AI Technical Summary
Technical Problem
Existing spiral drums have low lump coal yield and insufficient coal loading efficiency in thin coal seam mining, which are difficult to improve, and the cutting energy consumption is high.
Method used
The conical spiral drum design with double-jointed cutting teeth achieves coordinated crushing and improves coal loading efficiency through a conical hub and variable-diameter spiral blade structure, combined with gradually changing diameter and non-uniformly arranged cutting teeth.
Benefits of technology
It improves the cutting and coal loading capacity of the spiral drum, reduces the energy consumption of the cutting ratio, extends the service life of the cutting teeth, and increases the lump coal rate.

Abstract
一种采用双联型截齿的锥形螺旋滚筒，包括截齿、筒毂、螺旋叶片和端盘，所述筒毂采用锥形结构，端盘固连在筒毂直径较大一端，筒毂外侧呈螺旋状安装若干数量的螺旋叶片，螺旋叶片与端盘外侧安装若干数量的截齿。本发明在截割煤壁过程中，双联型截齿中的两个合金头会先后对煤壁进行破碎，能够有效降低单个截齿的受力，螺旋叶片上截齿间隔采用非均匀布置可提高煤炭的块煤率，锥形筒毂与变直径的螺旋叶片能够提高螺旋滚筒的装煤效率。
