花生脱壳机脱壳装置表面改形设计与试验研究

Surface modification design and experimental study on shelling device of peanut shelling machine

针对目前花生脱壳机械存在的主要问题,对脱壳装置击打部件的表面进行改形设计,即采用实心铁质螺旋线形式;凹板筛的筋条间距设定为9mm,凹板筛与打板的距离设定为13mm。性能试验结果表明,实心螺旋线形式的击打部件整体优于空心铁管,转速在330r/min时,脱净率为99.88%、损伤率为0.78%。

Aiming at the main problems existing in the peanut shelling machine, the surface of shelling device hitting parts were changed shape design, which used a solid iron helix; concave plate sieve rib spacing set to 9mm, the distance of concave plate sieve and the beater set to 13mm. Test results showed that the solid spiral form hitting parts overall is superior to the hollow iron pipe, when speed is 330r/min, the net rate is 99.88%, and the damage rate is 0. 78%.
