Watering and covering machine used to water and cover previous seeded trays with for example vermiculite.
The machine is constructed out of painted steel. The trays are transported by a conveyor belt that is made out of plastic links. The  watering cabin contains 5 nozzles, which are independently controlled for a perfect control of the watering of the trays. A mechanical switch triggers the nozzles. A drip bin is mounted underneath the tunnel to collect the spilled water.  The hopper that is mounted above the conveyor belt holds the vermiculite. Inside the hopper a conveyor belt is transporting the vermiculite to the output side. By changing the opening of the output gate the amount of output is changed. The guide plates inside the hopper will determine the width of the output flow. The clearance underneath the hopper is adjustable, by 2 cranks. Excess Vermiculite will fall through the conveyor belt and is collected in a plastic bin underneath the conveyor belt.  The plastic bin is accessible by a two doors on the side of the machine.
A mechanical switch is used to detect a tray. When a tray is detected, a timing delay will activate the hopper. The hopper is turned off after a pre-set time, which is set at a timer in the control panel.
