Drop floor assembly with front and rear linkage mechanism

摘要

Embodiments relate to a harvester assembly with a feeder assembly, a bottom floor assembly, and a crop collection channel positioned therebetween. The front and the rear portion of the bottom floor assembly are capable of independent, variable movement in order to facilitate the passage of crop material through the crop collection channel with a reduced risk of clogging or plugging of the channel. Some embodiments also relate to a agricultural harvester, such as a baler or combine, with the aforementioned bottom floor assembly capable of variable movement.

主权项

1. A harvester assembly comprising:
a feeder assembly; a bottom floor assembly; a crop collection channel positioned therebetween, such crop collection channel having a depth defined by the distance between the feeder assembly and the bottom floor assembly; and a controller in operable communication with one or more valves configured for regulation of fluid flow and pressure in a hydraulic circuit; wherein the feeder assembly comprises a rotor rotatable positioned on a transverse axis between a first and a second sidewall, and a first pair of slotted guides oppositely positioned on the first and the second sidewalls; wherein the bottom floor assembly comprises:
at least a first pair of hydraulic cylinders in fluid communication with the hydraulic circuit;at least a second pair of hydraulic cylinders in fluid communication with the hydraulic circuit;a bottom floor frame comprising a first and a second framewall and at least one face extending laterally across a top portion of the bottom floor assembly, such bottom floor frame positioned opposite and proximate to the feeder assembly;one or a plurality of bottom floor plates, covering the at least one face and comprising a concave curvature that defines at least a portion of the bottom of the crop collection channel;wherein at least one of the first pair and at least one of the second pair of hydraulic cylinders is operably linked to the bottom floor frame.
