Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flexible conveyor that mainly transports mineral products, sand and gravel, silt and the like in water over a long distance.

[0002]

[Prior art]

 Belt conveyors, skit conveyors, bread conveyors, bucket conveyors, screw conveyors, and the like are known as conveyors for transportation.

[0003]

[Problems to be solved by the device]

 Although there are various kinds of conveyors as described above, the transportation distance is 200 to 300 m on land. Furthermore, underwater conveyors have not been developed except for special applications.

An object of the present invention is to provide a flexible conveyor device that can carry water for a long distance.

[0005]

[Means for Solving the Problems]

 The flexible conveyor device of the present invention has a flexible outer cylinder formed by combining a hard tube having high abrasion resistance and a flexible joint, and the outer cylinder is used for the outward path and the return path. An outer cylinder constitutes one system, at least one wire or chain movable in the outer cylinder, and fixed to the wire or chain and slidably contacting an inner peripheral surface of the outer cylinder at a peripheral edge portion. A plurality of buckets having a lip portion and a drive device for driving the wire or chain are provided, and the drive device is provided with a horizontally arranged wire hole, and the wire hole is provided in the wire hole or the wire hole. The chain is wound half way around and a plurality of cutouts for accommodating the plurality of buckets are formed.The wire wheel is fixed to the output shaft of the reduction gear, and the reduction gear is connected to the motor via a coupling. Has been Reduction gear and the motor is characterized that you have that are fixed on the base.

Here, as the hard tube forming the outer cylinder, for example, a hard tube made of metal or porcelain having high wear resistance is adopted, and by combining this with a flexible joint, it has flexibility as a whole. Can be configured to. However, it is also possible to form the outer cylinder into a cylinder, a rectangular cylinder, or a rectangular cylinder by using a soft and highly wear-resistant plastic material, and flange-connect such plastic tubes. Further, it is preferable that the outer cylinder is fixed to the bottom of the water with a hold rope and a weight and installed.

Further, it is preferable that the lip portion is formed of a wear-resistant synthetic rubber material.

In the practice of the present invention, when the outer cylinder is installed over a long distance, the product conveyed in the outer cylinder from the upstream side is transferred to another system on the downstream side at a proper place on the bottom of the water. It is preferable to provide a relay station for supplying the gas into the outer cylinder of the above and further carrying it inside.

Here, when the flexible conveyor device of the present invention is installed in water, the flexible joint portion is prevented from being deformed by water pressure (outside water pressure), and the flexible joint is deformed by the deformation. In order to prevent the sliding resistance of the lip portion of the bucket from increasing, it is preferable that the internal pressure be increased by filling water from the inlet / water injection port formed in the outer cylinder or the flexible joint. . Alternatively, in place of the water injection mechanism, it is preferable to provide a pressurizing device for applying pressure by the water head into the outer cylinder so that the flexible joint is not deformed against the external water pressure acting thereon.

The outer cylinder can be laid on the water surface. In this case, it is preferable to support the outer cylinder with a float.

As described above, the outer cylinder is the outer cylinder for the outward path, that is, the outer cylinder on the side where the bucket for conveying the conveyed object slides, and the outer cylinder for the return path, that is, after the conveyed article is conveyed. A so-called "empty" bucket and a return outer cylinder on the side where the bucket moves, constitute one set or one system of outer cylinder. However, depending on the application, it is possible to omit the return cylinder.

In the flexible conveyor configured as described above, the outer cylinder is aligned with the terrain, for example, along the seabed between facing shores, fixed with hold ropes and weights, and if necessary, put in place. Establish a relay station. Then, a driving device is installed on one shore and a driven device is installed on the other shore, and a plurality of buckets are fixed to the wire or chain at a predetermined pitch.

Then, by accommodating a corresponding number of the buckets in a plurality of notches formed in the wire hole of the drive device, the wire or chain is wound around the wire hole by half a turn. When the motor is driven in that state, the rotation is transmitted to the speed reducer via the coupling, is transmitted from the output shaft of the speed reducer to the wire wheel, and is transmitted to the wire or chain. .

When the outer cylinder is laid in water, the outer cylinder and the relay station are filled with fresh water from the inlet / water injection port to secure the inner diameter of the outer cylinder, and then the drive device is operated to operate the bucket. It is carried by.

Here, the outer cylinder of the present invention in which a hard pipe is joined with a flexible joint to provide flexibility can be freely deformed according to the terrain on which the conveyor is laid, so that the outer cylinder erection work is extremely difficult. It will be easy.
