  • Publication number: 20100192821
    Abstract: A seed delivery apparatus has a moving member that captures and entraps the seed from the seed meter and physically moves the seed from the meter to the lower outlet opening. In so doing, the seed engages and travels along an interior surface of the seed delivery apparatus. A seed sensor is mounted on the housing wall such that the seed passes directly in front of the sensor. The sensor has both the light emitting devices and the photo-sensitive elements on the same wall of the delivery apparatus, or on two opposed walls. The moving member prevents ambient light, dust and dirt from entering the housing and impacting the sensor output signal.

  • Publication number: 20100192819
    Abstract: 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.

  • Patent number: 7717048
    Abstract: A seeding machine having at least one tool bar, a plurality of row units and a processing circuit. Each of the plurality of row units are connected to the toolbar. Each of the row units have a seed metering device, a seed placement device and a seed sensor. The seed metering device includes a seed disk providing a metering action to a plurality of seeds. The seed placement device receives the seeds from the seed metering device. The seed sensor is positioned to detect the passage of seeds through either the metering device or the seed placement device. The seed sensor producing a signal indicative of the passage of the seeds. The processing circuit is receptive of the signal from each of the seed sensors of each of the plurality of row units. The processing circuit determines a seed placement parameter dependent upon the signal, the processing circuit alters the metering action of the seeds dependent on the seed placement parameter.

  • Publication number: 20100116185
    Abstract: A seed meter for use in an agricultural seeding machine includes a housing having an inner chamber and one or more deflectors within the inner chamber, and a seed disc rotatably carried by the housing. The seed disc includes at least a portion thereof formed from a flexible material which is deflectable by the one or more deflectors during rotation within the housing.

  • Patent number: 6848377
    Abstract: An assembly for opening and closing a furrow in soil includes a furrow opener with a pair of discs positioned at an angle relative to each other. The discs each have an inner side facing toward each other and an outer side facing away from each other. Each disc also has a leading edge and a trailing edge relative to a travel direction. A furrow closer includes a pair of wheels, each having an inner side facing toward each other and positioned adjacent to a corresponding disc outer side. Each wheel also has a leading edge positioned between a corresponding disc leading edge and disc trailing edge, and a trailing edge positioned rearward of a corresponding disc trailing edge relative to the travel direction.

  • Patent number: 5394946
    Abstract: A row cleaning attachment for seeding equipment comprising a coulter mounted between and behind two press wheels having a uniform circumference. The press wheels are independently spring biased downwardly into contact with the ground for holding and pulling the crop residue away from the planting line of the planting unit. The coulter has a larger diameter than the press wheels and is located so that the cutting edge of the coulter cuts the residue material as it is being tensioned between the press wheels.

  • Patent number: 5161473
    Abstract: A seed distribution system includes an upright main hopper for containing a mass of seeds. The input end of a seed tube projects into the lower portion of the hopper near the bottom of the seed mass. The input end of the seed tube is located within the output end of an air supply tube and terminates inwardly of the supply tube. The seeds in the main hopper are pneumatically captured by creating a generally dome-shaped area in the seeds adjacent the input end and sweeping seeds from the area into the input end. The captured seeds are propelled through the seed tube to a secondary hopper adjacent a seed metering device. To provide automatic level control, the delivery end of the seed tube is supported within the secondary hopper so that, as the seed level rises in the hopper, air flow and thus seed delivery rate will decrease.
