Novel screw blade of screw feeder

The utility model discloses a novel screw blade of a screw feeder, which comprises a screw blade and is characterized in that an anti-abrasion mechanism is further arranged on the circumferential boundary of the screw blade, and the anti-abrasion mechanism is fixedly connected with the screw blade. The spiral blade is repaired, the surface material hardness of the spiral blade is improved, the service life of the spiral blade can be effectively prolonged, the production influence caused by replacement of the spiral blade is reduced, meanwhile, the cutter is additionally arranged on the spiral blade, hardened objects on the inner wall of the spiral feeder can be well removed, the operation load of the feeder is reduced, and the service life of the spiral feeder is prolonged. And the power consumption cost is reduced. 本实用新型公开了一种新型的螺旋给料机螺旋叶片，包括螺旋叶片，其特征在于，所述螺旋叶片的圆周边界上还设有防磨损机构，所述防磨损机构与所述螺旋叶片固定连接。本实用新型通过对螺旋叶片进行修复，提高螺旋叶片表面材质硬度，能有效提高螺旋叶片的使用周期，减少因螺旋叶片更换造成的生产影响，同时在螺旋叶片上增加刀具，能较好清除螺旋给料机内壁板结物，减轻给料机运行负荷，降低电耗成本。
