Adjustable Film Layer for Low Tunnels (Mechanical functioning)

Cosmeco film layer for small tunnels is of great help in the protected agriculture field in particular for the forcing and semi-forcing cultivation techniques, namely those applications that – as well as protecting plants from low temperatures – speed up the harvest of a few weeks.

Our adjustable film layer is made of a simple frame, modifiable both in height and width. It’s equipped with a series of descending wheels which lead downwards and stretch the sheet to the ground, there the film is earthed up and secured by means of the two milling rotors set on both sides of the machine. The result is a low tunnel, semi-cylindrical in shape and with a maximum height of 55 cm, supported by small plastic or iron arches which are manually and pre-emptively inserted into the ground by an operator.

The fabrics used range from PVC to PE, but also EVA or TNT Agrotextile; this last one is extremely light, made for the most in polyester fibres, and this equipment can lay it down directly on the crop even with no supporting arches.

The efficiency of this machine, combined with its simplicity, makes our film layer a successful device used in many different fields, such as: horticulture, agriculture, nursery, floriculture, and flower ornamental crops.

Technical Aspects:

• Transmission with cardan shafts and oil-immersed gears
• 2^nd category three-point hitch
• Minimum centre-to-centre distance: 230 cm
• Maximum tunnel height 55 cm (depending on the height that the tractor allows)
• Reel width 220 cm max.

Main Strenghts:

• The mechanical functioning doesn’t risk the overheating of the components, even in case of work with high temperatures
• Suitable for all kind of soils
• Also useful for mulching on flat ground
• Possibility of creating low tunnels in different sizes with the same equipment, thanks to its adjusting system
• Maximum output in open field
• Reduction of working time up to one third with respect to the manual system, with consequent additional anticipation of the harvest time.

On Demand:

Cardan shaft with safety bolt – Support for spare film reel – Rear simulator for TNT film laying without arches – Compact crankcase for milling rotor – Rear wheel hydraulic adjustment

We also design and develop on demand solutions, in order to satisfy all of our customers’ desires and requests: widened chassis, special lead angles, extra accessories or any kind of particular equipment which are not part of the standard production line.
