MECHANIZED EXCAVATING TOOL Russian patent published in 1994 - IPC

FIELD: civil engineering. SUBSTANCE: one tool without changing of working members is capable of digging and backfilling a trench. Energy requirement of working process is decreased by the use of separate working members for digging and transportation of soil in combination with guiding cut-off device. This is achieved by making the soil-digging working member in the form of cutting perimeter 14 provided with vibration impact mechanism and linked with drive of chassis 1 by cranks 15 and eccentric flanges 11 while transport working member is made as inclined belt conveyor 18 mounted on frame 12 behind cutting perimeter 14 and coupled with drive of chassis 1 by mechanical transmissions. Conveyor 18 is equipped with guiding cut-off device 27 installed on conveyor frame with a provision for moving along its load-carrying belt 19. EFFECT: wider technological capabilities. 5 dwg
