AGGREGATE FOR SAWING TIMBER INTO LUMBERS, CARRIAGE FOR SAWING MECHANISM MOTION, PORTABLE MOTOR SAW AND APPARATUS FOR SETTING OF LUMBER THICKNESS IN AGGREGATE FOR TIMBER SAWING

摘要

FIELD: sawing timber into lumbers. SUBSTANCE: body of sawing timber into lumbers aggregate carriage is made as rod, ends of which are engaged with both guides through detachable underframe parts providing persistence of angle between pole and guides. In the case sawing mechanism is connected with pole and pole is connected with each underframe part with capability to be detached and sawing member swinging around parallel to pole axis and with capability to control and fix its motion along pole. The aggregate and carriage have joint of carriage movement locking in direction opposite to direction of sawing and they are also provided with members of sawing member swinging locking in version with self-movable carriage. In the more preferable version guides are made in the form of single-cut beam with groove by portable motor saw directly at place of timber sawing into lumbers. The aggregate used portable motor saw has: guiding bar with sawing chain, motor and vibration-proof insulated handles equipped with device to set and keep thickness of sawing board, body with base plane, that is fixed (with capability to be removed) on the bar and / or other members of saw with formation between its base [lane and sawing chain adjustable by changeable spacers clearance. Body has windows for visual control of base surface fitting to base plane of split for boards single-cut beam, handles for manipulation in operation, protecting jacket and set of fixing members used for its fixation on changeable bars of different length. In one of versions base plane is formed by rollers loosely rotating around axes perpendicular to direction of sawing. EFFECT: improved process. 9 dwg
