The core logic of the scraping and breaking arch valve does not rely on vibration or airflow impact, but rather uses mechanical force to forcefully break the "arch bridge" built by the material. The motor drives the transmission structure (commonly gears or vortex rods) to operate, transmitting power to the scraper. The scraper is installed at the bottom of the silo and moves in a circular motion around the silo wall, continuously rotating against the bottom of the material pile up. The rotating scraper directly cuts and agitates the bottom of the material, breaking the arch structure formed by the mutual support between the material particles. At the same time, it can also scrape off the material stuck to the warehouse wall, allowing the material to fall again under the action of gravity. ‌‌

　　刮料破拱阀核心逻辑不靠振动、也不靠气流冲击，而是用机械力硬性破除物料搭起来的“拱桥”。电机带动传动结构(常见的是齿轮或涡杆)运转，把动力传给刮板。刮板安装在料仓底部，绕着仓壁做圆周运动，贴着物料堆积的底部持续旋转。旋转的刮片直接切断、搅动物料底部，破坏物料颗粒之间相互支撑形成的拱形结构，同时也能刮掉黏在仓壁上的料，让物料在重力作用下重新下落。‌‌
