Description of the invention (^) In order to achieve the above purpose, the present invention uses the earth and sand dug up by the cutting head at the front of the shield body, in After taking it into the chamber inside the front of the shield body, use the spiral conveyor to move it out of the chamber from the earth pressure shield excavator on the outer peripheral surface of the spiral blade of the spiral conveyor mentioned above. At a predetermined interval in the circumferential direction, most superhard films are installed. In addition, the closer the spiral blade is to wear, the closer to the rear side of the dice body, the smaller the distance between the superhard pieces. In addition, a plurality of protrusions may be provided on the inner peripheral surface of the casing. < Function > With the above-mentioned structure, in addition to improving the wear resistance of the spiral blade *, at the same time, it is not easy to eat small gravel between the outer circumferential surface of the worn spiral blade and the inner surface of the body, and it can prevent it from being too large. The torque acts on the screw motor. In addition, by connecting the spiral blades to the rear side of the shell and bladder, the smaller the distance between the superhard pieces, the longer the life of the spiral blades can be. Between these protrusions, a thin film of soil and sand is formed on the inner surface of the shell, so that the friction coefficient of the inner surface of the shell is greater than the friction coefficient on the surface of the spiral blade, and the soil and sand are not attached to the blade and are not driven by the flakes. Rotate and discharge to the rear, which can improve the transport efficiency. < Example > An example of the present invention will be described in detail below with reference to the third figure.

The soil and sand in the body 4a will not rotate synchronously with the spiral blade 4 b , And can carry out efficient transportation. < Effects of the invention > As described in detail above, the present invention is to install a plurality of superhard pieces on the outer peripheral surface of the spiral blade of the screw conveyor in the circumferential direction at a predetermined interval, so the outer surface of the spiral blade can be greatly reduced Attrition. As a result, it is not easy to cause the gap between the outer surface of the spiral blade and the inner surface of the shell to increase due to wear, and small gravel, etc. are eaten in the gap. Therefore, there will be no excessive torque effect The situation on the screw motor can greatly improve the durability of the chopper motor. In addition, «from entering the sand between the superhard pieces, a thin film of soil sand is formed on the outer surface of the spiral flake. This film can prevent the abrasion of the spiral blade, so it can improve the thin life of the spiral blade. The back side of the compacted earth and sand shell, the smaller the distance between the superhard pieces, the more the abrasion resistance can be improved. And * Because the superhard pieces are installed at a predetermined interval on the outer surface of the spiral blade, it is easier to operate than the method of adding wear-resistant materials on the entire outer surface of the spiral blade, and the material cost is less. It is more economical. At the same time, when the superhard film is worn out, only the superhard film needs to be replaced, so it is very easy to repair. Furthermore, the protrusions are provided on the inner surface of the shell *, and the protrusions are used to form a thin film of soil sand on the inner surface of the general body. With the thin film of soil sand, the friction coefficient of the inner surface of the shell can often be kept at a higher level than the sand attached to the spiral blade The friction coefficient is high -9- The paper size is suitable for China National Ladder Car (CNS) A4 specification (210X297mm) I--I -I 1 I---I--1 ^: Water I- n I- —I — (Please read the precautions on the back before filling in this page) V.
