Spray Line and Nozzle HoldersThe spray booms are fitted with a stainless steel spray line with an internal diameter of 18 mm. The ends of the spray lines have removable end stops (A), which allow for easy cleaning of the lines. The sprayboom is always fitted with two connections (left and right), prepared to retrofit edge nozzles. At the end of the sprayboom a single nozzle holder with blind cap (B) is fitted. Nozzle holdersThe nozzle holders are spaced at a distance of 50 cm. The nozzle holders have bayonet caps and are either single nozzle holders or revolving nozzle holders. The nozzle holders are fitted with a diaphragm valve, to prevent the nozzles from dripping after the sections have been closed off. The diaphragm is enclosed in a screw cap to allow for quick and easy cleaning, checking or defrosting. Stiff, damaged or encrusted diaphragms or worn springs are usually the causes of dripping after use. The opening pressure of the diaphragm valve is approx. 0.7 bar.

Single nozzle holder When changing the nozzle on a single nozzle holder (A), the bayonet cap of the nozzle holder (orange as standard) must be removed. The replacement bayonet cap with a different colour and spray tip can then be attached. The correct angle of the nozzle in relation to the spray line is pre-set in the bayonet cap, so that the nozzle automatically points in the right direction in relation to the spray line when the bayonet cap is attached to the nozzle holder, thus avoiding interference of the individual nozzle spray patterns. Make sure the bayonet has the right seal and that the seal is correctly positioned in the cap. There are various types of bayonet caps with specific seals for various types of nozzles. |

Revolving nozzle holder Revolving nozzle holders can be fitted to the machine as an alternative. With such a revolving nozzle holder (A), the carrousel can be rotated to choose a different nozzle. The carrousel may only be turned when it is not under pressure (i.e. do not move the carrousel while spraying!) The revolving nozzle holders have five nozzle connections. The nozzle pointing downwards is the one which is active. There is a blind position between each spraying position. The carrousel can easily be removed from the nozzle holder once the retaining clip (B) has been removed. Plug (C) can then also be removed from the front of the nozzle holder. This allows for simple cleaning of the nozzle holder. The caps fitted to the revolving nozzle holder have a bayonet connection. The correct angle of the nozzle in relation to the spray line is pre-set in the bayonet cap, so that the nozzle automatically points in the right direction in relation to the spray line when the bayonet cap is attached to the nozzle holder, thus avoiding interference of the individual nozzle spray patterns. Make sure the bayonet has the right seal and that the seal is correctly positioned in the cap. There are various types of bayonet caps with specific seals for various types of nozzles.

Position bayonet caps on nozzle holders
NOTE: Don't use the protective cap placed in the nozzle body as "blind" position, the cap will be pushed out of the nozzle body. Crop damage may occur. The multiple nozzle holders are equipped with protective caps (A) to prevent dirt entering the nozzle body. Protective caps are placed in the nozzle body if not all positions are filled with caps and nozzles. If the nozzle body is afterwards equipped with an additional nozzle, seal and nozzle cap, the protective cover has to be removed e.g. with a small screwdriver. Bayonet caps for the nozzle holdersThe bayonet caps which are supplied with the different nozzles are available in black (WZ1900031), red (WZ1900033), blue (WZ1900034), green (WZ1900035), yellow (WZ1900036) and orange (WZ1900038) for TEEJET ® flat fan nozzles. The following nozzles can be mounted in these bayonet caps:
Other bayonets are required for the use of other types of nozzles, such as air induction (venturi) nozzles, deflector nozzles, hollow cone nozzles, twin orifice flat fan nozzles, etc. Contact your dealer on this if required. |
