    • A sifting shovel for sifting particulate matter from a volume of material comprising a shovel head and a handle with an end fixed to the shovel head. The shovel head has a base plate, a sifting plate disposed in spaced relation relative to the base plate, a first side wall, a second side wall, and a proximal end wall. The sifting plate has a plurality of apertures therein, and the base plate, the sifting plate, and the first and second side walls have distal ends that together define an open mouth of the shovel head. The open mouth can have a minimum opening height greater than a maximum aperture dimension, and the shovel head can have a truncated wedge shape. At least a portion of the handle can be disposed below a longitudinal center of gravity of the sifting shovel, such as by forming a bend in the handle, to enable the sifting shovel to tip automatically.
    • 一种用于从包括铲头和手柄的材料体积中筛选颗粒物的筛子铲,其端部固定在铲头上。 铲头具有基板,相对于基板间隔设置的筛板,第一侧壁,第二侧壁和近端壁。 筛板在其中具有多个孔,底板,筛分板以及第一和第二侧壁具有一起限定铲头的开口的远端。 开口可以具有大于最大孔径尺寸的最小开口高度,并且铲头可具有截头楔形。 手柄的至少一部分可以设置在筛筛铲的纵向重心下方,例如通过在把手中形成弯曲部,以使得筛网铲自动提升。
