- a plurality of cleanout doors 140 are preferably pivotally mounted to the entrainer 100 about a common axis generally indicated by reference character A.
- Unlatching a pair of latches 142 associated with each cleanout door 140 permits the operator to remove unused seed from the entrainer 100.
- An air line (not shown) directs air from the blower 820 into a manifold 130.
- the manifold 130 extends longitudinally through the entrainer 100, supplying air flow to each entrainer module 200.
- the bulk hopper 810 is mounted to an upper end of the entrainer 100 such that seeds flow by gravity from the bulk hopper into the entrainer 100.
- the entrainer module 200 is illustrated in detail; the entrainer modules 200 are preferably interchangeable.
- Seed flows in dense phase from the bulk hopper 810 into a tapered entry region indicated generally by reference numeral 210. Seed flows in dense phase from the tapered entry region into an inlet 220 bounded on transverse sides by a wall 280 of the entrainer module 200 and a wall 280 of a neighboring entrainer module 220 (see, e.g., the inlet 220-5 illustrated in FIG. 6, bounded by the walls 280-5 and 280-4).
- each entrainer module 200 preferably includes corresponding extrusions 284 and slots 282 by which neighboring entrainer modules are preferably mated.
- a bulk seed delivery system 800 is illustrated in FIG. 8. It should be appreciated that in some embodiments the components of the system 800 are those described elsewhere herein and having like reference numerals.
- the bulk hopper 810 is preferably in seed communication, preferably dense phase seed communication, with the module entry regions 210-1 through 210- 18 (it should be appreciated that although the embodiment described herein is an 18-row embodiment, other maximum numbers of rows per entrainer are contemplated).
- Each module entry region 210 is in seed communication, preferably dense phase seed communication, with the associated entrainer module 200.
- the blower 820 is in fluid communication with the manifold 130.
- the manifold 130 is preferably in fluid communication with each of the modules 200.
- each module 200 is preferably in fluid and seed communication with an associated row unit auxiliary hopper 18 via an individual seed supply line 880.
- An air-seed mixture i.e., air- entrained seed travels from each module 200 to the associated auxiliary hopper 18 through the associated seed supply line 880.
- each module 200 of the entrainer 100 is preferably configured to partially receive a blocking wedge 300 in an upper portion of the inlet 220.
- a blocking wedge e.g., blocking wedge 300-5
- seed is prevented from flowing from the bulk hopper 810 into the affected module 200 (e.g., module 200-5).
- the blocking wedges 300 effectively reduce the entrainer 100 from its maximum 18 -row
- Multiple row configurations may be achieved using the same entrainer by selectively blocking varying numbers of modules 200 using blocking wedges 300.
- each blocking wedge 300 preferably includes extruding ridges 322-B, 322-F formed in opposing sides of the block.
- the ridges 322 are preferably configured to fit within corresponding notches 222-B, 222-F formed in the back and front, respectively, of the inlet 220.
- Each notch is preferably configured to retain a vertical position of the blocking wedge, e.g., by contacting upper and lower surfaces of the ridge 322 in the illustrated embodiment.
- the notches 222-B, 222-F are preferably substantially symmetrical about a vertical plane, and the ridges 322 are preferably substantially symmetrical about the same plane when the blocking wedge 300 is inserted in the inlet 220, such that the same blocking wedge 300 may be inserted either in a left-facing or right-facing orientation into the inlet 220.
- each blocking wedge 300 preferably includes an angled surface 350, preferably oriented at approximately 45 degrees from vertical.
- Blocking wedges inserted in outboard entrainer modules are preferably oriented in an "inboard-facing" orientation such that the angled surface 350 faces inboard, guiding dense phase seed toward the transverse center of the entrainer 100 as the seed flows from the bulk hopper 810 into the entrainer.
- outboard entrainer modules e.g., modules 300-3 and 300-18
- the blocking wedges 300 may be used interchangeably to block left-side or right-side outboard entrainer modules with the desired inboard-facing orientation.
- each blocking wedge 300 prevents seed from entering the associated entrainer module such that seed introduced to the bulk hopper 810 can be planted in its entirety from each of the unblocked entrainer modules without leaving unplanted seed in the blocked entrainer modules.
- a process 1000 for selecting an entrainer row configuration is illustrated in FIG. 10.
- the operator connects a seed supply line 880 to the outlet 290 of a subset of the modules 200.
- the subset comprises eight of the modules 200 such that eight of the module outlets 290 are placed in seed and fluid communication with individual seed supply lines 880.
- the subset of module outlets is preferably substantially evenly distributed among the outlets 290; for example, in the illustrated embodiment having eighteen entrainer modules 200-1 through 200-18, a subset of eight selected module outlets preferably comprises the module outlets 290-2, 290-4, 290-6, 290-8, 290-11, 290-13, 290-15, 290-17.
- the operator preferably closes the remainder of the module outlets 290, i.e., the outlets not selected at step 1005; in some embodiments, a cap (not shown) is used to seal the remainder of the module outlets.
- the operator preferably inserts a blocking wedge 300 in the inlet 220 of each of the remainder of the modules 200, i.e., the modules not in the subset selected at step 1005.
- the operator preferably orients the blocking wedges 300 to guide seed flowing from the bulk hopper 810 toward the longitudinal center of the entrainer 100; e.g., by orienting the angled surfaces 350 in an inboard-facing manner as best illustrated in FIG. 6. It should be appreciated that the steps 1010 and 1015 are preferably performed substantially simultaneously, e.g. by orienting the blocking wedge 300 as desired while inserting it into the inlet 220.
- the operator preferably mounts the bulk hopper 810 to the entrainer 100.
- the operator preferably connects each of the seed supply lines 880 to a row unit auxiliary hopper 18 such that each of the subset of modules 200 selected at step 1005 is in fluid and seed
- the operator preferably adds seed to the bulk hopper 810.
- seed is guided over a plurality of blocking wedges (e.g., blocking wedge 300-5 in FIG. 6) into the inlet 220 of an entrainer module 200 inboard of and adjacent to each blocking wedge 300 (e.g., module 200-6 of FIG. 6).
- the operator preferably supplies air pressure to the manifold 130 (e.g., by supplying power to the blower 820) such that seed is entrained and supplied to each of the row unit auxiliary hoppers 18.
- steps of process 1000 may be carried out at different stages by different operators; for example, the steps 1010, 1015, 1020 may be performed in an assembly phase by a manufacturer while the remaining steps may be performed in a setup phase by a retailer or end user.
- the planter 10 is provided with a plurality (preferably two) bulk hoppers 810 and entrainers 100.
- entrainer 100 embodiments described herein comprise individual separable entrainer modules, other entrainer embodiments may comprise multiple entrainer modules having discrete outlets but formed as a single unitary part.
