High speed distributor

Inside the metering unit, behind the seed disc, a vacuum attracts and picks the seeds through the plate holes. Its set up depends on:

 

Diameter, weight and shape of the seed;

Number of holes on the seed disc.

 

Depending on the type of seed, it is possible to adjust the air flow. The flow of air will be less important for rapeseed to prevent the seed from bouncing in the furrow and vice versa, the air flow will be stronger for a corn seed. This independent compressed air circuit, with adjustable flow, allows the drill to adapt immediately to each crop.

The photocell at the exit of the metering unit checks the actual passage of the seed in the seed tube through the lighting of a led. It allows a real-time data collection regarding number of seeds, distance and precision. An audible alarm warns in case of problems in the system

MOTORE BRUSHLESS Open Close

TRONICbrushlessdrive

MOTORE BRUSHLESS

Gaspardo equipaggia le sue seminatrici a trasmissione elettrica ISOTRONIC con dei motori brushless (privi di spazzole di sfregamento) di alta qualità da 12V. Questa tecnologia permette una facile ed immediata gestione e controllo delle file tramite protocollo ISOBUS. Ogni singolo motore è gestito elettronicamente dalla centralina e consente di escludere ogni fila in qualsiasi momento.

I vantaggi di un motore brushless sono:

  • L’assenza di spazzole di sfregamento, che determina una durata a vita delle componenti, senza necessità e costi aggiuntivi di manutenzione.
  • Un motore a tenuta stagna, che riduce problemi ed inconvenienti dovuti ad infiltrazione di polvere durante l’uso o a getti d’acqua durante il lavaggio.

Maximized accuracy

The volumetric lobe compressor creates an adjustable airflow in the seed tube that transports seeds from the metering unit to the seeding furrow. Rebounds and slowdowns are avoided thanks to this constant airflow: two independent systems manage the vacuum of the metering unit for seed selection while the pressurized air flow transports the seeds through the delivery tube to the furrow.

The seeds are released by the distributor to the straight seed tube with zero friction, thanks to the 15° angle that features the metering unit. In the first section of the tube a vacuum sucks the seeds downwards; in the second part, instead, an airflow leads them effectively towards the furrow with an operating pressure of the system that can vary from 75 up to 400 mbar, totally independent from the vacuum circuit.

With CHRONO the seed spacing will be therefore perfectly uniform.

The regulation of the airflow depends on:

- Working speed;
- Planting depth;
- Size and shape of the seed.

CHRONO - Tilted metering unit with electric transmission

The metering unit has been designed to reduce wearing of components and to guarantee the best reliability in every working condition.

A single electric motor drives the seed disc. The seeds are released by the 15°-angled distributor to the seed tube without any friction. The 5 tips selector guarantees one seed for hole. The integrated rotating gasket allows wearing reduction.

The design Open Close

The design

The CHRONO precision planting unit is the result of the cooperation between MASCHIO GASPARDO R&D and SID Italian School of Design. The cutting edge design ensures the best performanceease of use and ergonomic results for the operator.

The CHRONO design and name express dynamism, speed and precision. The remarkable and unique style offers a modern and innovative look.
