Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a skip hoist, and more particularly to a skip hoist in which a bucket is pulled up above an upper opening of a hopper while being guided by a guide rail.

In this type of conventional device, as shown in FIG. 1, two guide rails 12A extend from the bottom side of the hopper 10 along the side surface thereof, and the tips thereof are bent upwardly from the upper opening 10A of the hopper 10. ,12B
are provided, and guide rails 12A, 12B
The legs gradually open as they approach the upper part of the opening 10A.

A wire rope (not shown) is attached to the bucket 14, which is open at the top, and a winding device (not shown) winds up the wire rope, so that the bucket 14 is guided by the guide rails 12A, 12B under the hopper 10. It is pulled up from the side above the upper opening 10A, and at this position, the guide rails 12A and 12B are spread, so that the bucket 14 is tilted downward.

In this type of device, the bucket 14 is inverted above the upper opening 10A of the hopper 10 and tilted downward, and then when the wire rope is loosened, the bucket 14 can be lowered.
In addition, when the bucket 14 is in an inverted state, the angle of repose α of the bucket discharge surface 14A is generally about 60 degrees.

The conventional device shown in FIG. 1 is constructed as described above, so that, for example, the bucket 14 in which the scum is accumulated is guided by the guide rails 12A, 12B by the winding device from the lower side of the hopper 10 to above the upper opening 10A thereof. When transported to the hopper 10, it is reversed and tilted downward, and the residue in the bucket 14 is discharged into the hopper 10 from the opening 10A. Thereafter, when the winding device is reversed and the wire rope is loosened, the empty bucket 14 descends under its own weight to the lower side of the hopper 10, and the residue is accumulated there again. In this way, the residue and the like are transported into the hopper 10 in the bucket 14.

However, the conventional device described above has a bucket 14
When the hopper is turned upside down on the hopper 10 and waste material is discharged, the inclination angle of the bucket discharge surface 14A cannot be greater than the rest angle.
Release residue such as rice residue is generated, which causes hopper 10
There was a problem that the amount of transportation to the plant decreased.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide a skip hoist that can efficiently transport materials to a hopper.

In order to achieve the above object, the present invention provides a skip hoist having an open top bucket that is pulled up while being guided by a guide rail and slopes downwardly above the upper opening of the hopper. A cross section that extends inside the bucket along the bottom surface and the bottom surface of the bucket that is tilted upward, and is rotatably attached to the open end of the bucket that becomes the lowest end when the bucket is tilted. A movable discharge plate having a substantially L-shape, and a movable bottom plate disposed between the movable discharge plate and the bottom of the bucket and rotatably attached to the bottom of the bucket, which becomes the top when the bucket is tilted. This is a skip hoist that is characterized by:

Hereinafter, preferred embodiments of the skip hoist according to the present invention will be described based on the drawings.

In FIG. 2, openings 10A and 10B are provided on the upper and lower sides of the hopper 10, and here, the residue in the bucket 14 is discharged into the hopper 10 from the opening 10A, and the residue in the hopper 10 is discharged from the opening 10A. is discharged from the opening 10B.

Guide rails 12A and 12B are provided that extend from below the hopper 10 along its side surfaces, and their tips are bent upwards of the opening 10A and gradually open. The tips of the guide rails 12A and 12B are connected to the mount 1.
It is fixed to the side of 6.

Winding devices 20 and 22 are installed on the pedestal 16, and the winding devices 20 and 22 rotate in the normal direction to wind up the wire rope 24 and roll it up into the bucket.
4 can be pulled up, and by reversing the wire rope 24, the bucket 14 can be lowered by its own weight.

Therefore, the bucket 14 has guide rails 12A,
It is possible to reciprocate between the lower part of the hopper 10 and the upper position of its upper opening 10A while being guided by the hopper 12B. Also, bucket 14 is hoppa 10
In the upper position of the upper opening 10A, the guide rails 12A and 12B are spread, so that the discharge surface 14A thereof can be tilted up to the angle of rest α.

Here, in the present invention, the upper opening 1 of the hopper 10
One end of a movable discharge plate 26 is rotatably attached to the inner surface of the bucket 14 on the lower side above 0A, that is, to the tip (opening side end) of the bucket discharge surface 14A. This movable discharge plate 26 has a cross section of approximately L.
It has a letter shape and extends along the bucket discharge surface 14A and the bucket bottom surface 14B. Furthermore, a movable bottom plate 28 is arranged between the movable discharge plate 26 and the bucket bottom surface 14B. This movable bottom plate 28
is, when Bucket 14 is reversed, Bucket 1
It is rotatably attached to the bucket bottom 14B which is the top of the bucket.

A preferred embodiment of the present invention has the above configuration,
The effect will be explained below.

Dregs are accumulated in a bucket 10 below the hopper 10, and the hopper 10 is pulled up by winding devices 20 and 22 and reaches above the upper opening 10A while being guided by guide rails 12A and 12B. At this time, the guide rails 12A, 1
2B gradually opens its legs, so the bucket 10 gradually tilts downward and reverses to the angle of repose α. As a result, the upper part of the residue inside the bucket 14 is removed from the hopper 1.
begins to be released into 0. Since the bucket 10 is tilted downward, the movable bottom plate 28 rotates counterclockwise in FIG. 2 under its own weight and presses the bottom plate portion of the movable discharge plate 26. As a result, the movable discharge plate 26 rotates clockwise in FIG.
The amount of reversal is greater than that of No. 4, and all of the residue in the bucket 14 is discharged. In particular, in this embodiment, the rotation center of the movable discharge plate 26 and the movable discharge plate 2
Since the distance between the end of the movable discharge plate 26 that restricts the rotation of the movable discharge plate 26 is small, the movable discharge plate 26 can be moved without increasing the gap between the movable discharge plate 26 and the bucket 14
The amount of rotation of 6 can be increased, and bucket 1
The integrated capacity of No. 4 does not decrease significantly either.

When the discharge of the residue is finished, the winding devices 20, 2
2 is reversed, the wire rope 24 is loosened, and the bucket 14 descends under its own weight toward the bottom of the hopper 10. At this time, the guide rails 12A and 12B are gradually closing, so the opening of the bucket 10 faces upward. At this time, as the bucket 14 returns, the movable bottom plate 28 first rotates clockwise relative to the bucket 14. , after which the movable discharge plate 26 begins to move. For this reason, a gap is created between the movable bottom plate 28 and the bottom plate portion of the movable discharge plate 26, and objects to be transported, such as scum, that are caught between them fall and slide down the bucket discharge surface 14A. Then, when the opening of the bucket 14 faces upward, the movable discharge plate 26 and the movable bottom plate 28 rotate under their own weight and return to their original states.
That is, the movable bottom plate 28 is in contact with the bucket bottom surface 14B, and the movable discharge plate 26 is in contact with the top of the movable bottom plate 28 and the bucket discharge surface 14A.

Thereafter, the scum is accumulated in the bucket 14 again, and its transport into the hopper 10 is repeated.

As explained above, according to the present invention, a rotatable movable discharge plate and a movable bottom plate having an L-shaped cross section are provided on the discharge surface and the bottom of the bucket, and when the bucket is reversed on the hopper, the weight of these is Since it rotates at transportation can be carried out efficiently.

In addition, according to the present invention, even if the ceiling above the hopper is low and the bucket cannot be turned over to the angle of repose, the movable discharge plate and the movable bottom plate can be rotated by their own weight, so that the residue inside the bucket can be removed. Therefore, the device according to the present invention can be installed even in buildings with low ceilings, which was previously impossible.
