Abstract
A feeder drum used in an agriculture head to force the cut crop through an opening of the head. More specifically, the feeder drum is used to produce the transition from the lateral movement of the crop through the platform to a transverse longitudinal movement (with respect to lateral movement) which directs it to the platform carrier's feeder. Even more specifically, the feeder drum comprises a plurality of fins or blades attached to a cylinder, wherein the fins contain one side with a profile describing a convex curve.
Claims15
An agricultural platform (100) used to harvest crops, said platform is configured to be supported at an open end (102) that is set up to receive severed crop materials, said platform comprising:
- a main frame (101) includes the open end, said main frame (101) extending lengthwise in a lateral direction relative to a normal direction of travel of the agricultural platform (100);
- a cutterbar assembly (201) that extends laterally across an entire transverse extent of the agricultural platform (100), wherein said cutterbar assembly (201) being disposed at a forward edge of the agricultural platform (100);
- a transition area extending from said open end (102) to said cutterbar assembly (201);
- a draper assembly (400) disposed behind the cutterbar assembly (201) to convey a cut crop material severed by said cutterbar assembly (201) inwardly toward said transition area of the agricultural platform (100);
- and
- a feeder drum (700) rotary attached to the main frame (101), the feeder drum comprising a plurality of fins (710) attached to a cylinder (720), wherein each one of said fins (710) include a front face and a rear face with respect to a rotational direction of the feeder drum (700), the front face of each fin includes convex profile (705) configured to drive the crop material in a direction perpendicular to a rotational axis (701) of the feeder drum (700) while the feeder drum rotates;
- wherein each fin (710) radially presents a top portion and a bottom portion with respect to a rotational axis (701) of the feeder drum (700);
- wherein the front and the rear faces of each fin (710) outwardly converging at the top portion in a tapered tip, the tapered tip projecting away from the cylinder;
- the feeder drum (700) is located at said transition area to receive the cut crop material from the draper assembly (400) and to carry the cut crop material rearward towards said open end (102) through which crop is fed.
An agricultural platform (100) used to harvest crops, said platform operable to be supported at an open end (102) that is configured to receive severed crop materials, said platform comprising:
- a main frame (101) operable to be mounted to the open end, said main frame (101) extending lengthwise in a lateral direction relative to the normal direction of travel of the agricultural platform (100);
- a cutterbar assembly (201) that extends laterally across substantially an entire transverse extent of the agricultural platform (100), wherein said cutterbar assembly (201) being disposed at a forward edge of the agricultural platform (100);
- a transition area extending from said open end (102) to said cutterbar assembly (201);
- a draper assembly (400) disposed behind the cutterbar assembly (201) to convey cut crop material severed by said cutterbar assembly (201) inwardly toward said transition area of the agricultural platform (100);
- and
- a rear feeder drum (144) and a front feeder drum (142) are rotably attached to the main frame (101), the rear feeder drum and the front feeder drum each comprising a plurality of fins (710) attached to a cylinder (720), wherein said fins (710) presenting a front face and a rear face with respect to a rotational direction of the rear (144) or the front (142) feeder drum, the front face of each fin includes a convex profile (705) configured to drive the material in a direction perpendicular to the rotational axes of the rear and the front feeder drums
- the fins (710) radially presenting top and bottom portions with respect to a rotational axis (701) of the feeder drum (700);
- the front and rear faces of each fin (710) outwardly converging at said top portion to a tapered tip;
- the rear feeder drum (144) is located at said transition area adjacent to the open end (102);
- the front feeder drum (142) is located at said transition area between the cutterbar assembly (201) and said rear feeder drum (144);
- both the rear feeder drum (144) and the front feeder drum (142) being configured to receive cut crop material from the draper assembly (400) and to carry the crop material rearward towards said open end (102) through which crop can be fed.
