SU937285A1 - Device for overturning conveyer buckets - Google Patents

Description

The invention relates to transporting machines, namely, an CTBciM device for tilting conveyor buckets, which are used to transport pulverized, granular and lumpy bulk cargo at chemical and coal felting plants, at fuel supply stations of power plants, coke gas, cement and other plants.

 Devices for tilting conveyor buckets are known, including guiding lamellar roller chains on the axles of which buckets are hinged, and mounted on a hinged reinforcement, supported on eccentrics, bucket discharge devices in the form of stops, and bucket return device 1.

The disadvantage of this device is a significant abrasion of the bucket surface, which interacts with the unloading device and the bucket return device by making the latter in the form of a curved tire surface that constantly interacts with the bucket.

The purpose of the invention is to increase the reliability of work by reducing the degree of wear of the buckets.

This goal is achieved by the fact that the unloading device of the bucket is equipped with rollers mounted on the frame behind the stops, and the bucket return device is made in the form

10 spring-loaded levers hinged on the frame.

FIG. 1 shows the proposed device, a general view; in fig. 2 the same, side view.

The device consists of a shaft 1, which is driven in rotation by an electric motor (not shown). On the shaft 1, the eccentric 2 is fixedly attached to the roller 3, on which the hinged frame 4 is supported. Along the guide tracks 5, buckets 7 are moved by means of the roller chains 6, which are suspended on the axes of the roller chains 6. On the frame 4, they are 25. the tilting supports 8 and the rollers 9, which constitute the discharge device of the buckets 7, are fastened.

Claims (1)

To smoothly return the bucket 7 to its original position, a bucket return adjustment is used, consisting of hinged levers 10 and springs 11. The bucket tipping device operates as follows. To set the tilting device to the working position, an electric motor (not shown) is turned on, which drives the shaft 1, which starts the rotation, and the eccentric 2 with its highest point is set to the upper position, through the roller 3 lifts the frame 4 to the working position. Along the Katkov chains 6, the buckets 7, which are suspended on the axes of the Katkov chains 6, move along guideways 5. The approach to the tilting support 8, the bucket 7 touches it with its lateral forming surface, starts rolling over it and gradually tilting, as a result the material is poured out of the bucket. When the bucket 7 rotates about 60-70 on the axle, it rests against the thrust roller 9, with the result that the bucket is finally tipped out and the material is poured out. Then, the bucket, returning to its original position, with its side walls touches the lever of the soothing device 10, moving further, squeezes the spring 11, on which the lever rests, and the bucket gradually descends to its original position. At the approach of the following buckets, the tipping is performed in the same way. As a result of using the proposed device, the capacity of the buckets increases to 30%, respectively, and the productivity of the bucket conveyor increases. Claims Device for tilting conveyor buckets, including plate-type roller chains, on the axes of which buckets are hingedly mounted and mounted on a hinged frame supported on eccentrics, an unloading device of buckets in the form of stops, and a device for returning buckets to their original position, characterized by that, in order to increase the reliability of work by reducing the degree of wear of the buckets, the unloading device of the buckets is equipped with reinforced frames on the frame beyond the stops, and The bucket return feature is made in the form of spring-loaded arms hinged on the frame.
