In order to fill the tank, different pumping systems, such as a vacuum pump, positive displacement pump and centrifugal pump are possible. Veenhuis offer the selection of two vacuum pumps, B&P pump with synthetic blades and the Veenhuis V3 super pump with steel blades that is known for its high vacuum of 96%, low power requirements and long service life. The positive displacement or rotary lobe pump is almost always implemented with a cutting filter. The centrifugal or micro turbo pumps can be used in different ways. For example, they can be used as an auxiliary pump in the suction arm with a vacuum or positive displacement tank. The centrifugal pump can furthermore be used as automatic fillers as well whereby the centrifugal pump is brought into the slurry.
The tanks can be outfitted with two different suction arms: a short suction arm and a buckling swiveling arm. Both arms can optionally be outfitted with a centrifugal pump, a 10” suction hose, and aeration crane. The tanks can also be outfitted with a so called docking system. Hereby the docking arm is placed in a funnel at the well or silo, or in a funnel at the supply tank.
The basic operation of a fertilization tank is hydraulic with a manifold block that can be expanded with a simple electronic drive. The CAN-Bus control system that Veenhuis developed can also be selected. This is a very reliable and extremely user friendly control system, with a light and compact control cabinet to enter time and dosing adjustments.
Adjusting the slurry provision can be achieved by using different dosing regulations. A manually operated valve with a pin hole adjustment with which the driving speed in combination with the delivery is regulated. On the other hand, it can be an automatic dosing regulation that measures the manure provision via a pass-through meter. Adjusting the delivery can be done using an electronically operated ball valve on the tank. The automatic dosing regulation can be linked to the LH Agro 5000 as well as the Veenhuis CAN-Bus system.
The most frequently applied lifting device on tanks is the 4 points lifting device. There is a lighter implementation for a light tank such as the EcoFarm and a heavier implementation for the heavy tanks. But also other (3 points) lifting devices are applied to certain types of tanks. The depth regulation can be adjusted in different ways. The depth is adjusted standard using a pressure reducing valve. Optionally a proportional regulation with reversed coulter pressure can be delivered, which during operation can be regulated to be operated completely continuously from the cab.
In order to improve the driving comfort of the tank, the tanks can be outfitted with a hydraulic pole spring with top pressure cylinder. The pole spring cushions the shocks between tank and tractor, the top pressure cylinder transfers the weight to the front wheels so that a better grip to the field occurs and even less shocks on the road. The tandem tank is outfitted with blade or hydraulic springs and has move along or forced operation. The tridem and 4-axle tanks come standard with hydraulic springs, and are outfitted with forced operation. Optional on a large number of tanks are an axle lift and tyre pressure exchange system.
Weighting and sampling
In connection with the various issuing rules most of the Veenhuis tanks can be outfitted with weighing, sampling, and GPS equipment.
