Measuring assembly for calculating the content materials of a sample removed from a stalk crop flow

The invention relates to a measuring arrangement (104) for determining the constituents of a sample taken from a crop stream sample (116). The measuring arrangement (104) includes a branch passage (106) adjoins an opening (108) in a through-flow of harvested material channel (94), and a measuring device (110) for detecting the contents of the branch passage (106) contained, from the crop stream sample taken (116).It is proposed that a processing device (126) is disposed for crushing and / or for squeezing the sample (116) in the branch channel (106) between the opening (108) and the measuring device (110).
