FIG. 5 is a drawing showing the case where the ground at the bottom of the working chamber of the pneumatic caisson is excavated by the excavator of the present invention. In this figure, a is an excavator of the present invention, and this excavator is equipped with a pin n attached to a rotating body g attached to a traveling vehicle f running on a rail e fixed to the lower surface of a slab d on the upper surface of a working chamber c of a pneumatic caisson b. It is pivoted by. In this figure, when the rotary screw 4 of the screw conveyor 1 of the excavator a of the present invention is rotated by the drive motor 5 and the oil jack 14 is extended, the screw conveyor 1 and the excavation bucket 9 are moved by the prismatic sliding punch 12 and the sliding It moves forward (in the direction of arrow P) guided by the guide tube 13, and excavates the ground G at the bottom of the working chamber c of the caisson b with this excavation bucket 9. The soil 〇 excavated in this way is scraped in the excavation bucket 9.
1 is stirred, and by the rotation of the rotary screw turtle of the screw conveyor 1, it is transferred inside the outer cylinder 3 backwards, that is, in the opposite direction to the arrow P, and is stored in this outer cylinder. In this way, when enough sand has accumulated in the outer cylinder 3, the oil jack 14 is activated to move the excavator a backward along the sliding guide section 13, and the traveling body f is made to travel, thereby moving the excavator a. The screw 4 of the screw conveyor 1 is moved so that the ejection port 2 is above the bucket 1.
is rotated again to cause the earth and sand in the outer cylinder 3 to fall into the bucket 1 and discharged to the outside by this bucket. If the excavated soil is made of soil with a large internal frictional force, such as sand or reef, a large resistance force will act on the rotation of the screw 4 of the screw conveyor. The resistance of the excavated earth and sand may be reduced by adding it and stirring the excavated earth and sand using the scraper 11 and kneading the excavated earth and sand. To move the earth and sand excavator a, extend the oil jack i and rotate the excavator clockwise around the pin h to release the excavation bucket 9 from the ground G and move the vehicle f onto the rail e. The traveling vehicle may be moved and, at the moved position, fixed together with the excavator a on the lower surface of the slab d using a brake (not shown). In order to further rotate the excavator a, the rotating body g to which the excavator is attached is rotated by the motor k' through the pinion and the large gear m. FIG. 6 is a partially sectional plan view of another embodiment of the earth and sand excavator of the present invention, and in this figure, 1 is omitted, and items designated by numerals 18 and 18 are designated by the same numerals as in FIG. 1. It represents something similar to something. However, the embodiment of the present invention shown in FIG. 6 is similar to FIG. 1 except that oil jacks 14 for advancing or retracting the screw conveyor 1 and excavation bucket 9 are provided on both sides of the outer cylinder 3 of the screw conveyor 1. The configuration is almost the same as that of the example shown. 7th
9 to 9 are drawings showing the case where the earth and sand excavator of the present invention shown in FIG. 6 is mounted on a crawler to excavate the ground G. In each figure, a' is the earth and sand excavator of the present invention shown in FIG. 6. In the earth and sand excavator, n is a crawler, o is a side frame, q is an oil jack that rotates the excavator a', T is a turntable, and s is an oil tank and a hydraulic pump.

However, since the operation of the apparatus shown in FIGS. 7 to 9 is substantially the same as that of the apparatus shown in FIG. 5, a description thereof will be omitted. The earth and sand excavator of the present invention has the following excellent effects.

'1' Since the excavator is formed of an excavation bucket and a screw conveyor, its size can be reduced to 4 mm and is therefore suitable for excavating and discharging earth and sand in relatively narrow spaces. It is.

■ When the excavation bucket excavates the ground, the excavated soil is sequentially transferred backward by the screw conveyor, so the excavation resistance due to accumulation of excavated soil does not become large, and therefore a large excavation force can be applied to the ground.

'3} The screw blade at the rear end of the rotary screw of the screw conveyor, that is, the part facing the soil discharge port of this conveyor, is a notched screw blade, so even when this pseudo soil port is blocked by a gate, the rear end of the screw blade is notched. There is no risk that the screw will become unable to rotate due to the earth and sand filling the area.

■ スクリューコンベヤに積込まれる土砂の量が大きい

短縮することができ従って掘削能率が良好となる。
■ Since the amount of earth and sand loaded onto the screw conveyor is large, the cycle time for filling the earth and sand discharge bucket can be shortened, thus improving excavation efficiency.

[5- The excavated soil is stirred with a stirring rod installed at the tip of the rotating shaft to facilitate the introduction into the screw conveyor, and if necessary, a solution such as pentonite is added into the excavated soil. By injecting it into the ground and worshiping it with a rakaya, it is possible to improve the soil quality and make it possible to transport and scale the soil even more smoothly.
