Claims

[Claims for Utility Model Registration] 1. The front body part and the rear body part are connected to each other via a center bending jack so as to be able to be bent in the center around the center bend part, and the front body part is connected to a screw through a spherical bearing. The front end of the screw conveyor is supported, and at a predetermined position on the lower side surface in the longitudinal direction of the screw conveyor, the shaft extends substantially horizontally with a length substantially equal to the stroke of the center bending jack, and has the required length in a direction perpendicular to the direction. A support pedestal having a lower surface having a width is fixed, and a pedestal capable of supporting the lower surface of the support pedestal is fixed to the rear body portion, and further, a pedestal is fixed to the rear body portion, and a pedestal is fixed to the rear body portion at a predetermined position on both left and right sides in the longitudinal direction of the screw conveyor. a fixed guide plate having a vertical surface extending substantially horizontally and parallel to the screw conveyor with approximately the same length as the stroke of the center-folding jack; A center-folding type shield digging machine characterized by being provided with a left and right positioning device having a positioning body which is adjustable so that the shield can be brought into contact with the left and right positioning device. 2. A left and right positioning device horizontally connects a predetermined position in the longitudinal direction of the screw conveyor and the rear body, and is capable of adjusting the distance between the screw conveyor and the rear body, and is capable of horizontally rotating. 2. The foldable shield digging machine according to claim 1, wherein the machine is a hydraulic cylinder.
