摘要： PURPOSE:To generate sliding between a screw and granular materials and push granular materials upwards by a screw by installing a screw conveyer vertically. CONSTITUTION:While a rotary driver 1 is started, and its rotation is transmitted to a rotating shaft 2 to rotate the rotating shaft 2 and an expansion cover 8, compressed air 10 is supplied from a compressor 9 to the inside of the rotating shaft 2, respective air venting holes 7, and the expansion cover 8 in order, and the expansion cover 8 which is long in the axial direction is expanded outwards in the radius direction as shown in the figure to push the granular materials 11 charged in a casing 4 from a charging port 5 and transferred onto a screw 3 by a front surface of the expansion cover 8 in its rotational direction. In the case of vertical installation of a screw conveyer, sliding occurs between the screw 3 and the granular materials 11, so it is possible to push the granular materials 11 upwards by the screw 3.

The lower section of the heavy bob 17 collides with the projection 16 of a casing tube 9, and the casing tube 9 is inserted into the ground by the dropping energy of the heavy bob 17. The piston 19 is freely dropped along the cavity 18 of the heavy bob 17 after the heavy bob 17 collides with the projection 16 of the casing tube 9. The glove 8 of the glove bucket 6 is inserted into sediment 12, when the tip of the glove 8 reaches the vicinity of the tip 11 of the casing tube 9 and the piston 19 collides with the lower section of the cavity 18 of the heavy bob 17, the dropping of the piston 19 and the glove bucket 6 is stopped to complete the excavation. The glove 8 is closed, and the soil discharging process is started.

摘要： PURPOSE:To prevent the subsidence of the ground surface. CONSTITUTION:A casing tube 9 is thrust into the ground by the thrusting device of a machine main body, a wire 5 is loosened, and a glove bucket 6 with a glove 8 kept opened is lowered to the sediment in the casing tube 9. Eccentric masses 20 of a high-frequency vibration device 19 are rotated at a high frequency in opposite directions, vertical vibration force is applied to the glove bucket 6, and the glove 8 is inserted into sediment. When the glove 8 reaches the vicinity of the tip of the casing tube 9 and the jaw section 17 of the glove bucket 6 and a shock absorber 18 collide with the projection 16 of the casing tube 9, vibration is stopped, the glove 8 is closed, and the soil discharging process is started. The tip of the glove 8 of the glove bucket 6 does not precede the tip of the casing tube 9, the working face deeper than the tip of the casing tube 9 is not collapsed by the surrounding earth pressure, and the subsidence of the ground surface is prevented.

摘要： PURPOSE:To crush an object effectively by bearing a chisel with a return spring as confronting a piston fitted in an electric discharge chamber. CONSTITUTION:When a high voltage is impressed to electrodes 6, 6, spark is generated in the gap 7 between the electrodes 6, 6. As a result the water near the electrodes 6, 6 gasifies momentarily, and a pressure over several tens of thousands atoms is generated in an electric discharge chamber 8, and this pressure acts on a piston 5 as impact force so as to accelerate the piston 5 abruptly to cause running against the striking part of a chisel 3. Then this impact force applied to the chisel 3 is given to an object to be crushed such as rock bed from the tip of the chisel 3, and the object is thus crushed. At this time, the chisel 3 is returned to its initial position by the force of a return spring 2.

摘要： PURPOSE:To provide a mine surveying device for surveying the mine buried under a ground with a non-destructive means in which a micro wave is applied onto a ground surface, a behavior of temperature at the ground surface after radiation is turned into an image so as to enable a presence or non-presence of the mine to be discriminated independently of quality of the mine. CONSTITUTION:A mine surveying device is constructed to have guide rails 6 mounted on a vehicle 19; a boggie 4 which can be moved along the guide rails 6; a micro-wave radiating device 1 installed on the boggie 4 so as to radiate a micro waver 24 against a ground surface 20; an infrared ray camera 2 installed on the boggie 4 side-by-side with the micro wave radiating device 1 and receiving an infrared ray got from the ground surface 20; and a mine discriminating infrared ray imaging device 16 arranged in a control chamber 25 of the vehicle 19 so as to receive the signal from the infrared ray camera 2 and projecting the infrared ray image. With such an arrangement as above, it is possible to perform a positive surveying of the mine even if an outer shell of the mine is not made of metal.

摘要： PURPOSE:To enable a rock stratum to be cut out in a block form without any need of a cutter bit, and large torque and thrust, while causing no crack in a rock stratum around a drilling area. CONSTITUTION:A rotary shaft 1, a laser transmission tube 2 and an external slit drilling laser nozzle 5 are caused to rotate as a whole around the shaft 1. On the other hand, a laser beam 7 is condensed with a condenser 6 via reflectors 3a and 3b. The laser beam 7 after the condenser 6 irradiates around a rock stratum block 11, and the rock stratum thereof is caused to melt, thereby forming an annular external slit 8 around the block 11. After forming the slit 8, the nozzle 5 is elongated and the end thereof is inserted in the slit 8. Furthermore, a movable reflector 4 is shifted to a projection position and, then, the laser beam 7 condensed with the condenser 6 is introduced inward radially from the reflector 4. A bottom slit 9 is thereby formed and the bottom of the rock stratum block 11 is cut out.

摘要： PURPOSE:To obviate the need to exert a high rotation force and press force on a rotary shaft when a rigid rock-bed is excavated, to prevent early wear of a cutter bit and in its turn eliminate a need for frequent exchange, and to prevent the occurrent of a crack to a bed-rock around an excavating part. CONSTITUTION:An excavating device 2, excavation by which is carried out by means of cutter bits 3, is pressed against a facing 4 through a rotary shaft 1 and meanwhile, the rotary shaft 1 and the excavating devices 2 and the bits 3 are rotated. In this case, the facing 4 is irradiated with laser beams 10 from laser irradiating devices 12a, 12b, 8, and 9 rotated around the rotary shaft 1 to produce a brittle part 11 at the facing 4. The brittle part 11 is excavated by the rotating excavating devices 2 and 3, and muck 5 produced at a current time is discharged from the rear of the rock-bed excavating device to the outside of a shaft by means of a screw conveyor 6.
