Removal of the rotary metering member is therefore simply achieved by releasing the closure member pivotting it away from the housing and withdrawing the metering member and shaft laterally through the now open ends of the slots.

Abstract: A hygroscopic-fertilizer-pellet applicator of the type having a fan blowing air through small tubes to propel the pellets to tube outlets for underground placement. The tendency of the hygroscopic fertilizer to absorb moisture, and to clog the small tubes, is relieved herein by heating the air which then dries the fertilizer. The source of heat is to have the fan pulling ambient air through a heat exchange, which latter is heated by hydraulic fluid flowing through it from a hydraulic motor operating the fan. The compression of the air by the fan further heats the air.

The granular material is fed into the mixer unit at the approximate radius of curvature center for the curved passageway. The centrifugal movement of the air produces a vacuum at the radius of curvature center allowing for gentle acceleration of the granular material.

A groove formed on the distributor surface extends over the suction orifice, the axis of the groove being perpendicular to the path of travel of the suction orifice, with a deflector the limit of the action range of which is clear from the path of travel of the axis of the suction orifices by about the radius of a seed.

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.

Abstract: In a seed meter in which a seed disk having a circular outer edge is rotatably mounted on a hub within a generally cylindrical housing, an elongated cleanout and seed sealing member mounted within the housing adjacent a substantial portion of the circumference of the outer edge of the seed disk forms a generally uniform space or gap with the outer edge of the seed disk which is large enough to pass most seed chips, broken seeds, dirt and other debris therethrough but small enough to prevent seeds contained within the housing and adjacent the seed disk from escaping therethrough. The cleanout and seed sealing member has a sloped surface adjacent the outer edge of the seed disk which provides the space or gap with a size that increases with increasing distance from the axis of rotation of the seed disk to facilitate the escape of debris.

Abstract: A section of tube with a series of inwardly directed projections is placed in the main conduit of a pneumatic applicator, upstream of the primary distribution head. The inner projections in the tube serve to center the direction of the blown granular material into the primary distributor head.

Abstract: A clearing blade, as an attachment for a garden tractor or the like, is constructed as a double-walled construction thereby forming a box-like spreading funnel (5) between the wall members so that simultaneously with or after clearing snow, salt or other granular material may be spread by the same implement used for the clearing. Due to the rigid box-structure of the blade a sufficient strength is obtained even by materials of lesser strength than expensive, fracture resistant steels. Hence, such materials of lesser strength, e.g., synthetic materials, may be used for manufacturing the present blade by an injection molding or die-casting method.

Abstract: A funnel-shaped device is provided with one or two segments serving as brackets to enlarge the bottom opening of the funnel which, when closed, is smaller than the smallest piece of grain to be deposited; a centrally disposed air tube blows air axially toward the bottom opening to cause a single piece of grain to be aerodynamically held on the opening while the remainder of the grains hover at a higher level. A slide element such as a fork or the like can be removably disposed at an intermediate level, possibly to serve for opening a single-bracket element. This permits a lower hovering level and a correspondingly increasing cycle time and depositing rate.

The excess billets fall from the conveyor slat 102 and onto the return sheet 226.

Abstract: The present invention is an improved seed sower unit and an improved seed supply hopper for the head. Opposed vacuum disc-type sower units are mounted in a frame. A seed hopper is mounted on a separate subframe. The hopper subframe has mounting notches which rest on stub pins projecting from the main frame. A latch mechanism holds the seed hopper subframe in place during operation. By opening the latch, the subframe with the seed hopper can be lifted vertically from between the sower discs to permit ready access for cleaning or repair. The seed hopper portion has a sloping bottom member adapted to fit between the sower discs to form a seed trough. This sloping member has a gate so that seed can be easily drained from the system into a container without loss. An optional second gate enables the seed hopper to be isolated from the seed trough. By making the seed hopper vertically removable, the sower units may be located in close proximity to each other, thus enabling similarly close crop row spacing.

Abstract: A planting machine wherein its planter wheel and a packer wheel trailing the same respectively have peripheral velocities greater and less than the speed of advance of the machine. Shoes on the former open the ground and deposit a seed therein on relative rearward movement, with feet on the packer wheel covering deposited seeds on forward movement thereof relative to the ground. The drives for the planter and packer wheels are interconnected to minimize the overall power requirement. Seeds are dispensed from a hopper to a position adjacent the axle of the planter wheel and spirally nested delivery tubes gravitationally deliver the dispensed seeds to the planter shoes in an arrangement such that a seed is delivered to a shoe only after a predetermined advance of the seed has occurred subsequent to its having been dispensed.

Abstract: A planter is moved through a field to place two rows of four plants on the top of a planting bed between adjacent irrigation furrows. Plants ready for transplant are disposed in trays within polymerized cast soil plugs. Each plug is disposed within the tray in a hole. Each tray has rows and columns of plant receiving holes extending through each tray. The planter carrying the plugs moves in increments and sets the planter mechanism in a stationary position over the top of the planting bed prior to plug planting. The tray carrying the transplants is registered horizontally and vertically to a plug receiving cylinder by respective cams and a supporting chain. Upon registry, polymer plugs containing sprouted plants therein are ejected, typically eight at a time, by ejecting fingers penetrating the plant receiving holes. Ejection occurs with the plants horizontally disposed into receiving concavities defined within a rotating cylinder.

Abstract: An apparatus for continuously metering seeds onto a seedbed and simultaneously pressing the seeds into the soil. The seed planting apparatus includes a drum adapted to be moved in rolling contact across the seedbed, and which transports seeds on its peripheral wall from a hopper to the seedbed.

A cam interrupts the vacuum by compressing the hoses when the seed-bearing apertures contact the seedbed, thereby releasing the seeds and pressing them into the soil. The seeds are preferably placed on the seedbed in a uniformly spaced array predetermined by the uniform alignment and spacing of the apertures on the wall of the drum.
