Abstract

This invention relates to industrial vehicles. The purpose of the invention is to increase production by reducing the return flow and ensuring a more complete cleaning of the elevator from the load at the end of its work.

He closes infinitely closed to the forehead with a horizontal loading section 7. At the same time, L 6 envelops the upper 8, middle 9 and lower 10, which is spring-loaded up to section 7, the drums. The side of the L 6 facing K 5 is ribbed. The pressure rollers (P) 11 are fastened to the housing 1 on the inner side of the ascending branch L 6.

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

The purpose of the invention is to increase productivity by reducing the reverse rash and providing a more complete cleaning of the elevator from the load at the end of its work.

Figure 1 shows the Elevator, a General view; figure 2 - bucket, General view; in FIG. 3, view A in FIG. 1, with the elevator loaded; figure 4 - the same, at the end of the elevator; on fig.Z - the tape is infinitely closed, general view.

In case 1, the upper 2 and lower 3 drums are installed, bending around a vertically closed traction body, for example, a tape 4 with buckets 5 consisting of the rear and two side walls arranged one relative to the other with mutual overlap (Fig. 2). To the buckets 5 on the ascending branch of the belt 4, the belt 6 is adjacent to the endlessly closed belt 6 with a horizontal loading section 7. The tape 6 is infinitely closed around the top 8, middle 9 and bottom 10, which is spring-loaded along the loading section 7, the drums. The pinch rollers 11 are fixed on the housing 1 on the inner side of the ascending leg of the infinitely closed tape 6 with the ability to interact with it. On the inner side of the belt 4, the supporting rollers 12 are fixed on the housing 1. The upper drum 8 and the pressure rollers 11 are spring-loaded so that they can be moved towards the buckets 5 on the rising branch of the belt 4. The width is infinitely closed

tape 6 and the length of the pressure rollers 11 is less than the distance between the side walls of the bucket 5. The side of the infinitely closed tape 6, facing the buckets 5, is made with corrugation (FIG. 3). Along the horizontal - cuff section 7 on the housing 1, lateral guides 13 are mounted.

Bucket Elevator works as follows.

The bulk cargo entering the horizontal section 7 of the infinitely closed tape 6 is fed into the internal space in a continuous flow. Due to frictional forces, the material is entrained in buckets 3, pressing an infinitely closed tape 6 from the inner wall of the buckets 5. Depending on the amount of material supplied to the horizontal loading section 7, the infinitely closed tape 6 can occupy different positions with respect to the side walls of the buckets 3 (Fig. and 4).

The pinch rollers 1 I ensure that the endless closed tape 6 is constantly pressed against the load during operation. Holding the load on the horizontal loading section 7 during transport is provided by side guides 13. When loading of the loading on the horizontal loading section 7 stops, the pressing rollers 11 press the infinitely closed tape 6 to the rear wall of the bucket 3, while the remaining load in the upset branch of the upright branch removed.

Claims (2)

Claim 1. Bucket elevator, comprising a housing, a vertically closed traction unit with buckets attached to it, consisting of a rear and two side walls located relative to each other with mutual overlap, an infinitely closed tape with a horizontal loading section adjacent to the buckets on the 15th ascending branch vertically closed traction body and the upper, middle and lower envelopes, spring-loaded along the loading section, drums, and pinch rollers sealed on the housing from the inside of the ascending wind and an infinitely closed tape with the possibility of interacting with it, characterized in that, in order to increase productivity by reducing the back rash and providing a more complete cleaning of the elevator from the load at the end of its operation, the upper drum and pinch rollers are spring loaded with the possibility of moving into toward the buckets, while the width of the infinitely closed tape and the length of the pinch rollers are made smaller than the distance between the side walls of the buckets. 2. The bucket elevator according to claim 1, characterized in that the side of the infinitely closed tape facing the buckets is grooved. Type A Fi g ji
