Abstract
An apparatus for removing stone and gravel from excavated soil by vibration. The apparatus is particularly useful for operation at the foot of a volcano, mountainous district or the like. Characteristic features of the apparatus are that it is self-propelled by means of endless tracks and the excavated soil is separated into stone, gravel and soil with the aid of a sieving means and the separated stone and gravel are discharged from the apparatus by way of a conveyor, while the separated fine soil is conveyed by way of another conveyor and then is scattered rearward by means of a scattering device to be piled up on the working ground.
