The invention relates to procedures and arrangements for preventing or releasing a blockage occurring in a flow of tree trunks (3) supplied to a wood chipper (2) via a feed hopper (1), and for securing an uninterrupted flow of timber to the chipper. The inventive procedure is characterized by providing one or several lifting means (4), which are insertable to project through openings (5) defined in the hopper (1), said lifting means (4) being inserted momentarily to raise tree trunks wedged in the hopper and/or controlled momentarily for limiting the amount of tree trunks supplied to the chipper (2).
L'invention concerne des procédés et systèmes destinés à prévenir ou à supprimer un blocage survenant dans un flux de grumes (3) venant alimenter un déchiqueteur (2) via une trémie d'alimentation (1) ainsi qu'à assurer un flux ininterrompu de bois vers le déchiqueteur. Le caractère inventif de l'invention réside dans la présence au moins d'un moyen de levage (4) pouvant être inséré pour faire saillie dans les ouvertures (5) pratiquées dans la trémie (1). Ce moyen de levage (4) est inséré temporairement pour soulever les grumes bloquées dans le déchiqueteur, et/ou commandé momentanément pour limiter la quantité de grumes fournie au déchiqueteur (2).
