FIELD: agriculture. ^ SUBSTANCE: dropping bottle comprises watering pipeline provided with outlet port and device for filling the watering pipeline with water. The device is made of a sleeve finned from the outer side. The finned surface is conjugated with the inner side of the pipeline. The ring grooves interposed between the pairs of the ribs are made of rings arranged at the ends of the sleeves and are connected with its space through radial openings. The outlet port made in the wall of the watering pipeline provided with a ring groove at one of the ends of the sleeve is connected with the labyrinth passage. The sleeve mounted in the space of the watering pipeline is locked by means of a bandage that embraces the outer side of the watering pipeline and is mounted on the second end of the sleeve. The entering chamfering of the bandage lies above the outlet port of the watering pipeline. The second ring groove interposed between the pairs of the ribs on the outer side of the sleeve is provided with the valve made of a flexible cord. The cord embraces the outer side of the sleeve in the ring groove. The bandage and the wall of the pipeline is provided with a conical opening. The top of the conical opening is oriented in radial opening in the second ring groove. The angle at the top of the conical opening in the bandage is equal to 45-70°. When pressure of water does not exceed 0.02 MPa, the dropping bottle provides droplet spraying, and when the pressure in the pipeline is 0.05-0.08 MPa, it provides finely divided spraying. ^ EFFECT: increased crop capacity. ^ 3 cl, 4 dwg |
