Abstract
Method for a centrifugal spreader to precisely spread particulate material across an entire field with increased application rate, swath width and driving speed by utilizing a tiered disk spinner arrangement fed by a conveyor and guided by a material divider and an adjustable chute moveable in rotation around the spinner disk to achieve a desired symmetrical or asymmetrical spread pattern.
Claims20
A centrifugal spreader comprising:
- a storage container having a discharge end;
- a conveyor to transport particulate material from said storage container to a material divider;
- said material divider mounted below said discharge end, positioned to receive material therein and having a plurality of divider outlet orifices;
- a first flow directing member;
- a second flow directing member;
- each of said first flow directing member and said second flow directing member being mounted below one of said plurality of divider outlet orifices, positioned to receive material therein and having a flow directing outlet orifice;
- a spinner mounted below said flow directing outlet orifice, and positioned to receive material therein;
- said spinner having a plurality of separated centrifugal disks;
- wherein the plurality of separated centrifugal disks include a bottom centrifugal disk and a middle centrifugal disk, each of said bottom centrifugal disk and said middle centrifugal disk includes a plurality of throwing vanes;
- wherein the plurality of separated centrifugal disks includes a top centrifugal disk along with said middle centrifugal disk and each of said top centrifugal disk and said middle centrifugal disk includes a central void configured for permitting passage therethrough of said particulate material from said first flow directing member and said second flow directing member to the middle centrifugal disk and bottom centrifugal disk;
- said first flow directing member and said second flow directing member having a plurality of internal walls;
- wherein said plurality of internal walls are formed so that a flow of said particulate material evenly distributes across region of said flow directing outlet orifices starting at the center and filling in away from center as flow increases;
- said first flow directing member and said second flow directing member are configured to move independently;
- said first flow directing member and said second flow directing member are moveably connected to a plurality of actuators;
- and
- wherein said first flow directing member and said second flow directing member are configured to selectively direct said particulate material around said spinner to said middle centrifugal disk and said bottom centrifugal disk.

- said material divider having a plurality of divider outlet orifices;
- a first flow directing member;
- and
- a second flow directing member;
- said first flow directing member and said second flow directing member being mounted below one of said plurality of divider outlet orifices, and positioned to receive material therein;
- said first flow directing member and said second flow directing member each having a flow directing outlet orifice;
- a spinner positioned below a flow directing outlet orifice;
- and
- each of said first flow directing member and said second flow directing member is configured for independently adjusting flow of material around said spinner in a variable manner.
