Seeder LR803


Seeder LR803

3-roller electronic seeder, built on the basis of the high-performance and versatile LR800. Equipped as standard with Mitsubishi Electric® PLC, inverter, driver and touch screen.

3-roller version of the LR800, this seeder can be integrated into any line like other seeders.
In the illustrated version it’s inserted inside a sowing line, combined with the filler mod. RC800 and roller vermiculite coating mod. GRR.
The simultaneous presence of 3 drums makes the LR803 the most suitable machine for managing, in the same sowing cycle, seeds of different sizes which therefore require different drums.
The other important advantage is the possibility of always being able to manage trays with staggered holes, regardless of the number of holes present along the length of the tray.
According to the customer’s needs, it can also work with a single roller or 2 rollers. All directly manageable from the touch screen.
The dibbling system is a mobile plate, i.e. this moves together with the tray for a section of its advancement: this has the great advantage of combining the peculiar characteristics of the dibbling plate (modulation and precision) with a speed of 800 trays per hour.

The LR803 are equipped, on the seed drum, with a brushless motor with independent speed from that of the belt to ensure maximum precision and modulation of the work cycle.

The hard-anodized aluminum sowing drums can be with 10 or 20 slots.
Stainless steel inserts are used for the smallest drilling diameters.

Overall, the line has been designed with particular attention to ergonomics and maximum containment of the time needed to carry out the routine operations involving the sowing cycles.
The change of the drums, the plate and the seed are therefore intuitive and fast, while the recipe data, managed by PLC, can be easily managed at any time.
The presence of the PLC then allows, upon request, the connection with the Company servers via Modbus TCP® or OPC UA ® system
