In one embodiment, an electronic system comprises a display device to display data and processing logic coupled to the display device. The processing logic is configured to determine a duty cycle of at least one sensor for sensing flow of a product or particle through a product or particle line of an agricultural implement and to determine an amount of product or particles flowing through a line of the agricultural implement based on the duty cycle of the at least one sensor.

A sowing machine and a method for separating and spreading granular material, such as seed or the like, are described, where the material is supplied by way of conveying airflows from a central container to metering devices via conveying ducts respectively associated with them. Furthermore, the material supplied in the conveying ducts is separated from the respective conveying airflow and the resulting discharge airflows are supplied via discharge air ducts to the respectively associated metering devices which are thus pressurized. Furthermore, the metering chambers are pressurized by way of supply airflows via supply ducts respectively associated with the former. The material is separated in the metering chambers by way of separating disks. Due to the fact that the supply airflows and the discharge airflows are fed into the metering chambers separately from one another, the required pressure level in the separating devices that generate the discharge airflows and thereby also the pressure level in the granular material dispensed from the separating devices to the metering devices can be reduced. This improves the separating quality of the metering devices.

A device for distributing bulk material, such as seed material, includes a flow path having at least one conduit for conveying the bulk material from a bulk material source towards an agricultural area, and a blockage detection device in the flow path. The blockage detection device includes at least one sensor, which is mounted to the outside of the line and is configured to register mechanical vibrations of the line, as well as an evaluation unit in signal communication with the sensor, which is configured to detect a blockage as a function of the registered mechanical vibration. A method for detecting a blockage includes a sensor that identifies blockage as a function of the detected mechanical vibration.

The disclosed pneumatic seed meters for small seeds and fine grains may include a rotational disk with a plurality of radially disposed holes. The holes may define a seed path when the rotational disk rotates. The seed meters may also include a sealing structure that is positioned and configured to inhibit seed leakage from the seed meter. The sealing structure may define a seed containment chamber. Various other related methods, systems, and devices are also disclosed.

The invention provides a pneumatic conveying system having a series of supply lines with at least portions of the lines being wear resistant to extend the useful lifespan of an agricultural product delivery applicator. The wear resistant supply line(s) may be made from a hard material and have a curve(s) defined by angled or mitered segments that are welded or otherwise joined to collectively provide the curve(s) The wear resistant supply lines may be at least partially reinforced by way of, for example, welded or other build up wear resistant material(s) at high wear zones of the supply lines.

A seed distributor evenly delivers seed from a bulk seed tank via hoses to seed bins on row planter units. The distributor has a circular chamber for receiving seeds from the seed tank. An internal cone in the distributor deposits the seeds 360° around the chamber. Seed tubes extend through the sidewall of the chamber. Pressurized air is introduced into the chamber and picks up seeds on the floor of the chamber and pass through the seed tubes for delivery by the hoses to the bins. The distributor may also include air tubes aligned with the seed tubes to further assure even distribution of seeds to the bins.

A seed meter for an agricultural planter in which the seed disc is rotatably mounted within a seed meter housing. As the seed disc rotates, the apertures in the disc rotate along a seed aperture path through a horizontally adjacent seed pool area. The seed disc includes cavities disposed along the seed aperture path to agitate the seeds in the seed pool area. A singulator having multiple co-planar singulator surfaces is biased against the seed side surface of the seed disc.

An agricultural product delivery applicator for delivering particulate product to a field and including a pneumatic conveying system. The pneumatic conveying system includes an airflow source to provide an airflow, first and second delivery lines operably connected to the airflow source and to a supply compartment. Each delivery line includes a respective supply line and a respective plurality of distribution lines. The pneumatic conveying system further includes first and second distributors coupling the respective supply line with the respective plurality of distribution lines, a first mounting plate coupled to the first distributor and having a first identifier, a second mounting plate coupled to the second distributor and having a second identifier, a first motor having a relation with the first identifier, and a second motor having a relation to the second identifier.

A variable rate air metering system is provided. The system includes seed meter cartridges, each having a housing, a meter wheel, and a variable speed electric motor operatively connected to the seed meter cartridge. The seed meter cartridges provide flowable material to distribution manifolds, which are configured to distribute flowable material to multiple row outputs for deposition into a field. A control system is configured to control operation of the distribution manifolds for enabling/disabling dispersement of flowable material to row units. The control system is also configured to adjust the dispersement rate of flowable material by the seed meter cartridges in association with the opening/disabling the dispersement of flowable material to row outputs.

The invention relates to a distributor (10) for granular material, having a distributor head (14), which is designed to divide up an air-material main flow supplied through a main conveying line (12) to the distributor head (14) into a plurality of air-material individual flows, and at least one return device (16), which comprises a movable deflecting element (36), which is designed, in a delivery position, to supply an air-material individual flow flowing into an inflow region (26) of the return device (16) to a delivery region (28), connected to a delivery line (18), of the return device (16) and, in a shut-off position, to direct an air-material individual flow flowing into the inflow region (26) of the return device (16) via a return line (30) of the return device (16) to a return region (32), connected to the main conveying line (12), of the return device (16).
