Feed conveyor VK920

for firewoodrollerwith hydraulic adjustment

The centring infeed conveyor ensures a good grip of the log at the start of the debarking phase and an accurate control of log onto the debarker’s infeed line. VK infeed conveyors centre the logs both vertically and horizontally (X–Y centring) using a conveyor trough and a flap/roll, which places pressure on the log. The feeding of logs into the debarker is aided by the shape of the infeed conveyor’s flight chain – the flights push the logs forward. The infeed conveyor model VK920 was introduced onto the market in the end 1990s. The model is an extra strong conveyor and it was specifically designed for large logs. The conveyor is supplied as standard equipment for machine models VK8092HD and VK8092HDSL as well as VK8000HD-Combi-2R (if the rotor type is 5092, Air Seal). VK infeed conveyors’ power transmission is handled using a worm gear. The conveyor’s drive sprocket is connected to the gear with a purpose-built cardan shaft. The power is transferred from the electric motor to the gear by V-belts. The pressure of the VK infeed conveyors is produced hydraulically. All VK infeed conveyors feature a pre-opening function of the flap. This function is required when debarking at a high feed speed or when feeding small or light logs in. In the VK920 conveyor model, a log’s approach is detected by photo cells at the start of the conveyor. The VK920 conveyor can also be installed on the old debarkers as a retro-fit package.
