一种生物质切割装置

Abstract

本实用新型涉及生物质切割工装技术领域，具体涉及一种生物质切割装置，生物质切割装置包括筒体、刀盘、回转驱动器和压块；筒体的两端面上对应开设有进料口和出料口；刀盘和压块均内置于筒体；刀盘与筒体同轴设置；刀盘的径向上设置有第一割刀；第一割刀的切割面的直径不小于筒体的内径；回转驱动器外置于筒体；刀盘的第一端与回转驱动器的输出轴连接；刀盘的第二端设置有压块；压块的自由端构造为弧形板；弧形板的外壁朝向筒体的内壁，且弧形板与筒体同轴设置。相较于直线推进型切割的方式而言，单向旋转型切割的方式消除了割刀的空跑路径，割刀旋转一圈即完成一次切割，避免了行程浪费，进而降低了设备能耗，提升了切割效率。
