LUMBERING MACHINE Russian patent published in 2001 - IPC

FIELD: wood industry, applicable in lumbering. SUBSTANCE: lumbering machine has base tractor 1 with operator's cab 2 and hydraulically-driven manipulator 3 transversely shifted relative to the cab. The hydraulically-driven manipulator has boom 4 and handle 5, with an end-effector installed on the handle end with the aid of handling mechanism 6. The end-effector has structural turning or/and rotating members. The machine has a hydraulic system provided with hydraulic pumps, distributors, hydraulic motors 8,9,10, pressure fluid feeding-discharge hydraulic lines running to the above hydraulic motors, as well as to the hydraulic motors of the end-effector structural members, whose hydraulic lines are oriented in the direction of the manipulator longitudinal axis and made in the form of sections 11, 12, 13, 14, 15 connected by fittings. The above sections are made of rigid hydraulic lines formed in a block, and flexible hydraulic lines formed in bundles. The sections of the hydraulic lines have guard members. The manipulator boom, handle, handling mechanism, end-effector have brackets for installation of the hydraulic motor turning axles. For formation of hydraulic line bundles 13 ports are provided in the brackets for attachment of boom turning hydraulic motors 8, 9 and handle. The ports are positioned between the outer surface of the boom inner contour and the turning axles of the hydraulic motors. Sections 11 through 15 of the hydraulic lines and hydraulic motors 8 through 10 are located on the side of the inner contour of the outer surface of manipulator 3, which does not need their special protection, except for the sections of the flexible hydraulic lines formed in bundles, and protection of the port in the area of the hinge joint of boom 4 to handle 5, with guard 17 provided above it. The block of section 14, mainly of the rigid hydraulic lines in the area of handling mechanism 6 is brought outside the outer lateral face of handle 5 towards operator's cab 2. The hydraulic lines of the structural members of end-effectors 7 are brought out towards the same side and connected with the aid of fittings to bulge 15 of the flexible hydraulic lines, having a protection in the form of braiding 19, and the fitting joints have a protection in the form of shields. EFFECT: optimized arrangement of structural members, enhanced reliability of machine operation. 3 cl, 9 dwg
