Description of the Related Art Conventionally, as a screw-type earth and sand carrier, for example, as shown in a vertical sectional view of FIG. 2, a cylindrical casing 01, a drive shaft 02 coaxially supported by the cylindrical casing 01, and a periphery thereof. It is known that the spiral surface-shaped screw is formed by the screw-04 and the screw-04.
In such an earth and sand carrier, the object 05 to be conveyed, such as earth and sand, in the casing 01 is moved by the screw 04 as indicated by the arrow 06.
When it rotates in the direction of, it moves in the direction of arrow 07.

りして矢印０７の軸方向に移動しなくなる欠点がある。
また、この現象は土砂搬送機の仰角が左程大きくなくて
も、被搬送物０５が粘土のように粘着性が大きい場合に
も発生する。However, in such a earth and sand carrier, when the elevation angle with respect to the horizon is about 40 ° or more, the weight of the transported object 05 is greater in the component applied to the screw blades 03 than the component applied to the inner surface of the casing 01. Therefore, there is a drawback that the transported object 05 circulates together with the screw blades 03 and does not move in the axial direction of the arrow 07.
This phenomenon also occurs when the material to be transported 05 has a high adhesiveness such as clay even if the elevation angle of the earth and sand carrier is not as large as the left.

That is, as shown in the vertical cross-sectional view of FIG. 3 (A), the guide plates 06 are inserted from the outside of the casing 07 so that the transported object 05 does not rotate around the screw blades 03, and the guide plates 06 are also inserted. The conveyor mechanism 08 pivotally attached to the casing 07 is rotatably mounted so that each guide plate 06 can be moved in the axial direction as the screw blade 03 rotates. Here, 09 is a screw shaft rotation motor mounted on the upper end of the casing 07.

By generating a component to be pressed against the side surface of 01, it is intended to prevent the transported object 05 from wrapping around.

(2) In the conical surface scriwl wing type shown in FIG. 3 (B), since the scriwl wing 010 has a complicated shape, it is difficult to manufacture and therefore uneconomical. Also, it is not effective for sticky soil.

As it rotates, it is conveyed vertically upward, hits the earth-discharging plate 7, is scraped off by the discharge port 6, and is discharged to the outside. During that time, high-pressure air is blown from each nozzle 4 toward the transported object 05 on the screw blades 03, so that the transported object 05 is blown away. Therefore, the circulation between the screw blades 03 and the transported object 05 is prevented. To be prevented. Further, the high-pressure air also has a function of peeling the object 05 to be conveyed from the screw blade 03. Furthermore, the air vent mechanism 5 prevents a large amount of dust-containing air from being exhausted from the exhaust port 6.
