Abstract
An unloading system for an agricultural vehicle includes: a grain tank; at least one cross auger placed within the grain tank; a discharge tube having an inlet in communication with the grain tank and at least one discharge auger placed therein; and a drive system configured to drive the at least one cross auger and the at least one discharge auger. The drive system includes: a main driver; a discharge coupling continuously coupled to the main driver and the at least one discharge auger; and a variable speed coupling continuously coupled to the main driver and coupled to the at least one cross auger.
Claims20
An unloading system for an agricultural vehicle, comprising:
- a grain tank;
- at least one cross auger placed within said grain tank;
- a discharge tube having an inlet in communication with said grain tank and at least one discharge auger placed therein;
- and
- a drive system configured to drive said at least one cross auger and said at least one discharge auger, said drive system including:
- a main driver;
- a discharge coupling continuously coupled to said main driver and said at least one discharge auger;
- and
- a variable speed coupling continuously coupled to said main driver and coupled to said at least one cross auger.
An agricultural vehicle, comprising:
- a chassis;
- a power plant carried by said chassis;
- and
- an unloading system carried by said chassis and including:
- a grain tank carried by said chassis;
- at least one cross auger placed within said grain tank;
- a discharge tube having an inlet in communication with said grain tank and at least one discharge auger placed therein;
- and
- a drive system configured to drive said at least one cross auger and said at least one discharge auger, said drive system including:
- a main driver coupled to said power plant;
- a discharge coupling continuously coupled to said main driver and said at least one discharge auger;
- and
- a variable speed coupling continuously coupled to said main driver and coupled to said at least one cross auger.
A method of controlling crop material discharge in an agricultural vehicle including a grain tank, at least one cross auger placed within said grain tank, a discharge tube having an inlet in communication with said grain tank and at least one discharge auger placed therein, and a drive system including a main driver, said method comprising:
- rotating said at least one discharge auger via a discharge coupling continuously coupled to said main driver and said at least one discharge auger;
- rotating said at least one cross auger via a variable speed coupling continuously coupled to said main driver and coupled to said at least one cross auger;
- and
- adjusting a drive ratio of said variable speed coupling to change a rotation speed of said at least one cross auger.
