Agricultural vehicle with dual purpose conveyor
An agricultural vehicle includes: a chassis; at least one cleaning sieve carried by the chassis; a grain tank carried by the chassis; an unloader carried by the chassis and configured to unload crop material; and a crop material conveyor carried by the chassis and including a housing having a sieve inlet under the at least one cleaning sieve, a tank outlet coupled to the grain tank, an unloader outlet coupled to the unloader, and an endless conveyor within the housing, the crop material conveyor being configured to switch between a tank feed mode where crop material is conveyed by the endless conveyor out the tank outlet and an unload mode where crop material is conveyed by the endless conveyor out the unloader outlet.
1. An agricultural vehicle, comprising:
a chassis;
at least one cleaning sieve carried by said chassis;
a grain tank carried by said chassis;
an unloader carried by said chassis and configured to unload crop material; and
a crop material conveyor carried by said chassis and including a housing having a sieve inlet under said at least one cleaning sieve, a tank outlet coupled to said grain tank, an unloader outlet coupled to said unloader, and an endless conveyor within said housing, said crop material conveyor being configured to switch between a tank feed mode where crop material is conveyed by said endless conveyor out said tank outlet and an unload mode where crop material is conveyed by said endless conveyor out said unloader outlet.
2. The agricultural vehicle according to claim 1 , wherein said housing includes at least one tank inlet coupled to said grain tank.
3. The agricultural vehicle according to claim 2 , wherein said housing includes a tank gate associated with said at least one tank inlet and a tank gate actuator coupled to said tank gate, said agricultural vehicle further comprising a controller coupled to said tank gate actuator, said controller being configured to control an open state of said tank gate by selective activation of said tank gate actuator.
4. The agricultural vehicle according to claim 3 , wherein said controller is configured to close said tank gate when said crop material conveyor is in said tank feed mode and open said tank gate when said crop material conveyor is in said unload mode.
5. The agricultural vehicle according to claim 3 , wherein said controller is configured to close said tank gate when said crop material conveyor is in said unload mode.
6. The agricultural vehicle according to claim 3 , wherein said housing includes a tank outlet gate associated with said tank outlet and a tank outlet actuator coupled to said tank outlet gate and said controller, said controller being configured to control an open state of said tank outlet gate by selective activation of said outlet actuator.
7. The agricultural vehicle according to claim 6 , wherein said controller is configured to open said tank outlet gate when said crop material conveyor is in said tank feed mode and close said tank outlet gate when said crop material conveyor is in said unload mode.
8. The agricultural vehicle according to claim 1 , wherein said endless conveyor is configured to travel in a first direction when said crop material conveyor is in said tank feed mode and a second direction opposite to said first direction when said crop material conveyor is in said unload mode.
9. The agricultural vehicle according to claim 8 , wherein said tank outlet is upstream of said unloader outlet in the first direction.
10. The agricultural vehicle according to claim 1 , wherein said housing includes a plurality of linear travel regions.
11. The agricultural vehicle according to claim 10 , wherein said housing defines a generally quadrilateral shape.
12. A method of operating an agricultural vehicle including a chassis, at least one cleaning sieve carried by said chassis, a grain tank carried by said chassis, an unloader carried by said chassis, and a crop material conveyor configured to supply crop material to both said grain tank and said unloader with a single endless conveyor, said method comprising:
supplying crop material from said at least one cleaning sieve to a sieve inlet of said crop material conveyor;
conveying crop material out of a tank outlet to said grain tank with said endless conveyor when said crop material conveyor is in a tank feed mode; and
switching said crop material conveyor from said tank feed mode to an unload mode so that said endless conveyor conveys crop material out of an unloader outlet to said unloader.
13. The method according to claim 12 , wherein said crop material conveyor includes at least one tank inlet coupled to said grain tank and a tank gate associated with said at least one tank inlet.
14. The method according to claim 13 , wherein said switching from said tank feed mode to said unload mode comprises switching a travel direction of said endless conveyor from a first direction to a second direction which is opposite to said first direction.
15. The method according to claim 14 , wherein said switching from said tank feed mode to said unload mode further comprises opening said tank gate.
16. The method according to claim 15 , further comprising closing said tank gate and switching the travel direction of said endless conveyor from the second direction to the first direction.
17. The method according to claim 14 , wherein said tank outlet is upstream of said unloader outlet in the first direction.
18. The method according to claim 12 , said switching from said tank feed mode to said unload mode comprises closing a tank outlet gate associated with said tank outlet.
19. The method according to claim 12 , wherein said crop material conveyor includes a housing having a plurality of linear travel regions, said endless conveyor being housed within said housing.
20. The method according to claim 19 , wherein said housing defines a generally quadrilateral shape.
