Abstract
An agricultural planter including a frame member, a conveyance system, a seeding system and an air pressure differential system. The conveyance system is coupled to the frame member and the conveyance system allows for the moving of the planter at a ground speed. The seeding system is coupled to the frame member. The air pressure differential system is operatively coupled to the seeding system. The air pressure differential system includes an air pressure differential producing apparatus for producing an air pressure difference and a controller. The controller is in controlling communication with the air pressure differential producing apparatus. The controller is configured to select the air pressure difference dependent upon the ground speed of the planter.
Claims20
An agricultural planter, comprising:
- a frame member;
- a conveyance system coupled to said frame member, said conveyance system allowing for the movement of the planter at a ground speed;
- a seeding system coupled to said frame member;
- and
- an air pressure differential system operatively coupled to said seeding system, said air pressure differential system including:
- an air pressure differential producing apparatus for producing an air pressure difference;
- and
- a controller in controlling communication with said air pressure differential producing apparatus, said controller being configured to select the air pressure difference dependent upon the ground speed of the planter.
An air pressure differential system for use on an agricultural planter, the planter capable of traveling at a ground speed when towed, the air pressure differential system, comprising:
- an air pressure differential producing apparatus for producing an air pressure difference;
- and
- a controller in controlling communication with said air pressure differential producing apparatus, said controller being configured to select the air pressure difference dependent upon the ground speed of the planter.
A method of operating an air pressure differential system of an agricultural planter, the method comprising the steps of:
- detecting a ground speed of the planter;
- sensing an air pressure difference generated by the air pressure differential system;
- selecting a target air pressure differential value dependent upon the ground speed;
- and
- adjusting a fan speed in an air pressure differential producing apparatus to thereby cause the air pressure difference to approximate said target air pressure differential value.
