This invention relates to industrial transport, in particular to a bucket elevator.

The purpose of the invention is to increase the versatility and reliability.

FIG. 1 shows an elevator, general view; in fig. 2 — node I in FIG. one; in fig. 3 shows section A-A in FIG. 1 (rasUpory 10 interacting with the bosses of the previous 5. as the bucket 4 moves, can also be made detachable relative to the bosses 5 and the stops 11 and with the possibility of adjustable angular rotation on the bearing fingers 6 and fixing them relative to the bosses 5. At the same time

the position of the support blocks); figure 4th surface of the lugs 10, adjoining with one adjustable stop; in fig. 5 — node II in FIG. 4, the cut; in fig. 6 - bucket with two adjustable stops; in fig. 7 shows the node III in FIG. 6, incision; in fig. 8 is a diagram of the position of the stops when changing the diameter of the support blocks; in fig. 9 is a diagram of changing the angular position of the bucket.

The bucket elevator contains drive 1 and tension 2 blocks, covered by two branches of round link chains 3, buckets 4 with their fastening elements to chains in the form of bob 5, rigidly connected to the side walls of buckets, and the fingers 6 placed in the holes of the bosses 5 and articulated with round link links, and deflecting blocks 7. On the axis 8 of the tension blocks 2, support blocks 9 are installed, which are made in the form of annular bandages and fixed directly on the tension block 2 by any known method . Each bucket 4 is equipped with two pairs of lugs 10 and 11 directed in opposite directions and displaced one relative to the other along the axis of the bearing pins 6, while the lugs 10 are designed to interact with the bosses 5 of the previous bucket 4, while the lugs 11 with the ability to interact with the support blocks 9.

The stops 10, which interact with the bosses 5 of the previous bucket 4, are rigidly connected to the bobs 5 of the bucket 4, and the stops 11, which interact with the support blocks 9, are made separately from the bobs 5 and with the possibility of adjustable angular rotation on the bearing pins 6 and fixation relative to the bobs 5 The means for fixing the stops 11 relative to bobster 5 is made in the form of cams 12 on adjacent end surfaces of the stops 11 and bobster 5 and nuts 13 screwed on the ends of the bearing fingers.

The end faces of the bobshch 5 and the stops 11 are also provided with locking means in the form of cams 12.

Bulk material is fed to the elevator through the loading chute 14 and discharged through the discharge chute 15.

The elevator works as follows.

The buckets 4 of the elevator are loaded in its lower part when they are rotated together with the tension blocks 2 and the transported load is supplied against the motion of the buckets 4 through the loading tray 14, and unloading in the upper part of the elevator to the dump tray 15 when the buckets 4 rotate together with drive blocks 1.

In the process of loading the buckets 4, the force of resisting the scooping of the load is overcome by the traction chains 3 through the bearing fingers 6, while the torque from the resistance to scooping relative to the bearing fingers 6, directed counterclockwise, is perceived directly by the supporting blocks 9 through the stops 11, and between the stops 10 and the lugs 5 of the previous bucket provides the minimum required clearance S.

After the bucket 4 leaves the loading zone and stops the contact of its stops 11 with the supporting blocks 9, the buckets 4 with the load are rotated counterclockwise under the action of the force of their gravity until the contact of the stops 10 with the bosses 5 of the previous bucket 4. In this position the buckets are transported 4 with a load.

When changing the diameter of the support blocks or the wear of the contact points of the stops 11 with the support blocks, the guaranteed contact of the said stops 11 with the support blocks 9 is achieved by unlocking the stops 11 with respect to the bosses 5 or with respect to the stops 10 and respectively with the bosses 5

11 around the bearing pins 6, while the position of the upper lugs 10 remains unchanged and the minimum necessary clearance S between them and the lugs 5 of the previous bucket 4 remains

If it is necessary to change the angular position of the bucket 4 relative to the bearing pins 6, the stops 10 and 11 are released relative to the bosses 5 and the bucket with the pods is rotated in the required direction around the bearing fingers, while the positions of the stops 10 and 11 are respectively relative to the previous bucket blocks 9 remains unchanged.

In the proposed elevator, the adjustable angular position of the stops interacting with the supporting blocks allows to ensure guaranteed contact of said stops with the blocks when changing the diameter of the latter, as well as when the stops are in contact with the supporting blocks i and

The adjustable angular position of the upper stops that interact with the front buckets of the pre-buckets allows for the minimum necessary clearance between them during operation .1

This, in combination with a similarly adjustable position of the lower stops interacting with the supporting blocks, allows the angular position of the buckets relative to the axes of the bearing pins to be changed and thus provide the most favorable conditions for scooping the transported bulk cargo depending on its properties.
