BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bucket of a bucket elevator for transporting sticky material.

[0002]

2. Description of the Related Art For example, asphalt pavement waste material excavated by road construction or the like has a sticky asphalt component adhered thereto. Often occurs. Therefore, such a waste material having adhesiveness is not generally transported by a bucket elevator. However, in recent plants, the height of the floor is increasing, and a bucket elevator having a structure capable of transporting the sticky waste material may be required.

In adopting a bucket elevator for transporting the sticky waste material, it is necessary to completely discharge the sticky waste material from the bucket and prevent the sticky growth. As one method, as disclosed in Japanese Utility Model Laid-Open Publication No. Sho 58-7718, the bottom of the bucket is constituted by a flexible elastic plate, and if the elastic plate is bent when the bucket is inverted, it is considered that the bucket is easily discharged. Can be

[0004]

However, it is conceivable that the sticky waste material adhering to the bucket cannot be completely discharged by simply flexing the weight of the elastic plate at the time of reversing the bucket.

SUMMARY OF THE INVENTION In view of the above points, the present invention has been made by further improving the structure of the above-mentioned bucket, and an object of the present invention is to provide a bucket of a bucket elevator capable of discharging an adhesive material without remaining as much as possible in the bucket. .

[0006]

According to the present invention, in order to achieve the above object, a flexible elastic plate is attached to each bucket of a bucket elevator along the inner surface of the bucket, and the bucket and the elastic plate are connected to each other. A weight having a weight that causes the bottom of the elastic plate to impact-deform when the bucket is turned over is housed in the space between the buckets.

[0007]

According to the bucket of the present invention, when the bucket having scooped up the material reaches the uppermost portion and starts to be inverted, the material is discharged from the bucket. At this time, the weight stored between the bucket and the elastic plate is reduced. Due to the centrifugal force and the gravity caused by the running of the bucket, the bucket falls on the bottom rear surface of the elastic plate and gives an impact, and the bottom of the elastic body is expanded and deformed toward the material discharge side. In this way, the impact of the weight of the weight on the bottom surface of the elastic plate and the deformation thereof cause the sticky material adhering to the elastic plate to be peeled off, and the material is discharged without remaining in the bucket.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

In the bucket elevator 1, an endless chain 5 is wound between an upper chain wheel 3 and a lower chain wheel 4 disposed in a casing 2, and a number of buckets 6 are mounted on the chain 5 at predetermined intervals. A material inlet 7 is provided at the lower part of the casing, and a material discharge chute 8 is provided at the upper part of the casing.

As shown in FIG. 2, a flexible elastic plate 9 such as a rubber plate is provided on the bucket 6 along the inner surface of the bucket, and both ends thereof are attached by fasteners 10 such as bolts and nuts. The bottom of the elastic plate 9 is freely deformed.

A weight 11 such as a steel ball is accommodated in a space between the bucket 6 and the elastic plate 9. The weight 11 has an appropriate weight to shock-deform the bottom of the elastic plate 9 when the bucket is inverted. Are selected. The elastic plate 9 is made of a material having an appropriate elasticity or a plate thickness so that the weight 11 does not spill outside from between the bucket 6 and the elastic plate 9.

When the tacky material is scooped up by the bucket 6 and the bucket 6 reaches the top and starts to be inverted, the material is discharged from the bucket 6 and
Weight 11 stored in the space between bucket 6 and elastic plate 9
Is dropped on the bottom and back surface of the elastic plate 9 by the action of the centrifugal force and gravity caused by the running of the bucket 6 and gives an impact to swell and deform the bottom of the elastic body 9 toward the material discharge side.

As described above, the weight of the weight 11 makes the elastic plate 9
The adhesive material adhering to the elastic plate 9 can be peeled off by the impact and deformation on the bottom surface of the plate, and the material is discharged without remaining in the bucket.

Although the weight 11 is accommodated in the space between the bucket 6 and the elastic plate 9 in the above embodiment, the weight 11 is attached to the bottom surface of the elastic body 9 or formed integrally. You may do it.

[0015]

As described above, according to the present invention, a flexible elastic plate 9 is attached to the bucket 6 along the inner surface of the bucket, and the bucket 6 and the elastic plate 9 are turned over when the bucket is turned over. The weight 11 having a weight that causes the bottom of the elastic plate 9 to be shock-deformed is housed. When the bucket is turned over, the weight 11 falls on the elastic plate 9 by the action of the centrifugal force and the gravity caused by the running of the bucket 6 to give an impact and elasticity. Since the bottom of the body 9 is deformed, the sticky material attached to the elastic plate 9 can be peeled off, and the sticky material can be discharged without remaining in the bucket as much as possible.
