DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bucket for a bucket elevator, and more particularly to a bucket which can be easily fixed to an endless chain or an endless belt.

[0002]

2. Description of the Related Art A number of buckets are attached at regular intervals to an endless chain or belt (hereinafter referred to as an endless chain), and are circulated at a low speed to discharge a transported object picked up by a bucket at a lower position at an upper position. Bucket elevators that perform a continuous operation, whereby the goods are continuously transferred from a lower position to an upper position, are already well known.

[0003] Generally, since the cargo is discharged at the upper turning portion of the endless chain mounted vertically, the effective discharge of the cargo at that position is taken into consideration. In a bucket elevator of the type, as shown in FIG. 6, the bucket 30 has bolts and nuts 33 near the bottom of the back plate portion 31.
Is attached to the endless chain 32.

[0004]

However, when each bucket is attached to the endless chain with bolts and nuts near the bottom of the back plate portion as described above, the bucket has a substantially inverted triangular side surface and a housing portion. Is difficult to attach to an endless chain because it narrows toward the bottom, and it takes a lot of time and effort to securely attach a large number of buckets to the endless chain. It was strongly requested.

The present invention has been made in response to the above-mentioned demands, and has as its object to provide a bucket of a bucket elevator that can be easily attached to an endless chain.

[0006]

According to the present invention, a hole through which a tip of a fastening tool for attaching the bucket body to an endless chain can be inserted is penetrated through a front plate portion of the bucket body. The above problem has been solved by closing the through hole in the front plate after attaching the bucket body.

That is, the bucket of the bucket elevator according to the present invention is formed in a substantially inverted triangular shape as viewed from the side by a back plate portion, left and right side plate portions and a front plate portion, and the back plate portion is attached to an endless chain. In the bucket body having a hole penetrated, a hole through which a tip portion of a tightening and fixing tool used for fixing the bucket body to the endless chain with bolts and nuts is inserted through the front plate portion. The hole is closed after the bucket body is fixed to the endless chain.

[0008]

The front plate of the bucket body has a hole through which the tip of a fastening tool used for fixing the bucket body to the endless chain can be inserted.
The work of attaching the bucket body to the endless chain has been significantly simplified. That is, by inserting the tip of the tightening and fixing tool from the hole and attaching and fixing the bucket body to the endless chain, and then closing a through hole in the front plate portion of the bucket body, a number of buckets are connected to the endless chain. Can be equipped efficiently in a short time.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENT A back plate portion 3 having a mounting hole 2 to an endless chain 7, a left and right side plate portions 4, 4 and a front plate portion 5 are integrally formed in a substantially inverted triangular shape when viewed from the side. In the main body 1, the present invention is directed to a hole through which a tip portion of a socket wrench used as a tightening and fixing tool 9 used for fixing the bucket main body 1 to the front plate portion 5 to the endless chain 7 with bolts and nuts 8 can be inserted. 6 is penetrated.

The nut is tightened by a tightening and fixing tool 9 inserted into the through hole 6 in the front plate portion 5 to fix the bucket body 1 to the endless chain 7.

After fixing the bucket body 1 to the endless chain 7, the hole 6 penetrating through the front plate portion 5 of the bucket body 1 has a tip of the body 11 slightly larger than the inner diameter of the hole 6, as shown in FIG. It was formed in a tapered part 12 having an outer diameter, and was closed by a plug-shaped hole closing body 10 in which a split groove 13 was formed in the tapered part 12. Reference numeral 14 denotes flanges provided on both sides of the surface of the front plate portion 5.

In the above embodiment, the hole 6 is formed by a plug-like hole closing body 10.
5 shows a closed state, but as shown in FIG.
May be closed with a hole closing body 10 composed of a bolt and a nut.

[0013]

As described above, the bucket of the bucket elevator according to the present invention is used for fastening and fixing the bucket body 1 to the end plate 7 with the bolts and nuts 8 on the front plate portion 5 of the bucket body 1. Since the hole 6 into which the tip portion of the tool 9 can be inserted is provided, the fixing of the bucket body of the endless chain can be easily and easily performed by the fastening tool 9 inserted using the hole 6. Can be. Then, after attaching and fixing the bucket body 1 to the endless chain 7, the hole 6 may be closed. Therefore, an excellent effect is achieved that a large number of buckets can be efficiently mounted on the endless chain in a short time.
