Definitions

  • ABSTRACT Apparatus for separating and/or counting individual ones of a plurality of substantially similarly shaped particles, elements, grains, or the like, such as grains of seed, pills, etc., and including a hollow rotating drum, constructed to have plural, inwardly tapering indentations, terminating in a bore open to the interior of the drum and having at the bottom of the indentation dimensions smaller than the particles so that the particles cannot traverse the bore, the indentations being wider than the particles at the surface of the drum, the indentation dimensioned to hold at least one particle each.
  • a nozzle directs an air jet towards the drum at direction and position so that the air strikes along the leading wall portion of the closest indentation as the drum rotates. Particles are fed towards the drum, so that at least one particle is in each indentation as it passes the jet.
  • the present invention relates to apparatus for separating and/or counting individual elements taken or to be taken from a quantity of approximately similarly shaped elements such as seed, pills, plastic particles or the like. More particularly, the invention relates to improvements in counting or separating apparatus which includes a housing, a bucket wheel or drum, journalled in the housing, a storage bin or the like and a feeder arrangement extending from bin to drum.
  • Sowing or seeding machines with single seed dispensing mechanism use a bucket wheel wherein the individual compartments are usually dimensioned so as to receive, possibly, only one seed grain. That seed is ejected upon continued turning of the wheel, and at a different location, if possible, into a prepared furrow.
  • These machines pose the problem that each compartment should contain only one grain of seed, not two, and it should also not remain empty, otherwise growth retardation and/or a gap in the row of expected plants is inevitable.
  • indentations in a drum which taper in inward direction, e.g., by having conical configuration. These indentations may be located either along periphery of the drum or on axial end faces thereof.
  • the apeces are not fully developed, i.e., the cones are actually trunkated.
  • the smallest diameter in each indentation is smaller than the diameter of the smallest particle or element to be separated.
  • the housing in which this drum is journalled is equipped with a blower having a nozzle that directs a jet towards the drum not quite tangentially to the wall of the indentation underneath, but at a slight angle particularly in relation to one portion of the inner wall of a tapering indentation.
  • the apex angle of each cone should be from within the range from 40 to preferably about 45 to 60.
  • the drum itself is preferably exchangeably and displaceably disposed in housing journals.
  • the conical indentations or bores are somewhat overdimensioned to receive at least one particle, element, grain etc. with certainty, but possibly more than one.
  • the jet will cause the one lowest particle in each bore to be sucked against the bottom wall portion of the bore, while the superfluous particles are flushed out.
  • FIG. 1 is a side view of a seeder machine in which the invention can be practiced
  • FIG. 2 illustrates side view, partially as section view, of an arrangement in accordance with the preferred embodiment of the invention, including incorporating feature for employment in a seeder machine;
  • FIG. 3 shows section view along line IIIIII of FIG. 2;
  • FIGS. 4 and 4a are respectively section view and top view into a bore that receives an element to be dispensed, counted, etc.
  • FIG. 1 illustrates a tubular carrier 1 that extends from a tractor.
  • a clamp 2 is secured to carrier 1 as holder for a parallel construction and guide frame 3.
  • the holder journals the two parallel arms 3a and 3b, and the fourth side is established by the frame 4 of the seeder machine, holding a seeder blade 5, a seeding apparatus proper 6 with feeder 7, and an air intake (outlet of a blower) 8.
  • a stripper 9 and a roller 10 for closing the furrow are likewise connected to the frame part 4a.
  • Roller 10 is pivotable linked to the frame as is known per se. Adjusting means 11 permit angular adjustment and elevation adjustment of the roller.
  • a bucket wheel or drum 12 is disposed, i.e., journalled in a housing 17 of the seeder apparatus 6.
  • the drum 12 is driven in a manner known per se.
  • a plurality of radially inwardly directed bores or indentations 13 of conical configuration traverse the drum which is hollow in the interior. Actually, the conical indentations each merge with cylindrical bores 13a.
  • FIGS. 4a and 4b respectively show section and top view (radially inward) of such a bore.
