Description

This invention relates to screw. conveyors used for loading bulk materials prone to accumulation.

The purpose of the invention is to improve the performance of the conveyor by effectively cleaning the screw surface of the conveyor during transportation of materials prone to slip.

Fig, 1 shows a screw conveyor, obschny VU Sh; fig 2 - section aa on. FIG. 1 with a; wedge at the moment of screw cleaning, in fig. 3 - the same, with the scraper at the time of the reverse cleaning device; in FIG. 4, section BB, in FIG. 2. (,

The screw conveyor of sodersch-yy kozkuh 15 in which holes 2 and 3 are made, respectively, for holding the cargo unloading material, and shaft 4 with screw 5, Kok; /.; -; it is provided with longitudinal directions for Ge in which the carriage 7 is placed, and a wedge support 8, and an emphasis 9 is placed on the surface of the screw.

On the carriage, with the possibility of rotation — on 90 about an axis 10 — there is a scraper 11 p connected, with a carriage 12, mounted; The line is deysogvi which in extreme positions: the scraper is located in the thule. or higher OCF rotation, ensuring a stable position of the scraper in extreme burns

In the lowermost position, the scraper 11 contacts with. with screw 5 and during rotation of the latter, in the test with the carriage 7, it is possible to move along the screw to the right.

The carriage 7 is connected by means of a flexible elm 13 to the reverse mechanism 14 e executed in the video of the drum 15 and the torsion spring 16; S os the scraper to the working surface of the Eint and the scraper to the left when removing the scraper 11 from the contact: with screw.

The fascia: e 1 with the possibility of interaction with the stop 17, mounted on 7, is fitted with an exhaust clamp 18; with a bevel K at the end,

The latch is provided with a pin 19 to spring-loaded relative to the casing by the spring 20.

 The screw conveyor works as follows.

Transported material through hole 2 gets inside.

1 and, when rotating the shaft 4 with the screw 5, is fed to the discharge opening 3. In this case, the carriage 7 with the scraper 11 raised to its extreme position is located in the discharge area

the window and is prevented from moving by the latch 18. which contacts the carriage 17.
