Joukkokäsittelylaitteen ohjauskytkentä

摘要

The invention relates to the coupling used to control the function of gripping elements 4,5 in a bulk treating device of a loading harvester. In the arrangement according to the invention, the valve 1 is coupled to the functional unit of the cutting organ of the loading harvester and to the functional unit of the slope of the tilting frame. This coupling operates in conjunction with the tree cutting and felling device in such a way that the gripping element 4,5, which is normally in the fixed position, is made to open at least in the felling position, whenever the rim of the saw or a similar cutting organ performs a movement during the working cycle, or whenever the harvester changes over into the lopping position, and after these functions it shuts off immediately. <IMAGE>
