  • Patent number: 8931423
    Abstract: A soil opener comprises a tip attached to or integral with a body. The tip includes furrowing prow for cutting a furrow in the soil surface, a protrusion on the underside of the tip for cutting a trench within the furrow, and a seed distributor for depositing seeds within the furrow in laterally displaced seed rows. The body includes a seed passage for directing a seed stream to the seed distributor, a primary fertilizer passage for depositing a primary fertilizer stream, and a secondary fertilizer passage for depositing a secondary fertilizer. As the soil opener is moved across the soil surface, the body opener deposits primary fertilizer in the vicinity of the seed rows, and secondary fertilizer between the seed rows in a trench slightly below the surface of the seeds.

  • Patent number: 8291844
    Abstract: Aspects of the present invention involve an extension adapted to extend from a planter, such as the seed tube portion of the planter, into a seed furrow in order to engage seeds being deposited therein, where such engagement may involve deflecting the seeds toward the vertex region of the furrow and/or firming the seeds in the furrow. The extension includes or supports a fluid distribution arrangement such as a hose or the like, which may be separate or integral with the liquid supply hose of a planter. The fluid distribution arrangement is adapted to supply fluid, such as liquid fertilizer, insecticide, water, etc., to the furrow. A valve is provided in the fluid flow path in the region of the fluid distribution arrangement to control the distribution of fluid to the furrow. The valve may be a check valve that allows fluid flow therethrough when fluid pressure exceeds a value such that the valve opens, and prevents fluid flow when the pressure decreases below the valve activation pressure.

Suitable controls enable the operator to mix liquid root stimulator solution within a storage tank, and then pump it into the ground through the probe. A motor-driven air compressor controls a pneumatic holding tank to store pressurized air. The multi-segmented probe has a rigid, upper segment that receives liquid through a check valve, an intermediate segment receiving high pressure air, and a lowermost section extending downwardly from a foot plate and terminating in a hardened point. Output orifices defined in the tip deliver air or solution subterraneously. A controller circuit times an injection cycle upon actuation of a probe-mounted switch by actuating a solenoid valve for metered fluid injection. When the injection cycle completes, a manual valve on the probe can be opened for aeration.

    Abstract: A field planting system for use in conjunction with large span and wheel tower irrigation apparatus to place seed in a field across a number of rows simultaneously. Seed is suspended uniformly in a gel solution and injected into a stream of carrier water. The seeds, suspended in water, travel in piping separate from irrigation piping to a manifold suspended from the overhead span section. Each manifold distributes seed and carrier water to a plurality of drop tubes. A tube valve locate in each drop tube is closed to permit the manifold to be charged with seeds and water under pressure. Once the manifold is charged, the tube valves open simultaneously and the water and seed discharges from the manifold through drop tubes to a planting shoe. The planting shoe includes a forward nozzle to emit a high pressure stream of water to excavate a small trench or furrow into which the seed is dispensed.
