Description

  The present invention relates to a rolling-out device, and more particularly to a rolling-out device provided with a hopper.

The construction of improving and purifying the quality of seawater by applying sand and covering sand on the soft ground of the seabed to contain soft ground such as sludge layer has been performed. Recently, in order to restore the lost natural environment, construction work has been undertaken to create tidal flats by putting earth and sand into the seabed. There are various methods for these works. For example, there is a direct opening method in which sand is thrown into the sea floor using a bottom open purge, a crane ship's clam shell, a swing method using a belt conveyor, a water carrying method using a micropump, and a tremy method (patented) Reference 1).
JP 2000-136533 A

  However, the conventional method has the following problems.

  In the swing method, sand is spread while the belt conveyor is swung from side to side, but the construction width in one swing is narrowed. Therefore, in order to spread sand in a certain area, the belt conveyor must be swung several times. There are places where sand is laid only once. Therefore, with the swing method, it is difficult to lay sand of uniform thickness on the seabed.

  In the water carrying method and the tremy method, sand is spread using a water flow, so that it is difficult to spread sand in a certain range, and therefore it is difficult to spread sand having a uniform thickness on the seabed.

  This invention is made | formed in view of this point, The place made into the objective is to provide the brewing apparatus which can spread a solid substance uniformly on the ground thinly.

The brewing apparatus of the present invention is an apparatus for spreading solid matter on the ground, and includes a hopper for spreading the solid matter from the supply port onto the ground. The supply port, two rotating axes are arranged to be substantially parallel to each other in the axial direction. Each the rotation axis, and n blades are provided so as to extend the peripheral outer surface of the shaft body from a position n divided in the circumferential direction radially outwardly. The n blades extend from one end of the shaft main body to the other end of the shaft main body while twisting along the circumferential direction on the outer peripheral surface of the shaft main body. When the line of sight is directed to the other end side, the first blade at the one end of the shaft main body is the second blade disposed at the circumferential end of the first blade and the first blade at the other end of the shaft main body. It overlaps two blades. The two rotating shafts rotate in directions opposite to each other and toward the outside, which is a direction in which the blades of both rotating shafts are separated from each other when viewed from above, so that solid matter is spread on the ground.

  The brewing apparatus of the present invention may be provided with a chute, in which case the solid material is supplied to the chute from the supply port of the hopper.

  Further, in the scooping device of the present invention, the n blades may be provided so as to extend radially outward from a position at which the circumferential outer surface of the shaft body is equally divided into n in the circumferential direction. The shaft body extends from one end of the shaft body to the other end of the shaft body, and is twisted by 1 / n round along the circumferential direction on the outer circumferential surface while reaching from the one end to the other end.

  In the scooping device according to the present invention, since the blades are provided as described above, a single blade does not block a part of the supply port, but a part of the single blade blocks a part of the supply port. Therefore, when the rotating shaft is rotated, the area of the supply port that is blocked by the blades is always substantially constant, so the area of the portion that is not blocked by the blades is always substantially constant.

Further, since the rotary shaft is kicked two settings, as compared with the case where the rotating shaft is not provided only one, can be supplied smoothly solids from a hopper to the seabed or chute.

  In the scooping device of the present invention, when the supply port is viewed from above the supply port, the blades on one of the rotation shafts are adjacent to the blades on the other rotation shaft of the adjacent rotation shafts. Is preferably twisted in the opposite circumferential direction. In such a configuration, the solid matter can be supplied to the chute more smoothly.

  In a preferred embodiment to be described later, the supply port is substantially rectangular when viewed from above, and the rotation shaft is arranged at the supply port so as to extend in the longitudinal direction of the supply port.

  In the present invention, the solid material can be spread uniformly and thinly on the ground.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following embodiment.

Embodiment 1
In the first embodiment, the configuration and operation of the brewing apparatus will be described by taking a brewing apparatus used when pulverizing coal ash granules on the seabed as an example.

  At the time of start-up, the start-up device according to the present embodiment is fixed on a trolley (not shown), and the coal ash granule is sprinkled on the seabed while moving the trolley. Thereby, coal ash granulated material can be spread over a wide range of the seabed.

  The coal ash granulated material spread on the sea floor is a mixture of about 85% coal ash and about 15% cement, which is hardened by mixing. Since such a coal ash granule has a specific gravity smaller than that of sand, it is possible to reduce the impact given to the seabed at the time of charging.

  FIG. 1 is a cross-sectional view showing a configuration of a scooping device S1 according to the present embodiment.

  This scooping device S1 includes a hopper 11. The hopper 11 temporarily stores the coal ash granules 1, 1, ..., and supplies the coal ash granules 1, 1, ... from the supply port 12 formed on the bottom surface to the seabed.

  The hopper 11 is shown. FIG. 2 is a plan view of the supply port 12 as viewed from above.

  When the supply port 12 is viewed from above, the supply port 12 is substantially rectangular as shown in FIG. The supply port 12 is provided with first and second rotary shafts 15 and 25 extending in the longitudinal direction of the supply port 12. As shown in FIG. 2, there are gaps between the periphery of the supply port and the first rotation shaft 15 and between the second rotation shaft 25 and the periphery of the supply port, so the first rotation shaft 15 and the second rotation shaft 25. Can be made to fall into the seabed through the gaps between them. Thus, since the two rotation shafts 15 and 25 are provided in the supply port 12, unlike the case where only one rotation shaft is provided in the supply port, the coal ash granule 1,1, Can be prevented from accumulating on the rotary shafts 15 and 25, and as a result, the supply to the seabed can be prevented from stagnation.

