AGRICULTURAL HANDLING AND CONVEYING UNIT Russian patent published in 2000 - IPC

FIELD: agricultural engineering. SUBSTANCE: agricultural unit has tractor 1 connected through tie-rods 4-6 of suspension system to brackets 10-12 of suspender of frame 9 of hitched manipulator 2. Manipulator 2 is equipped with supports 13,14, column 15, mechanism 16 for rotating column 15, boom 17, handle 18, load-engaging hook 19, power cylinders for boom 17 and handle 18. Pull-type load platform 3 is hitched to pulling hook of manipulator through quick-release pin. Pulling hook is mounted in cavity of horizontal bar of column 15 coupled to frame 9 through vertical spindle 25 having mechanism 16 for rotating column 15. Such construction allows manipulator working zone to be increased and dynamic loading in column drive mechanism to be reduced. EFFECT: simplified construction, reduced dynamic loading exercised by agricultural unit, and enhanced reliability in operation. 3 cl, 5 dwg
