Abstract

The invention relates to industrial transport and improves the quality of cleaning cargo in the form of grain. In the casing 6 with the boot shoe 7 and the discharge head 8 there is an infinitely closed traction body (TO) 1 with buckets (K) 2, each of which is made with perforations and a tray 9 located under the bottom K 2 and hinged on it in the place of its adjoining to TO 1. Tray 9 is spring-loaded relative to K 2 with the ability to interact with the stop 11 on K 2. Means for removing impurities from the cargo is made in the form of louver 12 with pipe 13 located parallel to the load-carrying branch TO 1 between it and the wall of the casing 6. When scooping grain K 2 trays 9 pulls away from the stop 11 and slides along the grain mound. Tray 9 returns to its original position, hitting the support 11 and thus cleaning the holes in K 2 from the waste fraction of the grain. which enters through the blinds 12 in the pipe 13. 2 Il.

Description

The invention relates to industrial transport, namely to bucket elevators.

The aim of the invention is to improve the quality of cargo clearance during operation of the elevator with grain.

Figure 1 shows the proposed elevator, General view; figure 2 - node I in figure 1.

The bucket elevator contains a flexible endlessly traction unit 1, on which buckets 2 with perforation 3 are fixed at equal intervals. The traction unit 1, the envelope of the drive drum 4 and the tension drum 5, is protected by a metal casing 6, to which the boot shoe 7 and the unloading head 8 are connected The bucket 2 is equipped with a tray 9, pivotally attached to its bottom at the seat of the bucket 2 to the traction body 1, a spring 10 and a stop

11. rigidly fixed in the bottom of the bucket 2 with the possibility of contacting with the tray 9. Between the buckets 2 and the metal casing 6 there is a built-in means for removing impurities from the load, made in the form of blinds 12 with a pipe 13 for outputting the passage fraction. To improve the separation conditions, the traction body 1 is equipped with a bypass roller 14, consisting of a shaft 15, two disks 16 and couplers 17. The bypass roller 14 is adjacent to the traction body Tc of the opposite side from the buckets 2. The boot shoe 7 is filled with a grain mound 18.

Bucket elevator works as follows.

The grain enters the boot shoe 7, is picked up by buckets 2, while the tray 9 is pulled from the stop 11 and slides along the grain embankment 18. After passing through the grain embankment 18 by the tray 9, the spring 10 returns it to its original position, hitting the tray 9 about the emphasis 11. thereby thereby cleaning the sieve surface 3 of the bucket 2. Using the outlet roller 14 in the form of a squirrel wheel, the traction body 1 comes into oscillatory motion, improving the conditions of grain separation in the buckets 2. The output fraction by buckets 2 is discharged through the discharge head 8, and the passage through the tray 9 through well lyuziynuyu septum displayed in pipe 13.

Claims (1)

Claim A bucket elevator, including a casing with a boot shoe and an unloading head, an infinitely closed traction unit with buckets, each of which is made with perforation and a tray located under its bottom, and a means for removing impurities from the load, characterized in that, with In order to improve the quality of cargo cleaning during the work of the elevator with grain, each bucket is equipped with an emphasis rigidly fixed on its bottom, while each tray is fixed on top of the corresponding bucket pivotally in the place where the latter adjoins the draft the spring and relative to the bucket with the possibility of interaction with the stop, and the means for removing impurities from the load is made in the form of blinds with a pipe located parallel to the load-bearing branch of the traction body between the latter and the casing wall.
