Abstract:
The present invention relates to a quick-response screw propulsion excavator, comprising a machine body and a travel driving mechanism. The quick-response screw propulsion excavator is characterized by a flat hollow hull structure of the machine body. The travel driving mechanism comprises screw rollers, support legs, a hydraulic rod, and a screw roller transmission mechanism. Two screw rollers are provided on a front portion of the machine body, and two screw rollers are provided on a rear portion of the machine body. The screw rollers are connected to the machine body by means of the support legs. The four screw rollers are connected to the travel driving mechanism to form an excavator adjustment mechanism capable of independently controlling steering and a rotation speed. A connection lug of the machine body is hinge-connected to a hydraulic cylinder sleeve. A front end of the hydraulic rod is hinge-connected to a connection lug on a lower portion of the support leg. The hydraulic cylinder sleeve is connected to an oil supply system to form an angle adjustment mechanism of the machine body and the support leg.
