摘　　要：针对埋刮板输送机在输送不同物料时存在刮板节距如何确定的问题,以MS型、MC型埋刮板输送机为研究对象,分析了刮板面积、机槽高度与宽度、输送物料等影响因素对刮板节距的影响规律。分析结果表明,相比较而言,输送物料的不同对刮板节距的影响较大。对于MS型埋刮板输送机,在其他因素不变的情况下,刮板节距随着刮板面积的增大而增大,随着机槽宽度与高度的增大而减小;不同的物料由于内摩擦角不同,刮板节距呈现先减小后增大的情况,在25°左右达到最小值。对于MC型埋刮板输送机,当增大刮板宽度时,刮板节距减小;而增大刮板高度时,刮板节距随之增大;当输送内摩擦角为30°的物料时,刮板节距为最小值。In order to solve problem of how to determine scraper pitch when en-masse conveyors transported different materials,MS and MC en-masse conveyors were taken as the research object,the influence law of the scraper area,conveying material,machine slot height and width on the scraper pitch were analyzed.The analysis results show that the different conveying materials have a great influence on the scraper pitch.For MS en-masse conveyor,the scraper pitch increases with increasing of the scraper area and decreases with increasing of slot width and height when other factors remain unchanged.Because the internal friction angles of different material are different,scraper pitch decreases first and then increases,at about 25°to the minimum.For the MC en-masse conveyor,scraper pitch decreases as the scraper width increases,and increases as the scraper height increases.When the internal friction angle is about 30°,the minimum value of scraper pitch is obtained.
