Il restyling della testata Diamant

The Piedmontese company Capello – headquartered in Cuneo – specializing in the construction of grain harvesting equipment, will be presenting several new products at Agritechnica. We start with the new 16-row DIAMANT corn header tipping system, equipped with an innovative lever technology for closing the header. Inspired by devices used to move large loads at construction sites, Capello designers have repositioned the hydraulic cylinders of the header, no longer arranging them horizontally but vertically, above the frame. This particular construction solution – explains Capello in a technical note – reduces the hydraulic pressure required during the opening and closing phases of the DIAMANT header, and at the same time lightens the frame. The fulcrum points allow the cylinders and levers to work optimally. Furthermore, the levers are not welded but built into the cylinder head structure itself and joined with screwed bushings, and this – as stated in the Capello technical note – significantly increases their resistance. The components of the new leverage system are lightened and sized in such a way as to minimize the weight in play, which is extremely important for equipment that works in a "cantilevered" manner on a combine harvester or a self-propelled forage harvester. Another important innovation introduced by the Piedmontese manufacturer on the Diamant header concerns the transmission box, which has been modified to ensure compatibility with the main combine harvester models on the market. The modules that make up the box are made of aged aluminum alloy and are obtained with a single casting. The gears are of the straight-tooth type and are equipped with roller bearings, which improve the efficiency of the box with less energy dispersion and a consequent reduction in consumption. The hydraulic system for moving the deck plates has a double cylinder, so that the plates can move simultaneously and synchronously during the harvesting phase. Depending on the type of product being worked, the operator decides the opening of the stalk plates which, moving in a synchronized manner, center the stalk of the corn plant with respect to the working axis, without loss of grain and without the entry of residues. Among the models featured at the Capello stand, a special mention goes to the folding platform for harvesting straw cereals, the Grain System Evo, which features a suspended frame - no longer suspended like other models - which frees up space inside the collection tank, thus improving the flow of the product into the feeder channel. The bottom of the frame, made of stainless steel, is also equipped with a stone guard that prevents stones or other objects from entering and damaging the internal moving parts. In addition to making the flow of conveyed material more uniform, the solution adopted by the Cuneo-based company significantly increases the combine harvester's forward speed during the harvesting phase, without compromising its quality. The new RUBIAN flexible conveyor cutting platform will also make its debut in the Piedmontese company's exhibition spaces at Agritechnica.
