SU107260A1 - Inclined belt conveyor - Google Patents

Description

Transportation to the height of wet and sticky materials (wet sand, molding soil, etc.) using bucket elevators is difficult due to sticking of the buckets and stopping the feeding of the material. The use of conventional belt conveyors for this purpose requires large production areas and multiple material overloads, since the conveyors have a limited lifting angle.

Inclined belt conveyors are known for transporting such materials; their upper branch, attached to the links of two parallel lamellar chains by means of levers, is formed in the form of pockets for the material being transported. In such conveyors, when the upper drum is bent, the belt is straightened and the lifted material is poured into the receiver.

A disadvantage of the known conveyors of this type is the lack of a relatively simple mechanism for the automatic formation of pockets on the inclined lifting branch of the conveyor.

The inclined belt conveyor according to the invention is free from this disadvantage.

CyniHocTb of the invention consists in that a device for alternately directing the rollers of adjacent links of the traction chains to the top, then to the lower surface of the guide chains is used to automatically form pockets on the tape.

The fixture is made in the form of sectors that are rotatable around a horizontal axis and located opposite the guides for the rollers of the chains of the upper branch and are equipped with lateral h. Sectors are located at the transition point of the horizontal section of the upper branch in the oblique.

FIG. 1 shows a schematic side view of the conveyor; in fig. 2 is a device for automatically forming pockets for cargo on the tape (on an enlarged scale).

Under the loading funnel 1 is a horizontal section 2

flexible conveyor belt 3. The tape is attached to the crossbars 4 attached to oppositely located links of 5 t hinge chains 6. Rollers 7 are installed in the hinges of the chains, rolling along the upper and lower surfaces of the guides 8 for the upper branch. For the automatic formation of pockets on the working strip of the load pockets, a device is designed in the form of two sectors 10 rotatable around a common transverse horizontal axis 9, adjacent to the chain guides 8 at the point where the horizontal conveyor section becomes inclined. Above and below the sectors, there are curly tires 11 for guiding the rollers 7 of the tread chains 6. The driving sprockets 12 and 13 are installed at the receiving and unloading ends of the conveyor belt.

At the upper drive sprocket, the tape is straightened and the lifted material is fed through the funnel 14 to the receiver 15.

The action of the conveyor is as follows.

From the feed hopper, the transported material enters the horizontal section of the belt. When the belt is moved, the rollers carrying it enter the figures, between which the rotary sectors are located, and are subsequently guided between one of the shaped guides and the upper or lower surface of the sector. In the case of a roller moving between the top figure and the sector surface, the roller falls on the top surface of the guide for the pull chain. Under the action of the roller, as it approaches the guide for the pulling chain, the sector turns under the action of the roller and opens the way for the next roller only along the lower figured band. Consequently, the second roller that runs behind the first one falls only on the lower surface of the guide for the traction chain. Moving the roller along the lower tongue, when it approaches the guide for heavy use, zepku turns the sector to a position where the path for the next roller opens. the guide for the chains of the conveyor belt is automatically alternated.

The movement of the rollers of the adjacent links of the traction hinge chain causes a fracture of the links in the hinges and the formation of pockets from the tape for the transported material.

With the rollers coming off the guide at the upper sprockets, the tape is straightened and the material is poured into the receiver, and the tape is cleaned with a scraper.
