摘要： PROBLEM TO BE SOLVED: To shorten time for transportation and arrangement in the field by providing a driving apparatus for supporting a feeder by means of an ascent/ descent frame and moving up and down the feeder by extending/contracting the ascent/descent frame. SOLUTION: During crushing operation, by elevating a feeder 8 by extending a hydraulic cylinder 18 and making a reciprocating frame 22 move back and forth by extending/contracting a hydraulic cylinder 23, a substance to be crushed fed in a hopper 20 by means of a hydraulic shovel, a loader etc., is made to fall down into the primary crushing part 3 and is crushed by means of a crushing roll 10 and furthermore, crushed by means of a crushing roll 11 in the secondary crushing part 4. On the other hand, during transportation, by contracting the hydraulic cylinder 18 and lowering the feeder 8 thereby, the height of the crusher is lowered. This height is the height so as to make the total height including a truck and the crusher within the limiting height for transportation when a trailer truck or a transport truck is loaded with this crusher.

摘要： PURPOSE:To select the inclination of a horizontal tunnel freely and to make it possible to excavate a hole economically by mounting guide frames capable of selecting horizontal and inclined attitudes on bearing frames loaded to the insides of casings, and arranging an excavating tool rising and falling device and a loading and unloading device. CONSTITUTION:Casings 1a and 1b are inserted into a vertical shaft A, a bit attached excavating tool 8A is held by a rotary chuck device 7b, a winch 25 is rolled down to lower, and an inclining hydraulic cylinder 15 is extended to incline guide frames 4. After that, a horizontal hydraulic cylinder 12 is advanced, and a hydraulic motor 7a of a rotary driving device 7 is forwarded to excavate. Then, the rotary chuck device 7b is opened to release the bit attached excavating tool 8A, and the guide frames 4 are set horizontally. After excavating tools 8 are lowered into holding tools 46 and 47 from the ground to hold, a grip section 8a is held by the rotary chuck device 7b, and the guide frames 4 are inclined to excavate a horizontal tunnel.

摘要： PURPOSE:To enable required deformed cross-sectional area excavation to be performed by retaining a small diameter shield hood section at a specified position with a spacer and a ringshaped member, to perform large diameter excavation, and by taking out the ring-shaped member to switch the excavation to small diameter excavation. CONSTITUTION:At the time of large diameter excavation, with a spacer 23 and a ring-shaped member 26, a small diameter shield hood section 4 is retained at a specified position. After that, a thrust load and a rotational reaction force bearing on a cutter wheel 6 supported by a central side bulk head 3 via said members are transmitted to a large diameter shield shell member 5. Besides, at the time of remodeling to a small diameter shield or after the remodeling, the ring-shaped member 26 is taken out, and between the outer periphery of the hood section 4 and the large diameter shield shell member 5, a space necessary for assembling and starting the small diameter shield is sufficiently secured. Then, large diameter excavation and small diameter excavation are gradually switched to each other, and required deformed cross-sectional area excavation is performed.

摘要： PURPOSE:To facilitate excavation of the surrounding of an underground buried pipe, by a method wherein 2 sets each of vertical inner shells, a distance between which is controllable, and about semicylindrical openable outer shells are mounted to the lower end of a cylindrical body. CONSTITUTION:A bucket mounting frame 16 is secured to the lower end of a cylindrical body 10 mounted to the forward end of the arm of an excavating device, and 2 sets of openable buckets 14 and 15 are mounted to both sides of the frame 16. Each of the openable buckets 14 and 15 is formed with about semicylindrical outer shells 14B and 15B and linear laminar inner shells 14A and 15A, and the outer shells 14B and 15B are intercoupled through an openable cylinder 25. Meanwhile, the inner shells 14A and 15A are moved and secured so that a distance therebetween is controllable. This enables easy excavation of the surrounding of an underground buried gas pipe and water pipe.
