US 5,842,333 A · Adjustable head assembly for cotton harvester

Abstract

A laterally adjustable harvester head assembly for a cotton harvesting machine has a width greater than the remainder of the machine, and is selectively linearly movable from a normally centered position at the front of the machine to a laterally offset position. The normally centered position is essentially laterally symmetrical relative to the remainder of the machine and is the position of choice for the head assembly during cotton harvesting operations, with the ends of the harvester head extending past the sides of the wheeled portion of the machine in order to harvest a greater number of rows simultaneously. The laterally offset position displaces the head assembly laterally from its centered position, to essentially align one end of the head assembly with the corresponding side of the harvester machine. The typical cotton harvester collects the cotton in a side dumping collector basket, and the present laterally movable harvester head allows the head assembly to be repositioned for dumping to allow the harvester machine to be positioned immediately adjacent a receiving bin for the cotton, thus improving the efficiency of the dumping operation. The movable head is secured to a vertically adjustable frame by an upper and a lower track or rail, and is actuated by a hydraulic ram which is controlled remotely from the cab of the harvester machine.

Dependent claims

A laterally movable harvester head assembly for a harvesting machine having at least harvester head attachment means laterally immovably affixed thereto and a collector bin dumping side, said assembly including at least:

a movable harvester head assembly structure having a first end and an opposite second end defining a harvester head assembly width therebetween and being wider than the harvesting machine;
a continuous, unbroken, unitary rear frame immovably affixed to said harvester head assembly structure and extending substantially the entire width thereof;
harvesting machine attachment means extending substantially from said first end to said second end of said rear frame, for movably securing said structure to the harvester head attachment means of the harvesting machine for laterally moving said structure relative to the harvesting machine;
harvesting means comprising a plurality of laterally disposed harvesting heads secured to said structure;
and
means for selectively moving said structure linearly and laterally relative to the harvester head attachment means of the harvesting machine between a working position substantially symmetrically disposed relative to the harvesting machine and a dumping position with said first end of said structure positioned substantially coplanar with the collector bin dumping side of the harvesting machine as desired.

3 more elements

A powered harvesting machine and harvester head assembly therefor, comprising in combination:

a harvester including at least a first side, a rearwardly disposed collector bin having a generally centrally disposed collection position and a dump position laterally displaced beyond said first side of said harvester, and a front end;
a laterally movable harvester head assembly structure extending forwardly from said front end of said harvester;
said harvester head assembly structure having a first end and an opposite second end defining a harvester head assembly width therebetween and being wider than said harvester;
a continuous, unbroken, unitary rear frame immovably affixed to said harvester head assembly structure and extending substantially the entire width thereof;
harvesting machine attachment means extending substantially from said first end to said second end of said rear frame, for movably securing said structure to said front end of said harvester for laterally moving said structure relative to said harvester;
harvesting means comprising a plurality of laterally disposed harvesting heads secured to said structure;
and
means for selectively moving said harvester head assembly structure linearly and laterally relative to said harvester head attachment means of said harvester between a working position substantially symmetrically disposed relative to said harvester and a dumping position with said first end of said structure positioned substantially coplanar with said harvester first side as desired.
