FIELD: agricultural engineering, in particular, technique for cutting of temporary irrigation system, may be used for opening of terrace and closing of temporary irrigation system with ground.
SUBSTANCE: apparatus has frame hung laterally onto tractor girder, hydraulic cylinder for lifting of apparatus, and shield pivotally connected to stem of hydraulic cylinder. High-quality closing is provided by fabricating shield from two parts unequal in length, said parts being pivotally connected to frame of apparatus. Compression spring attached to shield and shield rotation limiting device provide returning of shield after executing of closing procedure to position perpendicular to frame of apparatus.
EFFECT: improved quality of covering irrigation system terrace, and reduced costs for strip irrigation process.
