SELF-PROPELLED WALKING TROLLEY OF MULTI-SUPPORT MULTI-SECTION SPRINKLER OF CIRCULAR OPERATION Russian patent published in 2013 - IPC A01G25/09 B62D57/02 

FIELD: agriculture.

SUBSTANCE: self-propelled walking trolley of multi-support multi-section sprinkler of circular operation comprises a frame (1) transversely fixed to a discharge conduit (2) with legs (3) of a carrier beam (4), at the ends of which there are walking supports (5) installed in pairs, each of which comprises a support foot (6) and a four-link hinge (7) associated with an actuator (8). The four-link hinge (7) of the walking supports (5) consists of cranks (11) connected with the actuator (8) via a cardan transmission (15), support members (12) are pivotally attached to the foot (6) and rocker (13), the free ends of which are articulated at the board on racks (3). The four-link hinge (7) of the walking supports (5) are arranged in vertical planes of walking, being offset from the longitudinal axis of the carrier beam (4) at an angle $$\alpha =arctg\left(\frac{1}{2(L-\Delta L)}\right),$$ where 1 - length of the carrier beam (4), L - length of one section of the discharge pipe (2), Δ L - the displacement of the end section of the longitudinal axis of the carrier beam (4). Racks (3) have additional holes (18) for the swivel mount rocker arm (13), paired for the left and right sides, the number of pairs is equal to the number of sections of the multi-section sprinkler. The axes of each pair of holes (18) for the swivel mount rocker arm (13) of the right and left sides are made with an offset chosen under the condition $$\frac{S_2}{S_1}=\frac{L-\Delta L+B/2}{L-\Delta L-B/2},$$ where S1 and S2 - length of walking supports (5) pitch, respectively, for lagging and anticipating running boards, B - track width of the walking trolley of the sprinkler .

EFFECT: reduced costs of power per turn, decreased jamming of plants, facilitated unification of actuator elements.
