HYDRAULIC BOOM SPRAYER MODULE Russian patent published in 2023 - IPC A01M7/00 

FIELD: agriculture.

SUBSTANCE: hydraulic boom sprayer module contains a parallelogram hinge-lever mechanism, including a pair of upper parallelogram levers, a pair of lower parallelogram levers, the fixed hinges of which are connected to the module frame, and module supports are installed on their movable hinges, a pair of hydraulic cylinders for raising and lowering the boom, the rods of which are connected to a pair of upper parallelogram levers. The hydraulic cylinder housings are connected to the module frame. The module support is connected from above to a horizontal suspension beam, on which the rod frame is suspended using a pair of suspension rods. On the rod frame, symmetrically relative to the vertical axial plane, fixed using pairs of hinges with a vertical axis, rod frame racks are installed with the possibility of rotation at an angle from 0 to 90 degrees using horizontally located hydraulic cylinders in the horizontal plane, to which cable lever supports are attached from above, with the possibility of rotation at an angle from 0 to 45 degrees, to which the cable levers are attached in the middle part with their lower part with the possibility of rotation, the upper part of which is connected by springs to the upper part of the cable lever supports, and on the other side with shock absorber rods, which are connected by housings to the bottom of the cable lever supports. On the other hand, the lower parts of the cable lever supports are connected to the rods of the boom tilt hydraulic cylinders, the housings of which are pivotally connected to the rod frame racks in the area of the lower rotary hinge. A pair of shock absorbers are installed on the rod frame symmetrically relative to the vertical axial plane, the lower part being hinged in the centre of the lower part of the rod frame, and the upper parts being hinged in the centre of the module support struts. The rod cups are hingedly connected to the lower part of the rod frame racks, into which internal pipes are inserted at one end, the other end of which is connected to the rod hinges, to the other side of which the outer pipes are attached. Two pairs of suspension cables connect the upper parts of the cable levers and the rods of a pair of rod hinges at the point of attachment of the bodies of a pair of rod opening hydraulic cylinders, which are connected with their rods to the hinge scissors mounted on the rod hinge. On the other side, the rod hinge rods are attached to the rod hinges at the point where the internal pipes are connected to them. A pair of inner pipe cables are fixed with one side on the inner pipes in the area of connection of the boom hinges with the housings of the boom opening hydraulic cylinders, and with the other side in the upper part of the transport rod supports mounted vertically on the inner pipes. A pair of support cables connect the upper parts of the transport boom supports and the middle parts of the boom frame racks. A pair of parallelogram clamps are secured to the upper fixed hinges of the module frame.

EFFECT: creation of a hydraulic boom module with increased load-bearing capacity and stability of the boom in the vertical and horizontal planes, with a reduced period of stabilization of the boom in space when processing areas of the field with an uneven surface, increased quality of spraying and durability of the spraying equipment on fields with different categories of complexity and cultivation culture.
