Description

[Detailed description of the invention] The present invention relates to an unloader for unloading loose objects loaded in a ship's hold.In particular, the objects are reduced to the bottom of the hold and are prevented from being carried naturally through the loading opening. The present invention relates to an unloader in which, when the situation becomes difficult, the carry-in opening is used as an input port to forcibly carry in the objects to be carried in, and all the objects to be carried in the hold can be carried out.

As shown in FIG. 1, an unloader for unloading bulk materials such as coal and grains has a bucket elevator a and a casing b surrounding the bucket elevator a, and a lower end of the casing b. A carry-in opening d is formed in the part to expose the carry-in end c of the bucket elevator a. The unloader inserts its carry-in opening d into the carried object, thereby naturally carrying the carried object into the carrying-in end c of the bucket elevator a and moving it upward.

However, with conventional unloaders,
As mentioned above, since natural loading was mainly carried out through the loading opening a, when the number of objects to be transported decreased to the bottom of the hold, the objects were no longer transported to the loading end c of the bucket elevator by natural loading. The cargo could not be unloaded. In this case, since the carrying-in opening d is wide open, even if objects to be transported are artificially fed into the carrying-in opening d, they are scattered by the rotation of the bucket, making it difficult to unload the cargo. Therefore, a separate unloading machine such as a newer is required to remove the cargo remaining in the hold, which is inconvenient.
The drawback was that it took a lot of time to work.

The present invention was devised in order to eliminate the drawbacks of the conventional unloader mentioned above, and its purpose is to be able to continue unloading work even when the cargo to be transported has decreased to the bottom of the hold, and to be able to continue unloading other cargo. To provide an unloader capable of unloading all objects to be transported in a ship's hold without requiring a machine.

In order to achieve the above object, the present invention provides an opening/closing lid that can be opened and closed at the carrying-in opening of the casing, and the casing is opened facing upward from the carrying-in end of the bucket elevator, and the opening/closing cover is closed. In some cases, a removable loading chute is provided for loading objects to be transported, and when the amount of transported objects has decreased to the bottom of the hold and it becomes difficult to carry them in naturally through the loading opening, the loading opening can be used as a loading port. The object to be transported is forcibly brought in.

A preferred embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

In FIG. 2, reference numeral 1 denotes a rectangular cylindrical casing of an unloader, and a bucket elevator 2 is disposed inside the casing along its longitudinal direction. This bucket elevator 2 consists of an endless chain 4 in which bucket belts 3 are attached at appropriate intervals, which are strung around sprockets 5 rotatably provided at the upper and lower ends of a casing 1, and the lower end thereof is connected to a carry-in end 6. The upper end is the unloading end.

A carry-in opening 7 is formed at the lower end of the casing 1 to expose the carry-in end 6 of the bucket elevator 2 to the outside of the casing. The loading opening 7 consists of a main loading opening 8 that is open along the curved lower end of the bucket elevator 2, and auxiliary loading openings 9 that are formed concentrically with the sprocket 5 on both side walls of the main loading opening 8. The main entrance 8 is provided with two-part lids 10 and 11 that can be opened and closed, and the auxiliary entrance 9 is provided with two-part lids 10 and 11 that can open and close the main entrance 8. A charging chute 12 for charging the liquid is provided in a removable manner.

The opening/closing lids 10 and 11 have their proximal ends attached to both ends of the main entrance 8 via hinges 13, and their free ends are molded into a curved shape to cover the main entrance 8, and their tips are curved. The two hinges 13 are connected to each other at the middle part of the
It has a double door structure with the fulcrum as the fulcrum. Joint flange portions 14 for connecting each other are formed at the tips of the opening/closing lids 10 and 11, and when the lids are closed, the joint flange portions 14 are connected to each other by bolts 15 as shown in FIG. has been done. Further, as a means for supporting the opening/closing lids 10, 11 in an open state, a support rod 18 is used, one end of which is attached to the casing 1 via a hinge 16, and the other end is a free end with a set screw 17.
As shown in FIG. 2, the opening/closing lids 10, 11 can be held in the open state by attaching a set screw 17 to the tip of the support rod 18 through the bolt hole of the joining flange 14.

On the other hand, the input chute 12 is made by bending a substantially semicircular plate into a curved shape and attaching both ends to the casing 1 via a hinge 19. It can be expanded from this position to a use position where the lower edge 12b is in contact with the casing 1.
In the use position shown in FIG. 3, the input chute 12 has a lower edge 12b surrounding the periphery of the auxiliary loading port 9, and an upper edge 12a facing upward from the loading end 6 to form the open loading port 20. begins to form. In order to fix the input chute 12 in the use position, a joining flange part 21 is formed on the lower edge 12b, and can be fixed to the casing 1 by bolts 22. Also,
A support rod 23 similar to the support rod 18 described above is used as a means for supporting the input chute 12 in the storage position.
is provided in the casing 1, and a joining flange portion 2 is provided at the tip of the support rod 23 as shown in FIG.
By attaching a set screw 24 through the bolt hole 1, the charging chute 12 can be held in the storage position.

Next, the operation of the above embodiment will be described.

While there are many objects to be transported in the cargo hold, the unloader is used as a normal unloader with the opening/closing lids 10 and 11 open and the input chute 12 in the storage position. In this case, the lower end of the casing 1 is inserted into the object to be transported, and the carry-in opening 7 is covered by the object to be transported, so that the object to be transported is not scattered by the rotation of the bucket, and the carry-in end 7 of the casing 1 is inserted into the object.
The unloading work will be carried out smoothly.

On the other hand, when the number of objects to be transported has decreased to the bottom of the hold, the natural transport is switched to forced transport. This can be done by closing the opening/closing lids 10, 11 and deploying the input chute 12 to the use position. and,
As shown in Figure 3, the objects M accumulated at the bottom of the hold
is forcibly carried into the carry-in end 6 of the bucket elevator 2 through the loading chute 12 using a front loader or manual power. The loading chute 1 has a main loading port 8 covered by opening/closing lids 10 and 11, and an auxiliary loading port 9 facing upward.
2, the objects to be forcibly brought in will not be blown away by the rotation of the bucket, and will be unloaded smoothly.

In this way, it is possible to continue unloading work even when the cargo to be transported reaches the bottom of the hold, and it is economical because no other unloading machinery is required, and it is possible to continue unloading work. Because you can
Work can be completed efficiently and in a short time.

In addition, the opening/closing lids 10 and 11 and the input chute 12
The means for supporting and fixing is not limited to the above embodiment, and for example, a latch or the like may be used. Furthermore, the opening/closing lids 10 and 11 may be of a continuous shutter type, and the input chute 12 may be of a removable type.

In summary, the present invention exhibits the following excellent effects.

(1) If there are many objects in the hold, it will function as a normal unloader, but if the objects have decreased to the bottom of the hold, it will cover the loading opening and forcefully transport the objects while preventing them from scattering. Since it can be operated as a device for loading and unloading cargo, it is possible to continue unloading work and unload all cargo in the hold without the need for other unloading machinery. It is valid.

(2) Therefore, it is economical because other unloading machines such as a newer are not required, and the unloading work can be carried out continuously, so the cargo handling efficiency is improved as much as possible.

(3) Since the structure is simple, it is easy to manufacture and can be easily applied to existing unloaders, making it highly versatile.
