APPARATUS FOR WATERING IN GREENHOUSES

摘要

The sprinkler system installed under the greenhouse ceiling includes a sprinkler unit having many sprinkler nozzles fixed to a water pipe, a movable carrier frame unit having a rive motor, a pump and a rechargeable battery, one or two trough-like water tanks installed on the upper side walls to have flat rail strips for rollers. The system moves the carrier unit with the sprinkler unit hanging underneath by the battery powered motor and a chain and spracket arrangement to travel back and forth on the rails and pumps water out of the trough tank and sprinkle through nozzles. The system operation is manipulated from a control panel on the inner wall. The system eliminates hazards of dragging a long water hose and power line.
