Abstract: A raised wall for hoppers. The wall has one panel with opposing ends arranged for connection to corresponding ends of an adjacent panel. The wall further has a seal applied between adjacent panels at a connection. The panel comprises a plugging surface with longitudinal edges configured to be joined in a superimposed manner on an adjacent edge. The longitudinal edges are interrupted in the region of the connection of the seal where the panel is continued by the single plugging surface. The seal comprises a first surface which abuts the plugging surface from the hopper exterior, a second surface which abuts the plugging surface from the hopper interior, and a bridge between the two surfaces delimiting a channel which receives the plugging surface of at least one of the adjacent panels for covering and blocking the gap generated by the interruption of the edges.

Abstract: A device for processing the soil comprises a frame which carries at least one processing tool and at least one resilient element which has a first end portion which is associated with the processing tool and a second end portion which is associated with the frame by means of connection devices. The connection devices comprise a first laminar element which is arranged in an upper position with respect to the second end portion of the resilient element and a second laminar element which is arranged in a lower position with respect to the second end portion. The connection devices further comprise a separator device which is arranged between the first laminar element and the second laminar element which is capable of forming a separation between the second end portion and the laminar elements which defines a cavity between the first laminar element and the second laminar element, inside which the resilient element can bend.
