TRENCH ROTOR-TYPE EXCAVATOR Russian patent published in 2009 - IPC E02F5/08 E02F3/18 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering field and provided for trenching in melted soil of the I-IV category, and also in frozen grounds for engineering services, oil- and gas pipelines, drainage and can be used at contouring of foundation pis, taking out and at other works. Excavator trench rotor-type includes drive, rotor, control assembly 2 and moving mechanism. Rotor is implemented in the form of drum with tooth 14. Additionally in rotor drum it is fixed disk 6 for rotation to it transmission by means of steering circle 7, connected to rotation drive of rotor. Moving mechanism is implemented in the form of propulsive agent 8, including connected to steering circle 7 platform and three single-type double-sided hydraulic actuators, each of which contains fixed on platform casing 9 and piston 11 with rod 10, at both butts of which there are fixed hydraulic rams 12 with bearing thorned platforms 13. And drive includes pump-adjusting gear, connected by pipelines with tank 5 for working fluid and mentioned above hydraulic units. Additionally control assembly is located on platform or flooring 4 and allows manhole for entry into control assembly.

EFFECT: downsizing and productivity improvement.
