SELF-PROPELLED GRADIENT TROLLEY OF MULTISUPPORTING MULTISECTIONAL 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) fixed to the pressure pipeline (3) with L-shaped rack (4) located offset with respect to the longitudinal axis of the carrier beam (2) at the ends of which gradient supports (5, 6) are installed in pairs comprising the supporting piles (7) and the hinge four-link chains (8) connected with the actuator (9) of the course movement. The novelty of the invention is that the trolley comprises a motion control system (10) enabling the irrigation machine to adapt to the field shape, comprising adjustment electric drive of the course movement (11) of gradient trolley and the additional drive of rotation (12) of the gradient trolley with respect to the section of the pressure pipeline (3) with the angle of rotation sensor (13). The electric drive of the course movement (11) is made, for example, in the form of a combined motor reducer (14) with adjustable rotational speed on the output shaft (17) of which the antiphase cranks (18) are secured of one pair of gradient supports (5) which are driven, at that the drive of the second pair of gradient supports (6) located at the opposite end of the carrier beam (2) which is driven, is carried out through the principal gradient supports (5) through common supporting ski-shaped piles (7) serving to reduce the pressure on the ground, which are pivotally attached to the support links (19) of hinge four-link chains (8) of each side by means of resilient hinges (20), for example rubber-metal. Additional drive of rotation (12) is made in the form of a linear electric drive (21) hingedly attached with levers (22, 23) on the carrier beam (2) and the L-shaped rack (4) made rotatable relative to the carrier beam (2), on which the angle of rotation sensor (13) of the gradient trolley is also mounted.

EFFECT: increased capacity utilisation of land in the fields of irregular shape and increased energy efficiency of multisupporting multisectional irrigation machines with gradient trolleys.
