Further, the present invention relates to a conveyor cargo handling device capable of effectively preventing a foreign load from entering a duct.

[0002]

2. Description of the Related Art In general, when transporting granular materials from a storage tank when transporting the granular materials from a storage tank, the granular materials are pulled up from the tank and transported to a main transport conveyor. The conveyor is transported to a predetermined location. For example, in a conveyor loading and unloading device in a harbor quay, a quay conveyor is installed between a ship and an unloading berth, and a bridge conveyor is connected to the quay conveyor to carry the cargo.

[0003]

[Problems to be Solved by the Invention] However, when a landing berth such as a grain berth, fertilizer or cement is located close to the harbor quay as described above, the load generated on the conveyor due to the scattering of dust generated during the discharging is reduced. There is a possibility that foreign matter may be mixed in, and this is a problem. For this reason,
A method of connecting the connected conveyors with a hood or the like is conceivable, but a fixed hood imposes a heavy load on equipment, and the connecting points between the conveyors cannot be arbitrarily changed, so that there is a disadvantage of lack of versatility.

SUMMARY OF THE INVENTION An object of the present invention is to provide a conveyor cargo handling device equipped with an inexpensive and simple dust proofing device, which enables simultaneous cargo handling at different types of transport berths such as grain berths and the like, thereby preventing dust from being mixed. It is in.

[0005]

In order to achieve the above object, a conveyor cargo handling device according to the present invention is a conveyor cargo handling device for transferring a load between conveyors, wherein a duct surrounding a load receiving conveyor is formed. While forming an opening window on the duct side wall, a strip-shaped shutter blade covering the opening window is provided in a suspended manner, and while the loading conveyor is surrounded by the duct, the front end portion is inserted through the opening window, and the loading conveyor is provided. The duct is provided with a guide rail that comes into sliding contact with the inner surface of the shutter blade and a dustproof plate that covers the opening window.

[0006]

According to the above construction, the leading end of the unloading conveyor is inserted from the duct opening window of the receiving conveyor, but a strip-shaped shutter blade is suspended from the opening window on the receiving conveyor side to cover the insertion connecting portion. Will be At this time, since the guide rail that slides on the inner surface of the shutter blade is provided on the duct side of the unloading conveyor, the shutter blade slides along the guide rail even if the unloading conveyor is moved along the unloading conveyor. Therefore, the unloading conveyor can be freely moved along the receiving conveyor while keeping the connection opening to a minimum. Further, since the dustproof plate provided inside the opening shutter closes the duct opening window on the side of the receiving conveyor, dust can be effectively prevented from being mixed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a cargo conveyor according to the present invention.

In the conveyor loading and unloading apparatus according to the embodiment, a load composed of powdery and granular materials is transferred from a bridge conveyor 10 as an unloading conveyor to a quay conveyor 12 as a receiving conveyor, and the quay conveyor 12 performs main transport. is there.

In such an apparatus, the quay conveyor 1
Numeral 2 is surrounded by a duct 14 so as to prevent the particulate matter being transported from scattering around. The duct 14 has a substantially rectangular cross section in which the top plate is inclined in one direction, and an opening window 16 is formed on one side wall surface along the transport direction. A plurality of strip-shaped shutter blades 18 are suspended adjacent to the opening window 16 so as to close the opening window 16. The shutter blade 18 is hinged at its upper edge so that it can be opened and closed, and is formed of a soft plate such as a rubber plate. However, the shutter blade 18 is configured to have a certain rigidity so that it can be opened and closed while maintaining its shape. . At an intermediate height position on the inner surface of the shutter blade 18, a guide roller 19 that comes into contact with a guide rail described later is attached.

With respect to such a conveyor configuration on the receiving side,
The unloading-side bridge conveyor 10 also has a duct conveyor structure, and transfers the granular material to the receiving conveyor 12 through the space closed by the duct 20.
The leading end of the unloading-side duct 20 is inserted from the opening window 16 of the receiving-side duct 14, and as shown in FIG. 1, the powder 21 is dropped and discharged onto the quay conveyor 12 from the discharge port on the lower surface of the leading end. I have. On the upper surface of the duct 20 of such a bridge conveyor 10, a dust-proof plate 22 of the receiving-side duct 14 is provided.
Is standing and fixed. The dust-proof plate 22 is provided on the unloading conveyor 1.
0 is inserted into the opening window 16, and the duct 20 is placed on the lower edge of the opening window 16, and is brought into contact with the inside of the upper edge of the opening window 16 so as to close the opening window 16. Is set to As shown in detail in FIG. 2, a semi-circular guide rail 24 is provided on the rear side of the dustproof plate 22.
Are fixedly supported. The guide rail 24 is formed by bending a band plate.
The unloading-side duct 2 inserted and inserted through the opening window 16 raises and holds the shutter blade 18 closing the
It does not interfere with 0. When the bridge conveyor 10 is moved along the opening window 16, the guide rails 24 move the guide rollers 19 with the opening and closing of the shutter blades 18 in order to smoothly raise the shutter blades 18 in the closed state. It is curved so as to follow the locus, and is disposed at a position where the guide roller 19 of the closed shutter blade 18 can be introduced on both side edges of the unloading side duct 20, and the height gradually increases toward the center. That is, it is curved.

When the bridge conveyor 10 is connected to the quay conveyor 12 in the conveyor loading and unloading apparatus thus configured, the tip of the bridge conveyor 10 is inserted and mounted through the opening window 16 of the duct 14 of the quay conveyor 12. At this time, the guide rail 24 provided on the duct 20 on the bridge conveyor 10 raises the shutter blade 18 of the receiving duct 14 to open the duct. However, the opening caused by the raising of the shutter blade 18 is not
And the inside of the opening shutter blade 18 is closed by a dustproof plate 22. Therefore, the powder flow 21 is prevented from leaking from the inside of the conveyor to the outside, and at the same time, being prevented from being mixed into the transport powder 21 from the outside.

The bridge conveyor 10 is moved along the transport direction of the quay conveyor 12 by changing the unloading point, and the shutter blade 18 is moved by the curved guide rail 24.
To form a minimum opening, so that there is no formation of an opening that would cause mixing when the bridge conveyor 10 moves. Therefore, in response to the movement of the bridge conveyor 10, only the position thereof becomes an opening, and the double dust-proof mechanism formed by the shutter blade 18 and the dust-proof plate 22 prevents dust from being mixed, thereby preventing foreign matter on the berth. It enables cargo handling.
