SPRINKLER MACHINE "CASCADE" Russian patent published in 2020 - IPC A01G25/09 

FIELD: agriculture; machine building.

SUBSTANCE: present invention relates to agriculture. Sprinkler machine comprises pivotally interconnected spans comprising arranged on self-propelled cart (1) a trussed girder, consisting of pipeline (2) with sprinklers (3), braces (4), springs (5) and crossbars, made of a piece of pipe with flattened and bottom-bent ends. Spans of pipeline (2) have identical working cross-section and are made of two standard sizes – with length of 59.5 and 65.25 m. Span girder length of 65.25 m is mounted out of ten sections of braces (4), and in span span girder 59.5 m – nine sections of braces (4). In span of 65.25 m, first and last four sections of braces (4), including crossbars included in said sections, are made the same as the first and last four sections of brace braces (4) of 59.5 m. In structure of girders of both spans, pipeline (2) and strings (5) are located along parabolic curve, for this in each section of braces (4), braces (4), having an inclination towards middle of truss, are longer than braces (4) with slope towards end of girder.

EFFECT: creation of two standard sizes of spans different in length and having high degree of unification due to use of identical and universal parts in their design, which will make it possible to more accurately select length of sprinkling machine for size of irrigated area, while ensuring low prime cost and simple design of sprinkler machine.
