A sowing element comprising:
- a frame;
- a box-shaped body that is fixedly mounted on the frame and provided with an opening;
- a perforated disc that is rotatably supported in the box-shaped body and has opposing faces which can be subject to a pressure differential;
- a pressurisation device associated with said disc for applying said pressure differential to said faces
- said pressurisation device including a pressurisation bell combined with said disc so as to pneumatically couple thereto in order to guarantee said pressure differential;
- wherein the bell is idly rotatably supported on a supporting structure mounted on said box-shaped body, said supporting structure being configured such that the bell contacts the disc when the supporting structure is mounted on said box-shaped body, wherein the bell is not mechanically coupled with the disc, and when the bell contacts the disc, the bell is coupled to the disc for dragging.
