摘要刮板式花生剥壳机主要是利用高速旋转的刮板与花生果撞击以及和编织网凹板配合对花生果进行挤压，使果壳破碎与花生仁分离。针对花生剥壳机的发展概况和现有结构类型特点，进行花生剥壳机的方案设计和总体结构设计；通过对比分析国内外现有花生剥壳机构的类型及原理，选择功用较好的类型即开式扁钢条滚筒，编织网凹板花生剥壳机构，但是将扁钢条换成刮板可增大与花生果的接触面积，使花生果受到的作用力分布更均匀，破碎更完全；同时缩小刮板底部与编织网凹板表面的距离，使未剥净的花生果在此位置经受第二次挤压，提高一次剥净率。确定最后整体结构布局。通过对现有的几种花生剥壳部件的优缺点分析，采用刮板式、编织网凹板花生剥壳机，刮板可增大与花生果的接触面积，使花生果受到的作用力分布更均匀，破碎更完全；同时缩小刮板底部与编织网凹板表面的距离，使未剥净的花生果在此位置经受第二次挤压，提高一次剥净率。最后进行花生剥壳机的各个部件的结构设计及参数计算，主要包括电动机的选择、V带传动的设计、轴的设计、执行机构的设计以及箱体和支架的结构设计等。83284

AbstractScraper type peanut sheller is mainly by high speed rotating scraper and peanut impact and woven net concave with to the peanut fruit squeeze, the shell crushing and peanut kernel separating。 Peanut sheller for the development situation of and the existing structure features, peanut sheller design and overall structure design; through the comparative analysis of domestic and foreign existing peanut hulling mechanism types and principles of, choose the better function type that open flat steel drum, netting concave peanut hulling mechanism, but the flat steel bar for scraper can increase the contact area with peanuts, peanut fruit by the force distribution is more uniform, more broken completely; while reducing the scraper and the bottom of the braid concave surface distance, not peeling peanut fruit net in this position to withstand the second extrusion, improve a husking rate。 Determine the overall structure of the final layout。 The advantages and disadvantages of several existing peanut shelling component analysis, adopts scraper, woven net concave peanut sheller, scraper can increase contact area with peanuts, peanut fruit by the force distribution more uniform, more broken completely; while reducing the scraper bottom and weaving concave surface distance, not stripping net of peanut fruit in this position to withstand the second extrusion, improve a husking rate。 The peanut sheller in various parts of the structure design and parameter calculation, mainly comprises a motor, a V belt drive design, shaft design, execution mechanism design and a box body and a bracket structure design。
