  6A and 6B show the configuration of the cutting device 4, where FIG. 6A is a front view, FIG. 6B is a cross-sectional view along line BB in FIG. It is DD sectional drawing in (A). As shown in the figure, the clipping device 4 includes a motor 24 and a rotary blade portion 26 having a rotation shaft 26 </ b> A connected to the motor 24. By rotating the motor 24, the rotary blade portion 26 rotates about the rotation shaft 26A.

  The rotary blade portion 26 includes a rotary shaft 26A extending in the horizontal direction and a cutout blade 26B extending from the rotary shaft 26A toward the outer periphery. The cutting blades 26B are attached four by four at an angle of 90 ° in the circumferential direction, and a flange plate 26C is provided perpendicular to the cutting blades 26B and the rotation axis in order to support the load acting on the cutting blades 26B. It has been.

  The cutting blade 26B is divided into a plurality of sections at predetermined intervals in the axial direction of the rotating shaft 26A, and the cutting blade 26B is attached to the rotating shaft 26A at different mounting angles in each section. That is, in this embodiment, in the state shown in FIG. 6, in the section farthest from the motor 24 (hereinafter referred to as “B cross-section”), the cutting blade 26 </ b> B has a rotating shaft 26 </ b> A as shown in FIG. Are provided so as to extend in the vertical and horizontal directions. As shown in FIG. 6C, the mounting angle in the section adjacent to the motor 24 side of the B cross section (hereinafter referred to as the C cross section) is shifted by 30 ° with respect to the B cross section. The mounting angle in the section adjacent to the motor 24 side of the C cross section (hereinafter referred to as the D cross section) is shifted by 30 ° with respect to the C cross section, that is, shifted by 60 ° with respect to the B cross section. It has become. Further, the mounting angle in the section adjacent to the motor 24 side of the D cross section is shifted by 30 ° with respect to the D cross section, that is, the cut blade 26B is in the vertical direction and the horizontal direction as in the B cross section. It is in an extended state. Thus, in this embodiment, the B cross section, the C cross section whose mounting angle is shifted by 30 ° with respect to the B cross section, and the D cross section where the mounting angle is shifted by 60 ° with respect to the B cross section are repeatedly arranged. It is out. As in the present embodiment, the rotating blade portion 26 is configured from a plurality of portions having different attachment angles of the cutting blade 26B, thereby averaging the load applied to the motor 24 regardless of the rotating angle of the rotating blade portion 26. be able to. Further, by using the rotary blade portion 26 in this way, even when the rotation axis of the rotary blade portion such as the rear portion of the barge 1 is provided with an inclination, it is possible to reliably cut out the particulate matter. it can.

  As shown in FIG. 1, the rear part of the conveyor 6 is inclined upward, and the rear end part is located above the rotation center of the spreader 8. The spreader 8 extends obliquely upward and can rotate around the lower end.

Hereinafter, the operation | work which stores coal in the barge ship 1 provided with the discharge device of this embodiment, and unloads the stored coal to the adjacent barge ship 1 is demonstrated.
First, when storing coal in the barge 1 provided with the discharge device of the present embodiment, the closing plate 14 is rotated to close the opening 18 formed below the side wall portion 12A. Thus, coal can be stored in the storage part 2 by throwing coal into the storage part 2 from above with the opening 18 closed by the closing plate 14.
When unloading the stored coal to the revetment, first, the barge 1 is put on standby along the revetment, and the spreader 8 is rotated so that the tip is located on the revetment.

  Then, the closing plate 14 is rotated to open the opening 18. When the opening 18 is opened, coal flows out from the storage unit 2 through the opening 18 to the receiving unit 16. The coal that has flowed out to the receiving part 16 in this way is deposited on the receiving part 16 in a mountain shape. Then, the coal accumulated in the mountain shape reaches a height at which the opening 18 is blocked, and the coal is stabilized in a state where the opening 18 is blocked and does not collapse and is independent. Thereby, the outflow of coal from the storage part 2 through the opening 18 is blocked.

  At this time, the angle of the closing plate 14 may be adjusted so that the width for opening the opening 18 is small when the amount of coal stored in the storage unit 2 is large and is large when the amount of coal is small. As a result, a certain amount of coal is discharged to the receiving portion 16 regardless of the amount of stored coal.

