平面床式齿光辊油茶蒲籽清选机研制与试验

Research and Test on Sorting Machine for Camellia oleifera Seeds with Plane Toothed Smooth Roller

为解决油茶果脱蒲后如何把茶籽从果蒲和茶籽的混合物料中清选出来这一难题,基于已有的齿光辊对辊清选技术,通过研究平面齿光辊对辊式清选机构,对齿光辊上移动的物料进行受力和速度分析,并设计扫籽机构和内外板可拆式轴承座,组合成平面床式油茶蒲籽清选机。对该机性能参数进行单因素试验,得出该清选机在齿光辊转速533~602 r/min、齿光辊间隙2.4~2.7 mm时,产量≥2 t/h,破籽率≤1.21%,损耗率≤1.05%,籽中含蒲率≤4.86%。该机为实现高效低损的蒲籽分离提供了技术支撑和设备支持。

In order to solve problem of how to separate tea seeds from mixture of fruit and tea seeds after shelling of Camellia oleifera,based on existing sorting technology of toothed smooth roller,force and speed of moving material on tooth smooth roller were analyzed by studying sorting mechanism of plane toothed smooth roller.Seed scavenging mechanism and detachable bearing seat of inner and outer plates were designed to form a plane bed type sorting machine for Camellia oleifera seeds.Single factor test was carried out on performance parameters of the machine.Results showed that when speed of toothed smooth roller was 533-602 rmin and clearance between toothed smooth roller was 2.4-2.7 mm,the output was≥2 th,seed breakage rate was≤1.21%,loss rate was≤1.05%,and seed percentage was≤4.86%.This machine could provide technical support and equipment support for separation of high efficiency and low loss of Camellia oleifera sorting.
