Ground Wheel Driven Vibrator Or Jarring Means Patents (Class 222/619)
  • Publication number: 20100025504
    Abstract: The invention comprises a seed spreader having a cylindrical drum mounted upon a pair of wheels for traviling the drum along the wheels for distributing seed along path upon the ground. The drum rotates with the wheels as the wheels rotate along the ground as an operator pushes the wheels forward by a handle mounted to the drum. The drum is hollow and has a door which can be opened to enable seed to be deposited into the interior of the drum.

  • Patent number: 6993807
    Abstract: A dispenser for dispensing particulate cleaning material onto a floor surface includes a hopper holding the particulate material and a dispensing aperture extending across the hopper through which the material may be dispensed. A separator, which may for example be a wire, is located adjacent the dispensing aperture for separating the particulate cleaning material at the aperture. The wire helps to break up clumps of particulate cleaning material which may form. In use, a plate is vibrated to impart motion to the particulate material in the hopper. The wire can be carried by the plate or by the hopper and is preferably held under tension.

  • Patent number: 5597092
    Abstract: A collapsible drop spreader having a hopper for supporting a wheel axle bearing member, an upper U-shaped frame pivotally connected to a pair of parallel leg members supported on the hopper for use as a handle for the spreader, the hopper further having wheel track alignment guide arrows indexed thereon, a series of material exit apertures extending the length thereof, a two-part rotary agitator bar disposed above the material exit apertures of the hopper, a spring washer for biasing the separate members of the agitator bar apart to effect a sealing relationship with the wheel axle bearing supports, a light weight fiber reinforced shut-off bar disposed adjacent the material exit apertures and rotatable about splines on the wheel axle bearing members, and a flexible cable having one end connected to the rotatably journaled shut-off bar and the other end thereof connected to a control lever located on the upper frame for rotating the shut-off bar from a closed position to an open position with respect to the ma

  • Patent number: 4392595
    Abstract: Apparatus for spreading particulate material comprises a frame; a hopper supported by the frame, the hopper having a lower gravity-fed outlet aperture; a feed platform at said aperture; means for reciprocating the feed platform at said aperture relatively slowly in one direction and relatively quickly in the opposite direction; and an adjustable gate forming part of the hopper wall; all whereby the particulate material is dispensed from said hopper, beneath said gate when appropriately adjusted, by the feed platform as it reciprocates. Such apparatus may include a driven rotary feed brush for sweeping the fed particulate material in a downward direction, and constitutes a simple and inexpensive means for spreading top dressing and the like in an efficient manner.

  • Patent number: 4280663
    Abstract: A vehicle-mounted spreading apparatus includes a container for the material to be spread, at least one spreading disc rotatable about a vertical axis and a dosing device for conveying material from the container to the spreading disc as the vehicle moves along the ground. The disc and the dosing device are powered from a driving wheel which can be lowered into driving contact with the ground. The driving wheel conveys power to a mechanical power transfer assembly which drives the dosing device and which drives an adjustable speed motor system for the spreading disc.

  • Patent number: 4263858
    Abstract: A machine (FIG. 1) for dispensing seed and fertilizers, which is equipped with two hoppers one for the seed, and the other for the fertilizer. The materials flowing from outlet apertures of the hoppers while the machine is in operation are introduced into the soil in controlled amounts through proportioning means, chutes and tubes which discharge into hoes. The proportioning means have a plurality of feed wheels disposed on shafts and are driven by a ground-dependent power source.
