Abstract
An improved cottonseed delinter includes a magnetic tramp metal separating system in conjunction with a roll feeder. Cylinder saw lifting arms are integrally mounted for pivotal co-movement with a gratefall cover, and a gratefall cover is mounted for outward pivoting movements about a horizontal axis located in a lower portion of the gratefall cover. Makeup air for a pneumatic moting and lint conveying system is routed through delinted seeds in order to remove fly lint.
Claims19
A cottonseed delinter comprising:
- a housing;
- apparatus disposed within said housing adapted for the delinting of cottonseeds, said apparatus including at least one saw cylinder engaged with said housing for axial rotation therewithin;
- a cover mounted to said housing for movements between open and closed positions;
- and
- cylinder lift means for lifting said saw cylinder to a position for removal from the housing, said cylinder lift means being activated by moving said cover to said open position.

A cottonseed delinter comprising:
- a housing;
- apparatus disposed within said housing adapted for the delinting of cottonseeds, said apparatus including at least one saw cylinder engaged with said housing for axial rotation therewithin;
- a cover pivotably mounted to said housing for movements about a horizontal axis between open and closed positions, said cover being pivoted by operation of at least one hydraulic piston and cylinder assembly connected between said cover and said housing, and said horizontal axis extending through a lower portion of said cover, such that an upper portion of said cover pivots outwardly from said housing when said cover is moved to said open position;
- cylinder lift means for lifting said saw cylinder to a position for removal from the housing, said means being activated by moving said cover to said open position, and said cylinder lift means including a pair of substantially identical elongated cylinder lift arms extending radially from said axis and fixed at first ends thereof to said cover for coaxial pivotal movements with said cover;
- and
- said cylinder lift arms including cylinder saw engaging means at second ends thereof opposite said first ends for engaging said cylinder saw for lifting movements thereof, said cylinder saw engaging means including walls formed in pocket members defining pockets for engaging end portions of a cylinder saw shaft, with said pocket members being adjustably fixed to arm members to account for variable mounting locations of said cylinder saw shaft with respect to said housing, and said pocket members being mounted for selectively fixable sliding movements with respect to said arm members.

Cottonseed processing apparatus, comprising:
- inlet passageway walls defining an inlet passageway for unprocessed cottonseeds to be processed by the apparatus;
- tramp metal removing means disposed adjacent said inlet passageway for separating ferrous metal objects from said unprocessed cottonseeds conveyed through said inlet passageway;
- said tramp metal removing means including a magnet located to project a magnetic field into said cottonseeds such that ferrous metal objects are separated from said unprocessed cottonseeds;
- and
- a tubular roll feeder in said inlet passageway, and said magnet being located within said roll feeder.

- said tramp metal removing means including a magnet located to project a magnetic field into said cottonseeds such that ferrous metal objects are separated from said unprocessed cottonseeds;
- a tubular roll feeder in said inlet passageway, said magnet being located within said roll feeder and being stationary with respect thereto;
- said roll feeder having spaced paddles projecting radially from an outer cylindrical surface;
- said magnet projecting a semi-cylindrical field into said unprocessed cottonseeds to hold said ferrous metal objects adjacent said outer cylindrical surface;
- and
- said magnet being disposed with respect to said inlet passageway walls such that said magnet field terminates exterior of said inlet passageway walls and ferrous metal objects are released from said cylindrical outer surface exterior of said inlet passageway walls and outside said unprocessed cottonseeds.
