Underground Coal Blet Conveyortype SGD420/22 Mine Equipment Mining Crawler Transporter Chain Scraper Conveyors

Product DescriptionIntroduction Of SGD420/22 Type Scraper Chain ConveyorSGD420/22 type scraper conveyor is mainly used for conveying coal in the shrinking thin coal seam blasting working face, which can be used for horizontal transportation or for inclined transportation. When transporting along an inclined upward direction, the inclination angle of the coal seam shall not exceed 25°, and when transporting downward, the inclination angle shall not exceed 20°. When the inclination angle of the coal seam is large, an anti-skid device shall be installed. The baffle plate on both sides of the central trough can be used to transport coal in the trough.  Structure Of SGD420/22 Type Scraper Chain ConveyorThe transmission part of SGD420/22 type scraper conveyor is mainly composed of motor, shaft, reducer, drive sprocket, chain tensioner, blind shaft and head frame. The motor, reducer and headstock are in a parallel arrangement.The matching motor of SGD420/22 type scraper conveyor is YBS-22-4 type explosion-proof motor. For the full load start, the starting torque and maximum torque of the motor are both 2.7 times the rated torque. The temperature rise of the motor is large, and it can operate well under frequent starting conditions.The SGD420/22 type scraper conveyor adopts JS-30 type reducer, which is a three-stage deceleration and involute gear transmission. The total transmission is 22.24. The first stage is a circular bevel gear, the second stage is a cylindrical helical gear, and the third stage is a cylindrical spur gear.The headstock is an integral welded component. The drive sprocket axis hole is the positioning hole for installing the reducer or blind shaft. There are holes for inserting the chain hooks on the upper edges of the head frame. Each side plate has a φ200 and six φ26 holes for mounting the reducer.The chain tensioning device is used for squeegee conveying, installing, dismounting or changing the laying length and tightening the squeegee chain when adjusting the tightening force. The chain tensioning device comprises two parts of a chain hook.Advantage Of SGD420/22 Type Scraper Chain  Conveyor1. The structure is solid. It can withstand the external forces such as punching, smashing, smashing and pressing of coal, vermiculite or other materials.2. It can adapt to the need of unevenness and bending of the bottom surface of coal mining face, and can withstand bending in vertical or horizontal direction.3. the body is short, easy to install.4. can double as the track of the shearer operation.5. can be reversed to facilitate the handling of the bottom chain accident.6. can be used as the fulcrum of the front section of the liquid night stent.Parameters Of SGD420/22 Type Scraper Chain ConveyorModelSGB420/22SGB420/30SGB420/40XSGB620/40SGB620/55)SGB620/80Delivery Capacity  (t/h)6080100150150150Standard length(m)80100100100100160Chain speed(m/s)0.880.880.860.860.860.86Electric motorsModel numberJDSB-22JDSB30JDSB40DSB40DSB55DSB40Power(kW)22304040552*40Voltage(V)220/380380/660380/660380/660380/660380/660Scraper chainFormSide double-strandedSide double-strandedSide double-strandedSide double-strandedSide double-strandedSide double-strandedChain size(mm)14*5014×5018×6418×6418×6418×64Breaking load(KN)≥250≥250320≥320≥320≥320Middle Flute size          (L x W x H)1200×420×1501200×420×1501200×420×1801500×620×1801500×620×1801500×620×180Total weight(t)8.510.61617.817.928.6PicturesPictures Of SGD420/22 Type Scraper Chain Conveyor Of SGD420/22 Type Scraper Chain Conveyor  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
