Zaadvakken

Zaadvakken are seed compartments used in agricultural sowing equipment, such as seed drills and planters. In Dutch terminology, the vak (compartment) holds a defined quantity of seeds and feeds them into the metering mechanism that determines the dose delivered to each furrow. Zaadvakken are typically arranged along the seed distribution head and are associated with individual rows or metering channels.

Function and design

The primary purpose of zaadvakken is to regulate the flow of seeds and ensure uniform emergence by delivering a consistent seed rate per unit of area. The compartments are designed to be filled with a specific seed type, and their volume can often be adjusted to accommodate different seed sizes and target seeding rates. Materials most often used are durable plastics or metals, chosen for wear resistance and ease of cleaning. In modern machines, zaadvakken may be part of rotary, cup, or finger-metering systems, and they can be swapped or recalibrated to accommodate different crops.

Operation and maintenance

Accurate calibration of the zaadvakken is essential for achieving the desired seeding density. Operators adjust volumes and verify with calibration tests, especially when switching seed varieties. Regular maintenance includes keeping the compartments clean, dry, and free of seed bridging or moisture buildup, inspecting for wear, and replacing worn components. Proper storage and handling help prevent contamination and degradation of seed quality.

Applications

Zaadvakken are used across mechanized agriculture for row crops and other seeding operations. They support consistent spacing and germination by providing uniform seed delivery, contributing to efficient field emergence and harvest yields.