  FIGS. 3A and 3B are diagrams showing the configuration of the first and second rotating shafts 15 and 25, and FIG. 3A is a perspective view of the first and second rotating shafts 15 and 25. FIG. 3B is a view for explaining the twisting state of the blades on the first and second rotating shafts 15 and 25. Note that a to f in FIG. 3B are attached to distinguish the six blades, and for example, a [b] appears to overlap the blade 19a on one end side and the blade 19b on the other end side. It is shown that.

  The first rotating shaft 15 includes a first shaft main body 17 and six blades 19, 19,. The second rotating shaft 25 includes a second shaft main body 27 and six blades 29, 29,..., And has substantially the same configuration as the first rotating shaft 15. Therefore, only the configuration of the first rotating shaft 15 is shown below.

  As shown schematically in FIG. 3B, the blades 19, 19,... Are provided so as to extend radially outward from the outer circumferential surface at positions that divide the circumferential direction of the first shaft body 17 into six equal parts. . Each blade 19 extends from one end of the first shaft body 17 to the other end of the first shaft body 17 while twisting in the circumferential direction as shown in FIGS. 2 and 3A, and is shown in FIG. 3B. As described above, the first shaft main body 17 is twisted by 1/6 turn in the circumferential direction while reaching the other end of the first shaft main body 17. Specifically, as shown in FIG. 3B, when the other end side is viewed from one end side of the first rotating shaft 17, the first blade 19a at one end appears to overlap the second blade 19b at the other end. Further, the twisting directions of the blades are opposite to each other in the first rotating shaft 15 and the second rotating shaft 25. Thereby, coal ash granulated material 1,1, ... can be smoothly laid on the seabed.

  Here, in the case where the rotating shaft provided so that the blades extend in the axial direction of the shaft body is attached to the supply port 12, and in the case where the rotating shaft 15 according to the present embodiment is attached to the supply port 12, coal The difference of the supply condition of ash granulated material 1,1, ... is shown.

  When blades are provided extending in the axial direction of the shaft body on the rotation shaft, when the rotation shaft is rotated, the entire blade is flush with the periphery of the supply port of the hopper 11 and closes the supply port 12. There are moments and moments when no vanes block the supply port 12. Therefore, since the area of the supply port 12 that is not blocked by the blades cannot be made constant during the rotation of the rotating shaft, a certain amount of coal ash granulated material 1, 1,... Per unit time is supplied to the seabed. Can not. Furthermore, since the rotating shaft rotates while the coal ash granulated material 1, 1,... That is not supplied to the seabed exists between the blades, the rotating shaft is difficult to rotate. A heavy load is applied.

  On the other hand, in the rotating shaft 15 according to the present embodiment, the blades are twisted as described above. Therefore, when the first rotating shaft 15 is rotated, a part of one blade 19 is a peripheral edge of the supply port of the hopper 11. A portion of the supply port 12 is closed and the remaining portion of the blade 19 is disposed above or below the periphery of the supply port of the hopper 11. Thus, during rotation of the first rotating shaft 15, a part of one blade 19 always blocks a part of the supply port 12, so that the area of the portion of the supply port 12 that is blocked by the blade 19 is always the same. It becomes constant. Therefore, the area of the supply port 12 that is not blocked by the blades 19 is always constant, and as a result, the supply amount per unit time can be kept constant. Accordingly, a certain amount of coal ash granulated material 1, 1,.

  As described above, in the brewing apparatus S1 according to the present embodiment, the two rotary shafts 15 and 25 are provided in the supply port 12 of the hopper 11, so that the coal ash granulated material 1, 1,. It can be smoothly supplied to the seabed. Further, since the blades 19 and 29 are twisted by 1/6 turn in the circumferential direction while reaching from the one end to the other end of the first and second shaft main bodies 17 and 27, a certain amount of the coal ash granule 1 , 1,... Can be supplied to the seabed, and the coal ash granules 1, 1,.

<< Embodiment 2 >>
FIG. 4 is a cross-sectional view illustrating a configuration of a scooping device S2 according to the second embodiment. In the scooping device S2, the hopper 11 according to the first embodiment is connected to the chute 51 via the connecting member 59.

  The chute 51 is a plate-like member as shown in FIG. 4 and is arranged inclined from the vertical direction. Then, the coal ash granules 1, 1,... Are supplied from the hopper 11 to the chute surface 51a, fall along the chute surface 51a, and spread on the seabed. Thereby, even if it is a soft ground, coal ash granulated material 1,1, ... can be sprinkled on the seabed, without destroying the ground.

<< Other Embodiments >>
The configuration described in the first and second embodiments may be the following configuration.

  As an example of the soaking apparatus, an apparatus for spreading coal ash granulated material to the sea floor is given as an example. Needless to say, the ground is not limited to the sea floor, and the solid material is not limited to coal ash granulated material.

The hopper, the number of the blades is not limited to the above described. However, in order to smoothly supply the coal ash granulated material to the chute, it is preferable that two or more blades are attached to the shaft body.

  The n blades may be provided at a position where the outer circumferential surface of the shaft body is equally divided into n in the circumferential direction, or may be provided at a position where it is simply divided into n. When n blades are provided at a position that divides n, when the line of sight is placed on one end of the rotating shaft and the other end is viewed, the first blade on one end is the second on the other end. It only has to overlap with the wings.

  In addition, although the supply port is substantially rectangular in plan view, the shape is not particularly limited.

  The configuration shown in the second embodiment may be the following configuration.

  The relative positional relationship between the chute and the hopper is not particularly limited. For example, the chute may be arranged above the supply port of the hopper as long as the brewing device includes means for conveying the coal ash granulated material.

  The chute is plate-shaped, but irregularities that do not affect the fall of the coal ash granule may be formed on the surface.

  As described above, the present invention is useful when a solid material is provided on the ground.
