An agricultural implement including a toolbar, a plurality of row units connected to the toolbar, and a pneumatic seeding system. The pneumatic seeding system includes at least one storage tank configured for storing the particulate matter, a plurality of fluid lines fluidly interconnecting the at least one storage tank with each row unit of the plurality of row units, a fan fluidly connected to the at least one storage tank and to the plurality of fluid lines, and at least one pinch valve fluidly coupled to at least one fluid line of the plurality of fluid lines for adjustably balancing a respective airstream within the at least one fluid line of the plurality of fluid lines.

Flow splitting control valve for secondary header

A pressure gradient or differential in a product distribution line for conveying granular particulate material, including at least one of a seed or a fertilizer, in an air flow to an agricultural field consistently decreases as air speed and velocity in the product distribution line decreases until a critical air speed is reached. Below the critical air speed, the particulate material is susceptible to falling out of the air flow to potentially cause a blockage in the system. A control system efficiently determines an optimum operating velocity for an air flow that is above the critical air speed yet below a maximum air speed associated with inefficient operation. The control system retains the air flow setting in a data structure for later retrieval.

A pressure gradient or differential in a product distribution line for conveying granular particulate material, including at least one of seed or fertilizer, in an air flow to an agricultural field consistently decreases as air speed and velocity in the product distribution line decreases until a critical air speed is reached. Below the critical air speed, the particulate material is susceptible to falling out of the air flow to cause a blockage in the system. Pressure sensors arranged in the product distribution line are monitored for effectively controlling an air source producing the air flow. A diameter of the product distribution line increases between upstream and downstream locations for monitoring with greater sensitivity.

A product distribution control system for an agricultural system includes a controller having a memory and a processor. The controller is configured to receive a first signal indicative of a prescription map. The controller is further configured to determine a first parameter associated with operation of an air cart of the agricultural system based at least in part on the prescription map. The controller is further configured to determine at least one of a second parameter associated with operation of a work vehicle of the agricultural system based at least in part on the prescription map, and a third parameter associated with an implement of the agricultural system based at least in part on the prescription map, wherein the implement includes one or more row units. The controller is further configured to output, in response to determining the first parameter, a second signal indicative of an instruction to control a first element of the air cart based at least in part on the first parameter, output, in response to determining the second parameter, a third signal indicative of an instruction to control a second element of the work vehicle based at least in part on the second parameter, and output, in response to determining the third parameter, a fourth signal indicative of an instruction to control a third element of the implement based at least in part on the third parameter.

System and method for monitoring mass flow stability at variable air flow rates in an air seeder

A system and method are provided for quantifying a degree of discontinuity of material flow from a meter roller. A flowable particulate material is fed into a meter roller rotated at a constant speed while a camera takes pictures or images of the product dispensed from the roller. The images of the product taken by the camera are analyzed to determine the area of the image represented by the product. The areas of product within the images are then compared with one another to determine how continuous the area of product is in the respective frames. The area measurement for each image is calculated at a frame rate for the camera that, when compared to the flute frequency range of the roller, provides a frame per flute ratio that ensures all particles of product dispensed from the roller are captured in an image without overlap of product between frames.

A system and method are provided for quantifying a degree of discontinuity of material flow from a meter roller. In an exemplary embodiment, flowable particulate material is fed into a meter roller. The meter roller is then rotated one revolution, and the output from the meter roller is collected and measured. Next, the meter roller is rotated one revolution in discrete increments, each increment having a substantially equal rotational angle. The output from the meter roller is then collected and measured for each increment. Finally, the measurement for each increment is compared to the measurement for the one revolution to determine a statistical parameter indicative of flow rate discontinuity.
