HYDRAULIC BULLDOZER WORKING EQUIPMENT

摘要

FIELD: transport.SUBSTANCE: it can be used for earth moving, handling of various cargoes, removal of debris, etc. Invention aims at enhancing operating performances of working equipment of hydraulic bulldozer combining excavator functions at low metal input, better manufacturability and reliability. Working equipment comprises breast (1), push bars (2), truss (3) and breast drive hydraulic cylinders (10). Excavator equipment is rigidly secured at top part of rear wall of breast (1) with the help of rigid brackets (8). Said equipment is composed of two brackets (7) driven by hydromotor (9). Inside said brackets boom (6) with handle (5) are fitted while hydromotor (9) connected with bucket (4) arranged in handle coupling. Besides there are hook (15) and hydraulic cylinders for control over boom (12) and handle (11) articulated with rotary brackets (7) and boom (6) by one side and by roods with boom (6) and handle (5) by opposite side.EFFECT: higher efficiency of jobs under constricted conditions.4 dwg
