粉碎装置和清理土地的方法
Shredding apparatus and method of clearing land
US-7584921-B1用于粉碎植被以清理土地。
专利摘要
一种粉碎装置利用圆柱形滚筒，用于快速有效地清理大片土地。多个刀块以两排螺旋状布置在滚筒周边，并通过焊接固定在滚筒上。每排中的刀块彼此间隔一定轴向距离，以便在滚筒旋转时提供对土地的完整扫掠。每个刀块包括可更换的切割齿。每个齿包括锚固在每个刀块孔中的柄。至少一个刀块沿滚筒的每个边缘安装，向外倾斜约2°至约15°的小角度，并向外倾斜约2°至约5°，使得其相应的齿提供对滚筒边缘的保护。所有其余刀块安装成齿与滚筒轴线平行。
Original abstractA shredding apparatus utilizes a cylindrical drum adapted for quickly and effectively clearing large tracts of land. Several blocks are positioned in two spiral rows on the periphery of the drum and are secured to the drum by welding. The blocks in each row are spaced from one another an axial distance that provides a complete sweep of the land as the drum rotates. Each of the blocks includes a replaceable cutter tooth. The teeth each include a shank that is anchored in a hole in each block. At least one block is mounted along each edge of the drum at a slight outward angle between about 2°, and about 15°, and is tilted outwardly between about 2° and about 5° so that its corresponding tooth provides protection of the drum edge. All of the remaining blocks are mounted so that the teeth are parallel with the drum axis.
