which the mobile agricultural machine travels to open a furrow in the ground. A furrow closer is mounted to the row unit behind the furrow opener and configured to engage the surface of the ground to close the furrow. A furrow sensor system is mounted to the row unit and configured to sense characteristics relative to the furrow opened by the furrow opener and generate a sensor signal indicative of the characteristics. The mobile agricultural machine can further include a control system configured to determine a furrow quality metric corresponding to the furrow sensed by the furrow sensor system based on the sensor signal and generate an action signal to control an action of the mobile agricultural machine based on the furrow quality metric.

Abstract: A material introduction lock for a distribution machine for pneumatically conveying granular material in a conveying line adjoining a material introduction lock includes: an air inlet, a material conveying element, and a material infeed element, where a pneumatic conveying flow is supplied to the material conveying element via the air inlet, and the material infeed element is arranged between the material conveying element and the conveying line so that the granular material in the conveying line supplied via the material infeed element is conveyed in the conveying line by the pneumatic conveying flow supplied by the material conveying element. Further, the material infeed element includes a rinsing nozzle element which is connected to the air inlet and creates a film of air that sheathes the material infeed element from the inside, and the rinsing nozzle element is configured to reduce contact between the granular material and the material infeed element.

Abstract: An automated seed planter may include at least two vacuum cylinders which simultaneously and/or independently pick up and deliver seeds to a single tray. The vacuum cylinders may have a common rotational axis about which the vacuum cylinders rotate. The automated seed planter may include a plurality of vertical seed chutes which receive seeds therein. The vertical seed chutes have open upper and lower ends. A shutter assembly of the seed planter is associated with the lower ends of the vertical seed chutes. The shutter assembly is selectively opens and closes the lower ends of the seed chutes to plant the seeds on the tray. The automated seed planter may include a seed correction assembly including seed wells which receive seeds therein. The seed correction assembly selectively displaces one or more of the seeds from the seed wells to deliver the one or more seeds toward the tray for planting.

Abstract: An air flow calibration system for an agricultural system includes a controller configured to receive first sensor signals indicative of a set of upstream air pressures and second sensor signals indicative of downstream air pressures. The controller is also configured to iteratively determine a variance delta based on the pressures, compare the variance delta to a threshold value, and output a first output signal to decrease an air flow rate by a first amount until the variance delta is greater than the threshold value. The controller is configured to iteratively output a second output signal to increase the air flow rate by a second amount, determine the variance delta, and compare the variance delta to the threshold value until the variance delta is less than or equal to the threshold value. The controller is configured to determine a plugging condition is terminated, and store a calibration value.

Abstract: A first source of an electromagnetic signal is configured to illuminate or radiate the evaluation channel through which a series of particular seeds pass. For example, the electromagnetic signal comprises a pulse with at a primary reference phase and primary reference magnitude. A first receiver of the electromagnetic signal comprises a detector to determine or identify a first seed-related characteristic (e.g., first seed characteristic) based on an observed primary phase and an observed primary magnitude. For instance, a seed treatment device is configured to treat or spray discharged particular seed with a seed treatment based on the estimated characteristic, or to reject non-conforming seeds that do not meet seed specifications.

Abstract: An agricultural seeder (10) for research plots includes a front gang (21) of planting units (22) and a rear gang (23) of planting units (24) spaced a distance behind the front gang. Metering systems (14) are provided for metering seed to the planting units (22, 24) of the front and rear gangs (21, 23). A tripping system (27) is used to start and stop the seed metering systems (14) and to change seed between plots while planting. A programmable logic controller (28) is programmed with the distance between the front and rear gangs (21, 23) and is used to delay the tripping of the metering system (26) for the rear gang (23) relative to the metering system (25) for the front gang (21) until the seeder (10) has traveled the distance (L) between the front and rear gangs (21, 23). The delayed tripping for the rear gang (23) keeps the planted rows and alleyways created by the front gang planting units (22) laterally aligned with those created by the rear gang planting units (24).
