    • A conveyor belt cleaner and tensioner assembly including a conveyor belt cleaner and a conveyor belt cleaner tensioner. The conveyor belt cleaner includes a scraper blade assembly having a mounting member and a scraper blade. The mounting member includes a base member adapted to be attached to a cross shaft and first and second flanges extending outwardly from the base member forming a first slot therebetween. The scraper blade includes a mounting base having a bore through which the mounting member extends, second and third slots adapted to receive the first and second flanges of the mounting member, and a third flange adapted to be inserted in the first slot of the mounting member such that the scraper blade is rotatably attached to the mounting member. The tensioner includes a support arm rotatably attached to a rotatable tensioning rod and a pivot arm pivotally attached to the support arm which receives the cross shaft. A biasing member extends between the support arm and the pivot arm. Rotation of the tensioning rod moves the support bracket and pivot arm along the tensioning rod until the scraper blades engage the conveyor belt, whereafter continued rotation of the tensioning rod compresses the biasing member to resiliently bias the scraper blades into engagement with the conveyor belt.
    • 输送带清洁器和张紧器组件,包括输送带清洁器和输送带清洁器张紧器。 传送带清洁器包括具有安装构件和刮刀的刮刀组件。 安装构件包括适于附接到横轴的基部构件和从基部构件向外延伸的第一和第二凸缘,其在它们之间形成第一狭槽。 刮刀包括具有安装构件延伸的孔的安装基座,适于接收安装构件的第一和第二凸缘的第二和第三槽,以及适于插入安装构件的第一槽中的第三凸缘 使得刮刀可旋转地附接到安装构件。 张紧器包括可旋转地附接到可旋转张紧杆的支撑臂和枢转地连接到支撑臂的枢转臂,该支撑臂接收横轴。 偏置构件在支撑臂和枢转臂之间延伸。 张紧杆的旋转使支撑托架和枢转臂沿着张紧杆移动,直到刮刀接合输送带,然后张紧杆的继续旋转压缩偏置构件以弹性地偏压刮板与传送带接合。
