AUTOMATION OF SULKY FERTILISER SPREADER

AUTOMATION OF SULKY FERTILISER SPREADER

Through close collaboration, LINAK and Sulky F&E have succeeded in automating all the control processes involved with the fertiliser spreaders. Using multiple integrated LINAK electric actuators and a connection technique developed by Sulky.

Opening and closing of the intake and the regulation for the quantity of administered fertiliser (corresponding to the driving speed and the number of partial widths) occurs by actuators adapted to the conditions of the work environment.

MORE COMFORT AND HUMAN ENGINEERING

Both companies decided to use the compact and easy to integrate LA12 actuator. The farmer can set the preferred rotation speed for comminuting and mixing the feed. Directly from the driver's cabin of the tractor. This saves time and is an ergonomic and comfortable solution.

This mechanism provides an inexpensive solution that is qualitatively comparable to hydraulics. The robust housing is also dust resistant and can provide a level of protection corresponding to IP66 dynamic and IP69K static.

EFFICIENT AND COMFORTABLE HARVESTING

EFFICIENT AND COMFORTABLE HARVESTING

The Belgian AVR Company has developed harvesting machines for the potato harvest since the second half of the 20th century.

In the past, a great deal of manual labour was required for potato harvesting. Currently, the four-rowed self-propelled Puma 3 harvester from AVR carries out the complete potato harvest with impressive efficiency.

Puma 3 makes use of actuators from LINAK for many different tasks.

"Electric actuators are becoming ever more important", notes Stefan Top, Managing Director of AVR."They are simple to apply and can be easily integrated."

He especially values the functional reliability of LINAK actuators."The actuators have become increasingly more robust in recent years, and this is very important to us."

The machinery is becoming larger, more complex and more efficient.

MIEDEMA: BETTER WORK PROCEDURE WITH LINAK ELECTRIC ACTUATORS

MIEDEMA: BETTER WORK PROCEDURE WITH LINAK ELECTRIC ACTUATORS

Planting elements and planting distance must be individually varied when optimising the crop and potato size. The machine's planting elements may be switched on and off individually. The mechanism for this system has been automated by means of two electric adjusting actuators from LINAK. 

They are directly connected to the Miedema control system can be operated from the tractor's touch panel in the cab.

Miedema engineers have made explicit use of electric adjusting actuators in developing row deactivation. Unlike a hydraulic system, integration in the electric control unit is significantly easier and less expensive. In a hydraulic system, two connections must be made. In an electric actuator, only one is needed. 
 

LINAK LINEAR ACTUATORS - IN NEW HOLLAND COMBINE HARVESTER

LINAK LINEAR ACTUATORS - IN NEW HOLLAND COMBINE HARVESTER

New Holland uses electric actuators in combine harvesters. Alongside ease of integration, there are in particular the multiple options for control that favour an electric actuator. Adjusting, positioning, moving - electric actuators perform a range of tasks in a combine harvester. And, this will certainly increase in the future. Michaël Carpentier, Product Development Manager at New Holland in Zedelgem, Belgium, is convinced of this fact. He and his team investigate the best ways to make a combine harvester even more efficient, environmentally sound and comfortable for the operator. The use of electric actuators is important in this regard. Precise setting of the machinery is especially important for achieving the best possible yields, and precise positioning plays a key role here. LINAK electric actuators LA36 can provide precise positioning. This task is performed considerably better than hydraulic systems in which feedback and positioning require considerable technical complexity. Since feedback on position can be provided as either an analogue or a digital signal, integration into the bus controls can be performed without difficulty. A major application for an electric actuator in a combine harvester involves, for example, a straw distribution system. On request, New Holland combines offer the Opti-Spread straw spreader, which is attached behind the straw chopper. The farmer is able to control the width and direction of straw ejection. Two powerful spreader discs are set with the aid of LINAK actuators LA36.
