    • An easily adjustable grader for sizing and sorting food products, especially shellfish such as shrimp. The grader includes a series of parallel rotating rollers attached at either end to drive chains. The drive chains include adjustment levers attached rotatably at each roller position. The levers have a first arm terminating in a rolling wheel and a second arm whose end conforms to the chain. An adjustment rail is positioned above each chain along the length of the grader. The wheels of the levers ride along cam surface on the underside of the rail. Rail adjusters at each end of the rail raise and lower each end of the rail to change the spacing between the cam surface and the chain along the length of the grader. The pressure exerted by the cam surface on the lever causes the chain to kink in proportion to the distance between the cam surface and the chain, which adjusts the gap between consecutive rollers. The widths of the gaps determine the size gradations of the grader.
    • 一种容易调整的分级机,用于对食品进行分级和分选,特别是虾类如虾类。 平地机包括一系列平行的旋转辊,两个连接的滚轮连接在驱动链的两端。 驱动链包括可旋转地附接在每个滚子位置的调节杆。 杠杆具有终止于滚动轮的第一臂,其末端符合链条的第二臂。 调整轨道沿着分级机的长度位于每条链上方。 杠杆的轮子沿着轨道下侧的凸轮表面。 轨道两端的导轨调节器升高和降低轨道的每端,以沿着分级机的长度改变凸轮表面和链条之间的间距。 凸轮表面施加在杠杆上的压力导致链条与凸轮表面和链条之间的距离成比例地扭转,这调节连续辊之间的间隙。 间隙的宽度决定了分级机的尺寸等级。
