摘要： A product on demand nozzle assembly includes a chamber at least partially defined by an external wall and an array of vertically spaced nozzles. Each nozzle has an air inlet, an air and entrained product outlet extending from the external wall, and an entrainment zone between the air inlet and the air and entrained product outlet to receive a product therein to be distributed.

摘要： A seed delivery system for use in a seeding or planting machine that removes the seed from a seed meter by capturing the seed therefrom. The delivery system then moves the seed down to a lower discharge point and accelerates the seed horizontally rearward to a speed approximately equal to the forward travel speed of the seeding machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. Rolling of the seed in the trench is thus reduced. Furthermore, as the seed only has a short drop from the outlet to the bottom of the seed trench, the seed has little vertical speed to induce bounce. The delivery system uses a brush belt to capture, move and accelerate the seed. By capturing the seed and moving it from the meter to the discharge, the seed is held in place relative to other seeds and the planter row unit. As a result, the seeds are isolated from row unit dynamics thereby maintaining seed spacing.

摘要： A wing flex assembly for a frame system of an agricultural implement that includes inner and outer tubes. The outer tube, to which tools of the implement are attached, is slidingly displaceable along the inner tube as the inner tube is downwardly pivotally displaced with a downward flex of a wing frame. A first tool of a center frame can be separated from an adjacent second tool of the wing frame that is attached to the outer tube by a first distance when the outer tube is at a retracted position, and a second distance when the outer tube is slidingly displaced in response to the downward pivotal displacement of the inner tube, the first distance being about equal to the second distance. The wing flex assembly can also prevent contact between the first and second tools when the inner tube is pivotally displaced in an upward direction.

摘要： A seed placement device connected to a machine to transfer seed to a furrow includes a housing having a first opening through which seed is received and a second opening through which seed is discharged. An endless member positioned within the housing, and a drive member that controls movement of the endless member in cooperation with movement of the machine. The machine operates in a seeding direction at a travel speed, and the endless member discharges seed at a discharge speed and in a discharge direction. The discharge direction is approximately opposite to the seeding direction, and the discharge speed of the seed is at least 1.2 times the travel speed of the machine.

摘要： An example agricultural machine comprises a material distribution system that includes a material distribution line configured to convey particulate material to a component. The agricultural machine comprises a sensing system that includes a first sensor configured to generate a first sensor signal indicative of a measure of a flow of the particulate material in the material distribution line, a second sensor configured to generate a second sensor signal indicative of a measure of the flow of the particulate material in the material distribution line, and a correlation generation component configured to receive indications of the first and second sensor signals and to generate a correlation metric that represents a correlation between the first and second sensor signals. In one example, the correlation metric is applied to a sensor signal from a second material distribution line to determine a flow rate in the second material distribution line.
