Aggregate input device using the barge of the present invention is largely made of a barge body 10, opening and closing door 20 and the opening and closing means 30.

The barge main body 10 is provided with an aggregate receiving portion 11 of the rectangular shape penetrated up and down in the center portion, the air chamber 12 is provided on both sides of the aggregate receiving portion 11 lower. In addition, the barge main body 10 is provided with a known driving device for sailing like a normal ship.

Since the aggregate receiving portion 11 is in an open state, when the aggregate is accommodated in the aggregate receiving portion, the aggregate can be stacked as high as a truck to accommodate a large amount of aggregate. The lower end of the aggregate receiving portion 11 is provided with an opening and closing door 20.

It is preferable that the inside of the air chamber 12 is inclined from the top to the bottom so that the aggregate receiving portion 11 becomes wider from the top to the bottom.

When the particle size of the aggregate is small, such as sand, aggregates received in the aggregate accommodating part 11 may generate cohesion with each other, and thus aggregate may remain in the aggregate accommodating part 11 upon release. Accordingly, when the inside of the air chamber 12 is formed to be inclined from the upper side to the lower side, the aggregate having a small particle size accommodated in the aggregate accommodating part 11 may be easily dropped to the outside of the barge main body 10.

As such, even when the particle size of the aggregate is small, such as sand, the forming force between the aggregates is reduced, so that the side shape of the aggregate accommodation portion becomes an inclined structure or an arc shape so that the aggregate contained in the aggregate accommodation portion is dropped out of the barge body. Can be facilitated.

At this time, the plate coupled to the door body 21 to close the gap between the horizontal member (21a) and the vertical member (21b) to accommodate the small aggregate such as sand in the aggregate receiving portion (11) Not shown).

The inner wall of the barge main body 10 constituting the aggregate receiving portion 11 is provided with a reinforcing portion in the form of square bars spaced at a predetermined interval to form the aggregate receiving portion 11 at the time of receiving and dropping aggregate. The inner wall of the barge main body 10 is to prevent the collision with the aggregate.

The opening and closing door 20 is located at the bottom of the aggregate receiving portion 11, is hinged rotatably to the barge main body 10 to accommodate aggregate in the aggregate receiving portion 11 or the aggregate receiving portion 11 ) Serves to open and close the aggregate contained in the drop.

The opening and closing door 20 is hinged rotatably to one side of the lower end of the aggregate receiving portion 11 of the barge main body 10, it can be one.

The opening and closing door 20 may be divided into two.

In the drawing, the opening and closing doors 20 are hinged to each of the lower ends of the aggregate receiving portion 11 of the barge main body 10 so as to be rotatable, and the portions located between the hinge pivot shafts are parallel to the hinge pivot shafts. The same size was divided into two.

The opening and closing door 20 is composed of a door body 21, the upper pillar 22 and the hinge coupling portion 23.

The door body 21 is rotated to accommodate the aggregate in the aggregate receiving portion 11 or to drop the aggregate contained in the aggregate receiving portion 11.

The door body 21 is preferably installed to be inclined downward from the lower end of the aggregate receiving portion (11).

In addition, when the aggregate is loaded in the aggregate receiving portion, the opening and closing door is inclined downward from the bottom of the aggregate receiving portion 11 can accommodate a larger amount of aggregate. In addition, since the opening and closing door is inclined downward from the bottom of the aggregate receiving portion 11, when the aggregate is dropped, the impact applied to the opening and closing door 20 can be reduced.

The upper column 22 is formed integrally with the upper portion of the door body 21 and is installed at a predetermined interval, so that the door body 21 is rotated by being combined with the opening and closing means 30.

The hinge coupling portion 23 is provided at a portion where the door body 21 and the upper pillar 22 are connected, and hinged rotatably to the barge main body 10 positioned at the lower end of the aggregate receiving portion 11. Combined.

The opening and closing door 20 is preferably the upper pillar 22 and the door body 21 to form an obtuse angle with each other inside the aggregate receiving portion (11). The obtuse angle between the upper column 22 and the door body 21 is to facilitate the operation of the opening and closing means.

In the state in which the opening and closing door 20 is closed, the aggregate is accommodated in the aggregate accommodating part 11, and in order to accommodate the aggregate, the aggregate is dropped into the aggregate accommodating part 11 by using a crane or the like to be accommodated. In this state, after moving the barge to the place where the aggregate will be dropped, the opening and closing door 20 is opened so that the aggregate contained in the aggregate accommodating part 11 is dropped at the same time.

As described above, the present invention is advantageous because the aggregate is dropped into the water by the opening of the opening and closing door 20 at the same time, where the water is strong.

In addition, the door body 21 of the opening and closing door 20 is installed in the same direction as the rotation axis direction of the door body 21, the horizontal member 21a which is spaced apart by a predetermined interval, and the door body 21 It is preferably made in a grid form so that seawater can be introduced into the aggregate accommodating part 11 by vertical members 21b installed in a direction perpendicular to the rotational axis direction and spaced apart from each other.

