These movable wings 10 are arranged around the hollow shaft 8 'which rotatably supports the hollow shaft 8'. The hollow shaft 8 'is coupled to the screw shaft 8 via a coupling 1 3 with a torque limiter, so * oil pressure The rotation of the motor 4 is transmitted to the hollow shaft 8 'through the coupling 13 with the torque limiter. The movable wing 10 provided on the hollow shaft 8' rotates together with the screw shaft 8. Moreover, the hollow shaft 8 'is rotatably supported. Therefore, when the movable wing 1 0 and the fixed wing 1 1 sandwich the foreign object 15, the fixed wing 1 1 does not move, and the torque of the movable wing 10 is intermediary. Μ Foreign body 15 is transmitted to the fixed shaft 1 1. Because the resistance from the fixed wing 11 is greater than the torque of the movable iio, the coupling 1 3 with the torque limiter slips off. Therefore, the screw shaft 8 Torque transmission is blocked, and has nothing to do with the rotation of the screw shaft 8, the rotation speed of the hollow shaft 8 'will be reduced, and sometimes even stop, and foreign objects 15 5 to be able to #wing

Description of invention (° |) The gate 16 between 6 is closed to prevent foreign objects 15 from falling or foreign objects 15 from being sent to the pressure pump 6. For this flat gate 18, for example, a front view (viewed from the left in Fig. 1) such as the circle 3 can be used. This flat gate 18 has a pair of shutters 19, 19 which are constituted by opening and closing jacks 20, 20 of the door. It is K. When foreign objects 15 are detected as described above, by closing these shutters 19, 19 with the gate opening / closing jacks 20, 20, the earth pressure in the chamber 3 and the screw conveyance can be prevented Soil sand in machine 5. In this embodiment, the relationship between the movable wing 1 and the fixed wing 1 1 is set according to the size of the foreign object 15 to be caught. In addition, in this embodiment, the size of the torque set by the torque limiter can be changed according to the properties of the soil and sand being transported. For example, when you want to detect foreign objects in the sand with high plastic fluidity, you can set the torque to be large or small. Furthermore, when you want to detect foreign objects in the sand with low plastic fluidity, you can set the torque to Larger. In addition, in this embodiment, the screw shaft 8 and the hollow shaft 8 'are rotatively driven by a common hydraulic motor 4. However, the drive shaft of the hollow shaft and the drive system of the rotating screw shaft 8 may be provided separately. For example, the rotation of the hollow shaft 8 'can be caused by the hydraulic motor spring through the M gear. In this case, the set torque becomes the decompression of the hydraulic motor circuit. In this configuration, when the foreign object 15 is caught, the movable wing 1 ◦k foreign object 15 receives the anti-torque from the fixed wing 11, therefore, by the safety valve provided in the hydraulic motor circuit, etc., The transmission of torque from the hydraulic motor is blocked, so that the hollow shaft -1 1- This paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X 297mm) --------- ^- ----- ir ------ ^ (Read the precautions on the back first and then fill in this page) A7 B7____ by the Ministry of Economic Affairs Central Escalation Bureau Co-operative Consumer Cooperatives A7 B7____ 5.

With this configuration, the rotation of the helical shaft 8 and the rotation of the hollow shaft 8 'are independent, and therefore, there is an effect that the optimum number of rotations can be selected separately. [Embodiment 2] Shown in circle 4 is an enlarged side view (partial defect) of the rear portion of the screw conveyor 5 incorporating the earthmoving device of another embodiment of the present invention. Figure 4 (b) is a partial cross-section nursery along the line BB in Figure 4 (a). In this embodiment, the screw shaft 8 does not rotate directly with the hydraulic motor 4 as in the first embodiment. In fact, the screw shaft 8 is provided by an oil pump motor 4 surrounded by a casing surrounding the screw conveyor 5 Rotate with a gear transmission mechanism not shown. Also, around the rear end of the screw shaft 8, a movable wing 10 is fixed along its axial direction. This example is also the case. In each case, as shown in circle 4 (b), three movable wings 10 are provided. In this embodiment, the movable * 10 is arranged at an angle as shown in FIG. 4 (a). Therefore, the rotation of the movable wing 10 generates the earth and sand conveying force. In addition, there are two rows (two pieces) of stop wings 21 that alternate with the movable wings 10. This stop "2 1 is located at the base 2 2 of the main body of the outside. This base 2 2 can be rotated in the same way as the screw shaft 8 and supported by a coupling 13 with a moment limiter.

It is M. The foreign object 15 is transported by the movable wing to the position of the stop wing 2 1 and the movable wing 1 0 And stop wing 2 1 caused by clamping. At this time, the torque of the movable wing 10 is transmitted to the stop wing 2 1 through the foreign body 15. Here, the stop wing 21 is a coupling 13 with a torque limiter and is rotatably supported by the fixed part. Therefore, when the above torque is transmitted, the stop M21 is kept at a certain anti-rotation In the moment state, the surface starts to rotate with the foreign object 1 5-the surface and the movable wing 10 and the foreign object 1 5-. It is Κ, the movable wing 10 and the stop wing 2 1 are holding the foreign object 15 while rotating while catching the foreign object 15. In this way, in the same direction as in Embodiment 1, the rotation detection sensor 14 can detect the fact that the base portion 2 2 starts to rotate, so that the presence of the foreign object 15 can be detected. In the above manner, when a foreign object 15 is detected, in the same manner as in Embodiment 1, the hydraulic motor 4 is stopped, the flat gate 18 is closed, and the soil inside the screw conveyor 5 is removed , The cover 12 is opened * and then the foreign body 15 is taken out.
