Rotatably Mounted Cleaning Means Patents (Class 172/559)
  • Publication number: 20150021058
    Abstract: A scraper employs a support arm for mounting to a frame of an agricultural implement and a frustoconically bowl-shaped scraper member rotatably supported on the support arm in a position facing the open end of the bowl toward a ground-engaging wheel or disc. The scraper member includes a sharpened edge for improved cleaning action and uses a flanged bearing on a closed flat end of the frustoconical bowl for optimal rotational action. Different embodiment disclose unique mounting arrangements, including embodiments with a single sole support arm for ease of assembly, using bends, twists or combinations thereof to achieve suitable positioning of the scraper without additional support pieces, and including other multi-piece embodiments with multiple points of adjustability to allow optimal placement and adjustment of the scraper.

  • Publication number: 20140102736
    Abstract: A double bladed (opposite) coulter assembly is provided. A second (opposite or mirrored) coulter blade is mounted on the same coulter assembly thereby equalizing the load realized by the equipment and eliminating the draft. The second (opposite or mirrored) coulter blade reduces wear on the coulter assembly and reduces the number of coulters required by one half per equivalent tool bar thereby increasing operational efficiency of the equipment.

  • Patent number: 6874584
    Abstract: A furrow opener apparatus comprises a disc rotatably attached to the apparatus such that when the disc engages the ground, a furrow is formed adjacent to a trailing face of the disc. A scraper has a scraper blade oriented substantially parallel to the trailing face of the disc, and mounted such that the scraper blade is oriented in close proximity to or touching a lower portion of the trailing face adjacent to an outer edge of the disc. The scraper is adjustably attached to the apparatus such that the scraper blade can be moved inward along the trailing face of the disc as the disc wears while being maintained substantially parallel to the trailing face of the disc and in close proximity to or touching the trailing face of the disc. A delivery tube for agricultural material can be attached to the apparatus so that it moves in conjunction with the scraper, and the scraper can be biased against the face of the disc.

  • Patent number: 6347594
    Abstract: An opener assembly includes a single opener disk rotatably supported from a drawbar and angled approximately five degrees from the forward direction to define a shadow area behind the trailing surface of the disk. A material placement boot and delivery tube are supported adjacent the trailing surface substantially entirely within the shadow of the disk and have profiles conforming to the furrow profile. The boot and the outlet portion of the tube also lie within the periphery of the disk for protection. The tube has an upper portion with a round cross section which changes to an elliptical cross section towards the outlet to remain within the shadow while retaining high throughput capabilities. First and second wheels are supported on opposite sides of the disk to urge soil downwardly behind the outlet of the delivery tube immediately after the material is deposited.

  • Patent number: 5507351
    Abstract: This invention provides an improved apparatus for maintaining tooth rotating wheels, which are used to penetrate the soil either as a cultivating apparatus, a row cleaning apparatus, or as closing apparatus for row planters free of mulch, trash, dirt and/or rocks. By removing the debris from the space between the teeth on the wheel, the wheel can penetrate the soil to a controlled or desired depth as set by the operator. Debris between the wheels can limit the depth of penetration by the formation of a solid or semi-solid mass generally resembling of variable rim diameter. The wheels may be driven by a power mechanism or may be rotated by the penetration in the ground and the forward motion of a propulsion unit.The toothed wheel is kept clean of debris, thereby allowing accurate depth penetration as determined by conditions and requirements.

  • Patent number: 5443125
    Abstract: A grain drill row unit includes a furrow opening device that opens a furrow into which seeds are deposited as the machine advances, and a combination gauge and press wheel rides along the ground behind the furrow opening device to firm the soil around the seed and to control the depth at which the furrow opening device operates. A paddle type scraping wheel is rotatably mounted on a support above the gauge wheel axis, the scraper wheel having edges at the outer ends of the paddles, generally parallel to the axis of the scraper wheel but angled relative to the axis of the gauge wheel, the scraper wheel edges engaging material on the periphery of the gauge wheel and being rotated by contact with said material so that the scraper wheel edges scrape the periphery of the gauge wheel.

  • Patent number: 4603746
    Abstract: The present invention provides a scraper mechanism for a disk blade including a wear ring attached to the rim of a rotary scraper and releasably biased toward and held in planar contact with one side of a disk blade. The wear ring is molded from a low friction, long-wearing material, such as molded nylon. The low friction material eliminates the metal to metal contact of conventional rotary scrapers and therefore eliminates the squeal associated with rotary scrapers. Also, wear of the scraper is audibly detected when the wear ring is worn away, thereby alerting the operator that maintenance is required.

  • Patent number: 4009668
    Abstract: A method and apparatus for planting seeds. A V-shaped seed furrow having a predetermined depth is continuously formed while the soil adjacent each side of the furrow is uniformly firmed or compacted and a smooth surface formed. Seeds are continuously dispensed into the furrow. The walls of the furrow are then compacted about the seed as the furrow edges are collapsed over the seed to leave a comparatively non-compacted layer of soil above the seed. The planter is provided with a pair of furrow forming disks rotating about intersecting axes, a pair of gauge wheels rotatably supported rearwardly of the disk axes, each wheel being in close proximity to the outer surface of its respective disk, a seed dispensing means for delivering seed to the furrow, and a furrow closing device supported rearwardly of and in tracking relation to the gauge wheels.
