摘要： An abutment area is formed in which two belts 5, 6 are in contact with and confront each other. Link chains 23 carrying carrier rollers 24 are arranged in such a manner that carrier rollers 24 are disposed alternately on the back face of belt 5 and the back face of belt 6, in zigzags. The upper end is connected to winch 25, while the lower end is connected to weight 29. Link chains 23 are wound by winch 25, and link chains 23 are connected to the upper frame 17. When link chains 23 are stretched by weight 29, a force is given to respective belts 5, 6 through carrier rollers 24. Link chains 23 are released from upper frame 17, then link chains 23 are lowered and folded so that carrier rollers are positioned to be convenient for maintenance. Corridor for maintenance is unnecessary, and so cost is reduced.

摘要： A rectangular shield excavating machine comprises a quadrangularly tubular shield body having a space for receiving an excavated matter at the front end, a rotor disposed in the space so as to be capable of being rotated onward and backward angularly around an axis extending in the direction orthogonal to a pair of facing exterior portions of the body, and excavating means disposed in the body, drive means for rotating onward and backward the rotor angularly around the axis, and for driving the excavating means. Large gravels contained in the excavated matter are crushed by being put between the rotor and a member defining the space with the rotationally reciprocating motion of the rotor.
