Vacuum system
A vacuum system that includes a planter frame. A row unit bracket couples to the planter frame. A fan couples to the planter frame and draws air through a row unit. An exhaust duct extends through the row unit bracket. The exhaust duct couples to the fan and discharges airflow from the fan towards the ground. A diffuser reduces a speed of and/or redirects the airflow as the airflow exits the exhaust duct.
1. A vacuum system, comprising:
a toolbar;
a row unit bracket configured to individually couple a respective row unit to the toolbar;
a fan coupled to the toolbar and configured to draw air through a metering system of the respective row unit;
an exhaust duct extending through the row unit bracket, wherein the exhaust duct is coupled to the fan and configured to discharge airflow from the fan toward a ground; and
a diffuser configured to reduce a speed of the airflow, to redirect the airflow, or a combination thereof, as the airflow exits the exhaust duct.
2. The system of claim 1 , wherein the diffuser comprises a first section and a second section, wherein the second section is positioned downstream from an outlet of the exhaust duct.
3. The system of claim 2 , wherein the second section extends over the outlet of the exhaust duct.
4. The system of claim 2 , wherein the second section covers a portion of the outlet of the exhaust duct.
5. The system of claim 2 , wherein the second section is angled relative to the ground.
6. The system of claim 2 , wherein the second section is perforated.
7. The system of claim 1 , wherein the diffuser defines a conical surface.
8. The system of claim 7 , wherein a portion of the conical surface rests within the exhaust duct.
9. The system of claim 1 , wherein the diffuser comprises a flexible material.
10. The system of claim 9 , wherein the exhaust duct defines a slot configured to receive a perforated plate.
11. A vacuum system, comprising:
an exhaust duct configured to extend through a row unit bracket, wherein the exhaust duct is configured to couple to a fan configured to draw air through a metering system of a respective row unit, the exhaust duct is configured to discharge airflow from the fan toward a ground, and the row unit bracket is configured to individually couple the respective row unit to a toolbar; and
a diffuser configured to reduce a speed of the airflow, to redirect the airflow, or a combination thereof, as the airflow exits the exhaust duct.
12. The system of claim 11 , wherein the diffuser comprises a first section and a second section, wherein the second section is positioned downstream from an outlet of the exhaust duct.
13. The system of claim 12 , wherein the second section is angled relative to the ground.
14. The system of claim 12 , wherein the second section is perforated.
15. The system of claim 11 , wherein the diffuser defines a conical surface.
16. The system of a claim 11 , wherein the diffuser comprises a flexible material.
17. A vacuum system, comprising:
a row unit bracket configured to individually couple a respective row unit to a toolbar;
an exhaust duct extending through the row unit bracket, wherein the exhaust duct is configured to couple to a fan configured to draw air through a metering system of the respective row unit, and the exhaust duct is configured to discharge airflow from the fan toward a ground; and
a diffuser configured to reduce a speed of the airflow, to redirect the airflow, or a combination thereof, as the airflow exits the exhaust duct.
18. The system of claim 17 , wherein the diffuser comprises a plate downstream from an outlet of the exhaust duct.
19. The system of claim 17 , wherein the diffuser comprises a flexible material.
20. The system of claim 17 , wherein the diffuser comprises a surface that forms an angle relative to the ground.
