1. A snow tiller configured to be drawn in a travelling direction along a ski slope to prepare the ski slope, the snow tiller comprising: a plurality of supporting structures, wherein two of the supporting structures are coupled to each other by at least one articulated coupling configured to enable relative movement between the two supporting structures;a plurality of shafts, wherein two of the shafts are respectively housed in and supported by the two supporting structures, the two shafts configured to be rotated about respective rotation axes crosswise to the travelling direction, wherein each shaft includes a flange extending partly between the two supporting structures;a plurality of tools fitted to the two shafts; anda blade fixed directly along a face of one of the two flanges of one of the two shafts, said blade defining two further tools fixed to and extending in opposite directions from one of the two flanges of one of the two shafts, said two further tools each being located between the two supporting structures. 2. The snow tiller of claim 1, wherein each supporting structure respectively includes a bar and a casing fixed to and supported by the respective bar. 3. The snow tiller of claim 2, which includes a supporting bar coupled to the supporting structures by a further articulated coupling configured to support the supporting structures and permit relative movement between the supporting structures and the supporting bar. 4. The snow tiller of claim 3, wherein the further articulated coupling is configured to permit relative movement between the supporting structures in a direction perpendicular to the travelling direction. 5. The snow tiller of claim 1, which includes a joint connected to the two shafts and configured to permit relative angular movement between the two shafts. 6. The snow tiller of claim 5, wherein the further tools are each mounted on the joint. 7. The snow tiller of claim 6, wherein the further tools are each mounted at one end of the joint. 8. The snow tiller of claim 1, wherein the two supporting structures are coupled to each other about at least one hinge axis. 9. The snow tiller of claim 1, wherein the blade has a hollow portion to permit assembly of a joint. 10. The snow tiller of claim 1, which includes a further blade defining another two further tools, wherein the blade and the further blade are positioned at an angle of 90° to each other. 11. A snow tiller configured to be drawn in a travelling direction along a ski slope to prepare the ski slope, the snow tiller comprising: two supporting structures coupled to each other by at least one articulated coupling configured to enable relative movement between the two supporting structures;two shafts respectively housed in and supported by the two supporting structures, the two shafts configured to be rotated about respective rotation axes crosswise to the travelling direction, wherein each shaft includes a flange extending partly between the two supporting structures;a joint connected to the two shafts and configured to permit relative angular movement between the two shafts;a plurality of tools fitted to the two shafts;a first blade fixed directly along a face of a first one of the two flanges of a first one of the two shafts, said first blade defining two first further tools positioned 180° apart, the first blade having a hollow portion to permit assembly of the joint, the first blade being fixed to the first one of the two flanges of the first one of the two shafts, said two first further tools each being located between the two supporting structures; anda second blade fixed directly along a face of a second one of the two flanges of a second one of the two shafts, said second blade defining two second further tools positioned 180° apart, the second blade having a hollow portion to permit assembly of the joint, the second blade being fixed to the second one of the two flanges of the second one of the two shafts, said two second further tools each being located between the two supporting structures, wherein the first blade and the second blade are positioned at an angle of 90° to each other. 12. The snow tiller of claim 11, wherein each supporting structure respectively includes a bar and a casing fixed to and supported by the respective bar. 13. The snow tiller of claim 11, which includes a supporting bar coupled to the supporting structures by a further articulated coupling configured to support the supporting structures and permit relative movement between the supporting structures and the supporting bar. 14. The snow tiller of claim 13, wherein the further articulated coupling is configured to permit relative movement between the supporting structures in a direction perpendicular to the travelling direction. 15. The snow tiller of claim 11, wherein at least one of the two first further tools and the two second further tools is mounted on the joint. 16. The snow tiller of claim 15, wherein at least one of the two first further tools and the two second further tools is mounted at one end of the joint. 17. The snow tiller of claim 11, wherein the two supporting structures are coupled to each other about at least one hinge axis.
