  • Patent number: 10334775
    Abstract: A metering and mixing system of solid particulates for a rotary seed dispenser in agricultural equipment for sowing, wherein the rotary seed dispenser is mounted under a seed feeder. The rotary seed dispenser is driven at the bottom by a planter drive system, which provides rotation to a spinning disc provided with a number of calibrated orifices through which the seeds housed in the disc orifices fall on a given point of the agricultural equipment. The metering and mixing system of solid particulates includes a solid particulate feeder that is positioned between the seed feeder and the rotary seed dispenser.

  • Patent number: 8683930
    Abstract: An air seeder cart apparatus has a primary container assembly with a plurality of primary product containers, with primary fill hatches at tops thereof. An air distribution network comprises product conduits and primary metering devices that dispense agricultural products from each primary product container into one of the product conduits. A secondary product container is mounted on a side of the primary container assembly and has a secondary fill hatch much lower than the primary fill hatches, and a secondary metering mechanism dispenses product from the secondary product container into one of the product conduits. The secondary product container is convenient for receiving bagged agricultural products from a low truck bed. Unopened product bags may be stored on a grate inside the secondary product container so they will be available if required. Weighing of product in the container can be provided.

  • Publication number: 20120169495
    Abstract: A sectional control apparatus and method prompts the operator of an implement when the implement, or portion thereof, is traversing over land that has already been seeded and/or disturbed. The apparatus includes a GPS or GNSS receiver that communicates with a GPS or GNSS system and a controller that maps movement of the implement so that real-time positional data for the implement can be compared to the movement map. When the position of the implement, or portion thereof, is detected as moving over previously seeded and/or disturbed land, the controller activates an alert mechanism in the operator cab of the implement to notify the operator that sectional control, i.e., shutting down metering of product or raising the tool bar, needs to be implemented.

  • Publication number: 20030226484
    Abstract: A standardized receiver for bulk materials containers such as seeds for the quick and efficient loading of seed into a planter with bulk handling capability. Delivery mechanism associated with the receiver is disposed to accept materials discharged from the container after it has been placed on the planter frame and to transport such materials to the opener rows. A manifold of the mechanism is fitted with output pipe fixtures for the discharge of the seed to individual rows via flexible hose. The inlet of the manifold is on the top surface of the structure and aligned with the slidegate opening of the shipping container. Air pressure is created within the manifold by a fan assembly. Airflow exiting the manifold carries seed through the pipe fittings, into the hoses and on to the planter rows. The receiver mounts to the planter frame above the mechanism. The receiver conforms to the general dimensions of the bottom of a shipping container.

  • Patent number: 6112679
    Abstract: A liquid application unit for use on air seeders is provided which is cost-effective, has low maintenance and is highly reliable. This unit permits farmers to apply liquid substances, i.e. seed treatment substances to particulate material, namely seeds, just prior to the seed being inserted into the soil. The system uses an auger having two different pitches of flighting and/or different diameter flighting such that the volume available in between pitches of the flighting on the portion of the auger outboard of the orifice is greater than the volume available between the pitches inboard of the orifice. Chemicals are applied downstream of a sump area where the auger has either a larger pitch or larger diameter such that the volume available to the seed in the downstream area of the sump is greater. This will allow for better mixing action and minimize any effects on metering accuracy caused by build-up of chemicals on the flighting.

  • Patent number: 5937773
    Abstract: An applicator for dropping particulate material, such as fertilizer, to ground level, is formed from one or more hoppers capable of receiving particulate material, mounted on a wheeled main frame. Particles received from dispensing outlets depending from the lowermost section of each hopper are discharged into a horizontal delivery tube, within which is installed an auger shaft which carries helical flighting. Rotation of the auger shaft, driven by a drive system, causes the flighting to move the received particles to a particle outlet at a predetermined particle delivery rate. A control system, operatively engaged with the drive system, permits the user to determine the rate of auger shaft rotation, as dictated by the user's particle delivery rate requirements. Once particles reach the particle outlet, they are discharged into a conduit, through which they fall to ground level.
