Flow splitter and agricultural implements having flow splitters
A flow splitter includes a body having a generally cylindrical main passage therethrough oriented along a longitudinal axis of the body. The main passage connects an inlet at the upstream end to exactly three split passages adjacent the downstream end, each split passage connected to a corresponding outlet. A first and second of the three split passages are oriented along axes that intersect one another at a first acute angle in a common plane with the longitudinal axis. A third of the three split passages intersects the common plane at a second acute angle. An agricultural implement includes a frame, a toolbar carried by the frame and supporting a plurality of row units, a hopper carried by the frame, a primary flow line connecting the hopper to a flow splitter, and three secondary flow lines connecting the flow splitter to three of the row units.
1. A flow splitter, comprising:
a body having a generally cylindrical main passage therethrough oriented along a longitudinal axis of the body, the body having an upstream end and a downstream end, wherein the upstream end and downstream end are at opposing ends of the flow splitter wherein:
the main passage connects an inlet at the upstream end to exactly three split passages at the downstream end, each split passage connected to a corresponding outlet;
a first and second of the three split passages are oriented along axes that intersect one another at a first acute angle in a common plane with the longitudinal axis; and
a third of the three split passages intersects the common plane at a second acute angle.
2. The flow splitter of claim 1 , wherein the inlet has a first inner diameter, and wherein each of the outlets has a common second inner diameter, the second inner diameter smaller than the first inner diameter.
3. The flow splitter of claim 1 , wherein the first acute angle is between 5° and 89°.
4. The flow splitter of claim 3 , wherein the first acute angle is between 20° and 70°.
5. The flow splitter claim 1 , wherein the second acute angle is between 5° and 89°.
6. The flow splitter of claim 5 , wherein the second acute angle is between 20° and 70°.
7. The flow splitter of claim 1 , wherein the body comprises a first portion and a second portion connected by at least one fastener.
8. The flow splitter of claim 7 , wherein the first portion defines the first of the three split passages, the second portion defines the second of the three split passages, and the first portion and the second portion together define the main passage and the third of the three split passages.
9. The flow splitter of claim 7 , wherein the first portion defines the third of the three split passages, the second portion defines the first and second of the three split passages, and the first portion and the second portion together define the main passage.
10. The flow splitter of claim 1 , further comprising a mount configured to secure the body to a toolbar.
11. An agricultural implement, comprising:
a frame;
a toolbar carried by the frame and supporting a plurality of row units;
a hopper carried by the frame;
a primary flow line connecting the hopper to a flow splitter, the flow splitter comprising:
a body having a generally cylindrical main passage therethrough oriented along a longitudinal axis of the body, the body having an upstream end and a downstream end, wherein:
the main passage connects an inlet at the upstream end to exactly three split passages adjacent the downstream end, each split passage connected to a corresponding outlet;
a first and second of the three split passages are oriented along axes that intersect one another at a first acute angle in a common plane with the longitudinal axis; and
a third of the three split passages intersects the common plane at a second acute angle; and
three secondary flow lines connecting the flow splitter to three row units of the plurality of row units.
12. The agricultural implement of claim 11 , wherein the flow splitter is secured to the implement such that the common plane is oriented at an angle between 0° and 70° relative to a surface of ground under the agricultural implement when the implement works the ground.
13. The agricultural implement of claim 12 , wherein the common plane is oriented at an angle between 40° and 50° relative to the surface of ground under the agricultural implement when the implement works the ground.
14. The agricultural implement of claim 11 , wherein the third outlet is oriented such that material flows vertically upward out of each of the first outlet, the second outlet, and the third outlet.
15. The agricultural implement of claim 11 , wherein the frame comprises a first section and at least one wing section hingedly coupled to the first section, wherein the flow splitter is carried by the at least one wing section.
16. The agricultural implement of claim 11 , wherein the toolbar is supported by at least one wheel.
17. The agricultural implement of claim 11 , wherein each of the row units is configured to receive solid material from the hopper and dispense the solid material to an agricultural field.
18. The agricultural implement of claim 11 , wherein each of the row units comprises a planter row unit.
19. The agricultural implement of claim 11 , wherein each of the row units comprises a fertilizer row unit.
