    • PROBLEM TO BE SOLVED: To develop a pitch controller which is capable of reducing bush wear caused by the application of pressure by a yoke in a concrete finishing trowel, has a folding handle, does not require physical operation for a thrust collar, and requires only a few number of operations with fingers. SOLUTION: A concrete finishing machine comprises both a rotatable trowel blade assembly and a mechanism for controllably adjusting the pitch of trowel blades to the surface of a concrete in a wet state on which the trowel blades are mounted. By using the rotation of a drive shaft of an engine of the machine itself, the pitch is changed. COPYRIGHT: (C)2004,JPO&NCIPI
    • 要解决的问题:为了开发一种能够减少由混凝土精整抹子中的轭施加压力引起的衬套磨损的变桨控制器,具有折叠手柄,不需要用于推力环的物理操作, 并且手指只需要少数操作。 解决方案:混凝土整理机包括可旋转的t刀刀片组件和用于在其中安装t刀刀片的湿润状态下可控地将t刀刀片的间距调整到混凝土表面的机构。 通过使用机器本身的发动机的驱动轴的旋转,音调被改变。 版权所有(C)2004,JPO&NCIPI
