MULTISECTION SPRINKLING MACHINE OF CIRCULAR ACTION Russian patent published in 2017 - IPC A01G25/09 

FIELD: agriculture.

SUBSTANCE: multisection sprinkling machine of circular action contains the central fixed support with a swivel knee and sprinkler nozzles. The nozzles are installed on the pipeline sections. The pipeline sections are successively connected to each other and placed on self-propelled trucks. The trucks are driven by an electric motor. On the free ends of each pipeline section, two eyes are welded. The eyes in their lower part are rigidly connected to each other by two bushings. The bushings on the eyes at the beginning of the section are located in one vertical plane. On the eyes at the end of the section, the bushings are located in one horizontal plane. U-shaped elements previously engaged with each other, with the stops arranged thereon, are fixed in the bushings. The cavities of adjacent pipeline sections are connected by means of rubber couplings. At the upper part of the eyes at the pipeline section end, a platform is welded. A vertical rotary axis is installed on the platform. The symmetry axis lies on one vertical axis with the hinged connection center. The upper part of the vertical rotary axis is pivotally connected to the intermediate link. The intermediate link is pivotally connected to the lower link. The lower link is hinged at the beginning of the next adjacent pipeline section. A control lever is rigidly fixed on the vertical rotary axis. The lever interacts with the control unit. The control unit is fixed with screw clamps on a horizontal rail. The horizontal rail is rigidly connected to the upper part of the platform and serves for moving the control unit over it when adjusting its sensitivity.

EFFECT: possibility of adjusting the sensitivity of the control unit, reducing the hydraulic resistance when transporting water through the pipeline.
