The invention discloses a corn and soybean strip-shaped compound planting full-
plant-protection spraying
system. The
system comprises a power
machine and a spraying mechanism arranged at the front endof the power
machine, and the spraying mechanism comprises a
parallelogram lifting adjusting mechanism, a
cantilever swing adjusting mechanism, a three-dimensional turnover mechanism, a middle
pesticide spraying support, a check curtain mechanism and a spray head
system. The spraying mechanism can be lifted or lowered by controlling the
parallelogram lifting adjusting mechanism, and meanwhile thespraying mechanism is suitable for
pesticide application operation on short straws and suitable for
pesticide application operation on the high straws and the short straws at the same time; when spraying operation is carried out in the earlier stage of corn and soybean interplanting, a
cantilever is unfolded, lower spray head sets on the two sides are used for spraying, and when spraying operation is carried out in the later stage of corn and soybean interplanting, the
cantilever is folded, the three-dimensional turnover mechanism and three-dimensional turnover spray head sets on the two sides are used for spraying corns, and a spray head set in the middle is used for spraying soybeans; and during transportation or walking, the cantilever and a upper cross rod are folded to be perpendicular to a lifting frame simultaneously.
