The utility model relates to a toper sand prevention screen pipe, including wire winding, edge the rib that wire winding circumference was evenly arranged, the wire winding winding the rib forms wholetaper. For judging whether accidental shutdown provides the reference to the wire drawing machine, guaranteed the order of production, also guaranteed the production safety. Conical sand prevention screen pipe installation resistance is little, and the one end size of keeping away from ground is little, and structural strength is big, and the pressure -bearing structure is more reasonable. 本实用新型涉及种锥形防沙筛管，包括绕丝、沿所述绕丝周向均匀布置的肋条，所述绕丝缠绕所述肋条形成整体锥状。为判断拉丝机是否故障停机提供了参考，保证了生产的有序性，也保证了生产安全。锥形的防沙筛管安装阻力小，远离地面的端尺寸小，结构强度大，承压结构更加合理。