  In such a state, the motor 24 of the cutting device 4 is driven to rotate the rotary blade portion 26. As the rotary blade portion 26 rotates, the coal that has fallen onto the receiving portion 16 from the opening 18 is scraped onto the ship bottom conveyor 6. When coal is scraped from the receiving portion 16 by the cutting device 4, approximately the same amount of coal as the scraped coal flows out from the opening 18 again. For this reason, by rotating the rotary blade portion 26 at a constant speed, a substantially constant amount of coal per hour can be continuously dropped onto the ship bottom conveyor 6.

  In this way, the coal that has fallen onto the ship bottom conveyor 6 falls onto the spreader 8 when sent to the downstream end by the ship bottom conveyor 6. And the coal which fell on the spreader 8 is conveyed to the edge part of a downstream side, and is deposited on a revetment.

  As described above, according to the present embodiment, since one side wall portion 12B extends below the other side wall portion 12A, the opening 18 opens sideways or obliquely downward. Even when the storage amount of the storage unit 2 is large, the load of the granular material acting on the cutting device 4 can be reduced, and the cutting device 4 is driven smoothly. Furthermore, since the cutting device 4 includes the rotation shaft 26A and the cutting blade 26B that rotates about the rotation shaft, it is possible to continuously discharge a fixed amount of particulate matter.

  Further, the rotary blade portion 26 is divided into a plurality of sections in the axial direction of the rotary shaft 26A, and the mounting angle of the cutout blade 26B with respect to the rotary shaft 26A in each section is the rotation shaft 26A of the cutout blade 26B in other sections. Therefore, the load applied to the motor 24 can be averaged regardless of the angle of the rotary blade portion 26.

  Furthermore, since the attachment angle of the cutting blade 26B in each section is shifted by 30 °, 30 °, 60 °, and 90 ° with respect to the reference section, the mounting angle of each cutting blade 26B is uniform. Therefore, the load applied to the motor 24 can be further averaged. Thus, running costs such as fuel costs can be reduced by reducing the load on the drive power source such as a motor.

In addition, by adjusting the width of the opening 18 by the closing plate 14, even if it is a granular material having a different size or weight, or a storage amount of the granular material is changed, a substantially constant amount of the granular material is always received. Can be dropped on the part.
Furthermore, since it is not necessary to scrape the granular material with a bulldozer or the like in the storage unit, time and fuel costs can be reduced.

  Hereinafter, the case where the discharge apparatus of 2nd Embodiment is applied to the transfer ship for transferring granular materials, such as coal, from a large barge ship to a seawall or another barge ship is demonstrated. In addition, about the component similar to 1st Embodiment, the same number is attached | subjected and description is abbreviate | omitted.

The fifth conveyor 114 has an upstream end connected to an intermediate portion of the fourth conveyor 112, and a downstream end positioned on the rotation center of the spreader 116. With this configuration, the granular material dropped on the first conveyor 106 is conveyed to the spreader 116 via the first to fifth conveyors 106, 108, 110, 112, 114, and a desired place is obtained by the spreader 116. Can be dropped.

  As shown in FIG. 9, the discharge device 102 is installed on a gantry 120 having wheels 122 at the bottom. Similarly to the first embodiment, the discharge device 102 includes a storage unit 2, a cutting device 4, and a conveyor 6.

Then, the spreader 116 is rotated so that the tip is positioned above the storage section of the barge ship. Further, the discharge device 102 is arranged so that the downstream end of the conveyor 6 of the discharge device 102 is positioned above the first conveyor 106.

  Next, the closing plate 14 is rotated to open the opening 18, and the coal on the revetment is dropped into the storage unit 2 of the discharge device 102 by the backhoe 104. Then, the motor 24 of the cutting device 4 is driven to rotate the rotary blade portion 26.

  Thereby, the coal dropped into the storage unit 2 is discharged from the opening 18 onto the receiving unit 16, and the coal discharged into the receiving unit 16 is dropped onto the conveyor 6 by the cutting device 4. The coal dropped on the conveyor 6 is transported by the conveyor 6 and dropped on the first conveyor 106. Then, the coal is conveyed to the spreader 116 via the first to fifth conveyors 106, 108, 110, 112 and 114, and dropped onto the barge by the spreader 116.
