초록 ▼

The selective creation of tramlines is disclosed where the metered seed normally delivered through the outlet hose (18b) of the row planter unit (20b) corresponding to the desired location of the tramline is diverted by a butterfly valve (26) to one or both of the row planter units (20a, 20c) located adjacent to and on opposite sides of the row planter unit (20b). The butterfly valve (26) includes an inlet conduit (28) which intersects with first and second outlet conduits (30, 32) and a butterfly element (34) which is pivoted by a solenoid actuator (40) against the bias of a spring (36) to selectively block one of the outlet conduits (30, 32). In the preferred form, the diverting hose (44, 54, 56) from the butterfly valve (26) may extend through the housings (24) and be in direct communication with adjacent row planter units (20a, 20c) or may be connected to Y-shaped connectors (46) having a passage (50) intersecting with the passage (48) that the metered seed for the adjacent row planter units (20a, 20c) would normally pass for mixing the metered seed. A divider (52) may be provided for dividing the metered seed diverted by the butterfly valve (26) between the two adjacent row planter units (20a, 20c). A preferred form of the butterfly valve (26) is also disclosed including first and second shoulders (90) formed in the walls (64) of the housing (58) adjacent to the inlet passageway for nesting of the free edge of the butterfly element (34). Additionally, the head portion (80) of the butterfly element (34) includes a semicylindrical portion (86) pivotal within a semicylindrical depression (72) formed in the V-shaped outlet wall (68) of the housing (58) and includes a V-shaped portion (88) extending from the semicylindrical portion (86) to the flat surfaces (84) of the dividing portion (82) of the butterfly element (34).

Valve for diverting passage of material such as seed from an inlet conduit to either first or second outlet conduits comprising, in combination: a housing defining an inlet passageway in communication with the inlet conduit and first and second outlet passageways in communication with the first and second outlet conduits with the housing including a V-shaped outlet wall including first and second outlet surfaces defining the first and second outlet passageways, with the V-shaped outlet wall including a semicylindrical depression at the junction of the first and second outlet surfaces, with the inlet and outlet passageways having the same cross sectional size, being integral and intersecting in a generally Y configuration; a butterfly element movable between a first position allowing passage from the inlet passageway to the first outlet passageway and preventing passage to the second outlet passageway and a second position allowing passage from the inlet passageway to the second outlet passageway and preventing passage to the first outlet passageway, with the butterfly element including a free edge and first and second divider surfaces, with the free edge of the butterfly element having a thickness generally equal to the thickness between the first and second divider surfaces and having a height; first and second shoulder depressions formed in the first and second outlet passageways adjacent to the inlet passageway, with the shoulder depressions each having a depth generally equal to the thickness of the free edge of the butterfly element and having a height generally equal to the height of the free edge of the butterfly element for nesting of the free edge of the butterfly element, with the free edge of the butterfly element being moveable between the first and second shoulder depressions with the free edge of the butterfly element in the first position nesting with the first shoulder depression and the first divider surface of the butterfly element being generally contiguous with the inlet passageway and with the free edge of the butterfly element in the second position nesting with the second shoulder depression and the second divider surface of the butterfly element being generally contiguous with the inlet passageway; wherein the butterfly element further comprises: a semicylindrical portion, a generally V-shaped portion having first and second flat walls, and a dividing portion terminating in the free edge and having the first and second divider surfaces, with the divider surfaces being flat and parallel, with the V-shaped portion extending outwardly from the first and second divider surfaces to the semicylindrical portion, with the first and second divider surfaces extending substantially the full length from the free edge to the V-shaped portion, with the V-shaped portion and the semicylindrical portion providing a smooth transition between the divider surfaces of the butterfly element and the first and second outlet surfaces, with the semicylindrical portion of the butterfly element having a size complimentary to and for concentric pivotal movement inside of the semicylindrical depression and for providing a linear transition between one of the flat walls of the V-shaped portion of the butterfly element and the corresponding outlet surface of the V-shaped outlet wall.
