Description

[Detailed Description of the Invention] The present invention relates to a powder container that can efficiently transfer powder and granule materials.

Generally, powder and granular materials are transported using a combination of crane packets, trucks, belt conveyors, and other equipment.

For example, when granular materials are loaded onto a transport facility such as a ship that is located away from a storage site, the granular materials at the storage site are loaded in bulk onto trucks or belt conveyors, and are transported to the vicinity of the ship and piled up.

Then, the piled-up powder and granular material is loaded onto a ship using a crane packet.

However, the above-mentioned handling of powder and granular materials not only has extremely low working efficiency, but also has the drawback of requiring a vast facility for stacking powder and granular materials near the ship.

The present invention is a powder container that can eliminate the various drawbacks in transporting powder and granule materials.

The present invention is a hollow box-like body in which at least one side surface connected to the bottom surface has an inclined surface extending outward from the bottom surface in the vertical direction, and a loading port is provided at the top, and the upper end of the inclined surface and the upper end of the inclined surface are provided. Provide an outlet between the hollow box-like body and the surface connected to the hollow box-like body, and place at least three hanging tools around the hollow box-like body, at a projection point created by projecting the center of gravity of the hollow box-like body onto the bottom surface of the hollow box-like body. but,
This powder container is located within a projected polygon formed by projecting onto the bottom surface of a convex polygonal hollow box-like body formed by connecting the points where the hangers are located.

If the powder container of the present invention (hereinafter simply referred to as a container) is used for cargo handling, there is no need to deposit powder and granules in conventional powder and granule cargo handling, improving work efficiency and eliminating the need for a depositing area. This results in various advantages such as:

That is, a container loaded with powder and granular material from a loading port at a powder storage facility is placed on the loading platform of a truck, for example, and transported near a ship.

Here, a robe is placed on the container's hanging equipment, and the container is lifted up with a crane device and moved onto the ship.
By tilting the container so that the discharge port is facing downward, powder and granular materials can be loaded and unloaded.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing one embodiment of the container of the present invention.

In FIG. 1, a container 1 has an inclined surface 2 in which one side surface connected to the bottom surface extends outward from the bottom surface in the vertical direction.
A hollow box-like body having a loading port 5. A discharge port 4 and a hanger 6 are provided, respectively.

The sloping surface 2 is for quickly discharging the powder from the container along the sloping surface when the container is tilted so that the discharge port 4 is at the bottom. It is preferable that A be larger than the angle of repose of the granular material being handled.

Further, the shape of the inclined surface can take various shapes such as a flat plate, a curved shape, and a multifaceted shape depending on the shape of the discharge port which will be described later.

In FIG. 1, the discharge ports are provided opposite each other along the entire length, so that the inclined surface has a flat plate shape.

On the side surface having an inclined surface, an inclined surface 2 connected to the bottom surface
Although there is no particular restriction on the proportion occupied by the powder, it is preferable to make it approximately half of the side surface from the viewpoint of stabilizing the container when discharging the powder or granular material.

The loading port 5 is provided at the top of the box-like body, that is, generally above the vertical center of the box-like body, and more preferably on the top surface, from which powder and granules are loaded into the container.

The location of the loading port is determined as appropriate depending on the shape of the container.

Further, the shape is not particularly limited, but circular, rectangular, etc. are common.

The discharge port 4 is connected to the upper end of the inclined surface 2 and the surface 3 connected to the inclined surface 2.
established between.

The surface 3 that connects to the slope 2 is the remaining side of the side surface when the slope occupies a part of one side of the box-like body, and the surface 3 that connects to the slope 2 is the slope that occupies a part of one side of the box-like body. , the upper surface of the box-shaped body corresponds to it.

In the former case, the surface 3 connected to the inclined surface 2 may be formed, for example, vertically, but generally, as shown in the figure, it is preferable to make the surface 3 in the opposite direction to the inclined surface to prevent the powder and granules in the container from being formed. It is preferable because it can be efficiently discharged.

The discharge port only needs to be open to allow the powder to pass through, and its shape is generally a 9-circular shape with a slit extending the entire length, a square shape, a polygonal shape, etc., depending on the usage of the container. be selected as appropriate.

In this case, in order to prevent the powder inside the container from flowing out from the outlet when the container is transferred, it is preferable that the outlet is provided such that its lower end, which is closer to the inclined surface than its upper end, is located on the outside.

Here, the lower end of the outlet 4 refers to the upper end of the wall of the inclined surface 2 that connects to the bottom of the peripheral wall forming the outlet, and the upper end of the outlet refers to the upper end of the wall of the inclined surface 2 that connects to the upper end of the inclined surface 2. The bottom end of the wall is called respectively.

