A universal header coupling device for a combine harvester

Abstract

The invention discloses a universal header hitching device of a combine harvester. The universal header hitching device comprises a header part of the combine harvester, a conveying trough part and ahitching mechanism for connecting the header part and the conveying trough part, the hitching mechanism comprises two hitching parts which are symmetrically arranged, and a rotating shaft for connecting the two hitching parts; each of the two hitching parts comprises a fixed seat, a connecting rod assembly, a supporting pipe, a linkage locking assembly and a handle; the handle moves up and down inthe kidney-shaped hole to drive the connecting rod assembly on the same side to move up and down, the connecting rod assembly drives the rotating shaft to rotate, and the rotating shaft drives the connecting rod assembly of the other hanging part and the handle to move synchronously; the two handles move to drive the sleeve on the same side to rotate, the sleeve drives the sliding plate to rotatewith the sleeve as the circle centers, and the shifting bolt at the lower ends of the sliding plate slides along the guide groove and drives the pin shaft to stretch into or stretch out of the mounting hole in the corresponding position of the base of the conveying groove part located between the two pin shafts, and the connection between the header portion and the conveyor trough portion is locked or unlocked.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a header and conveying trough coupling device for a combine harvester. Background technique [0002] The grain combine harvester is referred to as a combine harvester, which is a combined machine for harvesting crops. Multi-functional and multi-purpose combine harvesters often share a chassis, and the purpose of harvesting multiple crops can be met by changing the header. For example, one special header is used for harvesting wheat, another header is used for combined rapeseed harvesting, and rapeseed harvesting header and rapeseed picking header are needed for segmental harvesting of rapeseed. One chassis is compatible with multiple headers, and this device is a fast, efficient, time-saving and labor-saving device for replacing headers. [0003] In 2012, the total output value of my country's agricultural machinery industry reached 338.2 billion yuan, becoming...
