Road paver with quick coupling apparatus for the transverse distribution device, and method
First Claim
1. A road paver for paving a subbase layer in a working direction (a), comprising:
- a machine frame,a traveling mechanism,a material hopper for receiving paving material,a paving screed for smoothing and compacting the paving material,a transverse distribution device for distributing paving material in the working direction (a) in front of the paving screed and transversely to the working direction (a), the transverse distribution device being supported at the machine frame via a support housing, anda height adjustment device for vertical adjustment of the transverse distribution device relative to the machine frame,wherein the support housing is supported at the machine frame such that the support housing is height-adjustable via a quick coupling apparatus, wherein the quick coupling apparatus comprises at least one oblong hole with an expanded insertion portion and a sliding device, wherein the sliding device can be inserted into the oblong hole through the expanded insertion portion, wherein the sliding device in the inserted state slides in the region of the oblong hole outside the expanded insertion portion-during vertical adjustment of the transverse distribution device through the height adjustment device, wherein the sliding device is supported in a form-closed manner in a direction perpendicular to the height adjustment in this region, wherein the sliding device comprises a sliding pin and a sliding anchor with an anchor plate, wherein the anchor plate has an extension transverse to the working direction which is smaller than the expanded insertion portion of the oblong hole and larger than the oblong hole in the region of the oblong hole outside the expanded insertion portion, wherein the sliding device is configured such that the sliding distance between the anchor plate of the sliding anchor and the component to which the sliding device is fastened can be set by a sliding distance adjustment apparatus, and wherein the sliding device comprises a spacer configured such that there is always at least a minimum sliding distance which essentially corresponds to the thickness of the support plate and/or the connection plate.

Abstract
A road paver includes a height adjustable auger assembly. A support housing of the auger assembly is attached to the road paver via a quick coupling apparatus that facilitates height adjustment of the auger assembly. A plurality of sliding devices are inserted into a respective oblong hole, each oblong hole includes an expanded insertion portion and a vertically extending portion. Wherein the vertically extending portion facilitates height adjustment of the auger assembly. A method of coupling the auger assembly includes inserting the sliding devices into respective oblong holes and adjusting the height of the auger assembly by moving the sliding devices between the expanded insertion portion and the vertically extending portion of the oblong holes.
