Technique of the Wingssprayer

Spraying crops

Spraying crops with the Wingssprayer provides a fine coverage of many small droplets. Due to this, the crops are optimally protected. Normally, a disadvantage would be that these small droplets easily drift off and have a negative effect on the surrounding area. The Wingssprayer Wings prevent drift towards the surrounding area, whereby the protection product only ends up inside the crops. The Wingssprayer does this by using the air stream that arises during driving. The downwind makes sure the spraying fluid is sprayed right into the crops, while at the same time, the crops are moved.

Technique further developed

The Wingssprayer has been developed to enable a faster and more efficient way of spraying agricultural crops. This sets significant larger demands to the spraying technique. In the further development of the system for the single Wing, which is suitable for travelling speeds up until 15 km per hour, the Wingssprayer Double Wing has been designed, which is suitable for much higher travelling speeds.

Wingssprayer Double Wing

The Double Wing is a double wing construction that uses the air streams that arise during spraying, by the driving wind and the speed of the spraying machine.

Comparable to airplane wings

As opposed to airplane wings, these Wings don’t use upwards force, but downward airstreams, the downforce. These streams make sure that the fine droplets go straight into the deepest parts of the crops.

Higher speeds

With the Double Wing it is possible to spray the crops at much higher speeds. Because of the contact with the crops, the spraying boom is stable. When the Wings come loose from the crops, the wing stabilizes by the anti-pendulum dampers that are mounted in the suspension. When driving backwards and when turning on the headland, the Wings can move freely and turn away, so no damage to the technical construction will be caused.

Largest environmental profit

The largest profit for the environment is that the driving wind helps to steer the drops into the crops. The driving wind moves the crops at the front of the Wing and behind the Wing; the air directs the drops into the opened crops. In addition, the aerodynamic airstreams form a blanket of air over the crops behind the spraying machine, making sure mist drops can no longer escape from the crops. Due to the fineness of the droplets, there’s no more spraying fluid dripping to the ends of the leaves and less spraying fluid ends up on the ground.

Production requirements

In order to meet the Programme of Requirements (PvE) for the production of the Wings, the material has been adjusted. To decrease the weight, the choice is made to produce both the Single as well as the Double Wing out of high-quality plastic that is also used in the highly demanding aviation industry. For the steal parts we chose stainless steel. In this the Wingssprayer meets the PvE as well. Everything is thoroughly tested and a number of systems have been working to our full satisfaction for years now. Because of this there’s now an extra demand for the Wingssprayer and an increase in production is needed. The production process of almost all parts is subcontracted to acknowledged specialists. 

Acknowledgement and patents

Meanwhile the Wingssprayer has shown that the new technique offers the highest protection to the environment, its users and especially to the water quality. The Wingssprayer generously complies with all requirements. Thereby, the Wingssprayer has received acknowledgement of the Technical Committee Technique Assessment of the Dutch Central Government.

The Wingssprayer Company has various patents for its techniques. This concerns Dutch as well as European patents and the most important ones were requested and acquired worldwide. Thus the Wing technique is extensively protected.
