Abstract
A seeding device to dispense seed suspended in a gel or other carrier medium in either a continuous stream or discrete pulses. A coulter opens a furrow of earth to the proper depth and seed carried in a gel or other suspension medium is delivered in a pulsed or continuous stream into the furrow which is then covered with earth by a trailing coverer. An auger delivers the seed in suspension and the speed of the auger is controlled to vary the volume of seed and gel or other suspension medium delivered. Circumferentially spaced cam lobes on a drive wheel control the frequency and therefore the row spacing of the seed suspension medium distributed in the pulse delivery mode.
Claims9
A seeding device for delivery of seed carried in a fluid delivery substance comprising,
- a housing,
- storage means on said housing for retaining a supply of seed in said fluid delivery substance,
- metering means operatively connected to said storage means to transfer said seed in said fluid delivery substance to a delivery outlet,
- means to selectively vary said metering means to control the quantity of said seed in said fluid delivery substance dispensed from said delivery outlet,
- means to eject said fluid delivery substance in spaced pulsed batches, said means to eject said fluid delivery substance in spaced pulsed batches includes a flexible bulbous storage member in fluid communication with said delivery outlet and wherein said fluid delivery substance is retained within said bulbous storage member to be ejected at predetermined spaced intervals, and
- drive means associated with said housing to move said housing and said metering means along an area to be seeded, said drive means including a wheel support for rolling contact with the ground and means operatively interconnected said wheel support to said bulbous storage member to eject said fluid delivery substance at said predetermined spaced intervals, said means operatively interconnecting said wheel support to said bulbous storage member includes a cam means coupled to said wheel support for rotation therewith, a rocker arm pivotally secured to said housing, a cam follower carried by said rocker arm, means for selectively positioning said cam follower with respect to said cam means to enable contact at selectively variable intervals between said cam means and said cam follower upon rotation of said wheel support, the contact effecting an intermittent pivoting movement of said rocker arm from a first position to a second position, said rocker arm including means for contacting said bulbous storage member and being displaced from said bulbous storage member when said rocker arm is in said first position and pivotable to a second position in operative position to effect discharge of said fluid delivery substance from said bulbous storage member when said rocker arm is in said second position.
