Cutter bar transport carriage for combine harvester, has arms pivoting on carrier frame along horizontal and vertical axes for forming, with frame and extension, quadrilateral deformed to displace supports and extension placed on supports

摘要

#CMT# #/CMT# The carriage has a fixed support (20) and a lining (30) for supporting front and rear of a cutter bar, respectively. Extension supports (60) are mounted pivoting along vertical axes (C, D) at ends of pivoting arms (40) and adjustable in inclination by a screw adjustment system. The arms pivot on a carrier frame (1) along a horizontal axis and vertical axes (A, B) such that the arms form, with the frame and an extension placed on the supports (60), a quadrilateral defined by the axes (A - D) and deformed for displacing the supports (60) and the extension that is placed on the supports (60). #CMT#USE : #/CMT# Used in an agricultural material field for being attached with a combine harvester that pulls a carriage and for transporting a cutter bar of the combine harvester, where the harvester is utilized for cutting plant e.g. colza, and collecting the cut plant and with a trailer for road transport of the harvester. #CMT#ADVANTAGE : #/CMT# The arms pivot on the carrier frame along the horizontal and vertical axes such that the arms form, with the frame and the extension, the quadrilateral deformed for displacing the extension supports and the extension, thus facilitating the displacement of the extension on the carriage by using reduced force and allowing total manual manipulation of the extension without using a cylinder and a shovel. The carriage can therefore be manufactured in a simple manner for reducing the carriage manufacturing cost. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top view of a cutter bar transport carriage in an intermediate displacement position.
