FIELD: process engineering.SUBSTANCE: invention relates to soil processing machine cutter holders, particularly, to road wheel-type trenchers. Cutter holder comprises bearing element with plug-in extending part connected thereto. Note here that said bearing element has two first and/or second bearing surfaces arranged at the angle to each other. Note also that said bearing element has the processing side with the seat for cutter directed from said plug-in extending part. The first and/or second bearing surfaces diverged from the plug-in extending parts toward the processing side. Note that two first bearing parts are arranged in the feed direction at least by separate areas ahead of the plug-in extending part. Note that two second bearing parts are arranged in the feed direction at least by separate areas behind the plug-in extending part.EFFECT: higher durability, longer life, reliable operation.38 cl, 15 dwg |
