Inclined belt conveyor


B65G15/22 - comprising a series of co-operating units

 

The invention relates to a continuous transport, in particular to the belt conveyors, and can be used as internal transport in various industries and in other areas. Inclined belt conveyor includes a belt covering driving device, tension device, deflecting drums and supporting rollers, with the formation of plots located at an angle to each other. The tensioner is made in the form of a drum mounted in the end portion of the conveyor. Drive unit is placed in the initial part of the conveyor at the loading area between load and no-load branches of the conveyor belt and contains closed on their own end reel tape around the outside of the conveyor belt, carrying the branch which lies on the upper branch of the belt drive device to move it along an area of the load from the tension pulley device to the point of inflection of the conveyor belt between arranged at an angle to each other areas. Increases reliability of the pipeline. 1 Il.

The invention relates to a continuous transport, in particular to a belt conveyor is the itsindustry and agriculture.

Known inclined belt conveyor, the ribbon, envelope end drums mounted on the angled one to the other of the suction and discharge sections of the frame with the start and end parts of the supporting rollers and two disks connected by axle mounted above the ribbon in her inflection at a sufficient distance from its edges.

However, the application of such disks narrow working width of the tape and creates resistance to the passage of goods at the site of the break, reducing performance.

Closest to the invention is a technical solution achieved the effect is inclined belt conveyor, which includes the ribbon, envelope end drums mounted on angled to one another loading and unloading areas of the frame, drive unit which is placed in the end portion on the discharge section, and a tension drum in the initial part of the plot of load supporting rollers, and the end part of the discharge section provided with stops located with the opportunity to interact with the supporting rollers mounted on the frame by means of elastic elements, allowing the rollers in the upper part of the conveyor when the deposits. In this regard, the tension of the working branch tape on the top of its area is increased, and the tension idle branch and working (before stretch braking rollers) decreases, which reduces the value of the tape tension at the site of the break working branch (ed. St. SU A, CL 65 G 15/08, bull. 9 from 07.03.85).

Along with the simplicity of this technical solution, it has some significant drawbacks that limit its scope, as it involves the application of mere flat bands at relatively small angles of inclination of the conveyor and cannot guarantee a reliable fit working (derrick) branch of the tape to the supporting rollers on the section of the curve, calculated for the effect of the friction tape on slow rollers, as the magnitude of the friction forces depend on the weather and climatic conditions and time of year.

The purpose of the invention is to ensure reliable operation of the pipeline by preventing separation of the carrying tape from the supporting rollers on the section of the curve, the less wear of ribbons and expansion of technological possibilities.

This goal is achieved by the fact that in an inclined belt conveyor including a belt covering driving device, tension fit the se, with the initial and terminal parts, the tensioner is made in the form of a drum mounted in the end portion of the conveyor and drive unit are placed in the initial part of the conveyor at the loading area between load and no-load branches of the conveyor belt and contains closed on their own end reel tape around the outside of the conveyor belt, carrying the branch which lies on the upper branch of the belt drive device to move it along an area of the load from the tension pulley device to the point of inflection of the conveyor belt between arranged at an angle to each other sites.

The drawing shows a diagram of an inclined belt conveyor.

Inclined belt conveyor includes a belt 1, covering the drive and tensioner installed in the initial and terminal parts, the deflecting drum 3 and the supporting rollers 4, forming sections I, II, III, located at an angle to each other. At the end of the discharge section III is the tension drum 2, which is a preliminary surface tension of the traction unit, and on the download site I between load and no-load branches conveyor belt placed anavah drums 6, 7 tape 5, around the outside of the conveyor belt 1, the load-carrying branch which lies on top of the tape 5 to the drive device based on the supporting rollers 4, and moves it along the site I download from the tension of the drum 6 of this device to the point of inflection, and the idle branch of the conveyor belt, clasping the reels 6, 7 on top of the tape drive device, firmly pressed against her lower branches deflecting drums 3 and together with her moves away from the drive pulley 7 to the tension 6. Traction belt is provided by friction between the branches of the tape drive device and the pipeline, mostly in their joint circumference of the drums 6, 7. (Coefficient of friction for gummed tapes=0.3 to 0.4). This resistance to movement of the load-carrying branch of the conveyor belt will only occur on slope and discharge sections II, III, allowing the same traction ability of the pipeline to reduce the tension of the tape to ensure its contact with the rollers on the plot of the curve and the magnitude of the resulting force, pulling the tape from these clips.

Thus, the point of inflection of the load-carrying branch of the conveyor belt will always be in raveline the angles of inclination of the conveyor is determined by the shape and physico-mechanical properties of the cargo and can reach 40o. The proposed construction of the pipeline involves the ability to change the angle and the use of both flat and troughed belts depending on the nature of cargo that extends its technological capabilities.
