Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bulk shipping device for loading powder and granular materials such as grain flour, wheat flour, cement, and mixed feed from a storage hopper onto a transport vehicle or the like.

Generally, equipment for loading this type of powder onto the platform of a transport vehicle such as a truck is constructed by locating a powder storage hopper at a height above the ground and facing the discharge port at its lower end. Usually, a truck or the like is introduced into the container and the powder is dropped through a chute or the like.

As for the loading operation, since the falling powder and granules are piled up in a mountain shape according to a predetermined angle of repose, for example, as shown in Fig. 1, a truck 1 with a large loading platform 2 is
They are moved back and forth several times with respect to the storage hopper 3, stacked in several piles, and after smoothing the surface, they are covered with sheets.

However, in reality, such work is often subject to various restrictions due to interference with surrounding buildings and the like. In other words, it is sufficient that there is ample work space below the storage hopper in relation to the storage hopper and the approach position of the truck, but generally attached equipment, other equipment, buildings, etc. are nearby. Usually, the working space is provided with only a narrow margin for trucks, etc. to enter, and therefore it is difficult to make small forward and reverse movements of trucks in such places. If this is done during the loading of the granules, there is a problem in that accidental contact with peripheral equipment is likely to occur. In addition, since there is a limit to how far a vehicle can enter with a long loading platform, workers may have to spend a considerable amount of time leveling powder and granules piled up in a part of the loading platform over the entire loading platform. .

These problems are difficult to solve based on the concept of moving trucks, etc., with respect to a fixed storage hopper. The present invention was developed with the aim of solving the above-mentioned conventional difficulties by making the position freely movable.

The above object is effectively achieved by changing the position at which the granular material is dropped onto the truck bed or the like, without directly relating to the position of the storage hopper itself.

The gist of the present invention to achieve such an object is to carry out bulk shipping in which powder and granules are dropped and loaded onto the loading platform of a transport vehicle located below through the lower end discharge port of a powder and granule storage hopper. The apparatus includes a conveyor support stand located near the lower end of the discharge port at the lower end of the hopper, and a conveyor apparatus for conveying falling powder and granular material supported on the support stand and extending in the horizontal direction;
The conveyor device includes a horizontal rail disposed at a position horizontally offset from the lower end discharge port of the hopper, and a pedestal that can run along the horizontal rail, and the conveyor device has a downstream end in the conveying direction connected to the pedestal. They are pivotally connected, and are rotatable in a horizontal plane on the conveyor support base and extend/extend.
There is provided a bulk shipping device for powder and granular materials, characterized in that it is provided so as to be movable backwards.

It goes without saying that a known chute for guiding powder and granular material falling may be provided so as to hang downward from the fluid being conveyed by the conveyor device.

Further, although the object of the present invention is usually fully achieved by installing the horizontal rails that guide the movement of the downstream end of the conveyor device in a straight line, this requires that they be linear in the strict sense. In addition to this, the entire horizontal rail may be provided so as to be movable in the horizontal direction perpendicular to this, and in this way, it becomes possible to move the falling position to any position within the horizontal plane.

The present invention will be described below based on embodiments shown in the drawings.

FIG. 2 shows an overall front view of the bulk shipping apparatus according to the present invention, and FIG. 3 shows a plan view.

Further, FIG. 4 is a plan view illustrating the conveyor support stand, FIG. 5 is a front view thereof, and FIG. 6 is a diagram showing the connection relationship between the conveyor device, the horizontal rail, and the pedestal.

In these figures, 4 indicates a hopper, and 5 indicates a powder discharge port at the lower end of the hopper, which can be opened and closed as appropriate by a discharge port opening/closing slide device 6 assembled on a conveyor support stand, which will be described later. The discharge port opening/closing slide device 6 includes a slider (not shown) that is opened and closed by a piston-cylinder device 7.

Reference numeral 8 denotes a conveyor support stand arranged below the discharge port of the hopper 4, and is constructed as follows.

That is, a beam assembly 9 constructed across the frame of a building (not shown) is positioned below the hopper, and a ring rail 10 forming a circle in a horizontal plane is fixed below the hopper 4.

A frame 11 is rotatably mounted on the current rail 10, and a rotatable connection is provided between the frame 11 and the beam assembly 9 by a vertical axis at the center of the ring rail 10.
(See Figures 4 and 5) 0 This frame corner 11 has pillars 13 extending upward from the four corners of the rectangle, and the above-mentioned opening/closing slide device 6 is attached to the upper part of the pillar 13. It supports a conveyor device, which will be described later, so that it can be inserted and moved through the sides of the rectangle.In order to smoothly move the conveyor device, rollers 14, which are rotatable along the insertion direction, are provided at the four corners of the rectangle. It is assembled.

