SU45530A1 - Endless transporter - Google Patents

Description

In the development of non-minerals, for example, gravels, sand, etc., they are often clogged with harmful impurities to be removed, and also have a heterogeneous fractional structure, the improvement of which is usually achieved by screening.

In order to combine the operation of transporting the material mined in the quarry with the above-mentioned refining operations, the present invention proposes an endless conveyor with mesh tray sections periodically shaken to screen the transported material when the attached bottom fits to the links of the fists with supporting conveyor rollers.

In FIG. 1 shows the proposed side view conveyor; FIG. 2 - the same cross section; FIG. 3-plan of a part of a working cloth of the conveyor in the increased scale; FIG. 4-detail of attachment of the conveyor links to the traction chains m-view from below; FIG. 5 is a section along the line AB of FIG. four; FIG. 6 shows a section along the line DE of FIG. four.

The conveyor is composed of a head section 2 with a tension device and intermediate sections 3 connected to each other by means of linings 4 (Fig. 1). Head and tail section

provided with end drums 7 and S ,. and on the intermediate sections there are reinforced horizontal rollers 5 supporting the working belt 6 of the conveyor and vertical deflector rollers W-. The working belt of the conveyor is made up of box-shaped links, which are one to another and fitted with a mesh bottom 7 / (Fig. 3 and sides bent up 12. The conveyor link is attached to the traction plate chains 13 (Fig. 4, 5 and 6) by means of bolts 14, with staples 15 clamped between said bolts 14 between each plate of the chain and the link of the conveyor attached to it.

The traction chain plates are pivotally interconnected by means of bolts 16 inserted into the lugs at the ends of the joined plates, which are stitched. in the form of razviliny 18 and ridge 17; Two fists 19 are attached to each third link of the conveyor. As the conveyor moves, these fists overlap the support rollers 5 and raise the working belt of the conveyor, which, when the fists 19 slide off the rollers 19, is shaken and subjected to the screening of the material lying on it. At the same time, the trifle, passing through the mesh cloth, falls on

7 located underneath, an inclined sheet 20 (Fig. 2), along which spill-to-side. For the simultaneous passage of the transported material over the working surface of the conveyor belt, along the latter, there is a water main 27 (Fig. 3), to which the mesh tubes 22 are attached, which spray water. In addition, above the working surface of the conveyor belt are located at a certain angle to the direction of movement of the tape shields 23, by means of which the gear constantly moves from the "paradise of the canvas to the middle and back,

mixing with it and contributing to a more complete ennobling.

The subject matter of the invention.

An endless conveyor, the working web of which is composed of recurring trays of links with a mesh bottom and attached to hinge traction chains, characterized in that, in order to sift the transported bulk material, the links are periodically shaken during the interaction of the fists attached to it from below 7P with rollers supporting the conveyor belt.
