摘要:
A belt tensioning mechanism for use in a forage harvester comprises a cranking arm (28) pivotable about a fixed axis between two positions and connected to move an idler roller (20) into and out of contact with a belt (10) to be tensioned. A plate (46) rotatable with the cranking arm (28) cooperates with a spring biased locked lever (50) to lock the cranking arm (28) in each of the two positions.
摘要:
An agricultural harvester is disclosed having a crop processor movable into and out of the crop flow path and a service compartment arranged rearwardly of the crop flow path for accommodating an operator. A lifting mechanism 30,32 is provided in the service compartment which is movable between a first position above the crop processor when the latter is withdrawn from the crop flow path and a second position outside the service compartment.
摘要:
A forage harvester has a crop processor (16) that is movable between an operative position in which the rolls of the crop processor lie in the path of the crop flowing through the harvester and an inoperative position. In the invention, means, such as an electric motor (22) and a repositionable belt (20), are provided for rotating the rolls of the crop processor (16), when the crop processor is in the inoperative position, at a low speed sufficient to avoid vibration induced damage to the rotating components of the crop processor.
摘要:
A discharge spout (10) is described for connection at a first end (12) to a discharge tube in a forage harvester to discharge the processed crop from a mouth at its second end into a vehicle driven in use alongside the harvester. The spout (10) having an inspection opening near its first end (12), a door (18) covering and closing off the inspection opening, and at least one wear plate (40,50) separately from the door (18) and secured to the inner surface of the door (18) .
