Abstract

The invention relates to devices for transferring bulk materials and can be used in ore dressing, metallurgical, construction and other industries of the national economy. The purpose of the invention is the reliability of work. The scraper feeder contains frame 1 mounted under the bunker 12 with shafts 2 and 3, on which stars of larger diameter 4 and smaller diameter 5 and asterisks 6 of the same diameter are mounted. Since the diameters of the extreme drive stars 4 are larger than the internal 5, the scraper contours move with distributed by linear velocity. The movement of the working circuits, driven by driving sprockets of different diameters, in one plane is ensured by the deflecting rollers 7 and due to the possibility of free rotation of the stars. daughter 6 relative to the shaft 3. 3 Il. a (L

Description

1

The invention relates to a device for transferring Slurry: nx materials and can be used in ore dressing, metallurgical, construction, and other: branches of the native host.

The purpose of the invention is to ensure reliable operation.

Fig, 1 shows the general view; Fig 2 - the same, top view; "And fig.Z - section aa in figure 2 o

Scraper feeder contains, installed on it drive 2 and end 3 shafts. Drive sprockets of large diameter 4 and smaller diameter 5 are placed on the drive shaft. The end shaft is equipped with end sprockets 6 with identical diameters.

Rollers 7 are installed on the frame of the drive sprockets, which allows placing scraper contours with greater speed 8 and lower speed 9 on a flat platform of 10 ° C The end sprockets and closing contours with a lower speed can rotate freely relative to the end shaft. The feeder is equipped with bolts I1 and is located under the bunker 12 "

Overloaded material enters the conveyor 3.

The feeder works as follows

The horn mass from the bunker 12 enters the platform 10 and is carried by the scraper loops 8 and 9 in the direction of discharge.

Due to the fact that the diameters of the edge ™ of them drive sprockets 4 are larger than 5 mm in diameter, there are 5 stars, that is scraper

the contours, and with them the load above them move at different linear speeds. Thanks to this, the rock mass is evenly fed to the sub-conveyor belt 13. Moving the working circuits in the same plane, driven by driving sprockets of different diameters fixed rigidly on one shaft 2, is provided by deflecting rollers 7 mounted on the frame 1 and the end sprocket 6 with respect to the shaft 3 eliminates jamming of the material, reducing the dynamic loads on the drive elements and the traction chains.