In addition, in order to effectively use the space inside the container to load powder and to completely prevent it from flowing out from the outlet during transfer, the lower end of the outlet must correspond to the angle at which the powder flows out. It is particularly preferable to provide the outlet so as to be located outside of the position where the outlet is located.

Here, the outflow angle of the powder and granular material is, for example, when the powder and granular material is loaded into the container up to the loading port in Fig. 1, the slope of the powder and granular material flowing out from the discharge port is defined by the perpendicular line drawn from the top end of the discharge port. This is angle B measured as a reference.

The position corresponding to the outflow angle is the position C where the line of angle B is placed on the inclined surface connecting to the bottom surface.

The above-mentioned angle B varies depending on the fluidity of the granular material to be handled, the position of the discharge port, the shape of the box-like body, etc.

A hanging device 6 is provided around the sheath-like body, and is used to connect a rope-like object such as a rope, wire, or chain to lift and tilt the container.

The above operations can be carried out stably if the suspenders are provided at three locations around the sheath-like body, but it is preferable to provide the hangers at four joints around the sheath-like body as shown in the figure, since the above operations can be carried out more stably. .

In any case, the hanging tools are arranged so that at least three hanging tools are placed around the box-like object, and the projection point created by projecting the center of gravity of the box-like object onto the bottom surface of the box-like object is the point where the hanging tools are located. By arranging the convex polygon formed by connecting the polygons to be located within the projected polygon formed by projecting onto the bottom surface of the box-like object, the box-like object can be hung stably.

In addition, if the discharge port is provided along the entire length of the container, in order to prevent abrasion of the rope-like material due to powder flowing out from the discharge port, the hanging device should be provided on the side surface adjacent to the side surface of the container where the discharge port is located. is preferred.

It is easier to rotate the container if the hanger is located below the outlet.

The shape of the hanging device is not particularly limited, such as a hook shape, a semicircular shape, a chain shape, etc., and is appropriately determined according to the shape of the tip of the rope-like object.

FIG. 2 is a perspective view showing the state when the powder and granular material in the container of FIG. 1 is being discharged.

For example, a container transported on the bed of a truck is transported above the destination by connecting rope-like objects 19, 19, and 2 to a hanging device.

There, the ropes 1 and 3 are fixed or loosened, while the ropes 1 and 2 are wound or fixed.

Of course, the operations of loosening the rope-like objects A and C and winding the rope-like objects A and C may be performed at the same time.

Through the above operation, the powder and granular material 7 in the container is smoothly discharged from the discharge port 4 by only rotating the container by approximately one-fourth of a turn.

FIG. 3 shows an embodiment in which the container of the present invention is provided with a sudden roll prevention device 8.

When a container is tilted to a certain angle, the container may suddenly roll over due to movement of the powder inside.

This phenomenon occurs particularly frequently when the hanging device is located below the center of gravity of the container.

According to this aspect, the container can be stably tilted by providing the sudden roll prevention device 8 above the hanging device located on the discharge port side and connecting the rope-like object to the hanging device by passing a rope-like object through this device.

The sudden roll prevention device is not particularly limited as long as it has a structure that allows the rope-like object to pass through freely and allows the rope-like object to be attached and detached, and may be in the shape of a key.

A shape such as a semicircular shape or a nine-circular shape is preferably adopted.

By providing the sudden roll prevention device 8, sudden roll of the container can be controlled by the tension of the rope-like material, as shown in FIG.

Although FIGS. 1 and 3 show an embodiment of the container provided with one outlet, the outlet may also be provided on two opposing sides as shown in FIG. 5.

It is also a preferable embodiment to provide a lid 11 that can be freely opened and closed on the outside in order to prevent dust from flying from the discharge port when the container is transferred.

As mentioned above, the container is lifted by connecting a rope-like object to a lifting device.

In the container hoisting work, the work can be carried out efficiently by fixing the rope-like object with the fixing tools 9 having a length matching the interval between the container hoisting tools.

In this case, the fixture 9 may be attached directly to the hanging rope-like object, as shown in FIG.

However, by attaching strings of appropriate length to both ends of the fixture 9,
It is more convenient to attach it to a hanging rope-like object through the string, since this does not impede the vertical movement of the rope-like object when rotating the container during discharge.

Moreover, instead of the sudden roll prevention device shown in FIG. 3, a sudden roll prevention device 10 shown in FIG. It can also prevent containers from tipping over.

The condition of the container of this invention varies depending on the type and amount of powder and granules handled, but it can be used for wood, plastic, etc.

Iron, stainless steel, etc. are commonly used.

Since the container of the present invention has a discharge port on the side, the powder inside can be easily discharged by lifting it with a crane or the like and turning it about a quarter turn.

Therefore, it is possible to increase the size of the device, and it is possible to efficiently transfer a large amount of powder and granular material.

The container of the present invention is suitable for transporting earth and sand, cement tarinker, wheat salt, and other granular materials.
