There is a problem that is damaged. Moreover, in the above-mentioned conventional example, the discharging blade 21 is a rigid body, and the rigid discharging blade 21 is connected to the spiral rigid screw portion 5.
Since the structure to engage the, it can not be referred to and along the rigid soil discharge vane 21 over substantially the entire width of the blade of the screw portion 5 for discharging soil over substantially the entire width of the blade of the screw portion 5 slightly screw portion 5 It is only possible to discharge earth and sand adhering to only the outer peripheral end of the blade. Further, in the related art, the rigid earth discharging blade 21 does not come into contact with the outer surface of the auger shaft of the screw auger 4, and therefore, there is a problem that the earth and sand attached to the outer surface of the auger shaft 7 cannot be discharged.

5 is the structure to bear. Here, in the conventional example, although the elastic force is applied to the brush 25, the elasticity of the brush 25 having elasticity is strengthened in order to enhance the removing force of the earth and sand (that is, the screw portion 5 of the screw auger 4 is formed). The movement of the brush 25 causes the brush 25 to be deformed by being pushed, and when the pressed state is released, the brush 25 needs to have an elastic force capable of elastically returning to the original state.) In this case, as described above, Since the brush 25 has a structure in which all the force applied to the brush 25 from the screw auger 4 is borne by the brush 25, the brush 25 having elasticity is worn out due to fatigue, and cannot exhibit the intended elastic force in long-term use. There is a problem in that it cannot be removed as intended because of deformation. Therefore, in the related art, it is conceivable that the brush 25 having elasticity is weakened to make it more flexible, but in this case, when the earth and sand is removed, the brush 25 is immediately deformed due to the resistance of the earth and sand, so that the brush 25 has sufficient strength. There was a problem that it was not possible to remove the earth and sand.

At this time, the projecting member 2 removes the earth and sand 6 attached to the screw auger 4.
The projecting member 2 is formed of an elastic body made of an elastic wire , and the projecting member 2 having elasticity is auger.
By increasing the protruding length of the protruding member 2 which projects from the outer periphery of the rotating body 1 than shortest distance from the outer periphery of the rotating body 1 so as to contact the shaft 7 elastically to the outer surface of the auger shaft 7 of the screw auger 4 Because of the rotation of the impeller 3, the projecting member 2 made of an elastic wire is used to rotate the screw 5 of the screw auger 4.
The sediment 6 adhered to the screw portion 5 over substantially the entire width of the blade can be scraped off by the protruding member 2, and the sediment 6 adhered to the outer surface of the auger shaft 7 is also an elastic wire.
The tip of the protruding member 2 can be scraped and removed by elastic contact . Then, even if a situation in which stones and the like contained in the earth and sand 6 are caught between the screw auger 4 and the projecting member 2 occurs, the projecting member 2 is elastically deformed because it is formed of the elastic body made of the elastic wire. Thus, the impeller 3 can be prevented from being damaged. The projecting member 2 made of an elastic wire is moved by the movement of the screw auger 4.
Is mainly converted into a force for rotating the impeller 3, and the projecting member 2 made of the elastic wire is suppressed from being deformed due to fatigue. As a result, the waist sufficient to scrape the earth and sand as an elastic body is obtained. It will be possible to use the elastic wire having it.

Are shown in the order of the operation for removing. First, in the state of FIG. 5, the screw auger 4 ascends or descends while rotating (an example of ascending is shown in the embodiment of the figure), so that an elastic protruding member located between the blades of the screw portion 5. 2a is pushed up by the blades 5a of the screw portion 5, whereby the impeller 3 rotates in the order shown in FIGS. During this time, since the screw portion 5 is rotating, the soil 6 on the blade 5a hits the projecting member 2a pushed up by the blade 5a, and the soil 6 on the blade 5a is scraped by the projecting member 2a as shown in FIG. Can be In this case, the projecting length of the projecting member 2 projecting from the outer peripheral portion of the rotating body 1 is slightly longer than the shortest distance from the outer peripheral portion of the rotating body 1 to the outer surface of the auger shaft 7 of the screw auger 4. The projecting member 2 scrapes off the earth and sand over the entire width of the blade, and the projecting member 2 having elasticity resiliently contacts the auger shaft 7 so that the projecting member 2 also scrapes off the earth and sand attached to the outer surface of the auger shaft 7. 8, 9, and 10, the tip of the elastic protruding member 2a pushed up by the blade 5a moves to the outer end side of the blade 5a. The protruding member 2b is inserted between the blade 5a and the blade 5b, and starts to scrape the soil 6 adhering to the next blade 5b and the soil 6 adhering to the outer surface of the auger shaft 7 (here, the blade 5a and the blade 5b). Represents one turn of the screw portion 5). When the protruding member 2a moves away from the tip of the blade 5a, the next protruding member 2b is pushed upward by the next blade 5b, and returns to the state of FIG.
Thereafter, the earth and sand 6 are removed while the impeller 3 rotates in the same order as in FIGS.

In addition, stones and the like contained in the earth and sand 6 lifted by the screw portion 5 are removed by the projecting member 2 and the screw portion 5.
Even if an abnormal situation of being caught between
Is formed of an elastic body instead of a rigid body, the stone can be released by the elastic deformation of the protruding member 2, and there is no hindrance to the rotation of the impeller 3, so that the impeller 3 does not break. It has become. Further, since the projecting member 2 is formed of an elastic body, the force for pushing up the projecting member 2 by the screw portion 5 is mainly converted as the rotational force of the impeller 3, and thus the projecting member 2 is pushed up by the screw portion 5. The projecting member 2 is prevented from being deformed due to fatigue due to a force. In the present invention, although the protruding member 2 has elasticity as described above,
The waist can be held as much as possible, that is, the waist can be held so as not to hinder the scraping of the earth and sand 6 by the projecting member 2.

的にできるものである。According to the present invention, an impeller is formed by radially projecting a projecting member on an outer peripheral portion of a rotating body, and a screw portion of a screw auger which moves vertically along a leader while rotating. In a screw auger discharge device in which the impeller is arranged so that at least one or more projecting members are inserted between the blades and the impeller is rotated by moving the projecting member by moving the screw portion, Lee
Attach the impeller to the shield plate attached to the lower part of the damper, form the projecting member with an elastic body made of an elastic wire, and make the auger of the screw auger from the outer periphery of the rotating body so that the elastic projecting member elastically contacts the auger shaft. Since the projecting length of the protruding member protruding from the outer periphery of the rotating body is longer than the shortest distance to the outer surface of the shaft, almost all the width of the blade of the screw part of the screw auger and the elastic wire material on the outer surface of the auger shaft The elastic body made of the elastic member elastically contacts the substantially entire width of the blades of the screw portion and the soil attached to the outer surface of the auger shaft can be reliably removed by the projecting member made of the elastic wire, and the projecting member is moved by the movement of the screw portion. Is mainly converted into the rotational force of the impeller, and as a result, deformation of the protruding member having elasticity due to fatigue can be suppressed. It is possible to form a protruding member with an elastic wire that is as stiff as possible, and to automatically and stably remove earth and sand over a long period of time. Even if this occurs, the protruding member made of elastic wire can elastically deform the stone to release the stone and rotate the impeller without any trouble. You can do it.
