摘要：
A system (100) for processing soil has been disclosed. The sytem comprises a soil processing device (110), arranged to be moved on a soil surface; and a driving device (160) arranged to move the soil processing device (110) on a portion of the soil surface (170). The soil processing device (110) includes a frame (112), arranged to slide or roll on the portion of the soil surface (170) during operation of the system (100); and at least one substantially horizontal pipe (114), attached to the frame (112), extending along an underside of the frame (112), at a predetermined depth. The pipe (114) has apertures (116) and is connectable to a vacuum generating device that provides an underpressure in the pipe (114). In order to avoid packing of particles or material in the apertures, the pipe (114) is provided with a collar (502) around its perimeter. The collar (502) is configured so as to shield the apertures (116) from surrounding soil, while also facilitating movement of the pipe (114) through the soil.