As described above, when the door body 21 of the opening / closing door 20 is in a lattice form and seawater is introduced into the aggregate accommodating part 11, a large amount of aggregate accommodated in the aggregate accommodating part 11 is submerged. Since it is possible to reduce the load of the aggregate accommodated in the aggregate receiving portion 11, it is possible to stably respond to the wave. In addition, by reducing the load of the aggregate, the maneuverability of the barge is improved, it is possible to reduce the capacity of the motor, engine, etc. for driving the barge. In addition, since the aggregate is dropped in a state where a large portion of the aggregate is submerged in water, the impact applied to the opening / closing door 20 during the input of the aggregate can be reduced.

In addition, the opening and closing door 20 may accommodate a larger amount of aggregate because the opening and closing door is inclined downward from the bottom of the aggregate receiving portion when loading the aggregate in the aggregate receiving portion, but the amount of aggregate is small In the state that the door body 21 of the opening and closing door 20 is horizontally positioned to allow the aggregate to be loaded in the aggregate receiving portion (11). When the door body 21 of the opening and closing door 20 is positioned in this way, a fork-shaped protrusion 21c is formed so that end portions of the door bodies 21 interlock with each other.

As shown in FIG. 9, when the aggregate is dropped into the aggregate accommodating part 11 by the opening of the opening / closing door 20, the aggregate located on the upper portion of the upper pillar 22 falls and the upper pillar 22 of the upper pillar 22 is dropped. Since the impact can be applied to the upper end of the upper column 22 to prevent the aggregate from impacting the upper end of the upper column 22 to prevent the impact of the triangular shape to fall down the inclined surface ( 22b). The impact preventing portion 22b also serves to prevent the aggregate from penetrating the rear of the upper pillar 22 when the aggregate falls.

The opening and closing means 30 serves to open and close the opening and closing door 20, and as shown in FIGS. 3 to 5 and 7 to 9, the motor 31, the rotation shaft 32, and the wire 33. And the pulley 34.

The wire 33 has one side end connected to the winding part 32a to be wound or unwound by the rotation of the rotation shaft 32, and the other end connected to the upper end of the upper column 22 to be wound or loosened. It serves to rotate the upper column (22). When the wire 33 is released, the door body 21 is rotated by its own weight, and the upper column 22 integrally formed with the door body 21 is rotated.

The pulley 34 is wound around the wire 33 and fixed to the barge main body 10 positioned behind the upper pillar 22, and the wire 33 is wound by the rotation of the rotation shaft 32. Or by pulling or loosening by loosening serves to rotate the upper column (22).

At this time, the opening and closing means 30 is installed in the upper portion of the barge main body 10 in close proximity to the upper column (22).

Thus, since the opening and closing means for driving the opening and closing door is installed above the barge, it is possible to minimize the corrosion from the sea water, and to facilitate the repair.

Although the opening and closing means 30 of the present invention has been mentioned to be operated by winding the wire 33 using the motor 31, other opening and closing means for opening and closing the opening and closing door may be used. For example, a chain may be used instead of a wire, an opening and closing means using a hydraulic or pneumatic device using a cylinder and a piston, an opening and closing means using a gear, and the like.

The upper column 22 is installed at least three places at a predetermined interval in the longitudinal direction of the opening and closing door 20, the wire 33 of the opening and closing means 30 is also installed at least three places, such as failure occurs It is desirable to be prepared in an emergency.

7 and 8 in which the opening / closing door 20 is closed, when the rotating shaft 32 is rotated by the rotation of the motor 31 and the wire 33 is released as shown in FIG. 9, the The upper column 22 of the opening / closing door 20 is rotated below the aggregate accommodating part 11 by the weight of the door body 21 around the hinge coupling part 23, and the door body 21 is opened. The aggregate accommodated in the aggregate receiving portion 11 is dropped down along the door body 21 of the opening and closing door 20 to be dropped.

As described above, the present invention closes the opening / closing door 20 by the opening / closing means 30 and ships the aggregate to be accommodated in the aggregate accommodating part 11 provided in the barge main body 10 using a crane or the like. After the barge body 10 is moved to the dropping place, the aggregate is accommodated in the aggregate accommodating part 11 by opening the opening and closing door 20 by the opening and closing means 30 without using a separate crane or the like. Since the aggregates are aggregated by dropping them into the water at the same time, it takes less time to install the aggregates, and thus there is an advantage of shortening the air.

3, 5 and 7 show a state in which the lower end of the aggregate receiving portion 11 is closed with the door body 21 in a horizontal state, and FIG. 8 shows the door body 21 inclined downward. In the state, the lower end of the aggregate receiving portion 11 shows a closed state.
