摘要： A system for electronically pulsing agricultural product with seed includes a seed transport mechanism affixed to a seed planter row unit. A seed sensing device senses dispensation of the seed from the seed transport mechanism. An agricultural product conduit dispenses agricultural products into the seed transport mechanism to provide dispensing of the products with the seed as the seed and product exit the seed transport mechanism. A control interface electronic system dispenses a particular quantity of product with the seed in the seed transport mechanism. A pulsing valve dispenses products from the conduit when the seed sensing device senses the dispensation of the seed. A seed release speed is provided which is proportional to the ground speed of the seed planter row unit to minimize seed tumbling and optimize accurate placement of seed and product at varying ground speeds of the row unit.

摘要： A system for dispensing agricultural products includes an agricultural product container having a memory circuit associated therewith for storing data, the stored data including data unique to the container and the quantity of material dispensed including specific rates of application. An application rate meter device is operatively connected to the agricultural product container and is configured to dispense the agricultural product from the agricultural product container. Precision placement equipment includes a placement tube assembly operatively connected to the application rate meter device to place the agricultural products in the desired locations for efficient activity of the agricultural product. Each placement tube assembly is mounted between depth wheels of a depth control wheel assembly of a planter for placement of product in-furrow between the depth wheels.

摘要： A system for electronically pulsing agricultural product with seed. A seed transport mechanism is affixed to a seed planter row unit having a seed metering system, operating at a high speed configured to dispense seed. The seed transport mechanism includes a conduit for introducing agricultural product with seed. The agricultural product is configured to be introduced with the seed after output from the seed metering system. A seed sensing device is operably connected to the seed transport mechanism and configured to sense a dispensation of the seed from the seed transport mechanism. The agricultural product conduit is configured to dispense agricultural products into the seed transport mechanism to provide dispensing of the agricultural products with the seed as the seed and agricultural product exit the seed transport mechanism. The agricultural products comprise chemical granules. A control interface electronic system is operably connected to an agricultural product metering system and the agricultural product conduit, the control interface electronic system being configured to dispense a particular quantity of agricultural product with the seed in the seed transport mechanism. An electrical pulsing valve is operably coupled to the agricultural product conduit and the control interface electronic system, being configured to open to dispense chemical granule agricultural products from the agricultural product conduit when the seed sensing device senses the dispensation of the seed. The seed transport mechanism is configured to provide a seed release speed at which the seed and agricultural product exit the seed transport mechanism, the seed release speed being varied in a manner proportional to the variation in the ground speed of the seed planter row unit to minimize seed tumbling to optimize accurate placement of seed and chemical granule agricultural product at varying ground speeds of the seed planter row unit. In the various embodiments, the agricultural product is directed away from moving parts after the seed leaves the seed metering system of the seed planter row unit.

摘要： A system for dispensing agricultural products includes at least one source of agricultural product; at least one agricultural product tube, a seed sensing device, a metering system, and a sensor assembly. At least one agricultural product tube is connected to the source of agricultural product. The seed sensing device is configured to control the delivery of the agricultural product. The metering system is coupled to at least one agricultural product tube and to the seed sensing device and is configured to synchronize the placement of agricultural product relative to the placement of seed. A sensor assembly includes a signal conditioning circuit. The signal conditioning circuit is configured to provide an output signal representing an indication of the presence of the agricultural product. At least one seed for use in determining the synchronized placement of seed and the agricultural product in correct proximity with one another in a seed furrow.
