Abstract

A flow splitter for distributing agricultural products may include a splitter body defining an inlet port and a plurality of outlet ports. The flow splitter may also include at least two baffle plates positioned within the splitter body so as to divide an internal flow chamber of the splitter body into a plurality of downstream flow channels. Additionally, the flow splitter may include a divider plate positioned within the splitter body upstream of the baffle plates such that the divider plate is spaced apart from upstream edges of the baffle plates in a direction of the inlet port of the splitter body. The divider plate may be configured to initially divide an input flow of agricultural product received at the input port into two separate product flows for subsequently delivery into the plurality of downstream flow channels.

First claim

What is claimed is:

1. An agricultural product distribution system, comprising:
an input tube configured to receive an input flow of agricultural product;
a plurality of output hoses provided downstream of the input tube; and
a flow splitter provided between the input tube and the plurality of output hoses for transporting the input flow of agricultural product from the input tube to the plurality of output hoses, the flow splitter comprising:
a splitter body extending lengthwise between an upstream end and an opposed downstream end, the splitter body defining an inlet port at or adjacent to its upstream end that is in flow communication with the input tube and a plurality of outlet ports at or adjacent to its downstream end, each of the plurality of outlet ports being in flow communication with a respective output hose of the plurality of output hoses, the splitter body further defining an internal flow chamber extending between the inlet port and the plurality of outlet ports;
at least two baffle plates positioned within the splitter body so as to divide the internal flow chamber into a plurality of downstream flow channels, each downstream flow channel extending from an upstream edge of one or more of the at least two baffle plates to a corresponding outlet port of the plurality of outlet ports; and
a divider plate positioned within the splitter body upstream of the at least two baffle plates such that the divider plate is spaced apart from the upstream edges of the at least two baffle plates in a direction of the inlet port of the splitter body, the divider plate being configured to initially divide the input flow of agricultural product received at the input port into two separate, substantially equal product flows upstream of the at least two baffle plates for subsequent delivery into the plurality of downstream flow channels.

2. The agricultural product distribution system of claim 1 , wherein the splitter body extends in a cross-wise direction between a first sidewall and a second sidewall, the divider plate being spaced apart equally from the first sidewall and the second sidewall in the cross-wise direction.

3. The agricultural product distribution system of claim 1 , wherein the divider plate extends lengthwise between an upstream edge and a downstream edge, the upstream edge being positioned at or adjacent to the upstream end of the splitter body.

4. The agricultural product distribution system of claim 1 , wherein the splitter body defines a central axis extending between its upstream and downstream ends, the divider plate extending lengthwise along the central axis.

5. The agricultural product distribution system of claim 4 , wherein at least one of the inlet port or a central outlet port of the plurality of outlet ports is aligned with the central axis.

6. The agricultural product distribution system of claim 4 , wherein the at least two baffle plates are angled relative to the central axis.

7. The agricultural product distribution system of claim 4 , wherein the at least two baffle plates are offset from the central axis in a cross-wise direction of the splitter body, the cross-wise direction extending perpendicular to the central axis.

8. The agricultural product distribution system of claim 1 , wherein the divider plate defines a length along a lengthwise direction of the splitter body, wherein the divider plate is spaced apart from the upstream edges of the at least two baffle plates by a lengthwise distance in the lengthwise direction that is greater than about 50% of the length of the divider plate.

9. The agricultural product distribution system of claim 8 , wherein the lengthwise distance ranges from about 80% to about 100% of the length of the divider plate.

10. The agricultural product distribution system of claim 1 , wherein the input tube comprises a dimple tube.

11. The agricultural product distribution system of claim 1 , wherein the at least two baffle plates include a first baffle plate and a second baffle plate spaced apart from the first baffle plate in a cross-wise direction of the splitter body such that a first downstream flow channel of the plurality of flow channels is defined directly between the first and second baffle plates, both of the first and second baffle plates being spaced apart from the first and second sidewalls in the cross-wise direction of the splitter body, the first downstream flow channel extending from an upstream edge of the first and second baffle plates to a corresponding outlet port of the plurality of outlet ports.

12. The agricultural product distribution system of claim 11 , wherein the divider plate is substantially aligned with the first downstream flow channel along the lengthwise direction of the splitter body.

13. A flow splitter for distributing agricultural products, the flow splitter comprising:
a splitter body extending lengthwise between an upstream end and an opposed downstream end, the splitter body defining an inlet port at or adjacent to its upstream end and a plurality of outlet ports at or adjacent to its downstream end, the splitter body further defining an internal flow chamber extending between the inlet port and the plurality of outlet ports;
at least two baffle plates positioned within the splitter body so as to divide the internal flow chamber into a plurality of downstream flow channels, each downstream flow channel extending from an upstream edge of one or more of the at least two baffle plates to a corresponding outlet port of the plurality of outlet ports; and
a divider plate positioned within the splitter body upstream of the at least two baffle plates such that the divider plate is spaced apart from the upstream edges of the at least two baffle plates in a direction of the inlet port of the splitter body, the divider plate being configured to initially divide a input flow of agricultural product received at the input port into two separate, substantially equal product flows upstream of the at least two baffle plates for subsequent delivery into the plurality of downstream flow channels.

14. The flow splitter claim 13 , wherein the splitter body extends in a cross-wise direction between a first sidewall and a second sidewall, the divider plate being spaced apart equally from the first sidewall and the second sidewall in the cross-wise direction.

15. The flow splitter claim 13 , wherein the divider plate extends lengthwise between an upstream edge and a downstream edge, the upstream edge being positioned at or adjacent to the upstream end of the splitter body.

16. The flow splitter claim 13 , wherein the splitter body defines a central axis extending between its upstream and downstream ends, the divider plate extending lengthwise along the central axis.

17. The flow splitter claim 16 , wherein at least one of the inlet port or a central outlet port of the plurality of outlet ports is aligned with the central axis.

18. The flow splitter claim 16 , wherein the at least two baffle plates are angled relative to the central axis.

19. The flow splitter claim 16 , wherein the at least two baffle plates are offset from the central axis in a cross-wise direction of the splitter body, the cross-wise direction extending perpendicular to the central axis.
