US 5,980,382 A · Self-propelled peanut combine

Abstract

A crop harvesting combine having a body with a feeder house at its front end. The feeder house carries a detachable header which may be wider than the body and can thus be detached when moving the combine. The feeder house is vertically moveable in an arcuate path from a header ground contacting position to an elevated position. A first thrashing cylinder is in the header and a second thrashing cylinder is at the front of the combine body. The arcuate path of the feeder house has its center approximately at the rotational axis of the second thrashing cylinder so the distance between the axes of the first and second cylinders remains approximately constant as the feeder house is moved vertically. Downstream of the thrashing cylinder are a plurality of separation cylinders, at least some of which have concaves thereunder for reorienting elongate trash before being discharged.

Dependent claims

A self propelled peanut combine for picking peanut laden vines from the ground and thrashing the peanuts from the vines comprising

a combine body having first and second spaced apart sidewalls defining a flow path through said body from a front end thereof to a rear end thereof;
said body having an upper wall above said flow path and a lower wall below said flow path;
a feeder house and a header at the front of said feeder house, said header carrying a pickup cylinder for picking up peanut laden vines from the ground and said feeder house carrying a first thrashing cylinder rotatable about a first axis;
a plurality of thrashing cylinders in said body spaced along said flow path from an upstream to a downstream position for thrashing peanuts from vines, the upstream cylinder having a second axis of rotation:
means for moving said feeder house in an arcuate path between a header ground contacting position and an elevated position through an arcuate path having its center approximately at said second axis of rotation;
a pair of ground contacting front support wheels mounted from said body to extend below said lower wall, said front support wheels rotating about a front axis which is positioned rearward of said header so that said header will contact said vines prior to contact by said front wheels;
an operator's cab positioned above said upper wall and forwardly of said front wheels so as to give an operator a clear view of the vines as they enter said header.

A self propelled peanut combine for picking up peanut laden vines from the ground and thrashing the peanuts from the vines comprising

a combine body having first and second spaced apart sidewalls defining a flow path through said body from a front end thereof to a rear end thereof;
a plurality of thrashing and separating cylinders spaced along said flow path for separating peanuts from said vines;
a feeder house at the front of said body having a first thrashing cylinder mounted therein for rotation about a first axis of rotation, said feeder house being mounted for movement in an arcuate generally vertical path in relation to said body;
a header for picking peanut laden vines from the ground;
means on said feeder house for mounting said header thereon;
a second thrashing cylinder at the front of said body and rotatable about a second axis of rotation;
means for moving said feeder house and said header in said arcuate path from a header ground contacting position to an elevated position with said second axis of rotation being the approximate center for said arcuate path.

A self propelled peanut combine for picking up peanut laden vines from the ground and thrashing the peanuts from the vines comprising

a combine body having first and second spaced apart sidewalls defining a flow path through said body from a front end thereof to a rear end thereof;
a plurality of thrashing cylinders spaced along said flow path for thrashing peanuts from vines;
a plurality of separation cylinders in said body downstream of said thrashing cylinders, at least some of said separation cylinders having a concave thereunder for reorienting sticks and elongate trash to lie generally cross-wise rather than end-wise;
a feeder house at the front of said body for mounting a header for picking peanut laden vines from the ground, said feeder house including a first thrashing cylinder rotatable about a first axis of rotation;
and
fluid actuated cylinder means having a pair of arms for moving said feeder house and said header in an arcuate path so that said header moves from a ground contacting position to an elevated position;
a second thrashing cylinder at the front of said body and having a second axis of rotation;
said second axis of rotation being the center for said arcuate path for movement of said arms;
said header being detachable from said feeder house so that when said header is resting on a support, the arms can be lowered to readily disengage from said header.