  • the housing 17 of the feeder is constructed to accommodate a feeder chamber whose bottom 14a is inclined to the horizontal, so that grain (seeds) can slide down, and towards the drum 12. Grain enters chamber 14 through a chute or other suitable feeder input 7.
  • the opening of the storage and feeder facility 14 towards the drum is selected to span about three indentations or bores 13, so that each will be filled with certainty with one or even several grains of seed.
  • the volume of each conical bore is selected so that each can receive more than one grain.
  • a portion of the upper wall of chamber 14 is provided as air intake 8 terminating in a nozzle of meniscus-like cross section (see FIG. 3). That nozzle is disposed in the immediate vicinity of the periphery of drum 12.
  • the meniscus-shaped nozzle 15 has configuration that matches the contour of the upper (outer) edge or rim of each bore 13 (see FIG. 3), for a drum with a single peripheral row of bores.
  • the nozzle has configuration so that the radius of curvature of the convex arc of the nozzle is approximately similar to the radius of curvature of the upper (outer) rim of the bore 13.
  • the wall of housing 17 encloses most of the drum 12 to retain the particles in the bores.
  • the bottom has a seed ejection opening 16. It may be of advantage to provide a reciprocating ejector in the interior of the drum.
  • the ejection may be positioned excentrically in the drum but rotating therewith.
  • the spokes may enter the bores 13a and 13 when in lower position to push the grains out of the bores. Care must be taken that a grain is not squeezed against the bottom wall of housing 17 before the compartment reaches opening 16 pursuant to the rotation.
  • each bore 13a is filled with at least one, possibly more than one grain of seed.
  • the jet hits the leading wall of the particular conical bore 13 underneath as passing; the jet continues around the grain or grains through opening 13a towards the interior of the drum.
  • each bore actually accelerates the air jet. This acceleration is significant, even if a bore is empty. It is even more so when grains are in the respective bore, so that most of the air is actually deflected and returns along the trailing wall portion of bore 13, into the interior of feeder chamber 14.
  • the flushing or blowing of superfluous grains from each bore has the advantage that they will not be damaged.
  • the pressure used for blowing air into each bore passing nozzle 15 is selected in accordance with the approximately similar weight for the grain elements. Also, the size of the bore (which is determined by the size of the grain) and the estimated flow throttling resistance for air in a partially filled bore are parameters for the jet pressure.
  • the seeder machine is used, for example, for sowing corn, it is not necessary to gauge or otherwise sort or classify the corn kernels, and still it is ensured that there will be one kernel (nor more, not less) in a bore 13.
  • the basic components can be used in substantially similar arrangements and even in similar configuration for counting or separating other types of particles. Possibly needed modifications may include a closing means for the ejection opening 16. After having a particular number of particles deposited into the compartments-indentations (which is determined by a particular angular displacement path or a number of revolutions of the drum), opening 16 is temporarily closed until the container underneath has been replaced by an empty one.
  • a compartmentized drum bucket wheel
  • Apparatus for separating and counting individual ones of a plurality of substantially similar shaped particles, elements, grains, or the like, such as grains of seed, pills, etc. and including a rotating drum, feeder means for the particles and a housing for the drum, the
  • the drum being hollow and constructed to have plural inwardly tapering indentations, terminating in a bore open to the interior of the drum and having at the bottom of the indentation dimensions smaller than the particles so that the particles cannot traverse the bore, the indentations being wider than the particles at the surface of the drum, the
  • indentation dimensioned to hold at least one particle each; means including a nozzle for directing an air jet towards the drum at direction and position so that the air jet is directed towards and into an indentation striking along the leading wall portion thereof as the drum rotates; and
  • the feeder means constructed to feed particles towards the drum, so that at least one particle is in each indentation as it passes the jet.
  • the drum disposed in a cylindrical housing covering the drum for most of its circumference, the feeder means opening the housing along the remaining part of the circumference, the nozzle arranged at the one end of the opening where, in direction of rotation, the drum surface enters cover by the housing.
