技术领域 本发明涉及一种称重装置, 特别涉及一种用于测量输送槽中输送的散状物料的 重量的称重装置。
背景技术 现有技术在测量输送槽中输送的散状物料时, 一般是采用冲板流量计。 冲板流 量计由检测板、 冲击传感器和测量仪表组成。 其工作原是: 当散状物料以一定 速度和角度沿滑槽冲击检测板时, 在检测板的作用下散状物料方向发生改变, 同时散状物料对检测板产生一个作用力, 该作用力在水平方向和垂直方向各有 一个分力, 该作用力与物料的流量存在一定的关系, 通过测量该力的大小即可 得出散状物料的流量, 该流量对时间积分就得到重量。 由于散状物料所含水份 不同、 粒度大小也不同, 导致散状物料在沿滑槽输送过程中速度极不均匀, 同 时当同一截面物料冲击到冲击板时, 中间和边缘物料的流速差别很大极不均匀, 这些因素使检测板上测到的冲击信号严重失真, 导致该种结构的称重装置的称 重误差普遍大于 2%。

冲击板的冲击面与散状物料的滑动方向之间的夹角 α满足以下关系: 10度 ^ α ≤100度。
在冲击板上设置有缓冲栅。
一种滑槽秤, 包括固定滑槽, 在固定滑槽上设置有流动的散状物料, 在固定滑 槽的末端连接有称重滑槽, 在称重滑槽的末端连接有出料槽, 在出料槽的末端 间隔的相互平行的设置有多个小冲击板, 在小冲击板上设置有第一测力传感器, 在称重滑槽上设置有第二测力传感器, 第二测力传感器和第一测力传感器均分 别与单片机电连接。
