物を容易に揚土させることができる。 The operation of the above configuration will be explained. First, the piston rod of the hydraulic cylinder 21 is expanded and contracted appropriately to rotate the rotating cylinder 2 and the casing 5 about 20 turns on the support shaft. At the same time, when the first and second drive devices 13 and 14 are operated to rotate the casing 5 and the screw 8 in opposite directions, the relative speed between them is increased, and the bits 15 and 16 are rotated. Earth and sand are efficiently excavated or loosened, and at the same time pressure is applied to the surrounding earth and sand to facilitate work. The excavated earth and sand is pulled up by the screw 8 and thrown onto the belt conveyor 26 from the discharge port 3, and further thrown into the hopper 25 by the conveyor 26. Here, since the casing 5 and the screw 8 are rotated in opposite directions, the coefficient of friction with the earth and sand increases, and the earth can be lifted efficiently. However, when a large solid object gets caught in the inlet (intake port), it may be rotated in the same direction to remove the stuck object. Also, the screw 8 only has a center hole 9 in its center.
Since there are no obstacles in the way of soil lifting, coarse solid materials can be easily lifted.

る。 As described above, the excavating and lifting equipment of the present invention has a casing and a screw, and since the screw is coil-shaped and there is no obstacle in the center of the screw, it can easily handle even coarse solid materials. It is possible to lift soil. Therefore, so-called rough cutting work at the excavation site can be omitted, and work efficiency can be improved. Furthermore, since it is covered with a casing, there is no possibility of soil spilling or dust generation, and there is no risk of pollution problems occurring. Furthermore, the casing is rotated in the opposite direction to the screw to improve soil lifting efficiency, and the rotation of the casing is used to improve the soil lifting efficiency by using the digging bit and digging or loosening blades provided on the tip of the casing and the outer circumferential surface of the tip. The excavation or loosening action of the excavator bit can be further promoted, and soil can be excavated and lifted effectively over a wide area.
