[0006]

[Action]

 According to the earth and sand removing device of this invention, when the earth and sand are accumulated in the hopper and the rotating plate is rotated by the drive unit, the earth and sand cutting blades attached to the rotating plate cut the bottom of the earth and sand and rotate. , This sand cutting blade is arranged so as to push the earth and sand outward from the center of rotation, so it works to push the cut earth and sand outward in the rotation, so the friction between the gently sloped side plate and earth and sand Combined with the reduction in force, it can be easily discharged from the lower discharge port by the conveying means. Moreover, since the rotating plate receives the load of the accumulated sediment, the load of the accumulated sediment is not placed under the rotating plate, so the load acting on the sediment cutting blade is reduced.

The gently inclined side plate 3 and the steeply inclined side plate 4 are rectangular plate members, one end of which is fixed to the open end of the box body 2 and the other end of which is a belt of a belt conveyor that constitutes the conveying means 6. It is arranged so as to be almost the same height as the surface, and both ends are fixed to both side walls 2a and 2b of the box body 2. In this embodiment, the steeply inclined side plate 4 is provided for the convenience of design, but the steeply inclined side plate 4 may also serve as the side plate of the box body 2. The inclination angle of the gently inclined side plate 3 or the steeply inclined side plate 4 is not limited, but in this embodiment, the gently inclined angle is about 30 ° and the steeply inclined angle is about 75 °. It is designed to °.

As shown in FIG. 2, the belt conveyer constituting the conveying means 6 is fitted in a concave groove portion 11 which connects the lower end of the side plate 3 having a gentle slope and the lower end of the side plate 4 having a steep slope to be integrated. As shown by the broken line in FIG. 1, it is wound around a drive shaft 12 provided in the vicinity of one side wall 2a of the box body 2 and a rotary shaft 13 provided in the vicinity of the other side wall 2b facing the side wall 2a. When the drive shaft 12 is driven by the drive motor 14, the belt conveyor constituting the transport means 6 is rotated. The conveying means 6 may be replaced with a belt conveyor, and may be a screw conveyor 15 as shown in FIG.

The drive unit 7 is an electric motor or the like, and is mounted and fixed on a fixed plate 16 which is vertically fixed to the gently inclined side plate 3. The rotor 7a of the drive unit 7 is inserted into a through hole 3a formed in the side plate 3 having a gentle inclination so as to be rotatable.

The rotary plate 8 has an elongated shape, and its center position is fixed to the rotor 7 a of the drive unit 7 via a bracket 17 with bolts or the like and is arranged parallel to the surface of the side plate 3 having a gentle inclination. The length (rotation radius) from the center of rotation to the end face is substantially equal to the distance from the center of rotation to the conveying means 6. The rotary plate 8 is not limited to the above-mentioned shape, and may be, for example, a cross shape or another shape as shown in FIG.

When the earth and sand blades 9 fixed to the lower surface of the rotary plate 8 rotate in the direction of the arrow Y shown in FIG. 5, the center line 8a of the rotary plate 8 and the center line 9a of the earth and sand blades 9 are separated. The intersecting angle α is set to be an acute angle. The inclination angle α is not particularly limited as long as it is an acute angle, but is preferably about 45 °.
