Abstract
A seed coating apparatus for applying a coating fluid to seeds, consists of a seed input, a housing connected to the seed input, the housing having a seed output, a rotating seed dispersing member within the housing receiving seed from the seed input, a device adapted to produce a moving air curtain between the seed dispersing member and the seed output, whereby coating fluid applied to the seeds is kept within the seed coating apparatus by the moving air curtain, a rotating fluid dispensing member between the air curtain producing device and the seed output, and a source of coating fluid entering the housing. The rotating fluid dispensing member may preferably be a rotating bowl with apertures arranged vertically along the periphery, so that the fluid is dispensed along a vertical axis.
Claims12
A seed treating apparatus for applying a fluid to seeds, the apparatus comprising:
- a housing with an upwardly positioned seed input, an open interior below said seed input and a seed output;
- a rotating seed dispensing portion positioned below the seed input and having a substantially vertical axis;
- a fluid dispensing portion positioned below the seed dispensing portion, the fluid dispensing portion having a substantially vertical axis and comprising a rotating bowl portion having a substantially cylindrical and substantially upright rotating wall with a plurality of openings in said wall for dispensing the fluid from a vertically extending region through said wall, and
- a fluid supply duct extending to the fluid dispensing portion.
A seed coating apparatus for treating seed with a fluid, the apparatus comprising:
- a housing with an input, and open interior and an output;
- a rotating seed dispensing member having a substantially vertical axis and positioned in the open interior below said input;
- a fluid dispensing portion positioned in the open interior and comprising a substantially closed container with a substantially upright and apertured outer fluid restriction wall rotating about a substantially vertical axis;
- and,
- a fluid supply duct extending to the fluid dispensing portion and connecting to a fluid source for providing fluid to the fluid dispensing portion.
A seed coating apparatus comprising:
- a housing with an upper seed input, an open interior below said seed input, a seed output below said open interior;
- a rotating seed dispensing member below the seed input in the open interior;
- a rotating fluid dispensing portion below the rotating seed dispensing member, the fluid dispensing portion having a rotating upright outer fluid restriction wall with circumferentially and axially spaced apertures with a plurality of compartments extending radially inwardly from said fluid restriction wall for capturing and rotating the fluid in the fluid dispensing portion before the fluid is discharged from the apertures;
- and
- a fluid supply duct extending to the fluid dispensing portion and connecting to a fluid source for providing fluid to the fluid dispensing portion.
A seed treating apparatus for applying a fluid to seeds, the apparatus comprising:
- a housing with an upwardly positioned seed input, an open interior below said seed input and a seed output;
- a rotating seed dispensing portion positioned below the seed input and having a substantially vertical axis;
- a fluid dispensing portion positioned below the seed dispensing portion, the fluid dispensing portion having a substantially vertical axis and comprising a rotating substantially closed bowl portion having an upwardly extending, substantially cylindrical wall with a plurality of axially spaced openings in said wall for dispensing the fluid from a vertically extending region;
- and,
- a fluid supply duct extending to the fluid dispensing portion.
