1. A device for processing soil comprising:
a frame which carries a processing tool;
a resilient element which has a first end portion connected to the processing tool and a second end portion connected to the frame by a connection device;
wherein the connection device comprises:
a first laminar element and a second laminar element, the second end portion of the resilient element being interposed between the first laminar element and the second laminar element, the first laminar element and the second laminar element being disposed above and below the resilient element, respectively;
a separator arranged between the first laminar element and the second laminar element in a region of the second end portion of the resilient element, and the separator forming a separation between the second end portion and the laminar elements, the separation defining a cavity between the first laminar element and the second laminar element, wherein the resilient element is bendable in a vertical direction towards and away from the first or second laminar elements inside the cavity itself;
a first shaped plate and a second shaped plate in contact with the first laminar element and the second laminar element, respectively;
the first shaped plate and the second shaped plate each comprise a first portion and two second portions of elongate form, the second portions extending from the first portion in a manner substantially parallel with each other;
the second portions have lateral surfaces facing each other and which are separated by a separation distance; and
the resilient element has a transverse dimension, an extent of which is less than the separation distance, at least in proximity of the second end portion.