In short, the conveyor support stand 8 has a structure that supports the conveyor device so that it can rotate freely in a horizontal plane around the position of the lower end of the hopper, and supports it so that it can move laterally in the horizontal plane.

Next, referring to the conveyor device 15, this has a casing 17 that houses a horizontally extending conveyor 16 inside and is open upward except for both ends. It has a structure in which it is inserted in the direction and movably supported by rollers 14.

Therefore, in this conveyor device 15, the upper surface of the conveyor 16 always faces the powder discharge port 5 at the lower end of the hopper, and the powder and granules dropped from the hopper are transported downstream by the conveyor.

A bellows-shaped chute 18 is installed at the downstream end of this conveyor device to guide the fall of the powder and granules downward, and as mentioned above, the conveyor device 15 is moved in a horizontal plane by the conveyor support 8. By being able to freely rotate and move forward and backward in the lateral direction, the falling position of the powder and granular material can be changed.

The casing 17 of the conveyor device 15 has a box-shaped head 17' at its downstream end, and its upper and end portions are closed.

Further, the bellows-shaped chute 18 has a wire 19.2.
0 and the lower end of the chute is connected via a pulley mechanism to a drum 22 rotated by a forward-reverse rotation type motor 21 on the conveyor casing 17, and the drooping length of the drum 22 can be adjusted during winding and unwinding by the drum 22. It looks like this.

Next, the mechanism for moving and rotating the conveyor device 15 will be explained. A pair of horizontal rails 23, 23 are horizontally installed at a position horizontally apart from the lower end position of the hopper and at approximately the same height. This horizontal rail 2
3.23 The pedestal 25, which is guided in a fixed direction by the rollers 24 and 24 that rotate the soil, is attached to a gear 27 which is pivoted on a rotatable vertical shaft 26 supported by the pedestal 25, and a long length is attached to the one horizontal rail 23. The vertical shaft 26 can be moved by meshing with a fixed rack 28 along the direction, and the vertical shaft 26 can be rotated by a forward/reverse rotation type motor 30 on the casing 17 via a bevel gear 29.29. ing.

The vertical shaft 26 is connected to the head 17' of the casing 17 of the conveyor device 15, so that the casing 17 and the frame 25 can pivot about the shaft 26.

Next, the operation and operating state of the above-mentioned device as a whole will be explained. First, from the state shown in FIGS. 2 and 3, operation means (not shown) (this may be a remote control means such as a cable-connected switch) When the operator starts motor 3
0, this causes the vertical shaft 26 to rotate, thus causing the gear 27 to move along the horizontal rail 23.23 while meshing with the rack 28. This movement is the movement of the frame 25, and the head 17' of the casing 17 is pulled out from the frame 11 while changing its angle accordingly. Then, when the chute 18 is made to hang downward and the discharge port opening/closing slider device at the bottom is opened, the powder and granules in the honopa 4 fall onto the rotating conveyor 16, and are carried downstream on this conveyor. It will be loaded downward from the chute 18.

If the mount 25 is moved appropriately by the motor 3o, the position of the chute 18 can be freely moved along the horizontal rail. For example, the loading platform of the truck can be positioned below the horizontal rail. This makes it possible to load the truck as shown in Figure 1 without moving it once it has been stopped, or even to load in a series of piles. Therefore, all you have to do is bring the truck, etc. into the loading position, and there is no need to move it forward or backward later, and the risk of interference with surrounding equipment is greatly reduced, as well as the work of leveling the loaded powder. This also has the effect of significantly reducing the amount of damage.

Figure 7 shows that the casing 17 of the conveyor device is rotated and pulled out from the powder discharge opening 5 at the lower end of the hopper to change its posture and change the falling position of the powder along the horizontal rail. To illustrate the situation, the line A-A in the figure shows the locus of movement of the gantry along the horizontal rail, and also shows the center position in the width direction of the loading platform of the truck or the like that has entered.

Note that the present invention is not limited to the above embodiments,
For example, if the target is flour, it is better to use a screw conveyor as the conveyor device.
Other modified embodiments that do not impede the present invention are included.

As described above, the apparatus for bulk shipping of powder and granular material according to the present invention solves the problems associated with the driving operation of the transport vehicle when loading powder particles, which were considered to be difficult in the past, and the work space is restricted. It effectively eliminates the accompanying problems and is extremely useful.
