Zhongbo wish everyone a Happy New Year . Today I will introduce scalable delivery structure to provide our customers be able to learn more about the conveyor .

    Telescopic belt conveyor , compared with ordinary belt conveyor , its working principle is the same, but the structure differ, it increases the retractable tape devices and tape storage devices. Why is it called telescopic belt conveyor it? That is because : When swimming in the tail end of the car moves, the tape into the tape storage device , tail retraction ; otherwise tail extension , therefore scalable , so called telescopic belt conveyor . Today we introduce its structure, including the nose gear, retractable tape device , the intermediate frame and the feeding device , cutting device .

     Telescopic belt conveyor is divided into two parts fixed and non-fixed part of the fixed part of the nose gear, tape storage devices , retractable tape devices and other components ; non-fixed portion of the bracket is no quick detachable bolted , tail and other components.

     1 head gear

     By the drive rolls, reducers , hydraulic couplings , racks , unloading roller cleaner composition .

     Nose gear is part of the whole conveyor drive , two motors through hydraulic coupling, reducer transmission torque respectively to the two drive rollers , when used gear , remove a group of motor , hydraulic coupling and reducer.

     Hydraulic coupling of YL-400 type , which consists of a pump wheel, a turbine wheel constituting the housing , a driven shaft or the like , which is characterized with a secondary side of the pump wheel chamber , the motor starts , the flow through the orifice into the working chamber , and thus make more balanced load and start the motor press close to Kennedy set to start , plus No. 20 machine oil when working within the housing , oil-filled volume of 14m3, using higher gear reducer , the first stage of the arc cone gear , second and third level of helical and spur gear , the total ratio of 25.564 , and SGW-620/40T scraper conveyor can be interchangeable , reducer directly connected to the frame by bolts .

     Unloading a head end and a cleaning device with backstop facilitate unloading, the front nose portion extending outwards unload arm , extending from the unloading roller and frame composition , the roller mounted on the frame extends , the axial position of the bearing can be both sides of the bolt is adjusted to adjust the deviation of the tape in the machine head , is mounted at the lower ends and two unloading roller cleaning device , the cleaning blade is pressed against the tape, the adhesion of the pulverized coal can be removed when the belt backstop to prevent parking tape rewind.

     2 retractable tape device

     Located at the rear tensioning winches , which consists of a rack , aligning roller, reducer, motor , rotating rod , etc., whose role is to supplement the conveyor belt or remove it from the body conveyor fuselage, and rear ends of the frame , each fitted a rotating rod for clamping master tape when the tape increases or decreases when the group retractable reel tape guide for aligning roller , working to promote the roll rack from the top end of the tail with the other end of the top in the top of the shaft reducer , starting motor through reducer dial drive shaft of the reel , reel tape, release the tape , do not open from the outside when the motor drive tape released roll reversal, rail when not in work activities available plug hanging on the rack in order to narrow the width of the track should be set above the active suspension roll lifting device , depending on the particular circumstances appropriate roadway width broadened to facilitate tape revenue operation .

     3 . Middle frame

     Quick detachable bracket bolted from the free by the H- frame, steel, flat roller and hook-type trough idlers , "V" -type roller , etc., is a non-fixed part of the machine , steel can be used as demolition machine body, with studs mounted on a solid steel , with a hammer can move , hook-type trough roller bonding type, slotted angle of 30 °, with hooks for hanging on steel studs , hooks arc on the brake gullet , roller is hanging on by alveolar studs , you can move forward backward to adjust the position of the control idler belt run .

     4 . The feeding device , cutting device

     Feeding device mounted behind retractable device , guided by a steering turn connected to the material, material transported from the material shipped to the lower section of the upper loading , unloading device consists of a set of oblique cutting roller segment the material removed under extremely direct feed section , the tail and the tail drum seat rails composed rails bolted to the end of the bracket , and with plastic front with another peg rail access , in order to adapt to the uneven floor , tail roller and with the same storage device in the drum structure, interchangeable , its axis position adjustment bolts are available to adjust the tape deviation in the tail , tail drum front plate with a scraper coal , a coal can drum surface or pink coal scraped and collected mud bath , with a special pull the fender out, plus with buffer tail idlers , when the subject material , which reduces the impact of lump tape , the tape will help improve life .
