Abstract
A spreader with a material divider that is adjustable to change a stream of material which flows in an arbitrary manner to the centrifugal disk(s) to achieve a desired symmetrical or asymmetrical spread pattern.
Claims16
A centrifugal spreader comprising:
- a container with a first end;
- a material transporter to transport particulate material from said container to a material divider;
- said material divider mounted below said first end, positioned to receive material therein and having a plurality of outlet orifices;
- a spinner mounted below said material divider, and positioned to receive material therein;
- said spinner having a plurality of centrifugal disks each with a throwing vane thereon;
- and
- each of said plurality of centrifugal disks being positioned below one of said plurality of outlet orifices;
- said material divider having a first internal moving part;
- wherein said first internal moving part is configured to be moved by a moveable linkage;
- said first internal moving part is moveably connected to a first actuator;
- wherein said first internal moving part is configured to direct material to:
- only a first disk of said plurality of centrifugal disks;
- only a second disk of said plurality of centrifugal disks;
- or
- both said first disk and said second disk.

A centrifugal spreader comprising:
- a container having a first end;
- a stream separator mounted below said first end and positioned to receive material therein;
- means for conveying material from said container to said stream separator;
- said stream separator having a plurality of outlet orifices;
- a plurality of centrifugal disks each positioned below one of said plurality of outlet orifices;
- and each of said plurality of centrifugal disks having a throwing vane thereon;
- and
- a flow adjuster configured for adjusting flow of material through said stream separator in a variable manner to said plurality of outlet orifices, in a manner where one outlet orifice can be deprived of material without changing said means for conveying in any manner.

A centrifugal spreader comprising:
- a container having a first end;
- a stream separator disposed below said first end and positioned to receive material therein;
- a material transporter between said container and said stream separator;
- said stream separator having a plurality of outlets;
- a plurality of rotatable members each positioned below one of said plurality of outlets;
- and each of said plurality of rotatable members having a throwing vane thereon;
- and
- a flow adjuster configured for adjusting a flow characteristic of material through said stream separator in a variable manner to said plurality of outlets, where all adjustments necessary to cause all flow from said stream separator to flow through just one of said plurality of outlets can be accomplished by making adjustments to said stream separator, and specifically excluding any need to make any adjustments to said material transporter.
