Abstract:
This invention relates to an improvement in equipment for separating the residual bark in decorticating facilities, for which, following decortication, the material is moved from the decorticating drum into a collecting funnel or hopper and from there moved on by a conveyor system, where the conveyor system is in the form of a first conveyor belt and is mounted transversely to the lower part of the hopper extending across the end of the drum, the improvement comprising joining one reversing location of the first conveyor belt by another reversing location of a second conveyor belt with an intermediate space between them, an additional roller corresponding in width to the width of the belts mounted between them, and one rectilinear guide member at each end of the additional roller to permit displacement thereof.
Abstract:
A system of substantially whole tree utilization wherein the trees are felled and subsequently slashed with the branches and top section intact to form discrete tree sections including a top section and branched bole sections, and these sections are fed into a conventional drum debarker to preferably dry and de-bark and de-branch the sections, thereby to provide branched and de-barked wood for further processing and separating bark, branches and needles. The bark and branches may be separated from each other and from the needles. The needles may be processed separately to produce chemical compounds for pharmaceutical purposes or any other use. The system of the present invention permits more economic harvesting of wood an increases the utilization of the tree by permitting utilization of not only the bole section, but also the normally unmerchandizable top and branches together with the needles.
Abstract:
A sensor mount for use with a timber-working device includes a monolithic structure having a base portion configured to be secured to a frame of a timber-working device, and a sensor mounting portion including a cavity configured to receive a contactless sensor. The cavity has a sensor mounting surface for securing the contactless sensor thereto.
Abstract:
A method of crushed ground-wood processing comprises charging the input between two relatively revolving and displaced conical surfaces with simultaneous dimension separation variation by circulating vibrations causing the surfaces to apply variable squeezing pressure and lateral or normal forces to effectively compress and rub the bark from the wood surface.
Abstract:
A hydraulic control circuit for uniform controlled movement of stripping and guiding arms in a tree delimbing apparatus. The piston rods of said cylinders are mechanically coupled to rotate tubular sleeve members with affixed stripping and guide arms between outward and inward positions. The stripping levers and guide arms open and close about a felled tree in a uniform manner for delimbing operations. A valve is provided for actuation to permit the guiding arms to be held in an open position, while the stripping arms are closed about a tree to accommodate a bent trunk.
Abstract:
A driving device comprises at least one chain (16) in the form of a closed loop. The chain is connected to at least one driving member arranged to cause the chain to orbit. Furthermore, the chain is laid over diverting members which in combination with the driving member determine the form of the loop. A rubber element (17) is arranged on the face of the chain located outermost in the loop and forms a configuration generally enclosing the chain loop. The rubber element (17) is in a driving force transmitting engagement with the chain (16) to be caused to orbit thereby. The rubber element (17) serves for engagement with for instance tree trunks over a large surface.
Abstract:
A log feed roller mechanism has a pair of parallel drive rolls; a plurality of contour-edged bars flexibly mounted at spaced intervals around the outer surfaces of each of the rolls; and, a drive mechanism for drivingly counter-rotating the rolls about their respective longitudinal axes.
