BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transportation device for feeding the above-mentioned powdery or granular raw material to a storage tank device for storing the raw material consisting of the powdery or granular material in a ceramics plant or the like. The present invention relates to a device for preventing the powdery particles from scattering during the feeding by using a closed bucket device.

[0002]

2. Description of the Related Art In the above-described conventional transporting apparatus, for example, as shown in FIG. 7, a raw material transported by a truck or the like is stored in a hopper 80, and the granular raw material stored in the hopper 80 is belted. The conveyor 90 or the like is used to feed the storage tank 50. Since this transportation device uses an open type belt conveyor device, there is a risk of dust pollution and the like due to scattering of powdery raw materials during the feeding operation. Further, there is a problem that several kinds of raw materials are mixed with each other during the transportation work by the belt conveyor 90 and the like. Further, the storage tank 50 has a configuration in which a plurality of storage tanks are provided for the purpose of storing several kinds of raw materials, and the raw materials are stored in the plurality of storage tanks. In order to separately feed, as shown in FIG. 7, it is necessary to install a plurality of sets of belt conveyors 20, 30.
It was necessary to combine and operate them in several stages.

[0003]

In order to solve the problems such as dust pollution and the problems such as mixing of raw materials in the case where the above-mentioned transportation method by the belt conveyor is adopted, compressed air by a compressor is used. An air transportation method is possible. However, the transportation device by this air transportation system, including the installation of the compressor,
There is a drawback in that the equipment becomes large in size, such as installation of air pipes or air-tightening measures for the entire device, and the equipment cost must be enormous. SUMMARY OF THE INVENTION It is an object (problem) of the present invention to provide a clean powder and granular material transportation device that solves such problems of equipment cost and problems of dust pollution due to dust generation.

[0004]

In order to solve the above-mentioned problems, the following measures are taken in the present invention. That is, in a granular material transport device for supplying a raw material made of granular material to a raw material storage tank provided in a plant or the like that handles the granular material, a plurality of individual granular materials for storing several kinds of granular material are stored. A storage tank device composed of a storage tank, a tower provided adjacent to the storage tank device, and a vertical movement in the tower for accommodating the powder and granules and connecting to a winch described later via a rope A bucket device, a skip loader having a winch for winding the bucket device, and a self-propelled motor for transporting the bucket device wound by the winch to a traverser described later, and the skip loader. A self-propelled mower that moves on a storage tank device and transports the bucket device in which the powder or granular material is stored onto a predetermined storage tank of the storage tank device. And traverser with motor, winding control of the winch, it was decided to employ a configuration comprising a control means for traveling control and driving control of the traverser of said skip loader.

[0005]

In the present invention, by adopting the above-mentioned constitution, the raw material consisting of the powdery or granular material is supplied (transported) to each of the storage tanks by the following procedure.

It is mounted on 2.

Next, the skip loader 2 equipped with the bucket device 1 containing such raw materials is operated based on a signal from the control means 7 and moved to a predetermined position on the traverser 3. After that, further, based on the signal from the control means 7, the traverser 3 in the state in which the skip loader 2 is mounted is operated and moved to a predetermined position on the storage tank device 5. As a result, the bucket device 1 in which the specific raw material is stored is transported onto a predetermined storage tank. Here, when the bucket device 1 is lowered, as shown in FIG.
The air valve 5 provided on each of the storage tanks as shown in FIG.
5 operates to operate the air cylinder 54 and open the gate 53 provided on each storage tank. by this,
The raw material stored in the bucket device 1 is discharged from a discharge gate 13 provided at the bottom of the bucket device 1 and stored in a predetermined storage tank.

During these series of transportation operations, the powdery granular material is batch-transported in a state where it is always stored in the closed type bucket device 1, so that it does not leak to the outside during transportation and is generated during transportation. There is no need to worry about dust. In addition, when transported to each storage bowl and stored in each storage bowl,
As shown in FIG. 3, since the work of discharging the raw material is performed in a state of being surrounded by the skirt 14 whose periphery is closed,
Even in this case, problems such as dust generation do not occur. That is, the problems such as dust pollution due to dust generation and the like are also released. Further, according to the present transportation method, the predetermined raw materials are stored in the closed bucket device 1 and are conveyed into the predetermined storage tank by the batch method, so that different raw materials are mixed in the middle of the process. There is no such thing as being lost.
