Research of working bodies a continuous action earthworks machines

Abstract

Earthmoving equipment in highly developed countries is a leading place among self-propelled and trailed equipment for various purposes.
 The basis of such equipment are scientific and technical principles of creation of high-speed low-energy technologies and machines for destruction of natural and artificial environments (soils, rocks, mules, reinforced concrete, bricks, etc.) in various conditions (ground - road, cultivation of agricultural lands, engineering, military and emergency rescue work, cleaning of soils from pollution, reclamation, creation of trenches, canals, which underground - mining, tunnel construction, etc.
 Continuous action machines are such machines in which the working body contacts with the object of influence (soil) during the whole time of operation and all technological operations are performed simultaneously and continuously.
 Working bodies of continuous-action machines have the ability to develop strong soils without preliminary loosening
 During the continuous operation of machines, the process of their work is divided into two processes: the process of cutting soil into slaughter and the process of excavation of soil from the cutting zone, followed by its ejection from slaughter.
 The article provides an overview of new dynamic working bodies of shrew machines. The descriptions, drawings, highlighted the main disadvantages and advantages. As a result of the synthesis of existing working bodies, a new dynamic working body was developed.
