SELF-PROPELLED GRADIENT TROLLEY OF MULTISUPPORTING IRRIGATION SYSTEM Russian patent published in 2013 - IPC A01G25/09 B62D57/02 

FIELD: agriculture.

SUBSTANCE: self-propelled gradient trolley of multisupporting multisectional irrigation system comprises a frame (1) with the carrier beam (2) transversely fixed to the pressure pipeline (2) with the racks (3), (4), at the ends of which the gradient supports (5, 6) are installed in pairs comprising the supporting piles (7) and the hinge four-link chains (8, 9) connected to the output shaft (10) of the reducer (11) of actuator (12). The novelty of the invention is that the trolley comprises driving (5) and driven (6) gradient supports, arranged in pairs at the ends of the carrier beam (4), and in the primary gradient supports (5) the hinge four-link chains (8) consisting of the support links (13) formed in the form of double-arm connecting rods, rocker arms (14), the free ends of which are pivotally mounted on the boards to the carrier beam (4), and also the primary cranks (16), connected to the output shaft (10) of the reducer (11) of the actuator (12) by additional mechanisms-correctors (17) in the form of flat four-link mechanisms that transform the uniform rotation into uneven, of containing primary cranks (18) of the mechanisms-correctors (17), the intermediate connecting rods (19) and the driven cranks (20), which are also primary cranks (16) of hinge four-link chains (8) of primary gradient supports (5). The primary cranks (18) of the mechanisms-correctors (17) are mounted on the output shaft (10) of the reducer (11) of the actuator (12) in antiphase, and in the driven gradient supports (6) the hinge four-link chains (9) also consisting of the support links (13), rocker arms (14) and cranks (16), are connected on the boards with the actuator (12) through the hinge four-link chains (8) of primary gradient supports (5) by common supporting piles (7) made ski-shaped, pivotally attached to the support links (13) of the hinge four-link chains (8, 9).

EFFECT: increased energy efficiency of self-propelled multisupporting multisectional irrigation machines with gradient trolleys gradient trolleys of multisupporting irrigation systems.
