A QUICK-RELEASE FIELD CHOPPER AND ITS ATTACHMENT FRAME

摘要

A laterally attached, rear wheel supported field chopper quick-release attached to the attachment frame (24) joined to a tractor's lifting means and power transmission, said field chopper featuring, for quick-release, a power transmission receiving shaft and guiding means mounted on the side of the attachment frame (24), ie. to the left as seen from behind, for adjusting the attachment; and in which the height of the stubble is adjusted with the tractor's lifting means, which lifts/lowers the front end of the chopper (1) via the attachment frame (24) so that is corresponds to the desired stubble height; and in which power transmission to the flail shaft takes place via a belt transmission (4) or corresponding transmission immovably mounted to the side of the chopper (1). The present invention also concerns the attachment frame (24) which makes the quick-release possible. In a chopper in accordance with the invention, the quick-release is realized such that the said belt transmission (4) is positioned to the right of the chopper (1), as seen from behind, and the bearing-mounting of the power transmission receiving shaft is movable such that when attached to the attachment frame (24), the structure allows for changes in the position of the chopper (1) in relation to the attachment frame (24). At its most advantages, the said bearing-mounting is attached to the attachment counterpart (9), which can twist at the end of the traction beam and travel vertically, thus making it possible to still realize the adjustment of stubble height in the usual manner and enabling the chopper to swing according to the shape of the terrain.
