Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a uniform loading device used when loading crushed dust or metal into an open container.

[0002]

2. Description of the Related Art When loading so-called loose materials such as crushed dust and metal into an open container, the conventional swivel conveyor is used in order to increase the volumetric efficiency of the container by loading it into the container as uniformly as possible. The device is used.

In this case, the swivel conveyor device is one in which a chute is provided at the tip of the belt conveyor and the base of the belt conveyor is rotatably attached. The chute is rocked on an open container.

[0004]

However, the swivel conveyor device as described above has a problem that a space is required for swiveling and swinging in addition to its own installation space.

Therefore, it is an object of the present invention to provide a uniform loading device which does not cause a problem of installation space.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention is a uniform loading device installed between a head chute of a loading conveyor and an open container, facing the head chute. A hopper having an upper end opening and a plurality of lower end openings facing the open container is provided, a damper having a variable inclination angle is provided inside the hopper, and the lower end of the damper is changed by changing the inclination angle of the damper. The configuration is such that the lower end openings are exposed.

A driving device for reciprocating the hopper in the horizontal direction may be provided in the hopper.

[0008]

When the objects to be transported are loaded into the open container by using the above-mentioned uniform loading device, the inclination angle of the damper is appropriately changed, and the position of the lower end opening of the hopper facing the lower end is sequentially switched, whereby the inside of the container is changed. The heights of the objects to be loaded are made uniform.

When the hopper is reciprocally moved in the horizontal direction by the driving device, the loading height can be made more uniform.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A uniform loading device 1 shown in the accompanying drawings is installed between a distribution conveyor 2 and an open container 3.
The distribution conveyor 2 is a head chute 5 of the loading conveyor 4.
Is provided at the lower end of.

The uniform loading device 1 has a fixed frame 6
A moving frame 9 for distribution, which is supported via rollers 8 on two parallel rails 7 (see FIG. 3) in the width direction of the loading conveyor 4, and a hopper 11 provided inside the frame 9. It consists of and.

As shown in FIG. 2, the moving frame 9 is driven by transmitting the driving force of a motor 12 installed on the frame 9 to the roller 8.

The hopper 11 is attached to a support frame 10, and the roller 1 attached to the support frame 10.
3 is supported on the moving frame 9 by two parallel rails 14 provided in a direction orthogonal to the rail 7.

The support frame 10 and the hopper 11 integrated with the support frame 10 support the piston rod 15 ′ of the air cylinder 15 attached to the moving frame 9 on the support frame 10.
By reciprocally connecting to the rail 14, the rail 14 of the moving frame 9 is reciprocated. The upper end opening 16 of the hopper 11 is
As shown in FIG. 3, it is a quadrangle, and the central passage 1 is located below it.
7 (see FIG. 1), a front passage 18 and a rear passage 19 are arranged in parallel, and lower end openings 21, 21, 21 are provided at the lower ends of the passages 17, 18, 19, respectively.

Inside the hopper 11, a damper 23 is rotatably supported by a shaft 22 above the central passage 17, and an air cylinder 24 for driving the damper 23 is provided on the outer surface of the hopper 11. Is installed,
A piston rod of an air cylinder 24 is rotatably connected to an arm 25 integrally provided on the outer end of the shaft 22.

An open container 3 is installed below the hopper 11. In this embodiment, three open containers 3 are installed in parallel as shown in FIG. 2, and the same uniform loading device 1 is installed for each open container 3. Further, a common distribution conveyor 2 is provided above each uniform loading device 1.

The distribution conveyor 2 is movably supported by mounting rollers 29 attached to the conveyor frame 28 on rails 31 on the fixed frame 6. A chute 33 is provided at each end of the conveyor frame 28.
34 is provided, and both ends of the belt conveyor 35 are exposed inside the chutes 33, 34. The belt conveyor 35 is driven by a motor 36 installed on a chute 33, and the roller 29 is driven by a motor 32 installed on a chute 34.

The head chute 5 of the loading conveyor 4 faces above the belt conveyor 35.

The apparatus of the embodiment is as described above,
Next, the operation will be described.

Now, in FIG. 2, crushed waste is loaded in the open container 3 at the left end, the distribution conveyor 2 is moved to the leftmost end as shown, and the chute 33 at the left end is moved to the hopper of the uniform loading device 1 at the left end. Show on 11. When crushed waste is conveyed by the loading conveyor 4 in this state,
The crushed dust drops from the head chute 5 onto the belt conveyor 35 of the distribution conveyor 2, and is further thrown into the hopper 11 of the uniform loading device 1 from the chute 33 at the left end thereof.

When the lower end of the damper 23 in the hopper 11 is at an inclination angle facing the rear passage 19 as shown in FIG. 1, the crushed dust 37 introduced drops into the open container 3 through the rear lower end opening 21. In this way, if there is a pile of crushed dust 37 at the front of the open container 3,
Next, the air cylinder 24 is driven to switch the damper 23 to the vertical posture. Then, a pile of crushed refuse 37 is formed in the central portion of the open container 3 this time. Similarly, a pile of crushed refuse 37 is also created in the front part of the open container 3. When the required amount of the crushed dust 37 is loaded in this manner, the crushed dust 37 can be loaded almost uniformly without being biased to one place.

During the loading, the air cylinder 15
When the hopper 11 is driven to reciprocate back and forth,
Since the tops of the mountains of the crushed refuse 37 are relatively flat, the uniformity of loading is further promoted (see the alternate long and short dash line in FIG. 1).

When the loading into the open container 3 at the left end is completed as described above, the motor 3 of the distribution conveyor 2
2 is driven to move it, and the chute 33 at the left end is brought to face the hopper 11 of the uniform loading device 1 at the center, as shown by the alternate long and short dash line in FIG. Thereafter, in the same manner as the above-mentioned case, loading is performed on the central open container 3.

Further, when loading into the open container 3 at the right end, the chute 34 at the right end of the distribution conveyor 2 is made to face the hopper 11 of the uniform loading device 1 at the right end, and the driving direction of the belt conveyor 35 is set to each of the above-mentioned respective directions. Reverse the case and load in the open container 3 at the right end.

The installation location of the open container 3 is 1
In the case of a location, only one uniform loading device 1 is required, and the distribution conveyor 2 is not necessary, and the head chute 5 of the loading conveyor 4 is directly faced on the hopper 11, and the same procedure as described above is performed. Carry out loading.

[0026]

As described above, the uniform loading device of the present invention is provided with the damper capable of changing the inclination angle so as to face the plurality of lower end openings provided in the hopper, so that the loading height into the open container is increased. Can be made uniform, and the volume efficiency of the open container can be improved. Moreover, since the floor area of the uniform loading device does not particularly increase due to its installation, it is advantageous in terms of installation space.
