The invention relates to a worm gear type chassis of an amphibious excavator, which comprises a body, the body comprises a hydraulic arm, a rotating unit and a power module, the power module drives the hydraulic arm and the rotating unit, and the rotating unit is arranged at the bottom end of the body to enable the body to rotate on a horizontal plane; the spiral chassis comprises a framework and two spiral transmission units, the framework is combined with the rotating unit at the bottom end of the body and extends downwards, the spiral transmission units are rotatably combined with the front side and the rear side of the bottom end of the framework respectively at the front end and the rear end, and each spiral transmission unit is provided with an external thread part and a buoyancy space; the rotation directions of all the external thread parts are oppositely arranged, and all the spiral transmission units are driven by the power module. The crawler excavator is prevented from falling into mud with high water content through buoyancy spaces of all the spiral transmission units, movement and direction change are carried out through rotation of all the spiral transmission units, and the crawler excavator can work in mud where a traditional crawler excavator cannot walk.

    本发明涉及一种水陆挖掘机蜗轮式底盘,包括一本体,其包括一液压臂、一旋转单元及一动力模组,动力模组驱动液压臂及旋转单元,旋转单元设于本体的底端使本体在水平面上旋转;及一螺旋式底盘,其包括一骨架及两螺旋传动单元,骨架结合于本体的底端的旋转单元并向下延伸,各螺旋传动单元分别以前后两端可旋转地结合于骨架底端的前后两侧,各螺旋传动单元分别有一外螺纹部及一浮力空间,各外螺纹部的旋转方向为相对地设置,各螺旋传动单元由动力模组驱动。本发明通过各螺旋传动单元的浮力空间避免陷入含水量高的烂泥之中,并通过各螺旋传动单元的旋转来进行移动及改变方向,可在传统履带挖土机无法行走的烂泥中作业。
